This paper presents the results of theoretical studies on rocket/space hardware aerogas dynamics obtained from 2016 to 2020 at the Department of Aerogas Dynamics and Technical Systems Dynamics of the Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine along the following lines: rocket aerodynamics, mathematical simulation of the aerogas thermodynamics of a supersonic ramjet vehicle, jet flows, and the hydraulic gas dynamics of low-thrust control jet engines. As to rocket aerodynamics, computational methods and programs (CMPs) were developed to calculate supersonic flow past finned rockets. The chief advantage of the CMPs developed is computational promptness and ease of adding wings and control and stabilization elements to rocket configurations. A mathematical simulation of the aerogas thermodynamics of a supersonic ramjet vehicle yielded new results, which made it possible to develop a prompt technique for a comprehensive calculation of ramjet duct flows and generalize it to 3D flow past a ramjet vehicle. Based on marching methods, CMPs were developed to simulate ramjet duct flows with account for flow past the airframe upstream of the air inlet, the effect of the combustion product jet on the airframe tail part, and its interaction with a disturbed incident flow. The CMPs developed were recommended for use at the preliminary stage of ramjet component shape selection. For jet flows, CMPs were developed for the marching calculation of turbulent jets of rocket engine combustion products with water injection into the jet body. This made it possible to elucidate the basic mechanisms of the effect of water injection, jet–air mixing, and high-temperature rocket engine jet afterburning in atmospheric oxygen on the flow pattern and the thermogas dynamic and thermalphysic jet parameters. CMPs were developed to simulate the operation of liquid-propellant low-thrust engine systems. They were used in supporting the development and ground firing tryout of Yuzhnoye State Design Office’s radically new system of control jet engines fed from the sustainer engine pipelines of the Cyclone-4M launch vehicle upper stage. The computed results made it possible to increase the informativity of firing test data in flight simulation. The CMPs developed were transferred to Yuzhnoye State Design Office for use in design calculations.

Various technology programmes in Europe are concerned with preparing for future propulsion technologies to reduce the costs and increase the life time of components for liquid rocket engine components. One of the key roles to fulfil the future requirements and for realizing reusable and robust engine components is the use of modern and innovative materials. One of the key technologies which concern various engine manufacturers worldwide is the development of fibrereinforced ceramics – CMC's (Ceramic Matrix Composites). The advantages for the developers are obvious – the low specific weight, the high specific strength over a large temperature range, and their good damage tolerance compared to monolithic ceramics make this material class extremely interesting as a construction material. Different kind of composite materials are available and produced by EADS ST, the standard material SICARBON® (C/SiC made by Liquid Polymer Infiltration) and the new developed and qualified composite materials SICTEX® (C/SiC made by Liquid Silicon Infiltration) and CARBOTEX® (C/C made by Rapid Chemical Vapour Infiltration). The composites are based on textile techniques like weaving, braiding, stiching and sewing to produce multiaxial preforms, the SICTEX® material is densificated by the cost effective Liquid Silicon Infiltration (LSI). Over the past years, EADS Space Transportation (formerly DASA) has, together with various partners, worked intensively on developing components for airbreathing and liquid rocket engines. Since this, various prototype developments and hot firing-tests with nozzle extensions for upper and core stage engines and combustion chambers of satellite engines were conducted. MBDA France and EADS-ST have been working on the development of fuel-cooled composite structures like combustion chambers and nozzle extensions for future propulsion applications.

Launch and space vehicle structures are required to be extremely weight efficient. The need to achieve the performance required for the engine in the upper stage of a launch vehicle, increase the payload capacity drives rocket engine manufacturers to seek higher thrust level, specific impulse and thrust to weight ratio. The use of high temperature C-C composite materials is an efficient way to reach these objectives by allowing use of high expansion ratio. Nozzle extensions benefiting of the outstanding thermal, mechanical and fatigue resistance of these materials to decrease mass and featuring high temperature margins. A three-directionally reinforced (3D) carbon-carbon (c-c) material nozzle exit cone is selected for the current study. C-C composite exit nozzle must possess excellent stability and strength under extreme conditions for a specified amount of time. Carbon-carbon composites are appropriate materials for applications that require high specific strength at elevated temperatures. The paper describes the thermo structural analysis of a typical c/c nozzle exit cone.

Since the earliest days of astronautics, more than a century ago, low cost space launchers persevered to be a long desire for the space flight thinkers. Once space flight became a daily business along the late `50-s, first by consuming large financial resources, the interest for cheap space launchers became even more laud. Today’s growing interest in small satellites have bolstered a large series of space technology companies including Virgin Galactic Corp., Garvey Spacecraft Corp., Quantum Research International, Ventions LLC, Sierra Nevada Corp., Generation Orbit Launch Services and even the giant Boeing to work on the development of various types of such vehicles, some of them of actually small size. They have announced recent progresses in their efforts to develop and test small-satellite launchers and rocket engines. Romanian space launcher effort includes the NERVA project, with the ORVEAL compound engine for the upper stage, securing the orbital injection, project developed by the team of professors and researchers from ADDA Ltd, Bucharest. This project is based on a series of innovative concepts, including the optimal ascent program first proposed by the ADDA team by means of the new discontinuous variational optimization, which is here described in detail.

The article is devoted to an actual problem of clearing of low earth orbits from space objects of a technogenic origin. Existing versions of struggle against space debris, in particular, removal of technogenic objects with help of the special means for deorbiting delivered into a target orbit by launch vehicles that are especially actual for bulky space debris are considered. Recognizing that the ascent of such means for deorbiting by orbital launch vehicles demands large financial expenses, for an increase of efficiency of delivery the means for deorbiting on a low earth orbit widely known sub-orbital launch vehicles are offered: MAXUS, TEXUS (VSB-30), REXUS (Improved Orion), SS-520, MH-300, Black Brant 12А and the estimation of a capability of their application also is conducted. Are considered the use of sub-orbital launch vehicles for the ascent the means for deorbiting on altitudes of a concentration of space debris on a low earth orbit on a trajectory, close to vertical, with the subsequent operations of interception of demanded space objects, and also modernization of launch vehicles by addition of an additional stage. Results of calculations of an injection trajectory of the means for deorbiting in weight in a layer of space debris in altitude 600 … 1200 km showed of 150 kg that sub-orbital launch vehicles MAXUS, SS-520, Black Brant 12A allow executing delivery the means for deorbiting to altitudes from 770 km to 1200 km and to supply time of its presence in a layer of space debris 420 … 850 s. The most perspective sub-orbital rocket is MAXUS. It possesses higher power and a capability of installation of an additional stage by a decrease in weight of a payload with small losses the power of the first stage. It is shown that the given configuration of the rocket with engine thrust specific impulse in vacuum 300 s and engine thrust in vacuum 16 кН is capable to inject into an elliptical orbit with an altitude of apogee 600 km and altitude of a perigee 130 km with a corner of an inclination 5,5 degrees payload in weight of 55 kg. For orbit short circuit in apogee at the altitude, the upper stage should supply 600 km increase the speeds, equal 133 m/s. Mass characteristics of the second stage are induced.

Removing at least half of space debris, consisting of large metal objects, could be a cost-effective activity if, first, it becomes raw material, along with other extraterrestrial resources such as regolith, for the production of heat shields which is aimed to return the upper stages of medium and heavy rockets and, secondly, as a working medium for low-thrust electric rocket engines of interorbital tugs. Heat shields from external resources provide a means of increasing the payload of reusable launch vehicles.

The thrust vector control problem for an upper-stage rocket with propellant slosh dynamics is considered. The control inputs are defined by the gimbal deflection angle of a main engine and a pitching moment about the center of mass of the spacecraft. The rocket acceleration due to the main engine thrust is assumed to be large enough so that surface tension forces do not significantly affect the propellant motion during main engine burns. A multi-mass-spring model of the sloshing fuel is introduced to represent the prominent sloshing modes. A nonlinear feedback controller is designed to control the translational velocity vector and the attitude of the spacecraft, while suppressing the sloshing modes. The effectiveness of the controller is illustrated through a simulation example.

An electrically driven pump-fed cycle for a hybrid rocket engine is proposed and compared to a simpler gas-pressurized feed system. A liquid-oxygen/paraffin-based fuel hybrid rocket engine which powers the third stage of a Vega-like launcher is considered. Third-stage ignition conditions are assigned, and engine design and payload mass are defined by a proper set of parameters. Uncertainties in the classical regression rate correlation coefficients are taken into account and robust design optimization is carried out with an approach based on an epsilon-constrained evolutionary algorithm. A mission-specific objective function, which takes into account both the payload mass and the ability of the rocket to reach the required final orbit despite uncertainties, is determined by an indirect trajectory optimization approach. The target orbit is a 700 km altitude polar orbit. Results show that electrically driven pump-fed cycle is a viable option for the replacement of the conventional gas-pressurized feed system. Robustness in the design is granted and a remarkable payload gain is achieved, using both present and advanced technologies for electrical systems.

The article discusses the issues related to reducing the amount of space debris from rocket stages. The main ways to remove the separable part of a rocket from a space orbit are: the usе of a deceleration detonation propulsion system; gasification of fuel residues and the use of a gas-reactive deceleration pulse system; continuation of the work of the main propulsion system after the separation of stages; the use of a harpoon to capture the rocket stage and the use of sail for its further braking; the use of anti-missile or combat lasers to destroy a stage on the orbit followed by the stage fragments’ burning in the Earth’s atmosphere. To select the optimal method for removing from the orbit the separated part of a space rocket, the arithmetic progression method was applied. It has certain advantages over the classical hierarchy analysis method and has no inherent disadvantages of this method. A ranked row of solutions was obtained according to the five most significant performance criteria, and its stability was proved. A new deceleration detonation propulsion design scheme is proposed. Detonation burning of residual fuel components provides the maximum possible value of the deceleration thrust impulse. Using the example of the second stage of the “Zenit” launch vehicle, we analyzed the nature of the dependence of the entry angle into the atmosphere on the important characteristic parameters: the deceleration speed impulse, the entry speed into the Earth’s atmosphere of the separated launch vehicle stage, the required value of the specific thrust impulse of the deceleration propulsion system. A new analytical formula has been obtained, which connects the thrust and specific thrust impulse values of the detonation engine with the determined detonation process parameters. The results of the computational experiment were compared with the results of calculating the specific thrust impulse using the new formula for oxygen-based fuel compositions, known experimental data, and numerical simulation data of other authors. The data obtained in this study make it possible to evaluate the design parameters of the deceleration detonation engine at the stage of analyzing technical proposals.

In the new conditions of application of launch vehicle boosters, space tugs, etc., modern rocket engines often do not satisfy the current stringent requirements. This calls for fundamental research into processes in rocket engines for improving their efficiency. In this regard, for the past 5 years, the Department of Thermogas Dynamics of Power Plants of the Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space Agency of Ukraine has conducted research on gas flow control in rocket engines to improve their efficiency and functionality. Mechanisms of flow perturbation in the nozzle of a rocket engine by liquid injection and a solid obstacle were investigated. A mathematical model of supersonic flow perturbation by local liquid injection was refined, and new solutions for increasing the energy release rate of the liquid were developed. A numerical simulation of a gas flow perturbed by a solid obstacle in the nozzle of a rocket engine made it possible to verify the known (mostly experimental) results and to reveal new perturbation features. In particular, a significant increase in the efficiency of flow perturbation by an obstacle in the transonic region was shown up, and some dependences involving the distribution of the perturbed pressure on the nozzle wall, which had been considered universal, were refined. The possibility of increasing the efficiency of use of the generator gas picked downstream of the turbine of a liquid-propellant rocket engine was investigated, and the advantages of a new scheme of gas injection into the supersonic part of the nozzle, which provides both nozzle wall cooling by the generator gas and the production of lateral control forces, were substantiated. A new concept of rocket engine thrust vector control was developed: a combination of a mechanical and a gas-dynamic system. It was shown that such a thrust vector control system allows one to increase the efficiency and reliability of the space rocket stage flight control system. A new liquid-propellant rocket engine scheme was developed to control both the thrust amount and the thrust vector direction in all planes of rocket stage flight stabilization. New approaches to the process organization in auxiliary elements of rocket engines on the basis of detonation propellant combustion were developed to increase the rocket engine performance.

The structural and dynamic features of the space (moving outside the dense layers of the atmosphere) stages of rockets - carriers of spacecraft as control objects are analyzed. The reasons are investigated - disturbing factors that generate external forces and moments that determine the disturbed motion of space rocket stages. For space rocket stages, disturbing factors are: mass asymmetry of the stage relative to its longitudinal axis and angle of mismatch of the line of action of the thrust vector of the propulsion system of the stage with the longitudinal axis of the stage. It is shown that when using the stage control deviating in the hinge of the marching engine as the executive organs of the control system, the effect of auto-reduction of the mentioned disturbing factors arises. The consequence of the autocompensation of disturbing factors is the reduction of disturbing forces and moments that violate the programmed motion of the step in the pitch and yaw planes. Mass asymmetry and the angle of mismatch of the line of action of the thrust vector of its engine and the longitudinal axis of magnitude are constant. Therefore, a decrease in perturbing forces and moments is accompanied by a decrease in the amount of energy (fuel) spent on processing (zeroing) perturbations of the parameters of the perturbed motion of the stage. It is shown that if the thrust of a space-stage engine is 8000 kgf, the engine operating time (flight time of the stage) is 500 sec, the specific engine thrust is 330 sec, the mass asymmetry is 0.05 m, the angle of mismatch is 0.25 degrees, then fuel economy can reach 200 kgf. The studies were performed using mathematical modeling methods.

The focus of this research work is to investigate numerically the effect of adding the gas on the design and performance of axisymmetric MLN nozzles. A FORTRAN code was developed to design this nozzle using the characteristics method (MOC) at high temperature. The thermochemical and combustion studies of the most used liquid propellants on the satellites and launch vehicles allow to known all gases. Four engines are investigated: Ariane 5 (Vulcain 2), Ariane-5 upper stage engine (Aestus), Zenit first stage (RD-170) and Falcon 9 upper stage (Raptor). Thermodynamic analysis of parameters design MLN (such as length, Mach number, mass, thrust coefficient) was conducted. The comparison shows that the presence of 50% of H2O gas in combustion species increases the nozzle design parameters (diatomic gas including air) in the order of 25%. On the other hand, the existence of CO2 gas considerably increases approximately 35% the length and the exhaust radius. These rise depend on gases percentage in the combustion. The truncation method is applied in the MLN nozzles to optimize the thrust/weight ratio.

At present, most small satellites are delivered as hosted payloads on large launch vehicles. Considering the current technological development, constellations of small satellites can provide a broad range of services operating at designated orbits. To achieve that, small satellite customers are seeking cost-effective launch services for dedicated missions. This paper deals with performance and cost assessments of a set of launch vehicle concepts based on a solid propellant rocket engine (S-50) under development by the Institute of Aeronautics and Space (Brazil) with support from the Brazilian Space Agency. Cost estimation analysis, based on the TRANSCOST model, was carried out taking into account the costs of launch system development, vehicle fabrication, direct and indirect operation cost. A cost-competitive expendable launch system was identified by using three S-50 solid rocket motors for the first stage, one S-50 engine for the second stage and a flight-proven cluster of pressure-fed liquid engines for the third stage. This launch system, operating from the Alcantara Launch Center, located at 2 ∘ 20’ S, would deliver satellites from the 500 kg class in typical polar missions with a specific transportation cost of about US$39,000 per kilogram of payload at a rate of 12 launches per year, in dedicated missions. At a low inclined orbit, vehicle payload capacity increased, decreasing the specific transportation cost to about 32,000 US$/kg. Cost analysis also showed that vehicle development effort would claim 781 work year, or less than 80 million dollars. Vehicle fabrication accounted for 174 work year representing less than 23 million dollars per unit. The launch system based on the best concept would, therefore, deploy small satellite constellations in cost-effective dedicated launches, 224 work year per flight, from the Alcantara Launch Center in Brazil.

The article examines the influence of the configuration of a hypersonic flight vehicle with a hori-zontal cruise flight section on the maximum flight range under the conditions of limiting dimen-sions. The ram jet and the solid propellant rocket engine were chosen as the cruise engine, and re-spective calculations were performed. The hypersonic flight vehicle was configured based on the design patented in the Russian Federation, under the condition of launch using the 3S14 universal launcher. Dependencies of the maximum range on the ratio between the launch mass to the payload were analysed. The mass efficiency indicator for a two-stage ballistic missile was chosen as a crite-rion for a comparison with other available alternatives.

The successful launching of the new generation of launch vehicle is of great practical significance to the development of China Space, and the cryogenic liquid engine commonly used in the launch vehicle has a certain probability of failures, which may affect the success or failure of rocket launching. In this paper, a Bolza problem optimization algorithm based on Radau pseudo-spectral method is proposed to solve the problem of single engine failure in the first-stage flight phase of the new generation launch vehicle by simulating fault injection and taking the attitude angle as optimal control quantity. The simulation results show that this method can effectively eliminate the influence of single engine failure on orbit injection accuracy, achieve the fault absorption of new generation launch vehicle engine, improve the fault tolerance of attitude control system, and further guarantee the system reliability.

The article presents the results of numerical calculations of the dynamics of in-chamber processes in the cruise missile's second-stage cruise missile propulsion system, taking into account the distributed space-three-dimensional and time-varying flight overloads, obtained using the previously developed calculation method and the application software package created on its basis. The value of the flight overload of a cruise missile, in projections along the coordinate axes, is determined depending on the mass, speed and trajectory of the rocket, mass flow and thrust of the rocket engine. The external aerodynamic effect on the in-chamber process in the SRM is neglected. The results of the calculations are given in comparison-without taking into account and taking into account the effect of flight overload. Two main stages of the rocket engine operation are considered: entering the operating mode and the main operating mode. At the stage of entering the SRM operation mode, the overload affects the redistribution of the temperature of the gas phase of the combustion products in the area of the front bottom of the combustion chamber. On the March operation of the SRB as a result of the flight of an overload, an increase of the particle density (liquid drops) small and large diameter of the solid phase of the combustion products in the wall of the back plate and pre-exhaust gas flue, and the degree of change in the distribution density of the particles (liquid droplets) that are larger than large. The results of the numerical study are in good agreement with the experimental data – the results of bench tests of the rocket engine and the results of flight tests of the cruise missile, which includes the considered SRM.

The role of manned space flight in the field of space exploration and utilization is growing. However, the security system of the manned spaceflight is still imperfect. In the case that the rocket explodes, crew modules maybe damaged by the blast wave, which will threaten the safety of the crews. This research aims to obtain the necessary data and information to enable the designers of the launch vehicles and crew modules to develop safer launch systems. To this end, this paper proposes a numerical method using LS-DYNA to study the propagation law of blast waves caused by rocket explosion on the launch pad and to quantify the impact of the blast wave on crew module. The numerical results indicate that the final blast waveform of the model with rocket is conical in the upper and lower parts, and spherical in the middle. At the same time, the third-stage explosion is the most harmful to the crew module, while the first-stage explosion is the least. Furthermore, the model with rocket has a marked effect on explosion strength: the pressure enhancement factor is about 4–17 times. Most importantly, overpressure prediction formula acting on the crew modulesof explosion on the launch pad is established for quick peak overpressure predicting and damage evaluating.

Abstract This paper presents a systematic formulation for the simulation of rigid body dynamics, including the short period dynamics, inherent to stage separation and jettisoning parts of a satellite launcher. This also gives a review of various types of separations involved in a launch vehicle. The problem is sufficiently large and complex; the methodology involves iterations at successively lower levels of abstraction. The best choice to tackle such problems is to use state-of-the-art programming technique known as object oriented programming. The necessary classes have been identified to represent various entities in the launch vehicle separation process (e.g., gravity, aerodynamics, propulsion and separation mechanisms etc.). Simple linkages are modelled with suitable objects. This approach helps the designer to simulate a launch vehicle separation dynamics and also to analyse separation system performance. To examine the influence of the design variables on the separating bodies, statistical analyses have been performed on the upper stage separation process and pull out of ongoing stage nozzle from the spent stage of a multistage rocket carrier using retro rockets.

The article discusses the problems that arise when creating new models of supersonic and hypersonic aircraft, which can be solved by model high-speed ground track tests. Mathematical modelling of the aerodynamic characteristics of an aircraft (test object) placed on a rail carriage and accelerated by the solid fuel rocket engines is performed. The numerical method solves the problem of the motion of a body of variable mass along a rail track. To determine the required length of the rail track, a mathematical model of the ballistic characteristics of the upper stage of the rocket carriage was compiled, calculations were made, and the influence of various factors on achieving the maximum speed of the test object was analysed. An analysis is made of the influence of the total mass of the carriage with the load and engine thrust on the possibility of accelerating the test object to the Mach speed (4-5).

AbstractEDISON is a large-aperture telescope under study for the second generation of infrared space observatories, whether in orbit or on the moon. The optics equilibrate via radiative cooling to temperatures between 40 and 80 K, depending upon, for example, telescope structure and location. At these temperatures, telescope emission is below that of the astronomical background at all wavelengths shortward of 20-40 μm. The detector components can be cooled via mechanical refrigerators now in an advanced stage of development. A mixture of radiative and mechanical cooling means that there is no natural limit to EDISON’s lifetime. In addition, the upper stage rocket fairing can be almost filled with light-collecting optics and alternative low-emissivity optical designs, such as off-axis systems, can be easily engineered. We are presently evaluating a design for a 2.5 m observatory to be launched in collaboration with European astronomers as part of the NASA Explorer program. In this presentation, we describe possible spectroscopic and spectrophotometric studies of very faint infrared sources that will require large-aperture space telescopes working at the celestial background limit.

One of the topical problems in modern aerospace engineering is accordance between ecological requirements and performance of the vehicle. On the other hand, problem of economical efficiency leads to change of the main criterion of designing to the minimization of costs (instead of maximal performance). According to modern trends of “low-cost” vehicles, different concepts of the future cost-effective launch vehicles are considered. It is necessary to validate these concepts according to requirements of ecological safety for the purpose of detection of the dominant launch vehicle configuration. Typical configurations of the future 'low-cost' launch vehicle are presented by 6 conceptual groups (Koelle, 2001). Conceptual group 1 (CG1) is presented by the Ballistic “Single stage to orbit” (SSTO) reusable vehicle. All vehicles which use classical rocketry scheme of the propulsion trajectory are called “Ballistic” i.e. the ballistic vehicle is lifted to orbit under the impact of rocket engines thrust. CG1-vehicle is able to reach the low earth orbit (LEO) without stage separation reducing the number of required rocket engines. Technological feasibility of SSTO concepts is proven by numerous studies (Koelle, 2001). CG2 representatives are ballistic “Two stages to orbit” (TSTO) reusable vehicles. The difference between CG1 and CG2 consists in application of vacuum rocket engines in the second stage and, consequently, stage separation. CG2 are the most mass-effective vehicles. CG3 is presented by the winged SSTO vehicles with rocket propulsion by “Lifting body” aerodynamic scheme. Ascensional force is provided by the aerodynamic shape of the vehicle’s structure at high speeds. Winged TSTO vehicles with rocket propulsion and parallel or tandem staging form the CG4. The winged configuration provides wide landing capability for both stages. CG5 is presented by winged TSTO vehicles with airbreathing propulsion in the first stage and rocket-propelled second stage. Airbreathing jet engines provide high reusability ratio comparing with other concepts as well as the widest landing capability. Aerospace Plane with scramjet-rocket propulsion forms CG6. The vehicle is able to reach near-cosmic speed in rarefied layers of the atmosphere and then accelerate with rocket engines. The most ecologically important resemblance of represented concepts is reusability. This reduces space debris formation (due to lack of waste hardware). Reusable launch vehicles can also be used to return the spent satellites. Structural differences between the concepts form 3 criterions of comparison by ecological impact: 1) propellant toxicity; 2) safety of surface facilities (vehicle damage inside the atmosphere); 3) probability of space debris formation (vehicle damage outside the atmosphere). Comparison of the concepts by these criterions allows substantiating the most ecologically acceptable direction of research. Results of the comparison demonstrate that the most ecologically acceptable low-cost launch vehicle configuration is: Ballistic SSTO or TSTO reusable launch vehicle with “LOX+LH2” propellant. The results can be explained by following way: combustion products of the propellant “liquid oxygen + liquid hydrogen” are absolutely safe for environment. It also provides maximal performance of rocket engine (due to the highest specific impulse). Ballistic ascent scheme allows using relatively simple technologies and provides high reliability level. In combination with minimal time of atmospheric flight this provides high level of safety for surface facilities. These results may be used for substantiation of dominant research direction.

Technogeneous impact of rocket and space activities on the environment is one of the most actual problems of practical cosmonautics. This technogeneous impact is not only the pollution of near Earth space with space debris (worked-off stages of space launch vehicle (SLV)), but also the pollution of significant areas on the Earth surface with worked-off lower stages of SLV, which fall down after having accomplished their mission. In OmSTU and IPCP RAS it was suggested to apply different self-burning compositions, generating hot gases for the evaporation of the unused residues of liquid propellant in tanks of SLV. Then the mixture of the evaporated compounds together with the gaseous combustion products from gas-generating compositions is used as propellant mixture for the autonomous gas rocket engine. Such a solution would decrease considerably the level of the environment pollution and additionally it increases the energetic characteristics of SLV. For example, in the case of the second stage of SLV «Soyuz-2.1.v» it increases the total velocity by 5%. Also it is proposed to use firing the pyrotechnic compositions like (thermites) for the fairings heating up to the temperature when the fairing material can be ignited in air. It would reduce considerably the amount and the mass of the separating parts of SLV that fall to the Earth.

The paper presents the formulation of the mathematical problem for developing the rational telemetry message traffic via data-transmission channels. The source data region, required varying parameters, indicators and criteria of quality for the telemetry message traffic, and restrictions on the permissible solutions region were determined. The methodology for solving the set problem using the mathematical apparatus of sequential optimization is proposed. The developed methodology was tested using the source data and telemetric information recorded during launches of “conditionally light” spacecraft by the “Proton-M” launcher vehicle with the “Briz-M” upper stage from the Baikonur cosmodrome.

The choice is discussed of solid gas generating compositions for venting by hot combustion products a fuel tank of the spent orbital stage of a space launch vehicle with a main liquid rocket engine. Non explosiveness is achieved via eliminating the<br />possibility of freezing the drainage system when products of gasification (vapours of a propellant component + the remains of a gas boost + the hot products of combustion of solid gas generating compositions) are discharged from the tank into surrounding space. There are imposed requirements, constraints, and criteria for selecting solid gas generating compositions. When considering tank with the residues of liquid oxygen belonging to orbital spent stage of the launch vehicle «Zenith» the ways are shown how to ensure explosion safety, which on the basis of proposed approaches by selecting solid gas generating compositions (SGC) which generate oxygen and<br />nitrogen. As a criterion of choice of SGC the total mass of the gasification system is adopted, which includes the SGC mass for gasification of liquid propellant residues, the mass of the gas generator and the mass of system to supply the combustion products of SGC into the tank. It is proposed use of residual heat in the condensed phase of the SGC combustion products to heat up the drainage system, which will increase the probability of a trouble-free operation of the drainage system.

The application of thick-layer nickel (up to 700 μm) and chromium (up to 200 μm) coatings has been widely used to give the combustion chamber of a liquid-propellant rocket engine the required operational properties. The main parameter that determines the ability of a coating to fulfill its function is its thickness and uniformity of its distribution. The main problem of current nondestructive methods for determining the thickness of coatings under consideration is that they can be used only at the stage of production of rocket engineering products, when there is an access to the product from the side of the inner wall of the combustion chamber before and after applying a chromium coating to the nickel sublayer. However, when an already finished product arrives at subsequent stages of assembly to another enterprise, there is often a need of incoming control of the thicknesses of coatings from nickel and chromium. In this case, it is not possible to apply existing control techniques to a finished product, or the use of these techniques leads to unacceptable errors in the results of measurements. The goal of the research was to develop a technique for nondestructive determination of the thickness of each component of the two-layer nickel-chromium coating by the magnetic ponderomotive method under conditions of unilateral access to the finished product from the side of the chromium coating.A new technique for nondestructive determination of the thicknesses of nickel and chromium coatings of the double-layer structure on a finished product without a priori data on the properties or thicknesses of these coatings or a product in general is proposed using a magnetic ponderomotive method.This newly developed technique is implemented in the thickness gauge TEP-XN1 of double-layer nickel- chromium coatings, which is successfully used by enterprises of the rocket and space industry of the Russian Federation.

Abstract. The main and upper stages of heavy lift launchers for space applications are often fuelled by cryogenic liquids. In order to enable the re-ignition of a cryogenic upper stage for orbital changes, it is crucial to study the behaviour of these fluids in microgravity. As gaseous bubbles entering the fuel lines of the engine can cause the destruction of the engine, these bubbles are a risk for the functionality of the re-ignition mode. To measure an evolving gaseous phase and its volume, a capacitive measurement system for two-phase mixtures was realised. Its electrodes are arranged in such a way that phase changes inside a vessel can be detected without parasitic heating under cryogenic conditions. Two cases have been investigated: a fill-level measurement involving a large gas bubble above a homogenous liquid on the one hand, and the identification of a bubble stream inside a liquid on the other hand. The system concept was tested in a cryogenic environment allowing the controlled generation of bubble streams inside liquid nitrogen and of a contiguous gaseous volume above the liquid. The characteristics of the measurable capacitances of different pairs of electrodes were experimentally determined and compared with finite-element simulations (Ansys). In addition, the electrical flux density was computed to corroborate the simulated capacitance curves with theoretical statements. The experimental findings closely agree with the simulated results if possible disturbances due to the characteristics of the capacitance measurement hardware are properly taken into account. Thus, by measuring various capacitances, it was possible to determine the level up to which a receptacle inside a liquid-nitrogen tank was filled with liquid (the space above the liquid being taken up by gaseous nitrogen), to identify the existence of a bubble stream in the liquid nitrogen and to demonstrate that the capacitance measurement results enable one to differentiate between the two cases.

Hot section components in high-performance aircraft and rocket engines are increasingly being made of single crystal nickel superalloys such as PWA1480, PWA1484, CMSX-4, and Rene N-4 as these materials provide superior creep, stress rupture, melt resistance, and thermomechanical fatigue capabilities over their polycrystalline counterparts. Fatigue failures in PWA1480 single crystal nickel-base superalloy turbine blades used in the space shuttle main engine fuel turbopump are discussed. During testing many turbine blades experienced stage II noncrystallographic fatigue cracks with multiple origins at the core leading edge radius and extending down the airfoil span along the core surface. The longer cracks transitioned from stage II fatigue to crystallographic stage I fatigue propagation, on octahedral planes. An investigation of crack depths on the population of blades as a function of secondary crystallographic orientation (β) revealed that for β=45+/−15 deg tip cracks arrested after some growth or did not initiate at all. Finite element analysis of stress response at the blade tip, as a function of primary and secondary crystal orientation, revealed that there are preferential β orientations for which crack growth is minimized at the blade tip. To assess blade fatigue life and durability extensive testing of uniaxial single crystal specimens with different orientations has been tested over a wide temperature range in air and hydrogen. A detailed analysis of the experimentally determined low cycle fatigue properties for PWA1480 and SC 7-14-6 single crystal materials as a function of specimen crystallographic orientation is presented at high temperature (75°F–1800°F) in high-pressure hydrogen and air. Fatigue failure parameters are investigated for low cycle fatigue data of single crystal material based on the shear stress amplitudes on the 24 octahedral and 6 cube slip systems for FCC single crystals. The max shear stress amplitude [Δτmax] on the slip planes reduces the scatter in the low cycle fatigue data and is found to be a good fatigue damage parameter, especially at elevated temperatures. The parameter Δτmax did not characterize the room temperature low cycle fatigue data in high-pressure hydrogen well because of the noncrystallographic eutectic failure mechanism activated by hydrogen at room temperature. Fatigue life equations are developed for various temperature ranges and environmental conditions based on power-law curve fits of the failure parameter with low cycle fatigue test data. These curve fits can be used for assessing blade fatigue life.

The paper presents results of engineering studies and research and development efforts at RSC Energia to analyze and prove the feasibility of using the mass-produced oxygen-hydrocarbon engine 11D58M with 8.5 ton-force thrust as a basis for development of a high-performance multifunctional rocket engine with oxygen cooling and 5 ton-force thrust, which is optimal for upper stages (US), embodying a system that does not include a gas generator. The multi-functionality of the engine implies including in it additional units supporting some functions that are important for US, such as feeding propellant from US tanks to the engine after flying in zero gravity, autonomous control of the engine automatic equipment to support its firing, shutdown, adjustments during burn and emergency protection in case of off-nominal operation, as well as generating torques for controlling the US attitude and stabilizing it during coasting, etc. Replacing conventional engine chamber cooling that uses high-boiling hydrocarbon fuel with the innovative oxygen cooling makes it possible to get rid of the internal film cooling circuits and eliminate their attendant losses of fuel, while the use of the oxygen gasified in the cooling circuit of the chamber to drive the turbo pump assembly permits to design an engine that does not have a gas generator. Key words: Multifunctional rocket engine, oxygen cooling, gas-generatorless design, upper stage.

AbstractA computational tool able to perform a fast analysis of hybrid rocket engines is presented, describing briefly the mathematical and physical models used. Validation of the code is also shown: 16 different static firing tests available in the open literature are used to compare measured operational parameters such as chamber pressure, thrust, and specific impulse with the code’s output. The purpose of the program is to perform rapid evaluation and assessment on a possible first design of hybrid rockets, without relying on computationally expensive simulations or onerous experimental tests. The validated program considers as benchmark and study case the design of a liquid-oxygen/paraffin hybrid rocket engine to be used as the upper stage of a small launcher derived from VEGA building blocks. A full-factorial parametric analysis is performed for both pressure-fed and pump-fed systems to find a configuration that delivers the equivalent total impulse of a VEGA-like launcher third and fourth stage as a first evaluation. This parametric analysis is also useful to highlight how the oxidizer injection system, the fuel grain design, and the nozzle features affect the performance of the rocket.

The paper considers the process of removing a passive object by an active spacecraft, consisting of three stages: harpooning the object, deploying the tether, and towing. The shock pulse from the harpoon is used to reduce the angular velocity of the object and transfer it to the towing state. An algorithm for determining the position of the capture point on the object surface is proposed. The equations of relative motion of the transfer vehicle at the stage of tether deployment are given in the dimensionless form, which allows studying the movement in any parameter space. The law of thrust control at the stage of cable deployment is proposed and optimal control parameters that ensure safe towing are determined. The limits of applicability of the considered control law are found taking into account the structural and strength limitations of the system. As an example of using the proposed approach, a numerical simulation of withdrawing the Ariane 4 rocket upper stage was performed.

Rocket-based combined-cycle (RBCC) powered vehicles have been widely recognized as the most promising aircraft solution that could dramatically reduce the cost of space transportation. Researchers and scientists worldwide have conducted considerable overall design researches to cope with the challenges in RBCC development including mode transition, thermal protection and thrust enhancement. According to the way to orbit and the configuration characteristics, the hypersonic aircraft powered by RBCC engine are classified as four categories: single-stage-to-orbit (SSTO) two-dimensional configuration, SSTO axisymmetric configuration, two-stage-to-orbit (TSTO) two-dimensional configuration, and TSTO axisymmetric configuration. This paper systematically presents the development of the conceptual design of RBCC-powered vehicles. Both the structural and operating key parameters like the weight distribution, the RBCC propulsion performance and take-off mode, et al. are introduced in detail. On this basis, a comparative analysis of the advantages and disadvantages of the orbit model, the configuration selection and takeoff modes are conducted. In addition, the application prospect and technology development direction for hypersonic aircraft are also discussed. At the same time, the lessons that can be drew from previous hypersonic vehicle concept design are explored.

A new procedure is created for the calculation of heat and mass transfer processes in a cryogenic rocket tank. This simplified method is based on the assumption about homogeneity of temperature in liquid and vapor phase of a fuel component. This assumption made this model useful for such regime as refueling, self-pressurization, pressurization during engine working and other. As the example of method applicability, some calculation is made for refueling of KVTK upper stage to estimate component losses. For the self-pressurization regime, the results of the calculation is compared with experimental data for one cylindrical and one spherical hydrogen tanks. This comparison is shown that pressure rise rate in a full tank several times upper than in the calculations. But for the low level of liquid hydrogen the accuracy of this method is significantly increased. As the result, this procedure is recommended as a lover score of pressure rise during self-pressurization. Key words: cryogenic propellant tank, cryogenic fuel storage, cryogenic tank processes, mathematical modelling, calculation method, refueling, mass-average temperature.

Abstract At the Altitude Test Facility (ATF) of the University of Stuttgart, a linear compressor cascade test rig serves the investigation of ice crystal icing (ICI) under engine realistic conditions. A numerical model of the first stage of National Aeronautics and Space Administration (NASA) Stage 67 is validated with experimental data taken from the literature and used to investigate the respective ice crystal icing conditions for prospective cascade experiments. Eleven operating points simulating climb conditions with constant non-dimensional power setting through ascending parcels of moist air are selected for analysis. Only the melting-dominated regime is considered. The three-dimensional flow field is obtained using a Reynolds-averaged Navier–Stokes (RANS) approach in combination with a Spalart–Allmaras one-equation turbulence model. The droplet and ice crystal trajectories are calculated based on an Eulerian framework. The computation of the surface energy balance is adapted from the Messinger model taking into account unsteady phenomena. Four of 11 selected operating points indicate the onset of substantial ice accretion. A static wet-bulb temperature of freezing constitutes in general the lower icing limit for rig experiments. The upper icing limit depends on the ice water content impinging and sticking to the target surface.

Abstract We have extended our previous work to use the Murchison widefield array (MWA) as a non-coherent passive radar system in the FM frequency band, using terrestrial FM transmitters to illuminate objects in low Earth orbit (LEO) and the MWA as the sensitive receiving element for the radar return. We have implemented a blind detection algorithm that searches for these reflected signals in difference images constructed using standard interferometric imaging techniques. From a large-scale survey using 20 h of archived MWA observations, we detect 74 unique objects over multiple passes, demonstrating the MWA to be a valuable addition to the global Space Domain Awareness network. We detected objects with ranges up to 977 km and as small as $0.03$ ${\rm m}^2$ radar cross section. We found that 30 objects were either non-operational satellites or upper-stage rocket body debris. Additionally, we also detected FM reflections from Geminid meteors and aircraft flying over the MWA. Most of the detections of objects in LEO were found to lie within the parameter space predicted by previous feasibility studies, verifying the performance of the MWA for this application. We have also used our survey to characterise these reflected signals from LEO objects as a source of radio frequency interference (RFI) that corrupts astronomical observations. This has allowed us to undertake an initial analysis of the impact of this RFI on the MWA and the future square kilometer array (SKA). As part of this analysis, we show that the standard MWA RFI flagging strategy misses most of this RFI and that this should be a careful consideration for the SKA.

In a media saturated world, doodles have recently received the kind of attention usually reserved for coverage of racy extra marital affairs, corrupt governance, and product malfunction. Former British Prime Minister Blair’s private doodling at a World Economic Forum meeting in 2005 raised suspicions that he, according to one keen graphologist, struggled “to maintain control in a confusing world," which infers he was attempting to cohere a scattershot, fragmentary series of events (Spiegel). However, placid-faced Microsoft CEO Bill Gates, who sat nearby, actually scrawled the doodles. In this case, perhaps the scrawls mimicked the ambience in the room: Gates might have been ‘tuning’–registering the ‘white noise’ of the participants, letting his unconscious dictate doodles as a way to cope with the dissonance trekking in with the officialspeak. The doodles may have documented and registered the space between words, acting like deposits from his gestalt.Sometimes the most intriguing doodles co-exist with printed texts. This includes common vernacular graffiti that lines public and private books and magazines. Such graffiti exposes tensions in the role of readers as well as horror vacui: a fear of unused, empty space. Yet, school children fingering fresh pages and stiff book spines for the first few times often consider their book pages as sanctioned, discreet, and inviolable. The book is an object of financial and cultural investment, or imbued both with mystique and ideologies. Yet, in the e-book era, the old-fashioned, physical page is a relic of sorts, a holdover from coarse papyrus culled from wetland sage, linking us to the First Dynasty in Egypt. Some might consider the page as a vessel for typography, a mere framing device for text. The margins may reflect a perimeter of nothingness, an invisible borderland that doodles render visible by inhabiting them. Perhaps the margins are a bare landscape, like unmarred flat sand in a black and white panchromatic photo with unique tonal signature and distinct grain. Perhaps the margins are a mute locality, a space where words have evaporated, or a yet-to-be-explored environment, or an ambient field. Then comes the doodle, an icon of vernacular art.As a modern folklorist, I have studied and explored vernacular art at length, especially forms that may challenge and fissure aesthetic, cultural, and social mores, even within my own field. For instance, I contend that Grandma Prisbrey’s “Bottle Village,” featuring millions of artfully arranged pencils, bottles, and dolls culled from dumps in Southern California, is a syncretic culturescape with underlying feminist symbolism, not merely the product of trauma and hoarding (Ensminger). Recently, I flew to Oregon to deliver a paper on Mexican-American gravesite traditions. In a quest for increased multicultural tolerance, I argued that inexpensive dimestore objects left on Catholic immigrant graves do not represent a messy landscape of trinkets but unique spiritual environments with links to customs 3,000 years old. For me, doodles represent a variation on graffiti-style art with cultural antecedents stretching back throughout history, ranging from ancient scrawls on Greek ruins to contemporary park benches (with chiseled names, dates, and symbols), public bathroom latrinalia, and spray can aerosol art, including ‘bombing’ and ‘tagging’ hailed as “Spectacular Vernaculars” by Russell Potter (1995). Noted folklorist Alan Dundes mused on the meaning of latrinalia in Here I Sit – A Study of American Latrinalia (1966), which has inspired pop culture books and web pages for the preservation and discussion of such art (see for instance, www.itsallinthehead.com/gallery1.html). Older texts such as Classic American Graffiti by Allen Walker Read (1935), originally intended for “students of linguistics, folk-lore, abnormal psychology,” reveal the field’s longstanding interest in marginal, crude, and profane graffiti.Yet, to my knowledge, a monograph on doodles has yet to be published by a folklorist, perhaps because the art form is reconsidered too idiosyncratic, too private, the difference between jots and doodles too blurry for a taxonomy and not the domain of identifiable folk groups. In addition, the doodles in texts often remain hidden until single readers encounter them. No broad public interaction is likely, unless a library text circulates freely, which may not occur after doodles are discovered. In essence, the books become tainted, infected goods. Whereas latrinalia speaks openly and irreverently, doodles feature a different scale and audience.Doodles in texts may represent a kind of speaking from the ‘margin’s margins,’ revealing the reader-cum-writer’s idiosyncratic, self-meaningful, and stylised hieroglyphics from the ambient margins of one’s consciousness set forth in the ambient margins of the page. The original page itself is an ambient territory that allows the meaning of the text to take effect. When those liminal spaces (both between and betwixt, in which the rules of page format, design, style, and typography are abandoned) are altered by the presence of doodles, the formerly blank, surplus, and soft spaces of the page offer messages coterminous with the text, often allowing readers to speak, however haphazardly and unconsciously, with and against the triggering text. The bleached whiteness can become a crowded milieu in the hands of a reader re-scripting the ambient territory. If the book is borrowed, then the margins are also an intimate negotiation with shared or public space. The cryptic residue of the doodler now resides, waiting, for the city of eyes.Throughout history, both admired artists and Presidents regularly doodled. Famed Italian Renaissance painter Filippo Lippi avoided strenuous studying by doodling in his books (Van Cleave 44). Both sides of the American political spectrum have produced plentiful inky depictions as well: roughshod Democratic President Johnson drew flags and pagodas; former Hollywood fantasy fulfiller turned politician Republican President Reagan’s specialty was western themes, recalling tropes both from his actor period and his duration acting as President; meanwhile, former law student turned current President, Barack Obama, has sketched members of Congress and the Senate for charity auctions. These doodles are rich fodder for both psychologists and cross-discipline analysts that propose theories regarding the automatic writing and self-styled miniature pictures of civic leaders. Doodles allow graphologists to navigate and determine the internal, cognitive fabric of the maker. To critics, they exist as mere trifles and offer nothing more than an iota of insight; doodles are not uncanny offerings from the recesses of memory, like bite-sized Rorschach tests, but simply sloppy scrawls of the bored.Ambient music theory may shed some light. Timothy Morton argues that Brian Eno designed to make music that evoked “space whose quality had become minimally significant” and “deconstruct the opposition … between figure and ground.” In fact, doodles may yield the same attributes as well. After a doodle is inserted into texts, the typography loses its primacy. There is a merging of the horizons. The text of the author can conflate with the text of the reader in an uneasy dance of meaning: the page becomes an interface revealing a landscape of signs and symbols with multiple intelligences–one manufactured and condoned, the other vernacular and unsanctioned. A fixed end or beginning between the two no longer exists. The ambient space allows potential energies to hover at the edge, ready to illustrate a tension zone and occupy the page. The blank spaces keep inviting responses. An emergent discourse is always in waiting, always threatening to overspill the text’s intended meaning. In fact, the doodles may carry more weight than the intended text: the hierarchy between authorship and readership may topple.Resistant reading may take shape during these bouts. The doodle is an invasion and signals the geography of disruption, even when innocuous. It is a leveling tool. As doodlers place it alongside official discourse, they move away from positions of passivity, being mere consumers, and claim their own autonomy and agency. The space becomes co-determinant as boundaries are blurred. The destiny of the original text’s meaning is deferred. The habitus of the reader becomes embodied in the scrawl, and the next reader must negotiate and navigate the cultural capital of this new author. As such, the doodle constitutes an alternative authority and economy of meaning within the text.Recent studies indicate doodling, often regarded as behavior that announces a person’s boredom and withdrawal, is actually a very special tool to prevent memory loss. Jackie Andrade, an expert from the School of Psychology at the University of Plymouth, maintains that doodling actually “offsets the effects of selective memory blockade,” which yields a surprising result (quoted in “Doodling Gets”). Doodlers exhibit 29% more memory recall than those who passively listen, frozen in an unequal bond with the speaker/lecturer. Students that doodle actually retain more information and are likely more productive due to their active listening. They adeptly absorb information while students who stare patiently or daydream falter.Furthermore, in a 2006 paper, Andrew Kear argues that “doodling is a way in which students, consciously or not, stake a claim of personal agency and challenge some the values inherent in the education system” (2). As a teacher concerned with the engagement of students, he asked for three classes to submit their doodles. Letting them submit any two-dimensional graphic or text made during a class (even if made from body fluid), he soon discovered examples of “acts of resistance” in “student-initiated effort[s] to carve out a sense of place within the educational institution” (6). Not simply an ennui-prone teenager or a proto-surrealist trying to render some automatic writing from the fringes of cognition, a student doodling may represent contested space both in terms of the page itself and the ambience of the environment. The doodle indicates tension, and according to Kear, reflects students reclaiming “their own self-recognized voice” (6).In a widely referenced 1966 article (known as the “doodle” article) intended to describe the paragraph organisational styles of different cultures, Robert Kaplan used five doodles to investigate a writer’s thought patterns, which are rooted in cultural values. Now considered rather problematic by some critics after being adopted by educators for teacher-training materials, Kaplan’s doodles-as-models suggest, “English speakers develop their ideas in a linear, hierarchal fashion and ‘Orientals’ in a non-liner, spiral fashion…” (Severino 45). In turn, when used as pedagogical tools, these graphics, intentionally or not, may lead an “ethnocentric, assimilationist stance” (45). In this case, doodles likely shape the discourse of English as Second Language instruction. Doodles also represent a unique kind of “finger trace,” not unlike prints from the tips of a person’s fingers and snowflakes. Such symbol systems might be used for “a means of lightweight authentication,” according to Christopher Varenhorst of MIT (1). Doodles, he posits, can be used as “passdoodles"–a means by which a program can “quickly identify users.” They are singular expressions that are quirky and hard to duplicate; thus, doodles could serve as substitute methods of verifying people who desire devices that can safeguard their privacy without users having to rely on an ever-increasing number of passwords. Doodles may represent one such key. For many years, psychologists and psychiatrists have used doodles as therapeutic tools in their treatment of children that have endured hardship, ailments, and assault. They may indicate conditions, explain various symptoms and pathologies, and reveal patterns that otherwise may go unnoticed. For instance, doodles may “reflect a specific physical illness and point to family stress, accidents, difficult sibling relationships, and trauma” (Lowe 307). Lowe reports that children who create a doodle featuring their own caricature on the far side of the page, distant from an image of parent figures on the same page, may be experiencing detachment, while the portrayal of a father figure with “jagged teeth” may indicate a menace. What may be difficult to investigate in a doctor’s office conversation or clinical overview may, in fact, be gleaned from “the evaluation of a child’s spontaneous doodle” (307). So, if children are suffering physically or psychologically and unable to express themselves in a fully conscious and articulate way, doodles may reveal their “self-concept” and how they feel about their bodies; therefore, such creative and descriptive inroads are important diagnostic tools (307). Austrian born researcher Erich Guttman and his cohort Walter MacLay both pioneered art therapy in England during the mid-twentieth century. They posited doodles might offer some insight into the condition of schizophrenics. Guttman was intrigued by both the paintings associated with the Surrealist movement and the pioneering, much-debated work of Sigmund Freud too. Although Guttman mostly studied professionally trained artists who suffered from delusions and other conditions, he also collected a variety of art from patients, including those undergoing mescaline therapy, which alters a person’s consciousness. In a stroke of luck, they were able to convince a newspaper editor at the Evening Standard to provide them over 9,000 doodles that were provided by readers for a contest, each coded with the person’s name, age, and occupation. This invaluable data let the academicians compare the work of those hospitalised with the larger population. Their results, released in 1938, contain several key declarations and remain significant contributions to the field. Subsequently, Francis Reitman recounted them in his own book Psychotic Art: Doodles “release the censor of the conscious mind,” allowing a person to “relax, which to creative people was indispensable to production.”No appropriate descriptive terminology could be agreed upon.“Doodles are not communications,” for the meaning is only apparent when analysed individually.Doodles are “self-meaningful.” (37) Doodles, the authors also established, could be divided into this taxonomy: “stereotypy, ornamental details, movements, figures, faces and animals” or those “depicting scenes, medley, and mixtures” (37). The authors also noted that practitioners from the Jungian school of psychology often used “spontaneously produced drawings” that were quite “doodle-like in nature” in their own discussions (37). As a modern folklorist, I venture that doodles offer rich potential for our discipline as well. At this stage, I am offering a series of dictums, especially in regards to doodles that are commonly found adjacent to text in books and magazines, notebooks and journals, that may be expanded upon and investigated further. Doodles allow the reader to repopulate the text with ideogram-like expressions that are highly personalised, even inscrutable, like ambient sounds.Doodles re-purpose the text. The text no longer is unidirectional. The text becomes a point of convergence between writer and reader. The doodling allows for such a conversation, bilateral flow, or “talking back” to the text.Doodles reveal a secret language–informal codes that hearken back to the “lively, spontaneous, and charged with feeling” works of child art or naïve art that Victor Sanua discusses as being replaced in a child’s later years by art that is “stilted, formal, and conforming” (62).Doodling animates blank margins, the dead space of the text adjacent to the script, making such places ripe for spontaneous, fertile, and exploratory markings.Doodling reveals a democratic, participatory ethos. No text is too sacred, no narrative too inviolable. Anything can be reworked by the intimate graffiti of the reader. The authority of the book is not fixed; readers negotiate and form a second intelligence imprinted over the top of the original text, blurring modes of power.Doodles reveal liminal moments. Since the reader in unmonitored, he or she can express thoughts that may be considered marginal or taboo by the next reader. The original subject of the book itself does not restrict the reader. Thus, within the margins of the page, a brief suspension of boundaries and borders, authority and power, occurs. The reader hides in anonymity, free to reroute the meaning of the book. Doodling may convey a reader’s infantalism. Every book can become a picture book. This art can be the route returning a reader to the ambience of childhood.Doodling may constitute Illuminated/Painted Texts in reverse, commemorating the significance of the object in hitherto unexpected forms and revealing the reader’s codex. William Blake adorned his own poems by illuminating the skin/page that held his living verse; common readers may do so too, in naïve, nomadic, and primitive forms. Doodling demarcates tension zones, yielding social-historical insights into eras while offering psychological glimpses and displaying aesthetic values of readers-cum-writers.Doodling reveals margins as inter-zones, replete with psychogeography. While the typography is sanctioned, legitimate, normalised, and official discourse (“chartered” and “manacled,” to hijack lines from William Blake), the margins are a vernacular depository, a terminus, allowing readers a sense of agency and autonomy. The doodled page becomes a visible reminder and signifier: all pages are potentially “contested” spaces. Whereas graffiti often allows a writer to hide anonymously in the light in a city besieged by multiple conflicting texts, doodles allow a reader-cum-writer’s imprint to live in the cocoon of a formerly fossilised text, waiting for the light. Upon being opened, the book, now a chimera, truly breathes. Further exploration and analysis should likely consider several issues. What truly constitutes and shapes the role of agent and reader? Is the reader an agent all the time, or only when offering resistant readings through doodles? How is a doodler’s agency mediated by the author or the format of texts in forms that I have to map? Lastly, if, as I have argued, the ambient space allows potential energies to hover at the edge, ready to illustrate a tension zone and occupy the page, what occurs in the age of digital or e-books? Will these platforms signal an age of acquiescence to manufactured products or signal era of vernacular responses, somehow hitched to html code and PDF file infiltration? Will bytes totally replace type soon in the future, shaping unforeseen actions by doodlers? Attached Figures Figure One presents the intimate graffiti of my grandfather, found in the 1907 edition of his McGuffey’s Eclectic Spelling Book. The depiction is simple, even crude, revealing a figure found on the adjacent page to Lesson 248, “Of Characters Used in Punctuation,” which lists the perfunctory functions of commas, semicolons, periods, and so forth. This doodle may offset the routine, rote, and rather humdrum memorisation of such grammatical tools. The smiling figure may embody and signify joy on an otherwise machine-made bare page, a space where my grandfather illustrated his desires (to lighten a mood, to ease dissatisfaction?). Historians Joe Austin and Michael Willard examine how youth have been historically left without legitimate spaces in which to live out their autonomy outside of adult surveillance. For instance, graffiti often found on walls and trains may reflect a sad reality: young people are pushed to appropriate “nomadic, temporary, abandoned, illegal, or otherwise unwatched spaces within the landscape” (14). Indeed, book graffiti, like the graffiti found on surfaces throughout cities, may offer youth a sense of appropriation, authorship, agency, and autonomy: they take the page of the book, commit their writing or illustration to the page, discover some freedom, and feel temporarily independent even while they are young and disempowered. Figure Two depicts the doodles of experimental filmmaker Jim Fetterley (Animal Charm productions) during his tenure as a student at the Art Institute of Chicago in the early 1990s. His two doodles flank the text of “Lady Lazarus” by Sylvia Plath, regarded by most readers as an autobiographical poem that addresses her own suicide attempts. The story of Lazarus is grounded in the Biblical story of John Lazarus of Bethany, who was resurrected from the dead. The poem also alludes to the Holocaust (“Nazi Lampshades”), the folklore surrounding cats (“And like the cat I have nine times to die”), and impending omens of death (“eye pits “ … “sour breath”). The lower doodle seems to signify a motorised tank-like machine, replete with a furnace or engine compartment on top that bellows smoke. Such ominous images, saturated with potential cartoon-like violence, may link to the World War II references in the poem. Meanwhile, the upper doodle seems to be curiously insect-like, and Fetterley’s name can be found within the illustration, just like Plath’s poem is self-reflexive and addresses her own plight. Most viewers might find the image a bit more lighthearted than the poem, a caricature of something biomorphic and surreal, but not very lethal. Again, perhaps this is a counter-message to the weight of the poem, a way to balance the mood and tone, or it may well represent the larval-like apparition that haunts the very thoughts of Plath in the poem: the impending disease of her mind, as understood by the wary reader.

She's the dollars, she's my protection; she's a promise, in the year of election. Sister, I can't let you go; I'm like a preacher, stealing hearts at a traveling show. For love or money, money, money... Desire -- U2, "Desire" (1988) For the love of money. In the worship of things. Desire has traditionally been employed by advertising as a means of selling product. Regardless of culture, more powerful than context, desire is invoked as one of capitalism's iron-clad codes of quality. The Uses of Desire in Advertising Specifically, two variants have been most common. That in which desire is: (1) stimulated or (2) sated by a product. Crucial to advertisers, in both cases the product is more powerful than the thing the audience finds most powerful: the physical surge, the emotional rush, the chemical compulsion we label "desire". In the case of the former, a typical approach has been to create an equation in which product intervenes in the relationship between man and woman (and it is always man and woman), stimulating the psycho-physiological desire of one for the other. A classic pre-post design. Absent the product, desire would not arise, ad text often alleges. This tack is well captured in this ad for a perfume. Implicit in this approach is the assumption that the ad reader will desire desire. If so, he or she -- equally desirous of this turn of events -- will insert him or herself into the scenario, engaging in a symbolic, if not actual purchase of the product1. As we saw above, desire is often depicted via substitute symbols -- flashing red neon, burning matches, flame-blowers, stifling heat and raging brush fires2. The product is then used to extinguish such signs -- metaphorically quenching desire. This is the satiation variant identified at the outset. Standardised Desire? This last is an Australian ad, but in a wide variety of contexts, the same formula of product/desire appears. A recent Malaysian ad, for instance, plays out like this: a motorbike roars up to a doorstep; its leather-clad rider dismounts. Removing the helmet we find beneath a ... beautiful long-haired woman. Cut to a medium shot of the front door opening. A similarly-clad male leans against the molding. Rugged, firm, slightly aloof. Cut to product name: Dashing for Men. Followed by a picture of the cologne. "The Dashing Sensation" is then posted -- ripe with the implication that the cologne has worked its magical, magnetic attraction uniting female and male. It should be pointed out that Malaysia is a market with a significant western presence. Its top advertising firms are American, British and Italian. Thus, if one were curious as to whether desire was inherently a "cultural universal" or rather due to accession (i.e. the movement of intellectual and corporate capital), Euro-American presence would certainly be a factor to consider 3. Innovating Desire Bringing us to Japan. Desire is also a major theme there, as well. However, there, Japanese firms dominate ad production. And, interestingly, though the above-mentioned formulations do appear, desire in Japan also has its own specialised discourse. Rather than a relationship between the consumable and the consumer's emotional/physical state, discourse about desire can transpire independent of the product. Desire is often simply about desire. This is in keeping with a trend (or, more formally, a stage) of development Japanese advertising has achieved -- what I call "product-least advertising"; a condition in which discourse is about many things other than consumption. One of these things being desire. In closing I will wonder what this might say about Japanese society. Japanese Approaches to Desire As noted above, it is not the case that messages of product-induced desire do not appear in Japan. They are certainly more pervasive than in their Islamic neighbor, Malaysia. And, like America, desire is treated in an array of ways. Object-Mediated Desire One approach, admittedly less conventional, posits the product as medium. Only through the product will desire be manifested. In this ad, though verbal substitutes are invoked -- "lust", "love", "lick", "pinch", bite", "touch" -- desire is the guiding force as the figures trapped inside the product's bar code move mechanically toward physical consummation. Of particular note is the product's multi-faceted relationship to desire: it subsumes desire, stimulates it, provides a forum and means for its expression, and is the device securing its culmination ... the ad text is ambiguous as to which is controlling. This is a definitive "postmodern ad", pregnant with shifting perspective, situational action, oppositional signs and interpretive possibilities. The kind of text so-called "cultural studies" intends by the term "polysemy" (the notion that multiple meanings are contained in any sign -- see Fiske). In the case of desire, postmodern ads tell us not that desire is multiple. Rather, it is a singular (i.e. universally experienced) condition which may be differentially manifested and variously interpretable vis-à-vis singular object/products. Object-Induced Desire For instance, in this ad, again for instant noodles, two salarymen contemplate the statement "this summer's new product is stimulating". Each conjures a different image of just what "stimulating" means. For the younger man, a veritable deluge of sexual adoration; for his elder, an assault by a gang of femmes toughs. And while the latter man's fantasy would not qualify as the conventional definition of "desire", the former would. Thus, despite its polysemic trappings, the ad varies little from the standard approach outlined at the outset (plates 1 and 2). It posits that the product possesses sufficient power to stimulate desire for its consumer in external, unrelated others. Object-Directed Desire One of sociology's earliest complaints about capitalism was its reduction of people to the status of things. Social relations became instrumental acts aimed at achieving rational ends; the personalities, thoughts and qualities of those human agents engaged in the exchange become secondary to the sought good. Advertising, according to early semiotic critiques (see for instance Williamson), has only intensified this predilection, though in a different way. Ads instrumentalise by creating equality between the product presented and the person doing the presenting. When the presenter and product are conflated -- as in the case where a major star clasps the product to her bosom and addresses the camera with: "it's my Nice Once" (the product name) -- the objectification of the human subject may be unavoidable. The material and corporeal meld. She cherishes the drink. If we desire her (her status, her style, her actual physical being) but are realistic (and thus willing to settle for a substitute) ... we can settle for the simulation (her drink). This kind of vicarious taking, this symbolic sharing is common in advertising. Played out over and over the audience quickly learns to draw an equal sign between the two depicted objects (product and star). Purchasing one enables us to realise our desire (however incompletely) for the other. Sometimes the product and person are separated, but in a way that the discourse is about longing. The product is consumed because the human can't be -- perhaps a less satisfactory substitute, but a replacement, nonetheless. Or, as in the ad below, the two might be interchangeable. Interior. Bright yellow room without any discernible features. No walls, windows or furniture. Tight shot of black fishnet stockings, barely covered by a yellow dress. The legs swivel in a chair, allowing a fleeting shot of the model's crotch. Cut to a darkened interior. The product sits next to a set of wrenches. Cut back to first interior. Medium tight of the model's bare shoulders. She spins in her chair. Cut to the mechanic working on the engine of a car. Female voiceover: "Hey! Work AGAIN? ... Let's play!" Cut to tight shot of her pursed lips. "Hey! ... let's go for a drive", accompanying consecutive shots of the mechanic wiping sweat from his brow and the vamp's derriere. Next, a sequence of fast, tight images: mechanic revving the engine, the model's face, then her upper body viewed through heavily-ventilated apparel. "Oh", she says, "cars are cuter, huh?" The mechanic pauses to consider. Walks over to the product, pops the top. "When it comes to that sort of man..." her VO says as he gulps the drink, "women are suckers". Tight on woman's face: "(he's a) rake", she pouts. To better appreciate this endemic correspondence between objectification and desire, consider this ad for a car named "Rosso" ("red" in Italian, "aka" in Japanese). The model, "Anna", is tinted head to toe in red (red, of course, being the universal signifier for passion and desire)4. She and/or the car rouse enough passion in a male by-stander to literally make his blood boil. This, in turn, produces steam which, in turn, sends air current of sufficient force to propel Anna's skirt skyward. This, in turn, converts the man's face into an embarrassed and/or impassioned red. "Rosso!" he gushes enthusiastically -- reference to car, his condition, Anna and, presumably, her panties5. Thus, the desire for things -- people included -- is by no means disappearing in Japanese advertising. The name of the game is still to sell that which has been produced. Although Japanese ads have moved toward a decentring of product -- an introduction of consumption-least discourse, with a concomitant increase in popular cultural and societal content -- the great majority still speak in the language of "here it is, buy it!" The prevailing tenor is still object-oriented. And the spill-over, as we just saw, is a tendency to depict humans and their interactions in objectified terms. A recent ad, for the discount store LLAOX, is rather stark in this regard. A young man displays photos of the many items (guitars, television, appliances) he found at LLAOX. In the final shot, of an attractive woman standing in front of the items, he proudly boasts: "I found her at LLAOX, too!" Subject-Oriented Desire Like ads in other countries, then, Japanese ads tend to place the object ahead of the subject. Desire for the person depicted in the ad is either ancillary to the desire expressed for the product, or else exists as a function of the subject's objectified status. However, an accreting number of Japanese ads have begun orienting desire toward one or both of the subjects in the ad, over or independent of the object for sale. A man and woman in their early thirties sit at a table sipping whiskey. The woman leans toward the man and in a perky voice utters: "Hey, let's turn in soon." The man protests, pointing to the drink: "we haven't finished this, yet." The woman tilts her head. She insists "let's head home." Then in a conspiratorial undertone "it's that day" and winks. The man's elbow falls off the tabletop. The woman blows him a kiss. Cut to a cat hiding beneath one of his paws in embarrassment. (Source: Nikka All Malt Whiskey -- Japan, 1993) Admittedly, not all ad discourse involves desire. But of late considerable ad space has been devoted to human relations and longing6. Consider this promo for a health drink. A man stands on his verandah in his t-shirt and pyjama bottoms. He looks groggy. Cut to a young woman watering her plants on the adjacent porch. "Hey!" she coos to her bushes, "are you lively?" She tends the pots along the centre divider. Is she addressing her foliage or the young man on the other side? He cranes his neck to steal a peek. She seems unaware. He lays his head on his forearms, admiring her. Cut to a shot of her regarding the product; drinking it; savouring the taste. The text reads: "With Lactia you will bloom beautifully." The woman enthuses audibly: "happiness!" Her voyeur, still in thrall, emits a sigh, suddenly straightens and declares aloud (in English): "Nice!" The previous two examples feature desire by adults. Considerable contemporary desire-centred discourse, however, focuses on teens. In these cases the product is sometimes introduced as a symbol for desire -- as in this case of a potato chip which snaps crisply each time a boy's romantic advance is repelled. A boy and girl walk along a boardwalk. The boy tentatively reaches for his partner's hand. Just then an approaching bicyclist toots his horn and cleaves a path between the two. A superimposed chip snaps. Next, seated on the shoreline, the boy reaches out again. Suddenly, a wind-blown ball rolls past, prompting his intended to abruptly vacate her position. He is left, literally clutching air. Another chip snaps again. The boy reaches out to touch the girl's handprint in the sand. He utters "I like you". The girl turns and asks "what did you say?" He impotently shrugs "nothing at all." Cut to a box of the chips. This youthful obsession with desire plays prominently in ads. First, because it fits well with the "mini-drama" format currently favoured in Japanese advertising. Second, because it is an effective technique for capturing viewer interest. The emotional tugs keep the audience attending to the ad beyond the first viewing. In the following ad, while desire for the product is the punch line, the entire ad is structured around unrequited desire. The confusion of the former for the latter not only redounds to product value, but predisposes the audience toward empathy and engagement. A teenage girl in her plaid uniform steers her bike into its berth outside school. Her voiceover identifies the bike name, shows how one touch locks the wheel in place and the seat in the vertical position. "Oh!" a quavering male voice utters off camera. "Can I ask name?" Japanese being a language that often operates without articles and pronouns, we aren't sure which name he means. Quick zoom in on the girl's expectant expression. "Eh?" she asks breathlessly. Her narration stops, her heart soars, glowing a vibrant red over her white sweater. "The bike's name", her interlocutor clarifies. All at once, the throbbing red heart is extinguished, fading to a black circular smudge. Her expectant smile dissolves into disappointment. Not all scenarios are downers, however. In the following case the product is a prop -- at best an accoutrement -- in the teenage game of expressing desire. A spry girl pours hot water into two cups. Off camera an older female voice asks whether she isn't supposed to be resting. "Don't worry about it", the girl replies. Cut to exterior shot. She's wearing a short coat, backing through the front door with the two cups in her hands. Cut to an angled reaction shot: a handsome boy leans across his bike, placing a letter in the post. He holds the letter up. "This", he says. Cut to the girl, now leaning against the entryway of the building, sipping her drink. Haltingly, in a breathy voice, she utters: "To... tomorrow... would have been... okay. But..." Japanese being the language of implication we read this as "it's fine the way it is working out." With the girl in the foreground, we see the boy leaning against the entryway on the opposite side contemplating his drink. Cut to a long angled shot from high above. The two teens sup in the cool evening air, alone, intimate, yet separated by the building's bright entrance. The narrator closes with a message about the nutritional value of the drink -- wholly unrelated to the unequivocal web of intimacy spun by these two youths. This ad offers us a perfect take on how desire is constructed and reproduced in contemporary ads in Japan. A perfect place for us to close. Evolving Desire? Desire is not new to advertising, but the form in which it is currently being expressed is. In Japan, at least, where commercials strive for polysemy in the volatile, evanescent and ultimately quixotic struggle for audience attention, communication is increasingly about things unrelated to the product. High on the list are affection, intimacy and sexuality -- aspects of human existence which bear considerable connection to desire. Reproduced in a variety of forms, played out in an array of contexts, by a variety of demographic "types", such commercial communications have the effect of centralising desire as a major theme in contemporary Japanese society7. The increase in so-called "secondary discourse"8 about human longing is palpable. But what to make of it? Clear explanations lie in "social evolution" -- factors such as: Japan's remarkable achievement of its postwar economic goals; its subsequent economic meltdown and accreting political malaise; the dramatic decline in corporate loyalty; disintegration of the family; increased urbanisation, atomisation and anomie; the stratification of generations and economic classes; increased materialism and attention to status; the concomitant loss of a personal raison d'être and collective moral beacon. In fact, all the reasons that Emile Durkheim diagnosed in fin de siècle France in inventing the discipline of sociology and Murakami Ryu has recently discerned a century later in fin de siècle Japan. Desire is a manifestation of social breakdown, as well as a plea for its resolution. As we enter a new century -- indeed a new millenium -- it is an empirical question worth monitoring whether the Japanese obsession with desire will continue to swell. Footnotes 1. Although the claims in this paper are qualitative, rather than quantitative, without question it is true that both men and women in Japanese television advertising are depicted as desiring. In this way, one could claim that desire exists independent of gender in ads. At the same time, it is almost certain that desire is often depicted as being manifested differentially by men and women. However, as one can infer from the data below, this is not always so (viz. "True Love"). Moreover, while women (or men) might more often fit one or another of the constructs below (i.e. object-mediated, object-induced, object-directed, subject-oriented) than their opposite number, cases can generally be found in which both (male and female) are depicted desiring in each of the stated relationships. 1. Thinking of this (fire-desire) symbol-set generally (and this ad specifically), one is reminded of the Springsteen lyric: At night I wake up with the sheets soaking wet and a freight train running through the middle of my head; Only you can cool my desire. I'm on fire. -- Bruce Springsteen: "I'm on Fire" (1984) Reminding one of the lyric by Shocking Blue from their decade-spanning Number 1 single (1970 by the Dutch band as well as the 1986 cover version by Bananarama): I'm your Venus, I'm your fire at your desire. If not the Earth, Wind and Fire phrasing from "That's the Way of the World" (1975): Hearts of fire, creates love desire... Of course, the fire/desire combo might also have become a universal association due to the easy opportunity (at least in English) to commit a rhyme (no matter how cloddish). 2. It has yet to be determined that desire is a cultural universal. However, the universal presence and relatively uniform logic of the "machinery of capitalism" (a major aspect of which is advertising) certainly serves as a powerful prod. That machinery overlaps culture and tends to act on it in relatively similar ways (one of which may just be the discourse about desire). This, of course, makes no claims about universal outcomes. I have addressed the interaction of capitalism and context and the themes of global/local, homogeneity/heterogeneity, universal/particular in a series of articles concerning information transfer, body, color, and advertising form in comparative context. Please see my home page for references to and greater detail on this work. 3. Regarding red as signifier, see Branston & Stafford (7). Also see my work on color universals ("The Color of Meaning") and culture-specific colour conventions ("The Color of Difference"). 4. Support for this interpretation can be found in other ads, as ideas and practices in Japanese advertising tend to travel in twos or threes. During this same period, Suzuki Move placed Leonardo DiCaprio behind the wheel. As he tooled around the city, his accelleration was such as to raise the skirts of two by-standers. DiCaprio promptly braked, placed the car in reverse, rolled astride the two women, and impishly pointing at each, identified the shade of underpants ("white and strawberry") they were sporting. 5. And let me reiterate: All such depictions are exclusively about sexual/emotional longing between men and women. 6. As I am mainly working with Japanese data in this article, I feel comfortable only seeking to draw conclusions about Japanese society. Certainly, one could fathom conducting the same sort of analysis and arriving at the same general conclusions about other postmodern, capitalist, commercial-centred, consumer-oriented societies. 7.
