Abstract:

In January 1990, a test of the feasibility of airborne gravimetry from a small geophysical survey aircraft, a Cessna 404, was conducted over the Long Island Sound using a Bell Aerospace BGM-3 sea gravity meter. Gravity has been measured from large aircraft and specially modified de Havilland Twin Otters but never from small, standard survey aircraft. The gravity field of the Long Island Sound is dominated by an asymmetric positive 30 mGal anomaly which is well constrained by both marine and land gravity measurements. Using a Trimble 4000 GPS receiver to record the aircraft’s horizontal position and radar altimeter elevations to recover the vertical accelerations, gravity anomalies along a total of 65 km were successfully measured. The root mean square (rms) difference between the airborne results and marine measurements within 2 km of the flight path was 2.6 mGal for 15 measured values. The anomalies recovered from airborne gravimetry can also be compared with the gridded regional free air gravity field calculated using all available marine and land gravity measurements. The rms difference between 458 airborne gravity measurements and the regional gravity field is 2.7 mGal. This preliminary experiment demonstrates that gravity anomalies, with wavelengths as short as 5 km, can be measured from small aircraft with accuracies of 2.7 mGal or better. The gravity measurements could be improved by higher quality vertical and horizontal positioning and tuning the gravimeter’s stabilized platform for aircraft use.

Abstract:

Abstract. A new aircraft-mounted probe for collecting samples of cloud water has been designed, fabricated, and extensively tested. Following previous designs, the probe uses inertial separation to remove cloud droplets from the airstream, which are subsequently collected and stored for offline analysis. We report details of the design, operation, and modelled and measured probe performance. Computational fluid dynamics (CFD) was used to understand the flow patterns around the complex interior geometrical features that were optimized to ensure efficient droplet capture. CFD simulations coupled with particle tracking and multiphase surface transport modelling provide detailed estimates of the probe performance across the entire range of flight operating conditions and sampling scenarios. Physical operation of the probe was tested on a Lockheed C-130 Hercules (fuselage mounted) and de Havilland Twin Otter (wing pylon mounted) during three airborne field campaigns. During C-130 flights on the final field campaign, the probe reflected the most developed version of the design and a median cloud water collection rate of 4.5 mL min−1 was achieved. This allowed samples to be collected over 1–2 min under optimal cloud conditions. Flights on the Twin Otter featured an inter-comparison of the new probe with a slotted-rod collector, which has an extensive airborne campaign legacy. Comparison of trace species concentrations showed good agreement between collection techniques, with absolute concentrations of most major ions agreeing within 30 %, over a range of several orders of magnitude.

Abstract:

Este estudo tem como objetivo avaliar cinco métodos de previsão para demanda intermitente usando uma série histórica de consumo de peças sobressalentes da aeronave 737 Next Generation, fabricado pela Boeing, da maior frota aérea brasileira gerenciada pela VRG Airline Company S/A. Os métodos de Winter, Croston, Single Exponential Smoothing, Weight Moving Average e Método de Distribuição de Poisson foram testados em um histórico de 53 peças sobressalentes e cada uma delas possui um histórico de demanda de trinta e seis meses (janeiro de 2013 a dezembro de 2015). Os resultados mostraram que os métodos Weight Moving Average, Distribuição de Poisson e Croston apresentaram os melhores ajustes. Além disso, observou-se que a maior parte das demandas por peças sobressalentes apresentaram um padrão smooth ao contrário do resultado obtido pelo estudo de Ghobbar and Friend (2003) que apresentou um padrão lumpy. Por outro lado, tem-se que o Método de Winter apresentou-se como o de pior ajuste em ambos os estudos. Conclui-se que os métodos de Weight Moving Average e Distribuição de Poisson são os mais adequados para avaliar a demanda intermitente para o caso da VRG Airline Company S/A.

Abstract:

The stage of design and technological preparation of production is the longest in the process of creating new types of aircraft. To improve the organizational structures of enterprises, consideration of their activities is required not from the point of view of the functioning of structural units, but from the point of view of the organization and course of business processes. The new organizational structure of the company is based on the management of business processes and production resources. In recent years, a tendency has arisen when certain parts of the aircraft are made in different cities, but in the case of IL-276, the most suitable for the production of the entire machine is Aviastar - SP JSC. This is due to the fact that this product will be manufactured on the basis of the existing IL-476 aircraft assembled at this enterprise. In fact, the IL-276 is simply a ―circumcised‖ IL-476. The car has a shortened fuselage in order to facilitate, and only two of the four (closest to the fuselage) engines are left, and the fuel supply is also reduced, which leads to a decrease in weight. The Ulyanovsk plant has large areas already equipped for aircraft of this type, a paint shop and platforms for flight tests, therefore, this company can produce a full production cycle of aircraft, which is economically viable. In addition, at this time, the company has a small workload, and the production of a new product will allow the use of free equipment and specialists.

Abstract:

The aim of the study is to analyse the process of historical growth, transformation and global expansion of the largest Brazilian aircraft industry enterprise – Embraer (Empresa Brasileira de Aeronautica). The company history can be divided into three main stages. The first one lasted from 1969 until the second half of the 1980s. In that stage, the company developed production supported mainly by the government or on license technology. The second stage lasted from the end of the 1980s to the mid-1990s. This was the stage of the crisis and transformation of the company, which ended up with its privatization and recovery. The last stage, lasting from 1996 to 2009, was characterized by dynamic growth of production and sales. The new family of regional jets (ERJ-145 and Embraer 170/190) turned out to be a great selling success which has enabled the company to maintain its position as a global leader in regional jets, which vies with the Canadian Bombardier for the third place in the world ranking of aircraft manufacturers.

Abstract:

The integration of the aircraft design process requires careful management of the computer information system to avoid the use of different standards yet to allow changes to be incorporated as the design develops. The aircraft project manager has to control the total system design. This requires different knowledge and skills to that of the traditional chief designer. Several different software suites have been developed to meet the requirements of 'computer-aided design'. Each of the major manufacturing companies has incorporated a specific CAD system which it standardizes for use in all the sections of the company; and they require subcontractors to be able to use a similar system.

Abstract:

The development of the Ultra High Bypass (UHB) engine for transport aircraft introduces sonic fatigue as a major structural design challenge. UHB engines generate high intensity acoustic tones associated with the harmonics of the propeller blades. Current analysis methods and structural design approaches to prevent sonic fatigue cracks are based on techniques developed in the 1960s for broadband random jet-noise excitation. The high intensity noise testing and analysis completed to develop a sonic fatigue treatment design for the UHB Demonstrator aircraft are discussed. The evaluation included progressive wave tube (PWT) and shaker table testing conducted on representative aircraft components in the laboratory. Also discussed are the sonic fatigue treatment designs developed and flight tested on the UHB Demonstrator aircraft by Douglas Aircraft Company. The tests proved that lightweight and inexpensive treatments can be developed that will provide protection against sonic fatigue.

Abstract:

The purpose of this study is to develop a value stream mapping for a production in an aircraft manufacturing company. The process begins with creating a current state map and understands the production flow and the current cycle times. This provides the information needed to produce a future state map. The goal is to identify and eliminate the waste, which is any activity that does not add value to the final product, in the production process. In order to collect the information needed, the study was conducted within the production facility to enable the researcher gained knowledge and familiarized with the production flow and the activities being performed at the shop floor. Parameters such as cycle times, down times, work in process (WIP) for inventory and material, and information flow paths were recorded. This information will enable the researcher to visualize the current state of the process activities by mapping the material and information flow and looking for opportunities to eliminate wastes. ARENA simulation software package was used to simulate and analyze the process flow and times. Result from the analysis shows that there are areas where the company can further improve their production system. The results show the improvement of the cycle time up to 22% based on the new proposed arrangement of the layout. Therefore the propose layout will be guided to the company in order to improve their production.

Abstract:

V-ROL N is an aircraft steel produced in Czech Republic at Poldi Kladno, used for many years for a manufacture of aircraft landing gears, particularly for a small passenger aircraft L 410. The V-ROL N steel, known by its very good or even excellent fatigue and fracture properties, has not been more available due to recent privatization of the company. Therefore, a substitution of materials previously used became an issue. The paper contains results of a comprehensive experimental programme aimed at comparison of the V-ROL N steel used in the past, still available for research purposes, with another steel of a similar type, VIP P-ROL N steel, manufactured in Czech Republic by another company. Fatigue resistance of both versions can be considered as good. Slightly higher scatter of fatigue results of VIP P-ROL N version can be attributed to an occurrence of impurities, although quite rare, responsible for fatigue crack initiation.

Abstract:

A structural-parametric analysis of the development of the global aviation market has been done and by the example of the development of the domestic helicopter industry, it was shown that the main revenue in the life cycle of aviation technology lies in the area of aviation service. The graphical model of the business objective in the development and operation of helicopters shows the need to maximize the service life of aircraft and reduce downtime. One of the forms that show these features was leasing with the inclusion of services in affiliated centers. At the request of the lessee, the leasing company may also provide additional services for advertising, recruitment, etc. Wet lease is mainly used by companies that manufacture special equipment or are engaged in wholesale activities in the field of aviation, i.e. in fact, they are monopolists. One of the ways to diversify sources of income is the sale of licenses for the production and maintenance of helicopters in the framework of the product lifecycle. Lost sales of helicopters for a holding company must be replenished through monopolization of the service and regulation of prices in this market. In general, the provision of service is a high-tech and profitable business. It requires constant monitoring and quality control of services at all stages of the life cycle of a helicopter. Income growth will be associated with an increase in the term and area of the business goal.

Abstract:

An aircraft company needs to "secure" their aircraft engine for a good maintenance system to keep the optimum engine's performance during the flight. This paper proposed maintenance analysis and scenario for the CT7, the main engine for aircraft at NTP company. A failure data record from four critical components of the CT7 engine is analyzed using Reliability Centered Maintenance (RCM) and Risk Based Maintenance (RBM) methods to obtain the optimum maintenance interval task for the critical subsystem of the CT7 engine and also seeing the risk of maintenance cost of the engine's failure effect. The RCM analysis result obtained seven scheduled on condition task, six scheduled discard task, and three scheduled restoration task. The interval of the maintenance schedule of each critical component varies according to the function obtained. And based RBM analysis, the risk from system performance loss is got $ 7.014.841, 90. Meanwhile, the total cost of maintenance interval based on a calculation of optimal time interval got $1.885.612, 82. Keywords— preventive maintenance, reliability-centered maintenance, risk-based maintenance, risk priority number.

Abstract:

PurposeThe objective of this work is to provide a novel aircraft allocation model for fractional business aviation. This model may provide decision-makers with alternative routing solutions that take into consideration preventive maintenance and failure prognostics information. The expected results are more efficient routing solutions when compared to conventional planning models, to help decision-makers improve operations and maintenance planning.Design/methodology/approachThe model is a mixed integer linear problem formulation addressing and considering preventive maintenance and failure prognostics for optimal operations. Numerical experiments were performed using both field and synthetic data to validate the proposed method. All instances are solved using branch, price and cut algorithms from open-source software.FindingsThe results obtained in this study show that the use of failure prognostics information in aircraft routing can provide improvements in overall planning. By choosing slightly longer flight legs, the flight cost will increase, but putting an aircraft with a higher risk of failure on a leg inbound to a maintenance base can reduce maintenance and overall operating cost.Originality/valueThe model and method provide decision-makers with routing solutions that consider new aspects of planning, not used in previous works, such as failure. Most of the literature focuses on solving routing problems for large commercial airlines. Considering that, few solutions are found in literature for fractional business operators, which have their own operational particularities, such as a company managing a fleet of aircraft belonging to multiple shareowners. In such operation, clients may not always fly in the aircraft that they are shareowners, but an aircraft from the fractional fleet of the same category. Here, the company managing the aircraft guarantees that an aircraft will be ready to attend client demands in minimum time. One of the major differences from other models of operation is the dynamic nature of its flight demands, thus requiring flexible and agile planning limiting the available time to find a routing solution.

Abstract:

This paper focus on a development and implementation of a systematic guided lean and six-sigma approach to solve high rejection rate on part disposal at composite manufacturing for aircraft component industry. The approach is called PaDLeSS which is stand for Part Disposal reduction through Lean and Six Sigma. PaDLeSS is developed from the integration between lean and six sigma tools with a guided by R-DMAIC-S approach and it is focused on the reduction of parts disposal mainly at a composite manufacturing panel for aircraft components. Since a unit price for one composite panel of aircraftcomponent is very high, a systematic approach to improve, control and sustain the process is necessary in order to reduce parts rejection rate in the process, outgoing process and at the customer process. PaDLeSS is devided into two main phases ; development phase and implementation phase. In a development phase, a thorough study was carried out from previous works and match with a requirement needed in part disposal reduction at composite manufacturing for an aircraft panel. The related data related to the parts disposal at the manufacturing line was also analyzed to get actual situation for improvement monitoring. Then, in the implementation phase, a few case studies selected at company A (composite panel for aircraft manufacturing company in Malaysia) for verification and validation purposes. In this paper, the development of PaDLeSS will be presented.

Abstract:

Evolving aircraft and engine technologies, as well as advancements in avionics, have resulted in a new generation of fighter aircraft. In order for an air force to remain survivable in such an environment it must face the necessity of either acquiring new aircraft or upgrading its fleet. Today, acquisition of new aircraft may not be an economically or politically viable solution. The newest aircraft, those with a thrust-to-weight ratio exceeding 1 to 1, generally exceed $20 million, exclusive of support costs. Politically, sale of such state-of-the-art aircraft to friendly countries may not be possible given the current FX aircraft export policy, and the fiscal posture of the country. However, there is an alternative to new aircraft acquisition, and that is functional modernization: the modernization of potentially viable systems through the implementation of new and available technologies. The Boeing Military Airplane Company and Pratt & Whitney have teamed in the newest aircraft functional modernization proposal, the F-4 Super Phantom. The full modernization package includes a new centerline conformal fuel tank, new digital avionics, and re-engining with new PW1120 engines. This paper examines the initial feasibility study conducted by Pratt & Whitney and Boeing to determine the feasibility of a functionally modernized F-4.

Abstract:

Business growth and ease of mobility have played a significant role in the increasing use of corporate aircraft through the 21st century. Along with the increased use of corporate aircraft, personal use of corporate aircraft has also been on the rise. With this increased use, the tax treatment of the personal use of corporate aircraft has become much more visible and controversial. This paper tracks the changes in the law and focuses on the tax policy issues related to the equity in the reporting of income by the employee and the deduction claimed by the corporation. Specifically, this paper addresses the three-fold problem related to the current inequities of the current and proposed laws: What amount should be included as compensation by the employee as a fringe benefit for the personal use of company-owned aircraft? How much should the employer deduct for the operating cost of the aircraft for personal use? Should these amounts, compensation and deduction, be equal? The paper also addresses the horizontal inequities imposed by the current laws upon shareholders, different types of employees, corporations, and private citizens.

Abstract:

Shiftwork disrupts the sleep-wake cycle, leading to sleepiness, fatigue, and performance impairment, with implications for occupational health and safety. Aircraft maintenance crews work a 24-hour shift rotation and sustain flight punctuality rate of job stress.If an error occurs during the aircraft maintenance process, this error may become a potential risk factor for flight safety.This paper focuses on optimal work shift scheduling to reduce the fatigue of aircraft maintenance crews. We model fatigue as a dynamic system, and the objective is to find the optimal shift schedules that minimize the maximum fatigue values. Various constraints such as holidays, company and government regulations are included in our model. This optimization problem is formulated as a mixed-integer program, in which the shift assignments are described by 0-1 variables. We take a sample aircraft maintenance crews schedule to demonstrate the proposed methods.

Abstract:

Computational fluid dynamics is employed to predict the aerodynamic properties of the prototypical trailing-edge control surfaces for a small, regional transport, commercial aircraft. The virtual experiments are performed at operational flight conditions, by resolving the mean turbulent flow field around a realistic model of the whole aircraft. The Reynolds-averaged Navier–Stokes approach is used, where the governing equations are solved with a finite volume-based numerical method. The effectiveness of the flight control system, during a hypothetical conceptual pre-design phase, is studied by conducting simulations at different angles of deflection, and examining the variation of the aerodynamic loading coefficients. The proposed computational modeling approach is verified to have good practical potential, also compared with reference industrial data provided by the Leonardo Aircraft Company.

Abstract:

Today airlines are challenging two opposite goals: minimization of flight fuel consumption and minimization of elapsed flight time. A well‐known cost structure and cost generators represent significant pre‐conditions for defining cost optimization strategy in an airline company. Airline company management has a limited set of tools for cost managing, which include the following documents: Performance Engineers’ Manual and Aircraft Flight Manual. In this particular paper review we discuss the problem of vertical flight path of turbo‐fan aircraft, where we point out the impact of the choice of climb technique on the overall en route flight profile costs. In temporary aircraft flight preparation process, there is no stressing out the significance of the climb phase in minimizing costs of this particular flight phase. In the paper we show the procedure of defining optimal climbing resulting minimum costs, but also optimal function operational adjustment to the climb schedule. This way of the approximation of optimal function and its adjustment to the operational use enables the application of minimal cost climbing technique in operational use of transportation aircraft. On short‐haul flights, climb phase can reduce cruise flight length up to 60% of total range. In the paper, we show the impact of climb regime on flight profile of turbo‐fan aircraft considering the usage of time, fuel and costs. The impact is shown according to the data taken from the Performance Engineers Manual. The impact stresses the importance of minimum costs climbing regime to cutting down total flight costs. It also shows the conditions which need to be fulfilled in order to apply minimum costs climbing technique. We identify the scope of CAS speed during climb and TOC for flights minimum total expenses by using minimum costs climbing technique. Conditions for achieving minimum costs climbing technique are the results of the logarithmic differential. In order to achieve optimal numerical results we used Newton‐Raphson formula. Santrauka Šiandien oro transporte svarbūs du tikslai: skrydžio metu sunaudojamo kuro mažinimas ir skrydžio laiko trumpinimas. Žinoma kainos struktūra ir kainos komponentės yra reikšmingos išankstinės sąlygos, padedančios sudaryti kainos optimizavimo strategiją oro transporto bendrovėje. Oro transporto bendrovės valdytojai turi ribotą sąnaudų valdymo priemonių komplektą – tai „Priežiūros inžinieriaus vadovas“ ir „Orlaivio skrydžio vadovas“. Straipsnyje aptariama turbosraigtinio lėktuvo vertikalios skrydžio krypties problema, parodomas pasirinktos kilimo technikos poveikis bendrai skrydžio kainai.

Straipsnyje pateikiama procedūra, kaip nustatyti optimalų orlaivio kilimą mažiausiomis sąnaudomis, taip pat optimalumo funkcijos korekciją kilimo plane. Optimalumo funkcijos aproksimavimas ir jos naudojimas leidžia taikyti mažiausių sąnaudų kilimo techniką lėktuve. Trumpalaikiuose skrydžiuose kilimo fazė gali sumažinti kruizinio skrydžio trukmę iki 60 proc.

Abstract:

On March 13, 1998, Dr. Hans Joachim Pabst von Ohain, co-inventor of the turbojet, passed away at the age of 86. As a young doctoral student, von Ohain conceived of and built a demonstrator turbojet engine. He was hired by the Heinkel Aircraft Company in 1936 and under intense time pressure imposed by Ernst Heinkel, designed the world’s first flight turbojet engine. This paper traces the technical antecedents leading to historic jet-powered flight made on August 27, 1939 by a Heinkel He 178 aircraft powered by von Ohain’s HeS 3B turbojet. During his tenure at Heinkel and thereafter at the Heinkel-Hirth Company, he was responsible for a series of turbojet engines culminating in the advanced second generation HeS 011 with a thrust of 2860 lbs. This paper is a tribute to an outstanding scientist who made possible the turbojet revolution and who will forever be remembered as the inventor of the world’s first flight turbojet.
