Abstract:
Self-organising radio systems have been proposed for aeronautical and maritime communication, navigation and surveillance applications. In aviation, the introduction of the VHF Data Link (VDL) Mode 4 is currently being discussed, while the implementation of Automatic Identification Systems (AIS) is planned in the maritime domain. Operating in an autonomous mode, a self-organising radio system employing Time Division Multiple Access (TDMA) does not require a terrestrial infrastructure, such as base stations. The concept of self-organisation is based on the cooperative behaviour of a large number of users sharing a common VHF radio channel. Analyses have shown that uncoordinated stations, so-called hidden users, can cause interference in self-organising radio systems. This paper presents two different approaches to autonomous self-organisation together with the results of investigations of intra-system interference. Such analyses may help to introduce potential improvements to the system performance, which reduce the effect of hidden users in this very promising GNSS-based technology.

Abstract:
The goal of this symposium is to present the status and future directions of programs aimed at consideration of human factors early in military system design. Military initiatives of this nature are not new, but in the past they have not become integral parts of the military system acquisition process. Recent programs in each service, however, reflect more serious and in-depth attempts to use human factors data to influence and evaluate system design than has been the case in the past. The Army now requires MANPRINT analyses, Navy HARDMAN analyses are mandated, and the Air Force is now pilot testing its own program called MPTIS. This symposium consists of introductory remarks by Dr. Joseph Peters of Science Applications International Corporation, and papers from LTC William 0. Blackwood, HQ Department of the Army, CDR George S. Council, Jr., Office of the Chief of Naval Operations, and COL AI Grieshaber, HQ, U. S. Air Force. Dr. Peters' paper, “Human Factors Issues in Military System Design,” defines “human factors” as a combination of human factors engineering, biomedical engineering, manpower/personnel, and training elements. The paper presents three measures of success of human factors programs early in system acquisition: long-lasting policy, committed management, and availability of scientific technology for program Implementation and evaluation. LTC Blackwood's paper discusses the importance the Army places on its MANPRINT program. MANPRINT program history, status, and possible program evolution are addressed. CDR Council's paper addresses the potential for the addition of human factors to the Navy HARDMAN program which addresses manpower, personnel, and training. CDR Council suggests that human factors advocates present a human factors program which is clearly defined and limited in scope to render it easily appreciated by Navy management, and that advocates can benefit from lessons learned during the institutionalization of HARDMAN. COL Grieshaber's paper “MPT in the Air Force” describes a pilot MPT (manpower, personnel, training) program at Aeronautical Systems Division, Wright Patterson AFB. This program will analyze aircraft system designs for their MPT requirements, suggest design changes where requirements exceed Air Force availabilities, and assess design changes for their MPT impact.

Abstract:
This article highlights that for centuries although space was the realm of wonder and fascination, of fiction and children’s bedtime stories, of shooting balls of fire and faraway heavenly bodies; still it was less than 50 years ago that things began to change in earnest. Enormous engineering resources were invested in the US space program during the 1960s. By the end of the decade, engineers had gained a sufficient level of knowledge about chemical rockets and storable propellants and turned their attention to other technologies, such as noise control and advanced computer systems. In its tradition of recognizing technological achievement, ASME has bestowed honors and awards on numerous engineers and scientists associated with the nation's space program. ASME’s publications and conferences have been important vehicles for disseminating technical information on aerospace and aeronautics technology. The Society’s Aerospace Division, which predates the lunar program, has been one of the most active sectors of ASME's technical divisions.

Abstract:
Armstrong Laboratory, Logistics Research Division performed an evaluation to determine whether flightline maintenance was improved by using a computerized, integrated maintenance information system (IMIS) for different types of users. The laboratory's evaluation overcame several logistical problems common to conducting research outside a laboratory setting. Such problems include obtaining representative subjects, controlling for extraneous variables, and gathering adequate sample data. The present study includes 24 maintenance technicians (12 avionics specialists and 12 crew chief non-specialists). Each subject performed 12 maintenance tasks (6 using electronic and 6 using paper presentation). Subjective workload ratings and objective performance times were measured. Subjective workload (using National Aeronautics and Space Administration-Task Load Index (NASA-TLX)) and objective performance results revealed similar interactions. Using paper-based presentations, crew chiefs gave significantly higher subjective workload ratings than avionics specialists and significantly longer total performance time (e.g., time-to-complete). However, there were no significant differences between the two groups when using electronic-based presentations.

Abstract:
This is an updated and revised version of a paper originally presented to a CNS/ATM Forum of representatives from the States, airlines and air traffic service provider organisations of the Pacific region meeting in Sydney, Australia on 16 April 1998. The Forum was organised under the auspices of the Australian and New Zealand Divisions of the Royal Aeronautical Society.There are many legal issues involved in the provision and use of new technology based on satellite navigation and communications in Air Traffic Management Systems. These include aspects of international space law, international air law and domestic state law. Spanning these aspects are regional provisions and the role of ICAO. This paper considers these issues with particular reference to the Pacific region, which is in the lead in adopting the new technology, and concludes that much of the existing law applies, but that new law is also required if the legal framework is to keep pace with introduction of the new technology.

Abstract:
In July 2005, the National Aeronautics and Space Administration investigated tropical cyclogenesis, hurricane structure, and intensity change in the eastern North Pacific and western Atlantic using its ER-2 high-altitude research aircraft. The campaign, called the Tropical Cloud Systems and Processes (TCSP) experiment, was conducted in conjunction with the National Oceanic and Atmospheric Administration/Hurricane Research Division's Intensity Forecasting Experiment. A number of in situ and remote sensor datasets were collected inside and above four tropical cyclones representing a broad spectrum of tropical cyclone intensity and development in diverse environments. While the TCSP datasets directly address several key hypotheses governing tropical cyclone formation, including the role of vertical wind shear, dynamics of convective bursts, and upscale growth of the initial vortex, two of the storms sampled were also unusually strong, early season storms. Highlights from the genesis missions are described in this article, along with some of the unexpected results from the campaign. Interesting observations include an extremely intense, highly electrified convective tower in the eyewall of Hurricane Emily and a broad region of mesoscale subsidence detected in the lower stratosphere over landfalling Tropical Storm Gert.

Abstract:
Purpose – This paper, a “Q & A interview” conducted by Joanne Pransky of Industrial Robot Journal, aims to impart the combined technological, business and personal experience of a prominent, robotic industry engineer-turned entrepreneur regarding the evolution, commercialization and challenges of bringing a technological invention to market. Design/methodology/approach – The interviewee is Dr Robert Ambrose, Chief, Software, Robotics and Simulation Division at National Aeronautics and Space Administration (NASA)’s Johnson Space Center in Houston, Texas. As a young child, even before he started school, Dr Ambrose knew, after seeing the Apollo 11 moonshot, that he wanted to work for NASA. Dr Ambrose describes his career journey into space robotics and shares his teams’ experiences and the importance of the development of Robonaut, a humanoid robotic project designed to work with humans both on Earth and in space. Findings – Dr Ambrose received his MS and BS degrees in mechanical engineering from Washington University in St. Louis, and his PhD in mechanical engineering from the University of Texas at Austin. Dr Ambrose heads the flight spacecraft software, space robotics and system simulations for human spaceflight missions. He oversees on-orbit robotic systems for the International Space Station (ISS), the development of software for the Multi-Purpose Crew Vehicle and future human spaceflight systems, simulations for engineering development and training, hardware in the loop facilities for anomaly resolution and crew training and the technology branch for development of new robotic systems. Dr Ambrose also serves as a Principal Investigator for NASA’s Space Technologies Mission Directorate, overseeing research and formulating new starts in the domains of robotics and autonomous systems. He co-chairs the Office of the Chief Technologist (OCT) Robotics, Tele-Robotics and Autonomous Systems roadmap team for the agency’s technology program, and is the robotics lead for the agency’s human spaceflight architecture study teams. Working with the Office of Science and Technology Policy (OSTP), Dr Ambrose is the Technical Point of Contact for NASA’s collaboration in the National Robotics Initiative (NRI). Originality/value – Dr Ambrose not only realized his own childhood dream by pursuing a career at NASA, but he also fulfilled a 15-year national dream by putting the first humanoid robot into space. After seeking a graduate university that would allow him to do research at NASA, it didn’t take long for Dr Ambrose to foresee that the importance of NASA’s future would be in robots and humans working side-by-side. Through the leadership of Dr Ambrose, NASA formed a strategic partnership with General Motors (GM) and together they built Robonaut, a highly dexterous, anthropomorphic robot. The latest Robonaut version, R2, has nearly 50 patents available for licensing. One of the many technology spinoffs from R2 is the innovative Human Grasp Assist device, or Robo-Glove, designed to increase the strength of a human’s grasp.

Product development is a major source of competitive advantage in the commercial aircraft business. Judiciously implementing commonality across a range of products yields important benefits in this area. Thus, measuring the quality of commonality implementation is extremely beneficial for aircraft manufacturers. This thesis analyses the concept of commonality and divides it into three constructs that can help understand all of its aspects: standardization, reusability and modularity. This work then presents a set of metrics measuring each of these aspects, from the point of view of the manufacturer and of the customer. The appropriateness of this set of metrics is then tested in a case study analyzing the efficiency of commonality implementation in the cockpit of two well-known commercial aircraft families: the Airbus A320 family and the Boeing 737 family. This thesis further describes what additional analysis should be performed to validate the set of metrics for broader applications. After documenting the efficiency of the set of metrics, this thesis analyses the current practices of commonality management in commercial aviation. It finally explores some of the limitations of the concept of commonality and sketches solutions to overcome them.

This thesis is concerned with the design of complex artificial systems. For such systems, there is a growing need to deliver value to stakeholders beyond the initial functional requirements and to cope with rapidly changing outer environments. This thesis presents a conceptual framework and a structured approach for thinking about and designing systems that can exhibit the emergence of desirable lifecycle properties (i.e., ilities). To set the ground for the research contributions, a literature overview on (1) complex sociotechnical systems, (2) uncertainty in such systems, and (3) ways to cope with such uncertainty is given. Furthermore, the larger research effort concerning a method for architecting Systems of Systems with ilities is discussed to frame the remainder of the thesis. The dynamic system perspective for design is discussed, as well as a formal way of modeling the space of possibilities for designers of complex systems (i.e., what the system can be, as well as what its outer environment and expectations can be). In this perspective, uncertainty is modeled as perturbations, which are operators on these spaces of possibilities. Similarly, ility-driving elements (IDEs) are introduced and modeled as operators on such spaces as well. Two main types of ility-driving elements are discussed and formally defined: change options and resistance properties. The former, akin to real options in business, enable the system to change over time so as to cope with perturbations and sustain (or enhance) value delivery. The latter, on the other hand, impede undesired changes in system value delivery. Lastly, IDE Analysis - a structured approach for generating, evaluating and selecting ility-driving elements - is introduced, and demonstrated on a running case application to a Maritime Security System of Systems. This approach requires an initial baseline design concept, and considers a set of relevant perturbations as a starting point. The thesis ends with general discussions around applicability of research and possible areas for future research, as well as conclusions regarding key contributions.

The evolutionary nature of Unmanned and Autonomous Systems of Systems (UASoS) acquisition needs to be matched by equally evolutionary test capabilities in the future. There is currently no standard method to determine what is required to make programs safe for deployment, nor is there the ability to make effective contingency plans should testing requirements change. Spending too much effort designing goals when causal understandings are still in flux is inefficient. As such, policy making and enforcing policies on the deployment of UASoS becomes very problematic. Testing is required especially for UASoS to identify risk, improve capabilities and minimize unpleasant surprises. It needs to be effective and focused, determining the issues and working towards ensuring the risks of the UASoS are known. It is important to have adequate feedback loops, a culture of information sharing and learning from best practices, as well as the development of metrics and/or performance indicators that adequately reflect the effectiveness of the test process. This thesis describes a model that is part of a larger Prescriptive and Adaptive Testing Framework (PATFrame), which uses knowledge acquisition to minimize risk through a decision support system. This work presents the cost and risk considerations for UASoS T&E and provides the preliminary parameters to conduct trade-off analyses for T&E. It also provides guidance on how the DoD can adopt such tools to transform the DoD T&E enterprise. The model is a combination of information collected from various normative and descriptive views of testing based on literature review, surveys, and interviews with members of the Department of Defense (DoD) T&E community A cost estimation model can have significant impacts on how the DoD currently does testing and would help maximize the use of the resources available. It is a model based method for calculating effort for test and evaluation and forms a baseline for strategic decision making in DoD acquisition programs. The intent is to predict within a certain probability that a test program can be completed within a certain budget given the assumptions used in characterizing the UASoS and the T&E process.

Systems engineering exists as a discipline to enable organizations to control and manage the development of complex hardware and software. These methods are particularly essential in the development of space systems, which feature extremely challenging demands for engineering performance, coupled with extremely limited resources for accomplishing them. Success requires careful attention to the relationships between various components as well as the organizations constructing them. Unfortunately, aerospace organizations routinely struggle with the traditional systems engineering process, and as a result, program managers experience pressure to conclude, curtail or ignore critical elements. The consequence is that cost overruns, slipped schedules and outright failures are a regular feature of the industry. Recent advances in Model-Based Systems Engineering (MBSE) tools and methods provide an opportunity to rectify these issues by better integrating systems engineering capabilities into the engineering development process. By directly networking the engineering models used in the development process to each other and the systems diagrams which describe them, MBSE has the potential to make the development process more responsive to design evolutions and account for changes across the entire space system. In this way, systems engineering could become a more integrated part of the development process and better contribute to successful space systems. Unfortunately, current-generation MBSE tools and methods have yet to fully realize this potential. Critical capability gaps have deterred adoption and relegated their use to academic endeavors. This thesis argues that many of the difficulties encountered in current systems engineering practice - as well as attempts to reform that practice - can be explained with reference to distributed cognition, control theory and the wider field of cognitive systems engineering. Existing tools and techniques, while nominally fulfilling the purposes assigned to them, generally fail to adequately support systems engineers in the cognitive tasks associated with the control and management of development processes. As a result, systems engineers are frequently overburdened in their roles and are unable to fully address the myriad of concerns relevant to the design of good system solutions. A cognitive analysis of the software and hardware devices situated in practical instantiations of development activities can reveal opportunities to improve performance and enhance effectiveness. Such changes would make systems engineering tools easier to use and better tailored to the needs of the system engineering task, encouraging adoption and accomplishing the goals of the MBSE community. A cognitively-informed MBSE approach, in addition to better linking the elements of the engineering effort, can also be used to link the engineering effort to the higher-level needs which drive the engineering process in the first place. One of the biggest challenges any engineering organization faces is managing the "how," "why," and "what" of system development, that is, the engineering logic which determines "how" a given program or system will be built and the business, political or policy logic which determines "why" and "what" system will come into being. Often, these latter concerns are poorly addressed by the space system development process, which can lead to sub-optimal outcomes for the wider organizations involved in the engineering project. Methods which better systematize, quantify and direct the process of stakeholder analysis, concept generation and architecture exploration can aid in the selection of system architectures that better meet the strategic objectives of the organizations which develop and operate space systems. Such methods are demonstrated with respect to an evaluation of possible architectures for a notional large, ultraviolet-visible-near-infrared (UV-VIS-NIR) optical space telescope to succeed Hubble in the late 2020s to early 2030s timeframe. This research draws on MBSE concepts and the legacy of tradespace modeling for system design to extend tradespace modeling to the realm of architectural exploration. Its particular interest is the quantitative treatment of "programmatic factors": the business, policy and political considerations which govern high-level decision-making. Through modeling, these considerations can be directly associated with engineering performance factors, enabling better selection decisions and reinforcing linkages and understanding between the engineering and management levels within an organization. It is intended to leverage existing work in stakeholder modeling, real options, strategic evolution and tradespace exploration to bridge existing divisions between systems engineering and programmatic decision-making processes which can lead to poorly optimized architectures. It is geared towards systems engineers and program managers seeking to account for organizational and higher-level stakeholder needs during the tradespace exploration process and more efficiently and practically integrate these decision frameworks in real-world engineering environments.

Program failures have plagued the defense and aerospace industry for decades, as unanticipated cost and schedule overruns have rendered the development of systems ineffective in terms of time and cost considerations. This raises the need to holistically include performance, cost and schedule considerations during the early-phase design of systems to perform valuable tradeoffs that derive more feasible and affordable solutions. This paradigm is the design for affordability. This design for affordability conundrum is targeted at defense and aerospace systems, which have complex mission requirements and stakeholder involvement that are susceptible to changes and perturbations over time. Without a systematic framework, the design for affordability process can potentially become cognitively challenging to system architects and lead to unsatisfactory results. To resolve affordability, it can first be defined as the property of becoming or remaining feasible relative to resource needs and resource constraints over time. Affordability can then be treated as an ility that drives the design of more affordable yet technically sound architectures. Tradespace-based methods are introduced to drive affordability and incorporate these holistic considerations into the design process. They facilitate the systematic and disciplined search for affordable solutions to the system, program and portfolio of interest. Multi-Attribute Tradespace Exploration (MATE), Epoch-Era Analysis (EEA) and the Multi-Attribute Expense (MAE) function were modified for affordability analysis. Their feasibility was demonstrated through application to two design case studies. Results from both case studies demonstrated the dynamic tradeoffs among performance, cost and schedule parameters. Tradespace-based methods can thus be applied to the progressive design of systems, programs and portfolios using either a bottom-up or top-down approach to deliver affordable solutions in these cases. Affordability is not only an engineering problem; it is also a policy and management problem. Therefore, affordability can be approached through perspectives beyond engineering design. New policies and refined management practices can be used alongside tradespace-based methods for affordability analysis to ensure the continued delivery of affordable systems for the future.

The continued growth of the aviation industry poses a challenge to policy-makers and industry stakeholders as each decision represents a trade-off on efficiency, equity, and environmental impact. The Aviation environmental Portfolio Management Tool - Impacts (APMT-Impacts) module has been developed to calculate physical damages from aviation's impact on ambient noise, local air quality, and climate change. The main objective of this thesis is the continued development of a framework for examining aviation environmental policy by expanding the current modeling capability and addressing key shortcomings in decision-making practices. First, climate modeling assumptions, particularly those related to background emissions scenarios and short-lived radiative forcing agents, are examined, and a temperature-response model based on a two-box ocean model with advective flux and diffusion is developed. Second, a cost-benefit analysis of a proposed NOx Stringency policy is performed. The analysis shows that increased engine stringency is not cost-beneficial under several traditional lenses and discount rates. However, lenses accounting for conservative assumptions in air quality and uncertainty in technology cost estimates show benefits for a range of stringency increases highlighting the need for flexibility in the analysis approach, the use of engineering judgment, and open communication between decision-makers and analysts. This cost-benefit analysis is compared to a traditional cost-effectiveness approach. Finally, this thesis lays out the need for supplemental analyses on a regional scale to address who bears the cost and gains the benefits of a given policy.

To this end, three propositions are explored: (i) metrics and measurement systems drive transformation, (ii) employee engagement is a proxy to gauge transformation progress; and (iii) metric considerations enable enterprise transformation when systematically executed as part of a transformation roadmap. To explore this problem, the aerospace measurement community was consulted to help grasp a better understanding of the context in which transformation is currently defined and measured. Once the problem space was defined, the environment of doing research with the enterprise as the unit of analysis was described with the intent of exploring the role of metrics and transformation. In particular, the performance measurement literature helped identify tools and methods used to select metrics to enable decision making at the enterprise level. After this review, two case studies were performed, considering: (1) the implementation of a bottom-up measurement system to drive transformation and (2) the effect of a top-down corporate measurement system on the enterprise. The first case study revealed insights regarding the benefits and challenges of implementing measurement systems and highlighted the use of employee engagement as a proxy to measure enterprise transformation. In the second case study, contemporary measurement issues were discussed and mapped to an Eight Views of the Enterprise analysis to identify critical enterprise interactions.
(cont.) Ultimately, the Lean Advancement Initiative's Enterprise Transformation Roadmap was used as a method for depicting how performance measurement can help enable enterprise transformation. The implications of research in metrics for enterprise transformation span across thee areas: (1) the extensive literature reviews provide an academic contribution for performing enterprise and measurement research; (2) a common language and framework for exploring measurement problems is depicted for practitioners through the case study analysis; and (3) a connection between enterprise measurement and enterprise transformation is established to drive future transformation success.

Engineering change management is a critical and challenging process within product development. One pervasive source of difficulty for this process is the phenomenon of change propagation, by which a change to one part or element of a design requires additional changes throughout the product. Research efforts to understand and manage change propagation have largely drawn on network analysis. This thesis builds upon past research by introducing a multilayer network model that incorporates three proposed layers, or domains, that contribute to change propagation: namely, the product layer, change layer, and social layer. Each layer contains a distinct network of nodes and intralayer edges, but also connects to the other two layers through inter-layer dependencies. The model facilitates extensive quantitative analysis of change propagation using a repository of single-layer, double-layer, and triple-layer tools and metrics. A case study of a large technical program, which managed over 41,000 change requests in eight years, is employed to demonstrate the practical utility of the model. Most significantly, the case study explores the program's social layer and discovers a real-world correspondence between an engineer's organizational role and the propagation effects of his or her work, as measured by the newly proposed Engineer Change Propagation Index (Engineer-CPI). The case study also reveals that parent-child propagation often spanned more than one, but never more than three, system interfaces, thus confirming the possibility of indirect propagation. Finally, the study finds that propagation always stopped after five, and rarely more than four, generations of descendants. In all, the multilayer network model's holistic approach has significant policy implications for engineering change management in industry.

Title as it appears in MIT Commencement Exercises program, June 2013: Analysis of short Innovation contests as a strategy for technology procurement in government. Cataloged from PDF version of thesis
Includes bibliographical references (p. 83-88).
Technologies over the past three decades have democratized the tools of knowledge creation, thus creating increasing communities of innovators outside traditional organizations' boundaries. Cost effective ways of leveraging these innovative crowds can be imperative to creating and maintaining value. One specific way for organizations to tap into this diverse audience is through the use of short innovation contests. The purpose of this thesis is to better understand the application of this strategy as a tool for technology procurement in the context of government. Through a contest, participants approach a well-defined challenge independently, conducting different experiments to find a solution. The combination of these various "trials" leads to an increased probability for a government agency to find one particularly good, extreme-value solution. Contests can also allow government agencies to engage individuals who are normally unable or unwilling to compete in traditional government contracts, thus alleviating certain imperfections in the competitive market of government contracting. This open design strategy for procurement is fundamentally different than traditional procurement methods. For this reason, there is inherent uncertainty in the organizational implications contest implementation will have in government agencies which has made program managers hesitant to employ this strategy in their programs. This thesis sheds light on the cost structure, program management implications, and policy considerations for short innovation contests. An empirical analysis is presented for four short innovation contests used for technology procurement in different government agencies. For each case study, the cost of the contest was compared to traditional procurement and key program management considerations were identified. Additionally, recent policy initiatives passed for prize-based contests were analyzed for their applicability to short innovation contests. It was found that three of the four contests procured technology solutions for estimated costs of less than half that of traditional procurement methods. It was also found that recent contest policy initiatives were unsuitable for short innovation contests. This thesis provides recommendations for policies appropriate for short innovation contests and considerations that must be made to expand the use of this strategy as a tool for technology procurement in government agencies.

Engineering, management, and social science methodologies have been employed to analyze a new asset tracking and management system for human spaceflight applications. The Massachusetts Institute of Technology and Aurora Flight Sciences developed Rule-based analytic Asset Management for Space Exploration System (RAMSES) via NASA Small- Business Technology Transfer (STTR) Phase I and Phase II contracts. RAMSES leverages Generation II passive Radio Frequency Identification (RFID) technology to automate the tracking the tens of thousands of small, portable cargo assets that are currently stored onboard the International Space Station (ISS). A Monte Carlo Net Present Value analysis found that RAMSES is likely to have significant positive value for NASA when ISS inventory transactions are concentrated in a subset of the total cargo transfer bag (CTB) population, and/or if ISS Operations are continued into 2018/2020. The volume, mass, and accuracy of the RAMSES system have a significant impact upon the estimated NPV. Testing of the prototype hardware in reduced-gravity conditions reaffirmed the viability of the system. Metals cargo objects were detected with up to 100% accuracy, paper with 96%, and water with roughly 93%. Finally, a comparative analysis of RAMSES and five other NASA Small-Business Innovation Research (SBIR) / Small-Business Technology Transfer (STTR) projects identified three non-technical characteristics and/or informal processes that might be unique to SBIR/STTR technologies that are successfully infused into the mainstream NASA innovation system. These included pre-proposal knowledge exchanges between companies and NASA, strong matching of a project with a relevant NASA COTR, and the availability of an infusion opportunity

Abstract:
The T407/GLC38 turboprop/turboshaft engine is a 6000 shaft horsepower (SHP) class gas turbine engine currently under joint development by Textron Lycoming of Stratford, Connecticut, and GE Aircraft Engines of Lynn, Massachusetts, with Bendix Control of South Bend, Indiana, a division of Allied Signal; Ruston Gas Turbines Limited of Great Britain, part of GEC ALSTHOM; and Steel Products Engineering Company (SPECO) of Springfield, Ohio. The powerplant is derived from the highly successful GE27 Modern Technology Demonstrator Engine (MTDE) program, which was conducted under the auspices of the U.S. Army in the mid-1980s. The T407 turboprop is currently under development for the U.S. Navy’s new P-7A anti-submarine warfare (ASW) aircraft. The P-7A will replace the P-3 and is under contract to Lockheed Aeronautical Systems Company (LASC). A T407 turboshaft model is also in development. The GLC38 commercial turboprop version, planned for both business and commuter aircraft, draws considerably on lessons learned through GE and Textron Lycoming’s extensive commercial experience, thereby ensuring the latest state of the art in maintainability, life, reliability, and ease of operation. The T407/GLC38 engine development program, scheduled for completion in December 1991, is uniquely defined to meet the stringent requirements of both Federal Aviation Administration (FAA) regulations and Military Specification MIL-E-008593E. The engine’s primary identity will be commercial, however, as per agreement with the U.S. Navy. The engine’s gas generator core is also part of a joint venture between the Garrett Engine Division of Allied Signal Corporation and GE. Garrett is responsible for developing the fan and power turbine for a new generation turbofan engine, the CFE738. This paper describes the key features of the T407/GLC38 engine design, performance, and development program.

Abstract:
The National Aeronautics and Space Administration (NASA) has selected a closed Brayton cycle (CBC) solar dynamic (SD) power conversion system to provide electric power for the growth phase of Space Station Freedom. This selection was based in part on the comparitive reduction in solar radiation collection made possible by the high efficiency, closed Brayton cycle system when compared to the efficiency of static conversion systems. The smaller required collector area results in a significant reduction in drag in the low earth orbit which is planned for the Space Station. Under contract to the Rocketdyne Division of Rockwell International, the Allied-Signal Aerospace Company, Garrett Fluid Systems Division is developing the Solar Dynamic Power Generating Subsystem (PGS). This subsystem consists of a solar receiver, which accepts sunlight from the multifaceted collector mirror (the concentrator), and a CBC heat engine that converts the solar heat into electricity. This paper will review the design requirements for the Space Station Solar Dynamic Power Module and present results of the PGS cycle analysis and preliminary design.

Abstract:
Abstract The Capstone design requirements have become an integral part of the most engineering curricula in the United States. They all share the goal of developing multidisciplinary designs for real-world problems/applications, often with industry sponsorship. In this paper, the three-capstone design options required by the aerospace engineering department at the University of Kansas are discussed. The aerospace engineering seniors have three design options based on their career interests. These are aircraft design, propulsion system design, and spacecraft system design options. In the aircraft design, our students may select individual or team design for their competitions. In the latter two, the propulsion and spacecraft system designs, the students are grouped in a number of teams, based on the class and team size requirements. The individuals and teams participate and compete in the respective American Institute of Aeronautics and Astronautics (AIAA) Design Competitions at the end of their senior year. Participation in the AIAA Design Competition is one of the course requirements. Written and oral communication is assessed throughout the semester. In this paper, the methodology used in the aerospace engineering propulsion system capstone design is presented.

Abstract:
Supercritical fluids are widely used in aeronautic, astronautic and nuclear engineering. Active cooling is necessary for scramjet engines to survive the extreme heat generated in hypersonic flight. Regenerative cooling system, where engine fuel works as coolants and travels through the cooling tubes along the chamber wall, carrying away heat from the wall via heat convection and endothermic chemical reactions, is developed as an effective thermal management technique. In this paper, experimental results of convective heat transfer performances of aviation kerosene at supercritical pressures were presented. Stainless steel circular tubes having inner diameters of 1and 1.8 mm were investigated for pressures ranging from 3 to 4 MPa, mass flow rates from 1.87 to 2.41 g/s and heat fluxes from 285 to 365 kW/m2. It was found that the heat transfer coefficient increases with mass flow rate at the former part of the tube. However, as the Reynolds increases significantly at the latter part of the tube at relatively low mass flow rate, the heat transfer coefficient increases dramatically at the latter part of the tube at relatively low mass flow rate. The effect of heat flux on heat transfer is complicated, while the effect of pressure on heat transfer is insignificant. The experimental results also indicated that the heat transfer coefficient decreases with the reduction in tube diameter. The heat transfer behaviors in relation to changes in tube sizes might be caused by the buoyancy effect.
