Extensive numerical methods for computing design sensitivity are included in the text for practical application and software development. The numerical method allows integration of CAD-FEA-DSA software tools, so that design optimization can be carried out using CAD geometric models instead of FEA models. This capability allows integration of CAD-CAE-CAM so that optimized designs can be manufactured effectively.
The authors of this text have written a comprehensive introduction to the modeling and optimization problems encountered when designing new propulsion systems for passenger cars. It is intended for persons interested in the analysis and optimization of vehicle propulsion systems. Its focus is on the control-oriented mathematical description of the physical processes and on the model-based optimization of the system structure and of the supervisory control algorithms.
Boeing's 737 is indisputably the most popular and arguably the safest commercial airliner in the world. But the plane had a lethal flaw, and only after several disastrous crashes and years of painstaking investigation was the mystery of its rudder failure solved. This book tells the story of how engineers and scientists finally uncovered the defect that had been engineered into the plane. One of its novel features is that it portrays the complex interaction of different experts and opposing interests in investigating and solving the mystery of this single crash.
The 24 papers presented at the international concluding colloquium of the German priority programme (DFG-Verbundschwerpunktprogramm) "Transition," held in April 2002 in Stuttgart. The unique and successful programme ran six years, starting April 1996, and was sponsored mainly by the Deutsche Forschungsgemeinschaft, DFG, but also by the Deutsches Zentrum f r Luft-und Raumfahrt, DLR, the Physikalisch-Technische Bundesanstalt Braunschweig, PTB, and Airbus Deutschland. The papers summarise the results of the programme and cover transition mechanisms, transition prediction, transition control, natural transition and measurement techniques, transition - turbulence - separation, and visualisation issues. Three invited papers are devoted to mechanisms of turbulence production, to a general framework of stability, receptivity and control, and a forcing model for receptivity analysis. Almost every transition topic arising in subsonic and transonic flow is covered.
During the last decades completely new technologies for high speed railway vehicles have been developed. The primary goals have been to increase traction, axle load, and travelling speed, and to guarantee the safety of the passengers. However, new developments have revealed new limitations: settlement and destruction of the ballast and the subgrade lead to deterioration of the track; irregular wear of the wheels causes an increase in overall load and deterioration in passenger comfort; and damage of the running surfaces of the rail and the wheel is becoming more frequent. These problems have been investigated in the Priority Programme SPP 1015 supported by the Deutsche Forschungsgemeinschaft (DFG), with the goal of better understanding of the dynamic interaction of vehicle and track, and the long-term behavior of the components of the system. The book contains the scientific results of the programme as presented at the concluding colloquium held at University of Stuttgart, Germany, 2002.
Contained in the volume are the papers presented at an International Symposium on Advanced Technology for Design and Fabrication of Composite Materials and Structures. The Symposium was organized by Consorzio per la Ricerca e l'Educazione Permanente; Institute of Fracture and Solid Mechanics, Lehigh University, Pennsylvania USA; Dipartimento di Ingegneria Strutturale del Politecnico di Torino; and Dipartimento di Ingegneria Aeronautica e Spaziale del Politecnico di Torino. It was held at the Politecnico di Torino in Italy, May 24-28, 1993. The support from the various organizations is acknowledged as follows: * Consiglio N azionale delle Ricerche * ALENIA SP AZIO * AGUST A * CIRA * AERMACCHI * Centro Ricerche FIAT * ALENIA (formerly AERITALIA) * Collegio Costruttori Edili della Provincia di Torino As new knowledge is being accumulated on the design and fabrication of advanced composite systems in different sectors of the world, there is the need not only to exchange new ideas but also to disseminate the information from the researchers to the users. The theme of this Symposium is particularly relevant to the automobile, marine, aerospace and construction industry where the competitive edge lies on improved processing and/or manufacturing of the products. Technological advances have been and will continue to depend strongly on the development of new materials and their effective use in design. Empirical trial-and- error methods could no longer be considered economically feasible when applied to usage-specific materials such as composites.
Glare is the name given to a new material for aircraft structures developed at Delft University in the Netherlands. It consists of thin aluminium layers bonded together by adhesive containing embedded fibres and is very resistant to fatigue. This book gives the inside story of how the development of Glare took place. It took more than two decades from the first tests in Delft to the major breakthrough following the decision of Airbus to apply the material on the A380 super-jumbo. This success was achieved by a small group of people inspired by professor Boud Vogelesang, people who kept believing in the material and fought against all obstacles during the years. This book tells the story of the ups and downs and the final success of their efforts.
German Ordoliberalism and French Regulation theory, two institutionalist theories born in different national contexts, show striking convergences and complementarities. Based on an original comparison, Institutional Economics in France and Germany analyses the basic concepts, the development and the present relevance of both schools, the way they deal with the crucial methodological issue of complexity and with transformation in post-socialist Europe. It underlines the specificity and fruitfulness of these European approaches to institutional economics, often unfortunately ignored in the English-language literature. Written by leading scholars, this book is a clear presentation of both theories, with numerous illustrations and in-depth analysis of recent research developments. This theoretical, methodological and thematic comparison raises central issues in the growing field of socioeconomic and institutionalist theory.
Iteration regularization, i.e., utilization of iteration methods of any form for the stable approximate solution of ill-posed problems, is one of the most important but still insufficiently developed topics of the new theory of ill-posed problems. In this monograph, a general approach to the justification of iteration regulari zation algorithms is developed, which allows us to consider linear and nonlinear methods from unified positions. Regularization algorithms are the 'classical' iterative methods (steepest descent methods, conjugate direction methods, gradient projection methods, etc.) complemented by the stopping rule depending on level of errors in input data. They are investigated for solving linear and nonlinear operator equations in Hilbert spaces. Great attention is given to the choice of iteration index as the regularization parameter and to estimates of errors of approximate solutions. Stabilizing properties such as smoothness and shape constraints imposed on the solution are used. On the basis of these investigations, we propose and establish efficient regularization algorithms for stable numerical solution of a wide class of ill-posed problems. In particular, descriptive regularization algorithms, utilizing a priori information about the qualitative behavior of the sought solution and ensuring a substantial saving in computational costs, are considered for model and applied problems in nonlinear thermophysics. The results of calculations for important applications in various technical fields (a continuous casting, the treatment of materials and perfection of heat-protective systems using laser and composite technologies) are given."
This collection presents 49 contributions by engineers, architects, biologists, and applied mathematicians interested in deployable structures. Aerospace structures are currently at the leading edge, and this is reflected by a larger number of contributions covering the full spectrum of concepts, simulations, testing, and working systems.
Aircraft design processes require extensive work in the area of both aerodynamics and structure, fonning an environment for aeroelasticity investigations. Present and future designs of European aircraft are characterized by an ever increasing aircraft size and perfonnance. Strong weight saving requirements are met by introduction of new materials, leading to more flexible structure of the aircraft. Consequently, aeroelastic phenomena such as vortex-induced aeroelastic oscillations and moving shock waves can be predominant and may have a significant effect on the aircraft perfonnance. Hence, the ability to estimate reliable margins for aeroelastic instabilities (flutter) or dynamic loads (buffeting) is a major concern to the aircraft designer. As modern aircrafts have wing bending modes with frequencies that are low enough to influence the flight control system, demands on unsteady aerodynamics and structural analysis to predict flight control effectiveness and riding comfort for passengers are extremely high. Therefore, the aircraft industries need an improved capacity of robust, accurate and reliable prediction methods in the coupled aeroelastic, flight mechanics and loads disciplines. In particular, it is necessary to develop/improve and calibrate the numerical tools in order to predict with high level of accuracy and capability complex and non-classical aeroelastic phenomena, including aerodynamic non-linearities, such as shock waves and separation, as well as structural non-linearities, e. g. control surface free-play. Nowadays, robust methods for structural analysis and linearised unsteady aerodynamics are coupled and used by the aircraft industry to computationally clear a new design from flutter.
All typical and special modal and response analysis methods, applied within the frame of the design of spacecraft structures, are described in this book. It therefore addresses graduate students and engineers in the aerospace field.

Fully Tuned Radial Basis Function Neural Networks for Flight Control presents the use of the Radial Basis Function (RBF) neural networks for adaptive control of nonlinear systems with emphasis on flight control applications. A Lyapunov synthesis approach is used to derive the tuning rules for the RBF controller parameters in order to guarantee the stability of the closed loop system. Unlike previous methods that tune only the weights of the RBF network, this book presents the derivation of the tuning law for tuning the centers, widths, and weights of the RBF network, and compares the results with existing algorithms. It also includes a detailed review of system identification, including indirect and direct adaptive control of nonlinear systems using neural networks. Fully Tuned Radial Basis Function Neural Networks for Flight Control is an excellent resource for professionals using neural adaptive controllers for flight control applications.
This volume includes versions of papers selected from those presented at the THIESEL 2000 Conference on Thermofluidynamic Processes in Diesel Engines, held at the Universidad Politecnica de Valencia, during the period of September th th 13 to 15 , 2000. The papers are grouped into seven thematic areas: State of the Art and Prospective, Fuels for Diesel Engines, Injection System and Spray Formation, Combustion and Pollutant Formation, Modelling, Experimental Techniques, and Air Management. These areas cover most of the technologies and research strategies that may allow Light Duty and Heavy Duty Diesel engines to comply with current and forthcoming emission standards, while maintaining or improving fuel consumption. The main objectives of the conference were to bring together ideas and experience from Industry and Universities to facilitate interchange of information and to promote discussion of future research and development needs. The technical papers emphasised the use diagnostic and simulation techniques and their relationship to engineering practice and the advancement of the Diesel engine. We hope that this approach, which proved to be successful at the Conference, is reflected in this volume. We thank all those who contributed to the success of the Conference, and particularly the members of the Advisory Committee who assessed abstracts and chaired many of the technical sessions. Weare also grateful to participants who presented their work or contributed to the many discussions. Finally, the Conference benefitted from financial support from the organisations listed below and we are glad to have this opportunity to record our gratitude.
This is the second book edited with a selection of papers from the two-yearly THIESEL Conference on Thermo- and Fluid Dynamic Processes in Diesel Engines, organised by CMT-Mvtores Termicos of the Universidad Po/itecnica de Valencia, Spain. This volume includes versions of papers selected from those presented at the THIESEL 2002 Conference th held on lOth to 13 September 2002. We hope it will be the second volume of a long series reflecting the quality of the THIESEL Conference. This year, the papers are grouped in six main thematic areas: State of the Art and Prospective, Injection Systems and Spray Formation, Combustion and Emissions, Engine Modelling, Alternative Combustion Concepts and Experimental Techniques. The actual conference covered a wider scope of topics, including Air Management and Fuels for Diesel Engines and a couple of papers included reflect this variety. However, the selection of papers published here represents the most current preoccupations of Diesel engine designers, namely how to improve the combustion process using new injection strategies and alternative concepts such as the Homogeneous Charge Combustion Ignition.
This volume collects contributions to the 14th Symposium of the STAB (German Aerospace Aerodynamics Association). The association involves German scientists and engineers from universities, research establishments and industry who are doing research and project work in numerical and experimental fluid mechanics and aerodynamics, mainly for aerospace but for other applications, too. The volume gives a broad overview of ongoing work in Germany in this field.
Combustion in Piston Engines presents the technique of pressure diagnostics to measure the fuel consumption in an engine cylinder and to monitor the operation of micro-electronic systems for its control. It provides a recipe for bridging the gap between the hydrocarbon-fed combustion technology of automotive powerplants of today and electro-magnetic technologies of the future. The author proposes and introduces a model for the design of a MECC (micro-electronically controlled combustion) systems to modulate combustion in engine cylinders. This system yields significant reduction in the formation of pollutants and the consumption of fuel, so that, eventually, emissions using any clean hydrocarbon fuel will be acceptable and gas mileage could be doubled.
This volume features the contributions to the 15th Symposium of the STAB (German Aerospace Aerodynamics Association). Papers provide a broad overview of ongoing work in Germany, including high aspect ratio wings, low aspect ratio wings, bluff bodies, laminar flow control and transition, active flow control, hypersonic flows, aeroelasticity, aeroacoustics, mathematical fundamentals, numerical simulations, physical fundamentals, and facilities.
Over the past decade, the transport industry has become an increasingly popular scapegoat for polluting the environment with emissions and noise. Therefore, additional transport infrastructure investments, especially in road transport, are becoming more and more contentious. Conversely, the advocates of free trade stress the importance of transport to enhance economic growth and subsequently the standards of living. Thus, political decision makers and business people alike are facing the challenge of reconciling these conflicting ideas. Though being one of the most prominent topics in public discussion, hard facts are still rare. In order to analyze the question from a different perspective, this book sets out to combine different approaches from economics as well as business administration to stimulate scientific discourse and to support decision-makers in their efforts to ameliorate the situation. The first part of this book contributes to the empirics of the relationship between transport and economic growth, or more specifically, whether "decoupling" of transport and economic growth appears possible. For this purpose previously unavailable regional data for Italy and Germany were collected and analyzed. The results indicate that transport makes an important contribution to economic growth. Therefore, the second part of this book goes into more detail. Given the economic importance of transport and the resistance against the expansion of the transport infrastructure, it is essential to make efficient use of the already existing transportation network. For this purpose the author investigates which characteristics of transport are perceived as most important by decision makers, applying an adaptive conjoint analysis. The results show that transport quality in terms of timeliness, reliability, etc. seems to be at least as important as the monetary transport costs.
This book deals mainly with the problems associated with the contamination of groundwater by MTBE and TBA, but ETBE is also considered. The book, written by recognized specialists in the field, is organized in sections covering state-of-the-art analytical methods, including specific isotopic analysis, occurrence in the environment, transport and degradation processes, treatment technologies and human health risks.
Modern electric vehicles (EVs) are well suited to most people's general transport needs. Despite this, their adoption at a large scale has been grindingly slow. What are the reasons for this? Unlike most books which focus on the technical aspects of EV performance, this guide sets out the commercial and political barriers to their increased use and lays out the ways in which these barriers can be overcome. It begins by charting the rise of the internal combustion engine, and detailing the problems associated with it which are driving efforts to electrify transportation. It goes on to introduce readers to the main EV technologies and examines the key issue of energy storage and recharging infrastructure. The remaining chapters explore the cost-effectiveness of electric mobility, the differing adoption trajectories by which EVs may come to increase in prominence, and the way in which policy can be tailored to encourage this rise. The book covers industrialized and emerging economy contexts, the latter of which have the greatest opportunities and most urgent need to take the EV development route. Requiring no specialist engineering knowledge to understand and written in an engaging, accessible style, this is a valuable primer and resource for people in business, policy or study who are keen to understand, encourage and capitalize on the transition to electric mobility.
