A few years ago the Helmholtz Association (HGF) consisting of 15 research Institutions including the German Aerospace Center (DLR) started a network research program called 'Virtual Institutes'. The basic idea of this program was to establish research groups formed by Helmholtz research centers and universities to study and develop methods or technologies for future applications and educate young scientists. It should also enable and encourage the partners of this Virtual Institute after 3 years funding to continue their cooperation in other programs. Following this HGF request and chance the DLR Windtunnel Department of the Institute of Aerodynamics and Flow Technology took the initiative and established a network with other DLR institutes and German u- versities RWTH Aachen, University of Stuttgart and Technical University Munich. The main goal of this network was to share the experience in system analysis, ae- dynamics and material science for aerospace for improving the understanding and applicability of some key technologies for future reusable space transportation s- tems. Therefore, the virtual institute was named RESPACE (Key Technologies for Re- Usable Space Systems).

The aerospace industry increasingly relies on advanced numerical simulation tools in the early design phase. This volume provides the results of a German initiative which combines many of the CFD development activities from the German Aerospace Center (DLR), universities, and aircraft industry. Numerical algorithms for structured and hybrid Navier-Stokes solvers are presented in detail. The capabilities of the software for complex industrial applications are demonstrated.

This book introduces a dynamic, on-line fuzzy inference system. In this system membership functions and control rules are not determined until the system is applied and each output of its lookup table is calculated based on current inputs. The book describes the real-world uses of new fuzzy techniques to simplify readers' tuning processes and enhance the performance of their control systems. It further contains application examples.

From the beginnings of the International Forum on Advanced Microsystems for Automotive Application (AMAA) to the recent 11th AMAA Forum, enormous progress has been made in reducing casualties, emissions and in increasing comfort and performance. In many cases Microsystems provided key functions for this progress. This publication is a cut-out of new technological priorities in the area of microsystems-based smart devices, taking a mid-term perspective of future smart systems applications in automobiles.

Traditionally, the study of internal combustion engines operation has focused on the steady-state performance. However, the daily driving schedule of automotive and truck engines is inherently related to unsteady conditions. In fact, only a very small portion of a vehicle's operating pattern is true steady-state, e. g. , when cruising on a motorway. Moreover, the most critical conditions encountered by industrial or marine engines are met during transients too. Unfortunately, the transient operation of turbocharged diesel engines has been associated with slow acceleration rate, hence poor driveability, and overshoot in particulate, gaseous and noise emissions. Despite the relatively large number of published papers, this very important subject has been treated in the past scarcely and only segmentally as regards reference books. Merely two chapters, one in the book Turbocharging the Internal Combustion Engine by N. Watson and M. S. Janota (McMillan Press, 1982) and another one written by D. E. Winterbone in the book The Thermodynamics and Gas Dynamics of Internal Combustion Engines, Vol. II edited by J. H. Horlock and D. E. Winterbone (Clarendon Press, 1986) are dedicated to transient operation. Both books, now out of print, were published a long time ago. Then, it seems reasonable to try to expand on these pioneering works, taking into account the recent technological advances and particularly the global concern about environmental pollution, which has intensified the research on transient (diesel) engine operation, typically through the Transient Cycles certification of new vehicles.

The book focuses on the fluid dynamics of cavitation with special reference to high power density turbopumps, where it represents the major source of performance and life degradation. While covering the more fundamental aspects of cavitation and the main kinds of cavitating flows, there is focus on the hydrodynamics and instabilities of cavitating turbopumps. The book also illustrates the alternative approaches for modeling and engineering simulation of cavitating flows.

The 26th International Symposium on Shock Waves in G ttingen, Germany was jointly organised by the German Aerospace Centre DLR and the French-German Research Institute of Saint Louis ISL. The year 2007 marked the 50th anniversary of the Symposium, which first took place in 1957 in Boston and has since become an internationally acclaimed series of meetings for the wider Shock Wave Community. The ISSW26 focused on the following areas: Shock Propagation and Reflection, Detonation and Combustion, Hypersonic Flow, Shock Boundary Layer Interaction, Numerical Methods, Medical, Biological and Industrial Applications, Richtmyer Meshkov Instability, Blast Waves, Chemically Reacting Flows, Diagnostics, Facilities, Flow Visualisation, Ignition, Impact and Compaction, Multiphase Flow, Nozzles Flows, Plasmas and Propulsion. The two Volumes contain the papers presented at the symposium and serve as a reference for the participants of the ISSW 26 and individuals interested in these fields.

Flight mechanics is the application of Newton's laws to the study of vehicle trajectories (performance), stability, and aerodynamic control. This volume details the derivation of analytical solutions of airplane flight mechanics problems associated with flight in a vertical plane.

It covers trajectory analysis, stability, and control. In addition, the volume presents algorithms for calculating lift, drag, pitching moment, and stability derivatives. Throughout, a subsonic business jet is used as an example for the calculations presented in the book.

The last two decades have brought two important developments for aeroth- modynamics. One is that airbreathing hypersonic flight became the topic of technology programmes and extended system studies. The other is the emergence and maturing of the discrete numerical methods of aerodyn- ics/aerothermodynamics complementary to the ground-simulation facilities, with the parallel enormous growth of computer power. Airbreathing hypersonic flight vehicles are, in contrast to aeroassisted re-entry vehicles, drag sensitive. They have, further, highly integrated lift and propulsion systems. This means that viscous eflFects, like boundary-layer development, laminar-turbulent transition, to a certain degree also strong interaction phenomena, are much more important for such vehicles than for re-entry vehicles. This holds also for the thermal state of the surface and thermal surface effects, concerning viscous and thermo-chemical phenomena (more important for re-entry vehicles) at and near the wall. The discrete numerical methods of aerodynamics/aerothermodynamics permit now - what was twenty years ago not imaginable - the simulation of high speed flows past real flight vehicle configurations with thermo-chemical and viscous effects, the description of the latter being still handicapped by in sufficient flow-physics models. The benefits of numerical simulation for flight vehicle design are enormous: much improved aerodynamic shape definition and optimization, provision of accurate and reliable aerodynamic data, and highly accurate determination of thermal and mechanical loads. Truly mul- disciplinary design and optimization methods regarding the layout of thermal protection systems, all kinds of aero-servoelasticity problems of the airframe, et cetera, begin now to emerge."

Simplified fracture mechanics based assessment methods are widely used by the industry to determine the structural integrity significance of postulated cracks, manufacturing flaws, service-induced cracking or suspected degradation of engineering components under normal and abnormal service loads. In many cases, welded joints are the regions most likely to contain original fabrication defects or cracks initiating and growing during service operation. Various procedures provide upper bound residual stress profiles for various classes of welded joints that can be used in fracture assessments, but these often give very conservative results. Recently, the option to use more realistic profiles has been adopted, but only where such profiles are based on finite element residual stress simulations supported by detailed residual stress measurements. Rapid advances in the capability of residual stress measurement techniques, such as the contour and deep hole drilling techniques as well as the neutron and synchrotron X-ray diffraction methods, now readily allow residual stresses and strains to be mapped on defined planes within a structure. The contents of this book have been grouped into three topic areas covering theoretical /numerical and experimental analyses of residual stress and its effects on fatigue and fracture.

There is a growing interest in applying model predictive control techniques to automotive systems, often for different reasons: the simple handling of constraints, the easy use of preview information or the flexibility of the method. Some long-standing problems with this approach, like the high computational burden, have been solved or at least substantially mitigated.

Even so, many issues remain to be elucidated, and, at the same time, papers and results in the increasingly rich literature are not always comparable.

Against this background, the proceedings of the Automotive Model Predictive Control: Models, Methods and Applications workshop investigates whether constrained predictive control is reasonable in automotive control and what is necessary for its application. The workshop, held at the University of Linz on 9th 10th February 2009 brought together workers from academia and industry from three key automotive branches: modeling, control and the application. The workshop included three keynote presentations, each of them contributing to the solution of an essential question.

Which problems in automotive applications need constrained optimal control?

Models of emissions for modern engines for model based control?

Industrial methods and requirements for control schemes?

The results of testing control strategies on a dynamical engine test bench give a feeling for the necessary computing power, the model plant mismatch, etc. and thus for the real application of control laws in production cars."

Spaceflight Life Support and Biospherics is the introduction to space life support systems and artificial ecosystems that has so far been lacking. It is a source of information for everyone involved in the life support system design and development process - engineers, scientists, and students - as well as all those who are simply interested in this existing discipline. The structure of this book is such that it gives step-by-step answers to the basic questions concerning life support systems on any scale - from small microbial systems to the Earth's biosphere: Why life support system development and biosphere research? How does our natural life support system, the biosphere, work? What are the environmental conditions for life support systems in space? What are the fundamental terms and requirements of life support? Which physicochemical life support subsystems currently exist? Which are the potential bioregenerative life support technologies of the future? What are life support systems of future planetary habitats going to look like? What are the experiences of the largest artificial ecosystem - Biosphere 2? What are the potential terrestrial benefits of life support development? GBP/LISTGBP

Airborne Vehicle Guidance and Control Systems is a broad and wide- angled engineering and technological area for research, and continues to be important not only in military defense systems but also in industrial process control and in commercial transportation networks such as various Global Positioning Systems (GPS). The book fills a long-standing gap in the literature. The author is retired from the Air Force Institute and received the Air Force's Outstanding Civilian Career Service Award.

This book presents the latest developments in structural dynamics with particular emphasis on the formulation of equations of motion by finite element methods and their solution using microcomputers. The book discusses the use of frequency-dependent shape functions for realistic finite element modelling, as opposed to the approximate conventional shape functions. A useful feature of the book in handling the forced vibration problem is the separation of the solution into two parts; the steady state and transient. Advanced topics such as substructure and synthesis are viewed in a modern unified manner. A complete listing of the finite element programme NATVIB used is given.

Stefan Baerisch applies a combination of feature modelling and code generation, for which he uses a model-driven approach, in order to facilitate the design of tests by non-programmers. This combination of modelling and code generation allows for a more integrated and more efficient testing process.

The aeronautics industry is presently aiming for faster design cycles and shorter time to market of new aircraft. It is looking at the same time for improved aerodynamic performance, for evident competitive reasons. Advanced, computer based design systems, including fast and reliable numerical flow solvers, have been developed in the last decade including new turbulence models. On the experimental side, measurement techniques in general have also been improved significantly, however the data evaluation process remains still very time consuming, and unsteady effects and turbulence are often not being captured with sufficient accuracy and detail. The development of Particle Image Velocimetry (PIV) has helped to improve the analysis of the flow fields. After investigations in laboratory scale wind tunnels, a joint initiative on PIV research, by the European Aerospace Research Establishments, within GARTEUR have enabled a wide breakthrough of this new technology in Europe. Within the Research Framework Program of the European Union, the joint research project EUROPIV aimed to apply PIV technology to problems of industrial interest.

Andreas Riener studies the influence of implicit interaction using vibro-tactile actuators as additional sensory channels for car-driver feedback and pressure sensor arrays for implicit information transmission from the driver toward the vehicle. The results of his experiments suggest the use of both vibro-tactile notifications and pressure sensor images to improve vehicle handling performance and to decrease the driver s cognitive workload.

Almost 50 years after the launch of Sputnik, the diversity and criticality of the technology and applications already in place to exploit the high-frontier is impressive. And it is no exaggeration to state that a precondition for meeting human needs, coping with environmental problems, and maintaining security is the successful exploitation of space. Yet no one overview exists to document what we have so far done, and soon plan to accomplish, to utilize the near-Earth space environment. Utilization of Space aims to serve as an authoritative overview for professionals and interested laymen by explaining scientific space utilisation, commercial and entrepreneurial issues, and technological applications. The chapters are written by leading specialists in the respective fields and on a level comprehensible to an educated, but not necessarily technically-trained, reader. Enhanced by informative color illustrations, it is intended not only to transmit useful and timely information to readers, but also to share with them the fascination attached to space activities experienced by those actively engaged in them.

This book was born from curiosity. To begin with, it was the curiosity of an economist who studied in the 60's in an environment which has subsequently developed from national into global economics. Who has to recognize that politicians, scholars and large segments of society oblivious to supranational authorities and e- nomic globalization forces continue to labour under the notion that they are still fully autonomous and sovereign when shaping national economic policy. And pretend as though their own national state were still the "m- ter in its own house" that despite unbridled market economics could c- tinue to dictate to the economy and companies how to live and in which "rooms." All that has become fiction. The laws of globalization diminish the - noeuvring space for shaping national economic policy. Even if many folks today don't want to hear it: The issue is no longer achieving what is soc- politically desirable for the own society but rather the optimal adaptation of society and social benefits to the politically practicable.

This monograph presents a novel concept of a mobile robot, which is a single-wheel, gyroscopically stabilized robot. The robot is balanced by a spinning wheel attached through a two-link manipulator at the wheel bearing, and actuated by a drive motor. This configuration conveys significant advantages including insensitivity to attitude disturbances, high maneuverability, low rolling resistance, ability to recover from falls, and amphibious capability for potential applications on both land and water. This book focuses on the dynamics and control aspects, including modeling, model-based control, learning-based control, and shared control with human operators. This novel mobile robot concept opens up the science of dynamically stable systems with a single wheel configuration. The book also presents considerations in concept, design implementations, and kinematics modeling, as well as experimental results from various algorithms and cases. The system is a nonholonomic, underactuated, and highly nonlinear system, so this book is appropriate for scientists and engineers with interests in mobile robot, dynamics and control, as a research reference and postgraduate textbook.

The general theme of the CE2009 Conference is the recognised requirement for advancements in Concurrent Engineering (CE) with a global perspective for competitive enterprise, economy and ecology. CE appeared in the '80s as the concept of parallel performing engineering design activities and the integration of all related processes. This concept is based on the general assumption that different components of the product life cycle should be considered together and relatively early. The main goal of CE is to make processes more efficient and more resistant to errors.

Since then the whole CE approach has evolved into different forms with different names and has become omnipresent. The industrial presence of CE differs from well established corporation implementations to SME applications. The last twenty years have brought many changes to the organization of product design and manufacturing: engineers have developed narrower specializations; engineers have developed a global presence; engineers work in firms which are final producers or suppliers; sometimes firms create alliances; engineers cooperate and collaborate; and they use different methods and tools to support their engineering activities. As a result the CE approach supports engineers in many ways.

The role of information systems in CE has always been treated as very important. First methodologies and tools were concentrated on offering the possibility to contact people and processes, to make the right information and knowledge available at the right time. The presence of computer tools in CE is treated as standard.

If one looks now at what is going on and at how many different issues are important in design, manufacturing, supply, distribution, etc., one will understand why the context of CE is so rich and so complicated, why there are so many CE specializations and why the main topic of the CE2009 Conference is of great relevance. The plurality of CE specializations mentioned above was reflected in the following CE2009 Conference tracks: Systems Engineering, PLM, Advanced Manufacture, Product Design, Mass Customization, Lean Thinking, Design for Sustainability, Customer Value, Environmental Impact, Knowledge Engineering, SCM, Concurrent System Architecturing, Collaborative Engineering, Web Technologies, Standards, Digital Manufacture, Service Solutions, Purchasing/Procurement, Emotion Engineering. Apart from the above tracks the conference also has seven special sessions in RFID, Collaborative Product Development, Multi-disciplinary Design and Optimization, Design Knowledge Utilization, Competitive Supply Chain Performance, Value Engineering, and Competitive Design.

The proceedings contain 94 papers, demonstrating the multitude of different perspectives contained in this volume. There are papers which are theoretic and conceptual, as well as papers which have very strong industrial roots. There are also very detailed, highly specialized paper, which are closely linked to specific industrial case studies. The reader will also find papers which are based on real processes, but which operate on abstract models and which offer a bridge between industrial reality and academic research.

CE does not develop equally in each area; the direction of development depends on many factors. The content of this volume reflects the variety of issues in today's CE methods and phenomena; consequently, readers will be able to build their own view of the present problems and methods involved in CE.
