Exploiting the properties of piezoelectric materials to minimize vibration in rotor-blade actuators, this book demonstrates the potential of smart helicopter rotors to achieve the smoothness of ride associated with jet-engined, fixed-wing aircraft. Vibration control is effected using the concepts of trailing-edge flaps and active-twist. The authors' optimization-based approach shows the advantage of multiple trailing-edge flaps and algorithms for full-authority control of dual trailing-edge-flap actuators are presented. Hysteresis nonlinearity in piezoelectric stack actuators is highlighted and compensated by use of another algorithm. The idea of response surfaces provides for optimal placement of trailing-edge flaps. The concept of active twist involves the employment of piezoelectrically induced shear actuation in rotating beams. Shear is then demonstrated for a thin-walled aerofoil-section rotor blade under feedback-control vibration minimization. Active twist is shown to be significant in reducing vibration caused by dynamic stall. The exposition of ideas, materials and algorithms in this monograph is supported by extensive reporting of results from numerical simulations of smart helicopter rotors. This monograph will be a valuable source of reference for researchers and engineers with backgrounds in aerospace, mechanical and electrical engineering interested in smart materials and vibration control.

This book systematizes recent research work on variable-structure control. It is self-contained, presenting necessary mathematical preliminaries so that the theoretical developments can be easily understood by a broad readership. The text begins with an introduction to the fundamental ideas of variable-structure control pertinent to their application in complex nonlinear systems. In the core of the book, the authors lay out an approach, suitable for a large class of systems, that deals with system uncertainties with nonlinear bounds. Its treatment of complex systems in which limited measurement information is available makes the results developed convenient to implement. Various case-study applications are described, from aerospace, through power systems to river pollution control with supporting simulations to aid the transition from mathematical theory to engineering practicalities. The book addresses systems with nonlinearities, time delays and interconnections and considers issues such as stabilization, observer design, and fault detection and isolation. It makes extensive use of numerical and practical examples to render its ideas more readily absorbed. Variable-Structure Control of Complex Systems will be of interest to academic researchers studying control theory and its application in nonlinear, time-delayed an modular large-scale systems; the robustness of its approach will also be attractive to control engineers working in industries associate with aerospace, electrical and mechanical engineering.

This book presents the most serious and comprehensive study, by far, of American public perceptions about the meaning of space exploration, analyzing vast troves of questionnaire data collected by many researchers and polling firms over a span of six decades and anchored in influential social science theories.It doesn't simply report the percentages who held various opinions, but employs sophisticated statistical techniques to answer profound questions and achieve fresh discoveries.

Both the Bush and the Obama administrations have cut back severely on fundamental research in space science and engineering. Understanding better what space exploration means for citizens can contribute to charting a feasible but progressive course. Since the end of the Space Race between the US and the USSR, social scientists have almost completely ignored space exploration as a topic for serious analysis and this book seeks to revive that kind of contribution.

The author communicates the insights in a lucid style, not only intelligible but interesting to readers from a variety of backgrounds."

An emerging trend in the automobile industry is its convergence with information technology (IT). Indeed, it has been estimated that almost 90% of new automobile technologies involve IT in some form. "Smart" driving technologies that improve safety as well as "green" fuel technologies are quite representative of the convergence between IT and automobiles. The smart driving technologies include three key elements: sensing of driving environments, detection of objects and potential hazards and the generation of driving control signals including warning signals.

Although radar-based systems are primarily used for sensing the driving environments, the camera has gained importance in advanced driver assistance systems (ADAS).

This book covers system-on-a-chip (SoC) designs including both algorithms and hardware related with image sensing and object detection by using the camera for smart driving systems. It introduces a variety of algorithms such as lens correction, super resolution, image enhancement and object detections from the images captured by low-cost vehicle camera. This is followed by implementation issues such as SoC architecture, hardware accelerator, software development environment and reliability techniques for automobile vision systems.

This book is aimed for the new and practicing engineers in automotive and chip-design industries to provide some overall guidelines for the development of automotive vision systems.

It will also help graduate students understand and get started for the research work in this field."

The auto industry is facing tough competition and severe economic constraints. Their products need to be designed "right the first time" with the right combinations of features that not only satisfy the customers but continually please and delight them by providing increased functionality, comfort, convenience, safety, and craftsmanship. Based on the author's forty plus years of experience as a human factors researcher, engineer, manager, and teacher who has conducted numerous studies and analyses, Ergonomics in the Automotive Design Process covers the entire range of ergonomics issues involved in designing a car or truck and provides evaluation techniques to avoid costly mistakes and assure high customer satisfaction. The book begins with the definitions and goals of ergonomics, historic background, and ergonomics approaches. It covers human characteristics, capabilities, and limitations considered in vehicle design in key areas such as anthropometry, biomechanics, and human information processing. It then examines how the driver and the occupants are positioned in the vehicle space and how package drawings and/or computer-aided design models are created from key vehicle dimensions used in the automobile industry. The author describes design tools used in the industry for occupant packaging, driver vision, and applications of other psychophysical methods. He covers important driver information processing concepts and models and driver error categories to understand key considerations and principles used in designing controls, displays, and their usages, including current issues related to driver workload and driver distractions. The author has included only the topics and materials that he found to be useful in designing car and truck products and concentrated on the ergonomic issues generally discussed in the automotive design studios and product development teams. He distills the information needed to be a member of an automotive product development team and create an ergonomically superior vehicle.

This book describes current, competitive coating technologies for vehicles. The authors detail how these technologies impact energy efficiency in engines and with increased use of lightweight materials and by varying coatings applications can resolve wear problems, resulting in the increased lifecycle of dies and other vehicle components.

This book highlights the current challenges for engineers involved in product development and the associated changes in procedure they make necessary. Methods for systematically analyzing the requirements for safety and security mechanisms are described using examples of how they are implemented in software and hardware, and how their effectiveness can be demonstrated in terms of functional and design safety are discussed. Given today's new E-mobility and automated driving approaches, new challenges are arising and further issues concerning "Road Vehicle Safety" and "Road Traffic Safety" have to be resolved. To address the growing complexity of vehicle functions, as well as the increasing need to accommodate interdisciplinary project teams, previous development approaches now have to be reconsidered, and system engineering approaches and proven management systems need to be supplemented or wholly redefined. The book presents a continuous system development process, starting with the basic requirements of quality management and continuing until the release of a vehicle and its components for road use. Attention is paid to the necessary definition of the respective development item, the threat-, hazard- and risk analysis, safety concepts and their relation to architecture development, while the book also addresses the aspects of product realization in mechanics, electronics and software as well as for subsequent testing, verification, integration and validation phases. In November 2011, requirements for the Functional Safety (FuSa) of road vehicles were first published in ISO 26262. The processes and methods described here are intended to show developers how vehicle systems can be implemented according to ISO 26262, so that their compliance with the relevant standards can be demonstrated as part of a safety case, including audits, reviews and assessments.

Increasing concern with fuel consumption leads to widespread interest in lightweight structures for transportation vehicles.

A tour of over 30 minor harbours around the coasts of southwest Britain from Lyme Bay to the River Severn. Illustrated with evocative colour photography, Dag Pike's narrative brings to life a contrasting collection of small historic harbours, which although infrequently visited have a fascinating story to tell. 'Hidden Harbours of Southwest Britain' aims to paint a picture of what harbours were like in the past and what they are like now. They can make an interesting alternative for visiting yachtsmen looking for somewhere off the beaten track to visit and explore, perhaps by small tenders. They can tempt visitors looking to trace the industrial archaeology of harbours and the reasons for its rise and decline, or walkers along the coastal paths. Many of the harbours were built to last and they can be rich in history and rewarding to visit both by land and sea. Dag Pike has 60 years of experience in a wide variety of ships and boats having worked with Trinity House on their lighthouse tenders and with the RNLI as an Inspector of Lifeboats. He has raced offshore powerboats, sailed competitively and set many long distance records, and has cruised extensively around the coasts on both power and sail yachts. He holds a Master's certificate and a Yachtmaster Ocean. He has written 36 books including his autobiography and writes for many yachting magazines around the world. He now spends part of the year living in Cornwall and sails in the Falmouth Working Boats. "This is a real gem of a book for sailor and landlubber alike. Dag's choice of photography is particularly relevant, the page layout with the aerial topography depicting the harbour is well thought out. Thoroughly recommended". - Nautical Magazine

Mobility is an essential part of our lives. The ability to move freely is central to meeting our social and economic needs. For this reason we have embraced the car over the past century perhaps more than any other technology or consumer pr- uct. Today there are around 900 million vehicles on the world`s roads with another 60,000,000 new vehicles produced each year worldwide. The scale of the auto- tive industry is significant and far reaching. For example, it is estimated that around two thirds of world`s oil output goes to transportation whereby road - hicles alone consume around 40% of the world`s rubber and 25% of the world`s glass, with the consumption of raw materials and other resources further growing due to the rapid development of the automotive sector in China, India, Thailand and Mexico. Transportation accounts for around 25% of greenhouse emissions worldwide, whereby 90% of transport related emissions come from road vehicles, predominantly cars. Clearly, current levels of consumption and emissions are - sustainable. This in turn suggests that mobility as we know it, based on the tra- tional vehicle technology and existing production and consumer practices, is - sustainable. The challenge of developing new sustainable approaches to mobility confronts industries and our societies in general. The concept of sustainable mobility is m- tidimensional and the challenge of achieving it is quite complex.

At this workshop, leading experts in research, industry and academia from around the world met to share their ideas and approaches on ATM/CNS related topics.

Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes.

Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

Viscous flow is treated usually in the frame of boundary-layer theory and as two-dimensional flow. Books on boundary layers give at most the describing equations for three-dimensional boundary layers, and solutions often only for some special cases.

This book provides basic principles and theoretical foundations regarding three-dimensional attached viscous flow. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers. This wider scope is necessary in view of the theoretical and practical problems to be mastered in practice.

The topics are weak, strong, and global interaction, the locality principle, properties of three-dimensional viscous flow, thermal surface effects, characteristic properties, wall compatibility conditions, connections between inviscid and viscous flow, flow topology, quasi-one- and two-dimensional flows, laminar-turbulent transition and turbulence.

Though the primary flight speed range is that of civil air transport vehicles, flows past other flying vehicles up to hypersonic speeds are also considered. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers, as this wider scope is necessary in view of the theoretical and practical problems that have to be overcome in practice.

The specific topics covered include weak, strong, and global interaction; the locality principle; properties of three-dimensional viscous flows; thermal surface effects; characteristic properties; wall compatibility conditions; connections between inviscid and viscous flows; flow topology; quasi-one- and two-dimensional flows; laminar-turbulent transition; and turbulence. Detailed discussions of examples illustrate these topics and the relevant phenomena encountered in three-dimensional viscous flows. The full governing equations, reference-temperature relations for qualitative considerations and estimations of flow properties, and coordinates for fuselages and wings are also provided. Sample problems with solutions allow readers to test their understanding.
