This book introduces a comprehensive and mathematically rigorous controller design for families of nonlinear systems with time-varying parameters and unstructured uncertainties. Although the presented methodology is general, the specific family of systems considered is the latest, NextGen, unconventional fixed-wing unmanned aircraft with circulation control or morphing wings, or a combination of both. The approach considers various sources of model and parameter uncertainty, while the controller design depends not on a nominal plant model, but instead on a family of admissible plants. In contrast to existing controller designs that consider multiple models and multiple controllers, the proposed approach is based on the 'one controller fits all models' within the unstructured uncertainty interval. The book presents a modeling-based analysis and synthesis approach with additive uncertainty weighting functions for accurate realization of the candidate systems. This differs significantly from existing designs in that it is capable of handling time-varying characteristics. This research monograph is suitable for scientists, engineers, researchers and graduate students with a background in control system theory who are interested in complex engineering nonlinear systems.

Nimrod Boys is a complementary book to Nimrod Rise and Fall from acclaimed author Tony Blackman. It is a collection of over twenty first-hand accounts of operating the Hawker Siddeley Nimrod - an aircraft which served at the forefront of the Cold War. As the first jet-powered maritime aircraft, it could reach critical points for rescues or for operational requirements in rapid time. Its outstanding navigation and electronics systems also allowed the Nimrod to be a first-class machine in anti-submarine warfare. The book focuses on the Nimrod's UK-based and worldwide operations. With detailed accounts of the Nimrod's role during the Falklands Campaign and in later conflicts such as the First Gulf War to modern-day anti-drug smuggling operations in the Caribbean. There are also descriptions of the Nimrod's achievements in the International Fincastle Competition - where RAF squadrons competed against counterparts from Australia, Canada and New Zealand. With a variety of perspectives on Nimrod crew life, including from a female air electronic operator, readers will find dramatic, engaging and occasionally humorous stories. One flight test observer also reflects on the cancelled Nimrod MR4 project. Nimrod Boys written by Tony Blackman with Joe Kennedy and with a foreword by AVM Andrew Roberts is more than worthy addition to the celebrated Boys series.

'The text is well written and supported by clear and useful illustrations. This would be a useful textbook for postgraduate or advanced undergraduate studies and would also make a good introductory text for engineers moving into the field. The literature survey and bibliography provide a useful starting point for further study.'The Aeronautical JournalActive Control of Aircraft Cabin Noise provides a bridge to fill the gap between robust control theory and practical applications of active noise control systems in aircraft cabin. Both the possibilities and limitations of structural solutions to enhance aircraft cabin comfort by reducing interior noise are discussed supported by a wide range of topics in engineering, from finite element modeling to multichannel adaptive feed-forward control, usually dealt separately in the literature. In addition, experimental noise attenuation results with passengers' subjective perceptions predicting the effects of cabin noise on comfort assessments is examined. Theoretical and experimental research is detailed enough to capture the interest of the non-expert in engineering who wishes to have an overview of some of the active noise control applications in aircraft. This book may be used as an advanced textbook by graduate and undergraduate students in aeronautical engineering, and would be an authoritative resource book for research into the subject.

Contemporary engineering design is heavily based on computer simulations. Accurate, high-fidelity simulations are used not only for design verification but, even more importantly, to adjust parameters of the system to have it meet given performance requirements. Unfortunately, accurate simulations are often computationally very expensive with evaluation times as long as hours or even days per design, making design automation using conventional methods impractical. These and other problems can be alleviated by the development and employment of so-called surrogates that reliably represent the expensive, simulation-based model of the system or device of interest but they are much more reasonable and analytically tractable.

This volume features surrogate-based modeling and optimization techniques, and their applications for solving difficult and computationally expensive engineering design problems. It begins bypresentingthe basic concepts and formulations of the surrogate-based modeling and optimization paradigm and thendiscusses relevant modeling techniques, optimization algorithms and design procedures, as well as state-of-the-art developments. The chapters are self-contained with basic concepts and formulations along with applications and examples. The book will be useful toresearchers in engineering and mathematics, in particular those who employ computationally heavy simulations in their design work.

The Space Shuttle tells the story of NASA's amazing Space Shuttle program and its 140 space flights (135 missions, plus five Approach and Landing Tests) in a uniquely designed and covetable way. The Space Shuttle program's first free flight test was taken on August 12, 1977. Its first official mission was launched on April 12, 1981. Its final mission and flight was taken on July 8, 2011. The program's six orbiter vehicles are Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. Each mission has its own fascinating story, and The Space Shuttle retells these stories, in chronological order, through incredible photos taken by NASA photojournalists, fine art photographers, and the astronauts themselves. Each image is accompanied by a short text that includes quick facts such as crew members, launch date, and landing date, as well as a short overview of highlights and purpose. For example, STS-78's mission was to study circadian rhythms in space; STS-41G's mission was to take photographs in-flight, seen in the IMAX movie The Dream Is Alive; and famously, the first untethered space walk, taken by astronaut Bruce McCandless on STS-41B using a self-propelled backpack unit (called a Man Maneuvering Unit [MMU]), allowed astronauts to capture satellites for retrieval and repair and for the planned construction of what became the International Space Station (ISS). Prior to this mission, astronauts were attached to the shuttle with safety lines. The photo of McCandless floating above Earth's surface is one of the most celebrated and famous space photographs ever. These are just a few of the 140 stories Miller tells in this beautiful volume.

While international negotiations to reduce greenhouse gas (GHG) emissions have been less than satisfactory, there is a presumption that a significant level of multi-lateral commitment will be realized at some point. International air and marine travel have been left to one side in past talks because the pursuit of agreement proceeds on the basis of commitment by sovereign nations and the effects of these specific commercial activities are, by their nature, difficult to corral and assign to specific national jurisdictions. However, air travel is increasing and, unless something is done, emissions from this segment of our world economy will form a progressively larger percentage of the total, especially as emissions fall in other activities. This book focuses on fuel. The aim is to provide background in technical and policy terms, from the broadest reliable sources of information available, for the necessary discourse on society's reaction to the evolving aviation emissions profile. It considers what policy has been, why and how commercial air travel is committed to its current liquid fuel, how that fuel can be made without using fossil-source materials, and the barriers to change. It also advances some elements of policy remedies that make sense in providing an environmentally and economically sound way forward in a context that comprehends a more complete vision of sustainability than 'renewable fuels' traditionally have. The goal of Will Sustainability Fly? is to broaden and contextualize the knowledge resource available to academics, policy makers, air industry leaders and stakeholders, and interested members of the public.

This book reports on the German research initiative AeroStruct, a three-year collaborative project between universities and the aircraft industry. It describes the development of an integrated multidisciplinary simulation environment for aircraft analysis and optimization using high-fidelity methods. This system is able to run at a high level of automatism, thus representing a step forward with respect to previous ones. Its special features are: a CAD description that is independent from the disciplines involved, an automated CFD mesh generation and an automated structure model generation including a sizing process. The book also reports on test cases by both industrial partners and DLR demonstrating the advantages of the new environment and its suitability for the industry. These results were also discussed during the AeroStruct closing Symposium, which took place on 13-14 October 2015 at the DLR in Braunschweig, Germany. The book provides expert readers with a timely report on multidisciplinary aircraft design and optimization. Thanks to a good balance between theory and practice, it is expected to address an audience of both academics and professional, and to offer them new ideas for future research and development.

The investigation and modelling of aviation accident causation is dominated by linear models. Aviation is, however, a complex system and as such suffers from being artificially manipulated into non-complex models and methods. This book addresses this issue by developing a new approach to investigating aviation accident causation through information networks. These networks centralise communication and the flow of information as key indicators of a system's health and risk. This holistic approach focuses on the system environment, the activity that takes place within it, the strategies used to conduct this activity, the way in which the constituent parts of the system (both human and non-human) interact and the behaviour required. Each stage of this book identifies and expands upon the potential of the information network approach, maintaining firm focus on the overall health of a system. The book's new model offers many potential developments and some key areas are studied in this research. Through the centralisation of barriers and information nodes the method can be applied to almost any situation. The application of Bayesian mathematics to historical data populations provides scope for studying error migration and barrier manipulation. The book also provides application of these predictions to a flight simulator study for the purposes of validation. Beyond this it also discusses the applicability of the approach to industry. Through working with a legacy airline the methods discussed are used as the basis for a new and prospective safety management system.

This book presents a methodology for assessing environmental safety in civil aviation. The methodology allows the comparison of different technological processes and evaluates their impact on the environment. At the same time, the medical and demographic indicators for ecologically unfavorable territories are compared with similar indicators in the control (background) territories in the same climatic and geographical zones. This book contains methodological recommendations for the creation of the system for ecology safety in the organizational structures of civil aviation. This book is useful to a wide audience-students of aviation, lecturers, as well as specialists in the field of ecology and those involved in ensuring the necessary ecology requirements at aviation enterprises.

Computer simulations is a fundamental tool of the design process in many engineering disciplines including aerospace engineering. However, although high-fidelity numerical models are accurate, they can be computationally expensive with evaluation time for a single design as long as hours, days or even weeks. Simulation-driven design using conventional optimization techniques may be therefore prohibitive.This book explores the alternative: performing computationally efficient design using surrogate-based optimization, where the high-fidelity model is replaced by its computationally cheap but still reasonably accurate representation: a surrogate. The emphasis is on physics-based surrogates. Application-wise, the focus is on aerodynamics and the methods and techniques described in the book are demonstrated using aerodynamic shape optimization cases. Applications in other engineering fields are also demonstrated.State-of-the-art techniques and a depth of coverage never published before make this a unique and essential book for all researchers working in aerospace and other engineering areas and dealing with optimization, computationally expensive design problems, and simulation-driven design.

Designing Future-Oriented Airline Businesses is the eighth Ashgate book by Nawal K. Taneja to address the ongoing challenges and opportunities facing all generations of airlines. Firstly, it challenges and encourages airline managements to take a deeper dive into new ways of doing business. Secondly, it provides a framework for identifying and developing strategies and capabilities, as well as executing them efficiently and effectively, to change the focus from cost reduction to revenue enhancement and from competitive advantage to comparative advantage. Based on the author's own extensive experience and ongoing work in the global airline industry, as well as through a synthesis of leading business practices both inside and outside of the industry, Designing Future-Oriented Airline Businesses sets out to demystify numerous concepts being discussed within the airline industry and to facilitate managements to identify and articulate the boundaries of their business models. It provides material from which managements can set about answering the key questions, especially with respect to strategies, capabilities and execution, and pursue an effective redesign of their business. As with the author's previous books, the primary audience is senior-level practitioners of differing generations of airlines worldwide as well as related businesses. The material presented continues to be at a pragmatic level, not an academic exercise, to lead managements to ask themselves and their teams some critical thought-provoking questions.

Air transport in the Asia Pacific has undergone significant transformation in the last three decades. What was once a region in the shadow of larger and more prosperous continents such as North America and Europe is now at the forefront of expansion in commercial air-service networks, frequency and capacity, and the overall growth in the contribution of air transport to economies on regional and, in many cases, individual country levels. Despite this, it represents an area that is generally under-represented in the commercial air-transport academic literature. Air Transport in the Asia Pacific seeks to fill this gap. Against this context, the aim of the volume is to offer a contemporary snapshot of current academic research into commercial air transport in the Asia Pacific. While one volume cannot realistically address the complete range of identifiable issues, this book provides timely, specific and research-based studies authored by leading academics and practitioners.

This book discusses the recent advances in aircraft design methodologies. It provides an overview of topics such as shape optimization, robust design and aeroelasticity, focusing on fluid-structure numerical methodologies to address static and dynamic aeroelastic problems. It demonstrates that the capability to evaluate the interaction between aerodynamics, inertia and elastic forces is important to avoid drag penalties, control system efficiency loss and generation of potentially dangerous phenomena, such as divergence, control reversal and flutter. The book particularly highlights the advances in "high fidelity" CFD-CSM coupling, describing the latest experimental research to validate the numerical fluid-structure interaction analysis methodologies resulting from the EU-funded RBF4AERO and RIBES projects.

The goals of the 10th International Space Conference on Protection of Materials and Structures from Space Environment ICPMSE-10J, since its inception in 1992, have been to facilitate exchanges between members of the various engineering and science disciplines involved in the development of space materials, including aspects of LEO, GEO and Deep Space environments, ground-based qualification, and in-flight experiments and lessons learned from operational vehicles that are closely interrelated to disciplines of the atmospheric sciences, solar-terrestrial interactions and space life sciences.

The knowledge of environmental conditions on and around the Moon, Mars, Venus and the low Earth orbit as well as other possible candidates for landing such as asteroids have become an important issue, and protecting both hardware and human life from the effects of space environments has taken on a new meaning in light of the increased interest in space travel and colonization of other planets.

And while many material experiments have been carried out on the ground and in open space in the last 50 years (LDEF, MEEP, SARE, MISSE, AOP, DSPSE, ESEM, EURECA, HST, MDIM, MIS, MPID, MPAC and SEED), many questions regarding the environmental impact of space on materials remain either poorly understood or unanswered. The coming generations of scientists will have to continue this work and tackle new challenges, continuing to build the level of confidence humans will need to continue the colonization of space. It is hoped that the proceedings of the ICPMSE-10J presented in this book will constitute a small contribution to doing so."

Effective radio communication between ATC and pilots has long been recognized as an important element of aviation safety. In recognition of the role miscommunications play in aviation incidents and accidents, the International Civil Aviation Organization (ICAO) recently introduced language proficiency requirements for all flight personnel in all ICAO member states. Using an effective and economical experimental paradigm, the research described here teases apart the complex combination of factors (e.g. speech rate, controller message length, English language proficiency, cognitive workload) believed to contribute to miscommunications between controllers and pilots. Misunderstandings in ATC Communication offers an in-depth report of a seminal study in aviation communication, which until now has only been available in the form of an unpublished dissertation. In addition, it offers a recent extension of that work, the authors' reflections on the research process, and a thorough review of the aviation communication literature. Graduate students and researchers who wish to address real-world problems will appreciate the simple elegance of the experimental paradigm that has been used to address a wide range of theoretical and applied interdisciplinary research questions. The book will appeal to scholars in the fields of human factors, linguistics, cognitive psychology, applied linguistics and second-language education and assessment. It is also of direct relevance to government and industry decision-makers and operators as they strive to implement the ICAO requirements, and to improve aviation safety.

This book is devoted to studies of unsteady heat and mass exchange processes taking into account thermochemical destruction of thermal protective materials, research of transpiration cooling systems, thermal protection of composite materials exposed to low-energy disturbances, as well as the numerical solution of heat and mass transfer of the exchange. It proposes several mathematical models of passive and active thermal protection systems with regard to factors such as surface ablation, surface roughness, phase transition of a liquid in porous materials, rotation of the body around its longitudinal axis, and exposure to low-energy disturbances. The author studies the possibilities to control thermochemical destruction and heat mass exchange processes in transpiration cooling systems exposed to low-energy disturbances. The numerical analysis of the heat and mass exchange process in carbon plastics under repeated impulse action is also presented. The numerical solutions of problems are compared with the known experimental data. The book is intended for specialists in the field of thermal protection and heat mass exchange, as well as graduate and undergraduates in physics and mathematics.

Aeromedical psychology is that branch of psychology pertaining to the assessment, selection and evaluation of aviation personnel. This book, Aeromedical Psychology, is designed to provide the means for a variety of clinicians to carry out sound assessment and selection procedures, perform informed evaluations and make subsequent recommendations regarding flight status and treatment strategies geared to the aviation environment. To facilitate a dynamic understanding of the field, the book emphasizes an integration of applications and theory, case examples and research. The book is divided into three parts. The first presents assessment and selection procedures for aviation personnel (i.e. air traffic controllers, flight officers and pilots) and astronauts and the many ways in which both psychologists and psychiatrists are involved in these roles. In the second part, the waiver standards put forth by both the FAA and the various branches of the military are presented, as well as the waiver decision process. Clinical issues unique to aviation - notably fear of flying, motivation to fly and airsickness - are addressed, as well as possible courses of intervention, treatment and disposition. In the final part, more specialized issues pertaining to aeromedical psychology are dealt with, namely the psychopharmacological research and regulations applicable to recreational pilots and aviation personnel, managing the aftermath of aviation mishaps and the psychologist's role in accident investigations.
