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.

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.

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.

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.

This book discusses the recent advanced technologies in Intelligent Transportation Systems (ITS), with a view on how Unmanned Aerial Vehicles (UAVs) cooperate with future vehicles. ITS technologies aim to achieve traffic efficiency and advance transportation safety and mobility. Known as aircrafts without onboard human operators, UAVs are used across the world for civilian, commercial, as well as military applications. Common deployment include policing and surveillance, product deliveries, aerial photography, agriculture, and drone racing. As the air-ground cooperation enables more diverse usage, this book addresses the holistic aspects of the recent advanced technologies in ITS, including Information and Communication Technologies (ICT), cyber security, and service management from principle and engineering practice aspects. This is achieved by providing in-depth study on several major topics in the fields of telecommunications, transport services, cyber security, and so on. The book will serve as a useful text for transportation, energy, and ICT societies from both academia and industrial sectors. Its broad scope of introductory knowledge, technical reviews, discussions, and technology advances will also benefit potential authors.

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.

Following current trends toward development of novel materials and structures, this volume explores the concept of high-performance metamaterials and metastructures with extremal mechanical properties, inspired by tensegrity systems. The idea of extremal materials is applied here to cellular tensegrity lattices of various scales. Tensegrity systems have numerous advantages: they are lightweight, have a high stiffness-to-mass ratio, are prone to structural control, can be applied in smart and adaptive systems, and exhibit unusual mechanical properties. This study is focused on tensegrity lattices, whose inner architecture resembles that of cellular metamaterials, but which are aimed at civil engineering applications in non-material scales. It proposes a methodology for investigation of extremal mechanical properties of such systems, based on discrete and continuum approaches, including the discussion on scale effects. It proves that, similarly to tensegrity-based metamaterials, tensegrity metastructures are able to exhibit extremal mechanical behaviour. This book is directed to researchers and scientists working on metamaterials and tensegrity systems, developing energy-absorption solutions for building and transport industry. The findings described in this monograph can also be useful in other fields of applied sciences, such as civil engineering, robotics and material science.

Mission Geometry: Orbit and Constellation Design and Management (OCDM) is the most complete treatment available for many elements of space mission design and astronautics.

OCDM discusses both the similarities and differences between orbit and altitude systems in terms of hardware, algorithms, design, and processing requirements. With the demand for reduced cost and the introduction of extensive on-board computing, what were once entirely separate disciplines have begun to merge. This volume will speed that process.

In all areas, OCDM is meant to be practical, with recommendations, insights, formulas, and numerical recipes based on 40 years of spaceflight experience from organizations worldwide. It is meant to be both a text and reference work that can be used by those entering the field and by senior engineers engaged in the design, analysis, construction, or on-orbit operations of orbit and attitude systems and components.

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 presents the fundamental methods of modeling, analysis and synthesis of transport processes which allow: - to optimize the work of transport organizations according to different criteria of their functioning; - to evaluate the quality of decisions made in conditions of high entropy and uncertainty of technological processes when applying new technologies and systems; -to reduce the negative impact of the human factor on the safety of ongoing transport processes by increasing the motivational component of the training processes for the operator of active transport systems. The structural diagrams presented in this book make it possible to visualize the processes of training, self-training of operators and the mechanisms of the formation of volitional motivational efforts under various external influences of the environment and the teacher–instructor. The obtained functional dependencies serve as an assessment for determining and forming the dynamics of motivation and making a decision about the readiness for safe work of the operator of active transport systems and the decision-maker in the new conditions of the technological process.

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.

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.

Stanley Hooker joined the Bristol Aeroplane Company in 1949 and tugged a rather reluctant company into the jet age, determined to give real competition to Rolls-Royce. So successful was he that in 1966 Rolls-Royce decided the best thing to do was to spend 63.6 million pounds and buy its rival. By this time there was scarcely a single modern British aero-engine for which Hooker had not been responsible.

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."

Striking a healthy balance between theory and practice, and featuring in-depth studies and extensive experimental results, the book introduces beginners to the fundamentals, while preparing experienced researchers to pursue advanced investigations and applications in GNSS-R.

With major structural changes will need to be thoroughly reexamined. This book discusses decision making for problems where a particular decision affects the options available at the next decision time. The deregulation of the electric utility industry will shift the emphasis from a cost-based to a price-based approach; the resulting occuring in the electric power industry, many long-standing ways of operation increase in uncertainty requires that a stochastic approach be adopted for optimal decision-making. This monograph covers a wide range of topics including dynamic programming, ordinal optimization, price modelling and forecasting, future market decisions, reserve market decisions and decisions in a congested market place.

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.
