This book gives insight into the mechanism of the immune system and the influence of the environment on earth. Further, the book explains the changes that occur in our immune system in the absence of gravity and their fundamental consequences. Several limiting factors for human health and performance in microgravity have been clearly identified as an unacceptable risk for long-term and interplanetary flights. Serious concerns arose whether spaceflight-associated immune system dysfunction ultimately precludes the expansion of human presence beyond Earth's orbit. The immune system has undergone many evolutionary steps to cope with a new and changing environment, but `space` has not been evolutionary experienced before. Through endocrine orchestration of cell functions, cell to cell communications and intracellular mechanisms the human body and his immune system have an enormous capacity to adapt and react to altered environmental conditions. Thus, the special sensitivity to altered gravity renders the immune system an ideal biological model system to understand if and how gravity on Earth is required for the normal function of cells and cellular networks. It is one of the most fundamental challenges to find out, if our organism and our cellular machinery are able to live and to adequately perform without the gravity field of Earth. The book is written for immunologists and researchers in human physiology under normal and stressfull conditions.

Aircraft Design explores fixed winged aircraft design at the conceptual phase of a project. Designing an aircraft is a complex multifaceted process embracing many technical challenges in a multidisciplinary environment. By definition, the topic requires intelligent use of aerodynamic knowledge to configure aircraft geometry suited specifically to the customer s demands. It involves estimating aircraft weight and drag and computing the available thrust from the engine. The methodology shown here includes formal sizing of the aircraft, engine matching, and substantiating performance to comply with the customer s demands and government regulatory standards. Associated topics include safety issues, environmental issues, material choice, structural layout, understanding flight deck, avionics, and systems (for both civilian and military aircraft). Cost estimation and manufacturing considerations are also discussed. The chapters are arranged to optimize understanding of industrial approaches to aircraft design methodology. Example exercises from the author s industrial experience dealing with a typical aircraft design are included."

This Brief discusses the current policy environment in which the United States space program operates and proposes an industry-government partnership as a long-term policy solution. Since the Reagan administration, American space policy has increasingly sought to involve private sector operators for space. The culmination of this trend has been the Obama administration's policy of private sector transportation of crew and cargo to the International Space Station on behalf of NASA. This book proposes that future administrations extend this policy to other areas of space, including energy, in orbit manufacturing, asteroid mining, and the exploration of the Moon and Mars. The book further demonstrates how these activities can stabilize the global political system and lead to a dramatic increase in global economic growth. Finally, the book addresses one of the most important and critical issues currently facing humanity-the need for a viable, baseload, and unlimited supply of totally clean energy. An extremely cogent analysis of the interrelationship between space activity and the terrestrial economy, this book showcases the political and economic potential of the medium of space and adds greatly to the existing literature in the field. This book will be of interest to students of political science and strategic studies as well as members of the military, government space agencies, and the international aerospace industry.

In order to facilitate the safe, efficient and cost effective exchange of passengers and cargo between ground and sky airports require the provision of adequate runways, aircraft manoeuvring areas, cargo sheds and passenger processing facilities. Airports are capital intensive facilities and planning errors which result in the over or under-provision of capacity are both costly and problematic to rectify and so understanding the optimal configuration of passenger terminals is paramount. Of course, the design of passenger terminal buildings is influenced not only by levels of demand, the commercial requirements of airlines and tenant companies, the availability of investment funds and political influence but also by the aircraft that will be using the facility both now and in the future. Indeed, the introduction of the first generation of passenger jets in the 1950s and higher-capacity wide-bodied aircraft in the late 1960s required not only the expansion of gate areas and passenger processing facilities but also the introduction of new technologies such as the travelator, the baggage reclaim carousel and the airbridge. The introduction of the A380 'Super Jumbo' into revenue passenger service in 2007 similarly demanded a reconfiguration of the airports it serves and practitioners need to be cognisant of the options for accommodating a new generation of large aircraft. While large aircraft generally require a lengthy turn around period between flights and the extensive provision of expensive fixed ground support infrastructure, low cost carriers pursue a business model based on very short turnarounds and minimal use of airport infrastructure assets such as airbridges. One of the main challenges facing airport operators is how to accommodate the diverse and dynamic requirements of different operators and these issues are addressed in this Volume. Traditionally, aircraft were made and manufactured by small companies within one country but as costs have increased and technology has become more sophisticated, a relatively small number of manufacturers, which are supported by international supply chains, have come to dominate the commercial aircraft market. Originally, all aviation jet fuels were derived from crude oil. However, concerns about future oil supply and energy security combined with the need to improve aviation's environmental performance and sustainability has driven the development of alternative fuel sources. However, the development and adoption of alternative aviation fuels is not straightforward and the Volume examines the opportunities and challenges of widespread biofuel adoption in terms of production capacity, emissions reductions, cost and commercial viability. The final essays in this Volume address business model innovation in the airline and airport sector and include considerations of the future evolution of low cost carriers, the potential for airline-airport alliances and the development of multi-airport multinational operating companies.

As both an enabler and accelerator of globalisation, aviation has had profound and sometime unintended and unanticipated social and economic impacts. Commercial airports are not only transport nodes that facilitate aerial movement they are also major centres of employment but often sites of political contestation surrounding their planning and development as economic growth imperatives conflict with environmental concerns. Noise is often cited as being one of the most socially contested aspects of airport operations for local communities, particularly when flights are operating during the night. This is a particular challenge for cargo operators whose business model is based on rapid overnight delivery and distribution. Specific factors including night noise curfews and the provision and co-location of freight forwarders are significant determinants of airport choice and this, in turn, leads to freight forwarding firms clustering at major freight facilities. As well as meeting the mobility needs of business travellers and cargo consignors, air travel also facilitates the mass movement of leisure passengers. The benefits, challenges and limits to growth of this market segment are explored together with the social, economic and environmental challenges tourism creates for receiving countries. The role of airlines in planning, developing and marketing tourist destinations is also examined in this Volume. Aviation-led tourist development is particularly pronounced in cities such as Singapore and Dubai where air service deregulation and airport-airline-destination marketing strategies have created not only major international transit hubs but also significant centres of international urban tourism. In addition to serving routes with high levels of passenger and cargo demand, aviation also performs a vital role for geographically remote and/or inaccessible regions that cannot be rapidly accessed by road, sea or rail. Owing to lower levels of demand, the need for small (and sometimes specially equipped aircraft) and the vagaries of the local weather and climate, these services are expensive to operate and may not be economically viable without subsidy. Experiences from the US and European Union examine some of the issues surrounding the operation of these services. The Volume concludes with consideration of aviation's environmental impacts and potential mitigation strategies such as the EU's Emissions Trading System.

The aviation industry is unique in two major ways: firstly, it has a long history of government involvement dating back to the early days of aviation; and secondly, its primary concern is the safety of its passengers and crew. These features highlight the importance of ethical decision-making at all levels of the industry. However, well-publicized problems such as the disappearance of Malaysia Airlines Flight 370 highlight the need for ethics to take a more prominent role in the field. Ethical Issues in Aviation focuses on both past and current topics in aviation, providing the reader with an overview of the major themes in aviation ethics that cover a broad range of subjects. Contributors include academics who do research in the field as well as professionals who provide first-hand accounts of the ethical situations that arise in the aviation industry. This second edition has been thoroughly revised throughout to bring it up to date, and features several new chapters that cover recent events and topics. This book enhances student learning by providing faculty, students, and those interested in aviation with discussion of the most pressing ethical issues that continue to impact the industry.

They are divided into 9 topics to match the corresponding sessions in CSNC2013, which broadly covered key topics in GNSS. Readers can learn about the BeiDou system and keep abreast of the latest advances in GNSS techniques and applications. SUN Jiadong is the Chief Designer of the Compass/BeiDou system, and the Academician of Chinese Academy of Sciences (CAS); JIAO Wenhai is a researcher at China Satellite Navigation Office; WU Haitao is a professor at Navigation Headquarters, CAS; SHI Chuang is a professor at Wuhan University.

Motion Coordination for VTOL Unmanned Aerial Vehicles develops new control design techniques for the distributed coordination of a team of autonomous unmanned aerial vehicles. In particular, it provides new control design approaches for the attitude synchronization of a formation of rigid body systems. In addition, by integrating new control design techniques with some concepts from nonlinear control theory and multi-agent systems, it presents a new theoretical framework for the formation control of a class of under-actuated aerial vehicles capable of vertical take-off and landing. Several practical problems related to the systems' inputs, states measurements, and restrictions on the interconnection topology between the aerial vehicles in the team are addressed. Worked examples with sufficient details and simulation results are provided to illustrate the applicability and effectiveness of the theoretical results discussed in the book. The material presented is primarily intended for researchers and industrial engineers from robotics, control engineering and aerospace communities. It also serves as a complementary reading for graduate students involved in research related to flying robotics, aerospace, control of under-actuated systems, and nonlinear control theory

The book presents a unique overview of activities in human spaceflight and exploration and a discussion of future development possibilities. It provides an introduction for the general public interested in space and would also be suitable for students at university. The book includes the basics of the space environment and the effects of space travel on the human body. It leads through the challenges of designing life support systems for spacecraft as wells as space suits to protect astronauts during extravehicular activities. Research being carried out by humans in Earth orbit is being brought into context to other forms of space exploration. Between the end of 2007 and May 2009 ESA, the European Space Agency, carried out an astronaut recruitment process. It was the first time that astronauts had been recruited newly to the corps since its creation in 1998 and the positions were open to citizens of all of the member states of ESA. Two of the contributors to this book participated in the selection process and hence contribute to a general discussion of how one carries out such a selection programme. The book concludes with one person's experience of flying aboard the space shuttle on a mission to map planet Earth, bringing together topics taken up in earlier parts of the book.

This thesis presents fundamental work that explains two mysteries concerning the trajectory of interplanetary spacecraft. For the first problem, the so-called Pioneer anomaly, a wholly new and innovative method was developed for computing all contributions to the acceleration due to onboard thermal sources. Through a careful analysis of all parts of the spacecraft Pioneer 10 and 11, the application of this methodology has yielded the observed anomalous acceleration. This marks a major achievement, given that this problem remained unsolved for more than a decade. For the second anomaly, the flyby anomaly, a tiny glitch in the velocity of spacecraft that perform gravity assisting maneuvers on Earth, no definitive answer is put forward; however a quite promising strategy for examining the problem is provided and a new mission is proposed. The proposal largely consists in using the Galileo Navigational Satellite System to track approaching spacecraft, and in considering a small test body that approaches Earth from a highly elliptic trajectory.

This book is about China’s ambitions in its most complex and internationally visible space endeavor, namely its human space exploration programme. It provides a comprehensive reflection on China´s strategic direction and objectives in space, including in particular those set forth in its human spaceflight programme and analyses the key domestic and external factors affecting the country’s presumed manned lunar ambitions. The objective of the book is to disentangle the opportunities and challenges China´s space ambitions are creating for other spacefaring nations and for Europe in particular. It therefore includes an in-depth analysis of possible European postures towards China in space exploration and seeks to stimulate a debate on future space strategies in the broader context of world politics.

This monograph presents the state of the art in aeroservoelastic (ASE) modeling and analysis and develops a systematic theoretical and computational framework for use by researchers and practicing engineers. It is the first book to focus on the mathematical modeling of structural dynamics, unsteady aerodynamics, and control systems to evolve a generic procedure to be applied for ASE synthesis. Existing robust, nonlinear, and adaptive control methodology is applied and extended to some interesting ASE problems, such as transonic flutter and buffet, post-stall buffet and maneuvers, and flapping flexible wing. The author derives a general aeroservoelastic plant via the finite-element structural dynamic model, unsteady aerodynamic models for various regimes in the frequency domain, and the associated state-space model by rational function approximations. For more advanced models, the full-potential, Euler, and Navier-Stokes methods for treating transonic and separated flows are also briefly addressed. Essential ASE controller design and analysis techniques are introduced to the reader, and an introduction to robust control-law design methods of LQG/LTR and H2/H synthesis is followed by a brief coverage of nonlinear control techniques of describing functions and Lyapunov functions. Practical and realistic aeroservoelastic application examples derived from actual experiments are included throughout. Aeroservoelasiticity fills an important gap in the aerospace engineering literature and will be a valuable guide for graduate students and advanced researchers in aerospace engineering, as well as professional engineers, technicians, and test pilots in the aircraft industry and laboratories.

Following the successful 1st CEAS (Council of European Aerospace Societies) Specialist Conference on Guidance, Navigation and Control (CEAS EuroGNC) held in Munich, Germany in 2011, Delft University of Technology happily accepted the invitation of organizing the 2nd CEAS EuroGNC in Delft, The Netherlands in 2013. The goal of the conference is to promote new advances in aerospace GNC theory and technologies for enhancing safety, survivability, efficiency, performance, autonomy and intelligence of aerospace systems using on-board sensing, computing and systems. A great push for new developments in GNC are the ever higher safety and sustainability requirements in aviation. Impressive progress was made in new research fields such as sensor and actuator fault detection and diagnosis, reconfigurable and fault tolerant flight control, online safe flight envelop prediction and protection, online global aerodynamic model identification, online global optimization and flight upset recovery. All of these challenges depend on new online solutions from on-board computing systems. Scientists and engineers in GNC have been developing model based, sensor based as well as knowledge based approaches aiming for highly robust, adaptive, nonlinear, intelligent and autonomous GNC systems. Although the papers presented at the conference and selected in this book could not possibly cover all of the present challenges in the GNC field, many of them have indeed been addressed and a wealth of new ideas, solutions and results were proposed and presented. For the 2nd CEAS Specialist Conference on Guidance, Navigation and Control the International Program Committee conducted a formal review process. Each paper was reviewed in compliance with good journal practice by at least two independent and anonymous reviewers. The papers published in this book were selected from the conference proceedings based on the results and recommendations from the reviewers.

Computational aeroacoustics (CAA) is a relatively new research area. CAA algorithms have developed rapidly and the methods have been applied in many areas of aeroacoustics. The objective of CAA is not simply to develop computational methods but also to use these methods to solve practical aeroacoustics problems and to perform numerical simulation of aeroacoustic phenomena. By analysing the simulation data, an investigator can determine noise generation mechanisms and sound propagation processes. This is both a textbook for graduate students and a reference for researchers in CAA and as such is self-contained. No prior knowledge of numerical methods for solving partial differential equations (PDEs) is needed, however, a general understanding of partial differential equations and basic numerical analysis is assumed. Exercises are included and are designed to be an integral part of the chapter content. In addition, sample computer programs are included to illustrate the implementation of the numerical algorithms.

Selecting the right aircraft for an airline operation is a vastly complex process, involving a multitude of skills and considerable knowledge of the business. Buying the Big Jets has been published since 2001 to provide expert guidance to all those involved in aircraft selection strategies. This third edition brings the picture fully up to date, representing the latest developments in aircraft products and best practice in airline fleet planning techniques. It features a new section that addresses the passenger experience and, for the first time, includes regional jet manufacturers who are now extending their product families into the 100-plus seating category. Overall, the third edition looks at a broader selection of analytical approaches than previously and considers how fleet planning for cost-leader airlines differs from that of network carriers. Buying the Big Jets is an industry-specific example of strategic planning and is therefore a vital text for students engaged in graduate or post-graduate studies either in aeronautics or business administration. The book is essential reading for airline planners with fleet planning responsibility, consultancy groups, analysts studying aircraft performance and economics, airline operational personnel, students of air transport, leasing companies, aircraft value appraisers, and all who manage commercial aircraft acquisition programmes and provide strategic advice to decision-makers. It is also a valuable tool for the banking community where insights into aircraft acquisition decisions are vital.

This book focuses on systems engineering, systems thinking, and how that thinking can be learned in practice. It describes a novel analytical framework based on activity theory for understanding how systems thinking evolves and how it can be improved to support multidisciplinary teamwork in the context of system development and systems engineering. This method, developed using data collected over four years from three different small space systems engineering organizations, can be applied in a wide variety of work activities in the context of engineering design and beyond in order to monitor and analyze multidisciplinary interactions in working teams over time. In addition, the book presents a practical strategy called WAVES (Work Activity for a Evolution of Systems engineering and thinking), which fosters the practical learning of systems thinking with the aim of improving process development in different industries. The book offers an excellent resource for researchers and practitioners interested in systems thinking and in solutions to support its evolution. Beyond its contribution to a better understanding of systems engineering, systems thinking and how it can be learned in real-world contexts, it also introduce a suitable analysis framework that helps to bridge the gap between the latest social science research and engineering research.

Intended as a textbook for courses in computational fluid dynamics at the senior undergraduate or graduate level, this book is a follow-up to the book Fundamentals of Computational Fluid Dynamics by the same authors, which was published in the series Scientific Computation in 2001. Whereas the earlier book concentrated on the analysis of numerical methods applied to model equations, this new book concentrates on algorithms for the numerical solution of the Euler and Navier-Stokes equations. It focuses on some classical algorithms as well as the underlying ideas based on the latest methods. A key feature of the book is the inclusion of programming exercises at the end of each chapter based on the numerical solution of the quasi-one-dimensional Euler equations and the shock-tube problem. These exercises can be included in the context of a typical course and sample solutions are provided in each chapter, so readers can confirm that they have coded the algorithms correctly.
