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 book investigates Venus and Mercury prospective energy and material resources. It is a collection of topics related to exploration and utilization of these bodies. It presents past and future technologies and solutions to old problems that could become reality in our life time. The book therefore is a great source of condensed information for specialists interested in current and impending Venus and Mercury related activities and a good starting point for space researchers, inventors, technologists and potential investors. Written for researchers, engineers, and businessmen interested in Venus and Mercury exploration and exploitation.

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.

For readers of "The Astronaut Wives Club, The Mercury 13 "reveals the little-known true story of the remarkable women who trained for NASA space flight.
In 1961, just as NASA launched its first man into space, a group of women underwent secret testing in the hopes of becoming America's first female astronauts. They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys' club at NASA and on Capitol Hill. The USSR sent its first woman into space in 1963; the United States did not follow suit for another twenty years.
For the first time, Martha Ackmann tells the story of the dramatic events surrounding these thirteen remarkable women, all crackerjack pilots and patriots who sometimes sacrificed jobs and marriages for a chance to participate in America's space race against the Soviet Union. In addition to talking extensively to these women, Ackmann interviewed Chuck Yeager, John Glenn, Scott Carpenter, and others at NASA and in the White House with firsthand knowledge of the program, and includes here never-before-seen photographs of the Mercury 13 passing their Lovelace tests.
Despite the crushing disappointment of watching their dreams being derailed, the Mercury 13 went on to extraordinary achievement in their lives: Jerrie Cobb, who began flying when she was so small she had to sit on pillows to see out of the cockpit, dedicated her life to flying solo missions to the Amazon rain forest; Wally Funk, who talked her way into the Lovelace trials, went on to become one of the first female FAA investigators; Janey Hart, mother of eight and, at age forty, the oldest astronaut candidate, had the political savvy to steer the women through congressional hearings and later helped found the National Organization for Women.
A provocative tribute to these extraordinary women, The Mercury 13 is an unforgettable story of determination, resilience, and inextinguishable hope.

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.

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.

This text provides an introduction to structural dynamics and aeroelasticity, with an emphasis on conventional aircraft. The primary areas considered are structural dynamics, static aeroelasticity and dynamic aeroelasticity. The structural dynamics material emphasizes vibration, the modal representation and dynamic response. Aeroelastic phenomena discussed include divergence, aileron reversal, airload redistribution, unsteady aerodynamics, flutter and elastic tailoring. More than one hundred illustrations and tables help clarify the text and more than fifty problems enhance student learning. This text meets the need for an up-to-date treatment of structural dynamics and aeroelasticity for advanced undergraduate or beginning graduate aerospace engineering students.

The articles in this volume present the state-of-the-art in noise prediction, modeling and measurement. The articles are partially based on class notes provided during the course `Noise sources in turbulent shear flows', given at CISM on April 2011. The first part contains general concepts of aero acoustics, including vortex sound theory and acoustic analogies, in the second part particular emphasis is put into arguments of interest for engineers and relevant for aircraft design: jet noise, airfoil broadband noise, boundary layer noise (including interior noise and its control) and the concept of noise sources, their theoretical modeling and identification in turbulent lows. All these arguments are treated extensively with the inclusion of many practical examples and references to engineering applications.

As we stand poised on the verge of a new era of spaceflight, we must rethink every element, including the human dimension. This book explores some of the contributions of psychology to yesterday's great space race, today's orbiter and International Space Station missions, and tomorrow's journeys beyond Earth's orbit. Early missions into space were typically brief, and crews were small, often drawn from a single nation. As international cooperation in space exploration has increased over the decades, the challenges of communicating across cultural boundaries and dealing with interpersonal conflicts have become all the more important, requiring different coping skills and sensibilities than "the right stuff" expected of early astronauts. As astronauts travel to asteroids or establish a permanent colony on the Moon, with the eventual goal of reaching Mars, the duration of expeditions will increase markedly, as will the psychosocial stresses. Away from their home planet for extended times, future spacefarers will need to be increasingly self-sufficient, while simultaneously dealing with the complexities of heterogeneous, multicultural crews. "On Orbit and Beyond: Psychological Perspectives on Human Spaceflight," the second, considerably expanded edition of "Psychology of Space Exploration: Contemporary Research in Historical Perspective," provides an analysis of these and other challenges facing future space explorers while at the same time presenting new empirical research on topics ranging from simulation studies of commercial spaceflights to the psychological benefits of viewing Earth from space. This second edition includes an all new section exploring the challenges astronauts will encounter as they travel to asteroids, Mars, Saturn, and the stars, requiring an unprecedented level of autonomy. Updated essays discuss the increasingly important role of China in human spaceflight. In addition to examining contemporary psychological research, several of the essays also explicitly address the history of the psychology of space exploration. Leading contributors to the field place the latest theories and empirical findings in historical context by exploring changes in space missions over the past half century, as well as reviewing developments in the psychological sciences during the same period. The essays are innovative in their approaches and conclusions, providing novel insights for behavioral researchers and historians alike.

In the early twentieth century, the new technology of flight changed warfare irrevocably, not only on the battlefield, but also on the home front. As prophesied before 1914, Britain in the First World War was effectively no longer an island, with its cities attacked by Zeppelin airships and Gotha bombers in one of the first strategic bombing campaigns. Drawing on prewar ideas about the fragility of modern industrial civilization, some writers now began to argue that the main strategic risk to Britain was not invasion or blockade, but the possibility of a sudden and intense aerial bombardment of London and other cities, which would cause tremendous destruction and massive casualties. The nation would be shattered in a matter of days or weeks, before it could fully mobilize for war. Defeat, decline, and perhaps even extinction, would follow. This theory of the knock-out blow from the air solidified into a consensus during the 1920s and by the 1930s had largely become an orthodoxy, accepted by pacifists and militarists alike. But the devastation feared in 1938 during the Munich Crisis, when gas masks were distributed and hundreds of thousands fled London, was far in excess of the damage wrought by the Luftwaffe during the Blitz in 1940 and 1941, as terrible as that was. The knock-out blow, then, was a myth. But it was a myth with consequences. For the first time, The Next War in the Air reconstructs the concept of the knock-out blow as it was articulated in the public sphere, the reasons why it came to be so widely accepted by both experts and non-experts, and the way it shaped the responses of the British public to some of the great issues facing them in the 1930s, from pacifism to fascism. Drawing on both archival documents and fictional and non-fictional publications from the period between 1908, when aviation was first perceived as a threat to British security, and 1941, when the Blitz ended, and it became clear that no knock-out blow was coming, The Next War in the Air provides a fascinating insight into the origins and evolution of this important cultural and intellectual phenomenon, Britain's fear of the bomber.

This book provides an overview of microgravity-induced changes in human metabolism, muscle, bone and the cardio-vascular system, and discusses in detail the nutrient uptake required during spaceflight to counteract these adaptive mechanisms and ensure an improved physical constitution upon returning to Earth.

This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).

Putting the "I" in IHY This book is about international cooperation. It demonstrates how the power of scienti?c imagination and investigation can bring together people form all continents in almost all countries around the globe. In presenting this impressive result, we can understand, how much unifying force the quest for understanding our universe and using outer space for that purpose have. Astronomy is far away from being a "political" area of science. But is has enormous political effects - and all of these effects are positive. This book about the international aspects and achievements of the "International Heliophysical Year (IHY) 2007" can be regarded as a compendium of the fertile impacts of conducting research in this ?eld. The main focus, as the title implicates, is the international cooperation, which has emerged from this grassroots initiative. North and South, industrialized and developing countries have been coordinating their efforts and have been learning from each other in a mutual partnership under a joint understanding of sharing the scienti?c bene?ts. Through this, trans-border networks have been created and scienti?c as well as cultural exchange took place.
