Race to the Moon is a suspenseful thriller about the 30-year clash between the United States and the Soviet Union to be the first to put a man on the moon. This true account is heavy with intrigue, espionage, and controversy. Beginning with a 1961 pledge by President John F. Kennedy to plant the Stars and Stripes on the lunar surface by the end of the decade, the story flashes back to the first days of World War II. At that time, England was tipped off by a high Nazi official that the Third Reich was developing revolutionary long-range rockets. This same source clandestinely provided documents that shocked British scientists: The Germans were 25 years ahead of England and the United States in rocket development! And then, in September 1944, 60-foot-long V-2 rockets, for which there was no defense, began raining down on London, causing enormous destruction and loss of life. Even while the fighting was still raging in Germany in the spring of 1945, a handful of young U.S. Army officers scored a colossal coup: They connived to steal 100 of the huge V-2s that had been found in an underground factory. They were dismantled and slipped by train out of Germany, destination White Sands, New Mexico. Then began a no-holds-barred search for German rocket scientists in the chaos of a defeated Third Reich, with the Americans and British on one side and the Russians on the other. Within weeks of the close of the war, Wernher von Braun and 126 of his rocket team members were corraled, shipped to the United States, and began working secretly on missile development. At the same time, the Soviets literally kidnapped other German rocket scientists and sent them to Russia to continue their space work. In the years ahead, Wernher von Braun and his German rocket team, nearly all of whom became naturalized citizens of the United States, collaborated with American scientists to overcome enormous space achievements by the Soviets--and bungling by Washington politicians--to send Neil Armstrong scampering about on the moon in 1969.

Special emphasis is given to collaborative research projects conducted by German scientists and engineers from universities, research-establishments and industries. By addressing a number of cutting-edge applications, together with the relevant physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field. Though the book's primary emphasis is on the aerospace context, it also addresses further important applications, e.g. in ground transportation and energy.
Aircraft are becoming increasingly reliant on computing and networking technologies, with the advent of the Internet of Things, but this makes them vulnerable to cyber-attacks. This multidisciplinary book is at the cross section of aircraft systems, cybersecurity, and defence technologies. It covers the very latest in defending military and commercial aircraft against cyber-attacks. The interdisciplinary nature of aviation cybersecurity and its wide-ranging impact in various arenas require contributions of expertise from multiple disciplines to collaborate in identifying the most feasible ways forward. This book provides an understanding of the key technical, social and legal issues in aviation cybersecurity, explains the range of technical challenges involved, and proposes innovative solutions. Aviation Cybersecurity: Foundations, principles, and applications is a valuable resource for aviation and cybersecurity researchers and professionals in academia, industry, and military organisations.
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.
We are the first species with the ability to leave planet Earth and expand the horizons of existence into the infinite realm of the universe. Humanity has been working, learning and building toward this accomplishment throughout history. Those who live and work in space will be no different from their predecessors who left ancient homelands to venture into the unknown wilderness. But to travel and work in space, one must not only know the physical characteristics of the space environment, but also something about the human beings involved. Living in Space explains: -Technology necessary for staying happy, healthy and alive in space. - Effects of acceleration on the human body - The long term affects of living in zero-g conditions - The most harmful forms of ionizing radiation for humans - Nutrition and Sanitation - Basic problems of working in space. The people who go into space to live and work are setting the foundation for humanity s future."
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
Performance calculations can be classified into three main types: lift, thrust and slope. Firstly, since the lift profile is known and unmodifiable from the time an aircraft is designed, the mass at a given speed or the speed at a given mass must be determined. Then, once the thrust of the engines and the mass are known, the slope must be calculated. Finally, once the slope is known (for example, level flight) as well as the mass, it is necessary to deduce the thrust; this is the position of the throttle control lever that ensures balance. The corresponding consumption must then be defined. Performance specifications for customer aircraft, such as manoeuvrability, fuel consumption, maintenance, safety and testability, have become ever more demanding with each generation of equipment. Major technical advances have been required: wing profiles, engines, materials to reduce mass, etc. This book presents a theoretical approach to flight mechanics that makes it possible to grasp the subject and links it with the empirical approach of manufacturers.
The book presents the best articles presented by researchers, academicians and industrial experts in the International Conference on "Innovative Design and Development Practices in Aerospace and Automotive Engineering (I-DAD 2016)". The book discusses new concept designs, analysis and manufacturing technologies, where more swing is for improved performance through specific and/or multifunctional linguistic design aspects to downsize the system, improve weight to strength ratio, fuel efficiency, better operational capability at room and elevated temperatures, reduced wear and tear, NVH aspects while balancing the challenges of beyond Euro IV/Barat Stage IV emission norms, Greenhouse effects and recyclable materials. The innovative methods discussed in the book will serve as a reference material for educational and research organizations, as well as industry, to take up challenging projects of mutual interest.

An additional coursework study on flight control design for an unmanned air vehicle (UAV).
The book sheds new lights on the evolution of Russian space activities with a focus on their strategy of international cooperation. This analysis is carried out in relation to the evolution of the domestic and international dynamics that have been impacting the country's direction in space, with the ultimate goal of providing an assessment on their impact for current and foreseeable Europe-Russia space relations. Russia has traditionally been one of the two main strategic partners for Europe in its space endeavor. Hitherto, long-standing cooperation has been nurtured between the two actors in various areas, from scientific research to space transportation and human spaceflight. In recent years, however, a number of endogenous and exogenous developments has triggered significant changes in Russia's space posture. These changes are evident in the adjustment of Russia's space policies and programmatic goals, in the restructuring of the domestic space industry as well as in the attitude towards international space partnerships.
