This book focuses on the damage, fracture and fatigue of ceramic-matrix composites. It investigates tensile damage and fracture, fatigue hysteresis, and the properties of interfaces subjected to cyclic fatigue loading. Further, it predicts fatigue life at room and elevated temperatures using newly developed damage models and methods, and it analyzes and compares damage, fracture and fatigue behavior of different fiber performs: unidirectional, cross-ply, 2D and 2.5D woven. The developed models and methods can be used to predict the damage and lifetime of ceramic-matrix composites during applications on hot section components.Ceramic-matrix composites (CMCs) are high-temperature structural materials with the significant advantages of high specific strength, high specific modulus, high temperature resistance and good thermal stability, which play a crucial role in the development of high thrust weight ratio aero engines. The critical nature of the application of these advanced materials makes comprehensive characterization a necessity, and as such this book provides designers with essential information pertaining not only to the strength of the materials, but also to their fatigue and damage characteristics.

This book shares a range of new and diverse insights on On-Orbit Servicing (OOS), and examines its implications especially from political, legal, economic, and security perspectives. OSS has been evolving rapidly and presents both challenges and opportunities, such as in-space repairs, refuelling, refurbishment of spacecraft and servicing satellites, which could play a critical role in extending satellite lifecycles, while also representing a valuable next step in debris mitigation. At the same time, many legal questions have arisen in connection with OOS: the need to prevent hostile actions under the pretext of OSS; the distinction between governmental and non-governmental OOS operators; the status of re-worked and recycled space objects; the issue of control in terms of operations performed in orbit, i.e., in the international sphere; the status of objects manufactured in orbit and applicable law, including liability and registration; and the impacts on insurance law and risk management. Finally, the book examines the implications of OOS for emerging space actors in the Global South, and recommends a paradigm shift to help developing countries fully recognise the necessity and urgency of being involved in discussions on OSS, as opposed to leaving it up to the developed space actors. This book will be of great interest to practitioners, academics, and students working in the space sector and related fields.

This volume is about ultra high-speed cameras, which enable us to see what we normally do not see. These are objects that are moving very fast, or that we just ignore. Ultra high-speed cameras invite us to a wonderland of microseconds. There Alice (the reader) meets a ultra high-speed rabbit (this volume) and travels together through this wonderland from the year 1887 to 2017. They go to the horse riding ground and see how a horse gallops. The rabbit takes her to a showroom where various cameras and illumination devices are presented. Then, he sends Alice into semiconductor labyrinths, wind tunnels, mechanical processing factories, and dangerous explosive fields. Sometimes Alice is large, and at other times she is very small. She sits even inside a car engine. She falls down together with a droplet. She enters a microbubble, is thrown out with a jet stream, and finds herself in a human body. Waking up from her dream, she sees children playing a game: "I see what you do not see, and this is....". Alice thinks: "The ultra high-speed rabbit showed me many things which I had never seen. Now I will go again to this wonderland, and try to find something new.

Science writer Willy Ley inspired Americans of all ages to imagine a future of interplanetary travel long before space shuttles existed. This is the first biography of an important public figure who predicted and boosted the rise of the Space Age, yet has been overlooked in the history of science. Born in Germany, Ley became involved in amateur rocketry until the field was taken over by the Nazi regime. He fled to America, where he forged a path as a weapons expert and journalist during World War II, and as a rocket researcher after the war. As America's foremost authority on rockets and space travel, he wrote many books and articles for science fiction magazines. He was a consultant for television's Tom Corbett, Space Cadet and the Disney program Man in Space, thrilling public audiences with a romanticized view of what spaceflight would be like. Yet as astronauts took center stage and scientific intellectuals such as Wernher von Braun became influential during the space race, Ley lost his celebrity status. He was ignored by younger historians who saw his style of popular writing as old-fashioned. This book returns Willy Ley to his rightful place as the energizer of an era-a time when scientists and science popularizers shared prestige and mixed ranks to make outlandish dreams come true.

The research has accumulated a large amount of experimental data, which has proven the significant effectiveness of LSP on the improvement of the fatigue performance of metal parts, and related findings have been successfully applied in aerospace field. This book could be used by the researchers who work in the field of LSP, mechanical strength, machine manufacturing and surface engineering, as well as who major in laser shock wave and materials science.

The book provides a structural analysis of the European space effort from an institute change perspective. It analyzes the EU-ESA inter-institutional relationship, gives an overview of the development of space policy in Europe, and advances the debate about the impact of the European integration process on existing institutional actors. While European Space collaboration was initially developed outside the competences of the European Union (EU) with space programmes being carried out almost exclusively under the framework of European Space Agency (ESA) and national agencies, the EU has gained "shared competences" (Art. 2, TFEU) in space policy following the adoption of the Lisbon Treaty. Currently the EU and ESA work together under a Framework Agreement. In 2016, the EU Commission has published a Communication entitled "European Space Policy" (ESP). Even though ESA's Member States have agreed to keep ESA as an intergovernmental organisation during the ESA Ministerial Council of 2014, the discussion about ESA becoming part of the EU framework continues. The EU's ambitions for leadership in European space policy raise question concerning the future of ESA. The study of institutions lies at the heart of political sciences. Strikingly the theoretic framework qualifying institutional change and making it comparable leaves room for more concrete and testable dimensions of institutional change.
