In recent years, an unprecedented interest in novel and revolutionary space missions has risen out of the advanced NASA and ESA programs. Astrophysicists, astronomers, space systems engineers, mathematicians and scientists have been cooperating to implement novel and ground-breaking space missions. Recent progress in mathematical dynamics has enabled development of specialised spacecraft orbits and propulsion systems. Recently, the concept of flying spacecraft in formation has gained a lot of interest within the community. These progresses constitute the background to a significant renaissance of research dealing with astrodynamics and its applications. Modern Astrodynamics is designed as a stepping stone for the exposition of modern astrodynamics to students, researchers, engineers and scientists. This volume will present the main constituents of the astrodynamical science in an elaborate, comprehensive and rigorous manner. Although the volume will contain a few distinct chapters, it will render a coherent portrayal of astrodynamics. Encompasses the main constituents of the astrodynamical sciences in an elaborate, comprehensive and rigorous manner Presents recent astrodynamical advances and describes the challenges ahead The first volume of a series designed to give scientists and engineers worldwide an opportunity to publish their works in this multi-disciplinary field

Space agencies are now realizing that much of what has previously been achieved using hugely complex and costly single platform projects—large unmanned and manned satellites (including the present International Space Station)—can be replaced by a number of smaller satellites networked together. The key challenge of this approach, namely ensuring the proper formation flying of multiple craft, is the topic of this second volume in Elsevier’s Astrodynamics Series, Spacecraft Formation Flying: Dynamics, control and navigation. In this unique text, authors Alfriend et al. provide a coherent discussion of spacecraft relative motion, both in the unperturbed and perturbed settings, explain the main control approaches for regulating relative satellite dynamics, using both impulsive and continuous maneuvers, and present the main constituents required for relative navigation. The early chapters provide a foundation upon which later discussions are built, making this a complete, standalone offering. Intended for graduate students, professors and academic researchers in the fields of aerospace and mechanical engineering, mathematics, astronomy and astrophysics, Spacecraft Formation Flying is a technical yet accessible, forward-thinking guide to this critical area of astrodynamics. The first book dedicated to spacecraft formation flying, written by leading researchers and professors in the field Develops the theory from an astrodynamical viewpoint, emphasizing modeling, control and navigation of formation flying satellites on Earth orbits Examples used to illustrate the main developments, with a sample simulation of a formation flying mission included to illustrate high fidelity modeling, control and relative navigation

This introductory text covers all the key concepts, relationships, and ideas behind spaceflight and is the perfect companion for students pursuing courses on or related to astronautics. As a crew member of the STS-55 Space Shuttle mission and a full professor of astronautics at the Technical University of Munich, Ulrich Walter is an acknowledged expert in the field. This book is based on his extensive teaching and work with students, and the text is backed up by numerous examples drawn from his own experience. With its end-of-chapter examples and problems, this work is suitable for graduate level or even undergraduate courses in spaceflight, as well as for professionals working in the space industry. This third edition includes substantial revisions of several sections to extend their coverage. These include both theoretical extensions such as the study of relative motion in near-circular orbits, and more practical matters such as additional details about jet-engine and general rocket performance. New sections address regularized equations of orbital motion and their algebraic solutions and also state vector propagation; two new chapters are devoted to orbit geometry and orbit determination and to thermal radiation physics and modelling.

Seit dem Erscheinen der ersten Auflage vor fast 30 Jahren ist das Handbuch des kathodischen Korrosionsschutzes zu einem Klassiker geworden. Der Erfolgstitel liegt nun in der vierten Auflage vor. Kathodischer Korrosionsschutzes hat in den vergangenen Jahren nichts an seiner Bedeutung verloren - er ist auch heute noch eines der wichtigsten Verfahren des Korrosionschutzes überhaupt. Auf einigen Gebieten wie dem Schutz von Stahlbeton ist seine Bedeutung sogar noch gewachsen. Gut zehn Jahre nach dem Erscheinen der dritten Auflage musste in vielen Bereichen eine Neubearbeitung durchgeführt werden. Das gilt - wie bereits bei früheren Auflagen - für die Messtechnik zum Nachweis der ausreichenden Schutzwirkung mit der praktischen Anwendung bei Rohrleitungen und Fragen der Beeinflussung durch Gleichströme sowie die Wirkung von Wechselspannungen. Im Bereich der Korrosion bilden die verschiedenen Arten der Risskorrosion und die Wechselstromkorrosion Schwerpunkte der Überarbeitung. Auf dem Gebiet der Messtechnik und der Umhüllungsschäden wurden neuartige Beschriebungen der elektrischen Eigenschaften von Beschichtungsfehlstellen entwickelt. Die vierte Auflage erscheint in einer Zeit der verstärkten internationalen Zusammenarbeit - insbesondere bei der Normung - und eines zunehmenden Sicherbeitsbedarfs. Deshalb dient das Handbuch auch der Wissenserhaltung mit allen zugehörigen Grundlagenwissenschaften und gegebenenfalls auch zur Basis von Qualifikationsnachweisen. Wieder haben zahlreiche Fachleute aus der Industrie ihr Fachwissen zum weltweit einzigartigen Standardwerk über alle Anwendungsbereiche der elektrochemischen Korrosionsschutzverfahren beigetragen. Dabei wurde Wert auf lückenlose Querverweise zwischen den einzelnen Kapiteln und einheitliche bzw. normgerechte Terminologie gelegt. Das Handbuch ist nicht nur unentbehrlich für Unternehmen für kathodischen Schutz, sondern ist für alle Personen, die sich mit Korrosion und Korrosionsschutz beschäftigen, zum Nachschlagen und zur Weiterbildung geeignet.
