The mechanics of similarity encompasses the analysis of dimensions, performed by various procedures, the gasdynamic similarity and the model technology. The analysis of dimensions delivers the dimensionless numbers by which specific physical challenges can be described with a reduced number of variables. Thereby the assessment of physical problems is facilitated. For fluid dynamics and all sorts of heat transfer the discipline of the mechanics of similarity was so important in the past, that the historical background is highlighted of all the persons who have contributed to the development of this discipline. The goal of the classical gasdynamic similarity was to find rules, which enables the aerodynamic engineer to perform transformations from existing flow fields to others, which meet geometrical and other specific flow field parameters. Most of these rules and findings do no longer play a role today, because a lot of potent experimental and theoretical/numerical methods are now available. This problem is addressed in the book. A recent investigation regarding the longitudinal aerodynamics of space vehicles has revealed, that there exist other astonishing similarities for hypersonic and supersonic flight Mach numbers. It seems, that obviously most of the longitudinal aerodynamics is independent from the geometrical configurations of the space vehicle considered, if a simple transformation is applied. A section of this book is devoted to these new findings.

This book concentrates on the subject of health monitoring technology of Liquid Rocket Engine (LRE), including its failure analysis, fault diagnosis and fault prediction. Since no similar issue has been published, the failure pattern and mechanism analysis of the LRE from the system stage are of particular interest to the readers. Furthermore, application cases used to validate the efficacy of the fault diagnosis and prediction methods of the LRE are different from the others. The readers can learn the system stage modeling, analyzing and testing methods of the LRE system as well as corresponding fault diagnosis and prediction methods. This book will benefit researchers and students who are pursuing aerospace technology, fault detection, diagnostics and corresponding applications.

The conference and the research presented here were partly supported by the CRC 880 on "Fundamentals of High Lift for Future Civil Aircraft," funded by the DFG (German Research Foundation). The papers offer timely insights into high-lift technologies for short take-off and landing aircraft, with a special focus on aeroacoustics, efficient high-lift, flight dynamics, and aircraft design.

This is the amazing story of Hanna Reitsch, one of the most celebrated women of the Third Reich. As a decorated test pilot for the Luftwaffe and a protege of Hitler, Reitsch was one of a handful of women who achieved personal success by breaking from the traditionally defined role of wife and mother in Nazi Germany. Reitsch's skills and accomplishments ultimately earned her an Iron Cross and celebrity status. A witness to the last days of the Third Reich, Reitsch visited Hitler's Berlin bunker where she received orders to deliver letters designed to rally the Luftwaffe. She left on this futile mission only minutes before Hitler's marriage to Eva Braun. This is the amazing story of Hanna Reitsch, a woman who excelled in an environment that for most was extremely repressive—Germany before and during World War II. She achieved personal success when she escaped the culturally defined role of wife and mother in Nazi Germany to live her passion for flying. Reitsch began her career flying gliders, setting both distance and endurance records in the 1930s. As the war approached she became a test pilot for new and dangerous aircraft for the Luftwaffe. The aircraft she flew included a large number of gliders and military aircraft, including Focke-Achgelis FW 61 Hubschrauber (the first practical helicopter), the jet-powered piloted version of the V-1 buzz bomb, and the rocket-powered Messerschmitt 163. Her achievements as a test pilot made her a celebrity in Nazi Germany and earned her an Iron Cross and the friendship of Hitler. As a friend of the Fuehrer, she became an eyewitness to the fall of the Third Reich. In the final days of World War II, she flew with her friend and lover, Luftwaffe General Robert Ritter von Greim—to join Hitler in his bunker. Minutes before Hitler was to marry Eva Braun, Reitsch and von Greim—on Hitler's orders—flew from Berlin to Rechlin in a desperate attempt to rally the Luftwaffe and save the Reich. After the war, Reitsch was interviewed as a potential witness for the Nuremberg War Crimes Trials. Her interviewer stated that [Hanna's] account of the flight into Berlin to report to Hitler and of her stay in the Fuehrer's bunker is probably as accurate a one as will be obtained of those last days. It has remained so for half a century. This book also recounts a vivid and remarkable encounter in a cemetery in Kitzbuehel, Austria, in June of 1945, between Leni Riefenstahl, the filmmaker, perhaps the only other woman to be so successful in the Third Reich, and Hanna Reitsch. During this chance encounter, Hanna shows the letters of Josef and Magda Goebbels to Riefenstahl and the reader shares their shocking contents. Hanna Reitsch found in the Nazi establishment opportunities and rewards for her achievements. Consorting with the devil paid well; yet, in the end, she was called on to pay back more than she had received. Her story shows how hard it is for a woman to excel in a repressive society, and how that success can lead to defeat and misery.

Rare views of the beginnings of a historic space programAfter the excitement of the first Moon landing, the U.S. space program took an ambitious new direction closer to home: NASA's Space Shuttle program promised frequent access to Earth orbit for medical and scientific breakthroughs; deploying, repairing and maintaining satellites; and assembling a space station. Picturing the Space Shuttle is the first photographic history of the program's early years as the world's first space plane debuted. Showcasing over 450 unpublished and lesser-known images, this book traces the growth of the Space Shuttle from 1965 to 1982, from initial concept through its first four space flights. The photographs offer windows into designing the first reusable space vehicle as well as the construction and testing of the prototype shuttle Enterprise. They also show the factory assembly and delivery of the Space Shuttle Columbia, preparations at the major NASA field centers, and astronaut selection and training. Finally, the book devotes a chapter to each of the first four orbital missions, STS-1 through STS-4, providing an abundance of seldom seen photos for each flight. Mostly selected from J. L. Pickering's personal archive, the world's largest private collection of U.S. human space flight images, the high-quality photographs in this book are paired with veteran journalist John Bisney's detailed descriptions and historical background information. The book also includes images of NASA and Shuttle contractor booklets, manuals, access badges, and press kits, as well as a foreword by Robert Crippen, the pilot of the first Space Shuttle flight. Picturing the Space Shuttle recreates the excitement of an era in which the possibilities of space exploration seemed limitless.

This book focuses on the nonlinear behaviour of thin-wall shells (single- and multilayered with delamination areas) under various uniform and non-uniform loadings.
The dependence of critical (buckling) load upon load variability is revealed to be highly non-monotonous, showing minima when load variability is close to the eigenmode variabilities of solution branching points of the respective nonlinear boundary problem.
A novel numerical approach is employed to analyze branching points and to build primary, secondary, and tertiary bifurcation paths of the nonlinear boundary problem for the case of uniform loading. The load levels of singular points belonging to the paths are considered to be critical load estimates for the case of non-uniform loadings.

Analytical solutions to the orbital motion of celestial objects have been nowadays mostly replaced by numerical solutions, but they are still irreplaceable whenever speed is to be preferred to accuracy, or to simplify a dynamical model. In this book, the most common orbital perturbations problems are discussed according to the Lie transforms method, which is the de facto standard in analytical orbital motion calculations.

This book is intended as a system engineer's compendium, explaining the dependencies and technical interactions between the onboard computer hardware, the onboard software and the spacecraft operations from ground. After a brief introduction on the subsequent development in all three fields over the spacecraft engineering phases each of the main topis is treated in depth in a separate part. The features of today's onboard computers are explained at hand of their historic evolution over the decades from the early days of spaceflight up to today. Latest system-on-chip processor architectures are treated as well as all onboard computer major components. After the onboard computer hardware the corresponding software is treated in a separate part. Both the software static architecture as well as the dynamic architecture are covered, and development technologies as well as software verification approaches are included. Following these two parts on the onboard architecture, the last part covers the concepts of spacecraft operations from ground. This includes the nominal operations concepts, the redundancy concept and the topic of failure detection, isolation and recovery. The baseline examples in the book are taken from the domain of satellites and deep space probes. The principles and many cited standards on spacecraft commanding, hardware and software however also apply to other space applications like launchers. The book is equally applicable for students as well for system engineers in space industry.
