This open access book presents the findings of Collaborative Research Center Transregio 40 (TRR40), initiated in July 2008 and funded by the German Research Foundation (DFG). Gathering innovative design concepts for thrust chambers and nozzles, as well as cutting-edge methods of aft-body flow control and propulsion-component cooling, it brings together fundamental research undertaken at universities, testing carried out at the German Aerospace Center (DLR) and industrial developments from the ArianeGroup. With a particular focus on heat transfer analyses and novel cooling concepts for thermally highly loaded structures, the book highlights the aft-body flow of the space transportation system and its interaction with the nozzle flow, which are especially critical during the early phase of atmospheric ascent. Moreover, it describes virtual demonstrators for combustion chambers and nozzles, and discusses their industrial applicability. As such, it is a timely resource for researchers, graduate students and practitioners.

Have you ever wondered how NASA designs, builds, and tests spacecrafts and hardware for space? How is it that wildly successful programs such as the Mars Exploration Rovers could produce a rover that lasted over ten times the expected prime mission duration? Or build a spacecraft designed to visit two orbiting destinations and last over 10 years when the fuel ran out? This book was written by NASA/JPL engineers with experience across multiple projects, including the Mars rovers, Mars helicopter, and Dawn ion propulsion spacecraft in addition to many more missions and technology demonstration programs. It provides useful and practical approaches to solving the most complex thermal-structural problems ever attempted for design spacecraft to survive the severe cold of deep space, as well as the unforgiving temperature swings on the surface of Mars. This is done without losing sight of the fundamental and classical theories of thermodynamics and structural mechanics that paved the way to more pragmatic and applied methods such finite element analysis and Monte Carlo ray tracing, for example. Features: Includes case studies from NASA’s Jet Propulsion Laboratory, which prides itself in robotic exploration of the solar system, as well as flyting the first cubeSAT to Mars. Enables spacecraft designer engineers to create a design that is structurally and thermally sound, and reliable, in the quickest time afforded. Examines innovative low-cost thermal and power systems. Explains how to design to survive rocket launch, the surfaces of Mars and Venus. Suitable for practicing professionals as well as upper-level students in the areas of aerospace, mechanical, thermal, electrical, and systems engineering, Thermal and Structural Electronic Packaging Analysis for Space and Extreme Environments provides cutting-edge information on how to design, and analyze, and test in the fast-paced and low-cost small satellite environment and learn techniques to reduce the design and test cycles without compromising reliability. It serves both as a reference and a training manual for designing satellites to withstand the structural and thermal challenges of extreme environments in outer space.

Corrugated-core structures were designed for ITPS applications with loads and boundary conditions similar to that of a Space Shuttle-like vehicle. Temperature, buckling, deflection and stress constraints were considered for the design process. An optimized mass ranging between 3.5--5 lb/ft2 was achieved by the design. This is considerably heavier when compared to conventional TPS designs. However, the ITPS can withstand substantially large mechanical loads when compared to the conventional TPS. Truss-core geometries used for ITPS design in this research were found to be unsuitable as they could not withstand large thermal gradients frequently encountered in ITPS applications. The corrugated-core design was used for further studying the influence of the various input parameters on the final design weight of the ITPS. It was observed that boundary conditions not only significantly influence the ITPS design but also have a major impact on the effect of various input parameters. It was found that even a small amount of heat loss from bottom face sheet leads to significant reduction in ITPS weight. Aluminum and Beryllium are the most suitable materials for bottom face sheet with Beryllium having considerable advantages in terms of heat capacity, stiffness and density. Although ceramic matrix composites have many superior properties when compared to metal alloys (Titanium alloys and Inconel), their low tensile strength presents difficulties in ITPS applications.
