Book Description
The importance of surface radiation characteristics in controlling the internal temperature of space vehicles has been comprehensively reviewed by other investigatorsl. It is imperative that extraterrestrial vehicles now in design be provided a surface with a ratio of solar absorptance (alpha) to long wavelength emittance (epsilon) equal to about 0. 15 to 0. 18. Ideally, a surface should possess an alpha of 0.10 and an epsilon of 0.9, or an alpha-to-epsilon ratio of 0.11.

Book Description
Progress in Astronautics and Aeronautics, Volume 18: Thermophysics and Temperature Control of Spacecraft and Entry Vehicles is a selection of technical papers based on two American Institute of Aeronautics and Astronautics meetings, namely, The Thermophysics Specialist Conference, held in Monterey, California on September 13-15, 1965 and the Third Aerospace Sciences Conference, held in New York on January 1966. This book covers the most important problems of thermophysical research and technology. This volume is composed of six parts encompassing 42 chapters. Part I contains papers on the thermal radiation properties of solids, including measuring techniques for solar reflectance and infrared emittance determination, and a paper on radiative transfer. Part II deals with the lunar and planetary thermal environment and includes research papers on emissivities, reflectivities, and polarization by planetary atmospheres and planetary surfaces. Part III discusses the effects of the space environment on the optical properties of thermal control surfaces. This part also presents results of flight experiments with sensors of environmental effects and flight experience with thermal coatings of satellites. Part IV covers the thermophysical measurements of ablative materials and with the char layers formed during the actual vehicle entry period or during laboratory simulation tests. Part V looks into the two comparatively areas of thermophysics, namely, the thermal similitude (thermal modeling) and interface resistance of joints under space conditions. Part VI summarizes the practical experience in thermal design gained on spacecraft flights. Thermophysicists, space engineers and designers, and research workers who are interested in thermophysical technology will find this book invaluable.

Book Description
Thermophysics: Applications to Thermal Design of Spacecraft is a collection of technical papers presented at the American Institute of Aeronautics and Astronautics's 7th Aerospace Sciences Meeting, held on January 20-22, 1969, in New York and 4th Thermophysics Conference, held on June 16-18, 1969, in San Francisco, California. Contributors explore the applications of thermophysics to thermal design of spacecraft and tackle topics ranging from conduction and radiation to convection, phase change, and thermal design techniques. Comprised of 26 chapters, this volume begins with a discussion on experimental thermophysical properties, focusing on topics such as contact thermal resistance theory and experiment; optics and engineering in thermophysics; and crystal growth during melting and freezing and its application to phase change in thermal control. The physical parameters affecting radiation property degradation under simulated space environmental conditions are also considered. Radiative analysis is treated in the next section, with emphasis on surface effects upon radiative properties; two-component heat pipes; parametric thermal control requirements for future manned spacecraft; and thermal considerations of a landed vehicle on the surface of Mars. This book should be of interest to practitioners in astronautics and aeronautics.

Book Description
Thermal control is necessary to assurance the optimum performance and accomplishment of the operation because if a component is subjected to temperatures which are too high or too low, it could be damaged or its performance could be rigorously affected. Almost all sophisticated equipment has specified temperature ranges in which it will function correctly. The role of the TCS (thermal control systems) is therefore to maintain the temperature and temperature stability of every item onboard the spacecraft within those pre-defined limits during all mission phases and thereby using a minimum of spacecraft resources. Spacecraft Thermal Control reviews the design drivers and the technologies currently used for spacecraft thermal control focusing on future technology developments in thermal control. It includes thermal environments and design techniques for interplanetary spacecraft, as well as the Earth-orbiting satellites. The readers will find a modernized depiction of the thermal environment in Earth orbit, new material documenting the environments of interplanetary missions, further practical information about the thermal control of hardware elements, and presentation of some newer technologies such as heat switches and precision temperature control techniques. Definitive chapters focuses on correction method for a spacecraft thermal model, architectural design criteria for spacecraft; heat pipe for aerospace applications and testing of a low-cost loop heat pipe design; anodic coating characteristics of different aluminum alloys for spacecraft materials applications; failure detection in an annular combustion chamber with experimental and numerical methods; resolving the difficulties encountered by JPL interplanetary robotic spacecraft in flight; and more.This practical handbook provides the reader with enough background and specific information to begin conducting thermal analysis and to participate in the thermal design of spacecraft systems.
