Book excerpt: This paper presents an evaluation of several silicone resin binders and powdered inorganic pigments for potential use in spacecraft thermal-control paint formulations. The pigments were selected on the basis of a hypothesis relating the heat of formation of a compound to the compound's resistance to ultraviolet-radiation-induced degradation. Reflectance measurements were made in situ to determine degradatiorna tes due to ultraviolet radiation. The tested polydimethylsiloxane resins were not significantly affected by long exposures to ultraviolet radiation. All the pigments, which were dispersed in a polydimethylsiloxane resin, were degraded by ultraviolet radiation as determined by an increase of solar absorptance. For the materials evaluated in this study, no evidence was found to indicate that pigments with high heats of formation were resistant to ultraviolet degradation.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Aeronautics, Volume 20: Thermophysics of Spacecraft and Planetary Bodies: Radiation Properties of Solids and the Electromagnetic Radiation Environment in Space is a collection of technical papers drawn mainly from the American Institute of Aeronautics and Astronautics Thermophysics Specialist Conference, held in New Orleans on April 17-20, 1967. This volume is organized into six part encompassing 45 chapters that offer a selection of the most advanced studies in the dynamic field of thermophysics. Part I deals with radiation properties of solid state materials and the measuring techniques in the laboratory, while Part II describes the thermophysical properties of surfaces used for spacecraft. The papers of Part II also include solid state physics studies of the processes involved in the interaction of UV radiation with solids. Part III discusses the results of thermal flight experiments and on the radiation characteristics of planetary bodies, followed by topics on general radiative properties and the measurements of radiative properties of natural surfaces from satellites in Part IV. Part V contains papers on thermal similitude and on the closely related subject of radiant heat transfer analysis of thermal systems. Lastly, Part VI focuses on the heat transfer within the spacecraft under the conditions of space environment, specifically conductive and radiative transfer. This book is of great value to thermophysicists, space engineers and designers, as well as researchers in the fields of astronautics and aeronautics.

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the XXth International Astronautical Congress compiles selected papers presented at the 20th International Astronautical Congress held in Mar del Plata, Argentina in 1969. This book is divided into five main topics—spacecraft engineering, astrodynamics, astrionics, bioastronautics, and problems of education. In these topics, this compilation specifically discusses the equatorial vibrations of a long flexible boom on a spin-stabilized satellite of non-zero radius; heat transfer to linear bodies in two-dimensional hypersonic low density; and limits of accuracy of general perturbations for satellites moving under constant forces. The rapid optimization of multiple-burn rocket flights; data transmission for planetary studies; and comparison of theoretical and experimental attitude data for the DODGE spacecraft are also elaborated. This text also covers the Apollo life-support and protective systems; bioastronautical aspects of Apollo biomedical operations; and development and applications of hot water rockets. This publication is recommended for astrophysicists and scientists of other disciplines related to astronomy.
