ENVIRONMENTAL CONTROL STUDY OF SPACE VEHICLES (PART 2). THERMAL ENVIRONMENT OF SPACE
GENERAL DYNAMICS CORP POMONA CA POMONA DIV
A prerequisite to the development of a system for the thermal control of a space vehicle is a clear and complete definition of the heat sources and sinks in space, and the modes and magnitudes of heat transfer. The study presented is intended to provide this information, based upon the most reliable data available. The curves and tabulated data given provide a complete mapping of the space thermal radiation environment throughout the solar system. Direct solar radiation, planetary albedo, and planetary thermal radiation are considered for vehicle surfaces of spherical, hemispherical, cylindrical and flat plate configurations. By combining these shapes andor building up a composite of flat surfaces, heat incident to space vehicles of any configuration, located anywhere in the solar system can be obtained. For convenience, the bulk of the data is given in curve form in Supplement A AD-276 854 for hand computation and comparison purposes and in tabular form in Supplement B AD-276 855 for use as automatic digital computer data input.
