Abstract:

Various facets of thermal testing of space vehicles in cold vacuum chambers, with and without solar simulation, are discussed. Emphasis is on thermal modeling of spacecraft. Thermal modeling is discussed for the case of simultaneous preservation of temperature, material and surface properties. The following specific items are treated a criterion for the application of isothermal modeling is developed and illustrated with experimental data, rules for nonisothermal modeling are discussed and illustrated with experimental results, the effect of internal convection is calculated and modeling rules are developed, the effect of internal radiation is discussed and the relative importance illustrated theoretically, and a criterion is developed for the degree of intensity nonuniformity for a solar simulator in terms of desired temperature accuracy.
