THERMAL CONTROL COATINGS - AN ANALYTICAL TREATMENT.
Abstract
The need for various types of thermal control coatings has been derived and summarized from an analysis of selected thermal problems frequently encountered in spacecraft hardware coupled with an analysis of variance in the parameters of the thermal balance. This overall analysis indicates the need for a complete series of stable coatings each having a minimum (0.1 or lower) solar absorptance but with different or controllable values of infrared emittance ranging from 0.3 to 1.0 in order to cover the entire range of desirable solar absorptance/emittance ratios from 0.1 to 0.3. This analysis was applied only to a generalized earth orbiting spacecraft. Where internal heat dissipation rates exceeded several watts/sq. ft., active heat removal systems would be required.
