Abstract:

The Wright Research and Development Center WRDC and the Arnold Engineering Development Center AEDC have initiated a program for measuring optical and radiative effects of satellite material outgassing products on thermal control and cryo-optic surfaces. A solar absorptance chamber for making reflectanceabsorptance measurements on thermal control materials has been established. This report describes the operation of the solar absorptance chamber used to measure the degradation of reflective surfaces and solar cells caused by deposition of outgassing contaminants. The effects of solar irradiation UV were also studied, and results are presented. Data are presented for Dow Corning 93-500 Space-grade encapsulant DC93-500, Furane Products Uralane 5753-ABLV encapsulant, and Polyclad FR-4 Epoxy laminate.
