Abstract

This paper presents an approach to the design, analysis, fabrication, and a test of a development model of 100 K passive space radiator for a geostationary meteorological satellite. Significant design considerations include the importance of heat-leak control at low temperatures and the importance of a well devised plan for elimination and control of moisture and contaminants. Fabrication issues include the ability of the design to be compatible with spacecraft assembly as well as to accommodate disassembly for repair or access to the focal plane. The results of a test of the development model are presented. The data correlation process is discussed and the need for a good means of determination of surface properties at cold temperatures is identified. A summary of recommended design and fabrication features is presented.
