Abstract
A thermal analysis is performed to investigate the thermal behaviour of the deployed solar array of the Communications Technology Satellite (CTS). Continuum theory is used to derive equations for the temperature distributions on both the blanket and BI-STEM boom of the solar array, and the resulting set of coupled integro-differential equations is solved numerically by computer. The expected flight temperature profiles are given, and the thermal bending moments which arise in the BI-STEM boom, and which cause thermal distortion of the solar array, are computed and are found to be small. It is concluded that thermally induced variations in position of the solar array from that at static equilibrium will be of inconsequential magnitude.
