摘要
Abstract
An Earth-original sunshine orbital coordinate system is defined.In this coordinate system,the complex computation of the relative position between satellite and the Earth can be bypassed,so the calculations of related angles in satellite orbital heat flux analysis become simple,and the satellite thermal analysis can be quickly accomplished.A thermal network model of a six-prism shaped satellite is built.The orbital heat flux on the surfaces of the satellite is simulated and applied in the model to obtain the satellite internal temperature at the start and end of eclipse period.Based on the model,an optimization of thermal control system to minimize multi-layer insulations mass in limitation of the satellite internal temperatures between-10℃ and +35℃ in both cold and hot cases is established.Multi-layer insulations thickness and radiator window area are optimized.关键词
