摘要
本文以某型号通信卫星多重叠可展开固面天线反射器的温度控制要求为基础,在充分考虑传统反射器热控方案的情况下提出了两种改进型的热控方案,并数值对比分析了传统热控方案和两种改进型热控方案对反射器的在轨温度控制能力,指出了两种改进型热控方案的优缺点和适用性,对反射器的热控设计起到指导作用。
In recent years,the overlapping antennas are used more and more on DFH-4 platform to improve satellite communication capacity and efficiency.As one of the most important components,the reflector must maintain sufficient accuracy and reliability in the severe space environment.Based on traditional thermal control scheme,two improved thermal control methods are proposed in this paper.Meanwhile,numerical analysis and comparison of these methods are carried out,which can play a guiding role in the thermal design of overlapping reflectors.
