一种兼顾不同轨道姿态的卫星热控优化设计方法

分析了传统卫星的热控设计方案,提出一种能够同时满足太阳同步轨道和倾斜轨道条件的卫星热设计优化方法.基于该优化方法对某卫星在两种轨道条件下进行了热仿真分析,并对太阳同步轨道条件下的卫星进行热平衡试验和在轨验证.研究结果表明,采用该优化方法可减少倾斜轨道条件下卫星热设计的地面试验验证,缩短卫星研制周期并显著节约成本.研究结果可为卫星热控设计优化提供参考. 

A Balanced Satellite Thermal Control Optimization Method for Different Orbit and Attitude

Based on analysis of the thermal control design of traditional satellites,an optimization method for satellite thermal design which is applicable to both Sun-synchronous orbit and lowinclination orbit is presented.Using this optimization method,thermal simulation analysis is made for a satellite under both orbit conditions,and the satellite thermal balance test and in-orbit validation are conducted for the Sun-synchronous orbit.Combined with thermal simulation results,it is shown that the thermal design of low-inclination orbit satellite conditions can reduce the ground test verification,shorten the satellite development cycle and save the costs significantly.This research work can provide reference for the design optimization of satellite thermal control.
