载人月面着陆器贮箱热控方案分析

Analysis on Thermal Control Scheme of Manned LunarLander Tank

针对月球表面低温、高温热环境与地月转移过程空间深冷环境,提出了多种载人月面着陆器贮箱热控方案,对不同热环境下的不同热控方案进行仿真计算,得到了载人月面着陆器侧壁与贮箱温度变化趋势。结果表明:3种方案中,方案一系统代价最低,为最优方案;贮箱通过被动热控设计可以使温度满足任务要求,且不需要增加额外代价。

A series of lunar lander thermal control schemes were proposed according to the low temperature and high temperature thermal environment on the lunar surface as well as the space cryogenic environment.Different thermal control schemes under different thermal environments were simulated and the temperature variation trends of side wall and tanks were obtained.The results showed that among the three schemes discussed in the article,the system cost of scheme 1 was the lowest and scheme 1 was the optimal scheme;through passive thermal control design,the temperature of the storage tank could meet the task requirements without additional cost.
