“神舟七号”飞船热控分系统设计和在轨性能评估

Design and On-orbit Performance Evaluation of Thermal Control System for SHENZHOU-7 Spaceship

针对出舱活动飞船热控设计难点,简要介绍了其热控方案,并对热控分系统在轨飞行数据进行了深入分析,综合评估其在轨工作性能。飞行试验表明,飞船在待发及上升段、自主运行段、出舱活动段、返回再入段,热控分系统均具有良好的温度调控能力和适应能力,整船仪器设备温度及密封舱空气温湿度均满足指标要求。

The on-orbit flight data were analyzed and the operation performance was evaluated. Flight test shows that TCS has excellent temperature adjust and adapt abilities during prelaunch and ascent stages, orbit flight, EVA and reentry phases, and all apparatus temperature, air temperature and air relative humidity meet the technology requirements.
