Abstract:

The thermal control system (TCS) provides effective and stable support to the on-orbit running of the alpha magnetic spectrometer (AMS) running on the International Space Station (ISS). Long-time monitoring of the TCS presents temperature warnings occurred on the circulation box (Box-C) of the transitional radiation detector (TRD), tracker plane 1 and photomultiplier tube of lower time of flight detector in particular cases. The monitoring also presents that the operations of both starboard solar arrays and thermal radiator of the ISS can affect the local temperature of AMS. In this paper, by analyzing the temperature data in different cases, the influence of locking solar arrays of the ISS to the three components mentioned above is given. The most optimized angle factor of the starboard thermal radiator of the ISS reflecting solar irradiation to AMS is calculated, the calculation is verified by actual tests, the analysis of thermal response of the components is given, which indicates the validity of the TCS. Based on the analysis above, the approaches of controlling unusual temperature are proposed, which provides references to the on-orbit thermal control of AMS.

摘要:

热控系统为阿尔法磁谱仪在国际空间站上运行提供了有效和稳定的支持。长时间的在轨运行监测显示,个别工况下,阿尔法磁谱仪的穿越辐射探测器气体循环箱、硅微条探测器第一层和下层飞行时间计数器存在温度预警现象。同时,对国际空间站右舷侧太阳能光伏面板和右舷侧主散热板的操作,可以调节阿尔法磁谱仪的局部温度。通过分析具体工况的温度数据,得到了锁定太阳能光伏面板对上述3处温度的影响,计算了右舷侧主散热板向阿尔法磁谱仪反射太阳热辐射最优辐射角系数,并通过实验验证了计算的正确性,分析了异常温度部件的热响应,证明了已有热控系统的有效性。给出了针对异常温度现象的热控制建议,为阿尔法磁谱仪和其他航天器热控系统设计及运行提供了参考。
