β角是航天器热控制设计中关键的设计参数,本文通过对阿尔法磁谱仪(AMS)在国际空间站上两年的运行结果进行分析得出,AMS外部温度变化受β角影响很大,PORT侧和STBD侧尤为明显,且呈近似相反的变化规律,而主散热板温度分布相对均匀.β角对AMS热系统的影响规律可以为AMS热控系统监测和近地轨道航天器热控制设计提供参考.
The β angle is one of the key parameters in the design of spacecraft thermal control system.The analysis in this paper is based on the experimental data of alpha magnetic spectrometer (AMS)which has been operational on the international space (ISS) station for more than two years.The results shows that AMS external temperature is greatly affected byβ angle,especially on the PORT and STBD side,on which it appears approximately opposite variations,while the main radiators keep a relatively uniform temperature distribution.The influences of β angle on AMS thermal control system provide a valuable reference for the future AMS thermal control system monitoring and near-Earth spacecraft thermal control system design.
