摘要
目的预估空间站在轨期间遭受的原子氧撞击通量。方法通过对空间站构型进行建模,轨道、姿态参数设定,应用Kepler计算方法对空间站在轨20年的原子氧积分通量进行初步的仿真计算和分析。结果得到了航天器各个微元表面的原子氧积分通量数据。结论通过数据分析可知,迎风方向上经受的最大原子氧通量达到5.79×1022atoms/cm2,综合空间站各个不同位置表面的积分通量数据,可为航天器结构设计与材料选择提供技术支持。
Objective To predict the AO ram flux of the space station on the orbit. Methods Through modeling of space station configuration and setting of orbit/attitude parameters, preliminary simulation calculation and analysis were performed for the AO ram flux of the space station on the orbit for 20 years using the Kepler calculation method. Results AO ram flux data all over the spacecraft was obtained. Conclusion Through data analysis, it was revealed that the maximum AO ram flux reached up to 5. 79×10^22 atoms/cm^2. The ram flux data at the surface of different positions of the ISS could provide technical support for the configuration design and material selection of the spacecraft.
