基于低地球轨道空间等离子体对航天器的充电机理,根据电子、离子运动性质分析了飞船绝对电位与表面导电材料分布间的关系,讨论了对接放电过程中航天器与空间等离子体的交互作用,给出了其计算方法和相关试验结果。从空间环境角度为工程实现提供了理论依据和参考。
Based on the charge mechanism of the spacecraft with low Earth orbit space plasma, the relationship between the spacecraft absolute potential and the surface conductive material distribution is analyzed based on the electron and ion motion properties. The interaction between the spacecraft and the space plasma during docking and discharge process is discussed. The calculation method and related test results are given. From the perspective of space environment for the project to provide a theoretical basis and reference.
