基于液相污染模型的航天器交会对接羽流污染研究

航天器交会对接任务一般由主动对接方和被动目标配合完成，交会对接飞行的主动寻的段和分离撤离段均可能出现主动对接方开启反向发动机进行反向紧急制动和撤离的情况，该情况下被动目标可能受到来自主动方反向发动机羽流污染影响。文章利用国际空间站羽流污染计算模型对交会对接任务羽流污染沉积进行了分析计算。

Thruster Plume Contamination in Spacecraft Rendezvous and Docking Mission Based on Liquid-phase Model

The spacecraft rendezvous and docking mission consists of one pursuit spacecraft and one target spacecraft. In the condition of brake or leave maneuver, there will be some plume contamination jetted from the thrusters of the pursuit one. Some sensitive apparatus of the target spacecraft could be affected by the contamination and their performance would also be damaged. This paper has introduced the bipropellant liquid-phase plume contamination model of International Space Station to analyze the mount of contamination in the rendezvous and docking mission. The method of this study could help to improve feasibility of the mission.
