電推進羽流與航天器相互作用的研究現(xiàn)狀與建議

A review of the researches of interaction between electric propulsion plume and spacecraft

摘要: 電推進與傳統(tǒng)的化學推進相比可以節(jié)約大量推進劑質量，被廣泛用作地球同步軌道衛(wèi)星南北位置保持和深空探測等任務的主推進系統(tǒng)。電推進器工作時產生的羽流與傳統(tǒng)的化學推進器羽流有顯著區(qū)別，電推進羽流對航天器的影響是進行衛(wèi)星電推進器系統(tǒng)設計時需要重點關注的問題。文章討論了電推進羽流對航天器的主要影響，介紹了國外在地面模擬試驗、空間飛行驗證和軟件仿真技術等方面的研究現(xiàn)狀，同時對國內開展羽流與航天器相互作用研究提出了建議。

Abstract: The electric propulsion can provide a substantial mass saving as compared to the conventional chemical engine. It has been widely used for the station keeping and the primary propulsion of geosynchronous satellites in deep space missions. The plume induced by electric propulsion thruster is quite different from that produced by the chemical engine. The interactions between the electric propulsion plume and the spacecraft must be considered by designers. In this paper, the effects of the electric propulsion plume on the spacecraft are discussed. The related ground simulation test, in-flight test and software simulation are reviewed. Some suggestions are made for the research work in this field in China.
