摘要:
采用基于电推进的空间运输系统(转移级)完成使命,相对于采用化学推进可节省大量的推进剂,能够显著降低航天器的发射重量或者把更多的有效载荷送达探测目标地。调研了国外大功率电推力器的研究情况,针对近地空间的大功率轨道转移航天器任务需求,给出了电推进系统方案设计,并对采用不同性能指标推力器的多种方案进行对比,得到综合最优的方案。最后针对我国电推进技术发展现状,给出了我国大功率电推力器的关键技术和发展建议。

Abstract:
Compared with chemical propulsion,the application electric propulsion system in spacecraft can save the amount of propellant,which is able to significantly reduce the launch mass or allow more payloads to the target. In this paper,the research on high power electric thrusters in the world is investigated. An electric propulsion systemis designed for the near-earth spacecraft orbit transfer. Several schemes are compared with different thruster performances. At last,the suggestions are proposed for developing high power electric thruster and propulsion system in China.
Key words:  high power;electric propulsion;orbit transfer
