【摘要】 为了实现艰巨和复杂的空间探测任务并降低其巨额费用,需要解决高效的运输系统。本文讨论了除改善现用化学推进系统性能外,采用高比冲电火箭发动机担负探测器主推进的优越性。文中还简要地介绍了目前采用太阳电推进系统作主推进的DS-1、MUSES-C和SMART-1三个空间探测器的证实飞行试验情况和结果。最后,指出了空间探测器主推进用电火箭的发展趋势。更多还原

【Abstract】 In order to carry out the difficult and complex space exploration mission and reduce the cost, it is necessary to develop the high-efficient transportation system. This paper discusses the advantage using high specific impulse electric rocket as primary propulsion of spacecraft. The status and results of flight demonstration test about DS-1、MUSES-C 和 SMART-1 spacecraft used solar-electric propulsion system as primary propulsion is also presented simply in the paper. At the end, the development trend of electric rocket for future solar system exploration mission is pointed out.更多还原
