月球探测器电推进系统的应用研究

Application of an Electric Propulsion System to a Lunar Detector

介绍了月球探测器推进系统概况,比较了国外两种典型月球探测器电推进系统。在我国首个月球探测器"嫦娥1号"推进系统基础上,参考日本LUNAR-A月球探测器、欧洲SAMART-1月球探测器的推进系统组成,提出一种月球探测器电推进系统方案。对该方案进行了初步的分析计算,结果表明了该方案的可行性以及可实现降低推进剂消耗量、增加有效载荷的优越性。

To reduce the launch cost of a lunar detector, increase its available payload and promote China＇s electric propulsion for space applications,the lunar detector propulsion system is studied and two typical electric propulsion systems of other country＇s lunar detectors were compared. An electric propulsion system scheme for lunar detector is presented on the basis of the propulsion system of Chinese ＂ Chang E-1＂ lunar detector and with reference to the Japanese LUNAR-A lunar detector and the European SMART-1 （ Small Mission for Advanced Researching Technology） lunar detector propulsion system. Preliminary analysis and calculation results show that this scheme is feasible with the advantage of reducing its propellant consumption and increasing its available payload.
