摘要
主流空间电推进系统目前均以氙气作为工质,但价格昂贵和储量不足是氙气工质应用的受限因素。作为可替代氙气的新型推进剂,碘工质在空间电推进技术中的应用已发展至工程阶段。通过分析碘工质在霍尔推力器和射频离子推力器中的应用,分析碘工质空间电推进的推力器设计、贮供系统设计、羽流与航天器兼容和试验设备防护等关键技术,为碘工质空间电推进系统的优化设计提出建议。
Main space electric propulsion systems usually uses xenon as propellant.However,it’s limited by insufficient reserves and expensive price.As a new alternative propellant,iodine electric propulsion system has developed to the stage of engineering.By summarizing iodine hall thruster and iodine radio-frequency ion thruster,key technologies of iodine space electric propulsion are analyzed in the paper,including design for thruster and feed system,compatibility of plume and spacecraft and protection of test equipments to provide advices for optimization design of iodine space electric propulsion system.
