微电推进系统研制及应用现状

Development and Application of Micro-electric Propulsion System

200kg以下的微小卫星的轨道维持、姿态控制、阻尼补偿、编队飞行等任务对微电推进技术及产品提出了明确的应用需求,不同类型的微电推进在不同功率范围内有着各自的优势。本文对中国微小卫星12U立方星LPPT-5脉冲等离子体电推进系统、150kg小卫星LPPT-25脉冲等离子体电推进系统、6U立方星LVAT-1真空弧电推进系统、引力波探测卫星LCT-10胶体电推进系统、低轨小卫星星座LHT-40霍尔电推进系统方案及研制进展进行了论述,最后对正在研制的LRIT-40射频离子电推进系统与LECR-50微波离子电推进系统研制情况及后续应用进行了展望。

Orbit maintenance, attitude control, damping compensation, formation flight and other tasks of micro-satellites under200 kg put forward clear application requirements for micro-electric propulsion technology and products. Different types of micro-electric propulsion have their own advantages in different power ranges. The scheme and development of LPPT-5 pulse plasma electric propulsion system for 12 U standard cubic satellite, LPPT-25 pulse plasma electric propulsion system for 150 kg small satellite, LVAT-1 vacuum arc electric propulsion system for 12 U standard cubic satellite, LCT-10 colloid electric propulsion system for gravitational wave detection satellite and LHT-40 hall electric propulsion system for low orbit small satellite constellation are discussed in this paper. In the end, the recent progress and future application of LRIT-40 radio frequency ion electric propulsion system and LECR-50 microwave ion electric propulsion system are prospected.
