本文以同步轨道卫星完成轨道控制功能所采用的单元肼推进系统作为比较基准,对单元肼推进系统加上南/北位置保持用的增强型肼催化推力器(简作ACT)组成的混合推进系统以及双元推进系统进行了分析比较。分析结果表明,单元肼/ACT混合推进系统和双元推进系统二者在重量上相当,这两种推进系统比单元肼推进系统可节省重量18％。 In this paper, a hybrid propulsion system consisting of a hydrazine catalytic thruster (ACT) for unit hydrazine propulsion system plus south / north position maintenance is used as a baseline for the hydrazine propulsion system of a unit that uses orbiting satellites to perform orbit control functions As well as the dual propulsion system was analyzed and compared. The results of the analysis show that both the hydrazine / ACT hybrid propulsion system and the binary propulsion system are comparable in weight, and both propulsion systems save 18% of the weight compared to a unit hydrazine propulsion system.
