摘要
随着微机电系统技术与超大规模集成电路等技术的迅速发展,小微纳卫星因较低的成本、可完成一定复杂度的任务成为了当前各国商业航天发展的重要方向,小微纳卫星的在轨机动能力需求牵引了系列化微小型电推进系统的研制与在轨搭载验证。本文首先对小微纳卫星任务对电推进系统的需求进行了论证,随后简述了微小型电推进系统的特点,介绍了国内外微小型电推进系统研制与在轨验证情况,最后对国内微小型电推进系统的研制与在轨应用进行了展望。
With the rapid evolution of the MEMS and VLSI technologies,small nano-satellite,being low cost and competent in complicated tasks,has become a crucial orientation of the commercial aerospace in the world.The on-orbit maneuverability ability of the small nano-satellite promotes the serial micro-electric propulsion system′s development and on-orbit verification.In this paper,the demands of the electric propulsion system for the small nano-satellite are firstly demonstrated.Then the characteristics of the micro-electric propulsion system are introduced,including the product engineering and on-orbit verification of the micro-electric propulsion system at domestic and overseas.Finally,the development and on-orbit application of the micro-electric propulsion in China are prospected.
