Study on Space Test of Electric Propulsion System

电推进系统的相容性、空间推力/比冲等是空间应用关注的重要性能指标。根据电推进系统未来空间试验技术发展趋势,调研了国内外离子、霍尔电推进系统的推力、电磁兼容性、对卫星的污染等空间试验情况,结合我国电推进系统首次开展空间试验现状、电推进系统的布局,以及星上配备的卫星污染与电位监测器,对空间环境条件下卫星的污染、电推进自身及卫星设备的电磁兼容性、空间推力标定方法、推进剂剩余量分析方法等进行了研究。通过电推进系统在轨连续试验、电推进羽流影响等分析,得到电推进对卫星周围污染情况、电推进与卫星平台的电磁兼容性等在轨性能参数,可为全面评价电推进系统技术、科学制定电推进空间试验计划及电推进空间应用提供依据。

Electromagnetic compatibility（EMC）, space thruster and specific impulse are the most important performances of an electric propulsion system in space applications. Based on the future development trend for space test of electric propulsion, the space tests of thruster, EMC and con- tamination on satellite are investigated for ion and Hall electric propulsion systems. The first space test of electric propulsion has been carried out in China. In combination of the first space test result, the layout of electric propulsion system and the set-up of monitor on pollution and voltage in the satellite, the pollution degree of electric propulsion to satellite, the EMC between electric propulsion system and satellite platform, the thruster calibration methods in space envi- ronment, and the analysis methods of residual propellant are researched in this paper. The test results and the effect of the electric propulsion plume are analyzed. The information on the elec- tric propulsion pollution, EMC and other in-orbit performances are achieved. The research re- sults can provide the basis for assessing electric propulsion system, making electric propulsion space test plan and promoting electric propulsion in space application.
