摘要
为获得电推进系统准确的工作性能,验证其在轨工作稳定性,国内首台空间用氙离子电推进系统于2012年11月~2014年2月在我国新技术试验卫星——实践九号A卫星上开展了首次在轨飞行试验。本文简要介绍了40mN/3 000 s氙离子电推进系统的设计方案和主要性能指标,重点阐述了所开展的系统性能在轨测试内容、测试方法及获得的测试结果,并对测试结果进行了分析,最后给出了在轨测试结论。
To achieve accurate operating performance of electric propulsion system （EPS） and demonstrate its operating stability in orbit, flight tests of Chinese first xenon ion EPS used in space were carried out for the first time at the SJ-9A satellite from November 2012 to February 2014. The design scheme and primary performance index of the 40 mN/3000 s xenon ion EPS are introduced briefly in this paper. The in-orbit performance test contents, methods and results of the system are described emphatically. The achieved test results are analyzed. The conclusions of in-orbit test are brought out.
