【摘要】：20cm离子推力器在SJ-9A新技术试验卫星上的飞行试验已经结束,为了检验飞行试验的有效性,十分有必要对离子推力器在轨工作性能进行全面分析评价,以便为后续空间应用提供依据。利用在轨获得的试验数据对离子推力器主要工作参数进行了分析,并通过与地面试验数据进行对比,系统性的评价了其工作性能。评价结果表明,在整个飞行试验期间离子推力器各项工作性能参数符合设计指标要求,其中推力在38~39.2m N,比冲在2900~3200s,功耗小于设计值1080W。飞行数据与地面试验数据吻合很好。
[Abstract]:The flight test of 20cm ion thruster on SJ-9A new technology test satellite has been completed. In order to test the effectiveness of flight test, it is necessary to analyze and evaluate the in-orbit performance of ion thruster in order to provide the basis for subsequent space applications. The main working parameters of the ion thruster are analyzed by using the test data obtained in orbit, and the working performance of the ion thruster is systematically evaluated by comparing it with the ground test data. The evaluation results show that the working performance parameters of the ion thruster meet the design requirements during the whole flight test, in which the thrust is 38 鈮，
