摘要
在发射入轨的70颗航天器上发生离子电推进在轨故障的有13颗,总计有29个离子电推进的单机故障。通过对离子电推进在轨故障进行数据统计分析,能够得到航天器应用离子电推进可借鉴的重要工程经验。对离子电推进在轨故障进行了分类统计分析研究,主要包括对航天器影响的故障统计分析、对离子电推进系统影响的故障统计分析、在轨故障发生时间分布的统计分析等方面。
Among 70 spacecraft launched,on-orbit faults of ion electric propulsion occurred on 13 of them,with a total of 29 faults in ion electric propulsion’ s product units. Important engineering experience for ion electric propulsion applied to spacecraft can be obtained based on statistical analysis of these faults. In this paper,on-orbit faults of ion electric propulsions are statistically analyzed,including statistical analysis of their effects on spacecraft and ion electric propulsion systems,and statistical analysis of their time distribution.
