摘要： 基于光谱卫星任务需求,兰州空间技术物理研究所开展了脉冲等离子体微电推进系统方案设计,以此完成25W级脉冲等离子体电推进系统飞行样机研制,并开展了地面各项测试,均满足需求。为了进一步验证该系统的空间环境适应性、与航天器的相互兼容性、空间工作特性及空间飞行性能与地面数据的差异性,LPPT-25微电推进系统搭载长光卫星公司光谱星一号（GP-1）卫星开展了在轨飞行试验,对脉冲等离子体电推进系统在轨飞行试验结果进行了评价。结果表明：在整个飞行试验期间,脉冲等离子体电推进系统各项工作性能参数符合设计指标要求,电推进分系统工作正常,推力输出稳定,各遥测温度满足推进要求的控温范围;电推进推力标定为306.3 μN,相比地面测试推力300 μN,偏差在5%以内,体现了良好的天地一致性。
