为了验证霍尔电推进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,LHT-100霍尔电推进系统搭载SJ-17新技术验证卫星开展了在轨飞行试验,对霍尔电推进系统在轨飞行试验结果进行了详细评价。结果表明:在整个飞行试验期间LHT-100霍尔电推进系统各项工作性能参数符合设计指标要求,其中推力79.5m N,比冲1531s,系统功率低于1.527k W,单次长时间工作8h,在轨系统开关机次数大于24次,在轨累计点火时间超过3028min,在轨飞行试验数据与地面试验数据具有很好的一致性。
In order to verify the adaptability of the space environment of the Hall electric propulsion system, the mutual compatibility with the spacecraft, the characteristics of the space operation and the difference of the space flight performance and the ground data, the LHT-100 Hall electric propulsion system is equipped with the SJ-17 new technology verification Satellites in orbit flight test conducted on the Hall electric propulsion system in orbit flight test results were evaluated in detail. The results show that the performance parameters of LHT-100 Hall electric propulsion system meet the design requirements throughout the flight test. Among them, thrust of 79.5 m N, specific impulse of 1531s, system power of less than 1.527kW and single long time operation of 8h , The number of on-orbit system on-off was more than 24 times, and the cumulative ignition time on the track exceeded 3028min. The on-orbit flight test data had good consistency with the ground test data.
