推进系统作为月球探测器的关键分系统,为探测器在轨任务各阶段提供轨道机动的速度增量,为探测器姿态调整提供控制力矩,为月球软着陆时探测器悬停、避障和月球轨道交会对接提供所需的平移推力。推进系统能否正常、可靠地工作,对探测器任务的成败起到至关重要的作用。此外,推进系统性能的优劣决定了探测器 The propulsion system, as the key subsystem of lunar probe, provides the incremental velocity of orbital maneuver for each phase of the orbit mission of the detector, provides the control moment for attitude adjustment of the probe, hovers, avoids obstacles and the moon when the moon landed softly Rail rendezvous docking provides the required translational thrust. Whether the propulsion system can work normally and reliably plays a crucial role in the success or failure of the detector mission. In addition, the pros and cons of advancing system performance determines the detector
