摘　　要：借鉴“东方红3号”卫星的推进系统组成和“SMART-1”探月器的飞行轨道,提出了2种微波等离子体推力器(MPT)应用于月球探测器的推进系统方案(即复合推进方案和统一推进方案),分析计算了MPT用于姿态控制时对推进剂耗量的影响及用于主推进变轨时推进剂耗量和飞行时间的变化,并讨论了MPT的电源系统带来的附加质量。结果表明,在付出一定飞行时间代价的条件下,MPT的引入将大大增加有效载荷质量。According to propulsion system of DFH-3 satellite and flight orbit of SMART-1 lunar detector, two propulsion system schemes which apply microwave plasma thrusters （MPT） to lunar detector were put forward, i, e. compound propulsion scheme and unified propulsion scheme. The influence on propellant consumption was analyzed when MPT was used for attitude control, moreover the change of propellant consumption and flight time was calculated when MPT was used for orbit transfer. The additional mass of the power supply of MPT was discussed. The results show that at the cost of much more flight time, the mass of payload can be greatly increased due to application of MPT.
