实现推进剂的在轨加注服务能够显著提升大规模空间探测能力、减小运载器规模、降低任务成本.归纳常规推进剂在轨加注方案并进行分类和比较,对国外典型的常规推进剂在轨加注研究计划进行分析,总结其发展趋势,为后续深入开展相关研究工作提供参考.%The realization of orbital refueling service for spacecraft can significantly improve the ability of large scale exploration missions, reduce the takeoff weight and dimension of the launch vehicles and aerospace vehicles, and reduce the exploration cost. In this paper, orbital refueling schemes for storable propellants are induced, classified and compared. The representative orbital refueling research programs of USA are analyzed, and the development trends are summed up, which provides reference for future in-depth research.
