摘要
地月远距离逆行轨道(DRO)在月球探测、地月空间开发等任务中具有重要价值。针对地月DRO的脉冲调相机动问题,提出了直接调相和间接调相两种调相方法。首先,通过数值方法构建了地月DRO直接调相策略的可行集,分析了调相机动起点和终点位置选择对调相性能的影响,得到了双脉冲最优和次优调相机动策略。针对相位差较大的调相问题,进一步提出了双脉冲弧段组合调相策略。其次,利用地月平动点周期轨道及其同宿、异宿转移轨道,构造了地月DRO间接调相方法,并分析了不同雅可比常数下间接调相策略的燃耗和飞行时间。最后,分析对比了间接调相轨道与直接调相轨道的性能,给出了两者的适用条件。研究结果将为地月DRO的广泛应用开发提供理论基础。
Cislunar distant retrograde orbit(DRO)is of great value for lunar exploration,cislunar development and other missions.Aiming at the impulsive phasing problem of cislunar DROs,two methods of direct phasing and indirect phasing are proposed.Firstly,feasible sets of direct phasing strategy of cislunar DROs are constructed by numerical method,and the influence of starting and terminal points of phasing orbits is analyzed.Then,the optimal and sub-optimal two-impulse phase strategy are obtained.A combined phasing strategy,composed of several two-impulse phasing arcs,is proposed for phasing missions requiring a large phase difference.Secondly,the indirect phasing method of cislunar DRO is constructed by using the lunar libration point orbit and its homoclinic and heteroclinic transfers.Fuel consumption and time of flight of indirect phasing orbits with different Jacobi constants are analyzed.Finally,performances of direct and indirect phasing orbits are analyzed and compared.Several recommendations for their applicable conditions are given.The results provide a theoretical basis for the application of cislunar DROs.
