环月远程快速交会任务规划

摘要

Co⁃ellipse fast rendezvous strategy was presented as the standard strategy for the remote rendezvous between the lunar module and the command and service module around the moon in a manned landing and return mission. Fuel⁃optimal co⁃ellipse fast rendezvous strategy considering the constraints of total rendezvous time, maneuver time interval and fuel⁃optimal efficiency, and time⁃optimal co⁃ellipse fast rendezvous strategy considering the constraints of total velocity increment, ma⁃neuver time interval and time⁃optimal efficiency, were introduced. Several numerical simulations were conducted to test the feasibility and precision of the standard, fuel⁃optimal and time⁃optimal co⁃ellipse rendezvous strategies. Analysis of the relationship between the total velocity increment and the rendezvous time was also conducted to confirm the feasibility of the optimal strategies.%针对载人登月返回任务中月面上升舱与指挥服务舱的环月远程快速交会问题，以共椭圆快速交会策略为标称策略，并给出摄动模型下的修正方法。给出考虑总交会时间约束、机动时间间隔约束和燃料优化效率的燃料最优共椭圆快速交会策略，以及考虑总速度增量约束、机动时间间隔约束和时间优化效率的时间最优共椭圆快速交会策略。通过算例仿真验证了共椭圆快速交会策略的可行性以及摄动模型下的交会精度，对共椭圆快速交会策略的总速度增量与交会时间的关系进行分析，并对比燃料最优和时间最优共椭圆快速交会对接策略，证明了优化策略的有效性。
