载人登月地月转移轨道快速设计及特性分析

摘要

The constraint conditions for manned lunar mission trajectory design are analyzed, and the earth-moon transfer trajectory model is established. Based on this, a trajectory design method is given, in which the leaving-earth orbit parameters are used as design variables. Combined with the ephemeris, the earth-moon transfer trajectory scheme that satisfies the manned lunar mission constraints is reached, and the orbit characteristics are analyzed. Simulation results indicate that the method which does not need trajectory integral is rapid and highly accurate in calculating. It is useful for the analysis of the earth-moon transfer trajectory.%分析了载人登月轨道设计的约束条件，在此基础上建立了地月转移轨道设计模型，给出了一种以地球出发轨道参数作为设计变量的轨道设计方法，结合月球星历得到了满足载人登月任务约束的轨道方案，并对载人登月任务地月转移轨道的工程特性进行了分析。此方法是一种无需轨道积分的纯代数计算方法，具有速度快、精度高的特点，其顺行求解的思路，可对载人登月轨道方案制定阶段的轨道特性做出有效分析。
