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。
The constraints of manned lunar orbit design are analyzed. Based on this, a design model of lunar and lunar transitional orbit is established. A trajectory design method based on the orbital parameters of the earth as a design variable is given, which is satisfied by the lunar ephemeris Manned lunar mission constraints of the orbital program, and manned moon landing mission to the transfer of orbit characteristics of the project were analyzed. This method is a pure algebraic calculation method without orbit integral, which has the characteristics of high speed and high precision. The idea of forward solution can effectively analyze the orbit characteristics of manned lunar orbit trajectory planning stage.
