采用圆锥曲线拼接法,建立了月球垂直着陆的数学模型;推导了地月转移轨道和一些重要参数的初步设计和计算方法。通过仿真,给出了理想情况下和考虑推力大小时月球垂直着陆轨道运动特性。对运动特性的分析结果可为轨道初步设计提供一定的参考。
The conical curved stitching method is used to establish the mathematical model of lunar vertical landing. The preliminary design and calculation method of the lunar-moon transfer orbit and some important parameters are derived. Through the simulation, the trajectory characteristics of the vertical landing orbit of the moon under ideal conditions and considering the thrust force are given. The results of the analysis of the motion characteristics can provide a reference for the preliminary design of the orbit.
