基于双二体模型的载人登月着陆点选取分析与仿真

Analysis and Simulation of Landing Site Selecting for Manned Lunar Landing Mission Based on Double Two-body Model

载人登月的着陆点选取研究,对于今后实施载人登月以及全月面到达的研究很有意义。而载人登月着陆点的选取又涉及到多种约束,只是选取燃料和驻留时间两个约束对相关着陆点进行建模分析和仿真。本文首先对月球相关几何关系进行研究,基于双二体模型对月面着陆点选取与停留时间关系进行研究;其次根据能量消耗和地月转移轨道倾角约束考虑了三种不同的着月和上升策略,对三种不同策略的着月点和停留时间进行数学建模;最后,通过仿真,总结得出载人登月月面着陆点选取与燃料和驻留时间的关系。

Landing site selecting for manned lunar landing is very meaningful to research manned lunar landing mission and global access and anytime return from the lunar surface in the future. The selection of manned moon landing site involves a variety of constraints, Fuel and dwell time two constraints are selected only on landing mod- eling analysis and simulation. First, Geometric relationship related to the moon is studied, based on double two- body model the relationship between surface site selection and retention time are researehed. Secondly according to the energy consumption and transfer to the moon orbit angle constraint considering three different kinds of the land- ing and rising strategy. In three different strategies of the mathematical modeling on landing site and residence time. Finally, simulation, and summarizes the relationship landing site selecting for manned lunar landing mission and fuel and residence time.
