A two-dimensional dynamic model of manned deep space exploration reentry trajectory design was established,and the reentry trajectory simulations based on ballistic mode & semi-ballistic mode were calculated.
建立了用于研究载人深空飞行返回再入模式问题的平面动力学模型,进行了基于弹道式和半弹道式模式再入的轨道仿真,分析比较了相同参数条件下两种再入模式的轨道动力学仿真结果,得出了载人深空飞行返回应采用半弹道式模式再入的结论,为进一步研究载人深空飞行返回再入策略和轨道优化设计提供了条件。
