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.
建立了用于研究載人深空飛行返回再入模式問題的平面動力學模型,進行了基于彈道式和半彈道式模式再入的軌道仿真,分析比較了相同參數條件下兩種再入模式的軌道動力學仿真結果,得出了載人深空飛行返回應采用半彈道式模式再入的結論,為進一步研究載人深空飛行返回再入策略和軌道優化設計提供了條件。
