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(xué)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(shù)條件下兩種再入模式的軌道動力學(xué)仿真結(jié)果,得出了載人深空飛行返回應(yīng)采用半彈道式模式再入的結(jié)論,為進一步研究載人深空飛行返回再入策略和軌道優(yōu)化設(shè)計提供了條件。
