载人飞船再入大气层的最优轨迹与制导研究

Optimal Trajectory and Guidance Law of Manned Spacecraft in Reentrying Atmosphere

研究了载人飞船以弹道一升力方式再入大气层的最优轨迹和最优反馈增益的基准轨道制导法、组合快速预报法，对两种制导法进行了比较，从而得出了几个重要结论。

The paper studies optimal reentry trajectories of manned spacecraft,the guidance using nominal trajectory with optimal feedback gains, guidance using compound fast-time predicting , and compares the two kinds of guidance methods.Some important conclusions are obtained .
