摘要
基于飞行力学、最优控制理论、最优化方法，采用两种轨迹／飞行器总体参数的一体化优化方法──静态＋动态一体化优化方法和参数最优化方法，研究载人飞船再入的轨迹／总体参数的优化，并比较了两种一体化优化方法的不同特点。通过数字计算，得到飞船的最优滚转程序、升阻比、再入角和再入终端时间。结果分析表明，两种一体化优化方法都能得到较高精度。
Based on the theories of flight dynamics, modern control theory and optimization method, using two integrated optimization methods of trajectory/vehicle overall parameter-static state+dynamic state integrated optimization method and parameter optimization method, optimization of reentrying trajectory/overall parameter of manned spacecraft is studied. And also the characteristics of the two integrated optimization methods are compared. Using numerical calculation, optimal roll program, the ratio of lift and drag, reentry angle and reentry time of spacecraft are gotten. From the analyses of the results, it states that the two integrated optimization method can get good calculating accuracy.
