| 摘 要： | 以最小燃料消耗量为性能指标，考虑了多种约束条件(过载、动压、加热率等 )，采用了组合优化方法对空天飞机上升轨迹进行优化。该组合优化算法包括静态参数与动 态参数优化方法。其中，静态参数优化算法采用了全范围搜索方法，动态参数优化算法包 括动态规划法与共轭梯度法。通过数值仿真计算，得到飞行分离状态数据及相应的最 优 上升轨迹。数值仿真表明，该组合算法对航天器轨迹优化具有良好的适用性及实际工程价 值。

| Abstract: | The ascent trajectory of TSTO space plane is optimized by a combined optimization algorithm. This combined algorithm includes static parameter optimization and flight control variables optimization. The static parameter algorithm is the method that uses entire scope searching. The flight control variables are optimized by two methods,dynamic programming and conjugate gradient. The performance index is to minimize fuel consumption of the TSTO space plane,considering the constraints such as overload,dynamic p... |
