摘要
本文采用基于多重打靶技术的参数优化方法,以美国航天飞机轨道器为例,选取了几种目标函数和约束条件,对其最佳再入轨迹进行了计算.将计算结果与美国航天飞机的实际再入轨迹作了比较,并对文中采用的算法和程序的适用性进行了小结。
In the paper, a parameter optimization method is used on the basis of the multiple shooting technique to calculate optimal trajectories. Choosing American shuttle orbitor as example, we calculate the optimal reentry trajectories with several performance indices and constraints. The calculated results are discussed comparing with the actual reentry flight trajectory of the shuttle orbitor. The effectiveness of the method and program is summrized.
