| 摘 要： | 本文研究航天器利用气动力辅助变轨实现由远地轨道向近地轨道异面转移问题，就航天器利用大气飞行实现减速及轨道平面机动提出了一种考虑过程约束存在时的优化设计方法。通过方案设计将函数优化问题转换成参数优化问题，并利用美国航天飞机数据进行了模拟计算，得到满意结果。

| Abstract: | In this paper,the problem of aeroassisted return from a high Earth orbit (HEO) to a low Earth orbit with plane change is considered. A new method to optimizethe atmospheric flight together with propulsive maneuver under the consideration of fundamental heating, dynamic and deceleration contraints is provided and the variational problem is reduced to a parametric optimization problem with the help of drag reference profile design.To verify the method, the American space shuttle is taken as an example and the result is satisfying. |
