为解决小升阻比月球返回舱再人大气层时安全性低、机动能力差的问题，本文提出采用一种带配平翼的中等升阻比返回舱做为月球采样返回舱,并对动压约束下轨迹优化问题进行了分析。构建一阶状态变量约東最优控制问题模型。然后采用庞德里亚金极大值原理以总吸热量最小为优化目标,对动压约束下再入轨道的初始再入段进行了优化设计,给出了升力系数的最优表达式。在最优轨迹的推导过程中，将问题分为自由段，约束段和自由段，并分别限定交界处的边值，最后问题变成了一个分段两点边值问题。

在多目标优化算法中，算法的好坏需要通过多种指标来恒定，HV指标是一个综合评价指标，且不需要真实帕累托前沿即可对多种算法进行对比，HV值越大则算法效果越好
