介绍了在满足高超音速再入横向机动航程，高超音速再入飞行时的升阻比，亚音速进场飞行时的升阻比，纵向静稳定性裕度和水平着陆速度等飞行性能设计要求下，用罚函数法寻求使航天飞机机翼质量为最小的外形优化方法并给出了算例．计算结果表明，方法对初步设计阶段中航天飞机机翼外形的选择，有参考价值 The requirements of flight performance such as lift-drag ratio at hypersonic reentry transversal maneuver range, hypersonic reentry flight, lift-drag ratio at subsonic landing flight, longitudinal static stability margin and horizontal landing speed are introduced , The method of penalty function is used to seek the shape optimization method that minimizes the spacecraft wing mass and gives an example. The calculation results show that the method has some reference value for the choice of spacecraft wing shape in the preliminary design stage
