乘子罚函数法在航天飞机机翼外形优化设计中的应用

APPLICATION OF THE MULTIPLIER PENALTY FUNCTION METHOD TO THE OPTIMUM DESIGN OF WING CONFIGURATIONS OF AEROSPACE VEHICLE

本文采用乘子罚函数法,在满足高超声速配平和低亚声速进场着陆的要求以及几何约束条件下,寻求在不同重心位置时使航天飞机机翼质量极小的气动外形。计算结果表明,航天飞机机翼外形优化设计具有重要意义。

In this paper, the multiplier penalty function method is utilized to seek the aerodynamic configurations of wing which maintains the minimum mass in different center-of-gravity positions, when the requirements of hypersonic trim and low subsonic landing as well as the geometric constraint condition are satisfied. The computational results show that there is an important significance in the optimum design of wing configurations of aerospace vehicle.
