摘要

摘要: 光滑连续变弯度机翼前缘具有降低噪声和提升气动效率的优势.该文在二维翼型柔性蒙皮设计方法的基础上，提出了一种面向后掠机翼变弯度前缘柔性蒙皮的设计方法，其主要改进在于沿翼展方向对多个翼型进行同步优化、对目标函数进行修正从而解决了畸形变形问题，对现有带精英策略非支配排序遗传算法(NSGA-Ⅱ)进行修改以适应三维蒙皮的多目标优化求解.研究表明，与现有设计方法相比，该方法可使柔性蒙皮的变形精度提高27%，实现其在下垂状态下的高精度外形.

Abstract: The smooth continuous wing leading edge with variable cambers has the advantages of reduced noise and improved aerodynamic efficiency. Based on the 2D airfoil flexible skin design method, a design method for flexible skin on the variable-curvature leading edge of a swept-back airfoil was proposed. The main improvement lies in the synchronous optimization of multiple airfoil profiles along the wingspan direction, the modification of the objective function to solve the deformation problem, and the modification of NSGA-II with the elite strategy to adapt to the multi-objective optimization of 3D skin. The research shows that, compared with the existing design method, this method can improve the deformation accuracy of the flexible skin by 27% and realize the accurate shape of the flexible skin in the drooping state.
