Abstract

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.
