Abstract

In the light of the nonlinear distribution of optimal designed attack angle and lift coefficient along blade axis of megawatt wind turbine blade,conventional Willson algorithm is amended.Aerodynamic shape of blade is optimization design by amended algorithm.Based on geometric parameters of blades,the article using point coordinate transformation theory to calculate the actual coordinates of the blade airfoil cross-sections,and then establishing the three-dimensional model of blade by using CATIA modeling software.
