n the basis of singular point method. this paper introduces numerical technique boundary element. solving for aerodynamic inverse problem of the blade contour of wind turbine. The linear boundary element discretization improves the accuracy of blade contour inverse problem ramarkablely. Calculating results of the example indicate that boundary element method is an effective way to solve the aerodynamic inverse problem of the blade contour of wind turbine.
