Abstract: Wnd turbine blade design methods of momentum theory, bladed element theory and the amendatory Glauert theory were described in this paper. The blade models of turbine were founded in the software of bladed, the aerodynamics performance of airfoil and the wind turbine power curves were obtained by the 2.0 MW-D111 wind turbine. The results show that the original design is accord with the calculation results, indicates that the blade airfoil parameters and design method are feasible, which has certain reference value to the design of wind turbine blade.
