Design And Three Dimensional Modeling On Wind Turbine Blades

The paper studied the design model, three dimensions modeling of the blade of the horizontal axis wind turbine. The main conclusions are as follows:1 Blade optimum design. Give an example of 750kW the horizontal axis wind turbine to research in the optimum design. The calculation procedure of a rotor blade has been worked out according to Wilson method in this subject. This subject has adopted MATLAB language as computer program language.2 The precise 3D blade. Blade was designed with the aerofoil NACA4412, based on the above blade parameters, the data of the aerofoil of blades were revolved and converted to the data of the 3D-block body of blades, The 3D model was drawn with Unigparhics NX3 based on the 3D theory.
