Using Computational Fluid Dynamics (CFD) technology to NACA0018, NACA63A010, NACA4412, NACA23012 simulation analysis is made on four kinds of typical airfoils. It was concluded of the single blade airfoil pressure field, velocity field, lift coefficient and drag coefficient variation, and the simulation curve obtained by the process of analysis. Four kinds of airfoil aerodynamic characteristics factor were integrated under different wind speed conditions. Four airfoils with the best aerodynamic performance in the NACA0018 were adopted as the section airfoils of the wind turbine blades. The MATLAB and SolidWorks software are used to complete the modeling of the wind turbine blades.
