N2 - In this paper the choosing principles of design parameters and multi-airfoils in horizontal axis wind turbine (HAWT) generator system aerodynamic design are introduced. On the basis of the comparison analysis of wind turbine aerodynamic design method Wilson and Schmitz, a HAWT optimized design method based on Schmitz is presented. In this Schmitz optimized method different aerodynamic losses are considered and 2 real physical parameters are used instead of induced factors of Wilson method. The design results show that HAWT optimized design method based on Schmitz makes good agreement with Wilson method. After chord length distribution is corrected due to practical reasons, a twist angle correction method is also presented based on the principle of maximum wind energy capture. Applying the methods improved in this paper, a 2 MW HAWT for doubly fed induction asynchronous generator (DFIAG) is designed in terms of aerodynamic aspect, taking blade structural strength into account. Applying Schmitz extending method, the partial load characters are calculated. The results show that designed HAWT partial load characters are in agreement with the results of GH Bladed software simulation.
