The main purpose of this paper is to demonstrate a bionic design for the airfoil of wind turbines inspired by the morphology of\nLong-eared Owl�s wings. Glauert Model was adopted to design the standard blade and the bionic blade, respectively. Numerical\nanalysis method was utilized to study the aerodynamic characteristics of the airfoils as well as the blades. Results show that the\nbionic airfoil inspired by the airfoil at the 50% aspect ratio of the Long-eared Owl�s wing gives rise to a superior lift coefficient and\nstalling performance and thus can be beneficial to improving the performance of the wind turbine blade. Also, the efficiency of the\nbionic blade in wind turbine blades tests increases by 12% or above (up to 44%) compared to that of the standard blade.The reason\nlies in the bigger pressure difference between the upper and lower surface which can provide stronger lift.
