The aerodynamic performance of barn swallow airfoil was analyzed through numerical simulation. Imitating barn swallow airfoils, 100 W horizontal axis wind turbine blade was improved. Aerodynamic performance of bionic blade was analyzed. The test platform of small-sized horizontal axis wind turbine was set up, the efficiency contrast tests between the bionic and the standard wind turbine were done. The results show that the aerodynamic performance of barn swallow airfoil is fine. The maximum lift coefficient and the maximum lift-drag ratio of barn swallow airfoil is 1.78 times and 1.77 times of standard airfoil, respectively. The output power of bionic blade is higher than standard blade. The average improve rate is 26.48%.
