Abstract
In order to better understand the influence of camber on aerodynamic performance of airfoil, airfoil NACA0012, NACA2412, NACA4412 and NACA6412 were selected as research objects to conduct numerical simulation at 10m/s. According to lift coefficient, lift-drag ratio and airfoil pressure cloud diagram, the influence of camber on airfoil aerodynamic performance is obtained. The results show that the lift coefficient of airfoil increases with the increase of airfoil bending degree within a certain range of attack Angle. The lift-drag ratio of airfoil increases with the increase of its bending degree.
