Abstract:

This paper reconstructs the wing and spanwise airfoils of owl using a threedimensional scanner. Referring to the flying characteristic of owl, the aerodynamic of spanwise airfoils are simulated at different angels of attack (AOA) and different Reynolds numbers. Calculation results show that the ratio of lift coefficient to drag coefficient is the largest when the AOA ranges from  3°to 7°,and the best aerodynamic performance airfoil on the whole at spanwise fraction from 40% to 50%.

Key words: engineering bionics, owl airfoil, aerodynamic performance, spanwise fraction
