翼型厚度对气动性能的影响

Influence of Airfoil Thickness on Aerodynamic Performance

增加翼型厚度在一定程度上可以提高叶片的气动性能,在小攻角下,较小厚度的翼型有较大的升阻比,在大攻角范围时,当原始翼型发生失速时,较大厚度的叶片可以提高翼型的升力系数,还可以扩大翼型的失速范围,可以有效改善翼型的流动特性。

Increasing the thickness of the airfoil can enhance the aerodynamic performance of the blade to a certain extent.At a small angle of attack,the airfoil with a smaller thickness has a larger lift-to-drag ratio.At a range of large angle of attack,when the original airfoil stalls.Larger thickness blades can increase the lift coefficient of the airfoil,and can also expand the stall range of the airfoil,which can effectively boost the flow characteristics of the airfoil.
