摘　　要：Gurney襟翼是指在翼型后缘的下表面垂直弦线、高度很小、厚度也很小的片状增升装置。在一定的条件下 ,Gurney襟翼可以明显增大翼型的升力系数和升阻比。实验表明 ,Gurney襟翼应用于小雷诺数的风扇叶片时 ,可明显提高风扇叶片产生的推力 ,从而提高风扇的风量。Gurney flap is a high_lift device, which is a small flat plate flap attached to the pressure side of the airfoil near the trailling edge and perpendicular to chordline of the airfoil. Under some conditions, Gurney flap can increases lift coefficient and lift_drag ratio of the airfoil. Experiments proved that Gurney flap can increases flux of fan working at lower Reynolds numbers.
