It includes a number of wave-shaped vortex generators arranged on the blade suction surface of the blade leading edge side; the wave-shaped vortex generators include a right-angled triangle substrate, the horizontal straight side of the substrate is connected with the blade suction surface, and a number of wave-shaped vortex generators are arranged on the hypotenuse of the substrate Bow-shaped fins, the arc length of several bow-shaped fins decreases along the vertical side to the horizontal straight side, and all the bow-shaped fins are tangent to the same tangent; the lowermost end of the hypotenuse is the area without bow-shaped fins; wave-shaped vortex generator Arranged symmetrically in pairs, the bow-shaped fins face the direction of incoming flow, the two wave-shaped vortex generators deflect at the same angle and the front ends move closer to the axis of the symmetry plane. This structure can more fully stir the airflow in the separator, increase the momentum and energy of the airflow near the wall, and generally more effectively delay the stall of the blade and increase the lift of the blade.
