The invention discloses a transonic speed buffeting control structure based on wing trailing edge vent holes, and belongs to the technical field of aircraft flow control. The buffeting control structure is a vent hole formed in the rear edge of the wing, one end of the vent hole is communicated with the upper surface of the wing profile, and the other end of the vent hole is communicated with the blunt rear edge of the wing profile; the aperture of the vent hole and the thickness of the wing-shaped trailing edge are in the same magnitude. According to the method, buffeting can be controlled, and meanwhile the influence on the lift-drag characteristic of the original wing is reduced.

    本发明公开了一种基于机翼后缘通气孔的跨声速抖振控制结构,属于飞行器流动控制技术领域。抖振控制结构为设置在机翼后缘内部的通气孔,通气孔的一端与翼型上表面相通,另一端与翼型钝后缘相通;通气孔的孔径与翼型后缘厚度为同一量级。本发明能够在控制抖振的同时,减少对原机翼升阻特性的影响。
