DEVICE FOR DELAYING BOUNDARY LAYER SEPARATION

摘要

The invention relates to a device for delaying the separation of a boundary layer in a flow of air (10) on a wall (12), including holes (14) formed in the wall (12) and connected to compressed air supply valves (18) by means of channels (16), the frequency of the valve opening and closing cycles and the valve opening duration being selected so as to generate peak output velocities from the holes (14), which occur in quasi-continuous succession. The invention is particularly suitable for aircraft wings and motor vehicle bodies.
