초록

Turbulence in the boundary layer of a flow of air across a surface is controlled by sucking air from the surface. A plurality of turbulence detectors are located in the surface downstream of apertures provided in the surface. The apertures are connected to a suction pump. Air is sucked through the apertures until the air flow of the most downstream of the detectors is non-turbulent.
