blown-boundary-layer control
Flow pattern without boundary layer control.
blown-boundary-layer control
Flow pattern after high-velocity air is blown over the airfoil.
A system in which the blown boundary layer uses high-velocity air blown through ducts or jets to energize the boundary layer on the upper surface of the wing at low speeds, especially during approach and landing to keep the boundary layer from detaching from the wing surface.
