Device for reducing squall loads on aircraft wings

摘要

In an aircraft having airfoil wings 10 provided with flaps or passages, there are provided, over the outer portion 10c of the wing 10, slot-like narrow flow channels 11 from the underside to the upper side of the wing structure 10, so arranged and designed that the gust lift is nullified, such channels being controlled by respective flaps 12. The flaps 12 may be opened by a gust- sensing system, or by the pressure differential between the lower and upper sides of the wing exceeding a predetermined value. Upward airflow through the channels 11 causes upper surface flow separation aft of the channels, with consequent reduction of lift.
