AIRCRAFT SYSTEM INCREASING WING LIFT Russian patent published in 2012 - IPC B64C9/16 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. In compliance with one version, aircraft system increasing wing lift comprises lift increasing flap 2 arranged on aircraft wing to turn about rotational points 3 on wing 1, or on carriage, or lever coupled with wing. Flap 2 may be driven between retracted position 1 wherein it supplements wing shape and several extended positions (II, III) wherein slot 4 is formed between wing 1 and flap 2. Flap 2 is arranged at an angle to wing profile. Rotational point 3 about which flap 2 may turn is located at variable position relative to wing 1, or carriage, or lever coupled with wing. In compliance with another version, hinged is arranged in kinematic element to make additional coupling between flap 2 and carriage, lever first or second end. Kinematic element may displace actuated by drive to vary position of one of hinges.

EFFECT: higher lift.
