AIRPLANE WING FLAP CONTROL DEVICE Russian patent published in 2022 - IPC B64C9/34 

FIELD: aviation

SUBSTANCE: invention relates to aviation, namely to the designs of the actuators of the airplane wing-flap control systems. The airplane wing-flap control device contains retractable rotary wing-flaps, wing-flap drives, bearing units made in the form of rectilinear rails rigidly connected to the wing, carriages, hingedly connected to the flaps and movably mounted on the bearing rectilinear rails, fairings and a wing-flap extension mechanism. In addition, the wing-flap control device is equipped with curved guide rails rigidly connected to the wing and interacting with rollers fixed on the leading edge of the wing-flaps, and the wing-flap extension mechanism is made in the form of a system that includes a bearing straight and curved guide rails rigidly connected to each other and to airplane wing, installed in the space between two wing-flaps connected by a hitch located at the rear part of the wing-flaps.

EFFECT: proposed device makes it possible to improve the aerodynamic characteristics of the wing in take-off and landing modes by ensuring the optimal trajectory of the wing-flap movement with a large wing-flap rollout.
