METHOD AND DEVICE TO AUTOMATICALLY DECREASE LOAD ON HIGH LIFT GENERATING CONTROL SURFACES, PARTICULARLY, ON AIRCRAFT LANDING FLAPS Russian patent published in 2011 - IPC B64C13/24 

Abstract RU 2415776 C2

FIELD: transport.

SUBSTANCE: invention relates to aerodynamics. Proposed method consists in automatic reduction of load on control surfaces generating higher lift in case sticking originates. Proposed device has, at least, one surface generating high lift driven by local mechanical final control element in response to control signal generated by control device is set to predefined position by central drive coupled via rotary shaft with said local mechanical final control element to transmit torque generated by central drive to rotary shaft. If signal designating origination of sticking in control surfaces, then torque transmitted to rotary shaft by central drive is automatically reduced to preset lower level to fix the position of control surfaces generating higher lift.

EFFECT: automatic reduction of load.
