AIRFOIL CONTROL MECHANISM Russian patent published in 2022 - IPC F42B10/62 

FIELD: aircraft.

SUBSTANCE: invention relates to the field of aircraft, namely to control devices for aerodynamic surfaces. The mechanism for controlling aerodynamic surfaces contains bearings, an electric motor, a gearbox, a crank, a slider or a roller, as well as a feedback sensor. In this case, to drive the aerodynamic surface, a flat crank-rocker mechanism is used, in which the link is directly aligned with the aerodynamic surface, on the end surface of which a groove for the slider or roller is made, or it is made separately and fixed on the shaft of the aerodynamic surface. Wherein the crank is installed on the output shaft of the drive gearbox, and the feedback sensor is installed on the shaft of the aerodynamic surface or on the crank shaft.

EFFECT: invention allows to significantly reduce the dimensions and weight of the drive gearbox, unload the drive parts from the perception of aerodynamic forces, optimize the torque-speed characteristic of the drive, install the feedback sensor directly on the airfoil shaft.
