AIRCRAFT FLAP DRIVE SYSTEM Russian patent published in 2023 - IPC B64C19/00 

FIELD: aircraft control systems.

SUBSTANCE: invention relates can be used in the production of various types of unmanned aircraft, for example, those intended for sensing the marine environment and monitoring the state of vast water areas. The flap control system of the aircraft includes a magnetoelectric drive made in the form of a streamlined body fixed to the blades, equipped with two groups of electric coils installed inside, arranged in parallel, one above the other, the windings of which are connected in series and placed on tubular frames. At the same time, upper and lower hollow rods are passed through the holes of the upper and lower groups of frames, respectively, inside which permanent magnets are installed, separated by non-magnetic bushings. Tips are fixed at the ends of the rods, in which cylindrical pins are installed, which are included in the grooves of the wings, fixed on the flap axis, installed in bearings fixed in the drive housing, and the windings of the electric coils connected in series are connected to the electronic unit, to which the flap angle sensor is connected, which is installed in the streamlined housing of the drive.

EFFECT: increased reliability and reduced weight of the aircraft control system, compensating for the stroke of the rotor blades and the possibility of automatic control without the use of steering gears, as well as the possibility of implementing various algorithms for controlling the rotor blades and reducing aerodynamic drag of the aircraft.
