POWER MINIDRIVE OF MOVABLE AEROFOIL OF AIRCRAFT Russian patent published in 2010 - IPC H02K7/116 B64D31/14 

FIELD: electricity.

SUBSTANCE: power minidrive comprises casing (1), inside of which there is an open-frame electric motor arranged coaxially along longitudinal axis, comprising stator (2) and rotor (3) fixed on shaft (4). There is a wave gear with solids of revolution, either single-stage, where only output stage (18) is used, or multi-stage, where output stage (18) is used, as well as intermediate stage (10). Position sensor consists of stator (28) and rotor (29) installed on output link (19) of wave gear. On end surface of output link (19) of single- or multi-stage wave gear with solids of revolution there is a bushing (25) fixed eccentrically to longitudinal axis with traction rod (35). Traction rod (35) has eyes at the ends, one of which is placed onto bushing (25) with the possibility of rotation around axis of bush, and the second one is intended for fixation to fixed part (32) of aircraft. Body (1) is equipped with element (34) of fixation to movable aerofoil (31) so that longitudinal axis is aligned parallel to axis of rotation (33) of movable aerofoil (31) of aircraft.

EFFECT: provision of control of movable aerofoil, axis of rotation of which is arranged outside volume of movable aerofoil and increased reliability of control by redundancy of power minidrives according to principle of forces summation.
