TRIMMER Russian patent published in 2012 - IPC B64C13/00

Abstract RU 2457981 C1

FIELD: transport.

SUBSTANCE: invention relates to aircraft control and serves to relief pilot control rod forces in manual control and to displace control guide in automatic control. Proposed device comprises power amplifier, contactless torque motor, motor shaft position transducer, reduction gear and electromagnetic brake coupling. Trimmer output shaft rpm control signal is fed top power amplifier first input. Power amplifier second input is connected to motor shaft position transducer output while power amplifier output is connected to motor control windings. Motor shaft is rigidly articulated with electromagnetic brake coupling and, via reduction gear, with trimmer output shaft. Single instruction is fed to brake coupling winding for its disengagement.

EFFECT: simplified design, reduced weight and dimensions.
