TRIMMING MECHANISM Russian patent published in 2009 - IPC B64C13/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to control systems of flying vehicles and is intended for creation and removal of efforts from the pilot control handle in manual flight control, as well as for remote control in automatic trimming conditions. The proposed mechanism incorporates a motor and reduction gear, output shaft position pickup, amplifier-adder and integrator. The electric motor is linked up, via reduction gear, with the trimming mechanism output shaft and output shaft position pickup the signal from which is sent to the amplifier-adder first input. The second input of the amplifier-adder is connected to the integrator output, the integrator input being connected, via N.O.-contacts of the pilot control handle, with the amplifier-adder output connected, in its turn, with the motor control winding. The amplifier-adder third input is connected to the trimming remote control circuit.

EFFECT: simplified design, reduced weight and dimensions.
