HELICOPTER HEADING POSITION CONTROL DEVICE WITH COAXIAL PROPELLERS Russian patent published in 2021 - IPC B64C27/10 B64D35/06 

FIELD: aviation technology.

SUBSTANCE: invention relates to the field of aviation technology, namely to control systems for helicopters with coaxial propellers. A helicopter heading position control device containing a system of coaxial rotors mounted with the ability to rotate in opposite directions on the rotor and stator of the traction motor, the power source includes an adjusting motor, the stator of which is connected to additionally inserted resistor. The shaft of the lower rotor is connected to the shaft of the regulating electric motor, fixed on the helicopter body with the possibility of transmitting to the helicopter body of the torque, the direction of which is opposite to the direction of rotation of the lower rotor when power is supplied to the regulating electric motor, and the possibility of transmitting the torque to the helicopter body, the direction of which coincides with the rotation of the lower rotor when the control motor is closed to the resistor.

EFFECT: simplification of the design of the controls along the course of the helicopter, made according to the coaxial scheme, is provided.
