COMBINED ROTOR PITCH CONTROL UNIT AND THE HELICOPTER ENGINE WITH THE PAIRED CONTROL SYSTEM AND THE CLUTCH FOR IT Russian patent published in 2018 - IPC B64C13/12 F16D11/08 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to helicopter construction, in particular to the control systems of the main rotor pitch and the helicopter engine. Combined rotor pitch control unit and the helicopter engine with the paired control system comprises a first and a second main rotor pitch control arms provided respectively with the first and second engine speed correction knobs. In the mechanical wiring synchronization of the engine speed adjustment knobs a controlled clutch is integrated, the control input of which is connected to the second main rotor pitch control lever. Controllable clutch includes a controllable half-coupling equipped with a control mechanism and an uncontrolled coupling, which have the possibility of mutual contacting each other geometrically similar to each other end surfaces of inclined sections of their cylindrical bodies, mounted coaxially with the possibility of rotation around its axis.

EFFECT: possibility of connection or disconnection the engine speed control knob to the mechanical wiring of the handles synchronization, self-adjusting parts of the clutch transmitting the torque to a predetermined angular position relative to each other is ensured.
