ASSEMBLY OF ATTACHING THE BUSHING AND HUBS OF THE CARRIER PROPELLER TO THE PYLON WITH DIRECT CONTROL OF THE TILT OF THE ROTATION AXIS FOR CONTROL OF THE CAR Russian patent published in 2021 - IPC B64C27/52 B64C27/02 

FIELD: aeronautical engineering.

SUBSTANCE: invention relates to aeronautical engineering, in particular to the design of rotors. The unit for attaching the rotor hub and the rotor hub to the gyroplane pylon contains a rotor shaft made with the possibility of rotating the rotor hub around it with the help of the drive. The hub is pivotally connected to the hub with blades attached to it. The rotor shaft is fixed with a hinge assembly on the gyroplane pylon, and the hinge assembly contains a roll control joint and a pitch control joint. The axes of the control joints are perpendicular to the axis of the rotor shaft and to each other. The axis of the hub joint is perpendicular to the rotor shaft axis and is located at a distance from the pitch and roll control joint axes selected from the range from 0 to 50 mm. Control rods are connected to the hub, made with the possibility of turning the rotor shaft axis by an angle of up to 10 degrees in any direction relative to the vertical axis of the pylon.

EFFECT: reduced load on the control stick of the pilot in the plane of rotation of the main rotor, including vibration loads.
