SCREW, FOR EXAMPLE HELICOPTER ROTOR Russian patent published in 2021 - IPC B64C27/64 B64C27/605 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly to designs of helicopters main rotors. Helicopter rotor has rotor bushing and rotor blades. Rotor bushing has a housing and axial hinges, its own for each rotor blade. Each rotor blade is configured to individually control the angle of its installation by means of its vane partial-turning hydraulic motor. Each of the non-rotary hydraulic motors is installed on the rotor bushing, is built into the axial hinge of its rotor blade and is made with possibility of interaction with the above housing of the rotor bushing and with its own rotor blade. Rotor hub also accommodates a container with working fluid, slide valves, a hydraulic pump and a filter designed to ensure operation of the above-mentioned incomplete rotatable hydraulic motors.

EFFECT: helicopter rotor design is described.
