HELICOPTER PROPELLER SKEWING AUTOMATIC Russian patent published in 2021 - IPC B64C27/54 B64C27/605 

FIELD: aeronautical engineering.

SUBSTANCE: invention relates to the field of aeronautical engineering, in particular to the design of the swashplate of the main rotor of a helicopter (hereinafter referred to as HMR). The swash plate HMR contains a plate mounted on the HMR shaft, including an outer part equipped with means for adjusting the angle of inclination of the plate, and an inner part containing a spherical bearing having an outer cage configured to change the angle of inclination of the plate, equipped with means for adjusting the pitch of the blades HMR, and an inner a holder mounted on the HMR shaft with the ability to move along it.
