FIELD: aviation.
SUBSTANCE: invention relates to designs of main rotors of light helicopters. The invention is aimed at creating a main rotor hub with an elastic, maintenance-free fastening of the main rotor blades, with a minimum number of parts. The main rotor sleeve consists of a prefabricated hub, Y-shaped plate elastic elements, pins, streamlined casings, traverses with support spherical hinges on one side and adapters that compress the elastic element package and serve to fasten the blade, on the other side. The overhang limiter comprises a sliding ring with holes for interaction with carriers, guide brackets of the overhang limiter ring, and carriers. The drive pieces that control the installation angle of the blades are located in the rear part of the streamlined casings.
EFFECT: reduced terms of pre-flight and post-flight inspections and maintenance of a helicopter.
