HELICOPTER ANTI-TORQUE ROTOR Russian patent published in 2019 - IPC B64C27/82 B64C27/68 B64C11/44 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to propeller designs. Anti-torque rotor (4, 4') of helicopter (1), comprises supporting body (14, 14'), drive shaft (10, 10'), which rotates about first axis (B), hub (11) connected operatively to drive shaft (10, 10') and angularly fixed with respect to first axis (B). At least one blade (12) is connected operatively to hub (11), is angularly fixed with respect to first axis (B), and is angularly movable with respect to second axis (D) to adjust the pitch angle of blade (12). Actuator (16, 16') which can be operated to adjust the pitch angle of blade (12) and comprises electric motor (25, 25') which generates torque along first axis (B), and mechanical stage (30, 30') interposed between electric motor (25, 25') and blade (12), and designed to convert the torque into rotation of blade (12) about respective second axes (D). Electric motor (25, 25') is fixed to supporting body (14, 14').

EFFECT: providing accuracy of mounting blades for improved control and maneuverability of the helicopter.
