摘要

The helicopter comprises a main rotor (2) arranged on a cabin (1), on which a rear rotor (4) is fixed over a rear bracket (3) at a distance from the cabin for torque balancing. The rear bracket is provided with units for aerodynamic support for torque balancing. The devices for aerodynamic support for the torque balancing comprise a high-lift flap (5a,5b) on the side turned away from the main rotor rotating direction extending along the rear bracket for accelerating the flow of the discharged air passing through the area of main rotor.
