FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering and can be used for creation of single-rotor helicopter circuit without tail rotor. Single-rotor helicopter comprises fuselage, rotor, power plant with motors and main reduction gear. Rotor shaft is inclined relative to vertical. Power plant units are arranged on a rotary platform. Rotary platform is mounted on ceiling panel of fuselage to turn about its vertical axis and is equipped with drive, which comprises a motor and a self-braking reduction gear. Axis of rotation of rotary platform is shifted relative to centre of mass of helicopter. Length and angle of inclination relative to vertical of rotor shaft and displacement of axis of rotation of rotary platform relative to centre of mass are selected to ensure compensation of reactive moment of rotor on fuselage. Angle of rotation of rotary platform depends on flight conditions.
EFFECT: reduced power consumption of main engines on compensation of reactive moment of rotor.
