FIELD: transport.;SUBSTANCE: invention relates to rotorcraft, namely, to VTOL helicopters. Helicopter comprises fuselage, rotors with hubs whereto blades are attached, rotor control system consisting of pilot control stick and control cables connected to rotor blades, autopilot and rotor drive engines. Additionally, helicopter incorporates at least two engine-driven rotors arranged in symmetry about fuselage lengthwise axis to vary common pitch both together and separately. Helicopter control system incorporates rotor rpm control device. Blades are rigidly attached to rotor hubs. Autopilot can stabilise fuselage horizontal position.;EFFECT: improved aerodynamics, higher maximum speed.;3 dwg
