FIELD: transport.
SUBSTANCE: invention relates to production of helicopters. Single-seat helicopter comprises tubular airframe with power plant arranged at its bottom part and furnished with assembly units and mechanisms required for transmission and distribution of torque via shafts to coaxial opposite-rotation rotors mounted at helicopter top part. Pilot cab is arranged above said rotors, jointed with said airframe and equipped with necessary controls. Helicopter vertical sizes are one and a half time larger than rotors while helicopter center of gravity shifted downward does not exceed one third of said vertical size at full load of helicopter.
EFFECT: higher safety, better controllability.
