FIELD: transport.
SUBSTANCE: invention relates to hydroaviation. Proposed helicopter comprises airframe 1 with tail boom 11, gas turbine engine 8 with two coaxial rotors 9, delta wing with leading edge flap 13 whereon rests semi-cylinder airframe 1 and below which three floats 2, 4 are arranged equipped with retractable damping sliding hydroski, twin-fin tail with fins 6 resting on side float rear part 4 and top part connected via stabiliser 12 with airframe rail boom, two horizontal thrust propulsors with pusher propellers 7 mounted on tail fins. Said delta wing exploits airflow feed from rotors generates air cushion with leading edge flap 13 and side floats 4.
EFFECT: higher stability, lower impact loads.
