FIELD: transport.
SUBSTANCE: invention relates to production of helicopters. High-speed helicopter comprises airframe, rotor, additional engine, tail rotor, and wings. Extra blade is arranged under every rotor glade, in L-like manner, between rotor shaft and bottom of every blade. Reversible shaft of additional engine is connected with case engaged, in its turn, with helicopter tail frame by manipulator composed of pneumatic cylinder. Second suck pneumatic cylinder displaces tail rotor shaft in case cutout. Both said cylinders allow tail turn in horizontal and vertical planes through more than 180 degrees. Rotary wings prevent helicopter spin in landing with tail rotor failure.
EFFECT: higher speed, reliability and maneuverability.
