FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering and can be used in design of rotorcraft. High-speed jet aircraft-helicopter (HSJAH) comprises two-propeller bearing system at the wing ends, power plant engines (PP) transmitting torque through the main reduction gear and connecting shafts to the bearing rotors (BR), tail unit and three-support retractable wheel chassis. In the integrated aerodynamic scheme HSJAH is equipped with two or four combined gas turbine engines (CGTE) installed on both sides from axis of symmetry in underwing/wing-top nacelle integrated in root wing parts. CGTE are made in the form of double-flow engines, having external outline with remote turbo-blower (RTB) and internal circuit with free turbine, equipped with front shaft output for power take-off via clutches to input shafts of T-like in plan of intermediate reduction gears, redistributing take-off power of PP between two two-bladed BR (TBBR) and two coaxial or single-row RTB.
EFFECT: higher speed and range of flight, easier control of pitch and course when performing VTOL and freezing.
