FIELD: aviation.;SUBSTANCE: invention relates to the field of aircraft engineering and can be used in the design of unmanned aerial vehicles. Unmanned stealth aircraft-helicopter (USAH) is equipped on ends of left and right rotary profiled brackets (RPB) with single-blade rotors, used in vertical and short takeoff / landing or on transient and patrolling modes of flight. After turning in the horizontal plane RPB allow placing the corresponding rotors in side external niches from corresponding boards of inter-wing nacelles. USAH is equipped with two lifting-and-moving turbojet two-circuit engines (TTCE) with controlled thrust vector and power take-off to rotors drive to create lifting force and control moments when vertical takeoff and landing and hovering, and jet thrust at horizontal flight. USAH has mid-centered wing with X-shaped sweep in plan, root parts of which with outruns are mounted above underwing side air intakes of TTCE, having structure from channels with double S-shape at sight and from above, and sideways.;EFFECT: reduced infrared and visual visibility, higher speed and range of flight.;3 cl, 1 tbl, 4 dwg
