HIGH-SPEED HYBRID ROTORCRAFT Russian patent published in 2018 - IPC B64C27/22 B64C27/24 B64C39/08 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engineering, in particular to the designs of rotorcrafts. High-speed hybrid rotorcraft (HSHR) has at the ends of the wing brackets the bearing screws with gears, power unit engines (PUE) connected by connecting shafts, propeller and propellers, fuselage and tail fins rotate. HSHR is equipped between high-lying closed wings (HLCW) with single-blade large rotor screws (RS) with shaped counterweights, providing the creation of vertical traction only for vertical and short takeoff / landing (VTL and STL), and smaller screws mounted between the U-shaped tail fins on its interkeeled profiled T-shaped front view of the pylon. HSHR is configured to convert the flight configuration from a rotorcraft or a helicopter after performing a VTL or STL to a high-speed rotorcraft or aircraft with marching smaller screws with large RSs operating at regimes close to their autorotation, or with fixed wing blades of left and right large RS.

EFFECT: provides an increase in payload and weight return, increasing the speed and range of flight, simplifying longitudinal balancing.
