UNMANNED JET-HELICOPTER Russian patent published in 2019 - IPC B64C27/22 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of converted rotary-wing aircrafts. Unmanned reactive aircraft-helicopter (URAH) has engines of power plant (PP) transmitting torque through main reduction gear and connecting shafts to bearing screws, tail unit and three-support retractable wheel chassis. URAH is equipped with two gas turbine engines (GTE) mounted side by side on both sides of the axis of symmetry in the above-air nacelles in pairs in front or behind the pylon, or abutting in the side fuselage nacelles, forwarded from the pylon of twin-screw BS (TBS) above the vortex-forming, integrated with the cantilevers wing with extensions, front of which have an angle of greater sweep and attack compared to the wing, form a V-shaped configuration when viewed from above. URAH has two coaxial TBS and two remote coaxial blowers (RCB) in a annular fairing arranged in the aft fuselage compartment, which directs the compressed air flow to the side rotary nozzles (SRN), creating a lift at vertical and short take-off/landing (VTL and STL) together with coaxial TBS or cruise thrust.

EFFECT: higher speed and range of flight, easier control on pitch and roll when performing VTL and hovering.
