ROTOR-CRAFT Russian patent published in 2018 - IPC B64C27/22 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly to rotorcraft. Rotorcraft contains fuselage, hybrid powerplant with controlled thrust vectors, concentrically located relative to the fuselage closed wing, with the fuel placed therein, fin, rotaplane main rotor, tail rotor, landing gear. Fin is equipped with controlled gas-dynamic and mechanical rudders. Tail rotors have retractable folding blades. Landing gear main wheels are retracted into the aerodynamic fairings. Main landing gear legs lower supports are located in the half-wings behind the wing in the center wing lower part, are the continuation of wing with enlarged bearing surface with aerodynamic opening fairings-endings on the half-wings for the main landing gear wheels retraction therein. Located above the wing fairing upper part performs the wing fences function, and located under the wing lower part is flaps for the landing gear retraction function.

EFFECT: enabling increase in the flight speed and range.
