CONVERTIBLE DRONE ROTORCRAFT Russian patent published in 2011 - IPC B64C37/00 B64C27/22 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering and my be used in designs of light convertiplanes and drone rotorcraft. Proposed machine comprises fuselage, engine, tail unit and three-leg fixed landing gear, and represents aerodynamic tandem configuration with variable-sweep wings. It incorporates low front and high rear wings that may deflect back and forth through direct and back swept angles and be moved into relevant wells in conversion into helicopter, and V-like tail unit. Transverse rocking arm is articulated atop fuselage to support lengthwise rocking arm wherein engine nacelle is made while main reduction gearbox is arranged in cone. Central reduction gear is coupled with main reduction gearbox output shaft with angular reduction gearboxes with rotors. Swinging of said rocking arms allows controlling convertible drone rotorcraft flight.

EFFECT: simplified transmission, better controllability and expanded flying performances.
