MULTI-ROTOR UNMANNED ELECTROCONVERTIBLE AIRCRAFT Russian patent published in 2015 - IPC B64C27/28 B64C39/02 

FIELD: aviation.

SUBSTANCE: multi-rotor unmanned electroconvertible aircraft contains glider made of composite materials with high-mounted wing, in the middle of pivoted arms of which the motors with gearboxes and rotors are mounted in nacelles, creating the horizontal and vertical traction by their corresponding deviation, synchronising the T-system of transmission shafts, connecting two engines inter se and two engines with tail rotors, mounted behind the T-tail at the end of elongated beam, wheel landing gear with nose auxiliary and main supports, deployed in the nose and side compartments. Two three-rotor modules designed with possibility to operate at different angles of their deflection in vertical plane, having different-sized rotors, are installed at the ends of the internal rotary sections of the C-shaped wing, having the positive angle of transverse V. The left and right larger rotors are installed in the hybrid engine nacelle with the front disposition of the power plant, equipped with two smaller rotors at the end of streamlined elongated rear portion, arranged around the larger rotor behind its outer and inner quadrants according to the distributed traction system of different-sized rotors. Electroconvertible aircraft can be made according to tandem scheme and installation of two three-rotor modules on the rear larger wing.

EFFECT: increase of load ratio, transport and fuel efficiency.
