UNMANNED VERTIPLANE WITH CHANNEL PROPELLERS Russian patent published in 2017 - IPC B64C37/00 B64C27/28 

FIELD: aviation.

SUBSTANCE: unmanned vertiplane with channel propellers is made in the aerodynamic scheme "duck" with a short fuselage having a drop-shaped, streamlined form. The centerwing has two annular cutouts that provide inside the latter a deflection of rotary annules ducts (RAD) with propeller reduction gears whose centers are located along the Z-Z axis so that the left and right RADs are equidistant from the center of mass and do not extend beyond the rear edge of the wing centerwing. Each RAD has a pair of smaller double-bladed propellers with opposite rotation, placed under the central large propeller on a vertical shaft in a cowling mounted in the body of RAD central body on its profiled beadings. The vertiplane is equipped with the ability to convert its flight configuration from a helicopter of a six-propeller carrier scheme with the vertical arrangement of their RADs in the flight configuration of a double-propeller aircraft having two pairs of smaller crossing screws that are disconnected from the transmission.

EFFECT: increasing the payload, reducting the required power for longitudinal balancing in case of hovering.
