UNMANNED AERIAL VEHICLE FOR VTOL Russian patent published in 2023 - IPC B64U10/20 B64C29/00 

FIELD: aviation.

SUBSTANCE: designs of unmanned aerial vehicles. An unmanned aerial vehicle for vertical takeoff and landing contains a fuselage (1), wings (2) located in the middle part of the fuselage on the sides, a fin (3) located in the rear part of the fuselage (1), an internal combustion engine (8) with a drive shaft (9), located in the rear fuselage. The drive shaft (9) is connected to the fans (14) through the main gearbox (10), clutch (11), continuously variable transmission device (12), gearboxes (13), and to the propeller (15) through the main gearbox (10), clutch (11). Fans (14) are installed in the middle part of fuselage (1) in such a way that they are able to create a fluid flow from the hole in the upper part of the fuselage in the direction from the fuselage to the sides. Lifting wings (19) are installed on brackets (16), in niches (6) on the sides in the middle part of the fuselage (1), and are designed in such a way that in the STOL position, the lifting force is created by a fluid flow in the direction from the fuselage to the sides. The motors (18) are configured to rotate the lifting wings (19) relative to the axis (17) of the brackets (16).

EFFECT: increase in load-carrying capacity, efficiency and increase in the duration of the flight of the unmanned aerial vehicle.
