UNMANNED AERIAL VEHICLE Russian patent published in 2018 - IPC B64C27/08 B64C39/02 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation equipment, namely, to the unmanned aerial vehicles (UAVs). At the axes ends the UAV contains central platform, which second ends are rigidly fixed thereto and oriented relative to its center, and rigidly fixed, at least eight electric motors with coaxial propellers with controlled speed. Adjacent engines has the opposite direction of rotation, the electric motors are connected to the battery and the route computer system, the flight controller and motor controllers, mobile control and monitoring panel, video surveillance system and GPS navigation receiver. In addition, electric motors with propellers are installed inside the rings, whose aerodynamic profile faces the propellers end parts, which rotate in the ring with the relative gap of 0.45–1.5 % of the ring diameter.

EFFECT: enabling increase in the UAVs carrying capacity with the same consumed power for the flight, as well as increase in the flight duration and range at the same consumed power.
