UNMANNED AERIAL VEHICLE Russian patent published in 2023 - IPC B64C27/08 B64C39/02 B64U10/10 B60L53/20 

FIELD: UAVs.

SUBSTANCE: unmanned aerial vehicle comprises a central platform, electric motors with propellers fixed in a certain way. The central platform comprises two sealed compartments in the form of upper and lower hemispheres, separated by a bulkhead made in the form of a curved surface of a spherical segment made of ferromagnetic material. A distributed electric winding is rigidly fixed on the inner surface of the bulkhead, the leads of which are connected to the battery. The upper hemisphere comprises a pin movably fixed to its top by means of a spherical hinge. A plate-shaped permanent magnet is attached to the other end of the rod. The lower hemisphere comprises a battery, a route computer system, a video surveillance system, a GPS navigation receiver located on the inner side of its lower surface. A float is fixed to the outer surface of the base of the lower hemisphere with the help of shock absorbers and rods. An arc is attached to the float, enveloping both hemispheres and having a connection with a pin through a hole in the top of the upper hemisphere and a lip seal. On the lower surface of the float, a water surface touch sensor is rigidly fixed, connected to the route computing system.

EFFECT: increased flight duration by charging the battery with the help of the wave energy of the water surface.
