Scientists from the Saratov State Technical University have developed a UAV wireless charging system, which includes an input transmitting and receiving electromagnetic coils, figuratively speaking, connected to a power source in the form of a power line and transmitting it to the drone receiver coil itself.
As specified, when collecting one of the wires of the power line as a transmitter coil, a sufficiently developed area is created, the needs of which the drones that consume the receiving coil consume to load their batteries without the need for a direct connection to the mains.
At the same time, “aircraft” UAVs can be recharged by the span load of high-voltage power lines at a distance of 1-2 meters, and “helicopter” class drones will be charged by the battery charge, landing on the lines (wires) of the power transmission line.
The key feature of this system was the use in the cation of a separate, coarse, increased magnetic permeability material – this is an elastic ferromagnet, and the front side of the perception will be made of a special metamaterial (polymer with a thin wire), which acts as a kind of lens for focusing electromagnetic waves.
Nevertheless, this development of the Saratov socialists is theoretical today, and there is no information about the possible timing of the production of a working system. is given.
