According to reports, Russia's GET company pioneered the development of an airborne inductive charging system. The system looks very simple: a set of poles on the flexible transmission line, forming a hexagonal diameter of about 10 meters on the ground, a bit Like the frame of a pavilion. In fact, this builds a charging area with a distance of tens of meters, which can wirelessly transmit kilowatts of electricity.
When a drone with the proper configuration and settings flies into this range, up to 12 kW of power can be transmitted to the drone with approximately 80% efficiency. The drone stays in the charging area for 6 minutes (circling or hanging) It is enough to get about 25 minutes of endurance. GET's in-flight charging station gives industrial drones the possibility of flying without time.
The system is simple, portable, can be deployed or moved as needed, or it can be set up along a long-haul line with multiple charging circuits that are several kilometers apart. The drone continuously monitors the area and hovering to the nearest charging area as needed. Charging, when the battery is full, it will fly to the next station. Since the system can charge multiple drones at the same time, it is not a problem to support the drone formation.
GET claims that it strictly controls the electric field or magnetic field density of the charging area, which is lower than the limit approved for general applications, so the system is safe for both humans and animals.
GET called this design 'reinvented' the commercial drone industry, providing a technical solution for powered drones in a specific area of 24×7 mode. It also has potential applications in many other industries, such as mobile communications, robotics. Wireless charging of medical equipment, industrial equipment, pipelines (oil/gas) detectors, warehouse vehicles, electric vehicles and other electronic equipment.
This natural thing, why didn't anyone do it before? GET has its own explanation. They think that their remote wireless power technology is based on resonant coupling circuit, but it has designed a unique engineering solution under the electromagnetic field with completely safe density. Work to provide energy over long distances with optimal analog efficiency. The success of the project also benefits from compressing the cost of high-power semiconductor devices in the selected frequency range to a reasonable range. A key component is the flexible power transmission line used as an energy transmitter. It can be made several kilometers long, simple, safe and easy to deploy. In addition, the combination with other technologies in the complementary industry makes this air charging solution possible.
Let the drone operate in the air for a long time, this is a hot spot in the industry. For example, Bhark, its idea is to explore alternative fuels such as hydrogen to provide long-term flight for drones. GET is focused on the air. Charging. It recently announced and demonstrated its technology at the AUVSI Xponential 2018, the largest annual exhibition in the driverless industry, and was awarded the third place in technological innovation.
