Scientists at Novgorod State University in Russia have invented a unique device for charging drones in various weather conditions while they are in flight, without any contact, allowing them to continue with their mission. According to university experts, the initial goal of this innovation was to address the issue of the limited autonomy of quadcopters, which require frequent recharging or battery replacement. However, researchers later discovered that such a device could be used for other types of drones as well.
The innovators note that using this device does not require any modifications to the drone's structure, as it can be easily attached to its underside. When needed, it ensures efficient power transfer without physical contact with the structure. According to engineer Vitaly Zubov, the device's inventor, the idea for creating this device stemmed from the need to charge quadcopters, but it was found that other drones can also receive electrical current in flight without human intervention.
He mentions that the charging station is equipped with a transmitting coil connected to a power source, which is tuned to a specific resonant frequency. When using alternating current, an alternating magnetic field is generated around the coil, which induces an alternating current in a receiving coil mounted on the drone. If the receiving coil is within range of this magnetic field and is tuned to the same resonant frequency, it will receive the current.
