Service Background
During flight, aircraft are subject to various charging factors, including electrostatic charging (several hundred kV can be charged within 1 second), atmospheric electric field induction charging, geomagnetic field induction charging, plasma charging (high-temperature, high-pressure jet engine exhaust negatively charges the aircraft), and strong field irradiation. Since grounding is not possible during flight, the electrostatic voltage of the aircraft can reach 300kV. When the aircraft comes into contact with external objects, it will generate a huge spark discharge (e.g., between the refueling nozzle and the refueling port, between the helicopter hook and the load, between unloading cargo and the ground), which can lead to a reduction or damage to the system performance, or even cause safety accidents.
