Referring to fig. 1, the charged particle generator array is loaded in a streamline airborne suspension cabin, two direct current high voltage supplies with opposite polarities outputting 30kV through a high voltage feeder line are used for supplying power, and when the device is in operation, the two high voltage supplies simultaneously output currents with opposite directions, and through balancing control on the output currents of the two power supplies, the whole set of charged particle catalytic rainfall equipment can be ensured to keep electrically neutral, and the requirements of equipment operation and unmanned aerial vehicle flight safety are met. In the process of flying the unmanned aerial vehicle at high altitude, the charged particles generated by the charged particle generator are blown out by air flow through the air inlet of the streamline airborne pod, so that artificial catalytic precipitation is realized.
Referring to fig. 2, the body of the charged particle generator is composed of a needle electrode and a ring electrode.
