[0002] The cloud catalyst spreading pod is a device for artificial weather modification. The device is used for artificial rainfall, artificial cloud removal, artificial fog removal and other operations in drought areas, forest fire areas or other key areas to reduce or eliminate disaster losses.

[0003] Currently, artificial rainmaking and cloud dispersal mostly use the method of spreading catalysts or explosions. The catalysts are mainly spread by aircraft or rockets. Fog is generated near the ground, and fog dispersal is dangerous and difficult. Currently, only a few airports use fog dispersal, and there is a lack of technical means for artificial fog dispersal.

[0004] At present, China has a patent for a hygroscopic aerial dry powder spreading device, patent number: CN201721615080.7, which is a dry powder spraying device installed on a manned aircraft, and its airborne and spraying structure design. At present, there is no research and report on the use of drone mounting and the use of manned aircraft external mounting spreading equipment and control. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, provide a pod for spreading cloud catalysts and a control method thereof, and provide a device and a control method for spreading artificial rainmaking, artificial cloud elimination, and artificial fog elimination catalysts that can be mounted on an unmanned aerial vehicle and can also be mounted outside the cabin of a manned aircraft.
