The positions of the first sensor  5  and the second sensor  6  are the closest, so the signal from the second sensor  6  can be received in time and feedback to the ground monitoring room. It is convenient for the staff in the ground monitoring room to send the detonation control signal to the cannonball for artificial precipitation  2  and achieve precise delivery and detonation 
     Moreover, the soft lock  4  is provided with multiple. The two ends of multiple soft lock  4  are respectively connected to the interval position on the unmanned aerial vehicle  1  and the interval position on the cannonball for artificial precipitation  2 .

For one cannonball for artificial precipitation  2 , more than two soft locks  4  can also be used to connect it, so as to ensure the release attitude of the cannonball for artificial precipitation  2  and ensure the detonating effect. In some embodiment, the attitude and stability of the cannonball for artificial precipitation  2  can be adjusted to improve the delivery accuracy by adjusting the length of multiple soft locks  4  and cooperating with the wing surface  7  on the cylinder  3 , 
     Moreover, the second sensor  6  is provided with multiple. Multiple second sensors  6  are spaced on the cannonball for artificial precipitation  2 . 
     In this embodiment, considering the release attitude of the cannonball for artificial precipitation  2 , it can be positioned by multiple second sensors  6  for attitude adjustment. More than two second sensors  6  can be used as a backup. If one of the second sensors  6  fails, it can ensure that there are other second sensors  6  to send position signals to the ground monitoring room or controller. 
     Furthermore, the unmanned aerial vehicle  1  is vertical takeoff and landing unmanned aerial vehicle. 
     Furthermore, the fixed wing vertical takeoff and landing unmanned aerial vehicle is selected as the large load capacity and long endurance time, less energy consumption.
