• Birds are the great enemy of aviation safety Birds are the great enemy of aviation safety, and there have been countless flight accidents caused by bird strikes on aircraft in history. The occurrence of bird strikes, a frequent and dangerous event, can cause serious economic losses in mild cases, while in severe cases, aircraft damage and human death can result in unimaginable consequences. According to statistics, over 90% of bird strikes occur in airports and airspace near airports. Due to the fast flight speed of aircraft, collisions with flying birds often cause great damage, and in severe cases, can lead to aircraft crashes. Currently, the International Aviation Federation has upgraded bird strikes to a category "A" aviation disaster, which is one of the important factors threatening aviation safety.

  
  

  
  

The method of bird repelling at airports is to use a high sound pressure transducer array to achieve long-distance directional propagation of high-strength sound waves, and effectively drive away potentially threatening birds and birds through high-intensity noise stimulation. During the takeoff or landing phase of an aircraft, strong sound directional equipment emits a directional bird repelling sound wave with a beam angle. As the aircraft rises and falls, the equipment can adjust the direction up, down, left, right, and left to accurately drive away potential birds and birds around the aircraft. Due to the equipment's sound transmission distance reaching up to 2000 meters, which far exceeds the frequency of bird strikes, greatly improving the efficiency of bird repelling.
