Background technique

Since the invention of the aircraft by humans, bird strikes have become one of the important factors threatening aviation safety. With the development of aviation technology, the speed of the aircraft continues to increase, and the high-speed movement makes the destructive power of the bird strikes reach an alarming degree. The lighter causes the aircraft to be damaged and causes property damage; the heavy machine destroys people and causes a major disaster. According to the statistics of the International Air Transport Association for many years, there are about 10,000 bird strikes per year in the world. Bird strikes are the first major cause of flight accidents. The International Air Transport Association has upgraded bird damage to “A”. Aviation disasters.

At present, there are two ways to prevent bird collisions in the aviation industry: First, improve the strength of aircraft materials and enhance their ability to resist bird strikes. For example, high-intensity cockpit glass is used, and engine parts are designed and manufactured to take into account the ability to resist bird strikes. The second is to reduce the overlap between bird activities and aircraft landing and landing areas. Such as the use of gas cannons, terror eyes, recording and bird hunts, hunting and raptors, and bird repellers in the landing and landing field; keeping away from birds or unsuitable for bird life in airport site selection, airport construction, airport environment, etc. . However, the above two methods have the following problems: 1.
