Description

Technical Field

[0001] The invention belongs to the technical field of ammunition, and in particular relates to an environmentally friendly airport bird-repelling bomb. Background Art

[0002] The working principle of high-altitude bird repellent bombs is mainly to repel birds by stimulating their senses. Among them, sound and light are the most common stimulation methods. Some high-altitude bird repellent bombs will emit high-decibel sounds or flashing lights to scare birds and force them to leave the area. In addition, some bird repellent bombs will release an odor that is unpleasant to birds or release a chemical that makes birds feel uncomfortable. These stimulation methods can effectively repel birds and achieve the purpose of preventing bird infestation.

[0003] "Bird-to-aircraft accidents" are a hidden pain in the hearts of pilots. The impact force generated by a bird colliding with an aircraft flying at a speed of 370 kilometers per hour is like a "cannonball" hitting the aircraft head-on. According to statistics, more than 80% of "bird-to-aircraft accidents" occur during the takeoff, landing, and low-altitude and ultra-low-altitude flight stages of the aircraft. Therefore, it is necessary to install bird-repelling cannons within the airport to effectively drive away birds.

[0004] Existing bird-repelling bombs usually have a shell, which will produce a large number of fragments after explosion.

[0005] A large amount of debris residue will cause the following problems:

[0006] 1. The impact of debris on aircraft engines.

[0007] Aircraft engines have enormous thrust, and debris will be sucked in if it gets slightly close to the engine; the engine rotates at a high speed, and hard debris hitting the high-speed rotating fan blades may cause blade damage. After the blades are damaged, the debris will be thrown backwards into the "core engine" with the airflow, damaging the "compressor" blades and other components, causing more serious consequences; the large exposed surface of the engine of a civil airliner also increases the probability of inhaling debris.

[0008] 2. Impact of debris on windshield.

[0009] Hard fragments may cause the windshield to break, and after the windshield breaks, the hard fragments may also cause casualties to the pilot; at the same time, the accumulation of a large amount of debris will also affect the pilot's line of sight and affect driving safety.

[0010] 3. Hard fragments may also cause damage to other parts such as wings, tail, landing gear, radome, landing lights, etc., seriously affecting flight safety.

[0011] 4. Impact of metal debris on aircraft

[0012] During the flight of civil aircraft, there are three main ways to communicate with the ground: radio voice communication, radar signal and air-to-ground data link. Only with the joint action of these three methods can the entire flight journey be truly guaranteed to be safe and reliable.

[0013] During the process of wireless signal transmission by aircraft, fragments containing metal components will cause frequency deviation in the impedance of the receiving device, resulting in a significant decrease in the transmission and reception capabilities of the receiving device itself.

[0014] In addition, the fragments containing metal components have an absorption effect on the signals radiated by the receiving device, which will seriously affect the signal transmission. The principle is that the metal fragments can absorb part of the energy in the air, thereby reducing the energy conversion efficiency of the entire communication system, thus affecting the communication effect.

[0015] 5. Impact of debris on airport runways

[0016] Debris will affect the cleanliness of the runway and increase the workload of cleaning staff; chemical debris may react with rain or snow, causing runway corrosion, reducing the runway's service life and increasing maintenance costs; large hard debris poses a significant risk during aircraft takeoff and landing, which may cause serious damage to the aircraft and endanger lives.

[0046] Specifically, the elastic body is formed by using a prefabricated shape mold and a mechanical press molding method.

[0047] Furthermore, the size of the bird-repelling bullet can be adaptively adjusted according to the barrel of the selected bird-repelling gun. The inner diameter of the barrel of the bird-repelling gun is selected in the range of 15, 20, 25, 30, 35 or 40 mm. In this embodiment, the power of the bird-repelling gun comes from compressed air, and the gas volume expansion caused by the instantaneous release of compressed air drives the bird-repelling bullet to be fired along the barrel path.

[0048] Specifically, the mounting groove 101 is configured as a cylinder.

[0051] Furthermore, the fuse body 2 includes a shell 201 made of a hard combustible organic material, a charge 3 disposed in the shell 201 for detonating the projectile 1, and a control element 4 for igniting the charge 3. The shell 201 made of a hard combustible organic material can burn as the projectile 1 explodes.

[0052] Specifically, the drug column 3 is prepared from a nitroazole compound, and the nitroazole compound material is any one of 3-nitropyrazole, 4-nitroindazole, 5-nitroindazole, 6-nitroindazole, 7-nitroindazole, 3-nitro-1,2,4-triazole, 2-nitroimidazole or 4-nitroimidazole.

[0053] Specifically, the hard combustible organic material is celluloid or shellac, which can burn along with the explosion of the projectile 1 .

[0054] Furthermore, the control element 4 includes a substrate 401 installed in the housing 201. The substrate 401 is connected to an input terminal 402, a control chip 403, a capacitor 404 and a heater 405. The substrate 401 is a circuit board, and various elements are connected through circuits.

[0055] The input terminal 402 is signal-connected to an external controller, and is used to receive delay time information sent by the external controller. In addition, the input terminal 402 is also used to charge the capacitor 404 .

The electric heater 405 is used for generating heat energy to ignite the explosive column 3. The explosive column 3 is used for burning to detonate the projectile 1.

[0058] Specifically, a slot for embedding the electric heater 405 is configured on the medicine column 3 .

[0059] Specifically, the external controller is used to send a delay time signal to the control chip 403 to control the bomb 1 to be detonated after reaching the target altitude area.
