Description

Technical Field

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

[0002] High-altitude bird repellent bombs primarily work by stimulating birds' senses to repel them. Sound and light are the most common stimuli. Some bombs emit high-decibel sounds or flashing lights to startle birds and force them to leave the area. Other bombs release an unpleasant odor or chemical substance that makes birds uncomfortable. These stimuli are all effective in repelling birds, thereby preventing bird infestations.

[0003] Bird strikes are a painful experience for pilots. The impact of a bird colliding with an aircraft traveling at 370 kilometers per hour is like a cannonball hitting the aircraft head-on. Statistics show that over 80% of bird strikes occur during takeoff, landing, and low- and ultra-low-altitude flight. Therefore, it's crucial to install bird-scaring cannons at airports to effectively repel birds.

[0004] Existing bird-repellent 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 backward 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 the windshield.

[0009] Hard fragments may cause the windshield to shatter. After the windshield is broken, 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 vision and affect driving safety.

[0010] 3. Hard debris 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 metallic debris on aircraft

[0012] During a civil aircraft's flight, there are three primary ways to communicate with the ground: radio voice communication, radar signals, and air-to-ground data links. The combined effects of these three methods ensure a safe and reliable flight.

[0013] During the process of wireless signal transmission on an aircraft, fragments containing metal components will cause the impedance of the receiving device to shift in frequency, resulting in a significant decrease in the transmitting and receiving capabilities of the receiving device itself.

[0014] Furthermore, metal-containing debris absorbs the signals radiated by the receiving device, severely impacting signal transmission. This is because metal fragments absorb some of the energy in the air, reducing the energy conversion efficiency of the entire communication system and thus affecting communication effectiveness.

[0015] 5. Impact of debris on airport runways

[0016] Debris affects the cleanliness of the runway and increases the workload of cleaning staff; chemical debris may react with rain or snow, causing runway corrosion, reducing runway 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.

[0044] In order to further illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] like Figures 1 to 4As shown, the utility model provides an environmentally friendly airport bird-repellent bomb, which includes a detonable bomb body 1 made of a nitroazole or aminoazole compound material. The head of the bomb body 1 is structured with a mounting groove 101, and a fuse body 2 for detonating the bomb body 1 is installed in the mounting groove 101.

[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 projectile 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 projectile to be launched along the barrel path.

[0048] Specifically, the mounting groove 101 is cylindrical.

[0049] Specifically, 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.

[0050] Specifically, the aminoazole compound material is any one of 5-amino-1-ethylpyrazole, 5-amino-1-methyl-1H-pyrazole, 5-aminoindazole or 5-amino-1-methyltetrazole.

[0051] Furthermore, the fuze body 2 includes a shell 201 made of a hard, combustible organic material, a charge 3 disposed within 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 as the projectile 1 explodes.

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

[0056] The control chip 403 is used to store the delay time information inputted from the input terminal 402 . The control chip 403 can send a discharge instruction to the capacitor 404 according to the stored delay time signal.

[0057] The capacitor 404 is used for discharging to make the electric heater 405 connected to the charge 3 generate heat energy. The electric heater 405 is used for generating heat energy to ignite the charge 3. The charge 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. The delay time is calculated according to the flight altitude of the bird (applicable to birds of different flight altitudes).

[0060] Furthermore, the projectile body 1 is of streamlined design, the head of the projectile body 1 is in a cone shape, and the tail is provided with a cone-shaped groove 102 .

[0061] Furthermore, the outer surface of the elastic body 1 is completely covered with an antistatic coating.

[0062] Specifically, the anti-static coating is a Teflon electrostatic coating, which is applied to the surface of the projectile through a process to form a uniform and dense protective film. This coating not only prevents the generation and accumulation of static electricity, but also effectively reduces the friction coefficient of the projectile surface.
