Bird-repellent bomb specially for airport

Abstract

The invention discloses a bird-repellent bomb specially for an airport, which comprises a bomb body and a propellant, wherein the bomb body is a truncated cone-cylinder, the upper half part has a truncated cone structure and the lower half part has a cylinder structure; a layer of moisture-proof coating coats the outer surface of the bomb body; the center of the bottom surface of the cylinder structure is provided with an inner concave propellant cavity; the propellant cavity, on the whole, is a groove body in a truncated cone structure with a small upper part and a large lower part, and the propellant cavity is filled with the propellant; and the port of the propellant cavity is sealed by using non-woven fabric. According to the bird-repellent bomb disclosed in the invention, the overallstructure of the bomb body is improved, the resistance in the rising process of the bomb body is reduced, and the flying speed is improved; as the outer surface of the bomb body is coated with celluloid gum, moisture prevention is achieved, and the flammability is improved; the propellant is sealed in the propellant cavity by using the non-woven fabric dipped in the celluloid gum, the ignition rate of the propellant is increased, the explosion and scintillation effects of the bird-repellent bomb are effectively improved, visible light is generated, and as birds are afraid of the explosion andscintillation visible light, a bird-repellent role is played; and after the whole bomb body burns, no residual exists, the environment is protected, environmental pollution is reduced, the explosion and scintillation rate is high, and bird-repellent effects are improved.

Description

technical field [0001] The invention relates to a pyrotechnic product, in particular to a bird-repelling bomb used to drive away birds in the air above an airport. Background technique [0002] Repelling birds over military or civilian airports is mainly to protect the safety of take-off and landing of aircraft or aircraft, and to prevent birds from being sucked into the engine when the aircraft or aircraft takes off and land at high speed, or to cause accidents caused by hitting the body, landing gear, windshield, etc. Thereby, take certain measures to prevent bird invasion in the key flight area of ​​the airport, especially the runway or taxiway where the aircraft takes off and lands. Traditional bird repelling methods include auditory intimidation, visual deterrent, direct hunting, ecological or radar early warning, etc., among which bird repellent bombs are currently the most used. [0003] Bird-repelling projectiles are a kind of bird-repelling means, mainly to frighte...

AI Technical Summary

Problems solved by technology

The use effect of existing bird-repelling bombs is not ideal, and some will have residues to fly down after the explosion. Although they can drive away birds, they will cause pollution to the airport environment and will also have an impact on the progress of the aircraft; Defects in the installation position of explosives can easily form dud bombs or have a high explosive power, which poses a safety hazard; some of them add chemical substances to the propellant to make it produce peculiar smell after the explosion, which not only affects the birds, but also affects the surrounding atmosphere. environment, so its use is not satisfactory
