Bullet throwing and separating device and method for precision guided fire extinguishing bomb

Abstract

The invention discloses a bullet throwing and separating device and method for a precision guided fire extinguishing bomb. According to the bullet throwing and separating device, an air bag and fire extinguishing bullet groups are arranged on the outer shell of the device, and the fire extinguishing bullet groups are arranged around the air bag; the air bag is connected with a gas generator, the air bag is expanded through the gas generator, and the air bag extrudes the fire extinguishing bullet to penetrate through the outer shell to avoid ejection, so that the purpose of high-altitude fire extinguishing is realized. The device disclosed by the invention is low in cost, simple and compact in structure, high in loading coefficient, low in throwing overload, and easy to design and operate.

Description

technical field [0001] The invention belongs to the field of distributing submunitions of fire extinguishing bombs, and in particular relates to a device and method for distributing and separating bullets of precisely guided fire extinguishing bombs. Background technique [0002] The precision-guided fire extinguishing bomb has high efficiency and accurate strike, and can be widely used in oil depot fires, chemical plant fires, high-rise fires, forest fire rescue, etc. The fire-fighting efficiency of precision-guided fire-fighting submunitions is more efficient. In practical applications, it uses the advantage of the number of bullets to carry out large-scale coverage of firefighting. In this process, the throwing technology of fire extinguishing bullets is particularly critical. At present, the submunitions throwing technology can be divided into three forms according to the throwing power source: inertial kinetic energy throwing, mechanical separation throwing, and throwi...

AI Technical Summary

Problems solved by technology

Since there is no additional power source to provide power, this throwing method is not practical when throwing at low or ultra-low altitudes; mechanical separation throwing is through the weight of the bullet itself, the guide rod spring or the pull spring and other mechanisms during the throwing process of the bullet. The function of giving bullets and parent bombs the component force of separation, this kind of structure is more complex, the cost is higher, and the price / performance ratio of fire extinguishing sub-munitions is too low; the propulsion method of throwing medicine gas is to rely on the high-temperature and high-pressure gas released by the combustion of gunpowder or explosives to push the bullets Throwing away from the mother body can obtain a higher bullet throwing speed and a controllable throwing spread, which is a widely used throwing method for sub-cluster bullets
