Abstract

The invention discloses a fire channeling prevention device for a fuel air explosive warhead. The device consists of an outer barrel, an inner barrel and an agent between the inner and outer barrels, wherein the inner and outer barrels are made from a metal material with higher ductility; the agent undergoes decomposition reaction to release a large amount of gas under the action of thermal or shock compression. The agent is compressed by shock waves generated after the detonation of a central dispersed explosive of the fuel air explosive warhead, and the shock waves can be attenuated by the agent, so that the amplitude of the compressed waves transmitted to an air explosive fuel is lower, and the air explosive fuel is prevented from being heated to burning temperature. After the agent undergoes decomposition reaction to release gas such as CO2, H2O and NH3 after being shocked and compressed, the gas is between a central dispersed explosive detonation gas product and the air explosive fuel, and the high-temperature detonation gas product is separated from the air explosive fuel by the gas, so that the air explosive fuel is prevented from being burnt after the central dispersed explosive of the fuel air explosive warhead is detonated, and the problem of fire channeling is solved.

Description

technical field [0001] The invention relates to a cloud explosion warhead, in particular to a fire prevention device for a cloud explosion warhead. Background technique [0002] FAE warhead is a surface-kill warhead with high energy efficiency. [0003] For the secondary detonation FAE warhead, its action process can generally be divided into two stages: the first stage is the formation of FAE cloud, that is, the fuel throwing stage; the second stage is the detonation stage of FAE cloud. During the formation of the FAE cloud in the first stage, if the ignition and combustion of the cloud occurs before the secondary fuze acts, it is called a jump fire. The occurrence of jumping fire greatly reduces the power of FAE, which is one of the important ways for FAE to fail. In order to give full play to the power of FAE weapons, it is necessary to prevent the occurrence of fire. [0004] There is no technology about FAE fire prevention at present. [0005] Practice has shown tha...
