Fuse energy-gathered jet flow power-enhanced booster tube internally provided with isolation block

Abstract

The invention discloses a fuse energy-gathered jet flow power-enhanced booster tube internally provided with an isolation block. The fuse energy-gathered jet flow power-enhanced booster tube is mainly used for detonating insensitive charge of an insensitive warhead and comprises a shaped charge liner, a booster tube shell, a main explosive roll, an auxiliary explosive roll, the isolation block and a reinforcing cap, wherein the isolation block is coaxially arranged between the main explosive roll and the auxiliary explosive roll, and the waveform of detonation waves can be adjusted in the detonation propagation process of the booster tube, so that the explosion load is improved, the jet velocity is increased, and finally the detonation power of the shaped charge liner and the booster tube is improved. When the fuse booster tube is applied to insensitive ammunition, the inert isolation block can also absorb energy of accidental stimulation such as baking, bullets, fragments and jet impact, the baking resistance, gun impact resistance, fragment impact resistance and jet impact resistance of the fuse booster tube are improved, and the insensitive state can be achieved easily. According to the fuse energy-gathered jet flow power-enhanced booster tube, the axial detonating power of the booster tube is enhanced, and meanwhile the explosive loading amount can be reduced, so that the incidental explosion hazard and the manufacturing cost are reduced.

Description

technical field [0001] The invention belongs to the fuze technology, in particular to a fuze energy-gathering jet power-enhanced booster tube with a built-in isolation block, which is mainly used for detonating insensitive warheads with insensitive charges, and can also be used for conventional warheads by reducing the amount of booster charge Thereby reducing the incidental explosion hazard or reducing the demand occasions of manufacturing cost. Background technique [0002] The fuze booster is located at the output of the fuze and is used to detonate the projectile or the main charge in the warhead. The classic booster structure generally includes a booster shell, a booster charge, and a reinforcing cap. The classic booster tube structure is not a big problem when it is used to detonate ordinary projectiles or non-insensitive charges in warheads, but it may have insufficient detonation power when it is used to detonate insensitive projectiles or insensitive charges in war...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of fuze energy-concentrating jet power boosting booster tube with built-in isolation block, which solves the problem of lack of power that may occur when the classic booster tube structure is used to detonate insensitive projectiles or insensitive charges in the warhead. problem, as well as the problem of high cost due to the excessive amount of explosives contained, and the problem of high incidental explosion hazard
