Fuse capable of improving grazing impact and self-destruction reliability

Abstract

The invention discloses a fuse capable of improving grazing impact and self-destruction reliability. On the basis of the original standard product design, a piston type part (such as a support barrelor a shearing barrel) capable of sliding axially is additionally arranged at the head of the fuse, the piston type part is pushed to move axially by the aid of target fragments produced when the fusecollides with a target or ground sediments during landing, a self-destruction spring is compressed, then a firing pin is pushed to trigger a detonator, the explosive sequence is detonated, and projectile detonation is realized. Meanwhile, the piston type part capable of sliding axially can stop foreign matters such as the ground sediments and the like from entering an inner cavity of the fuse to hinder movement of the firing pin when the fuse lands (particularly grazes), the firing pin stabs the detonator reliably, and the reliable grazing impact effect of the fuse is guaranteed. The fuse is simple in structure, and few changes are made on the original structure.

Description

technical field [0001] The invention belongs to the fuze technology, and in particular relates to a fuze which improves the reliability of the ground-wiping explosion and self-destruction. Background technique [0002] Equipped with a fuze with the function of wiping the ground, it can improve the damage efficiency of the projectile to the target and reduce dud bombs. However, when the ammunition equipped with trigger fuze touches the ground at a smaller drop angle, it often has the problem that it cannot be fired reliably. The fuze head of a small-caliber aerial artillery grenade warhead is only sealed with a moisture-proof sheet. When the fuze hits the ground (especially when it touches the ground at a small corner), sand and sand will pour into the fuze head, thereby hindering the movement of the firing pin, making it impossible to Sting the detonator normally, causing the fuze to misfire. The firing rate of the small drop angle of the projectile with these two fuzes is...

Problems solved by technology

However, when the ammunition equipped with trigger fuze hits the ground at a smaller drop angle, it often has the problem that it cannot be fired reliably.

The fuze head of a small-caliber aerial artillery grenade warhead is only sealed with a moisture-proof sheet. When the fuze hits the ground (especially when it touches the ground at a small corner), sand and sand are poured into the fuze head, thereby hindering the movement of the firing pin, making it impossible to Sting the detonator normally, causing the fuze to misfire

The projectile with these two types of fuzes has a small drop angle and the firing rate is not high
