Single-stage shaped charge structure capable of forming penetrating and blasting time sequence combined effect

Abstract

The invention discloses a single-stage shaped charge structure capable of forming a penetrating and blasting time sequence combined effect. Under the action of low-detonation-velocity charge and the control of a segment-shaped structure, an active shaped charge liner forms a trailing explosive forming bullet EFP, the trailing explosive active EFP is also activated in the forming process, a violent chemical reaction occurs during macroscopic flight, meanwhile, under the action of high-detonation-velocity charge and the control of a cone and circular truncated cone structure, the metal shaped charge liner forms high-speed precursor metal rod flow, and the trailing explosive active EFP flies forwards, so that a series-connection detonation penetration body composed of the precursor metal rod flow and the trailing explosive active EFP is formed, thus, the precursor metal rod flow firstly conducts penetration on a target through kinetic energy and forms a pre-perforated hole, the trailing explosive active EFP enters the interior of the target, then the trailing explosive active EFP is utilized to generate a violent deflagration reaction inside the interior of the target, an aftereffect damage enhancement effect is caused, and therefore the penetration depth and the aftereffect effect are both considered.

Description

technical field [0001] The invention relates to the technical field of shaped charges, in particular to a single-stage shaped charge structure capable of forming a time-sequential joint action of piercing and blasting. Background technique [0002] In future ground warfare, concrete / reinforced concrete protective hard targets represented by protective fortifications and aircraft bunkers will play an increasingly important role. Whether such protective hard targets can be effectively destroyed is the key to gaining the initiative in war The essential. More importantly, the fundamental goal of striking concrete / reinforced concrete protected hard targets is not just to penetrate the concrete / reinforced concrete protection, but to efficiently damage the equipment and personnel inside the target. [0003] Currently, fortified bombs are the main equipment for dealing with concrete / reinforced concrete protected hard targets. Traditionally, the attack bomb has a two-stage series s...

AI Technical Summary

Problems solved by technology

[0004] However, with the development of ammunition technology, the above-mentioned traditional attack ammunition is facing some technical difficulties, which are mainly manifested in: (1) It is difficult to adapt to the development of ammunition miniaturization

Due to the two-stage series structure of the traditional attack bomb, there are many key components, such as the main-level energy-gathering warhead, the main-level fuze, the explosion-proof device, the follow-up killing bullet, the bullet fuze, etc., which are essential for the miniaturization of the ammunition. presents technical challenges

(2) The structure of the traditional two-stage tandem structure is very complex, and the design process needs to consider key technologies such as front and rear two-stage explosion-proof, front and rear two-stage fuze cooperation, etc.

(3) The types of target strikes are very limited

However, the technology of active liner is also facing a bottleneck problem. The active liner is made of energetic composite materials. After effects, but the penetrating ability is seriously insufficient

Specifically, the active drug-shaped shaped charge is only suitable for hitting thin concrete / reinforced concrete targets at a small angle of attack. Capable charges will not be able to penetrate concrete / reinforced concrete targets, which restricts the application of active drug-shaped covers on fortified shaped energy warheads
