A single-stage shaped charge structure capable of forming a joint action of piercing and bursting

Abstract

The invention discloses a single-stage shaped charge structure capable of forming a time-sequence combined effect of piercing and blasting. Under the action of the low detonation velocity charge and the control of the spherical structure, the active drug cover of the present invention forms a trailing explosive molding projectile EFP, and the trailing detonable active EFP is also activated during the molding process, and a violent explosion occurs during the macroscopic flight. chemical reaction; at the same time, under the action of high detonation velocity charge and under the control of the "cone + truncated cone" structure, the metal powder cover of the present invention forms a high-speed precursor metal rod flow, which flies in front of the detonable active EFP, thereby forming a precursor metal rod flow. The series penetration body composed of rod flow and trailing detonable active EFP. In this way, the precursor metal rod flow first uses the kinetic energy to penetrate the target and form a pre-perforation, and then follows the detonable active EFP into the target, and then uses the trailing detonable active EFP to produce a violent deflagration reaction inside the target, causing aftereffect damage Enhanced effect, so as to take into account the depth of penetration and aftereffect.

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...

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
