Problems solved by technology

[0002] Exploring ammunition with high-efficiency damage is an important development direction in the field of conventional ammunition. For targets such as oil tanks, oil tankers, and armored vehicles facing future battlefields, traditional charge warheads have difficulties in reliably igniting oil and ammunition. How to achieve efficient damage to these targets is a difficult problem that the ammunition industry needs to solve urgently.
Traditional warheads mainly rely on armor-piercing effect when striking targets such as tanks and armor, with a single damage effect and low damage capability

Embodiment 1

[0041] The following describes the calculation and experimental results of an active energy-containing composite charge-type cover shaped charge structure for the equivalent target of steel ingots and oil tanks. In this embodiment, the cone angle of the buffer medicine type cover 3, the active energy-containing medicine type cover 4, and the penetrating medicine type cover 5 is 130°, the buffer medicine type cover 3, the active energy-containing medicine type cover 4 and the penetrating medicine The thickness of the mask 5 is 0.03 times the maximum diameter of the charge. The composition of the active energetic drug type cover 4 is that the mass of aluminum powder accounts for 26%, and the mass of polytetrafluoroethylene powder accounts for 74%. The material of the shell 1 can be steel, and the material of the buffer type cover 3 and the penetration type cover 5 is copper.

Abstract

The invention relates to a shaped charge structure for an active energy-containing composite shaped charge liner. The shaped charge structure comprises a shell, charge, a buffering shaped charge liner, the active energy-containing shaped charge liner and a penetration shaped charge liner, all of which are of axis symmetric structures. The shell is a combined structure of a circular truncated cone and a cylinder. One end of the cylinder structure is sealed through the circular truncated cone structure. The combined structure of the circular truncated cone and the cylinder is filled with the charge. The other end of the cylinder structure is sequentially provided with the buffering shaped charge liner, the active energy-containing shaped charge liner and the penetration shaped charge liner, and the buffering shaped charge liner, the active energy-containing shaped charge liner and the penetration shaped charge liner are used for sealing the charge into the shell. Each of the buffering shaped charge liner, the active energy-containing shaped charge liner and the penetration shaped charge liner is in a spherical segment shape, and the conical angle of the spherical segment ranges from 10 degrees to 175 degrees. The shaped charge structure has a perforating function and also has a detonation-like effect, and the detonation capability on ammunition, the ignition capability on fuel, the burning stifling actions on personnel and the transverse damaging effect on targets of the shaped charge structure are far stronger than those of an inert shaped charge liner.

Description

Technical field [0001] The invention belongs to the technical field of ammunition engineering, and in particular relates to an active energy-containing composite charge-type cover shaped charge structure. Background technique [0002] Exploring ammunition with efficient damage is an important development direction in the field of conventional ammunition. For the future battlefields of oil tanks, tankers, armored vehicles and other targets, the traditional charge warhead is difficult to reliably ignite fuel, and difficult to reliably detonate ammunition. How to achieve efficient damage to these targets is a problem that the ammunition industry needs to solve urgently. Traditional warheads mainly rely on armor penetration when attacking targets such as tanks and armors, with a single damage effect and low damage capability. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an active en...
