Annular shaped charge cutting system

Abstract

The invention relates to an annular shaped charge cutting system which comprises a shell, a charge, a shaped charge cover, a pressing block, a fuze and an explosion propagation network, the shell, the charge, the shaped charge cover and the pressing block jointly form a shaped charge unit, the fuze and the explosion propagation network form an explosion propagation network system, the shell is of an annular structure, and the charge is arranged in the shell. The annular shaped charge cutting system is large in action area and high in hit precision, and the hit probability is greatly improved; the effective burst height range is large; and the mass of a single damage element is large.

Description

technical field [0001] The invention relates to the technical field of explosively formed projectiles, in particular to a ring-shaped shaped charge cutting system. Background technique [0002] Generally, when the cone angle of the liner of the shaped charge warhead is greater than 90°, for example, the range of the cone angle is between 120°-160°, the liner does not form a jet under the detonation load, but A short and thick high-speed penetrating body is formed, that is, Explosively Formed Projectile (EFP). Explosively formed projectiles were called Self-Forging Fragment in the early days, sometimes also called Misznay-Schardin Warhead, Ballistic Disk, P Charge ), etc., the drug type can be a large cone-angle drug-shaped cover, a spherical-shaped drug-shaped cover, a rotary hyperbolic drug-shaped cover, etc. [0003] The prior art of application number CN201921082494.7 discloses a micro-explosively formed projectile, the diameter of the warhead is less than 2cm, the diam...

Problems solved by technology

[0003] The prior art of application number CN201921082494.7 discloses a micro-explosively formed projectile, the diameter of the warhead is less than 2cm, the diameter of the charge is not greater than 2cm, the height is not greater than 2.5cm, the velocity of the projectile is not less than 1000m / s, and the mass is not greater than 15g, which is configured to be mounted on a micro-drone. The problem to be solved is a highly integrated detonation device, which ensures the stability and safety of the detonation, ensures the detonation stability of the small-sized charge diameter, and forms a detonation device with certain damage. effect, high explosive height and flight stability, due to the limitation of structural size and charge, this structure forms a single interception mode of bullet hitting bullet, and the probability is almost zero

The lattice mode of multiple components is large in quantity, and the probability of interception is also very low; the prior art with application number KR1020170123104 discloses a molding device for explosively formed projectiles and a manufacturing method for explosively formed projectiles, which involves The explosively formed projectile is columnar. If the explosively formed projectile with this columnar structure wants to achieve the ideal interception effect, it needs to increase the amount of charge. The production cost of a single interception unit will greatly increase, and the above structures are not suitable for incoming projectiles. body interception
