Technical Field

The invention belongs to the technical field of military equipment, and particularly relates to a transverse bursting armor piercing composite bullet with simple structure, strong penetrating power and large killing surface.

Background

A bullet is an ammunition fired by a firearm. The common bullet is composed of shell, primer, propellant powder and bullet head. When the bullet is shot, the firing pin of the firearm impacts the primer to burn the propellant powder, and gas is generated to push out the bullet. Currently, warheads are generally classified into general warheads and armor piercing warheads, which are usually made of copper or plastic coated copper steel as a shell, and are usually in a streamlined design with a slender bullet tip and a boat-shaped tail cone to reduce air resistance and increase penetration force or penetrating power.

The armor-piercing bullet is a bullet which mainly relies on the powerful kinetic energy and high strength of a bullet head to forcibly penetrate an armor to destroy a target. As soon as the armor piercing bullet touches a hard target such as a steel armor, a pit is formed on the surface of the hard target, and the steel armor and the like on the bottom surface of the pit are ejected out like a plug so as to achieve the aim of piercing armor. In the prior art, in order to improve the armor piercing capability of an armor piercing bullet, the improvement of a propellant powder, the improvement of a bullet structure, the improvement of the hardness and the structure of a bullet core in the bullet are started, so that the speed of the bullet, the hardness of the bullet core and the armor breaking form are improved, and although certain effects are obtained, the explosion pressure and the chamber outlet speed of the bullet are difficult to obviously improve due to the limitations of the structure, the material and the shooting precision of a firearm, so that the change of the hardness and the structure form of the bullet is generally started. In the prior art, in order to improve the armor breaking capacity of armor piercing bullet heads, the bullet cores are generally made of high-hardness and high-density tungsten and tungsten carbide materials, so that the kinetic energy of the bullet cores is improved, the deformation of the bullet cores after the bullet cores meet targets is reduced, and the potential energy loss is reduced. In order to further improve the penetration capability of the core, a multi-section series structure core is adopted, the high-strength core is adopted at the first section, and then high-density and low-cost cores such as lead columns are adopted, so that the problems of insufficient density, higher cost and insufficient kinetic energy of the first section of the integral tungsten core and tungsten carbide core are solved, but when the core armor is adopted, the lead core at the rear part is bulged due to the compression force, the diameter of the lead core is larger than that of a hole formed by the front high-strength core penetrating through the armor, so that the momentum of the lead core is transferred to the surface of the armor due to deformation on the surface of the armor, and the purpose of improving the kinetic energy of the first section of the high-strength core is difficult to achieve. Therefore, in the prior art, a non-connected split structure is adopted among a plurality of sections of serially connected cores, and the cores behind the first section are made of relatively high-strength materials, so that the phenomenon that the momentum is transferred to the surface of the armor due to overlarge deformation of the cores at the rear section when the bullet is struck can be avoided, the kinetic energy of the cores at the rear section can be transferred to the cores with the sharply reduced speed at the first section, and when the cores at the rear section pass through the hole in the armor due to the non-connected split structure, the phenomenon that the hole blocks the cores at the rear section due to rebounding of the armor to influence the movement of the cores at the first section can be avoided, so that the nail breaking capacity of the cores can be effectively improved. Although the armor-breaking capability of the tandem-type bullet core is improved, the situation that the armor-breaking effect cannot be achieved due to the fact that the armor-breaking capability is only point-killing damage and the breakdown is difficult in the continuously developed armor technology is urgently needed to be solved.

Disclosure of Invention

The invention aims to provide a transverse bursting armor piercing composite bullet with simple structure, strong penetrating power and large killing surface.

The invention is realized by the following steps: including shell, first refill, prefabricated band, initiating explosive, initiating device, the shell has streamlined nose, first refill is fixed to be set up in the shell of nearly nose, the rear portion of first refill is provided with the explosive chamber, the initiating explosive is fixed to be set up in the explosive chamber, initiating device is for triggering formula initiating explosive device and fixed the setting in the rear end of explosive chamber, prefabricated band encircles fixed the shell surface that sets up in nearly explosive chamber and is provided with prefabricated broken piece groove, the hardness of first refill is higher than the shell, the hardness of prefabricated band is not higher than the shell.

The invention has the beneficial effects that:

1. according to the invention, the initiating explosive and the initiating device are arranged at the rear part of the first bullet core, so that after the first bullet core is landed, the initiating explosive is detonated due to the huge inertia of the initiating device to generate energy-gathered explosion, and the first bullet core obtains higher kinetic energy to puncture an armor target; and because the first bullet core is made of high-hardness materials, the first bullet core has small deformation when meeting an armored target, has less loss potential energy and can further improve the armor breaking capacity.

2. According to the invention, the prefabricated elastic band is arranged on the shell outside the initiating explosive, the initiating explosive is detonated when the bullet is shot on hard objects such as body armor, helmet and the like, and the soft prefabricated elastic band and the shell are transversely cracked and splashed by the explosion energy, so that hands, feet and lower jaws which are difficult to protect by personnel can be damaged, and the killing surface is effectively improved.

3. The invention adopts the trigger type initiating device to ignite the initiating explosive at the rear part of the bullet core, so that the explosion phenomenon can be effectively avoided and the use safety is better because the trigger type initiating device is difficult to directly ignite the initiating explosive even if the propellant of the bullet is neglected to be loaded or fails.

4. The rear part of the shell is also provided with a second bullet core which is separated from the first bullet core, the hardness of the second bullet core is higher than that of the lead core, and when the first bullet core impacts the armored target, the second bullet core can resist being compressed to form bulges so as to avoid the bulges from diffusing along the surface of the armored target, so that the kinetic energy of the second bullet core is transferred to the first bullet core; and the first core phase and the second core are arranged at intervals, and the first core phase and the second core phase are substantially independently acted after the first core impacts an armor target, so that the phenomenon that the second core is blocked due to rebound of the armor to influence the motion of the first core can be avoided, and the second core forms rear-end resistance after the primary explosive between the first core phase and the second core is exploded, thereby increasing the explosive impact force acted on the first core, achieving the effect of improving the potential energy of the first core, and further improving the penetrating power of the first core.

In conclusion, the invention has the characteristics of simple structure, strong penetrating power and large killing surface.
