Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a perforated bullet,

The present invention relates to a penetrating ballast and a penetrating carbon having the penetrating ballast capable of improving the tongue hardness and the bullet penetrating ability by providing a penetrating ballast having a bullet shear core using a tungsten carbide alloy and a bullet rear end core serving as a weight compensating bulb .

As is well known, through-shot (ie, helmet) refers to a special-purpose shot made to penetrate tanks, warships, and concrete bunkers.

For example, the through-hole can be divided into a heavy-duty armor, a separable armor, a fleece armor, and a wing-stable separation armor. In the case of a light armor, a bullet is made of a light metal such as copper, By having a shim, it has a high kinetic energy, and thus it can provide relatively higher penetrating force than the previous penetrating shot.

In addition, the split armor is composed of penetrators connected to four detachers to maximize the penetration force while using a similar mass of bullets, thereby reducing the weight of the penetrators. However, by concentrating the kinetic energy in a relatively narrow area, It is possible to increase the speed of rotation relatively to increase the penetration force.

In the case of the hair iron armor charcoal, tungsten is used as a penetrator, and a cap made of copper is put on the head of the penetrator to contact the glove of the target first, thereby preventing the bullet collapse and improving the penetrating power.

On the other hand, in the case of the wing stable separation armor, it is called a nickle (or salted barrel separated type) and consists of a penetrator equipped with a stable wing and four pieces of detachment which pushes the bull inside the barrel by explosive force. By using bullets as a metal with high specific gravity and high strength, such as steel, tungsten, etc., not only the penetration ability can be improved, but also the stability wing can catch the trajectory and improve the accuracy.

The through-hole as described above is manufactured using tungsten carbide alloy as the material of the tanzanite core, and research and development of penetrating carbon having excellent hardness and penetration ability of the penetrating tanzers is continuously being carried out.
