What's the working method of the tail-stabilized de-hull penetrating bullet
1. The power of the tail-stable de-hull penetrating bullet derives from the kinetic energy (velocity, mass) and the physical properties of the shell material itself when the shell hits the target。
2. In order to reduce resistance, armour-piercing munitions are designed in a shape conducive to reducing resistance and only to the effect of obstruction and gravity when they are discharged at an acceleration of the charge in the chamber。
3. Armour-piercing ammunition consists of light-quality cartridges, which are packed in the middle with the same calibre as the cannon. Armour-piercing bullets were made into thin rods, detached after the discharge and continued to fly。
4. The tail-stable de-hull penetrators are fitted with four tail wings in the tail to ensure the smoothness and precision of the body during flight。
5. Armour penetrators are usually made of more dense, hard-hard, high-temperature-resistant metals, such as tungsten carbide and depleted uranium, to ensure that they are not easily bent upon collisions with the battered armour and to maintain the strength of the cartridge。
Armour-piercing munitions impact tank armour with their own kinetic energy, and the impact of high-speed armour-piercing munitions on tanks is well beyond the absorption limits of the armour and can penetrate in a robust manner。
7. The outer core of the tail stabilizer de-hull penetrating bullet/apfsds is similar to a long arrow with a diameter of 20-30 mm and a long long-term ratio of more than 20:1. This approximate long arrow shape not only reduces flight resistance, maintains speed, but also has a small impact and a high impact on the impact of the armour and can effectively increase the depth of the armour。
8. The diameter of apfsds is much smaller than the calibre of the gun and must be placed on the core of the bullet to be fired by the gun. The effect of the belt is to keep the chamber closed and increase the area of the projectile to the point where the projectile receives the first speed of the cannon。
9. At present, apfsds in the west has an initial velocity of about 1,700 m/s, with a thin copper cortex wrapped around the outside of the belt, which frictions with the gunpowder and the barrel as the projectile ejected, which splits and falls with air resistance after the shell ejected, while the remaining arrow cores continue to fly at high speed。
10. Apfsds is completely kinetic to the destruction of armour, making the kinetic energy and material hardness of the core the most important performance indicator. In order to cross the tank armour, the bulletballs must have a high hardness, the greater their kinetic energy, the greater their armour-piercing power。
