First Public Display of The Three - Phase Armor Piercing Projectile Made in China

In September 2017, the three phase 125/105 tungsten alloy armor piercing projectile was first displayed at the exhibition of Wang Zeshan academician education research achievements held at Nanjing University of Science and Technology.

The main battle tank of China has been used for 125 years in the 30 millimeter tank gun, which has been updated several times during this period. According to the domestic statement, it has 3 stages, the so-called one phase, two phase and three phase,, and the main designers are academicians Wang Zeshan. The third-generation tungsten alloy armor-piercing projectile independently developed by China is 125mm in diameter and 105mm in diameter. The 125mm caliber adapts to the current 99A and 96A main battle tanks in China. The 105mm caliber is the tungsten alloy armor-piercing arm, this 105-mm armor-piercing projectile broke through the limitations of 125-mm diameter auto-filling and has the advantage of greater power and faster autofilling, which may become the main direction for the improvement of the next generation of artillery in China.

The three phase tungsten alloy piercing projectile made in China was published in 2010. According to the design requirements, the new ammunition has the ability to destroy any type of modern tank at a distance of 2500 meters. It is alleged that in a limited penetration test, the projectile has also created near 4 digit penetration depth. We must point out that the penetration depth of the 1000 millimeter is actually deep penetration test. According to the Western computing mode, the performance of the three stage projectile is equal to 700 millimeters or 2000 millimeters, and the maximum penetration depth is more than 1050 millimeters.

The maximum shape of the three phase projectile is characterized by the core without the wind, and the shape of the projectile is only slightly different from the two phase. The main purpose of this is to be compatible with the 96A main battle tanks that are still generally installed in our country. So what are the advantages of the three stage armor piercing projectile compared to the previous two stages? It can be summed up in the following two points:

The first step: Advanced three bomb using tungsten X section instead of the head hood and body armor, and the composition of the streamlined short head. This structure substantially increases the length of the penetrator when penetrating the homogeneous target. When dealing with multi-target and NERA, it has the same effect as the armor piercing body: blocking / reducing lateral force's interference on the main penetrator.

The second step: Advanced improved propellant, novel penetrator with high pressure indicated efficiency of TEGDN propellant, pressure gradient curve, muzzle kinetic energy increases, which means the projectile muzzle velocity to a higher level, more powerful armor.

Tungsten alloy penetrator core is a tungsten alloy product with high density. It has high density, excellent thermal stability and large cross section density. It helps to improve the speed of storage and penetration ability to steel plate, and to increase the kinetic energy of armor piercing projectile, and to provide a fatal strike for armor. Moreover, high temperature resistant tungsten alloy; good thermal stability, in the process of flight penetrator with air friction produces a lot of heat, if the projectile in filling heat is not good it will be bonded together, can not achieve the penetrating effect, characteristics of tungsten alloy makes it become the preferred material for manufacturing armor bomb.

At present, the most powerful countries in the world are the United States, Russia and Germany. The accumulation of tank manufacturing technology in China is slightly less than that. But the bold innovation in the field of propellant makes our tank's firepower performance world-class. The tungsten alloy projectiles in China and the German DM63 tungsten alloy projectile and the American M829A4 depleted uranium bomb are called the top three of the world.

The depleted uranium ranked first, but similar to the The Golden Lion "seven injuries boxing, powerful but has something harmful. The highest level of Germany in the field of tungsten alloy penetrator has acknowledged in the world, the 2006 launch of the DM-63 tungsten alloy penetrators is considered to be the representative of the world of tanks and ammunition, its performance is often used as a benchmark for other countries, South Korea's APFSDS is copied in germany. To be proud of, China's new armor-piercing bomb design is the third generation of China's scientists from scratch, fumble step by step out of its performance and DM-63 flat, and Germany represent the world's most advanced level of tungsten alloy armor-piercing bullets.
