The Father of the Tungsten Alloy Armor Piercing Projectiles Won The National Highest Science and Technology Award

In the morning of January 8th, the national science and technology award conference in 2017 was held in Beijing. Wang Zeshan, a 83 year old Chinese Academy of engineering and professor of Nanjing University of Science and Technology, won the national highest science and Technology Award in 2017. He contributed his 60 years of scientific research to the fire and explosive and made the original achievements beyond the level of foreign countries. The contribution to the research of explosives is called "China's Nobel".

The Academician Wang has participated in a number of key national defense projects and made outstanding contributions to the development of China's military industrial explosive products. Several achievements have made our country's military industrial explosive industry the best in the world. This is the "reusing technology of overstock and retired explosives" (the first prize in the national scientific and technological progress award of 1993) "low temperature coefficient of propellant, loading technology and processing technology" (won the first prize of the National Technical Invention Award in 1996) "far range and module launches" (a national technical invention in 2016). Award) and "low overload propellant technology".

Wang Zeshan is also one of the main designers of domestic artillery and new tungsten alloy armor piercing projectiles. The main battle tank in our country uses a 125 millimeter tank gun. Wang Yuan's "far range and module launching and charging" technology is the key technology for the artillery to achieve "high efficiency damage, accurate strike, quick response and fire suppression". After the invention of this technology, the firing range of our artillery can be increased by more than 20%, and the ballistic performance is full.

China's third phase tungsten alloy armor piercing shell is also one of Wang Zeshan's research achievements. The three phase tungsten alloy penetrator penetration ability can be described as "extremely scary". According to the design requirements, the new ammunition has the ability to destroy any modern tank at a distance of 2500 meters. It is said that in a certain limit penetration test, the projectile has also created penetration depth near 4 digits. According to Western calculation, the performance index of the three phase projectile is a 700 mm uniform steel armor of about 700 mm in 2000 meters, and its maximum penetration depth is more than 1050 millimeters.

The three stage armor piercing core belongs to the high density tungsten alloy, which has large density, excellent thermal stability and large section density. It is beneficial to improve the speed of flight and the penetration ability to the steel plate. Moreover, the thermal stability of tungsten alloy is good. If the charge is not hot enough, it will stick together and not reach the role of armor piercing. The characteristics of tungsten alloy make it the first choice for making armor piercing projectiles.

The largest recognition feature of the three stage armor piercing projectile is the core free cap with a full tungsten x node instead of the previous hood and piercing body, and the streamlined head is shorter. Compared with the two phase projectile, the three stage pressure gradient of the chamber is small, the kinetic energy of the muzzle is greatly improved. The muzzle velocity of the armor piercing projectile has been greatly enhanced and the armor piercing power is more powerful. In addition to the 125 millimeter of the current 99A and 96A main battle tanks in our country, the three phase tungsten alloy piercing projectile has also developed a 105 millimeter calibre to adapt to the new light.

China's fire and explosive technology is excellent, just because there are many researchers and teams like Wang Zeshan, who are unheard of. Now, the honorary old academician is ambitious to the new goal, and we look forward to the team led by Wang Zeshan to create more scientific research.
