Super Weapon Swap System

"Qin Guan, what do you think of our next generation of tanks?" after dinner in the 8640 army, Qin Guan and Zhu Lao sat at a big table again and began a new conversation.

Zhu Lao looked at Qin Guan with expectant eyes. It was obvious that major Yang had communicated with Zhu Lao. Zhu always valued the ideas put forward by Qin Guan.

Moreover, now, the negotiations on the introduction of leopard-2 tanks are at an impasse. Hans hopes that Han will introduce thousands of tanks before talking about technology export. For Han, it can import up to 10 tanks, lacking foreign exchange!

Since Qin Guan can get the American Sheridan tank through special functions, can you get a leopard-2 tank for everyone to study?

Zhu Lao's idea is this, but now, Qin Guan has just had the experience and his thinking has become more smooth.

The development of industrial system and industrial technology is the most important. Qin Guan can exchange equipment in the weapon system only by himself. Maybe later, when his system is upgraded to extremely powerful, he can exchange the equipment of the whole division into an organic system at once. But now, improve his own industrial level so that he can produce a large number of equipment, Is the top priority.

Thinking of this, Qin Guan already remembered something.

"For a tank, the most important thing is its firepower." Qin Guan said: "our next generation of tanks, whether they intend to use 120mm caliber or 125mm caliber, are inseparable from the manufacturing technology of gun barrel, among which electroslag remelting steel and barrel self tightening technology are the most important."

As long as we talk about tank guns, we can't do without these technologies.

Electroslag remelting steel is a method of smelting by using the resistance heat generated when the current passes through the slag as the heat source.

In other words, the purpose of remelting steel is to improve metal purity and ingot crystallization. The steel remelted by electroslag has high purity, low sulfur content, less non-metallic inclusions, smooth ingot surface, clean, uniform and dense, and uniform metallographic structure and chemical composition.

In fact, this technology existed in the 1950s, as did Xiong Guo. However, there is no advanced electroslag remelting steel.

The quality of electroslag ingot depends on reasonable electroslag remelting process and equipment conditions to ensure electroslag process, and this kind of steel is the inevitable choice for manufacturing tank gun. It will be known from later generations that almost all gun barrels are of this technology.

As for the self tightening of the barrel, it is to twist the barrel with a hydraulic press or other machinery. The plastic deformation layer by layer is generated inside the barrel due to the huge torque, which gives the barrel a huge inward stress. This stress was originally enough to disintegrate the gun, but because the gun steel was quite flexible, it maintained the gun from disintegration.

This stress pulls the fire gun to collapse internally, but it is pulled by the tensile performance of the gun itself, so there is a high prestress in the gun, up to hundreds of MPa. When the gun is fired, because the gas not only pushes the ammunition forward internally, but also has a great force to support the gun barrel. This force is opposite to the prestress in the gun barrel, Therefore, the barrel self tightening process greatly improves the bore pressure bearing capacity of the gun.

Both methods are to make the tank barrel bear high chamber pressure, and the result is that the shell has greater kinetic energy when it flies out.

When Qin Guan proposed these two technologies, Zhu Lao frowned.

Qin Guan did not directly talk about the leopard-2 tank, but directly mentioned the artillery. After all, for the tank, there is no suitable artillery. Everything is useless. Without these two technologies, there is no hope of production.

The layman watches the excitement and the expert watches the doorway. When Qin Guan says this, he points to the most painful place. You say that the armor is not thick enough and the engine is not strong enough. The tank soldiers can stand these. However, if the tank gun can't break through the enemy's tank armor, the tank soldiers fart!

"Yes, these two technologies are the most important, but I'm afraid we can't reach this level in China now." even if Zhu has always advocated self-research and thought that foreign help is unreliable, Zhu also knows that relying on his own level of domestic research and development is far away.

"But if we import, we don't have so much foreign exchange reserves, and we don't know where to import it," Zhu said.

It's not easy to introduce these technologies!

"It can be imported from NiuGuo," Qin Guan said. "The 105mm linear bore gun developed by NiuGuo has been used as standard equipment by their whole western group."

105mm linear bore gun is the standard gun of the whole western group in the whole era. It is powerful enough to deal with the threat of bear country. It is a quite mature gun.

"We have negotiated with Niu Guo to introduce these rifles. At the same time, we have introduced various processing equipment for the production of these rifles, including electroslag remelting steel related equipment for gun barrel, precision deep hole drill, high-speed rotary forging equipment for the production of armor piercing ammunition, etc. as long as these equipment are available, we will study our own new generation of tank guns and have technical reserves."

What Qin Guan is talking about now is a project in the history of previous generations. The introduction of 105mm tank gun is not an isolated project, but a set of very complex systems. Based on this system, 86 type 100mm smooth bore anti tank gun, 89 type 120mm smooth bore anti tank gun and 125mm tank gun are all developed on this basis, and it goes without saying that tungsten alloy and uranium alloy armor piercing shells.

What our side wants is a larger caliber tank gun as the pre research of the next generation of tanks. Now, it is much easier to find the West and find NiuGuo to introduce the main equipment in active service. At the same time, even if it is a 105mm gun that is no longer advanced technology.

When Qin Guan said this, the people present nodded: "yes, this is a good way, but this method still requires us to pay a lot of foreign exchange reserves. Our country has no money!"

Zhu Lao is a little helpless. Introducing dozens of guns does not require much foreign exchange. However, to introduce the whole system, Niu people may not export, or lions may open their mouth, which makes the country unbearable. In the end, the project still fails.

"We can exchange technology," Qin Guan said. "For example, it will be much easier for us to exchange technology with the design drawings of 1500 horsepower engine."

NiuGuo's tank gun technology is good, which can greatly improve its own side, but NiuGuo also has their weaknesses. Look at the Challenger tanks of later generations. Chobam armor makes its weight more than 60 tons, but it only has its own 1200 HP diesel engine. In contrast, Hans is 1500 HP now!
