Bright Sword Military System

Chapter 1471

Wang Xuexin turned his attention to Luo Guangjian, the director of the artillery shell factory: "Director Luo, tell me why the smoothbore cannon can't hit far or accurately!"

Those present at the meeting are either researchers from the Artillery Factory or technicians from the Artillery Factory, and all they can bring are those with two brushes and some skills. They are all aware of the shortcomings of smoothbore guns. Commanded blindly, so some people frowned, some looked helpless, and some shook their heads slightly and sighed, but everyone didn't say anything because of Wang Xuexin's face.

"Regimental Commander!" Luo Guangjian explained: "The situation of the smoothbore gun is like this. Because it has no rifling, it will not rotate after being ejected from the chamber. If it does not rotate, it will lack stability. If the speed is slow, it will roll in the air, so it will not be accurate or far!"

Wang Xuexin didn't speak. He took out a stack of drawings of fin-stabilized sabot projectiles from the folder and handed them to the guards behind him.

This was prepared by Wang Xuexin before he came. He was worried that the on-site painting would make people suspicious: how can the data of things drawn by hand be so accurate?

If you prepare in advance, you can use the excuse of "one minute on stage and ten years of work off stage", anyway, no one knows that Wang Xuexin just took ten minutes to draw it and then asked the staff to draw a few more pictures according to the appearance.

The guards distributed the drawings one by one, and everyone looked at the strange thing on the drawing in a daze.

Qin Jian even asked: "Commander, are these... shells?"

Wang Xuexin explained: "As Director Luo said, the reason why smoothbore guns can't hit far is because the shells cannot be stabilized in the air. So, what if the shells are shaped like the long rods drawn in the drawings? It carries With the tail, can you maintain stability in the air? Can you hit far and accurately?"

"That's right!" Professor Su has a little understanding of this matter: "The tungsten mines are mainly located in Dayu County, Jiangxi Province. There are many tungsten mines dotted there, and most of my country's tungsten is produced there!"

"So!" Wang Xuexin said, "We can't make it break and we can't make it bend!"

"Having said that!" Luo Guangjian said, "But there is a problem with this long-stem shell. It will definitely break when it hits the enemy's armor, so it has no armor-piercing ability!"

Later, when Su Xin asked about it, Wang Xuexin replied: "I was just thinking... Why can't the cannonball hit far away with such a strong force, and the bow and arrow can be shot well even with human pull, and then I thought Such an arrow-like cannonball!"

After speaking, Su Xin glanced at Wang Xuexin, his eyes were full of doubts and shock, as if to say, "You guy, how did you come up with such a completely unconventional shell?"

This argument is plausible, Su Xin has to believe it... But, why does Wang Xuexin always think of it but others can't!

Professor Su immediately knew what to do: "Tungsten alloy, we want to use tungsten alloy to make this shell?"

If it is okay under the control of the stubborn army, then it is a matter of trading, but if it is under the control of the devils, it is impossible. The devils will not be stupid enough to sell this important strategic material to the Eighth Route Army.

But it is useless to scold now, Su Xin looked at Wang Xuexin with regret, this road seems to have entered a dead end again.

"That's not a problem!" Luo Guangjian replied: "The armor-piercing projectile is more important to be able to penetrate the armor of the enemy tank. If it can penetrate, even such a long pole will explode enough fragments to kill the personnel inside! Of course, It will not work against infantry personnel with such shells!"

This is because China still has the technology and equipment for smelting tungsten, and even there is no shortage of workers... The equipment and technology are all brought by Hans. The tungsten produced is mainly exported to Hans. Hans did this to increase production and facilitate its transportation. .

"Is Dayu County still under the control of the stubborn army?" Su Xin asked anxiously.

No one objected, because this did solve the problem of the flight stability of the shell.

In fact, it is not only Professor Su who knows about tungsten alloys, but most people in the conference room.

The reason is that China is a big tungsten-producing country. Before the war broke out, the annual output of tungsten reached 8000 to 9000 tons, accounting for 37% of the world's total output and ranking first in the world.

Professor Su sighed, shook his head and said, "Not long ago, during the Battle of Henan, Hunan and Guangxi, the recalcitrant army voluntarily withdrew from Dayu County, which has been controlled by devils!"

First of all, there are tungsten mines in Shanxi. Although the reserves are not large, they are enough for the Eighth Route Army, but they have not been discovered at this time.

Besides, if the tank is pierced with a hole, the internal instruments and equipment will always be damaged, right?At that time, the tank can still drive and fight normally?

After a while, Qin Jian asked: "But... can such a thin rod-shaped armor-piercing projectile be lethal when it hits the armor of an enemy tank?"

A lot of Hans' equipment in China was actually bought with these tungsten.

There was an instant scolding in the meeting room.

What Luo Guangjian said is correct. If the long-stem shell is divided into two or even several pieces from the middle, the energy will no longer be concentrated in one point but will be divided into several parts to hit the tank armor. If it is bent, it will hit the armor sideways. It is impossible to penetrate the target.

All Wang Xuexin has to do is call out the distribution of modern proven minerals from the system... It is easy to get the locations of three tungsten mines in Shanxi, one in Zhongtiao Mountain, one in Luliang Mountain, and one in XZ.

Soon Luo Guangjian asked another question: "But the tungsten mines are all in the south, we don't have any!"

Wang Xuexin nodded, and a heated discussion immediately erupted in the conference room.

Everyone nodded in agreement. Humans are actually very fragile. If the armor-piercing bullet hits like this, there will definitely be many high-speed fragments flying in the small space of the tank. A casual hit can kill half of the life.

But how could Wang Xuexin not think of this?

Su Xin said thoughtfully: "I think, compared with traditional armor-piercing projectiles, this long-shaft arrow-shaped armor-piercing projectile may have greater power, because all kinetic energy will be concentrated on this long rod, and it will be affected by the air force during flight." The resistance is very small, and the force area when hitting the target is also small. It can be imagined...it will fly farther, be more accurate, and have stronger armor-piercing ability than traditional armor-piercing projectiles! Even though it uses a smoothbore gun!"

At that time, Wang Xuexin only needs to send someone to check the corresponding location!
But of course, this matter will not be said at the conference.

"Let me handle this matter!" Wang Xuexin said: "Although the tungsten mine production area has been occupied by devils, the recalcitrant army has never stopped mining tungsten ore. I believe they must have reserves. We can import a tungsten mine from them first." Solve the urgent need! You only need to consider how to develop this new type of artillery and shells!"

"Yes!" Everyone responded.

The researcher who thought that Wang Xuexin was directing blindly also completely put away his contemptuous attitude.
