1959: Carrying the achievement system, she rolled

Time passed in a hurry and soon it was January 1th, which is also the Little New Year in the north.

At the test firing range, the gun barrel of the Type 59 tank was adjusting its position. A 300 mm thick steel plate stood upright a kilometer in front of it.

The defensive power of armored steel is 2.5 times that of steel plates, and the armor of the front of the Type 59 tank is 100 mm.

After many considerations, the thickness of the steel plate was set at 300 mm. The purpose of their test firing was that as long as they could penetrate this 300 mm steel plate, the tungsten alloy armor-piercing projectile they developed would be considered a success.

Now that the test firing of tungsten alloy armor-piercing projectiles has reached the final stage, Director Song is reluctant to take out the armor steel.

You know, when he was developing high-carbon alloy armor-piercing bullets, although he was reluctant, he still took out a piece in the end.

Director Song was also helpless. It was not that he was stingy, but the institute simply did not have that much funding.

Now not only is he bald, but even Lao Yang has started to lose his hair, and he asked him what methods he has for maintaining his hair.

If he had his way, he wouldn't have to wear a hat all day.

It can be said that a tungsten steel alloy armor-piercing bullet is equivalent to several months' salary for him.

This is still under the condition of trying hard to suppress costs, otherwise the cost will be even higher.

Everyone at the test firing range had their eyes fixed on the Type 59 tank, and everyone's faces were filled with tension and excitement.

"Prepare……"

"emission……"

Tungsten steel alloy armor-piercing bullets whizz out from the muzzle under the action of high temperature and high pressure gas in the barrel.

If you watch a slow motion camera, you will find that when the armor-piercing bullet contacts the steel plate, the surface of the steel plate will be concave at first, unable to withstand it, and finally break.

When facing armor-piercing bullets, the extremely hard steel plates are like tofu dregs, and the steel plates will explode after being penetrated.

When the projectile hits the steel plate, the projectile breaks and the core continues to penetrate the armor. The moment the core penetrates the steel plate, the entire core also begins to explode, mixing with the fragments of the steel plate.

These deadly fragments are the real weapons of armor-piercing bullets. When armor-piercing bullets penetrate the armor steel of the tank, fragments of the bullet core and armor steel will also appear inside the tank.

Tungsten steel alloy armor-piercing bullets use these fragments to kill personnel in armored targets and destroy equipment inside tanks.

The core is the main body of the armor-piercing projectile, made of tungsten steel alloy, while the body is made of low-carbon steel. A guide belt is installed on the body to enable the core to rotate and stabilize during flight.

Because of the high hardness of the bullet core, it does not deform when penetrating armor, but it will form fragments after penetrating the armor.

These fragments are the most lethal weapons.

They used tracers and magnesium and other materials to add a tracer tube to the tail of the armor-piercing bullet.

Its function is to display the trajectory of the ballistic missile and help locate the target position.

When a shell is fired, materials such as tracers and magnesium use the friction of the air to produce a chemical reaction, causing the tail of the armor-piercing shell to emit a bright light.

When confronting the enemy, you can use the bright light of the tracer tube to determine the direction of attack and force deployment.

Especially when fighting at night, the tracer tube is the eyes of the armor-piercing bullet.

Tungsten steel alloy armor-piercing bullets can penetrate the armor steel on the front of the tank's body, but they also have a disadvantage, which is that when the hit angle is large, ricochets will occur.

"It went through..." Operator Huang Yamin shouted excitedly, so excited that his mouth suddenly tightened, causing him to gasp.

For this operator position, he lost all his brothers again.

You can get along with your brothers again even if you lose them, but you only have one chance to witness a miracle, so he still knows what is more important.

"It's done..." Du Yimeng, who had been observing the outside through the observation port, said with a happy face.

From this moment on, when they encountered tanks on the battlefield, they no longer needed to wander around and try to find targets to attack.

They can charge head-on, and tungsten steel alloy armor-piercing bullets are their confidence.

Even though she has the blueprints, some parts cannot be manufactured with current technology and can only be replaced with other materials. The key is to control the manufacturing cost.

After working on it for so long, I finally got it done.

Today is the Little New Year, and the Chinese New Year is just a few days away, but she's still staying at the research institute. If she can't figure it out, she'll have to spend the New Year there.

"Congratulations to the host for developing a tungsten steel alloy armor-piercing projectile. Reward: 500 attribute points and a blueprint for a 100mm tungsten alloy armor-piercing discarding sabot projectile."

Research skills: Primary (100/100), Intermediate (1000/1000), Advanced (954/), King (0/), God (0/)

Du Yimeng opened the panel attributes. The system rewarded her with a total of 150 attribute points for her last first-class merit and promotion to the next level. Adding to the original 304 points, her advanced attributes have reached 954 points.

With 500 more attribute points, I clearly feel that I have a better understanding of scientific research.

If she had been constantly crushing Wan Ping before, now she no longer bothered to crush him, because her level had risen again.

If you are not on the same level, there will be no sense of accomplishment.

Finally, she thought of the system's reward. If she continued her research, she wondered if Director Song could bear it?

You probably can’t bear it!

Director Song has been very anxious during this period!

In fact, the most important thing is that even if we continue to study, with the current level of technology, the power of this tungsten alloy armor-piercing discarding sabot projectile will not be too great.

……

The moment the cannon was fired, Director Song closed his eyes. The saying that a cannon shot is worth a fortune is absolutely true.

Not only Director Song, many people closed their eyes, but it was a subconscious conditioned reflex.

After the smoke cleared, everyone's eyes were fixed on the steel plate.

"Success..." As the person recording the data shouted, everyone excitedly pounded their fists on their palms.

"Okay, okay, okay..." Director Song said okay three times with a smile on his face. If he was not a man with strong willpower, he might not have been able to hold on.

It's too expensive...

"Our tanks finally have weapons that can attack head-on."

This news filled the entire institute with joy and pride.

It's like two people fighting, the opponent is holding a long sword, while they only have a short sword.

As soon as they swung their short swords, the opponent's long swords pierced their vital points. How could they continue the fight?

But now it's different, they are now also people holding long swords. No matter what era, face is given by oneself.
