The Second Machine Factory has always been behind the One Machine Factory. Every time the leader goes to the Grassland City to inspect, he must go to the First Machine Factory first and then to the Second Machine Factory. In recent years, the Second Machine Factory has not done nothing. They have finally found a lot of experience and a lot of solutions.
Just study Qin Zhenhua more!
Now, after some research, Xie Huimin learned the experience.
This time, our self-propelled anti-tank gun should be the protagonist! The 120mm tank gun has been rejected, but at present, it is still the most powerful tank gun in China, and its power is even greater than the current 125mm tank gun!
After all, the 125mm tank gun has just begun testing, and the charge amount is not too much. The penetration depth of only 450mm has already completely satisfied Lao Ba. It can be seen that in terms of firepower, his side has indeed developed and has already emerged from the shadow of the past.
In terms of chamber pressure, the 125mm tank gun has only reached a stable chamber pressure of 470 MPa, while the 120mm tank gun on its own has stabilized at 560 MPa. Of course, as the 125mm gun continues to tap its potential in the later stage, it will definitely be increased to 560 MPa, or even higher, reaching 600 MPa, which should be no problem.
However, that's all for the future. For now, the 120mm cannon is already the most mature one.
The armor-piercing ability reaches 500 mm, which is definitely true, but there is still room for improvement in this data!
Now, looking at everyone's surprised expressions, even Qin Zhenhua showed a surprised expression. Xie Huimin's heart was also very happy at this moment. OK, I saw it, this is what I want!
Xie Huimin was satisfied.
"Yes, in our tests, we could reach up to five hundred millimeters, but now, in order to continue to dig deeper into its potential, we have used the latest materials."
"Is it depleted uranium?" After hearing Xie Huimin's statement, Qin Zhenhua finally remembered this.
On the road to tungsten alloy armor-piercing bombs, we have been studying tirelessly that the domestic tungsten ore is quite rich and we don’t care about these consumptions. However, the characteristics of tungsten alloys are always incomparable to depleted uranium.
One of the characteristics of depleted uranium is its self-sharpness. During the process of piercing armor, other cores are becoming more and more blunt, and only depleted uranium is becoming more and more sharp as it gets!
So, not to mention anything else, just replace the material of the core with depleted uranium, which can be improved a lot!
Moreover, this also solves the problem of nuclear waste. After all, nuclear reactors will produce a certain amount of nuclear waste. How to deal with these wastes has always been a difficult problem. If it can be used, it is of course the best.
However, it is not easy to make depleted uranium alloy. Just like tungsten alloy, special processes can achieve hard and strong results. How to smel and cast depleted uranium alloys in the present are all difficult.
It seems that it is our own material department that has made a breakthrough!
There is also a history of research on depleted uranium alloys in China. After studying them for many years, they have been unknown. Now, it seems that they have finally put on a big move.
(Check the information, it is said that during the Battle of the Bangzi Kingdom, the 85mm cannon we used on the T-34 tank had depleted uranium bombs? We also swear to say that we were letting it off on CCTV. However, the heroes of East China felt suspicious. At that time, the Soviet Union had just detonated the atomic bomb. They had the energy to get the depleted uranium bombs? The Americans only matured their technology in the 1980s, right?)
"It's a special alloy No. 4." Xie Huimin said. This title is a bit taboo after all.
"Okay, let's test it." Mr. He said: "Our army has been calling for the king for so many years. Now, we can finally be the king of firepower."
"Yes, test it once, but Mr. He, we want to change the target this time." Xie Huimin said.
Change the target?
When everyone heard this statement, they were stunned again.
OK, this time, the second machine factory has been playing tricks! Qin Zhenhua also sighed that he did not prepare too much this time and did not intend to steal the limelight of this self-propelled anti-tank gun. However, Xie Huimin and the others did this, which really made Qin Zhenhua feel a little impressed, and they would play like this too!
"Now, gap armor has begun to become popular," Xie Huimin said: "Our target is fixed, with a set of 100 mm thick steel plates, and then apart from the back half a meter, and then a second piece is placed. We have already made this target, as long as it is fixed on the shooting range here, it will be fine."
The times are developing and technology is advancing. Nowadays, the armor is composite armor, layer by layer. Now, when we are shooting targets, we must do this, layer by layer, between the two layers, air is used as a barrier, which forms the lowest level of gap armor.
"Okay, approval." Mr. He said.
This is not just a fraud, but a raising difficulty. Mr. He is of course satisfied with this.
So, another car driven by the Second Machinery Factory drove towards the target and began to be arranged.
"Okay, Lao Xie, you will definitely perform very well today." Qin Zhenhua said.
"Yes, of course it's very beautiful, but if you go to the scene and watch from the side, it's even more spectacular." Xie Huimin said.
In the past, the target was a thick target, either wearing it or not. Although the process of piercing the armor was magnificent, it was all inside and could not be seen. Now, you can finally see the process in the middle, which must be very spectacular.
"Okay, this is simple." Qin Zhenhua said: "Driving our wheeled infantry fighting vehicle, stop on the side and watch from the nearby. Hello, can you make sure you aim, right?"
With a depth of 550 mm, dozens of 551 armored vehicles can be strung with candied haws on the side. So, Qin Zhenhua has to make an agreement in advance. If it is hit by mistake, the consequences will be terrible.
"You should be one hundred meters away, the upper hand." Xie Huimin said.
The 120mm tank gun has a very high accuracy. If it is one thousand meters, the error will not be greater than 0.26 meters x 0.26 meters. However, when driving a wheeled infantry fighting vehicle, there will definitely be various leaders inside. Therefore, in order to avoid accidental attacks, it is more appropriate to go 100 meters away.
As for the wheeled infantry fighting vehicle proposed by Qin Zhenhua, Xie Huimin could also know why. So, he also reminded him of the position of the upper wind!
"Well, we still have to open the overpressure three-defense system." Qin Zhenhua said, opening the back door of his wheeled infantry fighting vehicle: "Dear leaders, who wants to see it in person?"
