Still tapping into potential?

A penetration depth of 300 millimeters sounds like a lot of strength, but if you look at the current situation, you know that this armor-piercing ability is still far from enough.

The data on the armor of various countries are classified, however, the data of the general analysis, the thickness of the armor of the tanks of the Soviets, the turret, is estimated at four hundred millimeters.

Tanks, firepower first! For tank crews, there is no highest armor-piercing ability, only higher, constantly tapping the potential of their own tank guns!

"If you want to continue to improve the potential of tank guns, you can do so in several ways." Qin Zhenhua didn't feel that this request was unreasonable, he was continuing to talk about his thoughts, at this time, several people at the table were all red-faced, with excited wine in their mouths, and with an expectant look in their eyes, looking at Qin Zhenhua.

"First of all, in terms of the core of the armor-piercing projectile, the length-to-diameter ratio will be further improved." Qin Zhenhua actually had ideas to improve for a long time, so now, with the help of wine, he also took advantage of the situation to express his thoughts, and he always felt that it was more comfortable here than in the tank factory.

Of course, because of the difference in positions, tank factories are more often to ensure safety, and in combat units, the main thing is to ensure combat effectiveness!

"This is an important indicator of armor-piercing bullets, the higher this length-to-diameter ratio, the greater the armor-piercing ability, the Soviet armor-piercing bullets are thick and short, so the armor-piercing performance is not high, ours, the core of today's armor-piercing bullets is slender, so the performance has been greatly improved."

"Of course, this can't be improved indefinitely, first of all, the material, the slender pole is easier to break, the strength of the material is not enough, and secondly, it is aerodynamics, the slender pole may change its trajectory in the air, these are not something I can solve alone, and it requires the cooperation of materials science and aerodynamics." Qin Zhenhua said.

They are not omnipotent, among them, the material is the most reflective of the industrial base, their own imitation of the equipment, why not as good as the original equipment? It's because the materials don't meet the requirements.

"Secondly, there are tank guns." Qin Zhenhua said: "Our tank gun, if we can use electroslag remelting steel and self-tightening technology, we can significantly increase the chamber pressure of the tank gun, and the higher the chamber pressure bears, more charges can naturally be used, and the speed at which the cannon ejects the barrel increases, which is naturally more powerful." ”

Electroslag remelts steel, and the body tube is self-tightening?

"Among them, electroslag remelting is to melt our steel ingots for the second time, electrify the high-resistance slag, and generate a large amount of heat energy, so that in the process of metal melting, carbon, sulfur, phosphorus and other impurities continue to become electroslag precipitation, and finally obtain high-quality gun steel with dense structure, uniform composition and small heterogeneity." Looking at the few people in front of him who didn't seem to understand, Qin Zhenhua explained concisely.

"As for the self-tightening of the body tube, it is to use mechanical, hydraulic and other methods to apply pressure to the inner wall of the body tube to make it plastically deformed, while the outer layer retains elasticity. To put it simply, when the barrel is cast, it is pushed inside again to make the inner layer of the barrel more dense, which will produce residual compressive stress, which can offset the tensile stress of gunpowder gas, thereby enhancing the pressure-bearing capacity of the barrel. It can also delay crack propagation and improve the fatigue resistance of the body. ”

Qin Zhenhua held chopsticks in his hand and gestured at the wine glass.

"We don't have any of these technologies." Luo Ronggen has been a military representative in a military factory for many years and is very familiar with technology.

"Yes, so we need to bring it from abroad as soon as possible." Qin Zhenhua said: "In short, after using these techniques, our 100 slip, I think we can eventually increase to 400 mm of penetration." ”

These processes are the most commonly used barrel manufacturing processes in the West, but there is no one in China, and the domestic 100 slip is only produced from the production line of the rifled gun of the 59 tank, as long as the last step is not rifled, it is done.

The old man held the glass in his hand, but he didn't move, obviously thinking about something.

In this overseas investigation, these problems must be solved!

What should be introduced, must be introduced, so that it can reach a depth of 400 mm, which is really good! However, it's only 400 millimeters, which still doesn't feel perfect, and when you dig to 400 millimeters, it's probably the end, right?

"Is there a way for us to continue to tap into the potential?" Hearing the old man's words, Bi Liansheng felt that the old leader was a little difficult for a strong man, and it had already reached 400 millimeters, wasn't it enough?

"Yes." Qin Zhenhua replied solemnly.

"What is it?" The old man is more interested, don't look at Qin Zhenhua's young age, but this vision is really not simple.

In the previous era, many people liked to brag and put satellites at every turn, but the result? The troops are the least likely to be fooled, in previous years, the troops were not even willing to receive tanks, and most of what they received were problematic, and it has only gotten better in recent years.

At least better than the Air Force, the planes received by the Air Force did not dare to fly at all, and the quality was not up to par.

Qin Zhenhua, relying on real strength, the last time he went to the tank factory, the old man saw that Qin Zhenhua is really capable, today, he has confirmed his ability, the big hole in the steel plate with a thickness of 200 millimeters, can not be faked, so, now he says that the depth of 400 millimeters, the old man also dares to believe it, as for higher?

The old man was curious.

Everyone is looking forward to Qin Zhenhua's answer, only Wang Erzhu has no such concerns, he is still using a knife to cut the roasted whole sheep, Wang Erzhu, who was born in the grassland, is the best at doing this, cut it down, and put it on a plate for everyone, so that it is convenient to eat.

"Bigger up the caliber." Qin Zhenhua said.

"Poof." What is this called a solution?

I thought Qin Zhenhua had any good way, it turned out to be a magnified caliber! When you don't have enough firepower, switch to a thicker barrel.

Tanks are also following this path, the barrel is constantly thickening, especially in the USSR, which has begun to adopt a caliber of 125 mm.

"We used to have a three-liquid experimental prototype, didn't it use a 120 mm caliber gun? At the same time, the next generation of the West also uses the caliber of 120 mm, so I suggest that we continue to study the 120 mm tank gun as the main gun of our next-generation standard tank when we tap the potential of the 100 slip. ”

Qin Zhenhua's face was full of confidence: "I believe that if we use a 120 mm tank gun, with our long-rod warhead, it should be no problem to hit 600 mm armor." ”

The old man fell into deep thought again.

If you put on a larger caliber artillery, there is a greater penetration depth is certain, Qin Zhenhua said that the 600 mm, it is also possible to reach, however, your own 69 tank can't bear it, if you carry a new barrel, it means that you have to get a new tank!

Sure enough, Qin Zhenhua spoke: "Uncle, in the maintenance workshop of our first machine factory, we want to submit a war petition to develop a second-generation medium tank..."

What a big breath!

Seeing everyone's reactions, Qin Zhenhua could only hurriedly follow: "Relevant components, including main guns, hydraulic transmissions, walking devices, etc. ”

This is pretty much the same, if you have a maintenance workshop and want to make the main battle tank out, it must be Yelang arrogant.
