Chapter 117 We are going to develop the second generation tank (repair)
Still exploring potential?
A penetration depth of three hundred millimeters may sound very strong, but if you look at the current situation, you will know that this armor penetration capability is still far from enough.
The armor data of various countries are confidential, but according to general analysis data, the armor thickness of Soviet tanks and turrets is estimated to be over 400 millimeters.
Tanks have the first firepower! For tank soldiers, the armor-piercing ability is not the highest, only higher. Constantly tap the potential of your own tank guns!
"If you want to continue to improve the potential of tank guns, you can go through these aspects." Qin Zhenhua did not think this request was unreasonable. He continued to talk about his ideas. At this time, several people on the table were blushing.
, with the smell of excitement in his mouth, and his eyes looking expectantly at Qin Zhenhua.
"First of all, in terms of the core of the armor-piercing projectile, we should further improve the aspect ratio." Qin Zhenhua actually had ideas to improve it for a long time, so now, drunkenly, he took advantage of the situation and expressed his thoughts. He always felt that here
, more comfortable than in the tank factory.
Of course, it is because of the difference in stance. The tank factory is more often about ensuring safety, while in the combat troops, the main thing is to ensure combat effectiveness!
"This is an important indicator of armor-piercing bullets. The higher the length-to-diameter ratio, the greater the armor-piercing ability. The Soviet armor-piercing bullets are all thick and short, so the armor-piercing performance is not high. As for ours, today's
The core of the armor-piercing bullet is slender, so the performance is greatly improved."
"Of course, this cannot be improved without limit. The first is the material. Slender poles are easier to break and the material is not strong enough. Secondly, it is aerodynamics. The trajectory of a slender pole may change in the air. These
, it cannot be solved by me alone, it requires the cooperation of materials science and aerodynamics." Qin Zhenhua said.
You are not omnipotent. Among them, materials are the most important part of the industrial foundation. Why are your imitation equipment not as good as the original equipment? It is because the materials do not meet the requirements.
"Secondly, it's the tank gun." Qin Zhenhua said: "If our tank gun can use electroslag remelted steel and barrel self-tightening technology, the tank gun's bore pressure can be significantly increased, and the bore pressure it can withstand will be higher.
, naturally more charges can be used, and the speed of the cannon ejecting from the barrel increases, which naturally increases the power."
Electroslag remelting steel, body tube self-tightening?
"Among them, electroslag remelting is to melt our steel ingots twice, energize the high-resistance slag, and generate a large amount of heat energy. In this way, during the metal melting process, carbon, sulfur, phosphorus and other impurities are continuously precipitated into electroslag.
Finally, we get high-quality gun steel with dense structure, uniform composition and small heterogeneity." Seeing that several people in front of him didn't seem to understand, Qin Zhenhua explained concisely and comprehensively.
"As for the self-tightening of the barrel, it means to use mechanical, hydraulic and other methods to apply pressure on the inner wall of the barrel to plastically deform it, while the outer layer retains elasticity. To put it simply, when the barrel is cast, it is pushed on the inside again.
Making the inner layer of the gun barrel denser will produce residual compressive stress, which can offset the tensile stress of the gunpowder gas, thereby enhancing the pressure-bearing capacity of the gun barrel. It can also delay the expansion of cracks and improve the fatigue resistance of the barrel."
Qin Zhenhua held chopsticks in his hand and gestured towards the wine glass.
"We don't have these technologies." Luo Rongen has been a military representative in a military factory for many years and is very familiar with technology.
"Yes, so we need to introduce it from abroad as soon as possible." Qin Zhenhua said: "In short, after using these technologies, our 100-slip force can eventually be increased to a penetration depth of 400 mm."
These processes are the most commonly used gun barrel manufacturing processes in the West, but they are not available in China. The domestic 100-slide is only produced from the production line of the 59 tank rifled gun. As long as the rifling is not pulled in the last step, it will be made.
.
The old man's hand was holding the wine glass, but he didn't move. He was obviously thinking about something.
During this study abroad trip, we must solve all these problems!
What should be introduced must be introduced. It can achieve a penetration depth of 400 millimeters, which is really good! However, it is only 400 millimeters, which still feels imperfect. When the excavation reaches 400 millimeters, it will probably be over, right?
"Is there any way we can continue to tap our potential?" Hearing the old man's words, Bi Liansheng felt that the old leader was a bit pushy. It has already reached 400 millimeters. Isn't it enough?
"Yes." Qin Zhenhua replied solemnly.
"What is it?" The old man was more interested. Although Qin Zhenhua was young, his vision was really not simple.
In the past, many people liked to brag and would launch satellites at every turn. But what happened? The troops were the least likely to be fooled. In the past few years, the troops were not even willing to receive tanks. Most of the ones they received were
There is a problem, and it has only gotten better in the past few years.
At least it's better than the Air Force. The aircraft received by the Air Force don't dare to fly at all, and the quality is not up to standard.
Qin Zhenhua relies on real strength. Last time he went to the tank factory, the old man saw that Qin Zhenhua was really capable. Today, he has proven his ability. The big hole in the two hundred millimeter thick steel plate,
But there is no way to fake it, so now that he says the penetration depth is four hundred millimeters, the old man dares to believe it. As for higher?
The old man was curious.
Everyone was looking forward to Qin Zhenhua's answer. Only Wang Erzhu didn't have such worries. He was still cutting the roasted whole lamb with a knife. Wang Erzhu, who was born in the grassland, was the best at doing this. He cut it and put it on the plate for everyone.
, which is convenient to eat.
"Increase the caliber." Qin Zhenhua said.
"Pfft." What kind of solution is this?
I thought Qin Zhenhua had some good method, but it turned out to be to enlarge the caliber! When your firepower is not enough, then change to a thicker barrel.
Tanks are also following this path. The gun barrels are constantly getting thicker, especially the Soviet Union, which has begun to use 125 mm caliber.
"We used to have a three-liquid experimental prototype, and didn't it use a 120mm caliber gun? At the same time, the next generation of the West also uses a 120mm caliber, so I suggest that we tap the potential of the 100mm
, continue to study the 120mm tank gun as the main gun of our next-generation standard tank."
Qin Zhenhua's face showed confidence: "I believe that if we use a 120mm tank gun and use our long warhead, it should be no problem to hit 600mm of armor."
The old man fell into deep thought again.
If a larger-caliber artillery is installed, it will definitely have greater penetration. The 600 mm mentioned by Qin Zhenhua is also possible. However, our own 69 tank cannot carry it. If it carries a new barrel, then
This means that we need to install a new tank!
Sure enough, Qin Zhenhua spoke: "Uncle, the maintenance workshop of our No. 1 Machinery Factory wants to issue a challenge to develop a second-generation medium tank..."
What a loud tone!
Seeing everyone's reaction, Qin Zhenhua could only continue quickly: "Relevant parts, including the main gun, hydraulic transmission device, walking device, etc."
This is more or less the same. If you, a maintenance workshop, want to tinker with a main battle tank, you must be arrogant.
