"Director Qin, what wind has blown you?" In the second machine factory in Grassland City, Nie Jianqiang warmly greeted him.
Qin Zhenhua worked non-stop, after arranging the engine, he came to the Second Machine Factory. The First Machine Factory and the Second Machine Factory were both in the grassland city. The relationship between us was quite harmonious. A few years ago, Xie Huimin retired.
Now Nie Jianqiang is taking the lead. Facing this old friend who has been dealing with for more than 20 years, Nie Jianqiang felt very moved.
"We are all in the grassland city, so we have to walk around more often. Unfortunately, I have been too busy with work in the past few years and have never been here. Please don't be surprised." Qin Zhenhua said.
Hearing Qin Zhenhua's words, Nie Jianqiang quickly shook his head: "Where is Director Qin, if you have anything to do, just give me an order. There is no need to be so polite."
Nie Jianqiang was very strange to Qin Zhenhua for being so polite. Although the second machine factory is also very powerful, it cannot be compared with the first machine factory. The first machine factory makes complete vehicles, the second machine factory makes artillery.
The cannons made by the machine factory are to be equipped with one machine factory. Today, Qin Zhenhua suddenly came here, and Nie Jianqiang felt a little surprised. What are they here for? Could it be that they are here to urge the 125mm tank gun to be modified?
?
Although the caliber is 125mm, the strength of tank guns is very different. The second machine factory started to build 125mm guns, and now it has undergone several performance improvements, some of which are used for 85mm guns.
Some are used on tanks on 96 tanks, and some are used on 99 tanks.
The tank gun of the 99 tank is much more powerful than the tank gun of the 85 tank. At the same time, the 99 tank is currently being modified, which also puts higher requirements for their tank guns, hoping to withstand a larger bore.
To have better ballistic characteristics, Nie Jianqiang always thought the other party came for this matter.
"Then I'll just say it." Qin Zhenhua said: "Have you ever had a technical innovation in the 105mm cannon in our factory?"
Nie Jianqiang was a little surprised when he asked this question. Why did he suddenly ask about the 105mm cannon?
Back then, the Second Machine Factory introduced the technology of the L7 tank gun and the supporting electric slag remelting steel, the self-tightening process of the body tube, etc., which improved the performance of the tank guns manufactured by the Second Machine Factory to a very high level, and finally it can
The Soviet tanks were penetrated from the front.
For a long time, the 105mm tank guns produced by the Second Machinery Factory were at the highest level in China. At the same time, the performance was constantly improving, the potential was constantly being explored, and the body tube was constantly being lengthened and changed to
In the end, he didn't even recognize his father.
However, the caliber is justice. In this era, the larger the caliber, the more face it is. Therefore, after the next generation of tank guns was selected, the second machine factory began to manufacture 125mm tank guns. By 105
The technology accumulated on millimeter tank guns uses 125mm tank guns, so although the caliber of the Russian tank guns is much more powerful than that of the Russian tank guns.
In this way, the 125mm tank gun appeared. After that, the technical update of the 105mm tank gun was put aside because the superiors kept giving them higher indicators to the 125mm tank gun, allowing them to rack their brains to improve.
There is no time to consider how the 105mm tank gun will be improved.
Now, when Qin Zhenhua suddenly asked about this, Nie Jianqiang must have found it a little strange.
"Well, there are still technical innovations. The main change we made is to reduce its recoil." Nie Jianqiang thought for a while, and then said to Qin Zhenhua: "This kind of improvement is for our 63A.
”
In China, the Type 63 tank is a special number. It is a special amphibious tank and was once an important force across the strait. As time goes by, this tank has become older and needs improvement.
The newly improved tank is 63A, which uses the original number and only adds an A suffix. This tank uses a 105mm tank gun. In recent years, another modern improvement has been made, called 03
Amphibious tank.
As an amphibious and land tank, the weight should not be too large, otherwise it will not float on the water. Therefore, this tank gun also needs to reduce the recoil. Otherwise, fire on the water surface, and the tank will be lifted by the recoil.
After turning over, this is absolutely not possible. Therefore, experts from the Second Machine Factory have adopted the method of extending the recoil distance and introducing efficient muzzle retractors to reduce the recoil of this tank gun by nearly 40%, while maintaining the
The same tank gun performance.
After hearing Nie Jianqiang's introduction, Qin Zhenhua asked: "Is this the only one? Are there any other improvements in the country?"
Hearing Qin Zhenhua's question, Nie Jianqiang thought carefully, and then said: "There is also a 105mm wheeled assault gun in China. Although this kind of artillery is also a 105mm tank gun, it is actually our 100mm
The smoothbore gun billet expanded its inner diameter and processed a 105mm bore structure. That gun was designed to meet the needs of low cost and its performance was even worse."
After saying that, Nie Jianqiang asked Qin Zhenhua strangely: "Director Qin, why have he been holding a 105mm tank gun? Could it be that we have a new tank project? Or is it a light tank?"
If it is a main battle tank, it will definitely not use a 105mm tank gun! Qin Zhenhua chased this gun and asked for high-performance, so he could only want to build a new light tank.
Hearing Nie Jianqiang's words, Qin Zhenhua nodded: "Yes, we want to develop a new tank, planning to use a 105mm tank gun. This gun has the lighter weight, the better, and the greater the power, the better. A hard indicator is that it needs
Let it have the ability to destroy the front main armor of the T-90S at a distance of two thousand meters, that is, the penetration depth of more than 550 mm. If it can reach the penetration depth of 600 mm, that would be even better."
The T-90S looks very powerful, but in fact, the equivalent protection ability on the front is this order of magnitude. Therefore, even if you use a 105mm tank gun, you can penetrate it from the front.
The more powerful 125mm tank gun is not used at all. It is enough to use this 105mm tank gun against the neighboring T-90S. Of course, this pressure will be transferred to the second machine factory.
"Director Qin, if we simply demand this power, we can do it, but if we require light weight, it is really a challenge." Nie Jianqiang said: "However, since it is to fight against the T-90S, then we
The second machine factory must complete this task!"
When Qin Zhenhua said the T-90S, Nie Jianqiang already understood.
