"Xiaoyu, let me introduce you to Uncle Mu. He used to work in the first machine factory. I have seen him many times when I was a child." Qin Zhenhua pointed at Mu Guijin and introduced him to Wang Xiaoyu.
Then, he said to Mu Guijin: "Uncle Mu, you are so naughty. Xiaoyu is my wife who has not passed away. She was scared by you. How do you think you can compensate?"
After Qin Zhenhua said this, Wang Xiaoyu realized that he was joking!
"Is this Xiaoyu? Why didn't you say it earlier?" Mu Guijin's tense face immediately let go, and a smile came out of it: "Xiaoyu, well, it's not bad, she's really beautiful, Old Qin
In the Heavenly Spirit, I will definitely be very happy.”
When he mentioned Qin Zhenhua's father, Mu Guijin's eyes seemed to be a little wet again.
"Uncle Mu, I'm very happy to see you." Wang Xiaoyu reached out to his hand obediently and shook Mu Guijin. Mu Guijin nodded repeatedly: "Since Xiaoyu is here, Uncle Mu will be the host tonight and be in a nearby hotel.
I'm going to treat you to a meal. Xiaoyu, is this your first time in the capital?"
"Cough, cough, Uncle Mu, Xiaoyu is in the capital and has been in college for three years."
Mu Guijin was bored and covered in dust. Everyone laughed loudly. Amid the laughter, Wang Xiaoyu saw a pair of sincere eyes. Those were the kind of care that the elders had for the younger generation.
Wang Xiaoyu was very moved, and the initial slight anxiety completely disappeared.
In China, factories are a very special combination. Sometimes they are merged, sometimes they are separated. Large factories have their own R&D rooms, and some research institutes also have their own production capacity.
In the past few years, the research institutes and factories were separated, but the trend in recent years seems to have begun to merge again.
At the beginning, during the research and development of the second-generation tank, the Tank Design Institute did not compete with the first-machine factory for the design power of the whole machine. This is not because there are a large number of backbone members of the first-machine factory in the design institute and are embarrassed to seize the project.
But because they have higher projects to do.
The director of the design office, Fang Xian, sat in the front position. He greeted Mr. Zhu and sat over. After everyone finished saying hello and sat down, the meeting began.
"We held this meeting mainly for the current progress of various projects." Fang Xian said: "The first problem we need to talk about is the research on the composite armor of the tank. We must work together to solve the problem.
.”
Until now, the most common homogeneous armor is used on the main battle tanks in China. This armor is just a hard steel material. When the 59 tank technology was introduced, it was also established on the grassland market.
A steel group mainly produces special steel for tanks. After several years of research, the steel gradually stabilizes its performance, meeting the tank production needs.
However, the era when tanks use ordinary armored steel is over.
No matter what steel is used, the thickness is limited. If you increase it, there is no possibility of it. For the 59 tank, even if it uses the most streamlined shape and the thickest gun shield, there are only 220 places.
The thickness of millimeters, this thickness, is impossible for modern tank guns to block any barriers.
The tank gun of our own 59 tank can penetrate it after using new ammunition, not to mention the imported L7 tank gun, which often has a depth of more than 300 mm. If it is a larger caliber artillery
, the armor-piercing ability is often above four or five hundred millimeters.
For a long time, tanks faced a reality that the armor was not thick enough. No matter how they increased the inclination angle or changed the appearance, they were very stretched in front of armor-piercing bullets. In other words, tank soldiers were always on the verge of the time they went on.
On the battlefield, they charge forward with the confidence of decisive death.
Continue to increase the thickness? This is unrealistic. After all, the greater the thickness, the greater the weight. After the tank's own weight increases, higher requirements are put forward for the engine and transmission system, and at the same time, it also puts forward for bridges and other things.
Higher requirements.
Since it cannot be increased without limit, armor has always been at a disadvantage in the competition between armor and armor-piercing bombs.
This situation was not until the emergence of composite armor.
If you only increase the thickness, then you should think about changing the structure of the armor! Through different structures, you can provide higher bulletproof performance.
Among them, the most effective one was the results of the Royal Armor Research Institute in the small town of Chobam, England in 1976. They successfully developed a ceramic armor, greatly increasing the protection ability of the tank.
Now, this excellent ceramic armor, named Jobam Armor, has become a trump card of the British Army. Even the United States has imported the technology and is equipped on the United States' own M1 tank.
This kind of key technology is impossible to expect the British to export. If they want to export it, they are definitely low-end goods, and they are not of the same level as their own use. After all, this kind of equipment is the core secret of a country's army.
Therefore, key projects of national defense must be based on self-development.
This is also a key project of the Tank Design Institute.
It is impossible for a machine factory to study these technologies. The machine factory is responsible for the production. Now, the second-generation tank that the machine factory is developing is planned to adopt welding turrets. In addition to increasing the internal space of the turret and moving closer to the west, there are also
Consideration of using composite armor.
Only by welding the turret can composite armor be used. If the turret is cast, it is not convenient to cast complex non-metallic armor into it. At most, it is that when casting, it is doped with a quartz sand interlayer or the like.
The tank prototypes manufactured now can be welded out with ordinary homogeneous steel and then replaced with various technical tests first. However, when it comes to the production stage, it is definitely necessary to develop real composite armor.
Whether it is a second-generation tank, a third-generation tank, or a composite armor, it is a technical difficulty that must be addressed in China. Now, the research and development of these projects of tank design is obviously facing problems.
"Our design institute is conducting the research and development of ceramic composite armor, but we have conducted four years of experiments and have not found a suitable solution." Mu Guijin spoke. After leaving the first machine factory and entering the design institute, he left the design institute.
, and started research and development of this project.
"As for how long it will take in the future, we are not sure, so it is probably impossible to use ceramic composite armor on the second-generation tank."
