Domestic car manufacturing is weak, what does it have to do with our land tanks?

Domestic.

Northern Vehicle Research Institute.

This is one of the important research and development bases for domestic army vehicle technology.

Just looking at the name, it may sound a bit unremarkable and ordinary.

But if you add”Armored Vehicle Test and Inspection Center””、”Special vehicle design base”、”The”First Technology Development Center of Ordnance Industry” is directly affiliated to China Ordnance Industry Group Corporation.

Any nickname is enough to shock any Chinese citizen!

The products developed by the Northern Vehicle Research Institute, from the war years, the classic Type 63 amphibious tanks and Type 64 wheeled armored personnel carriers, have made great contributions to the rise of the nation.

To the current Type 96 main battle tank, and the strongest and most advanced representative of the army-Type 99G main battle tank.

Once the parameters and advanced level are released, they will shock the world powers!

They are all mainly responsible for and involved in the research and development of the Northern Vehicle Research Institute.

At this time, in the No. 6 office of the institute.

The main project of this office is the research and development of tank outer armor.

As we all know, the outer armor design of the tank has developed to this day, and the technology and internal design are also extremely complex.

It is far from the simple armor welded by steel plates like the old tanks.

The third generation of tanks has developed to date.

It already has”full vehicle composite armor”、”Three defense”、””Inner lining” multiple protection design.

The bullet resistance of composite armor has been greatly enhanced compared to traditional steel armor.

Because composite armor can produce multiple protective effects at the moment of ammunition hitting, the application of multiple layers of thin armor plates allows stress waves to reflect back and forth between gaps many times, which can greatly reduce the impact and destructive power of ammunition and perfectly protect the safety of combatants in the tank.

Wang Fengnian, who was sitting in the office, was the director of Office No. 6 and one of the most famous academicians in the field of materials science in China.

He was looking down and carefully studying the latest design drawings of the external armor of the main battle tank.

This was the latest drawing submitted for review by the State Council, and it was handed over to them for research and development and production.

“The multi-layer mechanical design is very reasonable and the structure is much better than the previous generation.……”

“However, this protection index is too abnormal to meet the requirements!!”

“The penetration resistance reaches 900-1000mm, and the burst resistance reaches 1500-1600mm… Where can I find such high-strength composite steel? Why don’t you carry a 155MM howitzer?”

“This is too much to ask!!”

Wang Fengnian complained in his heart.

The penetration resistance of the third-generation main battle tank is still hovering around 700-800 mm, which is already world-class. Except for the two or three major countries, other mainstream countries can’t catch up.

The design and performance indicators of the next generation of tanks must continue to make breakthroughs and strengthen on this basis.���

But this is understandable.

If we don’t strengthen it, it won’t be the style of China. Only when the military strength breaks through, will we be more confident to face the outside world!

But the difficulty of breaking through is not just talk.

You can design in the National Academy. You are all top academicians in the field of military industry. Sometimes the design ideas you come up with are really amazing.

But it’s not the same in the material research and development department.

At present, there have been no significant breakthroughs in materials science in recent decades, and every step is difficult.

Things like aviation t300 carbon fiber and aircraft carrier steel cables are still stuck in production.

In the composite outer armor of the tank, the outer layer is armored steel plate, the middle layer is glass fiber and steel plate, and the inner lining is non-metallic material.

Armored steel is not only extremely hard, but also must have a certain toughness to resist high-speed impact armor-piercing projectiles without breaking and breaking.

At present, special armor steel with carburizing process is difficult to meet the performance indicators on the design drawings.

It’s very difficult!

Very difficult!!

“Xiao Liu, come in and call me later. I want to give those old guys a good scolding.……”

Wang Fengnian threw the design drawings on the table.

Liu Changming, a researcher outside, hurried in.

Seeing his director’s expression, he was also at a loss whether to laugh or cry, and he cooperated with him carefully.

“Director, what’s wrong with you?……”

“Calm down first. No matter what, you don’t need to scold me. Besides, if you really want to scold me, you need me to call you, but I don’t have the courage to do that.”

While saying this, he took the design drawing. This is important confidential material and cannot be lost.

“What else can I do? Look at the indicators and requirements they put forward. Is this how people work?”

Wang Fengnian blew his beard and glared.

He looked like an old man who was about to roll up his sleeves and fight someone.

“How can the outer armor be so strong? Anyway, I can’t make it. Either let them change the design, or… let them find the materials.”

Seeing the data indicators above,

Liu Changming’s heart also jumped, knowing the difficulty.

But such a requirement is obviously not decided by one or two people.

According to some confidential information, the new M1 tank in the United States seems to have made a great breakthrough, and the top is also under pressure to seek a breakthrough.

Liu Changming smiled bitterly and said:

“Director, you are joking again. All domestic production lines for high-strength composite steel are registered with us. We can’t even find suitable special steel, let alone there.”

The Air Force pursues composite materials that are light, high-strength, resistant to extreme high and low temperatures of radar, and rich in functions.

The Army is different. Marching armored vehicles and armored tanks have a wide range of applications for high-strength steel.

Many production lines of reliable high-end steel materials are developed by their military industry, and then the industrial chain is decentralized to the middle and lower reaches.
