Chapter 232 Interlayer Cooling of Naval Gun Barrel Tube
As soon as this conversation came out, not to mention the leaders of the navy present, even the leaders of the army and air force were a little stunned.

The caliber of 76mm is already considered a relatively large one in the medium caliber.

When each shell of this type of artillery is fired, it will generate extremely high temperature and high pressure on the barrel, causing the barrel to completely die out in the continuous superimposed changes.

This process is very short, usually around [-] rounds.

Because of this, no matter whether it is Haiju, Air Force or Army, the artillery they belong to is counted as one, and they dare not spray it to death.

No way, it was so cool to spray wildly at the time, and the cost of damage to the gun barrel afterwards was comparable to a large crematorium, and it was really more uncomfortable than death.

Of course, the army is still good for the air force. After all, the field artillery they belong to does not have the urgent task of air defense, so there is no need to emphasize high rate of fire.

But not the Navy.

Especially in naval battles under modern high-tech conditions where air dominance equals sea dominance, air targets must use all their strength, not to mention medium-caliber artillery, even large-caliber artillery over 100mm must be sprayed at the sky as they can. .

In order to form a dense barrage, the incoming air targets will be shielded from the barrage.

This is not something that naval expert thought up by patting his head, but a real tactic summed up by the lessons learned with blood in several naval battles since World War II.

Especially in the Naval Battle of the Malvinas Islands two years ago, Argentina's Exocet missile sent the British Sheffield into the soul and directly shocked the world.

It is also because of this that in a short window period, it is a seemingly stupid but very effective coping method to vent out as much as possible the shit that is going to the sky.

And this is why, after the end of the Malvinas Islands naval battle, there was a wave of rapid-fire naval gun replacement worldwide.

Of course, the domestic navy has noticed this, and also wants to carry out a comprehensive update of its old naval guns inherited from the Soviet Union in the 50s under this trend.

However, the cooling technology of the gun barrel has not been solved for a long time.

You must know that if high-speed naval guns, especially medium and large-caliber high-speed naval guns, do not have an effective barrel cooling system, the entire barrel will have to be scrapped after a few shots.

This is very detrimental to the continuous combat capability of the ship and the supply of the rear.

It is not that there is no accumulation in this area in China, but the old technology of the Soviet Union in the 50s is still used, that is, a water-cooled casing is installed on the outside of the barrel.

Its principle is very similar to the Maxim water-cooled heavy machine gun during World War I.

The problem is that this cooling method is still effective for small-caliber naval guns, but the barrel cooling effect of medium and large-caliber naval guns is not obvious.

Not only that, because the water-cooled casing needs a certain standard amount to cool the gun barrel, so the general casing is very heavy, which leads to a serious excess of the total weight of the corresponding naval gun.

In the early 80s, a research institute trial-produced a 100mm single-tube naval gun with a total weight of more than 32 tons, which was more than double that of similar foreign products.

Whether it is fitting or maintainability, it is outrageous.

In contrast, the DPZ-076 76mm naval gun of Zhujiang Factory has a round turret that is simple and neat, and a slender barrel that is clean and neat. From the outside, there is no cooling system at all.

But if there is no cooling system, the DPZ-076 76mm naval gun was poured for 5 minutes just now, and it was placed on other guns, and the barrel would have exploded due to the overheating of the barrel, but the DPZ-076 76mm naval gun is still intact. Is it air cooling?

It's impossible, natural air cooling can't suppress the high temperature and pressure that can tear ordinary steel.

Someone asked if they didn't understand, so a leader from the navy pointed to the DPZ-076 76mm naval gun that had stopped firing and asked, "What is the cooling method of your gun?"

"Oh, we are using a brand new cooling method, we call it interlayer cooling of the gun barrel!" Wen Dawei quickly replied.

"The interlayer cooling of the gun barrel?" The leader from the navy couldn't help frowning when he heard this, and then looked at the other naval leaders with puzzled eyes, as if saying, do you know this cooling method?

The other naval leaders were also very at a loss, because it was the first time they had heard of this cooling method, so another naval leader asked: "This is the first time I have heard of this cooling method. It is used in foreign naval gun barrels. Is it based on the improvement of the cooling method?"

"Although we have conducted research on several foreign cooling methods, to be honest, the disadvantages of their cooling methods are still too obvious and do not meet our small and refined requirements, so we simply figured out a new cooling method by ourselves. Way……"

Wen Dawei spoke very calmly, as if all this was taken for granted, but when he heard this, his eyes widened, and he thought that your brat was talking too much.

What does it mean that the disadvantages of foreign cooling methods are too obvious?

Obviously, it also represents the world's advanced level, and it is obvious that others will not give you the core technology. Is the interlayer cooling of the gun barrel of your Zhujiang factory stronger than the results of foreign countries after more than 20 years of exploration and summarization?
What's more, the barrel cooling can be done casually?

Without counting on your fingers, there are several companies in the world that can develop and produce modern naval guns, such as the United States, the Soviet Union, the United Kingdom, France, Italy... gone...

There are only five if it is full of guns. If you leave the United Kingdom, which is holding on to the 114mm naval gun, there are only four that can really go sideways in the field of naval guns.

This shows how difficult it is to modernize naval guns, and the key point is the cooling technology of the naval gun barrel.

Not only must it be efficient, but the overall compactness must be good, and the most important thing is that the overall mass should not be too large, so as to exert the greatest combat effectiveness.

Why, Wen Dawei, when your upper lip touches your lower lip and you come up with a new term, you feel that no one is as good as your Zhujiang Factory?
It's too crazy~!

But just when a military leader was slightly slandering Wen Dawei's immodest words, Wen Dawei blurted out more boldly: "And I believe that the advanced level of our original interlayer cooling technology for naval gun barrels can be summed up in one sentence. , even if I disclose the whole set of technology, the developed countries in Europe and the United States will not be able to manufacture it, and it is no exaggeration to say that it is truly the world's leading level!"

As soon as these words came out, even the leader frowned a little. This was no longer crazy, but almost crazy.

You have to know that the leaders of them just came back from Europe not long ago, and the level of technology there is, these leaders know better than anyone else, Wen Dawei actually said that the developed countries in Europe and the United States can't find out the technology?
Many leaders really wanted to go up and touch Wen Dawei's forehead to see if this kid had a fever and was confused, and he even said the wrong thing.

Wen Dawei didn't explain when he saw this, but asked the staff beside him to unload the DPZ-076 76mm naval gun on the fort, and then asked a group of army leaders to look at it.

At first, the group of leaders didn't see anything, until a leader wearing glasses found several precision-machined boring grooves at the end of the gun barrel, and then he suddenly looked at Wen Dawei: "This... this... this craft, how do you do it?" Arrived?"
