How much power does the Rock 150 engine have?

With a horsepower output of 3,000 horsepower, it can fully drive a weight of 300 tons.

Moreover, if the power of the Rock 150 is insufficient, you can also use the stronger Rock 500!

The Panshi 500 engine has a full 10,000 horsepower! What kind of tank can't be towed? 500 tons can be easily towed. At least 50 km/h.

The key is the track.

It must be very wide, very strong tracks.

This problem was also solved by Wang Buan.

The quality of the crawler forged by 50 billion tons of hydraulic press can be imagined. 120-mm armor-piercing shells are absolutely indestructible.

Bearing a weight of several hundred tons is not a problem at all!

With these supports, there will be no problems at all with the installation of 255-mm heavy guns.

Well, the manufacturing process of the artillery itself......

The larger the caliber of the gun, the more difficult the manufacturing process of the barrel became.

At present, the high-end manufacturing technology of gun barrel is mainly electroslag remelting and self-tightening technology of body barrel. Huaxia has completely mastered these.

However, the static influence of the barrel itself is always a big problem.

The longer the barrel and the greater the weight, the more serious the problem of natural sagging.

Unless there are very high-end raw materials. The barrel can be made very strong and relatively lightweight.

When the gun is fired, the temperature of the barrel chamber may exceed 3000 degrees. Some special shells may even have terrifying temperatures of more than 4000 degrees. Extreme heat can not only severely ablate the barrel, but may also cause the barrel to deform. The life of the barrel will also be significantly shortened. The normal data is only about 1,000 rounds.

In addition, when the shell is fired, the pressure inside the barrel will also exceed 800 megapascals. This is a very scary statistic. If you're not careful, you'll blow up.

At present, there are so many countries in the world that can produce large-caliber gun barrels of more than 100 mm, in fact, there are less than ten. Including one of our neighbors to the east, the development of artillery manufacturing processes was severely limited by the laws of the defeated countries. It also did not have the technology to produce large-caliber barrels. Only rely on imports.

"255 mm caliber ......" Zhong Hui silently calculated.

The temperature in the chamber is at least 4000 degrees Celsius.

The chamber pressure is at least 1200 MPa or more.

This is not a simple statistic.

That's a terrible statistic.

If the quality of the barrel does not meet the standard requirements, it will explode at any time.

The problem is that the current manufacturing process is indeed difficult to create a super gun with a caliber of 255 mm. Unless the caliber ratio is reduced. Reduced to less than 35 times the caliber.

It seems that the previously mentioned US imperialist M-1 240mm howitzer has only 34 times the caliber. The firing range is only a meagre 23 km.

Why is the range so close?

The main thing is that the caliber ratio is too small, which leads to a serious lack of firing range.

Why is the caliber ratio small?

Because of the excess of a certain proportion, the phenomenon of barrel sagging is serious.

Modern 120 mm, 150 mm caliber guns, casually have a range of more than 30 kilometers. More than 40 kilometers is a common occurrence.

Isn't it a shame that you have a 240 mm heavy gun with a range of only 23 km?

That is, the other side of the strait will do such a big wrong.

If you change it a little more savvy, you know that this 240-mm heavy gun is a knockout product.

At present, the star artillery exported by Huaxia is none other than the PLZ45 self-propelled gun. It's just popular all over the world! The major local tyrants have snapped up buying it. It's all dozens of sets and dozens of sets to buy.

Caliber 155 mm, total weight 33 tons, 45 times caliber, maximum firing range 40 km, 360 degrees without dead angle shooting.

It's cheap, it's easy to use, it's sturdy, and it's not perfect.

If you want to talk about the only drawback, I'm afraid that the range is a little short......

It has only 45 times the caliber.

If it can be increased to 50 times the caliber, it will be perfect.

In this way, the firing range will definitely be more than 45 km. The competitiveness in the international market will be stronger. 100% invincible opponents all over the world.

However, if the caliber is more than 50 times, the manufacturing process needs to be upgraded by one level.

After all, the longer the barrel, the higher the requirements for the quality of the alloy.

50 times the caliber, can Wang Bu'an do it?

Absolutely.

Grade 5 high-temperature corrosion-resistant alloys are perfectly fine.

At present, the grade of high-temperature corrosion-resistant alloys is grade four. It can already withstand the high temperature of 15,000 degrees.

If it is raised to the fifth level, it can withstand the high temperature of about 30,000 degrees.

Obviously, it is impossible for the temperature of the gun chamber to reach more than 10,000 degrees.

However, it also needs to be commensurately strong.

After all, it needs to withstand more than 1,200 megapascals.

The fifth-grade high-temperature corrosion-resistant alloy can fully withstand the pressure of tens of thousands of megapascals. It is a trivial matter to make a cannon barrel.

Don't say it's 50 times the caliber, even 100 times the caliber is acceptable.

And the life of the barrel will also reach more than 100,000 rounds.

That is, you shoot desperately, shoot desperately, shoot for decades and it's fine.

In the end, most likely you go bankrupt first.

After all, shells are also expensive.

The most common 155-mm shell costs 20,000 or 30,000 yuan, or about $4,000. ”

(It's expensive, it's scary...... I can't even afford shells without money...... ）

If it's a high-explosive bomb, it can cost $30,000.

If it is a high-precision manufactured shell, the price can be $80,000.

Even if you fire 100,000 rounds of ordinary 155-mm artillery shells, that's $400 million. Absolutely bankrupt.

"Day, arms are really profitable!"

"Paralyzed, no wonder the arms giants are so rich. ”

Wang Buan sighed with emotion.

If there is a chance, Lao Tzu will also intervene.

Thunderstorms, umbrellas, cobras, etc., you don't need to sell any other weapons, just selling shells can make a fortune.

The M1777 light howitzers they sold to India are expensive, and the shells are also expensive, so it is simply not too easy to make money.

In particular, it is necessary to mention guided artillery shells.

As the name suggests, it is an artillery shell with a guidance system installed. The accuracy is very high.

At present, there are only two mature products in the world.

One is an American-made copper spotted snake.

One is the Russian-made red earth.

In 1992, the red soil was made public for the first time, which immediately attracted the attention of many countries, and many countries successively introduced it, among which Sange introduced 10,000 pieces at a unit price of 40,000 US dollars.

The unit price is $40,000!

I also bought 10,000 pieces at a time!

This kind of arms consumables is simply not too refreshing! Money comes faster than money printing machines!

If a war really starts, how long can the 10,000 shells last? At most, all the shells will be used up in half a month. The more intense the battle, the faster the shells will be consumed.

What should I do when I'm done?Buy, buy, buy!

Where to buy from?

That's the crux of the matter.

Where to buy from?

Should Tyrannosaurus Rex Industries get a kick in it?

Should White Feather Whale Technology be plugged in?

Upgrade!

Upgrade!

Upgrade!

All items that can be upgraded, all upgraded!

Upgrade your hydraulic press manufacturing center!

Upgrade the lithography machine manufacturing center!

In the former, the efficiency of the hydraulic press produced will be increased to 1 million tons. More ability to work.

The latter, the resulting lithography machine, will have an accuracy of about 1 nanometer.

The hydraulic press in Yucheng Industrial Park has also been upgraded. Upgrade to Level 5 to reach the 200 million ton level.

In one go, the number of faith points was squandered until there were only a few hundred thousand left, and nothing could be done. Looking back, it looks like a whole new one.

Most of the raw materials have been upgraded to the fifth level.

Production doubled again.

"Boss. ”

"What?"

Shangguan Yuqiang handed over a document.

But it's a business letter.

Vulcan Heavy Industries sent.

Vulcan Heavy Industries is the most important artillery R&D and production group in China, and the aforementioned PLZ45 self-propelled howitzer is their masterpiece.

The content of the business letter is that it wants to jointly develop a high-caliber ratio gun barrel with White Feather Whale Technology.

The so-called high caliber ratio is more than 50 times the caliber.

"I have a say in this issue. Peng Deming's voice suddenly came.

"You're back?" Wang Buan said unexpectedly.

"It's back. ”

"How's it going?"

"The second millennium. ”

"Huh?"

Wang Buan frowned.

Why is it second again?

It stands to reason that the diesel engine he has modified has made up for the shortcomings of the 96B tank! There must be no problem with the power system!

If you compete with the opponent's T72 tank, there is no reason for the 96B to fail!

"If someone else is a landlord, he must take the first place. ”

"Oh. I see. ”

Wang Buyan understood.

Dare is not a technical reason. It's political reasons.

Think about it too. Others are landlords, organizers, and inviters. If you slap your face too hard, others will feel shameless. Influence strategic cooperation.

Therefore, the final result is that with a slight disadvantage of 0.5 points, "relegated" to the second place.

But the Huaxia side is already very satisfied. The participating teams triumphed.

It is estimated that the organizers are feeling depressed.

Perhaps, in the next competition, they will go out T90.

Otherwise, if the T72 continues to be dispatched, it will not be an opponent of the 96B. It will definitely be tortured and killed.

"What do you want to say?"

"About the caliber ratio. ”

"Okay. You say. ”

"Come, let's go in and talk. It's hot outside. ”

"Good. ”

The group entered the conference room.

The air conditioner was turned on, and sure enough, it felt much better.

The people present, except for Peng Deming, who is not afraid of the heat, everyone else can't stand it.

Now is the time when the autumn tigers are raging, and it feels worse than the scorching heat. It was stuffy and hot, and sweat was pouring rain. On Shangguan Yuqiang's body, sweat stains can already be clearly seen.

In order not to give Wang Buan, a pervert, a pervert, and a pervert, a chance to hurt herself, she has always dressed very conservatively.

It means very conservative, that is, it is very thick, very tight, and naturally hot.

Wang Buan had already seen it. Deliberately not to say.

You brought it on yourself. What does it have to do with me?

I, Wang Buan, have long since reformed myself. But if you don't believe me, what can I do?

Peng Deming brought out the whiteboard and explained on the spot.

There are many caliber ratios of the barrel, from 10 times, 15 times, 20 times, 25 times, 30 times, 35 times, all the way to 40 times, 45 times, 50 times......

At some stage of development, there are 55 times, 60 times, 75 times, 88 times, 100 times and so on.

The current trend is to reduce the caliber and reduce the weight of the shells, but the caliber ratio is increased, and the barrel is longer and longer, so as to increase the range.

At present, the largest caliber artillery is basically about 150-155 mm.

Larger calibers, almost all canceled.

Why?

Not necessarily.
