"Too fast......"

"It's too late......"

"yes, if only it were later. ”

"It's a pity ......"

Around Wang Buan, someone sighed in a low voice.

They are Guan Hongru, Chen Xiangmin and others. They're also here to join in the fun.

After all, the launch of the Snow Dragon 2 is also a gratifying thing. This marks that China finally has a professional polar research ship.

The previous Snow Dragon, strictly speaking, was not a professional polar research ship.

It was originally designed to be a polar transport ship.

The transport ship and the scientific research ship were obviously quite surprised. There is a serious lack of specialization.

Otherwise, a few years ago, it would not have been in trouble, and in the end the American "North Star" would have been needed to come to the rescue. Every time I mention this matter, many people feel a secret sting in their hearts.

Our icebreakers are too far behind. Completely incomparable to others. No wonder they are being despised by others.

Now, the Snow Dragon 2 is in the water, and hopefully the situation will improve.

However, Guan Hongru, Chen Xiangmin and others are very sorry.

The main reason is that the construction of Xuelong 2 started too early.

A lot of new materials are not used.

A lot of new technology is also not used.

If you start work now, the effect will definitely be different.

At the very least, the keel or something will be highly strengthened. A variety of cemented carbides will come in handy.

The strength of the bow, not to mention doubled. A 50% increase is definitely there.

Thankfully, the most important powertrain has improved.

It was temporarily modified with two Rock 600 engines. The total power is about 60,000 horsepower.

It has a displacement of only 14,000 tons, which is about the same tonnage as a large domestic destroyer.

Obviously, this tonnage is a bit small!

At least, Wang Bu'an felt very small.

It's less than 20,000 tons.

Not even fifteen thousand tons.

In the ranks of icebreakers in the world, it is not ranked at all.

You know, for icebreakers, weight is also a very important icebreaking ability.

Many times, when an icebreaker encounters thick ice, it cannot simply rely on impact, but needs to use the method of cocking the bow to crush the ice, fractur, and then continue to impact.

Obviously, in such a situation, the greater the weight of the icebreaker itself, the better.

The greater the weight, the thicker the ice that can be crushed.

Tarzan is at the top.

It's overwhelming.

That's what it means.

The largest icebreaker in the world at the moment should be the Russian "50 Years of Victory". Displacement 25000 tons. Nuclear power. Total power 75000 horsepower.

In front of it, the 14,000-ton displacement of the Snow Dragon 2 is indeed a bit out of reach.

tonnage, a big difference.

power, the difference is several times.

The power, in particular, is simply too far apart.

The fact is that the original design of the Snow Dragon II had an engine power of only 15,000 K, which was about 20,000 horsepower. Relatively speaking, it is very weak.

It was originally designed for a speed of 12-15 knots. The continuous icebreaking capacity is about 1.5 meters.

In addition to nuclear power, the largest conventionally powered icebreaker is the American "Polaris". Again, it's about 75,000 horsepower.

It is equipped with three gas turbines, each with a maximum power of 25,000 hp.

It is by relying on strong power that its ice-breaking ability will be very strong.

It follows from this that without more than 50,000 horsepower, it simply cannot be at the top.

Fortunately, the emergence of the Panshi 600 engine decisively changed this situation.

The engine power has been tripled to 60,000 horsepower, and the speed has naturally been greatly improved. There is no problem with reaching a maximum speed of 40 knots.

The ice-breaking capacity has also been improved due to the increased engine power. The continuous ice-breaking capacity reaches about two meters.

If the method of reversing collision is adopted, the ice-breaking capacity will reach more than three meters.

"Design is congenitally deficient ......"

"I didn't think of it at the time!"

"yes! I didn't think of it at the time!"

"If the Tyrannosaurus Rex industry had appeared earlier, it wouldn't be what it is now. ”

Everyone was secretly emotional.

Wang Bu'an appeared too late.

The Tyrannosaurus rex industry also appeared too late.

As a result, the Snow Dragon II missed a lot of opportunities to improve. There's no way to make up for it now.

Forcibly modifying the Panshi 600 power system has already made the Snow Dragon 2 a bit nondescript. If you continue to refit it, I'm afraid it will be unrecognizable.

Instead of a makeover and tinkering, it is better to redesign, re-produce, and produce the Snow Dragon No. 3 and No. 4......

Anyway, what we have now is money. Some are technology. Some are raw materials.

Even if you want to produce Snow Dragon No. 5 and No. 6, there is no problem.

What are the shortcomings of the Snow Dragon II?

The most important thing is that the steel plate in the bow of the ship is not strong enough.

It has a modest design with a 50 mm thick bow plate.

Icebreakers in general, the capital of the ship is the strongest. All alloy steels are made of the highest hardness. For example, tungsten steel, which is used to make armor-piercing warheads, and the like.

The 50 mm thick tungsten steel can successfully destroy two meters of ice. But that's about it.

If you want to increase the thickness of the icebreaker, you have to increase the thickness of the steel plate.

However, the increase in the thickness of the steel plate will lead to a sharp increase in the mass of the entire ship.

If tungsten steel is increased by 50 mm, the mass of the whole ship will increase by about 3,000 tons. Obviously, this is a big test for the engine.

If you don't have enough power, you won't be able to improve your ice-breaking ability. The two are contradictory.

The final balance result is a tungsten steel thickness of 50 mm.

In addition, the cost of tungsten steel is also high.

3,000 tons of tungsten steel, worth more than 200 million!

"Wang Buan, if you are asked to design, how thick are you going to build?" Pang Xihua asked thoughtfully.

"The tank is as thick as it gets. Wang Buan replied casually.

"Three hundred millimeters?" Pang Xihua smacked.

"Yes, three hundred millimeters!" Wang Buan nodded.

Pang Xihua shook his head slowly.

This Wang Buan is simply crazy.

300 mm bow plate? just kidding...... How much does that have to weigh?

I'm afraid that tungsten steel alone is more than 20,000 tons.

What is the displacement of the entire icebreaker? 50,000 tons, 100,000 tons?

How big of an engine is that?

100,000 horsepower?

Two hundred thousand horsepower?

400,000 horsepower?

Does he have that ability...... No! Wang Bu'an has!

The latest model, the Panshi 700 engine, has a power of more than 136,000 horsepower in a single unit. If the four units are combined, it is 550,000 horsepower!

550,000 horsepower!

That's 550,000 horsepower!

It's almost the equivalent of two USS Ford aircraft carriers.

If it's mounted on a 100,000-ton icebreaker, it's just not too crazy. With a 300-millimeter steel plate, I'm afraid that ten meters of solid ice can be shattered.

"In fact, I don't think 300 millimeters is probably enough. Wang Buan said slowly.

"What? do you want to add?" Pang Xihua was stunned again.

Chen Xiangmin's eyes were shining.

In Ding Yewei's eyes, there are only countless stars shining.

Three hundred millimeters of steel plate thickness is not enough?

And more?

How much?

"Five hundred millimeters. Wang Buan said in a deep voice.

"Whew!" Pang Xihua gasped.

500 mm bow steel plate!

Oh, my God!

Is this an icebreaker?

It's a battleship!

No!

No!

Battleships also did not have such thick bow plates!

Where is the thickest part of the steel plate of the battleship? The thickness of the steel plate of the hull itself is usually about 100 mm.

Moreover, this kind of steel plate is not tungsten steel with extremely high hardness and density!

The weight of tungsten steel is very perverted.

Tungsten steel with a thickness of 500 mm and a weight of at least 30,000 tons.

In other words, it's this icebreaker, and nothing else. The weight of tungsten steel alone is 30,000 tons.

Well, add the other parts. Sides of the ship. And the stern. The weight of tungsten steel will probably exceed 50,000 tons. So, what is the total amount of water displaced? Is 100,000 tons enough?

"Of course, for the time being, three hundred millimeters is enough. Wang Bu'an changed his words, "We don't have high requirements." ”

"Ahem, ahem, it's not demanding......" Pang Xihua almost choked.

300 mm tungsten steel, it is also said that the requirements are not high.

The designer of Snow Dragon 2 is going to vomit blood on the spot!

"Good, good, good!" Ding Yewei's face was full of excitement, and he couldn't help but applaud.

"Good. Chen Xiangmin is also looking forward to it.

As long as Wang Buan has this thought, it is a good thing.

As long as Wang Buan is willing, he can really make a 100,000-ton icebreaker.

As long as Wang Bu'an is willing, the thickness of tungsten steel in the bow of the ship can really reach 300 millimeters. The ice, which is several meters thick, is as fragile as tofu in front of it.

The 550,000-horsepower power system pushes the 100,000-ton icebreaker to a speed of 40 knots, and then crashes into it......

I'm afraid that even a big iceberg will be smashed open by it.

The Titanic in the past hit an iceberg, but the iceberg was fine, and the Titanic sank.

If it is an icebreaker designed by Wang Buan, it is estimated that what will be smashed is an iceberg.

300 millimeters of tungsten steel! 40 knots!

No less powerful than an armor-piercing bullet!

If it is 500 mm tungsten steel......

No, wrong, not tungsten steel. It is a grade 6 cemented carbide.

Its hardness is much stronger than that of tungsten steel.

Grade 6 cemented carbide with a thickness of 500 millimeters can completely shatter a 20-meter-thick layer of ice.

If the method of heavy pressure and collision is adopted, the 30-meter-thick ice layer can be crushed. This ice-breaking ability is definitely the first gear in the first gear.

When necessary, grade 6 carbide can also be upgraded to grade 7 carbide. Continue to increase the hardness.

Grade 7 cemented carbide, which should be able to deal with a fifty-meter-thick layer of ice.

Wang Buan's design is very simple and crude.

He gave the design of the icebreaker a name called the "battering ram".

What do you mean?

It's a slam.

Regardless of three-seven-twenty-one, going up is a collision.

If you can't hit it once, then go back and hit it a second time. The third time. Fourth. Until the ice is broken.

That's right, it's that rough.

Is there any other higher way? There may be.

But Wang Buyan didn't bother to think about it.

Simple and brutal is the best.
