Chapter 525: Siege hammer

"too fast……"
"That's too late……"
"Yes! It would be nice if it was a little later."
"Pity……"
Someone beside Wang Buyan sighed in a low voice.
They are Guan Hongru, Chen Xiangmin and others. They are also here to join in the fun.
After all, the launch of Xuelong 2 is also a gratifying thing. This marks that China finally has a professional polar scientific research ship.
The previous Xuelong, strictly speaking, was not a professional polar scientific research ship.
Its original design was only a polar transport ship.
The transport ship and the scientific research ship are obviously quite surprised. The degree of specialization is seriously insufficient.
Otherwise, a few years ago, it would not be in trouble, and finally the US "Polaris" would be needed to rescue. Every time this matter is mentioned, many people are secretly tingling.
Our icebreaker is too backward. Can't compare with others at all. No wonder you will be scorned by others.
Now Xuelong 2 is launched, hoping that the situation will improve.
However, Guan Hongru, Chen Xiangmin and others are very sorry.
Mainly because the Xuelong 2 started too early.
Many new materials are useless.
Many new technologies are useless.
If it is started now, the effect is absolutely different.
At least, the keel will be highly strengthened. Various hard alloys will come in handy.
Not to mention double the strength of the bow. There is definitely an increase of 50%.
Fortunately, the most important power system has improved.
It temporarily modified two Rock 600 engines. The total power is about 60,000 horsepower.
Its displacement is only 14,000 tons, which is about the same tonnage as a domestically produced destroyer.
Obviously, this tonnage is a bit small!
At least, Wang Bu'an felt very small.
Less than 20,000 tons.
It's not even 15,000 tons.
In the ranks of icebreakers all over the world, they are totally out of rank.
You know, for icebreakers, weight is also a very important icebreaking ability.
In many cases, the icebreaker encounters thick and hard ice and cannot rely solely on impact. It needs to bend the bow of the ship to crush and fracture the ice, and then continue to hit.
Obviously, in this case, the weight of the icebreaker itself is the bigger the better.
The heavier the weight, the thicker the ice that can be crushed.
Mount Tarzan is overwhelming.
The momentum is like a broken bamboo.
That's what I mean.
The largest icebreaker in the world at present should be Russia’s "50 Years of Victory". The displacement is 25,000 tons. Nuclear power. The total power is 75,000 horsepower.
In front of it, the Xuelong 2's 14,000 tons of displacement is indeed a bit hard to handle.
The tonnage is quite different.
The power varies several times.
Especially the power is too far apart.
The fact is that the original design of Xuelong II has an engine power of only 15,000 KW, which is about 20,000 horsepower. Relatively speaking, it is very weak.
Its original design speed was 12-15 knots. The continuous icebreaking capacity is about 1.5 meters.
In addition to nuclear power, the largest conventionally powered icebreaker is the US "Polaris". The same is about 75,000 horsepower.
It is equipped with three gas turbines, each with a maximum power of 25,000 horsepower.
It is by relying on strong power that its icebreaking ability is very strong.
It can be inferred from this that without the power of more than 50,000 horsepower, it simply cannot be among the best.
Fortunately, the emergence of the Rock 600 engine decisively changed this status quo.
The engine power has been doubled to 60,000 horsepower, and the speed is naturally greatly improved. There is no problem with a maximum speed of 40 knots.
Due to the increased engine power, the ice-breaking capacity has also been improved. The continuous ice-breaking capacity reached about two meters.
If the method of reverse collision is adopted, the icebreaking capacity will reach more than three meters.
"Design is inherently insufficient..."
"I couldn't think of it then!"
"Yes! It was totally unexpected at the time!"
"If the Tyrannosaurus rex industry had appeared earlier, it would not be what it is now."
Everyone sighed secretly.
Wang Bu'an appeared too late.
Tyrannosaurus rex industry also appeared too late.
As a result, Xuelong II missed many opportunities for improvement. There is no way to make up now.
Forcibly refitting the Rock 600 power system has already made Xuelong II a bit nondescript. If you continue to modify, I am afraid it will be completely different.
Rather than redesigning and repairing, it is better to redesign and re-produce to produce Xuelong No. 3 and No. 4...
Anyway, what we have now is funds. Some are technology. Some are raw materials.
Even if you want to produce Xuelong No. 5 and No. 6, there is no problem.
Where is the deficiency of Xuelong 2?
The most important thing is that the steel plate of the bow is not strong enough.
It adopts a satisfactory design, and the thickness of the bow steel plate is 50 mm.
In general icebreakers, the ship’s capital is the strongest. All alloy steels with the highest hardness are used. For example, tungsten steel used to make armor-piercing warheads.
50mm thick tungsten steel can successfully crash into two meters thick ice. But that's it.
If you want to increase the thickness of the ice, you have to increase the thickness of the steel plate.
However, the increase in the thickness of the steel plate will result in a sharp increase in the quality of the entire ship.
If tungsten steel increases by 50 millimeters, the mass of the entire ship will increase by about 3,000 tons. Obviously, this is a big test for the engine.
If there is not enough power, the icebreaking ability cannot be improved. The two are contradictory.
The final balance result is that the thickness of tungsten steel is 50 mm.
In addition, the cost of tungsten steel is also high.
Three thousand tons of tungsten steel is worth more than 200 million! Can't afford it.
"Wang Bu'an, if it is for you to design, how thick steel plate are you going to make?" Pang Xihua asked thoughtfully.
"The tank is as thick as it is." Wang Bu'an replied casually.
"Three hundred millimeters?" Pang Xihua smacked.
"Yes! Three hundred millimeters!" Wang Bu'an nodded.
Pang Xihua shook his head slowly.
This Wang Bu'an is crazy.
A 300mm bow steel plate? Just kidding...how much weight does this have?
I am afraid that the tungsten steel itself is more than 20,000 tons.
What is the displacement of the entire icebreaker? 50,000 tons? 100,000 tons?
How big an engine does that need?
One hundred thousand horsepower?
Two hundred thousand horsepower?
400,000 horsepower?
Does he have such ability... No! Wang Bu'an has it!
The latest model of the Rock 700 engine has a single power exceeding 136,000 horsepower. If the four units are combined, it is 550,000 horsepower!
Five hundred and fifty thousand horsepower!
A full 550,000 horsepower!
It is almost equivalent to the nuclear power of two Ford aircraft carriers.
If it is installed on a 100,000-ton icebreaker, it is simply not too crazy. With a 300mm steel plate, I am afraid that ten meters thick ice can be broken.
"In fact, I think 300 millimeters may not be enough." Wang Buan said slowly.
"What? Do you want to increase?" Pang Xihua was shocked again.
Chen Xiangmin's eyes sparkled.
In Ding Yewei's eyes, there were only countless stars shining.
Is the thickness of 300 mm steel plate not enough?
More?
How much to increase?
"Five hundred millimeters." Wang Bu'an said in a deep voice.
"Huh!" Pang Xihua took a breath.
Five hundred millimeters of bow steel plate!
God!
Is this an icebreaker?
This is a battleship!
Do not!
no!
The battleship does not have such a thick bow steel plate!
Where is the thickest part of the battleship steel plate? It is each turret. The thickness of the steel plate of the hull itself is usually about 100 mm.
Moreover, this steel plate is not tungsten steel with extremely high hardness and density!
The weight of tungsten steel is very abnormal.
Tungsten steel with a thickness of 500 millimeters weighs at least 30,000 tons.
In other words, it is this icebreaker, nothing else. The weight of tungsten steel alone is 30,000 tons.
Then, add other parts. Ship sides on both sides. And the stern. The total weight of tungsten steel may exceed 50,000 tons. In this way, what is the total displacement? Is 100,000 tons enough?
"Of course, for the time being, three hundred millimeters is enough." Wang Bu'an turned around, "We are not very demanding."
"Ahem, ahem, not demanding..." Pang Xihua was almost choked.
Three hundred millimeters of tungsten steel also said that the requirements are not high.
The designer of Xuelong 2 is going to vomit blood on the spot!
"Good! Good! Good!" Ding Yewei was full of excitement and couldn't help applauding.
"Very good." Chen Xiangmin also looked forward to it very much.
As long as Wang Buyan has this mind, 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 to ~EbookFREE.me~, the thickness of the tungsten steel in the bow can really reach 300mm. A few meters of hard ice, in front of it, is as fragile as tofu.
The 550,000-horsepower power system pushed the 100,000-ton icebreaker to a speed of 40 knots, and then struggling to crash...
I am afraid it is a big iceberg, which will be violently knocked away by it.
The old Titanic hit an iceberg, but the iceberg was fine, and the Titanic sank.
If it were the icebreaker designed by Wang Bu'an, it is estimated that the iceberg would be crushed.
Three hundred millimeters of tungsten steel! A speed of 40 knots!
No less powerful than an armor-piercing bullet!
If it is 500mm tungsten steel...
No, wrong, not tungsten steel. It is grade six hard alloy.
Its hardness is much stronger than tungsten steel.
The five-hundred-millimeter-thick six-grade hard alloy can completely crush 20 meters of ice.
If the method of heavy pressure and collision is adopted, the ice layer 30 meters thick can be crushed. This ice-breaking ability is definitely the first gear in the first gear.
When necessary, grade 6 hard alloy can also be upgraded to grade 7 hard alloy. Continue to increase the hardness.
Grade 7 cemented carbide should be able to deal with ice layers up to fifty meters thick.
Wang Bu'an's design is very simple and rude.
He gave a name to the icebreaker in his design, called the "siege hammer".
What do you mean?
Just bang.
Regardless of three or seven twenty one, going up is just bumping.
If you don't hit it once, then back up and hit the second time. the third time. the fourth time. Until the ice is broken.
That's right, it's so rude.
Is there any other higher way? It may be.
But Wang Buan was too lazy to think.
Simple and rude is the best.
