Chapter 527: Propeller cutting ice

Wang Bu'an stood up.
Immediately attracted everyone's attention.
Several foreigners looked at him curiously. There was a little confusion in his eyes.
It seems... Wang Bu'an is angry?
Strange...what reason does he have to be angry?
He looks so young, obviously can't be a big man!
"This is..." McCall asked with squinting eyes.
"This is Wang Bu'an, engineer." Pang Xihua took the initiative to introduce.
"Engineer?" McCall didn't believe it.
"He is an engineer?" Smedley did not believe it either.
"Such a young engineer?" Humphrey also expressed incredible.
Pang Xihua secretly regretted that he had said the wrong thing.
These foreigners will be more real.
In China, engineer may be a respectable name.
However, for these foreigners, the engineers they identify must have qualification certificates.
The differences between Eastern and Western cultures can cause misunderstandings if you are not careful.
Sure enough, all three foreigners misunderstood.
They decided that Wang Bu'an could not be an engineer.
Wang Bu'an is too young to apply for an engineer exam.
Fortunately, Wang Bu'an is already far away.
"I'm leaving first." Pang Xihua hurriedly got away.
"I'm leaving too. See you later." Cui Nianyuan immediately followed.
He also doesn't like dealing with foreigners.
The British are very old-fashioned, but they also have an inherent arrogance.
After all, the former empire that never sets in the sun!
The gap is too big now.
It must be very awkward inside.
People in Kangaroo Country have always had a very serious prejudice against China.
In the international arena, it is this Kangaroo country that always jumps out to fight against China and causes trouble for China. It is very disgusting.
The French are a typical wall grass. I want to maintain a good relationship with Britain and the United States, and I want to benefit from China.
Cui Nianyuan subconsciously felt that there was definitely nothing good to communicate with them.
Wang Bu'an flew away, and he happened to follow.
A group of people came to the power cabin.
It looks a bit awkward. The space is up.
The volume of the two Rock 600 engines is really small. Almost unremarkable!
It turned out to be about to install two gas turbines. The reserved space is very large.
As a result, after the replacement of the Rock 600 engine, even 5% of the original volume may not be available. At first glance, it is indeed very empty. It's totally out of proportion.
The drive shaft is not very big either.
It's not as thick as Wang Buyan's thighs.
The main reason is that the grade 5 hard alloy is hard enough and the diameter does not need to be too large.
Unfortunately, it was built too early. At that time, the six-grade hard alloy had not yet come out. Otherwise, I am afraid that the diameter of the drive shaft will be smaller.
Although the diameter of the drive shaft is not very large, it seems to be a bit thin. However, it can already withstand up to 5 million tons of torque. This is more than enough for Xuelong II, which has a displacement of only 14,000 tons. Even in the worst sea conditions, the two drive shafts will not have any problems.
With twin shafts and double propellers, the speed of Xuelong 2 can be pushed to more than 40 knots.
Wang Bu'an checked the mark on it.
Good guys.
From Guanzhong Industrial Park.
It is the forged product of the 50 billion-ton hydraulic press!
No wonder the diameter is so small. After being squeezed by a 50-billion-ton hydraulic press, how big can it be? How much does it need? 5 million tons of torque is not enough?
"What are these places going to be used for?" Wang Bu'an asked casually.
"We have no arrangements." Cui Nianyuan shook his head.
"Oh."
"The captain decides for himself."
"Also."
Wang Bu'an nodded thoughtfully.
This kind of temporary modification of the power system actually makes the 708 Institute feel uncomfortable.
However, given the outstanding performance of the Rock 600 engine, there is nothing fussy about it. Cui Nianyuan didn't care about these empty places.
Do whatever you like. Anyway, it has no major impact on the overall performance of the icebreaker.
The vacated place may be used to improve the living environment? Reserve more supplies?
In addition to the power compartment, two large fuel tanks were also vacated.
One is the fuel tank of the icebreaker itself. It can load more than 3,000 tons of heavy oil. The space is very large.
One is aviation kerosene used in helicopters. About three hundred tons.
Now, these two places are also vacated.
The Rock 600 engine does not require fuel.
The Tyrannosaurus Rex helicopter carried by the icebreaker does not require aviation kerosene.
In addition, two huge helicopter depots were also vacated. why? Because the quality of the Tyrannosaurus Rex helicopter is very good, there is no need for a hangar at all.
According to Wang Bu'an, the Tyrannosaurus helicopter is very robust and durable. Just park it in the open air.
It is not at all like certain types of helicopters and requires a dedicated hangar.
In the wind, rain, ice and snow, it is safe and sound.
Even if you go to Antarctica, you can still park in the open without worrying about damage.
cold?
Hehe, what is it.
No matter how cold it is, it won't be less than minus 273 degrees.
The Tyrannosaurus Rex helicopter can withstand temperatures of minus 200 degrees. There is certainly no such low temperature in Antarctica.
Combustible hydrogen engines are not afraid of cold at all. The colder the better.
The colder the air, the more moisture.
The more hydrogen is decomposed, the stronger the power.
There is no need to worry about encountering a terrible blizzard. The blizzard was broken up directly.
"Your design is so strange?"
"Why is there so much space left?"
"IMHO, is hydrogen power really reliable?"
"Who designed this?"
Suddenly, the voices of three foreigners came again.
Wang Bu'an sighed secretly, it was really lingering.
I obviously avoided them, but I didn't expect to encounter them here again.
Liang Baimu was also completely helpless.
These foreigners deliberately didn't open which pot to mention which pot.
It feels like they are coming for Wang Bu'an? But on closer look, it doesn’t seem to be the same?
They don't even know who Wang Buyan is.
They don't know much about recent international events.
"Don't bother them." Pang Xihua said.
"Okay." Wang Bu'an nodded.
"Master Wang, the hydrogen power era!" Ding Yewei said with a look of admiration.
"What hydrogen power?"
"It's a combustible hydrogen engine!"
"Ok?"
"The combustible hydrogen engine you invented has brought the world into the era of hydrogen power!"
"Oh."
Wang Buan understood.
Dare to feel that you have been wearing a high hat.
By accident, Wang Bu'an "created" a "brand new" era.
The beginning of the industrial revolution was the era of coal power.
Later, oil was discovered and widely used, so it entered the era of petroleum power.
Subsequently, atomic energy was discovered and used, and entered the age of nuclear power.
Now, combustible hydrogen engines ushered in the era of hydrogen power.
Nuclear power has not yet been widely used. It seems that hydrogen power can be fully promoted.
The sales of Rock series engines are very hot now!
Can be used as mechanical power.
Can be used to generate electricity.
The foundation of industry is power.
Watt invented the steam engine, and the industrial revolution was officially started.
So, Wang Bu'an invented hydrogen power, what changes will happen to industrial manufacturing? In what direction will human society develop?
"Shall we go see the propeller now?"
"Ok."
A group of people came to the stern.
The stern also has a tungsten steel deck. The thickness is also 50 mm.
The design of Xuelong 2 is still very scientific. Taking into account the icebreaking capabilities of the bow and stern. 180 degree rotation of the hull can also be achieved.
If the icebreaking capacity of the bow cannot meet the demand, you can turn around and use the stern.
How to break the ice at the stern? What is special about it?
That is the propeller!
The propeller can cut ice!
Just chip off the ice bit by bit!
Especially when encountering certain raised "ice ridges", traditional ice breaking methods may not be effective.
How to do?
Let the propeller come!
The ice ridge was hollowed out a little bit.
As long as the bottom of the ice ridge is hollowed out. Press harder again. Get it done.
However, it is easier said than done.
There are doorways in it.
It has very high requirements on the propeller.
I want to cut ice!
To cut ice cubes!
Obviously, this is not what an ordinary propeller can do.
Must be specially manufactured propellers.
Look at the logo above.
Obviously there is no problem.
It is also from Guanzhong Industrial Park.
The same is from the forging and extrusion of a 50 billion ton hydraulic press, and the strength is absolutely unremarkable.
What is shaving ice?
Even the granite will be cut off for you!
"let's go."
"let's go."
Soon after, Xuelong 2 started to operate.
It slowly came out of the dock. Start preliminary testing of the power system.
Two Rock 600 engines output power steadily, pushing the propellers to rotate.
The speed of Xuelong II gradually increased.
15 sessions...
20 knots...
25 knots...
30 knots...
The speed gradually stabilized.
Did not hit 40 knots.
Because it has not been completely completed~EbookFREE.me~ I dare not hit the high speed of 40 knots.
Today it was just a simple launch, that is, I went back in a simple circle.
The purpose is to test whether it will sink.
Although the odds are very low, there are.
When a ship was launched into the water, it capsized directly.
Or it sinks slowly.
The real sea trial will not be carried out until all the works are completed.
At that time, you will be able to run farther.
The Jianzhou ship before is a typical example. I ran to the Philippines.
"Buzzing!"
"Buzzing!"
Two Tyrannosaurus helicopters landed slowly.
Xuelong 2 with a displacement of 14,000 tons is equipped with two helicopter platforms.
In Antarctica, if ships are impassable, they must rely on helicopters to travel. One is not enough, it must be two to meet the needs.
If possible, it is best to have three or four. In Antarctica, there are never too many helicopters.
The transportation of materials and personnel to the scientific research station must rely on helicopters.
General small helicopters are completely useless.
The blizzard blew it away.
Previously, the Xuelong was equipped with Ka-32 helicopters. The maximum take-off weight is 14 tons.
The biggest feature of the Ka-32 helicopter is its excellent flight performance, whether it is foggy, cloudy or night, and its safety performance is quite reliable. It is very adaptable to the environment with variable weather and unstable weather. Whether in the Arctic or Antarctic, it is a very popular expedition helicopter.
The price is a bit expensive. Each one needs more than RMB 85 million.
Now, the Ka-32 helicopter has been replaced.
