Chapter 188
For how to proceed next.
The King-Crow group began to get caught up in a heated debate.
Among them, Sun Hongwei, Zhao Zhongyao, and another nuclear physics master, Shi Shiyuan, all put forward their own different views.
Shi Shiyuan joined the Jinwu group at the beginning of last year.
His name is not small.
Because his teacher was the famous Madame Juli.
While studying abroad, he studied with Madame Julie for four years.
When he returned to China in 33 years.
He became a professor and head of the Department of Physics at a domestic university.
Later, after the investigation of the Jinwu team.
He was sucked into the group and became one of the core members of the team.
After Shi Shiyuan joined the Jinwu group, he put forward many constructive ideas.
Especially in the basic theory of nuclear physics, he is even better at.
All three core members have different views on how to purify high-purity uranium-235.
You know, uranium-235 only accounts for 0.7% of natural uranium.
That is, the remaining 99.3% is uranium-238.
All they have to do is separate the 0.7 percent uranium-235 from natural uranium.
So three methods were proposed.
The electromagnetic separation method, gas diffusion method and thermal diffusion method were proposed respectively.
These three methods were also discovered in some top-secret data at the Institute of Nuclear Physics.
The gas diffusion method uses a high-pressure pump to spray uranium hexafluoride gas onto a porous barrier plate.
Light uranium-235 in the gas will pass through faster than heavier uranium-238.
The most important thing about this is the diffuser as a barrier plate.
It takes almost 3,000 repeated separations to obtain uranium-235 with a purity of more than 90%.
And 90% purity is weapons-grade.
It can be used to make mushroom eggs.
This method has also been recognized by many people.
But the cost of this thing is extremely high, and the power consumption is not ordinarily large.
Several large power plants are needed to supply its power needs.
It is a relatively reliable, but extremely expensive method.
The principle of thermal diffusion is relatively simple.
It is isotope separation.
Uranium-238 is separated from it to obtain the desired high-concentration uranium-235.
However, this method has proved to be low in yield and high in power consumption, and has basically been abandoned.
But it is the best way to isolate isotopes.
There is also the most feasible, but at the same time the most expensive way.
This method was proposed by Zhao Zhongyao.
And this method is the electromagnetic separation method.
Know that in the same uniform magnetic field.
The trajectories of charged particles of different masses of isotopes are not the same.
As a result, different isotopes are collected at different locations.
Light isotopes are separated due to their different radii and heavy isotopes of their circular motion.
This is the most basic principle of electromagnetic separation.
The electromagnetic separation method is to collect the required uranium-235 through electromagnetic separation.
The reason is because it costs the most.
This is because at least 5,000 tons of copper are required to build a cyclotron required for electromagnetic separation.
The production of this thing is already very small.
And it is still a strategic material.
This 5,000 tons is just the beginning.
The latter series of work will use at least 100,000 tons.
100,000 tons of copper, which is not a small amount.
In general, all three routes have their own advantages and disadvantages.
But in general, they all have one thing in common.
It consumes electricity and money.
And the money is like a bottomless pit.
You can't hear a single sound at all.
If it were not for Zhang Xueming's strong support for this project.
Then you will definitely get stuck at this level.
After all, except for a very small number of people.
They didn't even know what this Jinwu project was for.
And you don't see any output.
Each of these three routes costs hundreds of millions of RMB.
There are a bunch of factories that need to be built alone.
Therefore, it must be left to Zhang Xueming to choose.
They also wrote separate tirades to prove that their approach worked.
And Zhang Xueming is simply a lot.
"Choose? Why choose? We did not lack this money, and also built a dedicated large-scale power station to generate electricity.
No need to choose, these three routes are carried out at the same time, I approved ~. "
All three routes are full of unknowns.
And he, the crosser, didn't know much about this thing.
So let him choose.
I really don't know which one is the most suitable one.
In case you choose a dead end, or point a crooked tech tree, or choose the most difficult one.
If you choose one path, you may all succeed, or maybe the success rate is only one-third.
Then if he chooses all.
Isn't the success rate 100%?
Mushroom eggs are too important for Huaxia.
Although this will increase costs significantly.
The demands on electricity and resources are particularly high.
If nothing else, let's say more than 100,000 tons of copper, and there are not many people who can take it out to make these things.
But now he doesn't lack these things.
Heard Zhang Xueming's words.
The faces of the three who came to report the work were full of joy.
They did not expect Zhang Xueming's support to be so great.
This unconditional trust also touched them very much.
At the same time, I also feel a lot of pressure on my body.
If their research fails.
Then too many national resources are wasted.
Sun Hongwei nodded solemnly and said, "Thank you Chairman for your support to us."
Even if we don't eat, drink, sleep, or sleep, we will make it. "
Zhang Xueming smiled and waved his hand: "If you say it heavily, you don't need to be too anxious, we still have more time."
Five years, this is the deadline I gave you.
If it can't be done, it doesn't matter, but it must be built within ten years. "
Zhang Xueming's face also became solemn.
Ten years is the worst.
But he thinks that's unlikely.
Nuclear physics laboratories are available through systematic check-in.
The researchers inside are the top of the current era.
Although I dare not say that one can lead a project.
But at least be able to become the elite of this project.
If with their ability, plus their own strong support.
If you can't figure it out in ten years.
That would be ridiculous.
Young Zhao Zhongyao's head shook like a rattle.
"Chairman, it won't take so long.
As long as we have identified the research line, we are confident that it will be built within five years. "
The other two nodded approvingly.
If you take one route.
They may not have such confidence.
But if you take all three routes at the same time.
Absolutely no problem.
Because the purpose of these three routes is the same.
That is to extract uranium-235 with a purity of more than 90%.
This, in turn, will speed up the development of mushroom eggs.
After having their assurances.
Zhang Xueming was also much relieved.
A day later.
A total of six Y-10 strategic transport aircraft landed at the Cold Lake Military Airport.
They came from another nuclear physics institute where the system was checked in.
They were all integrated into the Huaxia Institute of Nuclear Physics.
It is a first-level scientific research institution directly under the Huaxia Scientific Committee.
The Huaxia Scientific Committee is a unit directly under the State Council approved by Zhang Xueming at the beginning of the year.
It is the highest academic institution and scientific research institution in Huaxia.
More than 60 scientific research institutions are included in it.
Unified management.
And not a state of loose sand.
Their arrival.
For the Jinwu plan, it is a powerful new force.
Their leader is a middle-aged woman named Zhu Shuhui.
Don't look at her as a woman, but she has strong expertise in the field of nuclear physics.
And she was also designated by Zhang Xueming as the head of the artificial solar engineering project. (Read violent novels, just go to Feilu Fiction Network!) ）
Except for some personnel who were added to the Jinwu plan.
The rest are focused on nuclear reactors.
Compared to making mushroom eggs.
Reactors are much less difficult.
In a year or two, it is entirely possible to build a usable land pile.
After all, the uranium-235 used in nuclear reactors only needs to be more than 2% and less than 5% pure.
If it is a military ship, the requirements for the nuclear reactor required are higher.
It needs to reach more than 80%.
For nuclear reactors, of course.
Abundances only affect how often nuclear fuel needs to be replaced.
without affecting its power.
The higher the abundance of nuclear fuel, the longer the replacement cycle.
So it's not difficult to build a reactor.
The challenges are miniaturization, security, reliability and stability.
Of course, Zhang Xueming hopes to see the nuclear reactor on board and launched as soon as possible.
But if you want to build a nuclear power plant, you will have to wait at least a year or two.
If you want boat and ship use.
It takes at least five years.
The problem of using nuclear-powered ships in World War II should not be a big problem.
Zhang Xueming stayed in Atomic Town for almost five days.
On the fifth day, they also conducted a second test.
It lasted twice as long as the last time.
"I'm going to hold an air show, which is scheduled for November 1st, which will last for seven days.
If the location is located, it will be in Tianjin. "
Zhang Xueming called Li Tanren over and told him about his own thoughts.
"Airshow?"
After hearing this new term.
Li Tanren was a little confused.
What is this air show?
See this look on his face.
Zhang Xueming smiled lightly and explained: "The air show is also the international aviation exhibition.
It is held for the purpose of which, in addition to showcasing our advanced aviation industry.
We can also promote our foreign trade equipment.
to enhance our international influence.
Air shows can also be held to entertain the public and raise the visibility of air shows. "
After hearing Zhang Xueming's words.
He roughly understood the significance of this so-called air show.
The main purpose is actually to sell things.
"Okay, I'll arrange for someone to set up the project right away and produce the project book as quickly as possible."
Next, Zhang Xueming also explained some details about the air show to him.
Less than two days.
Li Tanren put forward the report.
"Tianjin International Aviation Exhibition Preparation Plan"
Zhang Xueming skimmed through the proposal.
Under his professors.
This air show is already relatively close to a modern full-fledged air show.
No problems were found later.
Zhang Xueming signed his name.
The preparatory group of the first Tianjin International Aviation Exhibition was established.
The venue, the time, the scale of the event, the invitation of aviation companies from various countries, and publicity have all begun to be carried out one after another.
This news also soon spread in the countries of the great powers.
Roosevelt on the other side of the ocean after hearing the news.
There was also a strong interest.
"Aviation exhibition? The Chinese are also going to hold their air shows? "
Airshows are such a thing as air shows that are not new in the West.
The earliest air show was born in Ba Tao, and the time can be pushed back to 1908.
Originally, a corner was opened at the auto show for some aerial aircraft.
Unexpectedly, the unexpected discovery turned out to be very good.
So they held the first Ba Tu Air Show in 1909.
People and aviation companies are very interested in the air show.
It also made the first air show a great success.
The number of visitors reached 100,000.
More than 300 aviation companies participated in the exhibition.
In later generations, this number may not be much.
But in this era, it can be said to be very successful.
So Roosevelt was hearing the news.
will be so interested.
"This may be a good opportunity to understand the strength of the Chinese Air Force."
They will definitely come out with advanced fighters. "
"I see!"
Aviation companies from Germany, Britain, Gallic Chicken, Itoli, Czech Republic, Austria, Bilisi, Sweden and other countries were notified.
They all want to try.
They all called back Tianjin International Airshow Co., Ltd., which was responsible for holding this air show.
Everyone wants to show their products at the air show.
Maybe you can get an order if you are fancy.
For the air forces of various countries, this is also a good opportunity to understand the strength of Huaxia aviation.
This also makes the international popularity of the Tianjin Airshow very high.
The front page headlines in newspapers around the world covered the incident.
To be honest, Zhang Xueming did not expect to release the news just now.
It got such a big response.
Obviously, he underestimated the influence of the Huaxia aviation industry in the current world aviation field.
After all, the fame of the Huaxia Air Force is beaten.
In that case, he should prepare for this air show.
Xifei, Shenfei, COMAC, Chengfei, these domestic aviation bearers have also begun to act.
Began to design special foreign trade models.
Fighters such as the P-51 Mustang and the P-47D Thunderbolt are certainly not for sale.
Although the Huaxia Air Force has begun to equip JF-5 jet fighters in batches.
But these propeller fighters are not far behind.
The technology contained in it is still very high.
In the next few years, it will still be the mainstream active fighter of the Huaxia Air Force.
Even after retirement.
He won't take it out and sell it either.
Instead, choose to seal it.
As a stockpile of armaments for World War II.
In accordance with the document instructions issued by the Office of Military Trade Planning.
The speed of foreign trade fighters must not exceed 600 kilometers per hour.
Instead, the speed should be controlled within 600 km.
As for other indicators, there are no hard and fast rules.
Redesign the fighter in such a short time.
Certainly unrealistic.
But they have ready-made drawings.
These drawings include all models from 45 years ago.
So several companies collegiated.
After all, this cake is so big.
It's better for everyone to work together and eat.
So Shenfei decided to take out the classic P-40 fighter and P-38 Lightning.
Cheng Fei got a piece of the cake of dive bombers.
And dive bombers are definitely the first choice for Stuka.
In addition, the share of the trainer aircraft was also given to Chengfei.
The newly established Chengfei also has to take care of the production of JF-5 jet fighters.
So I can't eat too many orders.
And the western flying side decided to launch a bomber and a transport aircraft.
They are the B25 and C47.
The C-47's fame has already been opened by the C110.
It has always been the star model of Xifei export.
COMAC doesn't need to say more here.
In addition to the C100 and C110, the two hottest airliners sold at this exhibition.
They also decided to launch a small private jet.
With the fire of the world air transport industry.
Demand in the small private jet market is also starting to rise.
For some wealthy people, flying on a passenger plane is uncomfortable, and the time is fixed.
If there is a private jet.
They can go at any time.
And this is also the pioneering work of COMAC's private jet.
