Chapter 651 The atomic bomb enters the production stage! (Part 2)
"I come!"
I have to say that the bald man has a really loud voice.
The moment he opened his mouth, he became the most handsome boy in the room, and everyone's eyes were fixed on this shiny bald head almost at the same time.
Several experts who were not paying attention were even frightened, and it took several seconds to recover.
However, these shocked experts did not show any dissatisfaction, but almost smiled and shook their heads at the same time.
The smile is not bitter, but somewhat helpless.
It is clear.
This is not the first time this bald man has done something like this. He probably has such an innate personality.
Zhu Guangya seemed to be used to this person's behavior. Hearing this, he just nodded slightly and asked him:
"Comrade Wu Ke, do you want to lead a team to tackle the problem of honeycomb cardboard partitions for atomic bombs?"
"You have to know that even though the honeycomb cardboard partition is labeled with the word cardboard, it is not an easy thing to tinker with and involves a very complex structural design."
Honeycomb cardboard spacers.
This is a very common paper structure in 2023.
Usually a little larger...for example, a cardboard box for a refrigerator. If you just find an opening and tear it off, the internal structure will be a standard honeycomb cardboard.
Although the honeycomb cardboard partition used in the atomic bomb has the same name, its purpose and structure are obviously not as simple as those of later generations.
The honeycomb cardboard spacer of the atomic bomb is mainly to provide space for the critical collapse of the uranium fuel, so the requirements for this paper core are very special:
Its structure must be easy to break and at the same time have excellent buffering and vibration isolation functions.
That is to say, it won't break no matter how you shake it, but it will make a hole when you poke it with your finger.
Therefore, this is a very technical job, and it will be properly regarded as Party A’s requirement for future generations.
After all, its material is just ordinary cardboard. At most, it can add some other ingredients that can provide auxiliary functions but will not have a decisive impact.
The key to determining whether it can comply with regulations mainly lies in the ability of the developer.
Just like a famous dish called sweet and sour carp in later generations.
The raw materials of this dish are all lively carp, but some chefs make a delicacy that can be called a work of art, and some chefs make a sweet and sour submarine.
Eyes return to reality
Faced with Zhu Guangya's question, the bald man named Wu Ke immediately raised his chest and looked extremely confident:
"Director Zhu, don't worry, I am confident that I can complete the task!"
Seeing this, Xu Yun in the audience quietly turned sideways and asked in a low voice to Lao Guo beside him:
"Guo Gong, I don't know what this comrade's real name is..."
"Oh, you said him."
Upon hearing this, Lao Guo glanced at Wu Ke's bald head and said:
"This is Comrade Wu Xuelin from the No. 1 Branch. He is also one of the first members of the academic department in the country. He is now the deputy director of the Changchun Institute of Optics and Precision Machinery."
"In May this year, we encountered some problems in the finishing of the base, so the organization transferred him from the Northeast to the base."
"He usually has a somewhat rough personality, but he is still very capable in metallurgy, instruments and structures. His team is now also the main force in the metallurgical field of the No. 1 Branch."
Wu Xuelin?
After listening to Lao Guo's introduction, Xu Yun nodded thoughtfully.
It turns out to be this person...
Wu Xuelin, an expert from the capital, is an industrial man who does not have many legendary stories but has devoted his life to the country.
Earlier, like Qian Bingqiong and Yang Chengzong, he was recommended by Yan Jici to study abroad.
Wu Xuelin's majors are mainly mechanical engineering and metal smelting, and he is the first generation of light-chasing people at the Changchun Institute of Optics and Mechanics.
Wu Xuelin is not well-known, but he has made great contributions to China's steel smelting. He is a scholar with both research and development and leadership skills.
At the same time, because he has been in a noisy factory all year round, Wu Xuelin unknowingly spoke with a loud voice.
Another thing that makes Xu Yun feel a little subtle is...
Huang Danian... who later became China's chief expert on gravity gradiometers who died of illness at his workplace, was trained under Wu Xuelin at the university level:
At that time, Wu Xuelin was only two years away from being transferred to the chief engineer of Jinling Astronomical Instrument Factory. In addition to working at Changguang Institute, he also worked as a professor at Changchun Institute of Geology...which later became Changchun University of Science and Technology.
In 1977, Huang Danian happened to be admitted to Wu Xuelin's sect. In this way, two generations of Chinese precision instrument leaders magically became masters and apprentices...
Of course.
Apart from the above, what Xu Yun is most curious about is...
Why is Wu Xuelin bald?
In his impression, although the big boss Wu Xuelin's hair was a little sparse, it was at most alopecia areata...or in the case of the Mediterranean, he still had some hair.
But now Wu Xuelin is a complete idiot, and his forehead is cleaner than the draft box he used to write novels in later generations...
Maybe he guessed what Xu Yun was thinking.
Lao Guo on the side suddenly smiled mysteriously and explained:
"Xiao Xu, do you still remember the air raid siren a few months ago?"
"Air defense alert?"
Xu Yun was stunned for a few seconds, but soon realized what Lao Guo was referring to:
"Oh, you mean the alarm from U2?"
Lao Guo nodded and quickly glanced at Wu Xuelin's forehead:
"That's right, Comrade Xuelin was letting Master Liu from the main factory shave his head in the open space, but the alarm sounded too suddenly. Master Liu was frightened and used too much force..."
"So Comrade Xuelin had to shave his head - but soon he found that the reason for shaving his hair seemed to be better than losing his hair, so he just kept his head bald..."
"Didn't a new group of experts come to the base before? Some of them really believed this rhetoric, so there are a few... well, comrades in the base who are not so prolific and are also thinking about plagiarizing it."
Xu Yun:
"...."
This is what co-authorship is all about...
This chapter is not finished yet, please click on the next page to continue reading the exciting content! The air defense alarm that Lao Guo mentioned was the reconnaissance when the U2 reconnaissance plane passed over the base. That incident was called Xu Yun’s first attempt to integrate into the base.
starting point.
At that time, Xu Yun was still talking about the chaos system with Qian Bingqiong and Ye Duzheng, and was startled by the sound of the alarm.
In this case, it seems reasonable that a certain barber was so frightened that he pushed his head over his head...
Think of this.
Xu Yun temporarily put away his curiosity and glanced at Wu Xuelin again.
Although Wu Xuelin's appearance was an accident, it reminded him of one thing:
Regarding precision instruments...for example, the layout of the gravity gradiometer, I seem to have forgotten to mention it to the writer...
Fortunately, Hawking's invitation letter has not yet been activated. By 2009, I can have a chat with the writer.
There are actually not a few experts like Huang Danian who have accidents due to overwork. They are in situations where the trajectory can be completely changed.
And at the same time Xu Yun's thoughts were diverging.
Zhu Guangya in front of the stage is also continuing his task assignment.
Mentioned earlier.
Zhu Guangya has six main projects to be assigned today. Now that the beryllium/polonium neutron source and honeycomb cardboard spacers have been completed, there are only four left that have not been assigned:
Among them, the U235 fuel layer ball fragment is much simpler. After all, its core is high-abundance enriched uranium.
Now that Yang Chengzong...to be precise, the 504 Factory has completed the refining of enriched uranium, the difficulty of this link has suddenly dropped.
Now its main difficulty lies in the need to produce 32 hexagonal metal blocks of the same size. The parameters of the metal blocks are mainly related to the critical mass.
"... Comrades, according to the design of the theoretical team, the thickness of the fuel layer sphere is 15.4 cm. The uranium block as the target body is placed at the nose cone, so the nose cone is slightly thicker than the side wall by 1.77 cm. In addition,
..."
Zhu Guangya quickly introduced the specific parameters, then looked at Wang Chengshu, the only lesbian in the front row, and asked her:
"Comrade Chengshu, you are an expert in this field, with rich research and development experience, and you are also an old employee of Factory 504. You have worked with Comrade Chengzong for a long time, and your tacit understanding is higher than others."
"So the organization wants to hand over this task to your team. What do you think?"
Wang Chengshu was listening to the introduction attentively. After hearing this, he stood up from his seat neatly, his short and capable hair shaking twice in the air:
"Guaranteed to complete the mission!"
Wang Chengshu had already intended to take over this task when Zhu Guangya was introducing his speech. Now that Zhu Guangya directly called her name, Wang Chengshu naturally had no reason to shirk.
Zhu Guangya also nodded to her.
Seeing this, Xu Yun on the side couldn't help but feel a trace of emotion in his heart.
Later, with the release of the movie "Oppenheimer", Ms. Wu Jianxiong's popularity suddenly increased a lot.
Because many of Ms. Wu Kin-hsiung's contributions were ignored in this film, domestic public opinion, led by certain groups, began to denounce sexism in "Oppenheimer" director Nolan.
At that time, Xu Yun sighed. Fortunately, this movie was made by a foreign director. If it had been a domestic movie, the public opinion would have exploded...
At the same time, in Xu Yun's view.
Ms. Wu Jianxiong's ability is indeed very strong, this is undeniable.
But she changed her nationality very early, the beneficiaries of all her contributions were across the sea, and even the place of death was in New York. Strictly speaking, her contributions had nothing to do with the country.
At least judging from Xu Yun's "shallow and narrow" spiritual realm, compared to Wu Jianxiong, Wang Chengshu is the strange woman who truly deserves to be regarded as an idol in China.
But what's the result?
Oh, just because Wang Chengshu is from China, just because she was not as handsome as Wu Jianxiong when she was young, and just because she later became an academician and was not "suppressed", so she is not counted as "disappeared" by those groups.
Book a special book?
The difference in popularity between the two topics on Weibo alone is 1,734 times. Wu Jianxiong’s science popularization has hundreds of comments, and only two or three likes mentioning Wang Chengshu.
What's the difference between this and the documentary "Shen Jilan" being ignored while "Habi" is being hyped?
At that time, Xu Yun also saw someone under a well-known account that mentioned Wu Jianxiong and asked why he did not talk about academician Wang Chengshu. The blogger was stunned and replied: "Wang Chengshu's mouth is too crooked and does not look good"...
.
How deplorable.
.........
Immediately afterwards.
Zhu Guangya assigned the task of developing the polonium protective layer to an expert whose name Xu Yun had never heard of. This person was called Feng Ji. According to Lao Guo, he was the expert with the deepest research on membrane materials in the base.
That's right, membrane material.
The so-called polonium protective layer is not a metal shell, but a special type of film protective layer - because the main body of the polonium has been isolated by the supporting equipment of the neutron source.
This kind of membrane protective layer can be made from lanthanum chromate perovskite. The difficulty is not low, but the advantage is that the process is very fixed, and it can basically be solved by stacking the amount.
Half an hour later.
Zhu Guangya's eyes suddenly froze as he looked at the audience, and his right hand holding the bamboo pole also exerted some faint force.
Now that the first four tasks have been assigned, today's baton handover meeting has also entered its final stage.
but.....
This stage is not easy.
After all, the remaining plane wave generators and neutron reflection layers are all absolutely difficult to apply.
Even with the various parameters and diagrams calculated by the theory department, they can still be called big bosses.
Zhu Guangya then took a deep breath and pointed the bamboo stick at a structure slightly outside the atomic bomb:
"Comrades, everyone should know that an ordinary bomb explodes from the inside out, and it is a diffuse detonation wave that spreads outward from a single point of detonation."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "However, implosion compression is different. It can detonate through multiple points, causing a spherical wave that converges inward. This focusing effect can make the pressure
Increase the height to improve the compression effect on the compressed object."
"But it requires that all points detonate at the same time, the detonation wave propagation must develop simultaneously, and the spherical waveform must be maintained to propagate and compress inward at all times."
"And if you want to integrate this kind of spherical wave, you must first solve...the plane wave generator."
Synchronize.
This is a very common word in the development process of nuclear weapons.
The so-called synchronization means that each step is consistent in time.
For example, on a playground, many concentric circles are drawn, with each circle one step apart.
There are many students standing evenly on the outer circle, and when given an order, they all march toward the center. Each student must step into the inner circle at the same time with every step.
But the problem is...
For ordinary students who do not have very high military literacy, it is difficult to perform this kind of movement neatly - because everyone's stride may be different.
And if the movement is not neat, the formation lines on the circumference will become zigzag.
The distance between such zigzag shapes is called "waveform difference". The waveform difference can be measured in time, and its meaning is the time difference between each point of the detonation wave front reaching the same radius.
The propagation speed of the detonation wave is known, and the spatial distance difference in the fluctuations of the detonation wave front at a certain moment can be calculated through the time amount of the waveform difference.
For example, if the detonation speed of an explosive is 7,000 per second, and the waveform difference between two points on the wave front is 1 microsecond (one millionth of a second), then the distance difference between the two points on the wave front is 7 microns.
This distance is absolutely not allowed to exist during the detonation process of an atomic bomb, so these waveform differences must be integrated.
As for the integration method...
Naturally, the points are reduced to a plane, and then the plane is exploded.
The speed difference after plane detonation can be optimized according to the detonation speed of the explosive. The specific parameters in this regard have been calculated by >.
But still the same sentence.
The plane wave generator is not a simple module that can be solved with parameters. There may even be some situations in its production process that are larger than can be calculated.
As for the person in charge of this project...who will it be?
Xu Yun also frowned.
The person responsible for this calculation in history was Wang Ganchang, and he was indeed a very suitable candidate.
But the problem is...
Now, under the instigation of Xu Yun's chirping wings, the hydrogen bomb project is expected to proceed simultaneously.
Compared with the atomic bomb, Wang Ganchang can obviously play a stronger role in the hydrogen bomb.
Therefore, if the task of plane wave generator is once handed over to this "king", the possibility of simultaneous development of hydrogen bombs will be very low.
True.
Nuclear weapons are a very collective project, but this does not mean that individual strength can be ignored.
Nowadays, there are almost no domestic substitutes for Wang Ganchang's abilities, so from an inner perspective, Xu Yun does not really want Wang Ganchang to be assigned to the plane wave generator project.
But if it weren’t for Wang Ganchang, then who could take on this important role?
more than the?
Obviously inappropriate.
Yu Da's ability lies mainly in theory, and he is a well-known weak chicken in terms of application.
Lao Guo?
Nope either.
Although Lao Guo is engaged in applications, his direction is mainly in fluids, and there are the same barriers as plane wave generators.
And just when Xu Yun frowned.
Zhu Guangya on the stage suddenly looked in a certain direction and announced a name that Xu Yun had not expected:
"Comrade Qian Wushi, are you willing to accept this task?"
