Chapter 591 The last piece of the puzzle of the base... falls into place!
After Yang Wen and Liu Yunquan completed their exchange.
Liu Yunquan began to arrange the delegation...or the personnel of the trade group for Mao Xiong to participate in this exhibition.
Although the task of the entire trade group this time is very arduous, its impact can be said to be extremely far-reaching. I don't know how many people's eyes are locked on Liu Yunquan and the others.
However, due to some well-known special reasons, the political standards of the trade group are not high.
Among the fifteen people accompanying him.
Except for Liu Yunquan, the head of the Maoxiong station who returned to China to report on his work.
The rest are either experienced but low-level external relations officers, or veterans who have participated in foreign trade many times.
Not to mention the big shots, the top three leaders of the department are nowhere to be seen. They are all small cadres at the department level, focusing on a low configuration and high cost performance.
Three days later, the 40 boxes of Coke produced by the Capital Food Factory were officially packaged.
On the morning of the fourth day, fifteen members of the trade group gathered on time at the location of the capital’s external relations department.
Liu Yunquan and Yang Wen verified the identities of the members one by one. After the comrades of the Secrecy Front checked their luggage, the trade group officially set off.
Three hours later, the business group arrived at SJZ Airport and took the waiting special plane to fly to...Moscow.
........
And at the same time as the trade group set off.
Base 221 thousands of kilometers away.
Xu Yunze, Lao Guo, Li Jue, Qian Wushi and others were wearing safety helmets and followed Su Chengye, the head of the base construction industry team, to a remote construction site.
However, despite the fact that this construction site is close to the periphery, its code name is actually quite high. It ranks sixth among the eighteen branches of the factory.
"one......"
"two......"
"three......"
"Four......"
"five......"
Look at the five square buildings in front of you.
Lao Guo, Li Jue and other base leaders who had arrived earlier could not help but express emotion on their faces.
If we push the time forward one and a half months.
Who would have thought at that time that the detonation test site, which seemed to take a long, long time to build, could be completed ahead of schedule a month later?
That's right, the detonation test site.
The reason why all the leaders gathered here today is because the detonation test site that the entire base has been worrying about for a long time has finally been officially completed.
After a while, a young old man in his fifties with a Mediterranean hairstyle walked up to a few people and said:
"Several leaders, it's hot outside, why don't we visit and talk."
Hearing this, Li Jue and Lao Guo looked at each other and made a gesture of invitation:
"No problem, Senior Engineer, please lead the way."
Lao Guo introduced Xu Yun in a low voice while pushing Xu Yun's wheelchair:
"Xiao Han, this comrade is Comrade Gao Yuanming, the general person in charge of this detonation test site. He was officially elected as the director of the Sixth Branch Factory at the previous executive meeting."
Xu Yun nodded clearly.
He was not very familiar with the name Gao Yuanming, but he felt like he had heard it somewhere, but judging from his position, he should be a very capable comrade.
Then, led by Gao Yuanming, a group of people walked into the nearest building.
This building...or the appearance of these five buildings is basically the same. It looks like a small building with one floor high and an area of only 40 square meters.
The only difference between these five buildings is that there are several different numbers marked on the entrances.
For example, the building Xu Yun and the others entered.
There was a circle drawn with red paint at the entrance, and the word [2] was written in the middle, and that was it.
But after entering the building, another scene appeared in front of Xu Yun and others.
The interior of the building is the same as the theory department that Xu Yun went to before. The shell of the building is just a decoration, and the real 'protagonist' is hidden underground:
There is a staircase leading underground inside the small building, and beside the staircase is still a lifting platform for material transportation - as Xu Yun visits more and more places in the base, this configuration will probably not be uncommon in the future.
.
After all, underground facilities are standard equipment for scientific research. Not to mention China, fur bears and those across the sea are not uncommon.
Immediately afterwards, the younger and more powerful leaders walked towards the stairs, while the older seniors and Xu Yun took the lift platform to the next floor.
As a result, I just walked off the platform.
Xu Yun raised his eyebrows.
The theoretical department led by Lu Guangda was also located underground, but compared to the slightly dim lighting effect of the theoretical department, the light in the detonation laboratory was much brighter.
Xu Yun took a closer look, and if nothing unexpected happened, there should be iodine tungsten lamps hanging around.
The light efficiency of iodine tungsten lamps can reach about 30. The interior is filled with iodine vapor, which will combine with tungsten at low temperatures and decompose with tungsten at high temperatures.
Because of this, iodine tungsten lamps are brighter and last longer than ordinary incandescent lamps.
This kind of light intensity is close to the brightness of office buildings in later generations, which is indeed not an easy task in this era.
After all, the iodine tungsten lamp was only invented two years ago. In today's situation of total blockade, it is a real rarity.
This is not to say that there is no such thing in China today, but it is still difficult to assemble such a large array - now domestic iodine tungsten lamps are generally concentrated in large squares in big cities such as the capital and Shanghai, even if they are slightly smaller
You can't even see any provincial capital.
And under the illumination of these powerful lights.
The situation in the basement was also clearly displayed in front of everyone:
There is a large room on the left and right sides of the crowd. The length of a single wall seems to be about ten meters, but the details of the two rooms are slightly different.
The walls of the room on the left are entirely made of refined steel alloy. The thickness is unknown due to sight problems. The single dark metal panel gives off a cold and oppressive feeling under the light.
There is a closed metal door in the middle of the steel wall. The door is about two meters high. It has a single-opening structure and a steering wheel-shaped turntable lock on the left end.
This chapter is not over yet, please click on the next page to continue reading! The wall of the room on the right is mainly made of concrete, with an iron door on the left and right sides as the entrance, which looks a bit low-key.
"Everyone, as you can see, this is the most important No. 2 station of our detonation test site."
Then Gao Yuanming took the initiative to walk up to the crowd, pointed to both sides and said:
"The steel-wrapped room on the left is the experimental site numbered A, which is mainly responsible for cold explosion experiments."
"The one on the right is the data sampling center, whose function is to collect various data immediately after the cold explosion experiment."
"In order to build these two rooms...especially the No. 1 test site, we have invested a lot of manpower and material resources. It is not easy..."
Hear this.
Many leaders at the scene nodded.
Students who have read the book "Into Unscience" should know this.
From a structural point of view.
Atomic bombs are composed of high explosives and nuclear components.
When high-energy explosives explode and compress nuclear components, causing them to fission to produce energy and release it, this is a normal nuclear explosion.
This nuclear explosion process is also called a thermal test.
But for an atomic bomb development project, it is definitely unreasonable to carry out a nuclear explosion without doing anything.
Before the thermal test is carried out, a pre-experiment that does not add nuclear explosive materials and only tests high-energy explosives must be conducted first - after all, it is necessary to test whether parts other than nuclear materials are operating normally.
This kind of experiment is the so-called cold experiment, also known as a 'cold explosion'.
The place where cold explosion experiments are performed is the detonation laboratory.
Therefore, the detonation laboratory can be regarded as the first and last checkpoint in the application field of atomic bombs. Without this test site, the research and development of explosives would be very difficult.
But the detonation laboratory is not as simple as digging a hole. Its design process requires many key parameters.
Base 221 only broke through the design barriers of the detonation laboratory in April this year, then passed the report in mid-May and officially started construction in early June.
But after construction, the base discovered a problem:
Meteorological conditions have a great impact on the construction of the detonation laboratory. Heavy rain will affect the foundation pit, and sand and dust will make the overall structure unable to meet the load requirements.
In the entire month from June to July, the construction team completed less than 20% of the planned plan for that month.
Looking at the entire base at that time, even Lao Guo and Lu Guangda were about to give up.
Thinking of this, everyone's eyes turned to Xu Yun at the same time.
After discovering that meteorological conditions have a great impact on construction efficiency.
The base tried to use manual data collection to conduct meteorological deductions, but the results calculated by Ye Duzheng and others were very different from the actual situation.
But just when everyone thought this project would be delayed indefinitely.
Han Li.
The patient that Lao Guo brought back from Guide County came up with the damper principle and weather Doppler radar technology, and he got out of hand and contributed a lot of new and valuable knowledge and concepts.
Not an exaggeration.
The emergence of Han Li, who is quite mature, has changed the development efficiency of the base in the past two months from approximately equal to double greater than, which instantly improved a lot.
Lao Guo, who was behind Xu Yun, had obviously thought of this as well. He was silent for a moment and patted Xu Yun's shoulder gently:
"Comrade Han Li, thank you for your hard work. On behalf of all the comrades at the base, I would like to express my heartfelt thanks to you!"
Xu Yun turned slightly sideways in his wheelchair, which was regarded as "giving over" to Lao Guo's words.
Just kidding, he really can't stand this.
after all......
The people who can truly claim the words "Thank you for your hard work" should be Lao Guo himself, Li Jue, the factory director, Gao Yuanming, the explosives engineer... and every member of the base except Xu Yun.
right.
Without the hardship they endured, how could Xu Yun enjoy that kind of living and learning environment in future generations?
It was not people of Xu Yun's generation that Lao Guo and others were benevolent to. They had suffered doubly for the billions of people in China.
And what Xu Yun did was just give back a tiny bit of the blessings they would receive from their future generations.
If you have to be rewarded for this, you will be scolded when you go back!
After a while.
Gao Yuanming led everyone to the left...that is, to the entrance of the experimental site. Since he was not young, he asked two stronger young workers to open the turntable.
Crunch——
As the entrance opens, an aisle appears.
Gao Yuanming led everyone through, and after a while, an empty field suddenly appeared in front of everyone.
Judging from visual inspection, the area of the site is about tens of thousands of square meters, and there are some things placed in some areas at different angles and distances:
There were stones, wood, metal plates, and Xu Yun even saw a bicycle...
In addition, there are all kinds of things inlaid around the walls, and some of the walls even have bumpy structures. From the overall high-standard design, it is not difficult to see that this bumpy layout should be deliberate.
"Everyone, this is the actual scene of our experimental site."
After arriving at the scene, Gao Yuanming walked to the front of the crowd, pointed at the wall of the entrance and said:
"This wall is made of high-strength concrete with a thickness of 5.72 meters. The outside is also wrapped with steel plates, which can withstand strong explosion impacts."
"The specifications of the experimental site are a square with an area of 100X100 meters, located 18 meters underground."
"As for these props and walls in the venue, they are used to detect the power of high explosives...that is, the impact of the explosion."
"Explosion force?"
hear the word.
Among the many entourage, a tall but extremely thin man in black couldn't help but adjust his glasses and asked Gao Yuanming:
"Senior Engineer, I have a question to ask - if I remember correctly, the testing of explosive performance is usually done through certain instruments, right?"
"For example, impact sensitivity, thermal sensitivity and other parameters, these instruments should be available in China."
After the tall and thin man said this, several experts present who had some knowledge of explosives also nodded.
Explosives performance testing.
This is a technical discipline that emerged very early, and it is basically synchronized with the modern history of mankind.
Especially after the emergence of various instruments in the early 20th century.
The testing of explosive performance has gradually begun to develop towards precision.
For example, at this time, the performance of explosives mainly focuses on sensitivity measurement.
The so-called sensitivity refers to the difficulty of explosives causing an explosion under external influence, referred to as sensitivity.
There are currently three main types of sensitivity, namely:
mechanical sensitivity,
thermal sensitivity,
Detonation sensitivity.
High explosives in nuclear weapons are military explosives. This type of explosives has lower mechanical sensitivity and thermal sensitivity, but higher detonation sensitivity.
This kind of measurement is mainly based on shock waves, and is restored digitally according to the degree of shock.
Of course, this kind of reduction is also an approximate algorithm in today's era.
Wait a few more decades.
With the development of spectral analysis equipment, high-precision evaluations such as nuclear explosion core temperature and radiation indicators will also appear.
It is true that many precision instruments that are common in later generations have not yet appeared in this period, but some early equipment still exists.
Even if you are currently a poor rabbit, it is not difficult to take out a few measuring instruments.
Facing this question raised by the tall and thin man, Gao Yuanming was silent for a moment, and a wry smile appeared at the corner of his mouth:
"Comrade, if my prediction is correct, you should be engaged in theoretical research, right?"
The tall and thin man nodded and introduced himself:
"That's right, my name is Wang Hua. I graduated from Michigan State University. I am now responsible for solving some data in the fourth group of the Theory Department."
Gao Yuanming nodded clearly and then explained:
"Comrade Wang Hua, you may have less contact with the application field in your daily life, so you subconsciously ignored some subtle details."
"For example...the yield of the explosive we tested."
Wang Hua blinked:
"equivalent?"
"Yeah, equivalent."
Gao Yuanming sighed softly, pointed around and said:
"You are a theoretical person, so you should also know very well that our preset atomic bomb yield has not been finalized, but the value range will not be less than 20,000 tons."
"If we want to create a high-temperature and high-pressure environment to induce uranium-235 nuclear fission to reach this explosive level, we need high-energy explosives...that is, RDX or self-developed explosives with similar performance, which requires at least 10 kilograms of explosives."
"There is a high probability that an explosive impact of this magnitude will exceed the upper limit of the measuring instrument, causing serious damage to the instrument after just a few uses."
"Once we enter the application research and development stage, the detonation laboratory will conduct an experiment once every three days on average. Maybe we can afford the instrument loss for one experiment, but what about ten times? What about twenty times?"
Wang Hua was slightly startled and fell into silence.
He did ignore this...
Opposite him, Gao Yuanming was still shaking his head, took a deep breath, pointed at the nearest target and said:
"So we can only give up instrument measurement and temporarily 'acquire' the bombardment data through some special walls planned during the design of the test site. In addition, we can use these targets with different orientations and distances for analysis."
"We coated the target with some hydrogen sulfide phase liquid. This phase liquid is extremely unstable and will burn quickly after receiving a shock wave."
"When the explosion starts, our operators will hide in the concrete safety room next door and wait. After the explosion ends, they will immediately come to the experimental site to collect these targets."
"Afterwards, by analyzing the combustion situation of the hydrogen sulfide phase liquid and using the multi-target balance error, we can roughly determine the effect of the explosive."
"Hydrogen sulfide?"
Wang Hua, who had just recovered his senses, suddenly shrank his pupils and his tone became a little higher:
"Isn't that thing highly toxic to the human body? And the operator is on standby next door. What if we are affected by the shock wave of the explosive?"
"Comrade Yuan Ming, you are putting the life of comrade operator at risk. This is so unreasonable!"
"Yes, it is unreasonable."
Facing the somewhat angry Wang Hua, Gao Yuanming nodded calmly:
"So the first batch of operators will be taken by myself and my second son. If something happens, just take my life."
As soon as Gao Yuanming finished speaking.
Wang Hua's originally angry expression immediately froze on his face:
"..."
at the same time.
A look of surprise appeared on Xu Yun's face at the same time.
He finally remembered who Gao Yuanming was...
It turns out to be that person?!
Students with good memory should remember it.
When Xu Yun came up with the damper project before, he met a sideline team engineer named Yao Xiaolin next to the tower, who was also the team leader of Zheng Tao and Zhou Shaoping.
At that time, Yao Xiaolin was responsible for the installation of humidity instruments. After learning Yao Xiaolin's name, Xu Yun quickly remembered the other party's deeds:
Yao Xiaolin's father and brother worked as traffic officers behind enemy lines during the Anti-Japanese War in their early years, and died heroically in 1941 and 43 respectively.
Three of his four sons became soldiers. The eldest and the third died heroically in the peninsula battle, leaving their heroic souls on the peninsula forever.
As for the second child, he disappeared while searching for Bosten Lake.
Lao Si and Yao Xiaolin were selected into the sideline construction team of the 221 base at the same time, and later collected data at the No. 3 station of the detonation test site.
in the original history.
Since there is no variable like Xu Yun in the base, a lot of sand and dust were mixed into the entire detonation test site during the construction process, and the load capacity did not meet the design expectations.
As a result, the No. 3 station collapsed after an explosion experiment. Yao Xiaolin and his son, together with three other observers, died heroically at the same time, making the whole family loyal.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! When Xu Yun wrote about this plot in his previous life, many readers expressed their respect in this chapter.
But what few people know is.
Among the other three observers who died, there was also a father and son.
They were Gao Yuanming, the then chief explosives engineer, and his second son Gao Shulin...
Among them, Gao Yuanming was the senior with the highest position at the time of his death in the entire 596 Project.
If Gao Yuanming could survive until the end of the project, his achievements in two bombs and one star would definitely not be judged, but he should be an academician of the Chinese Academy of Engineering.
Strange to say.
Such names and deeds that Xu Yun should not be able to remember, actually appeared clearly in his mind at this time.
But Xu Yun couldn't care so much, after all, the deeds of such seniors should not be forgotten.
Don't ask, just ask because my memory suddenly improved a lot.
At this moment.
What Xu Yun really cares about is...
Although now, due to his presence, there are basically no quality problems at the detonation test site, the risks in the experimental process still exist.
For example, in the original history.
Yao Xiaolin and his son and Gao Yuanming and his son were just one of the ancestors who died. There were more than 70 martyrs during the entire detonation test.
therefore.....
Can you think of some ways to avoid this happening?
Within a very short period of time.
Many thoughts flashed through Xu Yun's mind.
first.
The best way to avoid sacrifice...or the only way is to prevent any personnel from staying at the explosion site.
The reason why Gao Yuanming and the others wanted to stay in the safe room next door was to collect data as soon as possible.
In other words...
When the arrow of the whole thing reaches here, it points in one direction:
Instruments for collecting data.
After all, it is precisely because of the lack of sufficient instruments that operators need to collect data as soon as possible.
When it comes to measuring instruments for bomb performance, one country must be mentioned:
Germany.
For example, TJ Wilberland, the inventor of TNT, is a German.
During World War I and World War II, German explosives were also famous.
The first standard missile in modern history was developed by the Germans.
Although Germany's weapons and troops have been castrated from Chen Kun to Kun Kun after World War II, Germany's technological level...especially the level of instruments has not fallen but has risen.
Even in the later generations when Xu Yun traveled through time.
German brands such as Zeiss, Bruker, Eppendorf, and Sartorius still occupy the top echelon positions.
Therefore, if you want to accurately measure the explosion effect, Germany is obviously a very good trading partner.
but......
Under the current situation, how can we obtain a large number of precision instruments from Germany?
Suddenly.
Xu Yun thought of his previous plan again.
etc......
If you add Germany to the plan, and then this and this and that...
Xu Yun thought for a moment, and finally shook his head in frustration.
No, no.
Still not enough.
In this plan, there is still an extremely crucial link missing.
If that problem is not solved, there is absolutely no chance that the plan will be realized.
But......
Where is the opportunity for that part?
that's all.
With Xu Yun's somewhat solemn expression, the inauguration ceremony of the detonation test site finally came to an end.
Follow the relevant plans of the base.
Around January next year, several workstations will conduct relatively large-scale explosive experiments.
But if it develops according to normal history.
The explosive casting engineer named Liu Zhendong would create the Mikhailov pot like a cheat within two months, allowing the rabbits to quickly start research and development of explosives.
Therefore, the time left for Xu Yun is most likely only two months...
...........
Shortly after the inauguration ceremony of the detonation test site was held at the base.
The Coca-Cola trading group led by Liu Yunquan also arrived in Moscow successfully.
But Liu Yunquan probably would never have thought that the upcoming Coke Exhibition would become an indelible and important turning point in this timeline.
There is a saying that goes well.
Human elites can only steadily advance the historical process, but it is often an ordinary little person who really changes history.
Even in many cases, those little people don't actually know that they have changed history.
........
Note:
Good news, the story about the furry bear can be written.
The bad news is that the requirements are still very strict. The manuscript I wrote before has to be revised a few hundred million points. It can be said that the saved manuscript is almost scrapped.
