Into Unscientific Chapter 619

  Mentioned it a long time ago.

Just as the material platform and storage warehouse of the base belong to two different factory areas, the 12th Branch Factory and the 17th Branch Factory respectively, the base's explosives R&D unit and explosives testing site are also not in the same factory area.

  Among them, the person responsible for the testing, collection, and analysis of explosive performance is the Sixth Branch Factory where Gao Yuanming, Xu Yun and others work, which is also the detonation laboratory.

 The specific research and development of explosives is located in the second branch factory further away, and is completed by a team of 40 people and equipped with a production workshop.

Hence, every explosive performance test at the base is actually an interaction between the two branches.

 Half an hour later.

Wang Yuan, then the deputy chief engineer of the Second Branch Factory and the head of the explosives project, hurried to the basement of the Sixth Branch Factory with a group of people.

Wang Yuan is a middle-aged man wearing an old beige short-sleeved shirt and a cotton hat. He is about 1.6 meters tall and has a sallow complexion. He looks very friendly with a smile.

However, Xu Yun noticed that Wang Yuan's left earlobe was obviously missing a small piece of flesh. It seemed that he was probably a person with a story.

Wang Yuan had a cigarette stuck in his missing earlobe. For a short period of time, Xu Yun had an idea in his mind to ask if the cigarette was King Furong.

 After all, the name Wang Yuan is quite funny when paired with cigarettes.

Of course.

This thought lasted for a short time, and was dismissed by Xu Yun after a while. Someone was not worthy to be compared with a senior like Wang Yuan.

 Subsequently, under the introduction of Lao Guo, Xu Yun quickly greeted Wang Yuan and others:

 “Hello, Engineer Wang.”

 “Hello, Consultant Han.”

 After the simple greetings.

Gao Yuanming looked at Wang Yuan again, raised his chin towards him, and asked:

“Old Wang, have you brought your explosives?”

Wang Yuan hummed after hearing this, and turned slightly to one side, revealing several boxes behind him:

“Brought it, it's all here, the explosives and equipment have been assembled.”

Gao Yuanming nodded with satisfaction.

Then he looked at the watch on his wrist and saw that the pointer was already moving towards ten o'clock. He quickly waved his hand and said:

“Okay, now that we have brought everything, let's hurry up and set up the scene, just in time to try out whether the components produced by the Germans work well or not!”

“If everything goes well, we can also taste the winter wheat from Mao Xiong. I heard that the cornstarch made from this stuff is quite fragrant.”

 Wang Yuan and others have no objection to this.

 Soon, Wang Yuan and many engineers began to move boxes into the testing site.

 Xu Yun, Lao Guo and others stayed aside and became spectators because of their inconvenient mobility and lack of expertise.

 Every student who has developed high explosives knows this.

 As of this period, there are a total of three generations of explosives products in existence.

The first generation of explosives was nitric acid explosives improved by Nobel, the Swedish explosives king.

 The second generation explosive is the TNT explosive invented by German chemist Will Brandt.

 The third generation of explosives is also made by the Germans and is called RDX.

Nowadays, TNT and RDX are common types of explosives in various fields, and they are also used frequently in the military industry.

But on the other hand.

Although second- and third-generation explosives are very powerful, ordinary TNT and RDX are not enough for weapons of the magnitude of atomic bombs.

 Mentioned earlier.

The principle of the atomic bomb is atomic fission, using neutrons to impact the atomic nucleus.

This impact is not just like throwing things away. It requires neutrons to impact the atomic nucleus at high temperature and high speed in order to induce nuclear fission.

 To enable a reaction to begin.

The basic approach of various countries is to use high explosives to generate huge shock waves and high pressure when they explode, compress the nuclear fuel to a critical state, and produce nuclear fission.

 Generally speaking.

A nuclear bomb with a nuclear charge of 60 kilograms needs to be equipped with high-energy explosives to detonate, which will cost upwards of 2,000 kilograms.

at the same time.

  The time required to generate shock waves and high pressure when a nuclear weapon explodes must be on the order of ten thousandths of a second. Therefore, the high explosives used in atomic bombs are not enough simply to pile up, but must go through extremely complex proportions.

 This method of matching is to combine TNT and BlackSoft Finance and try to match the ratio time and time again.

 Then the fused explosives are tested at the detonation test site, and the increase or decrease in proportion is optimized through the test explosion effect.

 Subsequently, under the watchful eyes of Xu Yun, Lao Guo and others.

Wang Yuan and others quickly took out some large and small things from the box. Some were clay pots, some were plastic boxes, and some were equipment parts made of metal.

Then Wang Yuan and others placed them in the test site according to the predetermined positions and began to finally debug the linear oscillation detection components.

 About half an hour passed.

Gao Yuanming led Wang Yuan to Xu Yun and others. Gao Yuanming wiped the sweat from his forehead and said:

“Director Guo, Consultant Han, we have almost prepared everything we need to prepare. Let's go to the ground now.”

I have to say that Gao Yuanming is quite a bachelor.

Although at this time, he probably still disliked Xu Yun for wasting resources, he didn't resist in action. This can be regarded as a characteristic of people in this era in terms of execution ability.

 The group of people then took the lifting platform back to the ground again, and came to a house far away from the test site building.

This room is a ground observation area that the base began to build after the Rabbit reached a deal with Germany. It is specially used to house observers who perform detonation experiments.

 A few more minutes passed.

A man in his thirties hurriedly ran out of the basement and came to the observation room:

“Senior Engineer, King Engineer, the countdown to the ignition device of the explosive has begun!”

Gao Yuanming nodded calmly:

"Thanks for your hard work."

The conditions for detonation experiments these days are limited, and it is difficult to transmit instructions directly through computers as in later generations. The experiment can only be guided by manually activating the countdown device.

Even on the day when the nuclear weapon actually exploded, the rabbits only used a wired automatic control system. The control tower was more than 20 kilometers away from the center of the tower.

 Fortunately, this countdown process is not risky. After Xu Yun's repeated request, the Sixth Branch Factory set a 20-minute countdown.

　　Including the time it takes for the operator to close the door, go upstairs, leave the building and arrive at the observation room, it only takes ten minutes.

 After the last member entered the observation room, Xu Yun and others waited patiently for the countdown.

ten minutes.

 Eight minutes.

 Four minutes.

One minute

When the time came to 10:17 in the morning, there was suddenly an undetectable vibration on the ground beneath Xu Yun and others.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 score

 The duration of the vibration was so short that not even a particle of dust fell from the observation room.

It is clear.

The quality of the base detonation laboratory is still very high—after all, in terms of yield, this is already one-twentieth of the maximum cold explosion magnitude.

However, for the sake of safety, Lao Guo waited a few more minutes to make sure everything was OK before leading everyone out of the observation room and back to the underground testing site.

The aisles of the underground testing site were still as clean as ever, but after a few engineers opened the door to the testing site, a puff of smoke rushed out.

　　　　　　　　　　　　　　　　　　　　　　ifies

Xu Yun quickly waved away the smoke and dust with his hands, and at the same time looked up at the interior of the test site.

 I only see this moment.

 A lot of smoke and dust floating in the air can be vaguely seen in the test site, and there are also various gravels on the ground near the wall.

As for the center of the field, the parts that originally contained explosives had cracks of varying sizes, and the entire field was in a mess, as messy as the dormitory of a senior in later generations.

 Qiao Caihong couldn't help but widen his eyes when he saw this kind of scene for the first time, looking quite surprised:

 “It's so powerful”

Gao Yuanming smiled when he heard this and said nothing.

 Just kidding, this is 120 kilograms of TNT mixed explosive. Is it not very powerful?

 It is well known.

The energy of 1 kilogram of TNT is approximately 4.184 megajoules, or 4,184,000 joules.

  What is this concept?

  For example.

This energy can move a kilogram object 420 kilometers, or a 100 kilogram object 4.2 kilometers, and move the base of an ear.

One kilogram is like this, let alone 120 kilograms of TNT mixed with RDX.

 In terms of magnitude.

 The power of 120 kilograms of TNT explosive is basically equivalent to the explosion of an 800-liter oil tanker.

If you still can't understand the video of the liquefied gas tank exploding, have you watched the video?

The calorific value of 1 kilogram of liquefied petroleum gas is about 46,100 kilojoules. The explosion effect of a full household gas tank is almost as powerful as the explosives Xu Yun and others experimented with today. You can find videos of gas explosions at home and abroad by searching online. Many exploding gas tanks are actually not full.

The area of ​​tens of thousands square meters of Workstation No. 5 is quite large, but it is also quite small. In addition, Gao Yuanming and the others had placed a lot of measuring objects in the test site beforehand, so it is normal for such a messy scene to appear.

However, although the test site was filled with dust, Gao Yuanming and others had no intention of waiting for the dust to fall to the ground before taking action.

Gao Yuanming and the others were seen magically taking out a few pairs of cotton and linen labor protection gloves and putting them on their hands. Then they covered their mouths and noses and rushed into the venue quickly.

Gao Yuanming didn't forget to assign the task while running. After a while, he could only hear his voice but not see his person:

 “Xiao Xu, go and take a look at the location of component No. 1!”

 “Lao Ma, you are responsible for component No. 4!”

“Xiao Wang, go find the wooden stake of component No. 5”

 At the same time, the employees of the Sixth Branch whose names were mentioned by Gao Yuanming also responded one after another:

"receive!"

"yes!"

"clear!"

Upon seeing this, Lao Guo couldn't help but look at Xu Yun and shook his head slightly:

 “This is Lao Gao. Come on, Xiao Han, let's go to the edge and wait.”

Xu Yun had nothing to do with Gao Yuanming in this matter, so he had no choice but to follow Lao Guo to another observation room and wait.

This observation room is no different from the one on the ground, except that the walls are thicker—this room was originally planned to be used for observation, so as to ensure that various experimental parameters can be obtained as soon as possible.

 More than ten minutes later.

Gao Yuanming and others walked in from the outside carrying several boxes.

These boxes are the receiving equipment for the sensors. During the experiment, Gao Yuanming and his colleagues placed them in a very safe corner, and they were also surrounded by iron sheets to form a protective shell.

While Gao Yuanming was placing the boxes, Wang Principle took out a dotting timer from a corner of the observation room.

“Lao Gao, where is the power supply?”

“There is a socket in the cabinet on the left, just plug it in.”

"okay!"

 After tinkering for a while, Wang Yuan and others quickly began to read the data in the receiver.

This receiver is a relatively primitive storage device. It is said that it has a mercury delay structure and a gear storage module inside, and it also has a card reading strip recording function.

One such device can record the parameters collected by up to six linear oscillating elements, and exactly four are needed for the 24 element placement points in the entire test site.

 After powering on.

 The receiver soon began to output recording information.

  Click click click—

Gao Yuanming stood beside the timer and began to read the note seriously.

“B1 is 1848586873456, which is interpreted as an explosion velocity of 7164.56 meters.”

  “8938438485 correction amount is +120”

“The explosion pressure of element 13 is 3.23e9pa”

“The density of element 17 is.”

 As the cards were typed out one after another, groups of parameters appeared in front of everyone one after another.

 Mentioned earlier.

The position and even the orientation of each group of components have been rigorously calculated in advance. Therefore, after summarizing the parameters of each group and deriving them, data such as the initial velocity of the explosive and its diffusion trend in space can be accurately restored.

 Half an hour later.

Gao Yuanming handed a piece of calculated data to Wang Yuan:

 “Old Wang, take a look.”

Wang Yuan took the report and glanced at it quickly, his brows quickly knitted together:

“The explosion velocity is 7434 meters. It is still too slow. In addition, the peak overpressure of the shock wave is not good. It seems that the ratio needs to be adjusted again.”

 It is well known.

Henrych once derived two formulas based on a wide range of experimental research work on the explosion of TNT charges:

ToW√3=103(0.107+0.444Z+0.264Z20.129Z3+0.0334Z4)0.05≤Z≤3

To=B×103×W√6R√

 The meaning of these two formulas is the time parameter of the shock wave, which is also the core mathematical basis for most explosive data research in this era.

  However, this formula is purely mathematical experience after all and cannot correspond to every experimental environment one by one.

 For example, Xihai Province has high altitude and low air pressure, and the boiling point of water is very different from normal. This model is naturally invalid in Xihai Province.

Because of this, Wang Yuan and others can only rely on pure manpower to optimize the explosives, that is, judging whether their direction is right or wrong based on the explosion data.

 Obviously, this time they failed again.

Seeing this situation, Lao Guo on the side couldn't help but patted Wang Yuan on the shoulder twice and comforted:

“It's okay, Engineer Wang. If the result is not ideal, it's not ideal. At least these parameters can be reversed to prove that the components the Germans gave us are quite accurate.”

“With these components in hand, explosives that meet the conditions can always be slowly prepared.”

Unexpectedly, Wang Yuan shook his head and did not accept Lao Guo's comfort:

“Director Guo, what you said is wrong.”

“Our high explosives are not just about changing the ratio of TNT and RDX, but the more important thing is to fuse the two.”

"To be honest, the batch of explosives we tested today is already the best batch of finished products. If we want to increase the explosion speed and overpressure, we must create a Mikhailov pot that can further integrate the two. OK."

“But the problem is that Mao Xiong didn't even give us a drawing of this technology. Unless we get lucky, it's impossible to come up with such a tool.”

 “Without the Mikhailov pot, how can we talk about the so-called blending?”

Looking at Wang Yuan who kept shaking his head, Lao Guo couldn't help but be slightly startled.

 Mikhailov pot?

He had heard of this tool before - his teacher when he was an intern at the reactor had mentioned it to him.

 At the same time, as the deputy director of the base, he quickly thought of one thing:

 At the time, there was indeed no information about this technology in the list of Bear support technologies.

 That's right.

 It was not that Mao Xiong later burned the relevant drawings, but that there was no technology to use the Mikhailov pot as an aid at all.

Although he didn't know much about explosives research and development, this lack of tools to continue research is also quite common in fluid mechanics, so he could indeed understand Wang Yuan's difficulties.

Thinking of this, Lao Guo couldn't help but frowned.

 A few seconds passed.

 He turned his head subconsciously and asked Xu Yun:

 “Xiao Han, do you know anything about this Mikhailov pot?”

Lao Guo's question was an instinctive reaction. After all, Xu Yun had given him many surprises, big and small.

 But to Lao Guo's regret, Xu Yun did not give a definite answer this time:

“Mikhailov pot, Mr. Guo, I have heard of this thing, but I really don't understand the specific principle. I only know that it is a tool for burning explosives.”

 Lao Guo was stunned for two seconds when he heard this, and then sighed sadly.

Too.

This Han Li is not from the future decades later, how could he know everything?

 This kind of thing can only be done by taking risks and manpower.

Just when Lao Guo was about to speak to Wang Yuan, Xu Yun's voice rang out:

"but."

Lao Guo was startled and asked subconsciously:

 “But what?”

Xu Yun glanced at him and raised the corner of his mouth again:

"But although I don't know how to make the Mikhailov Pot, I once heard a man named Altaïr Ibn say something like"

“Killing all the witnesses is a perfect assassination.”

 A question mark suddenly appeared on Lao Guo's face:

 “Xiao Han, what do you mean?”

Xu Yunjian pointed to the remaining explosive powder not far away and explained:

“Guo Gong, what is the purpose of making Mikhailov pot?”

Lao Guo gave him a strange look, but still answered honestly:

“Of course it's to prepare more powerful high explosives.”

Snapped!

Xu Yun snapped his fingers cheerfully and shrugged towards Lao Guo:

“So, if we directly develop a more powerful explosive, wouldn't it be equivalent to creating the Mikhailov pot?”

 Say it.

Xu Yun glanced at Lao Guo again, who was in a daze, and said with a smile:

“Guo Gong, have you heard of CL20?”
