Chapter 174 To the Glorious People (Part 2) (5.6K)
More than a week ago.
After deciding to build the aircraft.
Xiao Zhao quickly fulfilled his promise:
While preparing various types of ore materials.
A large team was quickly organized.
The total number of people in this team is over 700, and about half are craftsmen, a total of more than 300 people.
The top technician among them is Siegfried.
There are also three top-notch craftsmen from various places, who are the ‘eighth-level craftsmen’ of the Song Dynasty.
This ratio is actually quite normal.
Take 1959 as an example.
At that time, there were more than 70 million skilled workers in the country, including more than 1,300 eighth-level workers recorded by the Ministry of Machinery.
The first generation submarine, the first missile, the first atomic bomb, and the first space satellite are all inseparable from the hard work of the eighth-level workers.
The current population of the Song Dynasty is about 100 million, which is far from the billions of later generations.
And the number of workers engaged in handicrafts is not as large as that of later generations, but it is still normal to produce three or five talented people with eighth-level workers.
After all, the key to level eight workers ultimately comes down to manual ability.
There is definitely a correlation with mechanical and technological foundations, but it is not particularly close.
Some ancient skills, such as silk weaving and emerald weaving, are no less difficult than the requirements for level eight craftsmen.
According to Xu Yun's plan.
in the second half of the entire production process.
These craftsmen will take on important mold casting tasks, which directly determines the finished product rate of the aircraft.
And in addition to the craftsman module.
The remaining half of the team members were all recruited by Xiao Zhao.
Numeracy expert.
Like said before.
Scientific research will never be a one-person affair.
Because of his experience in his previous life, Xu Yun could design the engine parameters on his own—or in other words, he could only rely on himself.
Because in this era, no one else has the ability to design engines except him.
But beyond the engine design.
The calculation of many data must rely on the assistance of others.
This batch of calculation teams was recruited from all over the country, and the leaders were mainly Lao Jia.
At the same time, Han Gonglian, Liu Yi and others also held middle and senior positions in the team.
Although they also do not have the knowledge base related to engines and fluids, their computing power is at the top in this era.
In some cases, Xu Yun only needs to give conditions and equations.
Even if the concept is a bit out of scope, a group of dozens or more people can still come up with results after calculation.
After all, in the three or four months between the death of the Queen Mother and the coup, Xu Yun instilled fresh knowledge into Lao Jia and others.
In recent times, even partial—note, partial—calculus has been covered.
This calculation team was also placed in the weapon making bureau, and Xiao Zhao planned a huge courtyard for them.
When Xu Yun came to the entrance of the courtyard, the courtyard was very lively:
Maybe it's because of the limited space.
It was already dark at this time, but there were still a large number of tables placed in the courtyard, with hundreds of people doing mathematical calculations among them.
Some of them calculated data silently alone.
There are also those who work together in twos and threes.
Others seemed to have encountered some problems and were gathering in a corner to discuss quietly.
For example, the side near the entrance at this time.
There were seven or eight mathematicians who looked like scribes gathered together, as if they were communicating something.
Seeing this, Xu Yun walked up to a few people and listened with interest.
The first person to speak was a middle-aged man in yellow clothes. He pointed at the two pieces of math paper on the table and said:
"Brother Ou, the thickness of the valve plate is one hundredth of an inch, and the nozzle cross-section is set to Tianyuan."
"The volume has been determined, but why are the results calculated by you and me different?"
Another thin, dark man heard this and stretched out his finger to draw a horizontal line on a certain column:
"Brother Zou, in my opinion, you may have miscalculated the value called 'axial force'."
"The prefix should be one-third, not one-quarter."
The scholar surnamed Zou in yellow clothes shook his head and said:
"No, no, I followed the curved gradient equation taught by Mr. Tongyu. The value must be one quarter. You were wrong."
Xu Yun listened for a while and almost understood the problem these scribes were struggling with:
Simply put, this is a calculation of thrust per unit section under the definition of the same thrust-to-drag ratio.
It involves the thickness of the valve plate and the cross section of the nozzle, as well as the issues of reflection and sound speed.
When I was organizing a calculation team.
Considering some conceptual issues, Xu Yun and Lao Jia specially produced an instruction manual.
Some hyperdimensional concepts are defined in the manual,
For example, the gravitational constant is 6.67259×10N·m/kg, the speed of light is 300,000 kilometers per second, and so on.
In other words, you don't care where the number comes from, just use this number and report the answer in the end.
An instruction manual is like an instruction manual,
Ordinary mathematicians can calculate directly through relevant formulas whatever data they are assigned.
However, although the formula is fixed, in some situations it is difficult to judge which entry to use.
Therefore, it is not surprising that there are some controversies.
The arguments between the two seemed reasonable, and the few scribes around them seemed a little uncertain.
Just when neither of them was convinced by the other.
The thin black scholar named Ou suddenly noticed Xu Yun eating melon.
At this time, Xu Yun was wearing regular clothes. The scribe surnamed Ou thought that he was also a member of the calculation team and asked:
"Brother, what do you have to say?"
"Me?"
Xu Yun was stunned for a moment. After confirming that the other party was asking him, he remained silent for a moment and said in deep thought:
"I dare not take my opinion seriously, but I can barely judge whether the direction of solving the problem is right or wrong."
The scribes surnamed Ou and scribes surnamed Zou looked at each other and did not look down upon Xu Yun because of his age. After all, those who could come to this courtyard were novices:
"The direction of solving the problem? Brother, please elaborate on it."
Xu Yun thought for a while, then stretched out his hand to draw the shape of the combustion chamber:
“According to the design drawings of the engine, we can know that the feed inlet and interface are horizontal.”
"It can be seen from this that the temperature in the combustion chamber must be different, that is, the temperature in the area near the fire is higher than that in front of the front pressure wave."
"According to the 39 formulas in the manual, we know that pressure waves are a type of sound wave, and the speed of sound has a functional relationship with temperature."
"Therefore, when the cross-section rebounds, the back wave will inevitably catch up with the front wave, and we can only use the gradient of the curve to start."
Speaking of this, Xu Yun couldn't help but look at the scribe named Zou:
"So I dare not say that Brother Zou's data has no calculation errors, but at least I can be sure that his thinking is correct."
"If you repeat the calculation several times, you will be able to get an accurate value."
Bang bang bang——
As soon as Xu Yun finished speaking, a round of applause suddenly sounded from the side.
Xu Yun took advantage of the situation and looked around.
I don't know when Liu Yi came to him quietly.
I saw Liu Yi applauding and laughing:
"Young Master Wang has a clear mind, he hits the nail on the head, and his words are concise and clear. Liu is really impressed by him."
Seeing Liu Yi appear, several scribes quickly straightened their expressions and said respectfully:
"Hello, team leader."
Xu Yun also bowed his hand:
"Mr. Jinqu, long time no see."
Liu Yi returned the greetings to everyone in turn, pointed at Xu Yun and said to everyone:
"I'm afraid some of my comrades don't know something. This is the famous "30,000 updates a day" Wang Xiaochun, Mr. Wen Huanong."
"The "Standard Manual" that these few people have been studying day and night was written by Mr. Ma Nong and Mr. Tongyu."
Hearing Liu Yi's introduction, the scholar surnamed Ou was suddenly surprised and stood in awe:
"It turns out to be Mr. 30,000 coders a day. Xiao Ke has long admired his name. I'm rude. I'm rude."
Xu Yun also arched his hands towards him, his expression looking very calm.
Still the same sentence.
Wang Lin is the one who updates 30,000 yuan a day. What does it have to do with Xu Yun?
Then he said goodbye to everyone and wandered around the courtyard with Liu Yi.
"Mr. Jinqu."
Looking at the scribes in the courtyard who were lighting candles and calculating data, Xu Yun took the initiative and asked:
"Is everything going well these days?"
Liu Yi nodded, pointed to an area where the most mathematicians gathered, and said with a smile:
"Everything is going quite smoothly. The team members come from all over the world. They are either low-level officials with no ambitions, ordinary elementary school students, and some are hermits living in the mountains and forests."
"If it weren't for His Highness's grace, we would probably never see such a grand scene in this life, and naturally we would cherish it very much."
"Now we have calculated and verified more than 50 sets of data, and on average we can produce seven sets a day, which is much higher than the expected five sets."
Liu Yi's expression was a little emotional, and what he said was true from the bottom of his heart.
Although there were many well-known mathematicians in ancient China, not many could truly leave their names in history.
Except for a few cases.
Most numeracy scholars are just ordinary petty officials or ordinary teachers in elementary school.
Even Lao Jia, who counted everyone at that time, could only leave an unknown record in the history books.
Not to mention other ordinary people.
Therefore, after learning that the emperor, or to be precise, the court had invited him, and that there was a high subsidy.
Almost all the numerologists who received letters accepted the recruitment.
To some extent.
This kind of centralized calculation by mathematicians has never been seen in history, let alone the Song Dynasty.
Therefore, Liu Yi called it a grand scene, which was indeed sincere.
Then Xu Yun thought for a while and asked:
"Mr. Jinqu, where is Mr. Tongyu?"
The night was a little dark at this time. Liu Yi looked around, then pointed to a secluded cabin in the corner and said:
"Mr. Tongyu is in that room. Mr. Wang, let's go and have a look?"
Xu Yun nodded:
"Good work."
Then, under the leadership of Liu Yi, the two quickly arrived at the door of this room.
But Xu Yun didn't rush to knock on the door.
Instead, he came to the window and looked in through the carefully placed glass windows.
As soon as he saw the situation in the house clearly, he was a little stunned:
At this moment, this room with an area of almost 40 square meters was filled with stacks of calculation papers.
The arithmetic paper is partially packaged and placed in a corner.
Some were scattered messily on the ground.
On the only two tables in the room, Lao Jia and Han Gonglian were sitting respectively, both bowing their heads and calculating something.
From time to time they would yawn and rub their eyes.
But he soon cheered up and continued working.
From the mental state, it can be easily judged that the energy consumed by these two people is much higher than that of ordinary arithmeticians.
Seeing this, Xu Yun couldn't help but look at Liu Yi and asked:
"Mr. Jinqu, what is this?"
Liu Yi was silent for a moment, then sighed quietly and said:
"Master Wang, although the manual written by you and Mr. Tongyu is good, it is a dead thing after all."
"As you saw earlier, there are situations where differences of opinion are bound to arise in practice."
"So Mr. Tongyu came up with a method to assign each task to three groups for calculation. Each group will first conduct calculation discussions and determine a unified value to report."
"If the numbers reported by the three groups are the same, they will be temporarily summarized and await practical verification by Master Qi."
"But if any one of the three groups has different results, it will be handed over to Mr. Tongyu and Mr. Yang Huai, who will be responsible for re-inspection."
"Admittedly, this approach is bound to have some errors and omissions, but this is the best we can do."
Xu Yun was silent after hearing this.
After a while.
He looked at Liu Yi thoughtfully, especially the bags under his eyes for a few seconds, and a flash of realization flashed in his heart:
"Mr. Jinqu, I'm afraid you are also one of the people responsible for the re-inspection, right?"
Liu Yi pulled a smile from the corner of his mouth and said:
"There is no way. We, the six math scribes who attended the lectures in Su Mansion, are now the only six people who can do the retest."
"Master Wang, did you know that Mr. Tongyu had left a suicide note on the day the team was formed?"
"Mr. Yang Huai had a baby at home yesterday and he never asked for leave to come home."
Then he turned around and looked at the face illuminated by the candle on the piece of paper in the courtyard:
"Master Wang, in fact, it's not just the six of us. The entire team has a total of 313 mathematicians. Some may have made mistakes due to ability issues, but no one is slacking off."
"We all know the truth. Who is not tired? Who wants to be tired? But it is flying!
"For every ten thousandth of a value we calculate, we may be able to lift the plane one foot higher."
"For thousands of years in China, since the Yan and Huang generations, no one has been able to conquer the sky, but now, we have the opportunity to do it."
As he spoke, Liu Yi looked at Xu Yun again, with brilliance flashing in his eyes:
"Your Majesty, Mr. Su once told us privately that your talents are unparalleled in ancient and modern times and are rare in the world. If you say you can, then you really can."
"We may not be able to catch up with you, but we can push you as much as we can."
"We don't seek to leave a name in history, but we seek to witness with our own eyes the first trip to the sky in thousands of years. Just as Mr. Tongyu said when he wrote his suicide note, he will die without regrets. ! ”
After Xu Yun listened quietly to Liu Yi's words, a special emotion surged in his mind.
He wanted to tell Liu Yi.
In fact, I am just a time traveler from later generations, and all I have is relatively complete knowledge from later generations.
It’s not me who is truly great and great,
But you, the great sages
In later generations, we not only conquered the sky, but also touched the universe.
Mozi Satellite and Zhurong Mars Rover are all tributes and praises to our ancestors
Think of this.
He couldn't help but look at the sky.
There is not a single dark cloud in the starry sky tonight.
The bright moon hangs high and the stars shine brightly.
But in Xu Yun's view.
The starlight tonight is not in the sky, but in this world.
December 8, 1100 AD.
There is no snow, but it is the time when the Chinese stars shine. (End of chapter)
