Rule department scholar

"The other one seems to be the alloy material expert of the first voyage? It is said that he was invited by the academician and came together?"

"should be."

"However... what kind of power and machinery does Zhao Yi know? I guess he just came to join in the fun."

"..."

Ying Shaowen coughed lightly, and the venue immediately fell silent.

Zhao Yi and Zhang Hongtao found a seat in the back row, fully prepared to be spectators, and the meeting proceeded normally.

This internal research and development meeting is a discussion on the internal design of the new engine. First, the overall design drawing is played. Each relevant researcher gives some opinions and suggestions on the part he is responsible for, and discusses the problem points separately.

Zhao Yi listened to it with interest. It was his first contact with the field of engine design, because it was only the application of technology, and the design principles were still understandable.

As the meeting progressed, he felt that he had learned a lot, but Zhang Hongtao next to him was drowsy. If he hadn't fallen asleep directly, he would probably have fallen asleep on the table.

The meeting went on for about half an hour, and there was no dispute over one issue, which was the structure of the engine fan blades.

Some people suggest using hollow fan blades, while others think that curved solid flat blades are better.

Hollow fan blades are better with hollow fan blades.

The solid flat leaves of the arc certainly have their advantages.

If it is only analyzed from the perspective of providing power, it will involve very complicated calculations, and according to experience, the value of the difference in power supply will not be very large, but in any case, the finalization of similar plans must be supported by scientific data. Definitely can't decide for a while.

Therefore, the dispute in the meeting cannot be resolved.

Ying Shaowen listened to the arguments of his subordinates, and found that Zhao Yi was sitting in the back row listening very seriously, so he took advantage of the spare time and asked Zhao Yi expectantly, "Academician Zhao, you are an expert in mathematics and physics, can you Help us calculate, how big is the difference in the power provided by the two schemes?"

Chapter 4 Because Zhao Yi is a genius!

Ying Shaowen asked Zhao Yi about the fan blades of the engine and the provision of power support. He did not want to let him calculate on the spot, but wanted to interrupt the debate at the meeting and send a signal of 'wait for the calculation results to come out'.

The calculation must be very complicated, and it is impossible to get the result in the short term.

Even if Zhao Yi agrees to help with the calculation, because there are so many factors involved, it will take a long time to understand it, and it will take even longer to perform very complicated calculations.

After the calculation is completed, provide the support of the calculation results, and then discuss it with a scientific basis for reference.

It doesn’t matter if Zhao Yi refuses to help, they can do similar calculations slowly, but they don’t know how much time it will take, and they are not 100% sure of the accuracy of the results, and Zhao Yi is a top mathematician and physicist , the calculation results are of great reference value.

Zhao Yi's understanding was different.

He didn't know the difficulty of the calculation. He thought that Ying Shaowen wanted him to express his opinion, and then he calculated it on the spot. He thought carefully and said, "Only from the perspective of power supply, the effect of the solid flat leaf scheme of the arc better……"

"Why?" Ying Shaowen asked subconsciously.

"Is this..."

Zhao Yidao, "I'm pretty sure that the arc's solid flat leaf scheme can provide more power. But, if you want accurate data, I need to do a serious calculation."

After saying that, he spread his hands.

Ying Shaowen was stunned for a moment before realizing that Zhao Yi and Zhang Hongtao didn't have any information in their hands. He hurriedly asked someone to bring a copy of the detailed information, and continued, "It's great that Academician Zhao can help."

"It's nothing, I just listened to it anyway, I learned a lot."

"You are too modest."

The two exchanged a few words.

Ying Shaowen continued to preside over the meeting. His understanding of Zhao Yi's "calculation" was that it would take ten days and a half months to help out after going back. He didn't pay attention to it, but let everyone rest for 10 minutes and I also went to the bathroom when I found time, and waited for a while when I came back. I had to check the time to stagger the topic and enter the discussion on the next topic.

"under……"

Just as Ying Shaowen opened his mouth, he noticed that Zhao Yi looked over, as if he was about to say something.

"Academician Zhao?"

Ying Shaowen looked a little puzzled. He felt that Zhao Yi was not the kind of person who intervened in the meeting by posing as a 'big name'. It would be impolite to plan to host the meeting in the middle, but he still said in a questioning tone, "There is What's the matter? Academician Zhao?"

Zhao Yi was not only a little puzzled, but also said in a dissatisfied tone, "Didn't you ask me to help with the calculation just now?"

"Yup?"

"I've figured it out!" What he meant was, 'I've already figured it out, but you seem to have forgotten it'.

"What counts?"

Ying Shaowen was stunned for a moment and asked, "What's the deal?"

This time Zhao Yi said very dissatisfied, "It's the problem with the fan blade plan?" The power efficiency is 21.4% higher, but the maximum power is about 15.00% lower than that of the hollow fan blade.”

"..."

"..."

"—?!!"

Ying Shaowen was stunned when he heard that.

The others were also stunned.

Everyone looked at Zhao Yi in surprise. They never expected that Zhao Yi would directly say "forget it" and a series of seemingly detailed data?

how could it be possible!

How long has it been!

It does not sound complicated to provide power by the structure of the fan blades, but because the shape and structure of the fan blades of each scheme are not 'regular graphics', coupled with the dynamic problems involving the influence of 'hollow', the calculation involves a huge amount of data , is still very complicated. Even if you know how to calculate it, it will take a lot of time and energy. If there is a little error in the middle, it will affect the accuracy of the result. It is best to calculate several times to ensure that the calculation result is accurate There will be mistakes.

Zhao Yi, is that all right?

10 minutes?

Zhang Hongtao was sitting next to Zhao Yi, his surprise was no worse than the others, and he even felt that Zhao Yi was 'telling lies', just now he watched Zhao Yi's calculation process, just kept writing symbols, numbers, symbols on straw paper , Numbers have no rules at all, after writing a lot...

Forget it?

"He was calculating just now? But why is there no process? Do top mathematicians do calculations like this?" Zhang Hongtao thought about whether the calculation methods of top mathematicians are different from others.

The venue was quiet for more than ten seconds.

Zhao Yi looked left and right, feeling a little baffled, he asked in confusion, "What's wrong? Is there something wrong?" He also looked down at his clothes, worried whether he would make a fool of himself because of the clothes.

Ying Shaowen took a deep breath. Like the rest of the team, he did not expect Zhao Yi to be able to calculate it quickly. If they did a similar calculation, they would first list the data and then analyze how to calculate it.

Then, calculate it subdivided.

This is definitely a very complicated math problem, and it cannot be calculated with a few formulas. Even experienced people with good math skills need to think slowly to do the calculation. Maybe the sky will have a result?

Zhao Yi finished it in 10 minutes?

It's impossible for a top mathematician to be so fast, right?Could the gap be that big?

Ying Shaowen looked up at Zhao Yi, and asked carefully, "Academician Zhao, are you joking?"

"joke?"

Zhao Yi felt a little baffled, "Didn't you ask me to help with the calculation?"

"Ah... yes."

Ying Shaowen didn't know what to say, could he just say 'you calculated too fast, I thought you were joking'?

This will definitely not work.

Zhao Yi is the world's top mathematician, shouldn't he joke about calculations and data?It seems that he is very serious, and he will not joke on this occasion.

Anyway, it's not good to continue to question.

Ying Shaowen calmed down a little, but still couldn't help swallowing, and then put on a clear gesture, and said simply, "Then, now that there is a result, let's continue discussing the fan blade issue."

The atmosphere of the ensuing discussion was a little weird.

The few people who had been arguing fiercely before just stopped talking after a few words, making the venue quieter, and Ying Shaowen hurriedly moved on to the next content.

Soon the meeting was over.

Ying Shaowen sent Zhao Yi and Zhang Hongtao to the door, and someone took them to various places in the department, and finally arrived at the office of the core material department. A researcher named Sun took them to the operation room.

The aircraft carrier steel plate is stored inside.

Zhang Hongtao came here for this aircraft carrier steel plate, and his superiors hoped that he would be responsible for researching the aircraft carrier steel plate and finding out how to manufacture and produce it.

Zhao Yi was also very interested in the steel plate of the aircraft carrier. He tried to lift it up and weigh it, and then started a routine analysis with Zhang Hongtao.

the other side.

The engine research and development team led by Ying Shaowen is busy, and the whole team is doing one thing--

Calculate the power difference provided by the two fan blade schemes.

Before, they were not in a hurry to do similar calculations, because the calculations were very complicated, and the design was still in the early stage. Even if the calculations were done, they might not be finalized. Now the thinking is different.

Even if it is not for choosing a plan, everyone hopes to calculate the data, just to verify at a glance whether Zhao Yi is joking, or really counted you out.

Also, is Zhao Yi right?Are you sure?

"Certainly not!"

"Yes, it can't be that fast! If it's true, it's too perverted! It should be a joke."

"But, academician Zhao has no reason to talk nonsense, right?"

"I believe that Academician Zhao is serious. Although I can't understand it, think about it, is Zhao Yi an ordinary person? He is a pervert! Pervert, you know? He is not a normal person at all, normal Can a person solve several world math problems in a row?"

"Right……"

"We are just ordinary people, it is impossible to understand genius..."

"No matter what, I still don't believe it!"

"..."

The discussion of the whole team was in full swing, and they were all assigned calculation tasks. Each group did a part of the calculation, and when combined together, the results could be obtained. They did not need accurate values, as long as the deviation was not too large, because their purpose It is verification, not really calculating the exact value.

Ying Shaowen's mentality was the same as that of the others, he was curious whether Zhao Yi was joking or not.

Believe?

How can this be believed?

Ying Shaowen is an expert in dynamics and an academician of the Academy of Engineering. He has been doing scientific research all his life. He thinks that his mathematical ability is not bad. He must not be as good as a top mathematician, but his computing ability is not much worse, right?

He thought about it carefully. The same problem needs to be calculated. Even if the result is vague, it will take more than three days. Compared with Zhao Yi's 10 minutes, it is not a level at all.

"Am I a fool?" Ying Shaowen said with a self-mockery, but he still didn't believe what Zhao Yi said was true. He also assigned himself part of the calculation work, and immediately threw himself into the work.

……

When a team is doing calculations and has done a detailed division of labor, the calculation speed will become very fast.

Many people simply worked overtime in order to get the results. By the next morning, everyone in the team had almost completed the calculation tasks. They came early. When they first arrived at work, the small meeting of "summarizing data" It was held.

Ying Shaowen got all the calculated data, asked two staff members to record on the computer, and then made summary calculations together.

Summarize, it's easy.

The calculation assigned yesterday was a very complicated and difficult task. The summary of the math problem became a calculation problem that did not exceed the junior high school level at most. If a group of people did the summary calculation together, the result would definitely not go wrong.

"What's the result? The scheme of the arc solid flat leaf should provide higher power data, right?"

"Yes, mine was 19 to 24 percent."

"It's about the same for me."

"If the ratio of the fine circular axis area is drawn into a straight line, the data should be between 20 percent and 22 percent."

"So that's almost the same number. By the way, what was Academician Zhao's statement yesterday?"

"... 21.2 percent."

"..."

"..."

Many people in the conference room fell silent.

Ying Shaowen took a deep breath and continued to ask, "What about the calculation of the maximum power? How high is the hollow fan blade?"

Someone next to him said, "Yeah, mine was 13 to 16 percent."

"I am also the data."

"There should be more than 14 points, right? I calculated the arc part as an approximate arc, but the data can only be low, not high."
