From Almighty Scholar to Chief Scientist

Chapter 150
Hearing Lin Xiao's question, Chen Bao couldn't help laughing.

The material he is expected to study in this project is the application on the engine panel.

Especially fighter jet engines.

Fighter engines are generally small bypass ratio engines, unlike civil aviation engines with large bypass ratios. The high temperature resistance requirements of high bypass ratio engines are not as high as those of small bypass ratio engines.

In fighter jets, the service temperature of the engine wall plate is generally around 600°C, sometimes even higher, and the main stress it bears comes from mechanical loads and high-frequency vibrations.

As for the service temperature of the fan blade, it is as high as over [-] degrees Celsius, which is almost the highest temperature in the entire engine, and the rotation speed of the fan blade is quite fast, which makes the stress more complicated, which is enough to see that the fan blade has to bear How bad the environment is.

For the engine, there is an important indicator, that is the temperature before the vortex.

Generally speaking, for every 100K increase in the temperature before the vortex, the engine thrust can be increased by at least 10%, or even 20%.

Therefore, the higher the high temperature resistance of the fan blade, the higher the temperature before the vortex.

How to keep the fan blades strong at such a high temperature is a challenge for material researchers all over the world.

Therefore, the blade of an aero-engine is the most difficult material to prepare and develop. Its requirements for high temperature, high pressure and high strength make it known as the jewel in the crown of industry.

And Lin Xiao said that he wants to increase the creep resistance of their material by 100%, which is completely whimsical. If the creep resistance is increased by 100%, then the high-temperature structural strength of the material must be improved accordingly, right? There are other performance can also be improved?
Isn't this going straight to the material of the fan blade?
Then they would have to conduct more and more complicated experiments, and it would take an unknown amount of time for this, and it might not be successful in the end.

For Chen Bao, he has also developed towards this before, but in the end he chose to give up. If he wants to produce this kind of material, he does not have enough determination and perseverance, and he must have a steady stream of resources. Willing to give resource support all the time, who can guarantee that no one else will say something bad?
Now it’s not 60 years ago when the whole country was concentrating on making mushroom eggs.

Hearing Chen Bao's words, Lin Xiao smiled: "I'll just ask casually."

Chen Bao shook his head: "Titanium-aluminum alloys may have this potential, but we are definitely in the wrong direction. We need to start with the atomic arrangement structure, and consider the development of single-crystal directional solidification, but then the funding I want to apply for may be limited. There will be two or three more zeros in the back."

Their research funding for this topic is several million. If two or three zeros are added to this, it will go straight to nine or ten digits.

However, the development cost of any fighter engine is not a matter of hundreds of millions, but tens of billions or hundreds of billions. As the core component of the fan blade material, the research and development cost is hundreds of millions or billions. Accident.

Hearing Chen Bao's words, some graduate students around asked, "Boss, among the projects you have participated in before, what did you invest the most in?"

Chen Bao said with a smile: "C919, J-35, and J-[-] have also participated, and I have participated in the research on materials. These are big projects worth tens of billions."

"Wow!"

Immediately, the graduate students present showed expressions of admiration.

This is an academician of materials science!

"Okay, don't talk about it, that's it, the hero will not mention the bravery in the past, let's continue our research."

Chen Bao waved his hands, as if he was not a good man.

Hearing what Chen Bao said, the others nodded and started to continue with the work.

Lin Xiao looked at the things in front of him thoughtfully.

"System, if I ask a question worth more than 30 truth points, can the answer worth 30 truth points be included?"

System: "Yes."

Lin Xiao nodded slightly, that's all right.

Since it can be converted into when answering questions with more than 30 truth points, then he can now add 14.2 truth points to obtain the model of this new material.

However, this matter is also not in a hurry. He can study it first, and wait until he has achieved certain results, that is, after the absolute distance from his ultimate goal is shortened, and then use truth points to buy it. Maybe he can save some of it by then. point of truth.

So he smiled slightly on his face and said, "Academician Chen, let's try it now, titanium 7 aluminum 8 zirconium 1?"

"Well, try it on here now."

Chen Bao responded.

Subsequently, the calculation simulation of the second stage began.

……

Time passed quickly, and it was another ten days.

Entering April, the temperature is gradually warming up, and the weather around [-] degrees is just the most suitable temperature.

Because they identified a new material, they entered the link of new material production process design again. Lin Xiao didn't have anything to do, so he came to the campus of Shangjing University to enjoy the breath of spring.

"Well, it's been a long time since I've been in such a comfortable sun."

Walking by the Weiming Lake, bathed in the sun, Lin Xiao squinted his eyes comfortably, but it was a pity that he didn't bring Mimi here, otherwise it would be very comfortable to sit on the lawn and pet a puppet cat.

Suddenly, he felt someone slapped him on the back, and when he turned his head, he couldn't help showing surprise on his face: "Oh, Sun Yu, it's been a long time."

Sun Yu was speechless: "I should be the one who said this to you, right? I was able to see you in the school. It seems that you haven't forgotten that you are from the University of Beijing?"

Lin Xiao shrugged: "The college allows me not to attend classes, so of course I will not attend classes."

Sun Yu couldn't help complaining: "You are outrageous. You don't take a class. It's fine to get full marks in mathematics and other subjects. You can also get full marks in Sixiu. I don't know how you learn. Good guy, just get a 4.0 grade. Point, we are all number one."

Lin Xiao laughed and said, "If you count my thesis proving Goldbach's conjecture, it should be more than 4.0."

Sun Yu: "...you are awesome."

It's still the familiar formula, the familiar taste, and Lin Shen is showing off again.

At this time, a pretty girl came to Sun Yu's side.

When Sun Yu saw this girl coming, he put his arms around her shoulders and said to Lin Xiao, "This is my girlfriend, Yu Man, from the Wuyuan."

"Manman, look, let me tell you, Lin Shen and I are good brothers who have won glory for our country together."

"Hello, Lin Shen."

Lin Man also called Lin Xiao.

Lin Xiao: "..."

"Where did you find your girlfriend?"

"It's not easy to find a girlfriend...ah no, it's hard to find a girlfriend, the main thing is to put your heart into it, you have to be good at discovering, and then use your knowledge to conquer her, isn't it? Manman? "Sun Yu looked at Yu Man.

Yu Man put down the hand that was about to pinch Sun Yu, then nodded with a smile, and then said to Lin Xiao: "It must be easy for Lin Shen to find a girlfriend. The girls in our school often talk about you. If you want to find a girlfriend Girlfriend, tell me, I'll greet them directly."

"No need, no need." Lin Xiao waved his hand.

Sun Yu laughed and said: "Shen Lin is not like us mortals, Manman, don't even think about it, let him go alone."

Lin Xiao: "..."

Believe it or not, I will find you a girlfriend right away?

With how handsome we are, why can't we find a girlfriend?

"By the way, Lin Shen, do you want to form another team? To participate in the Qiu Chengtong Math Competition, we will have a stable subject."

Then Sun Woo asked.

Lin Xiao waved his hand: "I won't go, I'm taking part in a project recently."

"Problem? Mathematics and physics? I remember you told Mr. Yang that you were participating in this subject?" Sun Yu was taken aback and asked.

"No, that subject is over, now it's about materials science."

"... Has physics been unable to stop you from growing old?"

"Interested."

"...Sure enough, I shouldn't have asked."

Sun Yu gave up the conversation with Lin Xiao, and then said: "My girlfriend and I continued to go shopping, you continue to shine for our mathematics community."

Lin Xiao said with a smile: "Go ahead, I won't bother you. By the way, Yu Man, you have to keep an eye on him. This guy used to share videos of beautiful women with us."

After speaking, he turned his head and left.

"Damn, you slandered me! Manman, don't listen to him, he slandered me!"

"Just let me see your video browsing history."

"Ah this..."

……

Lin Xiao, who had already walked away, snorted and showed me his girlfriend, right?
let you show.

It's better to go home and pet the cat.

Thinking of this, Lin Xiao planned to go back.

However, everyone probably thought that today was a time, and not long after, Lin Xiao met another acquaintance.

Kong Huaan.

It was the roommate that Lin Xiao met when he participated in the National Mathematics Training Team.

Especially his family has a courtyard house in Shangjing.

Kong Huaan was studying computer science at Peking University, and the two of them had met twice after they enrolled, but after that, Kong Huaan acted busier than him, and there was no one at all.

It was rare to see her once today, so Lin Xiao smiled and said, "Hey, Kong Huaan, you also have time to go out for a stroll."

Kong Huaan was also surprised when he saw Lin Xiao, but probably because his taciturn character hadn't improved, he just nodded and said, "Well, a project is completed, let's go out for a walk."

"Have you started working on a project with your mentor? Not bad."

Lin Xiao nodded. Kong Huaan had never touched a computer before, and it has been less than a year now, and he is able to do projects with his mentor. It seems that he is quite talented.

But he didn't know that Kong Huaan said next, "It's my own project."

Lin Xiao was stunned: "Your own project?"

"Yes." Kong Hua'an nodded, "I received a program outsourced by Xunfei."

He smiled: "I made tens of thousands of dollars, it's the first time I've made money."

Lin Xiao gave a thumbs up, "Nice."

It seems that Kong Huaan has also found his comfort zone.

He may not have shown such an outstanding talent in mathematics, but now he is not a genius in computers.

It is amazing to receive an outsourcing project from a big company like Xunfei in just one year.

"Then keep going, maybe you will be the future computer leader of Huaguo."

Kong Huaan smiled: "You are now the leader of the world's mathematics community."

Lin Xiao smiled and waved his hands: "Leaders in the mathematics field dare not say that there are quite a lot of bigwigs in mathematics."

"Ah."

Kong Huaan nodded without saying anything. Suddenly he said, "By the way, I made a hacker-proof software. Do you want to use it?"

"Anti-hacking software?"

Lin Xiao thought for a while and said, "Okay, you can send it to me for a try."

Kong Huaan showed a smile on his face: "Okay."

　There should be another chapter later.

　　[The tutor said that the draft can be finalized, and the normal update will resume in two days]
