Hearing Lin Xiao's question, Chen Bao couldn't help but laugh.
The material he is expected to study in this project is its application on engine wall panels.
Especially fighter engines.
Fighter engines are generally small bypass ratio engines, unlike civil aviation engines which are large bypass ratio engines. The requirements for high temperature resistance of materials for large bypass ratio engines are not as high as those for small bypass ratio engines.
In fighter jets, the service temperature of the engine wall panels is generally around 600°C, sometimes even higher. At the same time, the main stresses they bear come from mechanical loads and high-frequency vibrations.
As for the service temperature of the fan blades, it is as high as over 1,000 degrees Celsius, which is almost the hottest part of the entire engine. Moreover, the rotation speed of the fan blades is quite fast, which brings more complex stresses. This is enough to show that the fan blades have to endure
How bad the environment is.
For engines, there is an important indicator, which is the temperature in front of the vortex.
Generally speaking, for every 100K increase in the vortex front temperature, the engine thrust can be increased by at least 10%, and may even be increased by more than 20%.
Therefore, the higher the high temperature resistance of the fan blade, the higher the temperature in front of the vortex.
How to keep the fan blades strong at such high temperatures is a challenge for materials researchers around the world.
Therefore, the blades of aerospace engines are the most difficult materials to prepare and develop. Their requirements for high temperature, pressure, and strength make them known as the crown jewel of the industry.
Lin Xiao said that he wanted to improve the creep resistance of their material by 100%, which is completely fantastic. If the creep resistance is improved by 100%, the high-temperature structural strength of the material will definitely be improved accordingly.
Well, other performance can also be improved, right?
Doesn’t this mean heading straight towards the material of the fan blade?
In that case, they would have to conduct more and more complicated experiments, which would take an unknown amount of time, and they might not be successful in the end.
For Chen Bao, he has developed in this area before, but finally 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. If he has not been successful, even if he is above
If you are willing to provide resources and support all the time, who can guarantee that no one else will say bad things?
It’s not like 60 years ago when the whole country worked together to make mushroom eggs.
Hearing Chen Bao's words, Lin Xiao smiled: "I'll just ask."
Chen Bao shook his head: "Titanium-aluminum alloy may have this potential, but our direction is definitely wrong. This needs to start from the atomic arrangement structure. There are opportunities to consider the development of single crystal directional solidification, but then the funds I want to apply for may be
There will be two or three more zeros at the end.”
Their research funding for this topic is several million. If two or three zeros are added to this, it will be in the nine or ten digits.
However, the development cost of any fighter engine is not a matter of hundreds of millions, but tens of billions. As the core component of the fan blade material, the research and development cost is hundreds of millions or billions.
Accident.
After hearing Chen Bao's words, some graduate students around asked: "Boss, in the projects you have participated in before, which one has invested the most?"
Chen Bao said with a smile: "I have also participated in the C919, J-35, and J-20. I have participated in the research on materials. These are large projects worth tens of billions."
"Wow!"
For a moment, all the graduate students present showed expressions of admiration.
This is an academician of materials science!
"Okay, stop talking. That's it. Don't mention the bravery of a hero. Let's continue our research."
Chen Bao waved his hands, looking like he was just a fool.
Hearing what Chen Bao said, everyone else nodded and began to continue their work.
Lin Xiao, on the other hand, looked at what was 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: "Okay."
Lin Xiao nodded slightly, that's fine.
Since it can be folded in when answering questions with more than 30 truth points, he can now add 14.2 more truth points to obtain a model of this new material.
However, there is no rush in this matter. He can study it first. When he achieves certain results, that is, when the absolute distance between him and his final goal is shortened, he can then use truth points to purchase it. He may be able to save some by then.
point of truth.
So he smiled slightly and said: "Academician Chen, let's try it now, titanium 7 aluminum 8 zirconium 1?"
"Well, let's try it here now."
Chen Bao responded.
Subsequently, the second stage of computational simulation began.
…
Time passed quickly, and it was another ten days.
As we enter April, the temperature gradually warms up, and the weather around 20 degrees is exactly the most suitable temperature.
Because they had identified a new material, they once again entered the process of designing the production process of the new material. Lin Xiao had nothing to do, so he came to the campus of Beijing University to enjoy the breath of spring.
"Well, I haven't had such comfortable sunshine in a long time."
Walking by the Weiming Lake, bathing in the sunshine, Lin Xiao squinted his eyes comfortably. It was a pity that he didn't bring Mimi over. Otherwise, it would have been very comfortable to sit on the lawn and pet a ragdoll cat.
Suddenly, he felt someone pat him on the back. When he turned around, surprise appeared on his face: "Hey, Sun Yu, I haven't seen you for a long time."
Sun Yu said speechlessly: "I should be saying this to you, right? I can actually see you in the school. It seems that you haven't forgotten that you are a Jing-sama?"
Lin Xiao shrugged: "The college allows me not to attend classes, so of course I won't attend."
Sun Yu couldn't help complaining: "You are outrageous. You don't even attend a single class. Even if you get full marks in math subjects, you can also get full marks in thinking. I don't know how you learn. Good guy, you got a straight 4.0."
Point, we are number one in the entire department.”
Lin Xiao laughed and said: "If you include my paper proving Goldbach's conjecture, it should be more than 4.0."
Sun Yu: "...You are awesome."
It's still a familiar recipe, a familiar taste, Lin Shen started to show off again.
At this time, a pretty girl came to Sun Yu.
When Sun Yu saw this girl coming, he put his arm 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 the 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 difficult to find a girlfriend. The main thing is to be attentive. You have to be good at discovering and then use your knowledge to conquer her, right? 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 God Lin to find a girlfriend. The girls in our physics academy often talk about you. If you want to find a girlfriend,
Girlfriend, tell me, I will greet them directly."
"No, no, no." Lin Xiao waved his hand.
Sun Yu laughed and said: "Lin Shen 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?
How can we not find a girlfriend for being so handsome?
"By the way, Lin Shen, do you want to form another team? Let's participate in the Qiu Chengtong Mathematics Competition. We will have a solid subject."
At this time Sun Yu asked.
Lin Xiao waved his hand: "I won't go, I'm participating in a project recently."
"Project? Mathematical physics? I remember you told Mr. Yang that you were participating in a project in this area?" Sun Yu was stunned and asked.
"No, that topic is over. Now it's about materials science."
"...Physics can no longer stop you from getting older?"
"It's out of interest."
"...Sure enough, I shouldn't have asked."
Sun Yu gave up the conversation with Lin Xiao and then said: "My girlfriend and I will continue to go shopping. You can continue to shine for our mathematical community."
Lin Xiao said with a smile: "Go ahead, I won't disturb you anymore. By the way, Yu Man, you have to take good care of him. This guy used to often share videos of beautiful women with us."
Lin Xiao, who had already walked away, hummed and smiled, "You want to show off your girlfriend to me, right?"
Let you show off.
Might as well go home and pet the cat.
With this thought, Lin Xiao planned to go back.
However, everyone probably thought that today was the same time. Not long after, Lin Xiao met another acquaintance.
Kong Huaan.
That was the roommate Lin Xiao met when he participated in the national mathematics training team.
In particular, his family has a courtyard house in Shangjing.
Kong Huaan was studying computer science at Beijing University. They met twice after they entered school, but after that, Kong Huaan acted busier than him and was completely nowhere to be seen.
It was a rare meeting today, so Lin Xiao smiled and said: "Hey, Kong Hua'an, you also have time to go out and hang out."
Kong Huaan was also surprised when he saw Lin Xiao, but probably because his previously taciturn character had not 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? It's not bad."
Lin Xiao nodded. Kong Huaan had never touched a computer before, and now, less than a year later, he was able to work on projects with his tutor. It seemed that his talent was quite good.
But little did he know that Kong Huaan would say 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 my first time making money."
Lin Xiao gave a thumbs up, "Awesome."
It seems that Kong Huaan has also found his comfort zone.
He may not have shown much talent in mathematics, but now he is a genius in computers.
It is really amazing to receive an outsourcing project from a large company like Xunfei in just one year.
"Then keep working hard, maybe you will be the future leader of computers in China."
Kong Huaan smiled: "You are now a leader in the world of mathematics."
Lin Xiao smiled and waved his hand: "Leaders in mathematics dare not say that. There are still many big names in mathematics."
"Um."
Kong Huaan nodded without saying anything. Suddenly he said: "By the way, I made a software to prevent hacker attacks. Do you want to use it?"
“Software to prevent hackers?”
Lin Xiao thought for a while and said, "Okay, you can send it to me for a try when the time comes."
A smile appeared on Kong Huaan's face: "Okay."
There should be another chapter later.
[The instructor said that the draft can be finalized and normal updates will resume in two days]
