From all-round academic master to chief scientist - Chapter 153 Verification using supercomputer!

Finally, Chen Bao couldn’t help but want to ask Lin Xiao.

So he spoke out again: “Lin Xiao, what are you doing?”

Hearing the sound at such a close distance, Lin Xiao finally came back to his senses, turned his head and took a look, and said in surprise: “Academician Chen, you are here.”

Chen Bao didn’t talk nonsense and asked directly: “Let’s not talk about this for now. First, tell me, what material are you simulating now? This shouldn’t be the material of the siding, right?”

Hearing Chen Bao’s question, Lin Xiao couldn’t help but admire the academician’s knowledge. He could tell at a glance that the material he made was not for siding. Although Huang Haoran noticed that his material was a little different a few days ago, he didn’t see it. It is no longer made of siding material.

He nodded and said with a smile: “Yes, this is not the material of the siding, but the material of the turbine fan blades.”

“Aren’t you going to make siding materials? How to make this material?”

“I just gave it a try.” Lin Xiao responded.

Before Chen Bao could speak, Cao Zhong beside him couldn’t help but said: “What? You said this is the material of fan blades? Turbine fan blades?”

Looking at this person, Lin Xiao didn’t recognize him, but he might be an academician together with Academician Chen.

He nodded and said: “Yes, it is the material used on turbine fan blades, using directional solidification technology to strengthen its one-way mechanical properties. In addition, its mechanical strength is also very strong. In addition, titanium-aluminum alloy has strong anti-oxidation and anti-fatigue properties. As long as this material is prepared, it will definitely bring us surprises.”

Hearing Lin Xiao’s confident words, Cao Zhong and Chen Bao both looked at each other.

Although the calculation results were surprising, after they came to their senses at this time, they still did not think that Lin Xiao could so easily come up with a material that could be used as a turbine fan blade.

People don’t know how much money it would cost to research this kind of material. Even if they spend hundreds of millions or billions of money, they may not be able to get it out. You can just get one now, who would believe it!

Finally, Chen Bao said: “Although the calculation results of the software are very good, it is also likely to be a calculation error. Lin Xiao, you should also know that even a small error in the materials used on the turbine fan blades will cause There’s a huge gap.”

A small error can sometimes be fatal to a precision machine like an aerospace engine.

Hearing Chen Bao’s words, Lin Xiao didn’t say anything, but opened various other software and showed his calculation results to the two of them one by one.

At this time, both Chen Bao and Cao Zhong fell silent.

Lin Xiao actually performed calculations on so many software, and the calculation results of most software showed that this material has extremely strong performance. According to the different algorithms between software, the calculation results have some errors, so among them A few software even believe that this new material is stronger than the blade material currently used on the turbofan 15.

This left neither of them knowing how to refute.

Computational materials science has developed to this point. Although it is still limited to theoretical results rather than factual results such as experiments, there is no doubt that it has certain “guidance”.

What if, just what if, Lin Xiao’s experiment is carried out, theirs can really succeed?

After all, it’s not like I haven’t succeeded before.

The breathing of the two academicians could not help but become rapid at this moment.

A material that is suitable for turbine fan blades!

No matter what, it’s worth a try, right?

But now, there is another embarrassing thing.

Chen Bao said: “We have no money. I am not an expert in directional solidification technology, and the design of the directional solidification process is a bit too expensive.”

Lin Xiao was stunned, no money?

This is indeed a big problem.

He couldn’t help but show helplessness on his face. It wasn’t a penny that stumped the heroic man. This time, it was millions or tens of millions of money that stumped the heroic man.

However, at this time, Cao Zhong said: “I can ask the group to invest more money in you, or set up a separate research group to come up with this material.”

Hearing Cao Zhong’s words, Lin Xiao was startled again and couldn’t help but look at him in surprise. Can this person control the Aviation Development Group?

When Cao Zhong saw Lin Xiao looking at him in surprise, a smile appeared on his face and he said, “I forgot to introduce it to Lin Xiao. I am Cao Zhong from the Aviation Development Group, an academician of the Academy of Engineering, and I study aerospace engines.”

Chen Bao patted Cao Zhong with a smile and said to Lin Xiao: “Academician Cao and I are old friends. We are both our own people. He is also the deputy general manager of the Aviation Development Group. There is no problem in asking for funds.”

Lin Xiao was suddenly pleasantly surprised, “Thank you, Academician Cao!”

“What’s the point of thanking you for this? We are all doing it for our national defense!”

Cao Zhong said with a smile. Suddenly he remembered something and said, “By the way, Lin Xiao, have you ever told anyone about this matter?”

“That’s not true.” Lin Xiao shook his head.

“That’s good.” Cao Zhong said to Lin Xiao with a solemn expression on his face: “You also know that our country is not facing a particularly peaceful situation internationally, so in order to protect our military secrets and to protect yourself, If this material can really achieve the expected results after it is finally prepared, then it will definitely become our confidential technology and no disclosure, including your contribution to it, can be made. Can you understand this?”

Hearing Cao Zhong’s serious words, Lin Xiao nodded heavily and said, “I know, I won’t tell anyone.”

In fact, he had already been prepared for this kind of thing, so he didn’t answer when Huang Haoran asked him before. Similarly, he didn’t perform simulation calculations on his personal computer. After all, he couldn’t guarantee that his computer Safe or not.

Seeing Lin Xiao nodding, Cao Zhong showed a smile on his face, patted his shoulder and said: “Okay, as long as you can succeed, this credit will definitely be recorded in your file. If the file is decrypted in the future, no one will Your contribution to this will be forgotten.”

“Well, it’s our duty to do something for the country.”

Lin Xiao responded, and at the same time he had an inexplicable feeling in his heart. In this way, could he be regarded as joining the ranks of the secret guardians?

Just like the shock and emotion in his heart when he heard the story of the father of China’s nuclear submarine.

There are also those veterans of the Long March who kept their names anonymous after they were discharged from the army. Their identities were not known until their deaths because their belongings were uncovered.

The strength of China today has a lot to do with these invisible guardians, and Lin Xiao also feels a sense of honor and glory to be able to join this ranks and become comrades with those seniors.

And his answer also made the two academicians looking at him have some different emotions in their eyes, including relief and emotion.

Finally, Cao Zhong said: “Okay, let’s not talk about this for now. Lin Xiao, you go back and write your results into a report. Then I will take these reports to meetings and try my best to secure resources for the research and development of this material.”

“Okay, I will take it out as soon as possible.” Lin Xiao nodded and said: “Oh, by the way, actually, I think if we use a supercomputer to perform calculations again, it may be able to provide more powerful proof of the theoretical results.”

“Super computing?”

The two academicians were stunned.

“To use supercomputing, you have to design relevant programs. Do you know how to do this?” Chen Bao said: “Of course, if it doesn’t work, I will find someone to help you design it.”

Lin Xiao said: “I can design it myself.”

In the past few months of study, due to the needs of computational materials science, he has also made considerable progress in programming. There is no problem in designing this program.

This is why many people who originally studied computational materials science say that if they don’t achieve any results in materials science, they will directly change careers and become programmers.

After hearing Lin Xiao’s words, Chen Bao nodded and said, “Okay, that’s it. I will help you apply for supercomputing later. Our funds can still support the application for supercomputing.”

“Thank you.”

“Hey, I already told you that there is nothing to be thankful for. Let’s work hard together.” Chen Bao smiled and waved his hand.

“Um!”

Lin Xiao nodded with a smile on his face.

Even if these two academicians can spare no effort to provide help, it is also to achieve their own goals.

…

The next step is to get the report out first according to what Cao Zhong said.

Of course, since the supercomputer has not yet been used for final verification, Lin Xiao can only write down the various previous calculation results for the time being.

As for the supercomputer you applied for, it was Sunway TaihuLight.

After all, Sunway TaihuLight is developed by the state, and its safety and confidentiality are guaranteed. However, because there are many institutions applying for Sunway TaihuLight, you need to queue up and wait for about two or three weeks.

Although national institutions like them can generally jump in line, the Supercomputing Center will naturally not provide them with privileges unless they declare the importance of the project.

Of course, Lin Xiao was not in a hurry, because he applied for supercomputing for two purposes. The first purpose was to provide stronger evidence for his calculation conclusions to Cao Zhong and Chen Bao, as Cao Zhong and Chen Bao said. Using the more powerful parallel computing power of supercomputers to expand the calculation scale of this new material model, the results obtained are generally more approximate than the ordinary computers they used before.

However, this is only the first purpose, and the second purpose is based on Lin Xiao’s sensitivity to numbers, combined with his knowledge and various previous calculation results, he has a mathematical model of the material given by the system , some doubts arose.

There is a certain gap between the various properties of the titanium alloy material given by Truth Point and the theoretical properties he calculated on the computer.

The actual properties of the titanium-aluminum alloy material given by the system are much stronger than the calculated results. For example, the mechanical strength and some thermodynamic properties are much stronger.

After all, he spent so many truth points to get it done.

This also means that this new material is fully capable of withstanding higher temperatures in front of the vortex, thereby increasing the thrust of the engine.

However, this is not the most important thing. There is such a big gap between the calculation results and the actual properties, which also means that something has not been discovered.

Lin Xiao had a hunch that this was probably because there was a certain mechanism or the physical properties had not been discovered.

And he wanted to use his mathematical abilities to deduce this mechanism, and then use supercomputing to verify it!

And this is also a major role of computational materials, which is to use mathematics to explain some unexplainable things in some experiments!

Please give me a monthly pass.

There should be another chapter later.
