I'm just a support teacher

Yang Xin went to the Industry and Commerce Bureau, signed some documents, and turned the dream scholarship into a charity.

When Yang Xin has handled all things, it is only half a month.

Just then, he went to the top ten outstanding awards ceremony of the top ten outstanding young people.

"Teacher! I am coming."

It's hard to come to the capital, Yang Xin naturally wants to see some students who have not returned in the capital.

For example, Tian Jiajia, Zhou Qian, Liu Wei Chen and others.

The location of the meeting is in a set of four-in-courts bought in He Qingqing.

He Qingqing because he often comes to the capital, so I bought a set of four-in-one hospital in the capital.

The courtyard is very large. This day Yang Xin invited more than a dozen students in the capital.

In the face of Yang Xin's invitation, almost all students are coming.

Just let Yang Xin, Zhao Zihan reading in Northeast is also in the capital.

Among these students of Yangxin, some have been graduated for three or four years. For example, Zhou Qian and Liu Yichen are graduated in 2026.

There are also two or three years of graduation, such as Zhao Zihan Wang Lingni, and so on.

In addition, there are some students who graduated last year.

Yang Xin got together these students, nature is to ask their academic conditions.

At present, Zhou Qian and Liu Wei Chen have graduated, Wang Lingni and Luo Yuxuan and others, and graduated.

It is Zhao Zihan, let Yang Xuan have never thought of she has graduated.

These students graduated from Yang Xin's hand, all of them are in various majors, such as Zhou Qian, and Li Kexin, is the physical and physical professional, Liu Wei is a material chemistry.

Zhao Zihan is the aircraft design.

Zhang Yutheng is a major of the aircraft power engineering, specializing in air engine.

There is also Zhang Yuechi, which is an avant-saving major, and so on.

This time, at the capital gathering, it is a classmate party. After all, all students have been a student of Yangxin.

In this classmate party, the most dazzling is undoubtedly Tian Jiajia.

Tian Jiajia has stood the top of all the teacher's brothers and sisters with their own strength.

What she has achieved is that everyone has to look up.

Of course, Tian Jiajia also made it very followed, and did not see the teacher's sister because of his achievements.

"Zhao Zihan graduated from your doctor, where is it going to work?" Tian Jiajia Zhao Zihan asked.

"Of course, I am going to Cheng Fei Institute, I am arranged by my mentor." Zhao Zihan said.

What she said, natural is a famous Yangwei academician.

"Congratulations, I hope you can contribute to the development of the six generations of our country." Tian Jiajia Zhao Zihan said.

"Well, I will." Zhao Zihan nodded.

"Zhang Yuxheng brother, I heard that you design a aircraft model engine last year, defeating all the contestants got the first?" Tian Jiajia also asked Zhang Yutheng.

"Oh, yes, it's just a small trick, no enough to do." Zhang Yuxheng said.

On the other hand, I looked at all students, I was happy, and Yang Xinfei said with a satisfactory smile.

His students have a good future, which is the most gratified as a teacher.

"Zhang Yutheng, you study aircraft engine, do you know why my country's aircraft engine is not abroad?" Zhao Zihan asked Zhang Yutheng.

"Of course I know." Zhang Yutheng said: "The reason why our country's aviation engine is not because our country does not design the advanced engine, mainly because our country has too much in terms of materials."

Zhang Yutheng said: "For such as high temperature resistance materials required in the engine, the high temperature resistant material used by the aviation engine can operate in a high temperature of 1600 degrees for a long time, and the high temperature resistant material of our country can only reach 1100 degrees."

"In order to make this material that can only be resistant to 1100 degrees of high temperature is not destroyed by high temperature, our scientists have to design a very complex cooling system in the aerospace engine structure."

"This is like a labyrinth, as well as a fine cooling small hole processed, these are designed to make the high temperature resistance of high temperature resistance."

"At the same time, this also brings great challenges to the design, manufacturing and trial of the air engine, making our aviation engine are not as good as Western countries."

"If we can also have a material that is high temperature than 1600, then the aviation engine in our country can abandon many unwanted designs, and can make our engine technology great breakthrough."

When I heard Zhang Yuxheng, many people are thinking.

Tian Jiajia did not understand what aviation, but she had some doubts: "I remember that our country seems to have a material that can resist three or four thousand degrees?"

I heard Tian Jiajia's Hua, Zhang Yuheng said: "Jia Jiajie, this is not the same, not all high temperature resistance materials can be used above the aviation engine, such as tungsten metal, his melting point has reached 3422 degrees, but It is not suitable as a material as an air engine. "

"Aviation material, in addition to watching his high temperature, it depends on its intensity, toughness, corrosion, antioxidant, etc., and must have reached a certain standard."

"Oh! It's this!" When I heard Zhang Yuxheng, Tian Jiajia nodded to understand.

"Aviation engine is called the Pearl of Industrial Crown, aerospace engine, usually reflects the highest industrial level of a country, compared with the country, but also weaken." Zhang Yueheng said.

When I heard Zhang Yuxi, Li Kexin, said: "Zhang Yuxheng teacher, I will prepare for high temperature air metal materials immediately, the teacher also promised to invest 50 million to invest five billions, you as a driving professional student, there is anything Good suggestion give me? "

When I heard Li Kexin, Zhang Yutheng looked at her, then said: "Can I wish you said, do you say true?"

"Of course, I really do, I don't believe you ask the teacher to know." Li Kexin said, finishing Yang Xin, Nuji.

"Teacher, you really promised to invest five billion to study high temperature materials?" Zhang Yutheng asked Yang.

When I heard Zhang Yuxheng, Yang Xin nodded and said: "Yes, this is just the investment in front. If it is not enough, you can also append."

"This, many laboratory in our country are studying high-temperature air materials. The country has invested tens of millions of billions per year, but they have not heard who can study, you invest five billions, or let I have a study, can you determine this way? "Zhang Yutheng said.
