I Am Just a Support Teacher

Yang Xin went to the Industrial and Commercial Bureau, signed some documents, and successfully turned the Dream Scholarship into a charity organization.

When Yang Xin finished dealing with everything, it was only half a month before the Chinese New Year.

At this moment, he went to the capital to participate in the award ceremony of the top ten outstanding youths in the country.

"Teacher! Here I come."

After finally coming to the capital, Yang Xin naturally wants to meet some students who have not returned to the capital.

Such as Tian Jiajia, Zhou Qian, Liu Zichen and others.

The meeting place was in a courtyard house that He Qingqing bought in the capital.

Because He Qingqing often came to the capital for business trips, she simply bought a courtyard house in the capital.

The quadrangle courtyard was very large, and Yang Xin invited more than a dozen students who were still in the capital to come over this day.

Faced with Yang Xin's invitation, almost all the students came.

The only thing that surprised Yang Xin was that Zhao Zihan, who was studying in the Northeast, was also in the capital.

Among Yang Xin's students, some have graduated for three or four years, such as Zhou Qian and Liu Zichen, who graduated in 2026.

There are also those who graduated only two or three years ago, such as Zhao Zihan and Wang Lingni.

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

When Yang Xin gathered these students together, he naturally asked about their academic situation.

At present, both Zhou Qian and Liu Zichen have graduated with Ph.D., and Wang Lingni and Luo Yuxuan are also about to graduate.

But Zhao Zihan, what Yang Xin didn't expect was that she had already graduated.

The graduates under Yang Xin's command all studied intensively in various majors. For example, Zhou Qian and Li Kexin majored in materials physics, and Liu Zichen majored in materials chemistry.

Zhao Zihan is an aircraft design major.

Zhang Yuheng majored in aircraft power engineering, specializing in the study of aero engines.

And Zhang Yuechi,

It's an avionics major, and so on and so on.

This class reunion in the capital is considered a class reunion, after all, all the students used to be students of Yang Xin.

In this class reunion, the most dazzling one is undoubtedly Tian Jiajia.

Tian Jiajia has already stood at the top of all the brothers and sisters with her own strength.

What she has achieved is an existence that everyone should look up to.

Of course, Tian Jiajia also behaved very easy-going, and did not look down on the younger brothers and sisters just because of her achievements.

"Zhao Zihan, where are you going to work after you graduate with a Ph.D?" Tian Jiajia asked Zhao Zihan.

"Of course I went to the Chengfei Research Institute, which was arranged by my mentor." Zhao Zihan said.

The mentor she mentioned was naturally the famous Academician Yang Wei.

"Congratulations, I hope you can contribute to the research and development of our country's sixth-generation aircraft." Tian Jiajia said to Zhao Zihan.

"Yes, I will." Zhao Zihan nodded.

"Brother Zhang Yuheng, I heard that you designed an airplane model engine last year and beat all the contestants to win the first place?" Tian Jiajia asked Zhang Yuheng again.

"Hey, yes, it's just a small fight, nothing to worry about." Zhang Yuheng said hey.

On the other side, seeing all the students chatting happily, Yang Xin showed a satisfied smile at the corner of his mouth.

These students of his have a bright future, which is the most gratifying thing for a teacher.

"Zhang Yuheng, you study aircraft engines, do you know why our country's aircraft engines are not as good as foreign ones?" Zhao Zihan asked Zhang Yuheng.

"Of course I know." Zhang Yuheng said: "The reason why our country's aero engines are backward is not because our country can't design advanced engines, but mainly because our country is too far behind in terms of materials."

Zhang Yuheng said: "For example, the high-temperature-resistant materials needed in the engine, the high-temperature-resistant materials used in American aero-engines can work at a high temperature of 1,600 degrees for a long time without deformation, while the high-temperature-resistant materials in our country can only reach 1,100 degrees."

"In order to prevent this material, which can only withstand high temperatures of 1100 degrees, from being damaged by high temperatures, our scientists had to design a very complicated cooling system in the structure of the aero-engine."

"For example, the cooling channels like a labyrinth, and tens of thousands of tiny cooling holes, are all designed to allow high temperature resistant materials to work properly."

"At the same time, this also brings great challenges to the design, manufacture and testing of aero-engines, making my country's aero-engines always inferior to those of Western countries."

"If we can also have a material that can withstand high temperatures above 1600, like the United States, then our country's aero-engines can get rid of many unnecessary designs, and we can make a huge breakthrough in our country's engine technology."

Hearing Zhang Yuheng's words, many people were thoughtful.

Tian Jiajia doesn't know much about aviation, but she said with some doubts: "I remember that our country seems to have materials that can withstand 3,000 to 4,000 degrees, right? It has been reported on the Internet."

Hearing Tian Jiajia's Hua, Zhang Yuheng said with a smile: "Sister Jiajia, this is different. Not all high-temperature-resistant materials can be used in aero-engines, such as tungsten metal, whose melting point reaches 3422 degrees, but It is not suitable as an aero-engine material."

"Aviation materials, in addition to its high temperature resistance, also depends on its strength, toughness, corrosion resistance, oxidation resistance, etc. must meet certain standards."

"Oh! That's right!" Hearing Zhang Yuheng's words, Tian Jiajia nodded in understanding.

"Aeroengines are known as the jewel in the crown of industry. Aeroengines can usually reflect the highest industrial level of a country. Compared with the United States, our country is still weaker." Zhang Yueheng said.

Hearing Zhang Yuheng's words, Li Kexin on the side said to him: "Brother Zhang Yuheng, I'm going to study high-temperature-resistant aviation metal materials soon, and the teacher also promised to invest at least 500 million in me. As a student majoring in aircraft power, do you have any questions?" Good advice for me?"

Hearing Li Kexin's words, Zhang Yuheng looked at her in surprise, and said, "Senior Sister Kexin, are you serious?"

"Of course it's true. Why did I lie to you? If you don't believe me, just ask the teacher." Li Kexin said, and pouted towards Yang Xin after speaking.

"Teacher, you really promised to invest 500 million yuan in the research of high-temperature resistant materials for Senior Sister Kexin?" Zhang Yuheng asked Yang Xin in surprise.

Hearing Zhang Yuheng's words, Yang Xin nodded and replied: "Yes, this is just the previous investment, if it is not enough, you can add more."

"Here, many laboratories in our country are researching high-temperature-resistant aviation materials. The country invests tens of billions of yuan in this every year, but I have never heard of anyone who can research it. Your investment is only 500 million. Sister Xin, research, are you sure this will work?" Zhang Yuhengchang Yang Xin said.
