Rebirth of science and technology academic master

Chapter 198 The experiment was successful

From being an expert and a professor to being an expert, it is hard for people to believe that some of the weird remarks actually come from highly educated intellectuals, and they are said without thinking.

In the past ten years or so, after being baptized by weird remarks again and again, the people's eyes have finally become sharp, and they have slowly seen through the true nature of this group of people, and swept them into the ranks of "people who call themselves beasts".

Many people thought that China would always be immersed in weird remarks, but facts have proved that China has its own national conditions, and it is not possible to change China with weird remarks.

Qin Yuanqing hated this group of people very much and wanted to sweep them all into the garbage heap of history.

Every time Qin Yuanqing talks about this in a public class, he will remind people to look at this group of people with sharp eyes. Time will prove that this group of people will be swept into the garbage heap of history.

However, after the conference ended, Qin Yuanqing did not have time to watch "The Legend of Zhen Huan" with Jing Tian, ​​but went directly to the 404 Steel Plant.

Because the sample has been manufactured and tested, the test result is 100°C lower than the theory, only 1750°C~1800°C.

The maximum temperature that turbine blades can withstand is an important technical indicator of turbine engine technology.

Ordinary turbine engine blades also need to withstand high temperatures above 700°C, and most turbine blades are made of nickel-iron alloy. Depending on the alloy formula, the melting point of nickel-iron alloy will fluctuate to a certain extent, and the fluctuation will be around 950°C.

Aviation turbine engines have higher requirements. The higher the temperature that the turbine blades can withstand, the better. The temperature that the turbine blades can withstand is directly related to the maximum thrust that the engine can produce.

Although today's 1750℃~1800℃ has far exceeded the high temperature resistance of domestic aviation materials today, it shocked the entire 404 steel factory. After all, those who work on high-temperature-resistant materials know that at the current stage of development, high-temperature-resistant materials are calculated based on K increase, and every 1°C increase is not easy.

But Qin Yuanqing knew that there must be a problem in some link, otherwise it would not be 100°C lower than the theoretical value.

Don’t underestimate 100°C. According to international empirical formulas, if the design level of the engine turbine and fan is the same, for every 100°C increase in the turbine front temperature, the maximum thrust can increase by 15%.

It is conceivable that if the temperature difference is 100℃, the aeroengine produced by then will not be as good as the F119 aeroengine!

If you want to build, build the best!

This has always been Qin Yuanqing's philosophy, otherwise why would he spend so much money to exchange for the F119 aero engine.

After arriving at the 404 Steel Plant, after a series of inspections, Qin Yuanqing was taken into a laboratory by the project team. First, Qin Yuanqing looked at a series of reports. The report was a thick one, which was recorded and summarized by the R\u0026D personnel during the entire experiment.

Qin Yuanqing read the report and found that there were basically no problems. This made Qin Yuanqing frown slightly and looked at Academician Liu: "Did you personally check the samples when they were made?"

"Academician Qin, our 404 steel factory can be said to be the most advanced manufacturing plant in the country. We are responsible for the manufacturing of many large-scale military industries, and the workers are very experienced. Please rest assured!" Zhao Zhenhua said quickly.

Qin Yuanqing suddenly understood, and then said: "Please cooperate with the 404 steel factory and make a batch of samples again. I will watch it with my own eyes!"

Zhao Zhenhua is also a human being, so he still doesn't understand. Qin Yuanqing is questioning the standardization of the 404 steel factory, and his face suddenly looks ugly.

However, Zhao Zhenhua also knew from Academician Liu that the material was developed by Qin Yuanqing, which meant that Qin Yuanqing was also a materials expert, and Qin Yuanqing was also the general person in charge. The superior leaders directly called the 404 Steel Factory and asked the 404 Steel Factory to cooperate.

So Zhao Zhenhua had to have someone recast the sample, and Qin Yuanqing took the project team to watch it in person. For such complex materials, the equipment used was very advanced.

However, Qin Yuanqing soon discovered a problem. Although the quantities were still the same, the order of input was wrong, and the temperature controlled for the casting samples was also wrong.

Qin Yuanqing asked a bunch of questions on the spot, which made the relevant person in charge of the 404 Steel Plant blush and had to cast another batch of samples.

Five batches of samples were cast before and after the requirements of Qin Yuanqing were met.

Academician Liu and the 404 Steel Factory also conducted tests on the samples, and the result was that the melting points of this batch of samples showed an increasing trend.

The melting point of the last batch of samples reached 1900℃~1950℃!

It is 50℃ higher than the theoretical value!

Suddenly the entire project team was in a sensation and couldn't help but burst into warm applause. After all, this was a breakthrough and it also meant that the formula was completely feasible.

Zhao Zhenhua was also excited. Although this was not developed by their aviation materials team, after all, as a cooperating unit and a personal participant, it was also an honor to see domestic aviation engine materials achieve a great leap forward.

"Academician Liu, remember to keep this report confidential and not make it public!" Qin Yuanqing warned.

"Do you need to report to your superiors!?" Academician Liu hesitated for a moment.

Qin Yuanqing nodded slightly: "Report it! The further verification and acceptance will be left to you!"

Qin Yuanqing, who has been working in the 404 steel plant for some time, has no intention of staying in the 404 steel plant after solving the problem.

The success of this experiment does not mean that it has reached the end, but it requires further verification and the collection of more data. Only when each verification is stable does it mean complete mastery. For such important results, the higher-level department will organize an expert group to accept them.

Although the funding for the Aero Engine Research Institute does not yet come from the state, theoretically the patents belong to the research institute and do not require expert acceptance. However, in China, given China's national conditions, the superior jurisdiction is very strong, and it cannot be applied without acceptance.

Qin Yuanqing can count on obtaining profits from patent authorization in the future, so that the Aero Engine Research Institute can realize its self-hematopoietic function.

Many domestic research institutions are lifeless because they rely solely on funding from superiors, and their own research output does not bring in revenue and has no hematopoietic function. Once funding from superiors is reduced, even salary payment will immediately become a problem.

. . . . . .

Soon, the superior department received the news and was immediately shocked.

After all, aviation engines are related to the entire national defense security. At present, domestic aviation engines are still mainly imported. However, this kind of heart disease can be fatal if it occurs at a critical moment. This is simply unacceptable.

But the country also knows that too much homework has been missed in the past, and now it is the make-up stage. All we can do is wait and wait patiently.

Basic scientific research cannot be solved by working overtime and public relations. It must be down-to-earth and move forward step by step.

As a result, we have now received a joint report from Shuimu University Aero Engine Research Institute and 404 Steel Factory. The high-temperature resistant materials for aero engines have been solved. Isn't this just a big satellite?

Immediately, several departments formed a joint acceptance group. The standards of the acceptance group were very high. The people who could enter the acceptance group were at least outstanding scientists who were outstanding scientists in the field of materials!

"Chichi~~~ You really play the piano randomly, you can fly across it all at once, and you are not afraid of falling to death! You even dare to fake this, you are so courageous!" The acceptance team set off in a mighty manner, and one of them was a gray-haired old expert. He scoffed: "The Aero Engine Research Institute has only been established for a short time. In less than a year, it is said that a breakthrough has been made, and it is a leaping breakthrough."

"I know that the director of the Aero Engine Research Institute is a young man, and he is still engaged in mathematics research and automobile research. Alas, he really has a hairless mouth and a weak tongue! Young people are eager for quick success and quick gains, and they are too impetuous!"

Not many in the acceptance team are willing to believe it. This is really unbelievable. Damn it, everyone is in the industry. No one knows how much each other weighs. Is this a basic field that you can break through if you want to?

Play the piano randomly!

"Lao Li, do you think this is reliable? Your happiness will not be in vain, right?" An old man of about sixty years old lowered his voice and said to a man of about the same age sitting next to him: "Why do I always feel seventy in my heart?" Up or down?"

"Old Zhao, I have already called and confirmed with 404 Steel Factory. The director of 404 Steel Factory is my college classmate. We are bunk beds, so everything is safe!" Old Li smiled mysteriously.

Although the two of them belong to different units, they often interact with each other and are acquaintances with each other.

"Our academician Qin is really incredible. He is a genius to the extreme. He is a genius. I even went to attend the inauguration of the Aero Engine Research Institute. As a result, a big satellite has been launched now. Once the acceptance is completed, the big leaders will definitely carry out the inspection." To praise him, he might even visit the Aero Engine Research Institute!" Lao Li said with emotion.

With acquaintances, he is not like others who don't believe or doubt, but have already confirmed it. This is the advantage of having acquaintances, it is easier to do things and well-informed.

"We all know that aero engines are a heart disease in our aviation field. Solving this heart disease is definitely a great contribution to the country. No praise can be exaggerated!" Lao Zhao said: "Academician Qin previously solved the core problem in the automotive field. Technology, it solved the core technology of smartphones last year, and if it solves the heart disease of aerospace engines this year, I think it would be normal to award the highest award to him in an exceptional way!"

"You make sense!" Lao Li nodded and said, "It's really annoying when you say that people are comparing themselves to each other. My son is studying for a Ph.D., but he hasn't even finished his Ph.D. thesis yet. Academician Qin is several years younger than him. What a great achievement!”

Comparing people with others is infuriating, so you have to throw away the goods!

Every time Lao Li saw his son, he couldn't help but use Qin Yuanqing to flog him. He hoped that even if his son was not as good as Qin Yuanqing, he would be one-tenth as good as Qin Yuanqing.

It turned out that he was already in his third year as a Ph.D. student and had not even completed his doctoral thesis. He was so angry that Lao Li almost had a heart attack.
