Rule system

The highest temperature that the turbine blade can withstand is an important indicator of turbine engine technology.

Ordinary turbine engine blades also need to withstand high temperatures above seven hundred degrees, and most of the turbine blades are all nickel-iron alloy, and the nickel iron alloy is different from the alloy formulation, and the melting point will have a certain floating, floating about 950 degrees Celsius up and down.

Aviation turbine engine requires higher requirements, the higher the temperature that the turbine blades can withstand, and the temperature that the turbine blades can be affected directly directly to the maximum thrust that the engine can occur.

For example, the F119 engine of the M country F22 fighter, the turbine temperature is about 1700 degrees Celsius, and the engine thrust is up to 15.6 tons.

The eddy current temperature of the E-AL31F engine is 1400 degrees Celsius and 12.5 tons of thrust.

The 99m1 engine assembled in the domestic high-end fighters, that is, the second batch of AL31F series engines, the temperature of 1420 degrees Celsius, the maximum thrust is 13.5 tons.

According to the international empirical formula, the engine turbine and fan design levels are the same, the turphalace temperature increases by 100 degrees Celsius, and the maximum thrust can increase by 15%.

The original K03A can withstand 1250 degrees Celsius, and the melting point has increased by one hundred degrees of casing, which has reached 1350 degrees Celsius.

This value cannot be said to catch the international advanced level, the minimum and imported high-end turbine engine is not far.

He Guilin and the entire R & D group determined that the data was excited. They talked excitedly, "" directly upgraded one hundred days! Catch up with high-end engine leaves! "

"It's not much not much!"

"I really didn't expect, in the middle of a process change, you can have such a good effect, the K03A has no progress, and now a progress is a big step! With this data, it is estimated that the project of Kunlun, Wang Hou engine, no blade problem Let's take it directly, let's make it! "

"Right, write a report, write a report!"

"Is it going to open?"

"Of course, this is a major achievement, it must be open, but I will ask the leader first ..."

The advancement of K03A has nothing to keep confidential, because it is not really superior to the international level, or is more than the imported high-end engine blade material.

307 Steel Factory R & D group excited that K03A has such a big progress, it is estimated that it is already possible to meet the needs of domestic engine, not just the problem of love - national thinking, and there is a pressure given by the higher level.

The performance of K03A has always been a problem, but also has no progress.

The Institute of Metals, Capital Air Materials Research Institute, Capital Air Materials Research Institute, are also developing the latest single crystal nickel alloys, and the results, such as DD5, DD6, melting points have exceeded 1100 degrees Celsius, the strength of the material is also very good, continue to develop Go down, it seems to replace K03a immediately.

This feels that there is no existence of the R & D group.

Although they do have no related results, everyone is still in their hearts.

It is now found that the performance of K03A has improved, or the span of up to one hundred degrees Celsius is high. They feel very easy, because in a short time, they will not have a pressure, nor is it worried about 'outside research results' The K03A will be replaced.

The staff of the steel mill returned to the office, He Guilin explained some reports, and then he immediately held an internal meeting, talked about the improvement of the K03A manufacturing process submitted by Zhao Wei. "From now, everyone is busy." Everyone is busy Get up, I will put the mission. "

"We must verify the improvement issues proposed by Zhao's academicians as soon as possible, and each item must be verified."

"This is the most important work!"

"do you understand!"

......

at the same time.

Institute of Metals in Academy of Sciences.

The team of Peng Engui led the team, and also discussed the latest outcome of the turbine blade. They developed a high-strength anti-thermal corrosion nickel-based single crystal high temperature alloy, which not only has excellent thermal corrosion performance, but also high temperature mechanical properties, good Tissue stability.

The team published the results to the domestic "Material Alloy" magazine, Peng Enguo accepted an interview with academic journalists, and sat next to several researchers and Pengneui students.

Peng Enguo sat in the most intermediate position, introduces the nickel-based single crystal high temperature alloy, "This new nickel-based alloy material, the melting point is around 1150 degrees Celsius, 50 degrees higher than DD5, it has a very good corrosion resistance, intensity Similar to DD5, it can be used for the ground and ship gas turbine high temperature components, and it can also be applied to aerospace, aerospace engine high temperature components. "

The reporter asked, "According to I know, the R & D of the single crystal nickel alloy is the air turbine blade, the new alloy material, is it used for aviation turbine blades?"

Peng Enqi thought, using a word, "infinitely close!"

He explained, "Now, for example, the Kunlun engine uses the K03A nickel iron alloy, which is the technology of more than ten years ago, there is no potential to develop."

"The strength of K03A is OK, the highest can withstand the high temperature of 1250 degrees Celsius."

"Just like you said, we study the ultimate goal of single crystal nickel alloys, that is, it is to develop a higher temperature, have higher strength alloys, which can be used for aviation engine blades. Now new nickel-based alloy can bear 1150 degrees Celsius, only one hundred celsius. "

"In the performance of the air engine turbine blade, the difference between the one hundred degrees Celsius is still very large, but I know a thing ..."

Peng Weigui said the voice is a pause. "The materials we develop have not added metal ruthenium. And many news shows that the top engine turbine blades of the M countries and E countries are containing ruthenium, metal ruthenium melting more than 3,000 degrees , Can greatly improve high temperature ability. "

Peng Enguo said very seriously, feeling like it, but in fact, even the students next to them can't help but lower, because Peng Engui said that the foreign pedestrians will be cheated, and the inner person knows if there is a problem, because There is no technology in the alloy to add metal rhenium in the alloy.

Add rhenium?

How to add it?

What is added?

These issues are not resolved, directly said that there is a good effect, pure is equal to play - stream - .

Good news is that the reporter is a foreign line. It is basically not understanding, and it will not be treated with Peng Enguei.

Peng Weigui continued to seriously, "So, the single crystal nickel alloy developed by our group, the replacement K03A has only time problems."

At this time, there was a shout next to it, "Peng Mandarin, Peng Master! Pause, suspend."

The opening is a young researcher.

Peng Engui wrinkled with brows, "Xiao Li, what's wrong? Interview, what do you say directly."

Interview with reporters also saw it.

Researchers called Xiao Li look at the reporter, and look at Peng Engui, I don't have any bad to say, I got up the small laptop next to it, and I handed the Peng Weigui said, "Peng Ming, 307 R & D group latest release According to the proposal of Zhao Wei, they improve the K03A production process and make alloy materials that can withstand 1360 degrees Celsius and higher intensity. "

"-?"

When Peng En said, he widened his eyes when he was over, and half his mouth carefully went to the computer screen.

307 Message released by the steel mill R & D group!

Suggestions for Zhao Wei Zhao Academician? Improve the production process? Manufacturing a K03A nickel iron alloy with a high temperature of 1350 degrees Celsius?

"~~~"

Peng Enguo shocked a breath.

Next to interview reporters also knew a big event, and quickly asked Xiao Li, Xiao Li, Xiao Li, did not carry a reporter, and directly explained him directly.

The reporter listened to the suspication, "Peng Intermediate, did you just say that K03A does not improve the potential? Now K03A has improved, you think that R & D new alloy replaces K03A, how long does it take?"

Peng Enqi looked up and seeing the reporter, he didn't know how to open. He was rated as an academician of the Academy of Engineering, and also made many alloy material results, but the number of times the interview was limited, and the problem of 'diamond' for a time. I have a face red.

Waiting for a long time, Peng Enguo will open the mouth. "I don't know, the research and development is not allowed. I am here today."

"Xiao Li!"

Peng Enguo stood up, the tone immediately improved, "there is you", he pointed to other researchers and students, "return to the laboratory, our research and development will work overtime and continue!"

......

Aerospace University, Metal Composite Laboratory.

Wang Zhifang and Zhang Hongtao also saw the news. They were surprised by K03A. The 307 steel mill R & D group was released, 'In Zhao Wei's suggestion,', it is like Zhao Wei just to provide suggestions, research and development is really studying how to improve In fact, they are very clear that 'Zhao Wei's suggestion is very transparent', the 307 steel mill R & D group is only in accordance with the recommendations, and the performance of K03A can be said to be Zhao Wei's credit.

"and so……"

"Zhao Wei is really not talking, when he said there is a big problem, it is indeed a big problem!"

Wang Zhifang said with a satisfaction.

Zhang Hongtao is not so unexpected. He felt very normal. "Teacher Wang, I have already said, listening to Zhao Wei's definitely no mistake. He is a genius, we are ordinary people, we rely on experience, he relys with talent, But research, talents are more important. "

Wang Zhifang nodded.

Zhang Hongtao continued, "Before I have used Zhao Academician to develop research and development, his suggestion, really ... listening is right, the end result is the same as he said, there is a deck steel, Zhao's University of Zhao also gave it. I have a few suggestions. "

Wang Zhifang was surprised that there was no idea, asked, "What should we do now? Do K03A's research? But know how to start!"

"Wait."

"Wait?"

Zhang Hongtao said, "I have passed by Zhao's governments. He said that he is the news on the 307, in order to improve the K03A after enhancement, but I feel early."

"Is this early?"

Zhang Hongtao shook his head, "I still don't get it, according to I know, Zhao's suggestion report has just been submitted for a few days, 307 is definitely not perfected according to the proposal, for a while, look, definitely also improved."

Wang Zhifang's mouth dared to refute.

If you change it, he has been saying 'You are doing a dream. After seeing the news, he found that there is no way to say anything. Waiting for his suggestions being adopted, will K03A will improve?

However, the performance of K03A has improved, it has already been chasing the international level, it seems that it doesn't have to improve it again? If you want to continue to improve, is there any way to improve?

Wang Zhifang suddenly confused.

......

Yanhua University, Power Engineering Laboratory.

The work of the Kunlun engine style unit is very unreasonable, just maintaining a part.

Yuan Haitao, two engineers Zhou Qinghe Xue Fengge, sit in the office most, discuss Zhao Wei's improvement in the engine, now they are all clear, Zhao Wei is a big transformation of the prototype, from The transformation of the outside is over again.

For example, it is coming to the capital. They must not believe that a person's ability is limited, and the aviation launcher is too complicated, it can design a component, it is already very good, how can it be achieved from the inside?

Now they believe that Zhao Wei can do it, but how many effects are hard to say.

Zhao Wei's ability is quite worthy of affirmation, but limiting engine performance is not only designed, and there are some hard technologies, such as the material of turbine blades.

Previously, Zhao Wei has improved the combustion room, because there is a limit of turbine blades, the performance improvement of the combustion chamber does not make sense, even if there is an improvement, I don't dare to play all, otherwise it will lead to the turbine blade to bear the high temperature and fast. damage.

So the problem is the turbine blade.

"Difficult!"

Xue Fengdu sighed, "Zhao's academician is indeed very powerful, but the technical difficulties on the material ..."

He said all shook his head.

"Yeah, this is not possible. Just because of these restrictions, our group design, both of our groups, must have a result of alloy materials."

Yuan Haitao also said.

"There is a result!"

Zhou Qing suddenly exclaimed, "You look! There is a result, 307 said, the melting point of K03A has improved one hundred degrees!"

"real or fake?"

Yuan Haitao said very calmly, slowly walked over and looked at Zhou Qing's computer, and immediately widened, "it is really ..."

"What is it?" Xue Fengge has also left, and the three people went to the 307 steel mill R & D group, and suddenly was shocked.

For a long time.

Yuan Haitao sighed, "Zhao's academician, it's really! Well! It is also so fast that alloy materials are also developed!"

Zhou Qingdao, "He just said that it is necessary to study the materials of the turbine blades, I think that there is a result of the results, one year."

"Let's go!" Xue Fengng stood directly.

"What do you do?"

"Congratulations to Zhao Academician, anyway, we are also idle."

"It makes sense!"

"go!"

Three people got out of the door and walked to the far away, where the mechanical building gave the metal materials laboratory.

Zhao Yizheng looked at the list of applicants with Shen Zenghe, and other positions in the hard-speaking laboratory said, but the laboratory researchers must choose carefully and the ability is very important.

Shen Zezhehe believes that he should choose a foreignent, foreign turtle, a foreign turtle, the ability level is relatively good, and he still has a reason. "If English is better. If there is a result, you must publish the English papers."

"This doesn't matter."

Zhao Wei, "I have been going in English. If I don't know, we can find research and development, not to find translations, our domestic major colleges and universities can also."

Although English is really important, it is not necessarily important. It is not necessary to find a student, and it is enough for professional papers.

The two are talking.

Yuan Haitao found three people, and the entry is a big set of congratulations, Zhou Qing, Xue Fengfeng continues to say 307 news.

Zhao Yi listened to a few words and understood, "You said that 307 have a result? The melting point of K03A increased?"

"Increased one hundred days!" Yuan Haitao said very hard to show excitement.

Shen Zezhehe also followed, "This is too powerful! It will be added one hundred degrees directly, and it will definitely improve performance."

Zhao Wei frowned, "only one hundred degrees?"

Yuan Haitao, Zhou Qing and others pair, don't quite understand Zhao Wei, what is "only 'one hundred degrees?

Isn't a hundred degrees not enough?

Zhao Wei depressed, "I said, it should not be so fast, the value has increased one hundred degrees, it seems to solve the mixing, deoxidation problem, there is no solve."

He calmly, "Don't be excited, it is too early."

"307 has new results soon, I estimate that the melting point of K03A can also increase 50 degrees to 100 degrees, and the intensity will also increase."

Zhao Wei said that Yuan Haitao said three, and he reopened the Shen Zeharhea. "Let's continue!"
