Li Tianfeng saw the subtle changes in the mental outlook of the company's employees and was happy in his heart.√∟,

Today, Li Tianfeng just came back from the second phase construction site and looked around there. Li Tianfeng was quite satisfied. He is worthy of being the design of a famous domestic architectural design team. It is very scientific and reasonable, and beautiful and generous. At present, the construction of a good factory building is coming to an end.

Back to the office.

Li Tianfeng took a sip of tea comfortably, then picked up a craft rule on his desk, looking serious.

This is the newly compiled casting process regulations for single crystal turbine blades. The process method used is exactly the directional solidification casting process technology mentioned last time. Li Tianfeng took it seriously.

I have to say that Zeng Qinghai has a relatively thorough understanding of this new process and has basically understood his own meaning. However, there are still some details and process parameters that are lacking.

Li Tianfeng was not polite either. He picked up a pen and looked at it while correcting it. Li Tianfeng waved his pen to correct the inappropriate and wrong places.

After such a change, this craft regulation has a bit of unrecognizable flavor. Many places have even been greatly modified, full of things, words, numbers, and even arrows, crossbars, etc.

After changing it for at least an hour, Li Tianfeng was very satisfied with it, he picked up the phone and called Zeng Qinghai in again.

Zeng Qinghai came quickly. In just a few minutes, Zeng Qinghai knocked in and said, "Boss, please come to me."

Li Tianfeng nodded and said, "Qinghai, I have corrected the process regulations. I will talk to you about some key issues and parameters."

After taking the process rules for printing this blank paper, Zeng Qinghai looked through it a little, and seeing that there had been many changes, he couldn't help but blush. He felt a little embarrassed.

Zeng Qinghai said: "Boss, I am so ashamed. I still haven't fully understood the essence of directional solidification casting technology."

Li Tianfeng said: "It doesn't matter. After you change the process regulations, you can organize relevant personnel to digest them according to my requirements. I believe it will be another big step forward. Come on, let me tell you first where you have not fully understood it."

Li Tianfeng took out the paper and pen and explained in detail. After this lecture, Zeng Qinghai finally had a basic understanding and said gratefully: "Boss, now I know it completely. It turns out that there are so many key areas. I will go back and improve this craftsmanship regulations."

Li Tianfeng said: "Well. Hurry up, our single crystal turbine blades will also begin trial production, and I hope they can be manufactured smoothly."

Zeng Qinghai also clicked a little and thought to himself that it would be great if he could really cast high-quality single crystal blades according to directional solidification technology.

………

When time moved to mid-September, the comprehensive development of the turbofan engine of Tianfeng Technology Company was basically coming to an end and began to enter the stage of comprehensive trial production.

This progress is very fast. On the one hand, it is mainly because of Li Tianfeng, a highly skilled helmman. On the other hand, it is because Tianfeng Technology Company has experience in successfully designing turboshaft d and turboshaft e engines.

In the office.

Li Tianfeng was looking at a turbine blade with great enthusiasm. This is not a simple turbine blade. This is the third generation single crystal turbine blade. It adopts the latest and most advanced directional solidification casting technology, and the blades look very beautiful.

Not only is it hollow, but the curved surface of the blade is also very beautiful. The leaves are lined up by rows of tiny cooling pores, and the blades are also very beautiful. The design of the blade is an ultra-cold design, and the blades are sprayed with a thermal barrier coating.

Because of the coating, the leaves are gray-black. It has a special beauty. Li Tianfeng was watching the leaves and Liu Wei knocked on the door and came in.

Seeing the blade in Li Tianfeng's hand, Liu Wei asked: "Boss, this is the turbine blade of our turbofan engine!"

Li Tianfeng nodded: "Well, the third-generation single crystal blade represents the highest level in China. Looking at the international level, such blades are also top-notch."

Liu Wei said: "Boss, it is very difficult to test the blades like this."

Li Tianfeng said: "We use directional solidification casting technology, which is quite smooth. After several batches of trial production, the process has basically matured. In the future, if we carry out the manufacturing of this kind of blade, it will be smoother."

The key to manufacturing blades like this is to have mature process technology. As long as the process is mature, it will be done according to this process in the future. Generally, there will be no problems.

Liu Wei said happily: "Boss, then I want to congratulate you."

Li Tianfeng smiled, put down the leaf, and then said to Liu Wei: "Mr. Liu, what's the matter with me?"

Liu Wei said happily: "Boss, good news, the Shang-fei Company sent a letter to one of their vice presidents to inspect our company tomorrow."

Shang-fei Company, Li Tianfeng naturally knew that the company's Xiang-Feng regional passenger plane was more famous, and he also knew that the current Xiang-Feng regional passenger plane was temporarily tried with a turbofan engine from Ge Company.

Upon hearing this, Li Tianfeng seemed to see the business opportunity and was overjoyed. Originally, as his turbofan engine began to enter the trial production stage of comprehensive parts, Li Tian began to consider how to promote his turbofan engine.

Because the design has not been finalized, this advanced turbofan engine is very low-key and has basically not unveiled the mystery in front of the world. There are few people who know this engine, and even in the domestic aviation industry, few people know about it.

It is known that Tianfeng Technology is developing a turbofan engine, but it is definitely not bad for the development progress, engine performance, etc.

Perhaps, it is because the turbofan engine is very technical, and the development of advanced turbofan engines is even more difficult, requiring strong design technology and process technical support. No one is optimistic about Tianfeng Technology Company, and no one is interested in learning more about it.

Otherwise, if you come to the aviation industry to know this turbofan engine in detail, you can still sit still. Such a turbofan engine will not turn the domestic aviation industry upside down.

Li Tianfeng was overjoyed and said, "Mr. Liu, this is a good thing. We welcome their arrival."

Liu Wei smiled sweetly.

………

On a passenger plane.

Shen Wensheng took his assistant and rode on the plane very low-key. Shen Wensheng's destination this time was Tianfeng Technology Company in Songzhou City.

Shen Wensheng also learned from his assistant Xiao Zhao a few days ago that Tianfeng Technology Company was developing a power for civilian branch technology and a medium-sized turbofan engine. After hesitating for two days, Shen Wensheng held a glimmer of hope and prepared to go to Tianfeng Technology Company to take a look.

Why just hold a glimmer of hope? Because as an insider in the industry, Shen Wensheng is well aware of the domestic aviation industry level and believes that it is basically impossible to have any advanced turbofan engines. Even if there is one, it will be given priority to military use. Perhaps, Tianfeng Technology Company is the same. This turbofan engine under development may disappoint himself.

If Shen Wensheng had not learned that Tianfeng Technology had successfully developed turboshaft D and turboshaft e engines with outstanding performance, Shen Wensheng would not have even come to Tianfeng Technology.

This time, because he was just looking for a little hope, Shen Wensheng was very low-key and only brought one of his assistants without making any big fuss.

Shen Wensheng said: "Xiao Zhao, can the turbofan engine that Tianfeng Technology is developing meet our requirements?"

Shen Wensheng asked such a question no less than five times, and his assistant Xiao Zhao said: "Mr. Chen, I also heard from my classmates that my classmate works in Tianfeng Technology Company and told me about such a turbofan engine. But when I asked again, my classmate didn't mention it, saying that it was a confidentiality rule and he could not violate it."

Shen Wensheng said: "I hope we won't be disappointed this time. From next year, Ge will reduce our engine share. It's September now, so there's not much time left for us."

Xiao Zhao nodded solemnly, and then said a little worriedly: "Mr. Chen, our regional passenger plane uses the GE company's 34-10a turbofan engine. I don't know what the performance of the turbofan engine developed by Tianfeng Technology Company is, and whether it can be better than the 34-10a."

Shen Wensheng really dared not have too much hope for this. In Shen Wensheng's view, the 34-10a is a good engine, otherwise, this turbofan engine would not have been used as Xiang Feng's power.

In his mind, Shen Wensheng showed detailed data of 34-10a.

34-10a is one of the best-selling 34 series engines in GE. To date, the 34 has a total of 6,600 fixed and intended orders worldwide, single-stage fans, 3-stage supercharged stage, 9-stage compressor 4-stage low-pressure turbine, 1-stage high-pressure turbine...

After thinking for a long time, Shen Wensheng sighed and thought to himself, maybe he had a waste of time this time and was about to return in disappointment.

Xiao Zhao, the assistant next to him, couldn't help but sigh in his heart when he saw Shen Wensheng's expression, and thought to himself that this time might be useless. This turbofan engine from Tianfeng Technology Company may be really not very good.

Seeing that Shen Wensheng closed his eyes and leaned against the seat, Xiao Zhao had no intention of talking again, and his heart was filled with worry.
