Liu Wei walked in lightly and reported happily: "Boss, it's a good thing. Pratt & Whitney Company sent an official letter to buy our blade high-speed high-precision grinding technology, and the offer was 80 million US dollars."

Eighty million US dollars is really a lot, but Li Tianfeng knows that his technology is worth much more than 80 million US dollars. In addition, Li Tianfeng never considered transferring the technology, and the core technology must be in his own hands.

In the long run, if Tianfeng Technology Company can really become one of the world's advanced aero engine manufacturers in the future, Puhui may be a strong competitor, and such a key core technology cannot be sold to Puhui.

Li Tianfeng didn't even think about it: "Mr. Liu, replying to Pratt & Whitney, we have no intention of transferring this technology. If their aero engine blades are entrusted to us to use this technology to process it, I would be very welcome."

Upon hearing this, Liu Wei was stunned. Li Tianfeng was actually moved at all when facing the transfer fee of 80 million US dollars. However, Li Tianfeng was the boss. Liu Wei did whatever Li Tianfeng said. After being stunned, Liu Wei said: "Boss, then I will reply to Puhui according to your wishes."

Liu Wei nodded, and then reported a lot of work to Li Tianfeng, such as the construction work of the employee living community, administrative work, etc.

………

Assembly workshop.

Recently, Qiu Wen'an ran the assembly workshop the most diligent, because the first verification machine of the "tfwz001" type turboshaft engine has begun to fully enter the assembly work. Qiu Wen'an traveled to the assembly workshop almost every day to personally grasp the assembly situation.

In addition, as the director of the Process Technology Department, Zeng Qinghai also went to the assembly workshop every now and then, and the Process Technology Department checked the assembly process of the aircraft engine. Zeng Qinghai did not dare to take this first verification machine lightly.

It happened that both of them were in the assembly workshop, one was the design leader and the other was the craft leader. Of course, the biggest technical leader was Li Tianfeng.

When the two met in the assembly workshop, they naturally talked about the assembly of the verification machine. Zeng Qinghai said: "Mr. Qiu, the assembly of the first verification machine is really bumpy and exposed a series of problems."

Qiu Wen'an said: "Yes, there are many problems of various types. Fortunately, there are no major problems. We have recorded all the minor problems one by one. Some problems may have to be slightly changed in the design."

Zeng Qinghaidao: "We have also recorded a lot of assembly process issues, and we will immediately improve and improve it."

The two first talked about various design problems or assembly process problems exposed during the assembly process. Gradually, they talked about some things in the overall situation, such as the overall performance of this engine, the overall design or the overall process.

Zeng Qinghaidao: "Mr. Qiu, the processability of this engine is very good. Whether it is the processability of parts processing or the processability of assembly now, it is very good. Otherwise, it will definitely not be so easy."

Qiu Wen'andao: "Mr. Li has special requirements for the problem of craftsmanship. The design fully considers the craftsmanship, otherwise it would not be so smooth."

Both of them knew that if this engine had not had the excellent craftsmanship, the whole process would not have been so smooth. Otherwise, how could it have been assembled by the first verification machine so quickly?

Speaking of Li Tianfeng, both of them looked admirable. Although Qiu Wen'an is the chief designer of this engine, he basically completed the design work under Li Tianfeng's "step-by-step guidance".

Zeng Qinghai is basically the same. The process problems of some key parts are finally guided by Li Tianfeng. Otherwise, the processing of these parts will definitely not be so smooth. If it is done well, there will be constant problems during the processing process.

The two sat in the on-site rest area of ​​the assembly workshop and chatted for a long time. Then, the two went to see the assembly of each component together. Some minor problems arose during the assembly process. The two also patiently guided the assembly workers and played a guest-star technician.

"Mr. Qiu, according to our progress, in another ten days and half a month, our first verification machine will enter the real assembly stage."

Qiu Wendao: "It should be this speed. The first verification machine is an important milestone for us. If there is no major problem found when the test drive is verified, it would be great. The entire development and production process will be very fast in the future."

Zeng Qinghai said: "If we really design and shape it within three years, and develop our first prototype, we will create a miracle in the domestic aviation industry."

Qiu Wen'an agreed: "It is definitely an amazing miracle. The current situation in our country is that a new model of aircraft engine, from the beginning of design to the first prototype, there is no time for five, six years, or even seven or eight years, so don't even think about it."

At the same time, Qiu Wen'an secretly felt fortunate that if he had not resigned from the aircraft engine design institute before, he might still be unknown now, and how could he achieve such achievements today?

Zeng Qinghai was the same? If he had not joined Tianfeng Technology Company, he might still be a small technician now. He would not have the glory of today. His annual salary was one million yuan. He was the director of the Technology Department and was in charge of hundreds of process technicians.

The two looked at each other and nodded, feeling full of gratitude to Li Tianfeng, pride and joy for today's achievements.

………

In the office.

Li Tianfeng took the official reply letter from Puhui Company sent by Liu Wei and read it carefully.

Li Tianfeng refused the technology transfer of Pratt & Whitney. Today, Pratt & Whitney also made a formal reply, not considering entrusting a large number of blades of Pratt & Whitney's aircraft to Tianfeng Technology Company for processing, and only temporarily entrust one blade for processing.

At the back of the reply letter, a simple picture and a simple picture of the aircraft engine blades were attached. Li Tianfeng took a careful look. This is the fan blade of an old engine of Pratt & Whitney.

Titanium alloy material, solid fan blades, Li Tianfeng thought to himself, if you remember correctly, this is the fan blades of a turbofan engine that Pratt & Whitney began mass-producing in the early 1980s.

"I'm really cautious." Seeing this blade that came out thirty years ago, Li Tianfeng knew that the aviation industry has developed to this day, there is basically no need for technical confidentiality.

At the same time, Li Tianfeng also thought in his mind that although he signed a large order of nearly one billion US dollars with Pratt & Whitt Company last time, Pratt & Whitney Company entrusted itself to process them, basically some general parts of relatively old-fashioned aircraft engines, and even some parts of marine gas turbine engines.

As a world-wide large aviation industry enterprise, it is understandable to keep it confidential, but it is too cautious. This time, I just want to process the fan blades of an old-fashioned engine first.

"Try it first and then see, maybe you will have any surprises in the future." Li Tianfeng thought to himself.

Calling Liu Wei in, Li Tianfeng said: "Send a letter to Puhui, we both will sign a processing contract for this type of fan blade first."

After giving Liu Wei instructions, Li Tianfeng stood up and said, "Our first verification machine has entered the assembly. I will go to the assembly workshop. If you have any questions, call my phone."

"Mr. Li, do you want me to accompany you?" Liu Wei asked.

Li Tianfeng waved his hand and said, "Yes, bring the camera."

Although I don’t know why Li Tianfeng asked to bring a camera, Liu Wei still brought the camera and entered the assembly workshop with Li Tianfeng. After entering the workshop, Li Tianfeng only went to the assembly area.

In the assembly area, especially next to an engine assembly bench, Qiu Wen'an and Zeng Qinghai are already there, and Zhou Wensheng is also there in the assembly workshop.

Zhou Wensheng was in his thirties and used to be the director of the assembly workshop of a large domestic aviation industry enterprise. He had good abilities and rich experience. Hu Xiao poached it with a high salary.

"Hello boss!"

Everyone saw Li Tianfeng and Liu Wei coming over and greeted him one after another. Li Tianfeng nodded, "How is the situation?"

As the director of the assembly workshop, Zhou Wensheng immediately reported: "It is ready and the assembly of the first verification machine can be started soon."

Zhou Wensheng's tone was filled with a hint of uncontrollable joy and excitement. Upon hearing this, Li Tianfeng was basically the same. The first verification machine was about to be assembled.

Li Tianfeng waved his hand: "Start assembly now!!!"

The several workers responsible for the assembly are all skilled assembly workers and have rich experience in aircraft assembly. Obviously, the overall assembly process regulations of the "tfwz001" type turboshaft engine have been carefully digested. With Li Tianfeng's order, construction started immediately.

Several major components of the "tfwz001" type turboshaft engine have been assembled in advance. The assembly is to assemble these major components together and then assemble the accessories, including the control part, oil circuit, circuit, etc.

The assembly of an aircraft engine generally has an assembly plane reference and an assembly center shaft standard. The first thing to do is to determine these two references.

The installation side plane of the combustion chamber receiver and the turbine receiver of the "tfwz001" type turbine shaft engine is the assembly plane reference, and the main bearing installation hole in the center of the combustion chamber receiver is the central shaft installation reference.

The assembly workers have a very good technical level. They install the combustion chamber components on the assembly bench and carefully align these two references. After the two references are rectified, the intermediary receiver is installed, the centrifugal impeller is installed, and the flow conduit is installed...

Li Tianfeng was next to him and saw several assembly workers cooperating well and having good skills. Li Tianfeng nodded and thought to himself that this was the first aircraft assembly. Zhou Wensheng must have arranged the best technical workers, and those assembly workers with slightly lower levels did not arrange to participate.

Li Tianfeng said: "Mr. Liu, you are responsible for taking photos and taking pictures of every assembly detail."
