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

80 million US dollars is really a lot, but Li Tianfeng knows that the value of his own technology is far greater than 80 million US dollars, and in addition, Li Tianfeng has never considered transferring this technology, and the core technology must be in his own hands.

In the long run, if Tianfeng Technology can really squeeze into the world's advanced aero engine manufacturers in the future, Pratt & Whitney may be a powerful competitor of its own, and such key core technologies cannot be sold to Pratt & Whitney.

Li Tianfeng didn't think about it: "Mr. Liu, in terms of replying to Pratt & Whitney, we have no intention of transferring this technology, how can their aero engine blades be entrusted to us to use this technology for processing, I am very welcome." ”

Hearing this, Liu Wei was stunned, in the face of the transfer fee of 80 million US dollars, Li Tianfeng was actually not moved at all, but Li Tianfeng is the boss, what Li Tianfeng said, Liu Wei will do what he does, after being stunned, Liu Wei said: "Boss, then I will reply to Pratt & Whitney immediately according to your wishes." ”

Liu Wei nodded, and then reported a lot of work to Li Tianfeng, such as the construction of the staff living quarter, administrative work, and so on.

Final assembly workshop.

Recently, Qiu Wenan ran the assembly workshop is the most diligent, for no other reason, because the first verification machine of the "TFWZ001" turboshaft engine began to fully enter the assembly work, Qiu Wenan ran the assembly workshop almost every day to personally grasp the assembly situation.

In addition, as the head of the process technology department. Zeng Qinghai also ran to the assembly workshop every five or three times, and the process technology department checked the assembly process of the aero engine, and Zeng Qinghai did not dare to take it lightly for the first verification machine.

Coincidentally, both of them were in the final assembly workshop. One is the design faucet, the other is the process faucet, and of course, the biggest technical faucet is Li Tianfeng.

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

Qiu Wen'an said: "Yes, there are many problems of all kinds, but fortunately there are no major problems. We have recorded these small problems and small problems in detail one by one, and some problems may need to be slightly changed in design. ”

Zeng Qinghai said: "We have also recorded a lot of assembly process problems, and we will immediately improve and perfect." ”

The two first talked about some of the various design problems or assembly process problems exposed in the assembly process, and gradually, they talked about some things in the big picture. Such as the overall performance of the engine, the overall design or the overall workmanship.

Zeng Qinghai said: "Mr. Qiu, the craftsmanship of this engine is very good. Whether it is the process of parts processing, or the process of current assembly, it is very good, otherwise, it will definitely not be so smooth. ”

Qiu Wen'an said: "For technical problems, Mr. Li always has special requirements. In the design, the manufacturability is fully considered, otherwise. It won't be so smooth. ”

Both knew that if it weren't for the excellent workmanship of this engine. The whole process would not have been so smooth, otherwise it would have been possible to assemble the first verification machine so quickly.

Speaking of Li Tianfeng, both of them admired each other, although Qiu Wenan was the chief designer of this engine, he basically completed the design work under Li Tianfeng's "hand-in-hand guidance".

Zeng Qinghai is basically the same, the process problems of some key parts are also guided by Li Tianfeng in the end, otherwise, the processing of these parts will definitely not be so smooth, and if it is not good, there will be problems in the processing process.

The two sat in the on-site rest area of the assembly workshop and chatted for a long time, and then the two went to see the assembly of the parts together, and some small problems in the assembly process, the two also patiently guided the assembly workers and made a cameo appearance as a field technician.

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

Qiu Wendao: "It should be this speed, the first verification machine came out, it is an important milestone for us, if the test verification, no heavy dà problem is found, it is great, the follow-up of the entire development and production process will be very fast." ”

Zeng Qinghai said: "If it is really as Mr. Li said, the design is finalized within three years and our first prototype is developed, then we will create a miracle in the domestic aviation industry." ”

Qiu Wenan agreed: "It's definitely a great miracle, the current situation in our country, a new model of aero engine, from the beginning of the design to the first prototype, there is no five, six, or even seven or eight years, don't think about it." ”

At the same time, Qiu Wen secretly rejoiced in peace that if he had not resigned from the previous aero engine design institute, he might still be unknown now, where would there be such an achievement today.

Zeng Qinghai is not, if he hadn't joined Tianfeng Technology Company, he might still be a small technician now, where is today's scenery, with an annual salary of one million, the head of the process technology department, and hundreds of process technicians under his hands.

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

In the office.

Li Tianfeng took the official reply letter from Pratt & Whitney sent by Liu Wei and read it carefully.

Li Tianfeng rejected the technology transfer of Pratt & Whitney, and today, Pratt & Whitney also made a formal reply, temporarily not considering entrusting a large number of blades of various types of Pratt & Whitney to Tianfeng Technology Company for processing, and only temporarily entrusting a blade for processing.

At the back of the reply letter, a simple diagram of an aero engine blade was attached, and Li Tianfeng looked at it seriously, which was the fan blade of an old-fashioned engine of Pratt & Whitney.

Titanium alloy material, solid fan blades, Li Tianfeng thought to himself, if I remember correctly, this is the fan blade of a turbofan engine that Pratt & Whitney began mass production in the early eighties.

"It's really cautious." Seeing this kind of blade, which came out 30 years ago, Li Tianfeng knew that with the development of the aviation industry to this day, there is basically no need for technical secrecy.

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

As a large aerospace industry company in the world, secrecy is understandable, but it is also too cautious, and this time it is the same, only to process the fan blades of an old-fashioned engine first.

"Try it first, and then see, maybe there will be any surprises in the future." Li Tianfeng thought in his heart.

Calling Liu Wei in, Li Tianfeng said: "Send a letter to Pratt & Whitney, and we will first sign a contract for the processing of this kind of fan blade." ”

After instructing Liu Wei, Li Tianfeng got up and said: "Our first verification machine has entered the final assembly, I will go to the final assembly workshop, and if there is something to call my mobile 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 took the camera and entered the assembly workshop with Li Tianfeng.

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

Zhou Wensheng is in his thirties, and he used to be the director of the assembly workshop of a large domestic aviation industry enterprise.

"Hello boss!"

Everyone saw Li Tianfeng and Liu Wei coming over and said hello one after another. Li Tianfeng nodded, "How's the situation?" ”

Zhou Wensheng, as the director of the final assembly workshop, immediately reported: "It is ready, and the final assembly of the first verification machine can start immediately." ”

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

Li Tianfeng waved his hand: "Start assembling immediately!! ”

Several workers in charge of the general assembly are skilled assembly workers, have rich experience in aircraft assembly, obviously, the "TFWZ001" turboshaft engine assembly process has also been carefully digested, with Li Tianfeng's order, immediately started.

Several major components of the "TFWZ001" turboshaft engine have been assembled in the early stage, and the final assembly is to assemble these major parts together, and then assemble the accessories, including the control part, oil circuit, circuit and so on.

For the assembly of aero engines, there is generally an assembly plane datum and an assembly central shaft standard, and these two datums must be determined first.

The mounting edge plane of the combustion chamber casing and turbine casing of the TFWZ001 turboshaft engine is the assembly plane datum, and the main bearing mounting hole in the center of the combustion chamber casing is the central shaft mounting datum.

The technical level of the assembly workers is very good, the combustion chamber parts are installed on the assembly bench, carefully aligned the two benchmarks, and after the two benchmarks are aligned, the intermediary casing, centrifugal impeller is installed, and the shroud is installed......

Li Tianfeng was beside him, seeing that several assembly workers cooperated tacitly, and the level was good, Li Tianfeng nodded, and thought in his heart, this is the first aircraft assembly, Zhou Wensheng must have arranged the best skilled workers, and those assembly workers with a slightly lower level were not arranged to participate.

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