Tianfeng Technology Company.

Li Tianfeng promised Lin Ziming, naturally he would not break his promise, and on the same day, the rough drawings of the turbine disc of AVIC Group were sent to Tianfeng Technology Company.

Li Tianfeng personally looked at the blank diagram and knew that the material grade of this turbine disc was FGH95, which had been localized, but there was a big difference in quality and imported materials, mainly because there was a gap in the process level.

Such powder metallurgy materials, Tianfeng Technology Company is naturally a piece of cake, not to say that it is FGH95, that is, a higher level, more advanced FGH99 Tianfeng Technology's technology is very mature.

The so-called powder metallurgy is a process technology that manufactures metal materials, composite materials and various types of products by preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering.

Powder metallurgy has similarities with the production of ceramics, both belong to powder sintering technology, therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials and plays a pivotal role in the development of new materials.

After reading the blank drawing, there was no technical difficulty, Li Tianfeng directly gave the drawing to Zeng Qinghai, and the process technology department was responsible for the process technology of this batch of turbine disc blanks.

At present, Li Tianfeng is most concerned about the development of the turbofan 20 engine and the improvement and modification of the turbofan 16 engine.

The two turbofan 16 engines used for the test flight of the Airbus A320 passenger aircraft are personally responsible for the improvement and modification of the aircraft by Sun Xiaoping, and the technical communication and coordination with Airbus are also responsible for Sun Xiaoping, the improved and modified turbofan 16 engine, its model is WS16B.

Li Tianfeng is not ready to personally intervene in a series of matters of the WS16B engine, design technology. Sun Xiaoping is specifically responsible, and Li Tianfeng is very relieved.

The basic performance of the WS16B engine remains the same, only the fan size has been slightly modified in order to work well with the Airbus A320 airliner, and this technical work. Sun Xiaoping is fully competent.

In the office.

Li Tianfeng said: "Mr. Sun, you are specifically responsible for the improvement and modification design of the WS16B engine, there is no problem!" ”

Sun Xiaoping said confidently: "Boss, there is no problem, I will definitely complete the improvement and modification of this engine as soon as possible,"

Li Tianfeng said: "Mr. Sun, we only have 6 months, you complete the modification and design of the relevant drawings, I only give you one month." ”

Only give a month. On the one hand, it is to consider that the workload is not large, but only part of the design drawings are modified on the basis of the original, on the other hand, it is mainly to consider that after the drawings are modified and the design is completed, the relevant parts will be processed and manufactured, tested, and the test run of the engine and a series of work such as the new design drawing.

Surprisingly. Sun Xiaoping said confidently: "Boss, one month is enough." Within a month, we will complete the formal revision of the relevant drawings, leaving enough time for our next part trial production. ”

"Hmm." Li Tianfeng nodded.

………

Today, Li Tianfeng took a turn in the process technology department and looked at the compilation of the processing process specification for turbofan 20 engine parts, some key and difficult parts. Li Tianfeng also personally took a special look at the compiled process regulations.

After looking at the process specifications of each part, Li Tianfeng felt more relieved, and praised Zeng Qinghai and others.

After so many years, whether it is Zeng Qinghai. Or the following series of process technicians, everyone has gradually grown up.

Zeng Qinghai was naturally very happy to be praised, and also thanked Li Tianfeng, Zeng Qinghai said happily: "Boss, thank you for greatly enhancing the strength of our process technology department, otherwise, the preparation of these process regulations has not been so smooth." ”

In this year's spring talent recruitment fair in Songzhou City, Tianfeng Technology Company has become the most dazzling star enterprise in the entire job fair, not only recruiting more than 2,000 employees of all kinds, including many technical personnel, and a large number of front-line technical workers.

Among these people, many of them are highly educated talents, including many postdoctoral and doctoral, among this group of technicians, there are two or three hundred process technicians, basically mature talents.

Among these process technicians, dozens of them have been enriched to the process technology department, and the rest are temporarily assigned to subordinate workshops.

This time, recruiting so many people, mainly for the Qingshi base to do talent reserves, the current Qingshi manufacturing base, ten large factories have been fully capped, part of the plant into the installation and commissioning of equipment, it is estimated that another month, some personnel will begin to work in the Qingshi manufacturing base.

Li Tianfeng smiled, and then said: "Among the process technicians recruited this time, there are more than 20 senior engineers with rich work experience. ”

Zeng Qinghai said: "Boss, don't worry, I will definitely use these people well." ”

Li Tianfeng nodded, and then said: "Mr. Zeng, our turbofan 20 engine is about to complete the comprehensive design, and began to enter the preparation of the processing process regulations of each part, and I am very relieved that the process regulations of other parts are compiled. ”

Zeng Qinghai hurriedly said: "Boss, there is no problem, I will personally check it, in addition, the process regulations of some parts with a relatively large amount of changes in the fan part will be sent to you after the preparation is completed." ”

Turbofan 20 engine, most of the parts and turbofan 16 engine are highly similar, the preparation of the process specification also has a ready-made process can be referenced, the difficulty of preparation is greatly reduced, Li Tianfeng is naturally relieved, basically rarely personally look at the relevant process regulations.

Only the fan part with a relatively large amount of changes, and the key parts of this part, such as the fan casing, fan blades, fan trays and other parts, Li Tianfeng is ready to check it personally.

In the process technology department, Li Tianfeng and Zeng Qinghai chatted for a long time.

In the afternoon, Li Tianfeng was concerned about the turbofan 20 engine, and Li Tianfeng went to the aero engine research and development center to see the design and development of the turbofan 20 engine.

Turbofan 20 engine, turbine part has taken the lead in completing the formal design, combustion chamber part, compressor part, accessory part, control system part and so on are basically completed design, the design amount of the fan part is slightly larger, its design workload has been completed for the most part, many important parts have been completed design.

An important and complex part such as the fan casing has been fully designed and passed the first design review.

On Sun Xiaoping's computer, Li Tianfeng personally looked at the design drawing of the fan casing, and it was still a 3D design drawing, and the entire fan casing was very beautiful.

Li Tianfeng said: "Mr. Sun, the fan casing can't be designed." ”

Sun Xiaoping said: "Boss, the main thing is that you have the original design sketch, otherwise, the design would not have gone so smoothly and progressed so quickly." ”

Li Tianfeng looked at the 3D design of the fan casing with great interest, the fan casing of the turbofan 20 engine and the fan casing of the turbofan 16 engine are relatively similar, but there are great differences.

The fan casing of the turbofan 20 engine is much smaller, the fan casing of the turbofan 16 engine is very large, with a diameter of more than one meter six, and the fan casing of the turbofan 20 engine is much smaller, with a diameter of only seven or eight hundred millimeters.

In addition, the fan casing of the turbofan 20 engine is longer than that of the turbofan 16, like a long cylindrical cylinder, and outside this long cylindrical cylinder, a large number of pipes, wiring, a large number of accessories, etc. will be installed.

In the whole engine, the fan casing is definitely one of the very complex and very critical parts, such parts, the design has been completed, Li Tianfeng is very satisfied.

After taking a serious look, Li Tianfeng said: "There is basically no problem with the fan casing, I think it can be officially finalized and the official design drawing can be issued." ”

Sun Xiaoping was overjoyed, "Boss, we have completed the design of several important and key parts of the fan part, such as the fan casing, fan blades, fan trays, etc., I estimate that at most one month, we will fully complete the design of the fan part, and at most two months, we will be sure to complete the comprehensive design of the turbofan 20 engine." ”

Li Tianfeng said: "The progress is good, when the comprehensive design is completed, I want to reward you well." ”

Sun Xiaoping was overjoyed, and suddenly, he was full of energy.

…………

The design of the turbofan 20 engine is progressing smoothly, and Li Tianfeng naturally wants to communicate with Zhang Haiping, no, Li Tianfeng took the initiative to call over.

Li Tianfeng said: "Minister Zhang, there is something I need to report to you. ”

Zhang Haiping laughed, "Mr. Li, what are we doing so politely between our old friends, what do you report or not, let's talk about it, what's the matter." ”

Li Tianfeng said: "Minister Zhang, the design of our turbofan 20 engine is progressing very smoothly, and it is estimated that we will complete the design in two months at most." ”

"What! Complete the full design! So fast! Zhang Haiping was stunned for a while, and then, with great joy in his heart, said happily: "Mr. Li, how correct our decision was to choose you to develop this engine, and to complete the comprehensive design so quickly, several months faster than we expected." ”

Originally, according to the military's plan, the design of the turbofan 20 engine was fully completed by the end of this year, but I didn't expect that Tianfeng Technology would give such a big surprise, but it was several months ahead of schedule!
