These first-stage compressor blades on Li Tianfeng's desk were also sent by Zeng Qinghai, and Li Tianfeng asked Zeng Qinghai to send them.

Now, Zeng Qinghai rushed in with a happy face while holding a few turbine working blades in a hurry, and said happily while walking quickly to Li Tianfeng's desk: "Boss, this is also our second batch of trial production, you see that the processing is of high quality, and there is a clear difference from the previous batch, and it has improved a lot." ”

The blade in Zeng Qinghai's hand is the high-pressure turbine working blade of the turbofan 20 engine, the third-generation single crystal blade, the super cooling structure design, and the directional solidification molding casting process.

Such blades are very similar to the high-pressure turbine blades of the turbofan 16 engine, the amount of change is very small, and when the first batch of blades is trial-produced, there are more or less quality problems and process problems, and when the second batch of blades are trial-produced, it is obviously different.

High-pressure turbine blades, which are important and key parts of the engine, can achieve such excellent quality in only two batches of trial production, no wonder Zeng Qinghai is so happy.

Seeing this, Li Tianfeng couldn't help but be interested, took one of the leaves, looked at it carefully, and even took a magnifying glass and looked at it seriously.

Li Tianfeng said: "How about the size measurement and inspection of the blades? ”

Zeng Qinghai said happily: "Boss, the size measurement and inspection are all qualified, this batch has a total of 27 blades, and the size is all qualified, and more than half of them are excellent products." ”

Such processing quality, not to mention the trial production of a new machine, even if it is mass production, it is also very good, and it can be used with confidence, such a processing process. You can also rest assured.

Li Tianfeng said: "The quality of the blades is really good, our turbofan 20 engine, the trial production of various parts is very smooth, and the progress is also very fast. ”

Hear the words. Zeng Qinghai was overjoyed, a few months ago, Tianfeng Technology Company issued a formal red-headed document, to be successfully developed by the engine, will be selected meritorious figures, outstanding figures, etc., with a maximum reward of 500,000 yuan.

500,000 yuan!

Even Zeng Qinghai, whose annual salary has reached one or two million, is also jealous of this reward, such a heavy reward. Not only is there a cash prize of 500,000 yuan, but it is also a huge honor.

The military's 106 project, which develops domestic power for the main fighters in active service, can leave a strong mark in such a project, which is enough to be gratifying in life.

Zeng Qinghai said with a happy face: "Boss, our entire process system is now fully developed. Everyone wants to be a meritorious person. ”

Li Tianfeng gently patted Zeng Qinghai's shoulder: "Mr. Zeng, do a good job." In addition, with the development and growth of our Tianfeng Technology Company, I am already considering further increasing the treatment level of our middle and senior managers. ”

Tianfeng Technology Co., Ltd. is moving towards a 100-billion-level enterprise. In addition, it is a high-tech enterprise, and its products are all kinds of aero engines with high technical content, which requires a large number of excellent and elite talents.

As the enterprise develops and grows, the treatment of these outstanding and elite talents will gradually improve, so that everyone can fully share the fruits of enterprise development. Therefore, Li Tianfeng is considering in his heart, first of all, to improve the treatment of middle and senior managers, engineering and technical personnel above the supervisor level, and design and development personnel.

Like Zeng Qinghai, not only the Minister of Process Technology, but also the chief technologist of Tianfeng Technology Company, with an annual salary of about 1 million yuan, it has not yet reached 2 million.

Even if the people below didn't mention it, Li Tianfeng kept it in mind and kept thinking about it.

Tianfeng Technology Co., Ltd. is in good financial condition, after all, it is a high-tech enterprise, and the profit level of the aero engine industry is much higher than that of general machinery manufacturing, and every aero engine of Tianfeng Technology Co., Ltd. is even more profitable.

With money in hand, Li Tianfeng has made a decision in his heart to comprehensively improve everyone's treatment, so as to further improve everyone's work enthusiasm and enthusiasm, and also make Tianfeng Technology Company full of attraction to those outstanding talents and elite talents.

Li Tianfeng has already thought in his heart that he will gradually improve everyone's treatment, increase a part of it every year, and use three or five years to raise everyone's treatment to a relatively good level, even if it cannot be compared with those well-known aviation industry enterprises in the world, but at least it must be at the leading level in China.

Hearing that the treatment level of middle and senior managers like himself should be improved, Zeng Qinghai said happily: "Boss, thank you, I think if you know this news, you will definitely work harder and make your greatest contribution to the company." ”

"Hmm." Li Tianfeng nodded slightly, and then said: "Mr. Zeng, go ahead, complete the comprehensive trial production of our turbofan 20 engine as soon as possible." ”

"Yes!" Zeng Qinghai stood up, and then strode out of Li Tianfeng's office.

Looking at the back of Zeng Qinghai leaving, and looking at the blades on his desk, Li Tianfeng thought in his heart, perhaps, before the end of the year, a comprehensive trial production of each part and a series of related tests and verifications can be completed.

Originally, the military's goal was to complete the full design of the turbofan-20 engine this year and the full-scale trial production of turbofan-20 engine parts next year. The turbofan 20 engine design of Tianfeng Technology Company is almost half a year ahead of the military's requirements, and if the full trial production of parts can be fully completed before the end of this year, the overall development process of the turbofan 20 engine will be at least one year faster than the military's expectations.

The military must also be waiting for the turbofan 20 engine, and the engine has been imported from Mao Laozi for a long time, which is not a long-term strategy, and the domestic engine is a reliable and feasible way.

Li Tianfeng thought about it for a long time in his office, and after thinking for a long time, he was full of confidence in the comprehensive design of the fully turbofan 20 engine by the end of this year.

Originally, at the beginning of the design of the turbofan 20 engine, Li Tianfeng wanted to make significant design improvements to the combustion chamber and turbine part on the basis of the core engine of the turbofan 16 engine.

However, seeing that the military was only preparing to use the turbofan 20 engine as the power of the J-10 and J-11, Li Tianfeng knew that there was no need for the turbofan 20 engine to be designed so advanced, so the combustion chamber part and the turbo part were almost copied from the turbofan 16, and the amount of change was very small.

This also greatly shortens the development cycle, after all, this is a ready-made thing, otherwise, there is no such rapid development progress.

In Li Tianfeng's memory, there is a very advanced combustion chamber design, there is also a very advanced turbine design, combined with the current technical strength of Tianfeng Technology Company, as well as the existing material level and process level, Li Tianfeng can design a more advanced combustion chamber, a more advanced turbine.

The turbofan 20 engine does not adopt these advanced designs for the time being, but considering that the technical preparation for the next engine can be made, Li Tianfeng designed the third-generation high heat load combustion chamber, and used it on the RQ2000 gas turboshaft engine for verification on this engine.

The design of the advanced turbine part is very important for an advanced aero engine, Li Tianfeng remembers, there is a high-efficiency turbine design, such a turbine design, not only the gas utilization rate is very high, under the same gas level conditions, can provide greater thrust for the engine, and the service life of such a turbine is greatly extended.

Li Tianfeng believes that the current material conditions and process conditions of such a turbine design have matured, but there is no suitable engine for this design to be verified for the time being.

Li Tianfeng thought in his heart, perhaps, Tianfeng Technology Company wants to develop the core engine design of the next generation of advanced aero engines. It is a common practice that the core machine comes first.

Turbofan 16, turbofan 17, turbofan 18, and the turbofan 20 engine currently under development are all fourth-generation turbofan engines, with a thrust-to-weight ratio of 10.

In order to develop a turbofan engine with a thrust-to-weight ratio of 15 or above, Tianfeng Technology Company temporarily lacks a core machine, and for the long-term consideration of the future, it is indeed possible to carry out the development of the core engine of this generation of aero engine, at least to carry out the first design.

Based on such considerations, Li Tianfeng said in his heart, this matter should be put on the agenda, if the guess is correct, when the turbofan 20 engine is successfully developed, the military should order the development of the next small signal than the military turbofan engine.

The next military turbofan is definitely more advanced than the turbofan 20 engine, and the comprehensive performance requirements are more excellent.

In addition, those aero engine giants have established a joint company, and in the near future, they will definitely jointly launch an advanced regional airliner power.

If Tianfeng Technology Company does not have an advanced core machine in its hands, it is really troublesome and tricky.

There is no advanced core machine, if you want to launch a more advanced and excellent engine, the development cycle and development difficulty will be greatly increased, but if there is an advanced core machine, then the situation is different.

Like the current turbofan 20 engine, there is a ready-made core machine, so the comprehensive design of the engine can be completed within half a year, and the comprehensive trial production of each part can be completed before the end of this year, otherwise, there is no need to think about it, there is definitely no such process.

With such a consideration in mind, Li Tianfeng paid attention to the trial production of parts of the turbofan 20 engine, and at the same time considered the design of the next generation of core machines, and the design of this generation of core machines gradually took shape in Li Tianfeng's mind.

When the time entered November, a big event happened in the international aviation industry, and the impact on Tianfeng Technology Company was the first to bear the brunt!
