The 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 excitedly held a few turbine work blades and rushed in with a happy look on his face. While walking quickly to Li Tianfeng's desk, he said happily: "Boss, this is also our second batch of trial production. Look at the high quality of this processing, there is a significant difference from the previous batch, which is greatly improved."

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

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

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

Seeing this, Li Tianfeng couldn't help but feel excited. He took one of the leaves and looked at them carefully. He even took a magnifying glass and looked at them carefully.

Li Tianfeng said: "How is the measurement and inspection of the blade size?"

Zeng Qinghai said happily: "Boss, all the size measurements and inspections have passed. There are 27 blades in this batch, all the sizes are qualified, and more than half of them are excellent products."

Such processing quality, not to mention the trial production of new machines, is very good even if it is mass-produced. You can use it with confidence. Such processing technology can also be very safe.

Li Tianfeng said: "The quality of the blades is really good. The trial production of our turbofan 20 engine is very smooth and progresses very quickly. When the turbofan 20 engine is successfully developed, I will reward your process system with merits."

After hearing this, Zeng Qinghai was overjoyed. A few months ago, Tianfeng Technology Company issued an official red-headed document. Waiting for the successful development of the engine, it will select meritorious figures, outstanding figures, etc., with the highest reward of 500,000 yuan.

Five hundred thousand yuan!

Even Zeng Qinghai's annual salary has reached one or two million, but he is still jealous of this reward, such a heavy reward. Not only does he have a cash reward of 500,000 yuan, but it is also a huge honor.

The military's 106 Project develops domestic power for the main fighter aircraft in service. In such a project, it is enough to be pleased to have a brilliant mark.

Zeng Qinghai said happily: "Boss, our entire craft system is now fully committed. Everyone wants to be a meritorious figure."

Li Tianfeng gently patted Zeng Qinghai on the shoulder: "Mr. Zeng, do your best. I see your performance and remember it in my heart. In addition, as our Tianfeng Technology Company grows and grows, I am already considering further increasing the treatment level of our middle-level and senior managers."

Tianfeng Technology Company is moving towards a billion-level enterprise. In addition, it is a high-tech enterprise, and its products are all kinds of aircraft engines with extremely high technical content, requiring a large number of excellent and elite talents.

As the company grows and grows, the treatment of these outstanding and elite talents will gradually increase, allowing everyone to fully share the achievements of the company's development. Therefore, Li Tianfeng was considering in his mind that he would first improve the treatment of middle-level, senior managers, engineering and technical personnel at the supervisor level and above, design and R&D personnel.

Like Zeng Qinghai, he is not only the director of the Technology Department, but also the chief craftsman of Tianfeng Technology Company. His annual salary is about one million or hundreds of thousands, but he has not yet reached two million. To be honest, such treatment is a bit low.

Even if the people below did not mention it, Li Tianfeng remembered it in his heart and was always thinking about it.

Tianfeng Technology Company has a good financial situation. After all, it is a high-tech enterprise. The profit level of the aviation engine industry is far higher than that of ordinary machinery manufacturing. Each aviation engine of Tianfeng Technology Company is even more profitable.

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

Li Tianfeng had already thought about it in his mind, gradually improving everyone's treatment, increasing part of it every year, and taking three or five years to improve everyone's treatment to a relatively good level. Even if it cannot be compared with those well-known international aviation industry enterprises, it must at least be at the leading level in China.

When I heard that I wanted to improve the treatment level of middle- and senior managers like myself, 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."

"Yes." Li Tianfeng nodded slightly, and then said: "Mr. Zeng, go and 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 Zeng Qinghai's back as he left and looking at the leaves on his desk, Li Tianfeng thought to himself, perhaps, the comprehensive trial production of each part and a series of related tests and verifications can be completed before the end of the year.

Originally, the military's goal is to complete the comprehensive design of the turbofan 20 engine this year and complete the comprehensive trial production of the turbofan 20 engine parts next year. The design of the turbofan 20 engine of Tianfeng Technology Company is almost half a year ahead of the military's requirements. If the comprehensive trial production of the parts can be 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 be waiting for the turbofan 20 engine. It is not a long-term solution to import the engine from Mao Laozi for a long time. Domestic engines are the reliable and feasible ways.

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 complete turbofan 20 engine by the end of this year.

Originally, when Li Tianfeng first designed the turbofan 20 engine, he wanted to make major design improvements to the combustion chamber and turbine parts based on the core engine of the turbofan 16 engine.

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

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

In Li Tianfeng's memory, there are very advanced combustion chamber designs and very advanced turbine designs. Combined with Tianfeng Technology's current technical strength level, as well as the existing material level and process level, Li Tianfeng can completely design more advanced combustion chambers and more advanced turbines.

The turbofan 20 engine has not yet adopted these advanced designs. However, considering that technical preparations can be made for the next engine, Li Tianfeng designed the third generation high-thermal load combustion chamber and used on the rq2000 gas turbine shaft engine to verify on this engine.

The design of the advanced turbine part is crucial to an advanced aircraft engine. In Li Tianfeng's memory, there is a high-efficiency turbine design. Such a turbine design not only has a high gas utilization rate, but also can provide greater thrust for the engine under the same gas level, but also has a greatly extended service life of such a turbine.

Li Tianfeng believes that the current material and process conditions of such turbine design are ripe, but there is currently no suitable engine for this design to be verified.

Li Tianfeng thought to himself, maybe Tianfeng Technology Company is going to develop the core engine design of the next generation of advanced aircraft engines. Core engines are the first, which is a common practice.

Turbine Fan 16, Turbine Fan 17, Turbine Fan 18, and the Turbine Fan 20 engines 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 lacks core engines. For the long-term consideration of the future, it can indeed develop the core engine of this generation of aviation engines, and at least develop the leading design.

Based on this consideration, Li Tianfeng said in his heart that this matter should be put on the agenda. If the guess is correct, when the turbofan 20 engine is successfully developed, the military should issue the development of the next small-channel-based military turbofan engine.

The next military turbofan is definitely more advanced than the turbofan 20 engine and has better overall performance requirements. The current core engine level will definitely not meet the design of this engine.

In addition, those aircraft engine giants have established joint companies and will definitely jointly launch an advanced regional passenger aircraft power in the near future.

If Tianfeng Technology does not have an advanced core phone in its hands, it will be really troublesome and difficult.

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. However, if there is an advanced core machine, the situation will be different.

For example, the current turbofan 20 engine has a ready-made core engine, so the engine design can be completed within half a year and the comprehensive trial production of various parts can be completed before the end of this year. Otherwise, there would be no need to think about it, and there would definitely be no such process.

With such considerations in mind, Li Tianfeng was paying attention to the trial production of the parts of the turbofan 20 engine, and thought about the design of the next generation of core machines. The design of this generation of core machines gradually took shape in Li Tianfeng's mind.

When the time entered November, a big thing happened in the international aviation industry, and the impact on Tianfeng Technology Company was the first to be affected!
