Qingshi production and manufacturing base is gradually on the right track, Tianfeng Technology Co., Ltd. headquarters, also completely liberated, fully engaged in the production of turbofan engines, in the past, because of the production of turboshaft D and turboshaft E engines, the monthly output of turbofan engines is generally more than 100 units.

Now, because there is no longer a need to produce turboshaft D and turboshaft E engines, which are produced by the Qingshi manufacturing base, the monthly production capacity of Tianfeng Technology's turbofan engines is close to 200 units.

In Li Tianfeng's heart, the goal is clear, and his ultimate goal is to build Tianfeng Technology Company into a hegemon in the aviation industry and stand at the top of the aviation industry.

In order to achieve this goal, Li Tianfeng will work hard step by step, at present, the Qingshi manufacturing base has entered normal production, and then the production capacity of turbofan 16, turbofan 17 and turbofan 18 engines has also been greatly commissioned, and there is no longer any need to worry about production capacity.

With a monthly output of 200 turbofan engines, the annual output will exceed 2,000 units, which is a very gratifying production capacity data.

In the mass production of engines, there is no pressure, Li Tianfeng focuses on the development of engines, and if he wants to eventually become the hegemon of the aviation industry, he must do a good job in the development of each engine from now on.

Blade machining center.

On the inspection bench, dozens of fan blades are being inspected, these fan blades, at first glance, thought to be the fan blades of the turbofan 16A engine (the previous turbofan 16 engines are all called turbofan 16A, in order to distinguish from the current turbofan 16B engine), but if you look closely, there is a little difference, this is the fan blades of the turbofan 16B engine.

Because the fan blades are highly similar to those of the turbofan 16A engine, the process methods and process parameters are also basically similar. The trial production was relatively smooth, no, the trial production of the first batch of fan blades has been completed.

From the start of trial production to the completion of the first batch of trial production, it took less than a month, which can be regarded as a very fast progress.

This batch of fan blades. There are fifty pieces in total, neatly placed on the inspection table, and an inspector, wearing snow-white gauze gloves, is seriously inspecting.

The first is the appearance inspection, one by one the blades carefully looked, there are no appearance defects, after entering the appearance inspection. The inspector began to inspect the dimensions of the blades one by one in accordance with the requirements of the inspection process.

This inspector was so engrossed and very serious that Li Tianfeng and Sun Xiaoping walked to the side of the inspection table before they found out.

Putting down the blade in his hand, the inspector hurriedly said: "Mr. Li, Mr. Sun, hello." ”

Li Tianfeng is very easy-going. He waved his hand and said, "Master Tang, it's okay." You're busy, let's take a look at the fan blades. ”

Li Tianfeng often comes to the processing site, and many front-line workers Li Tianfeng have an impression and know that the inspector's surname is Tang.

Master Tang also knew that Li Tianfeng was more accommodating to the workers below, and seeing this, he also began to inspect this batch of fan blades again.

Li Tianfeng put on white gloves. picked up a leaf, looked at it with great interest, and while looking at it, he said to Sun Xiaoping next to him: "Mr. Sun, look." The quality of the blades is good, and the blades are very beautiful. ”

Sun Xiaoping also said: "Our fan blades, the surface of the blade is first superplastic pressed molding, and then after high-precision high-speed grinding, the blade accuracy is very high, and it is also very beautiful. ”

This is the fan blade produced by Tianfeng Technology Company, which is better than other aero engine companies, such a wide-chord air titanium alloy fan blade, everyone uses superplastic molding and diffusion connection process, but Li Tianfeng on this basis, the blade performance surface has been high-precision and high-speed grinding, the blade has higher precision and better quality.

Li Tianfeng nodded, for the wide-chord titanium alloy hollow fan blades, the processing technology of Tianfeng Technology Company is undoubtedly very advanced, and the quality of the blades is also very outstanding, which Li Tianfeng fully agrees with.

After reading the blade in his hand, Li Tianfeng personally picked up the measuring tool, and he didn't need to look at the inspection process regulations, the main and key dimensions of the blade, Li Tianfeng remembered it clearly.

Picked up the measuring tool, measured several important and key sizes, all the sizes were qualified, Li Tianfeng said: "Mr. Sun, although this batch of blades is the first batch of processing, there is a ready-made process, and the processing quality is very good, you can also take a look." ”

Sun Xiaoping also picked up the measuring tool, measured several sizes, and then said happily: "Boss, the quality of the blades is really good." ”

Li Tianfeng said: "Let's go, let's take a look at the fan casing again." ”

The turbofan 16B engine is highly similar to the turbofan 16A engine, the biggest difference is the fan part, and the fan part, fan blades and fan casing, are all different from the turbofan 16A engine.

Large casing processing workshop.

Li Tianfeng and Sun Xiaoping came to this workshop together, today, the two of them went to each workshop to take a walk, take a look, mainly to see the trial production of turbofan 16B parts, because from the beginning of the trial production to now, it has been more than a month, and the parts have basically been the first batch of trial production.

Tianfeng Technology supplies the company with several casing workshops, including large casing manufacturing workshops, mainly manufacturing large casings such as fan casings, in addition, there are small and medium-sized casing manufacturing workshops.

The two are familiar with the situation of the large casing workshop, and after entering the workshop, they walked directly to the inspection area, and saw three fan casings lined up on the inspection table.

The trial production of the three fan casings is one point faster than the progress of the fan blades, and at this time, the inspection has been completed and the transparent large plastic bag has been covered.

Next to the inspection table, an inspection technician was writing something, Li Tianfeng remembered that the inspection technician's surname was Zhao, and he was a supervisor inspection technician.

Li Tianfeng and Sun Xiaoping walked over, and Li Tianfeng said, "Zhao Gong, how is the quality of these three fan casings?" ”

When Zhao Gong saw Li Tianfeng, Ma Shan stood up, "Mr. Li, Mr. Sun, hello, I'm dealing with one of these fan casings." ”

Sun Xiaoping immediately asked with concern: "Zhao Gong, one of them has a quality problem?" ”

Zhao Gong nodded and said: "Of the three fan casings, the processing quality of two of them is completely qualified, but there is one installation hole with an out-of-tolerance position. ”

Three pieces of fan casing, two are qualified, and one is out of tolerance. This is the first batch of trial production, and it is relatively normal for there to be unqualified.

Li Tianfeng said: "Oh, I'll take a look." ”

Hearing this, Zhao Gong hurriedly gave the "substandard product tracking form" in his hand to Li Tianfeng. If the size of the parts is unqualified, it must be registered on the tracking table of unqualified products, and the slight deviation will be reviewed by the inspection technician and given treatment opinions.

If the out-of-tolerance situation is more serious, or the size of the out-of-tolerance is relatively large, it needs to be submitted to a higher level for trial, that is, the non-conforming product review committee for review.

Li Tianfeng looked at the out-of-tolerance size on this tracking table, 6 holes with a diameter of 10 mm, requiring a position degree of 5 wires, in fact, there are 7 wires, the out-of-tolerance is not very serious, and Li Tianfeng also knows that this is a general size, and the impact is not great.

Li Tianfeng said: "Zhao Gong, what are you going to do?" ”

Zhao Gong replied: "Of the three fan casings, there are only two engines installed, one of which will be used for class testing and verification, and this fan casing has an out-of-tolerance range, and I am going to downgrade it for testing and verification." ”

For the treatment of nonconforming products, there are many kinds of treatment opinions such as "use as is", "rework", "special or optional", "concession use", "downgrade use", "scrapped" and so on, among which "downgrade use" is that it cannot be installed on the engine, but can be used for some tests and verification.

Li Tianfeng nodded, this kind of handling is good, very appropriate.

Giving the tracking watch to Zhao Gong, Li Tianfeng looked at the three fan casings with great interest, and after reading them, Li Tianfeng said: "Mr. Sun, it seems that it won't be long before our turbofan 16B engine will enter the final assembly." ”

Sun Xiaoping said: "The parts of the turbofan 16B engine are processed quite well, and I estimate that it will be ten days and half a month to enter the final assembly of the engine." ”

The trial production of parts of the turbofan 16B engine has entered the final stage, and many important parts have been completed trial production, and the situation is not bad, Li Tianfeng is also very relieved.

The final assembly of the two turbofan 16B prototypes will also be a matter of the near future, the final assembly of the engine will be completed, and after the test run, it will be delivered to the Airbus Jingang manufacturing base, installed with the Airbus A320 engine, and a series of test flights and verification.

Such two turbofan 16B engines, Li Tianfeng is naturally very concerned, no, every three or five to go to the processing workshop to take a look, turn around, today, together with Sun Xiaoping, watched the processing of fan blades, fan casings, etc.

The processing of various parts is good, and Li Tianfeng is also in a good mood.

Back in his office, Li Tianfeng sat down, took a sip of tea, and thought to himself that Bombardier had sent an official fax a few days ago, and Smith and his party were coming for a business visit.

A few months ago, Smith led a team to Tianfeng Technology Company, and ordered 500 turbofan 17 engines at a price of 35.5 million yuan each.

Several months have passed, and Tianfeng Technology has also delivered 20 turbofan 17 engines per month to Bombardier in accordance with the contract, and now exactly 80 engines have been delivered, and the fifth 20 engines have been packed and ready to be shipped.

The two turbofan 18 engines have been tested and verified by Bombardier for several months, and they have performed well, and Li Tianfeng estimates in his heart that Smith will definitely order his own engines again when he comes to business this time.

Li Tianfeng thought to himself, this time, I don't know how many engines Smith will order?
