Everyone gathered in front of this aero engine, slightly excited, this is the first turbofan engine of Tianfeng Technology Company, even if it is only an exhibitor, but the physical engine is placed in front of everyone, and it feels absolutely different.

Liu Wei took a camera and took pictures from several angles to take pictures of the turbofan engine that had just completed the final assembly.

The engine head is large, the waist is thin, the butt is small, and the typical large channel is larger than that of a turbofan engine. No matter how you look at it, you will never get tired of looking at it, and it is very attractive.

"It's beautiful, it's exquisite!"

"Yes, I think the quality is super good at first glance!"

"Well, it looks good, it's very attractive!"

Everyone looks at this engine, especially the overall appearance is very good, whether it is the shape, or the specific details, it is very good, at first glance, it is very beautiful and exquisite of high-end and high-quality aero engines.

Li Tianfeng also said happily: "Yes, this is like the turbofan engine produced by our company!" ”

Liu Wei was also very happy, took the camera with great interest, took a lot of photos, and said loudly: "Xiao Liu, take a picture for me!" ”

The beautiful Xiao Liu is a supervisor of the administration department and immediately took the camera, while Liu Wei posed on the front of the Thai engine, clenched her fists and stretched out her arms, and a shape representing this strength and encouragement was frozen.

Seeing this, Li Tianfeng smiled, and it could be seen how happy Liu Wei was at the moment, and the rest of the people were not.

Xu Lilong said: "Boss, the first engine is finally assembled, which is really exciting and inspiring!" ”

Sun Kang also said: "Yes! This is definitely a milestone, our first turbofan engine, how beautiful, and I feel a great sense of accomplishment. ”

Li Tianfeng, Xu Lilong. Sun Kang and the three, as the company's senior executives, stood a little farther away from the engine, several meters away, and some technicians couldn't hold it anymore and surrounded the engine. Happy and excited.

Even, some people are happy to take a look here, take a look there, and when they can't help it, they also touch it gently.

Seeing everyone's appearance, Li Tianfeng smiled, and then said: "The fly in the ointment is that our second exhibitor is the quarter of the cutting machine. So far, there are still a few important parts missing, otherwise, the final assembly can also begin. ”

Xu Lilong nodded and said: "If the two engines come out, swing here, and side by side, then it is called eye-catching." ”

Sun Kang said: "That is, such a big letter is more beautiful than a turbofan engine." I believe that anyone who sees these two engines. I'm sure I can't help but come over and take a closer look at it curiously. ”

Li Tianfeng nodded, and then said: "Strive for a week, our second exhibitor began to enter the final assembly, time waits for no one, it is now the end of October, less than a month away from the official air show." ”

Sun Kang's expression was awe-inspiring: "Even if you work overtime." All night, we have to do our best to get out of those few missing pieces. ”

Li Tianfeng said: "The most difficult of these missing parts should be our composite fan casing, which is a big guy, and the manufacturing difficulty of this part." Of these, it is certainly the largest of these deficiencies. ”

Sun Kang nodded, fully agreeing with this.

The fan casing, with a diameter of more than one meter five, is a large thin-walled cylinder, but this is definitely not a simple thin-walled cylinder, with a complex structure, and there are many precision mounting holes, bosses, mounting surfaces, etc.

An aero engine, from the proportion of titanium alloy materials, composite materials, ceramic materials and other new materials can be seen its advanced and excellent comprehensive performance.

With the development of technology, titanium alloy materials began to appear in aero engines, and the proportion gradually increased from less than 10%, 20%, 30%

Modern advanced aero engines not only widely use titanium alloy materials, but also use new materials more extensively, and the proportion of these materials even reaches more than 50%.

Tianfeng Technology's turbofan engine widely uses titanium alloy materials, as well as a variety of new materials, which account for more than 50%, including various composite materials, ceramic materials, as well as single crystal materials, powder metallurgy superalloys and so on.

………

Tianfeng Technology Company, the casing manufacturing workshop, is brightly lit.

It was past 12 o'clock in the evening, but everyone was still full of energy, because the processing of this fan casing had been completed and the final inspection procedure began.

It is not easy to process such a machine box, several overnight, three shifts, without stopping at all, in order to make this part as much as possible, and install it on the second exhibition machine.

Several technicians who are responsible for the processing of the whole casing are only slightly relieved at this moment, and there is a sense of relief.

Two inspectors, holding various measuring tools, carefully inspected the casing, and the visual inspection had been completed at the beginning, and the appearance was very beautiful and flawless.

Lao Zheng, the technician in charge, breathed a sigh of relief in his heart, and quietly looked through the thick white paper process regulations in his hand.

This fan casing is the second batch, although the number is only one, but in the process of processing, a series of process problems found are recorded, this process specification will definitely be improved again, especially some process parameters and process steps will be perfected and improved.

"It's not easy!" Lao Zheng thought in his heart.

In fact, Lao Zheng is not old, only in his thirties, but because he is a senior engineer, he is relatively old among the twenty or thirty craftsmen in the casing manufacturing workshop, and everyone is used to calling him "Lao Zheng".

"Lao Zheng, this casing looks good, in addition, our designers are really good, such a large casing, not only is it so beautifully designed, but also the weight is not heavy at all, just now I easily moved this casing to the inspection platform."

Seeing Xiao Zhang next to him with a happy face, Lao Zheng also smiled happily, and then said: "I heard that at the beginning of the design of this case, Mr. Li personally drew a sketch, and the designers of the design institute carried out the design according to Mr. Li's sketch, so that there was such an advanced fan case. ”

Xiao Zhang said: "No wonder, Mr. Li's technical level, I admire it so much." ”

Another technician next to him said: "No wonder, although this casing is a thin-walled large complex structure casing, the accuracy requirements are very high, but the manufacturability is not bad, on the contrary, the manufacturability is very good, otherwise, we don't want to make it so smoothly, it turned out that Mr. Li drew a sketch in advance." ”

Everyone chatted while waiting for the inspection results, and when the time pointed to two o'clock in the morning, the inspection of the receiver was basically completed.

On several measured value record sheets, every size and technical condition of this casing are recorded in detail one by one, and several unqualified dimensions are specially marked.

One of the inspectors said: "Zheng Gong, this is the result of the inspection, the quality of the receiver is not bad, only a few general sizes are slightly unqualified." ”

Lao Zheng took the inspection record, looked at it carefully, and saw that some important key dimensions and some important technical conditions were all qualified, and he couldn't help but feel happy.

A few general sizes are slightly unqualified, irrelevant, and do not affect the use of this casing, because Lao Zheng knows that this casing is installed on the second exhibition machine, only for the exhibition.

Several process technicians next to him also gathered around, and after everyone saw the results, their faces were happy.

"Lao Zheng, the quality of the receiver is good!"

"Yes, it means that our process is okay, only a few general sizes are unqualified, which is completely beyond my expectations."

Everyone was happy, and saw Li Tianfeng walking over briskly, accompanied by Zeng Qinghai, the director of the receiver workshop, and the technical director.

It was already early in the morning, I didn't think about it, Li Tianfeng also came to the workshop, and suddenly, everyone's face was excited, especially when they saw Li Tianfeng walking over quickly, the excited look on everyone's face was even more obvious.

Li Tianfeng walked to the inspection platform, looked at the machine box, and couldn't help but secretly say in his heart, beautiful, really beautifully processed, very beautiful and exquisite.

Glancing approvingly at these process technicians, Li Tianfeng asked, "Are the inspection results out?" What about the quality? ”

Hurriedly handed the inspection results to Li Tianfeng, and Lao Zheng said: "Mr. Li, the processing quality of the casing is good, only a few general sizes are unqualified." ”

Li Tianfeng looked at the inspection records with great interest, and said happily: "Yes, the important and key sizes, and the technical conditions are all qualified, which is very rare, this is only the second batch of fan casings we processed, and it shows that you usually use a lot of thought." ”

Xiao Zhang next to him said: "Mr. Li, our Zheng Gongke has spent a lot of thought, and in the past few days, we have been doing a few all-nighters, and our processing technology has been continuously optimized and improved." ”

"Oh." Li Tianfeng was very happy in his heart, took this white paper process manual, and after flipping through it slightly, Li Tianfeng said: "You have done a good job, and the records are also very detailed, and you have recorded the problems exposed in the processing process." ”

Each batch of parts processing, are tracked from beginning to end, the problems in the processing process are recorded one by one, after the processing of this batch of parts, combined with these problems to improve the processing technology, this is the tradition of Tianfeng Technology Company.

In this way, after three or five batches of trial production and processing of parts, the process will be more and more perfect, more and more mature, and the processing quality of parts will be better and better.

It's just that it is very obvious that Lao Zheng has done a better job in this regard, and he has used a lot of brains to process the second batch of fan casings, and the processing quality is perfect.

Li Tianfeng waved his hand happily and said, "Mr. Zeng, what about the rewards we brought, give them to everyone!" ”
