Everyone was surrounded by this aircraft engine and was slightly excited. This was the first turbofan engine of Tianfeng Technology. Even if it was just an exhibition machine, the physical engine was placed in front of everyone and it felt absolutely different.

Liu Wei took a camera and took photos from several angles, taking pictures of the turbofan engine that had just been installed.

The engine has a large head, a thin waist, and a small butt. The typical large channel is more than a turbofan engine. It makes people look at it forever and is very attractive.

“So beautiful, so exquisite!”

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

"Well, the performance is good, it's very attractive!"

When everyone looks at this engine, the overall appearance is very good. Whether it is the shape or the specific details, it is very good. It looks very beautiful and exquisite as a high-end and high-quality aircraft engine.

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

Liu Wei was also very happy. She held the camera with great enthusiasm, took a lot of photos, and said loudly: "Xiao Liu, take a photo for me!"

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

Seeing this, Li Tianfeng smiled and could see how happy Liu Wei was at the moment, and the rest of the people were the same.

Xu Lilong said: "Boss, the first engine has been installed as a whole. It's really exciting and inspiring!"

Sun Kang also said: "Yes! This is absolutely milestone, our first turbofan engine. How beautiful it is, and I feel a sense of accomplishment in my heart."

Li Tianfeng, Xu Lilong and Sun Kang, as the company's senior management, stood a little further away from the engine. It was several meters away, and some technicians could not hold back and surrounded the engine and were happy and excited to discuss it.

Some people even looked here and there happily. When they couldn't help but touched them gently.

Seeing everyone's appearance, Li Tianfeng smiled and said, "The only drawback is that our second exhibition machine, that quarter-quarter cutting machine, is still missing a few important parts, otherwise, we can start assembly."

Xu Lilong nodded and said, "If both engines come out, sway here and line them up side by side, that's what it's like to attract attention."

Sun Kang said: "That's right, such a large channel is so beautiful than a turbofan engine. I believe that anyone who sees these two engines will definitely not help but come over and take a closer look."

Li Tianfeng clicked a little and said, "When we strive to enter the final assembly within a week, our second exhibition aircraft will start to enter the final assembly. Time will not wait for anyone. It is now the end of October, and it is less than a month since the official air show."

Sun Kang looked stern: "Even if we work overtime and do all night, we must get out the missing items as soon as possible."

Li Tianfeng said: "The most difficult thing about these missing parts is our composite fan receiver, which is a big guy. The difficulty of manufacturing this part is definitely the biggest among these missing parts."

Sun Kang nodded and fully agreed with this.

The fan receiver has a diameter of more than 1.5 meters and is a large thin-walled cylinder, but this is definitely not a simple thin-walled cylinder with a complex structure and has many precision installation holes, bosses, installation surfaces, etc.

An aircraft engine can be seen from the specific gravity of new materials such as titanium alloy materials, composite materials, ceramic materials, etc. Its advanced nature and excellent comprehensive performance.

For relatively old aircraft engines, titanium alloy materials are rarely used and there are almost no new materials. With the development of technology, titanium alloy materials have begun to appear in aircraft engines, and their proportion has gradually increased from less than 10%, 20%, 30%.

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

This turbofan engine of Tianfeng Technology Company widely uses titanium alloy materials and various new materials, which account for a proportion of more than 50%. The new materials also include various composite materials, ceramic materials, as well as single crystal materials, powder metallurgy high-temperature alloys, etc.

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

It was already 12 o'clock in the evening, but everyone was still very motivated because the processing of this fan receiver had been completed and the final inspection procedure began to enter.

It is not easy to process such a receiver. It took several nights and three shifts without stopping at all. The purpose is to make this part as soon as possible and install the second exhibition machine as soon as possible.

The several craftsmen who were responsible for processing the entire receiver only breathed a sigh of relief at this moment, feeling relieved.

The two inspectors carefully inspected the receiver with various measuring tools. The appearance inspection was completed at the beginning. The appearance was very beautiful and flawless.

Lao Zheng, the chief craftsman, felt relieved and quietly looked through the thick white paper process rules in his hand. In this process rules, almost every process was changed and he wrote a lot of things.

This fan receiver is the second batch. Although there is only one in number, a series of process problems found during the processing process have been recorded. This process regulation will definitely be improved again, especially some process parameters and process steps will be improved and improved.

"It's really not easy!" Lao Zheng thought to himself.

In fact, Lao Zheng is not old, he is only in his thirties, but because he is a senior engineer, he is considered to be relatively old among the 20 or 30 craftsmen in the receiver manufacturing workshop, and everyone is used to calling him "Lao Zheng".

"Old Zheng, this receiver looks good. In addition, our designers are so awesome. Such a large receiver is not only designed so beautifully, but also not heavy at all. I just easily moved this receiver to the inspection platform alone."

Seeing Xiao Zhang next to him with a happy look, Lao Zheng smiled happily, and then said, "I heard that at the beginning of the design of this receiver, Mr. Li personally drew a sketch. The designers of the design institute developed the design based on Mr. Li's sketch, so that such an advanced fan receiver was found."

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

Another craftsman next to him said: "No wonder, although this receiver is a thin-walled large complex structure receiver with high accuracy requirements, the processability is not bad. On the contrary, the processability is very good. Otherwise, we would not have imagined to be made so smoothly. It turned out that Mr. Li drew a sketch in advance."

While chatting, we waited for the inspection results. When the time pointed to two in the morning, the inspection of this receiver had basically been completed.

On several actual measured value record tables, each size and technical conditions of this receiver are recorded in detail one by one, and several unqualified sizes are also specially marked.

One of the inspectors said: "Mr. Zheng, this is the inspection result. The quality of the receiver is pretty good, and only a few are slightly unqualified in general sizes."

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

Several of the general sizes are slightly unqualified and do not matter and do not affect the use of this receiver, because Lao Zheng knew that this receiver was installed on the second exhibition machine and was only used for exhibition.

Several craft technicians next to them also gathered around. After seeing the results, everyone looked happy on their faces.

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

"Yes, it means that our craftsmanship is OK. Only a few of the general sizes are not up to standard, which is completely beyond my expectations."

Everyone was looking happy, and Li Tianfeng walked over quickly with Zeng Qinghai, the director of the receiver workshop and the technical director.

It was already early morning, and without thinking, Li Tianfeng came to the workshop. Suddenly, everyone looked excited, especially when they saw Li Tianfeng walking over quickly, the excitement on everyone's face became even more obvious.

Li Tianfeng walked to the inspection platform and looked at the receiver. He couldn't help but think in his heart, it was beautiful, very beautiful and exquisite.

After looking at these process technicians with praise, Li Tianfeng asked: "Have the inspection results come out? How is the quality?"

He quickly handed the inspection results to Li Tianfeng, and Lao Zheng said: "Mr. Li, the processing quality of the receiver is good, and only a few of them are not qualified in general sizes."

Li Tianfeng looked at the inspection records enthusiastically and said happily: "It's not bad, all the important and key sizes and technical conditions are qualified, which is very rare. This is just the second batch of fan receivers we processed. It can achieve such quality, which means that you have put a lot of thought into it."

Xiao Zhang next to him said, "Mr. Li, our Zheng craftsman has spent a lot of effort. He has been doing all night in the past few days, and our processing technology has been continuously optimized and improved."

"Oh." Li Tianfeng was very happy. After taking the blank paper process regulations, he looked through it a little, Li Tianfeng said: "You did a good job and recorded it in very detailed. You have recorded all the problems exposed during the processing process."

Each batch of parts is tracked from beginning to end, and problems in the processing process are recorded one by one. After the batch of parts are processed, the processing technology is improved in combination with these problems. This is the tradition of Tianfeng Technology Company.

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

However, it is very obvious that Lao Zheng has done more well in this regard and has thought a lot. The processing of the second batch of fan receivers has reached such a level, and the processing quality is perfect.

Li Tianfeng waved his hand happily and said, "Mr. Zeng, what are the rewards we bring to you!"
