Li Tianfeng, Zeng Qinghai, followed by a process supervisor of the process technology department, and a supervisor technician in the blade processing workshop, everyone is walking over here, Li Tianfeng's purpose here is to take a look at the processing of these fan blades.

Walking straight to the front of the vertical machining center of the rough milling fan blades, Li Tianfeng looked at the processing situation and picked up one of the rough machined blades.

Because it is made of titanium alloy, although the blade is relatively large, the weight is not very heavy, Li Tianfeng looks at the processing pattern of the blade, according to Li Tianfeng's level, through the guò processing texture can see a lot of things.

After looking at it, Li Tianfeng said with satisfaction: "Master Tang, the processing is good." ”

Master Tang, a middle-aged worker, smiled happily: "Mr. Li, this material is relatively easy to process, and the CNC program is also well prepared, and the processing is relatively smooth, but there are still a few problems that need to be improved." ”

On the work table next to it, there is a blank paper process specification, this number of milling processes, with a pen, or ballpoint pen, changed a lot of places, and also wrote a lot of text, some of the things that need to be improved, the places that need to be paid attention to are recorded on it.

Every place that has been changed, there is the signature of the process technician, and there is also the year, month and day, this is a kind of technical management of Tianfeng Technology Company, the processing of parts of a new aero engine, the processing of several batches of the first few rounds, are all this kind of white paper process procedures, and the problems found are recorded on it one by one.

Each time a batch of processing is completed, the process technicians will improve and improve the processing technology according to the problems found and the processing of this batch of parts. There will be fewer and fewer problems, the processing will be smoother and smoother, and the machining quality of the parts will be better and better.

Li Tianfeng flipped through the process regulations for printing on white paper, nodded with satisfaction, and said to the technician in charge next to him: "Xiao Wang, you did a good job." ”

Get praised. Xiao Wang, the technician in charge, was inexplicably happy in his heart.

In this vertical machining center, we watched the rough machining of these blade blanks, and then we walked to the vertical five-axis linkage CNC grinder not far away, which is a high-precision, high-speed grinding machine, which is grinding fan blades.

There are several blades that have been processed, and after finishing, the blades are very beautifully processed, not only the surface of the blades is smooth. It has a metallic luster unique to titanium alloy, and the leaf shape is also very beautiful, and each piece is already very thin and light.

Li Tianfeng picked up the two pieces and put them together, the two blades were exactly the same, and together they were a whole piece, the fan blades of this turbofan engine. It is two blades, one concave. A convex surface, which forms the leaf basin and the leaf back, will be honeycomb in the middle, which is welded together by a welding process.

The two pieces together are exactly the same, very beautiful. Li Tianfeng said with satisfaction: "Take a look, the processing is very good!" ”

Zeng Qinghai also said: "Boss, although this kind of blade is designed to be very advanced, the craftsmanship is very good, and the processing is not as big as imagined." ”

Li Tianfeng said: "Each of our engines. When designing, the manufacturability is fully considered, and such parts, after processing a few more batches, will only become more and more smooth. ”

After a pause, Li Tianfeng said: "These fan blades have completed CNC machining, but only half of the processing has been completed, and the subsequent welding is a very critical process." ”

Zeng Qinghai said: "Boss, we have made a few test pieces, ready to start the welding test, and then weld these formal blades after success." ”

Generally speaking, some of the more critical parts, especially some new parts, are often tested with test pieces when they are processed for the first time, especially when it comes to new processes.

Li Tianfeng looked at the processing of these fan blades in detail in the blade processing workshop, and was more satisfied, and at the same time had a detailed understanding of the processing situation.

According to the technical strength and process technology level of Tianfeng Technology Company, Li Tianfeng is full of confidence in this turbofan engine.

Turbofan engine, generally speaking, the development and manufacturing difficulty of medium and small engines is smaller than that of large turbofan engines.

Such an engine, although the design performance is very good, is definitely the best in the same class of fourth-generation turbofan engines, but compared with large turbofan engines, such as Airbus A380, Boeing 777 and other passenger aircraft large turbofan, the development and manufacturing of is less difficult.

………

In the past few days, Li Tianfeng's main energy is basically on the development of this turbofan engine, and some key and key parts are even checked personally, but he will also pay attention to the production of turboshaft D engine and the test run of turboshaft E engine.

Today's "Songzhou Daily" is on the front page, full of pictures and texts, and a large and enthusiastic report on the turboshaft E engine.

The title of "Turboshaft E engine starts 3000 hours life test" is very eye-catching, and what is even more eye-catching is that there are also color photos of the turboshaft E engine, which immediately attracted the attention of many people.

"This is Tianfeng Technology's second turboshaft engine, which is amazing!"

"In such a short period of time, the second turboshaft engine has actually begun to test its life, Tianfeng Technology Company!"

"Yes, it's still a 3,000-hour life test, which is amazing!"

"Tianfeng Technology Company, the pride of our Songzhou!"

“”

Tianfeng Technology's second turboshaft engine began to test its life, the report of "Songzhou Daily" caused a small storm in the entire Songzhou City, many citizens after tea and dinner, work and leisure, everyone talked about the most topic is Tianfeng Technology Company.

"Old Song, I heard that Tianfeng Technology Company is still developing a turbofan engine, and it is also a very advanced turbofan engine."

"Yes, I've heard about it too, but I don't know what kind of engine it is, and Tianfeng Technology's secrecy is very strict."

"I'm really looking forward to it, it's actually a turbofan engine!"

“……”

Not only the general public is hotly discussed, at a meeting of the Songzhou Municipal Government, near the end of the meeting, Guo Tongde actually mentioned Tianfeng Technology Company, as a mayor, at the mayor's office meeting, it can be seen that Tianfeng Technology Company is in Guo Tongde's mind.

Guo Tongde said happily: "Comrades, I have good news for you, Tianfeng Technology's second turboshaft engine, that is, the turboshaft E engine, has started a 3,000-hour life test!" ”

"Ahh That's fast! ”

"Tianfeng Technology Company, it's really amazing!"

Everyone who attended the meeting, especially the deputy mayors, was surprised and surprised. Some people even think in their hearts that if they have the opportunity, they must go to Tianfeng Technology Company to have a look and take a walk.

Guo Tongde saw that everyone was surprised, and couldn't help but say: "I believe everyone is very happy with such good news, and I am the same, I have been happy for a long time when I heard such good news." ”

"Mayor Guo, this is really good news, it seems that we will soon have a second advanced turboshaft engine in Songzhou."

"Yes, Tianfeng Technology Company really impresses us!"

“……”

Several deputy mayors, and bursts of praise and emotion, even, everyone's heart is slightly excited, Tianfeng Technology Company is so powerful, everyone here knows that their career may also be stained with the light of Tianfeng Technology, I heard that Mayor Guo can rise one step further, it is because of Tianfeng Technology Company.

Guo Tongde couldn't help but look at everyone's thoughts, and he understood it very well in his heart, Guo Tongde smiled heartily and threw out another bombshell.

"Comrades, I would like to tell you a better and more exciting news, Tianfeng Technology Company has been developing a very excellent turbofan engine, and has entered the stage of comprehensive detailed design, this is a fourth-generation turbofan engine!"

What the!

Excellent turbofan engine!

Fourth-generation engines!

Everyone, you look at me, I look at you, and find that the other party's eyes are full of shock, this is completely a bombshell, "boom", will blow up for a long time and can't come back to their senses.

"Bang!"

One of the deputy mayors, when he picked up his teacup and was about to take a sip of water, his hands trembled slightly because of excitement, and he didn't hold it steady for a while, and the teacup actually fell to the ground.

Seeing this, Guo Tongde smiled happily, and thought in his heart, Tianfeng, you are a cow! It's awesome to make our deputy mayor so out of shape!

………

Tianfeng Technology Company.

In his office, Li Tianfeng was reviewing a design drawing, when he suddenly sneezed, and thought to himself, who is talking about me!

Li Tianfeng smiled slightly, then looked at the design drawing again, picked up the pencil, and revised and modified the design drawing printed on the white paper, and after making some changes, Li Tianfeng put down his pencil with satisfaction.

This turbofan engine, Li Tianfeng has high hopes, for some key parts, key parts, do not dare to take it lightly, personally check, the design drawings of these parts, after the completion of the design, all sent to Li Tianfeng.

Li Tianfeng patiently reviewed them one by one, and marked out some of the things to be modified and improved on the design drawings one by one.

After some revisions, I put away the design drawings, and there was a knock on the door.

As soon as Li Tianfeng heard the rhythm and strength of the knock, he knew that it was definitely not Liu Wei, and Li Tianfeng said loudly: "Please come in!" ”

………

Today's two shifts, the second shift is complete!

I had a day's meeting today, and my head was dizzy, so I could only watch two more, sorry! (To be continued......)
