Plant E.

Since Yang Xianfeng and Liu Qingshan went to Tianfeng Technology Company last year, Factory E signed an agreement with Tianfeng Technology Company.

This is a typical contract processing.

Factory E also acted very quickly, carried out integration and reorganization in a big way, and set up three large-scale processing workshops with incoming materials, with a total of nearly 1,000 workers in the three workshops, to process parts for Tianfeng Technology Company.

Although the parts sent to factory E for processing are all general parts, they are no longer limited to rough machining, and some parts are relatively simple, and the parts with relatively low requirements are finished by factory E and processed into finished parts, and then sent to Tianfeng Technology Company.

A workshop.

This is a professional parts processing workshop, and all the parts processed are parts of Tianfeng Technology Company, which is busy.

A person who looks like a craftsman is looking at the processing of parts at the processing site, and when he sees that a certain kind of parts is being counted, he can't help but say loudly: "Master Liu, this batch of parts can't be sloppy, and the processing quality must be strictly guaranteed." ”

The master of the number car patted his chest and said: "Li Gong, don't worry, we must strictly guarantee the quality, we know that this is related to our future jobs." ”

Cheng Gang, the director of the workshop, is also inspecting the site, before, Cheng Gang was the deputy technical director of the precision machining center of the E factory, after the establishment of this workshop, he was promoted by half a level, and served as the leader of the workshop with more than 300 employees.

When I went to the inspection area, I saw that many parts had been rough-machined. It is preparing to be loaded and sent to Tianfeng Technology Company.

Cheng Gang picked up a part from one of the parts boxes and looked at it, looking at the processing pattern of the part. The condition of the burr, as well as the condition of the appearance, nod your head.

Then, several parts were spot-checked one after another, and Cheng Gang did not dare to take the processing quality of the parts lightly and has always been strict.

Suddenly. Cheng Gang's face changed slightly, because there was a small scar on the part in his hand. It should be that a collision occurred during processing or handling, and a surface defect occurred.

Cheng Gang said loudly: "What's going on, play the piano randomly!" ”

Cheng Gang was very angry and immediately ordered the parts to be re-examined. He also called the inspector in question and scolded a bloody dog.

These parts are re-inspected. Two more semi-finished parts were found to have the same scar defect, and Cheng Gang was furious and dealt with the matter severely.

Whether it is Cheng Gang, the leaders of the other two parts processing workshops also pay great attention to the quality of processing, this is because Yang Xianfeng, the number one, was in the small meeting of the conference. The product quality of OEM parts has been repeatedly emphasized, and the top leader attaches so much importance to it. Naturally, the people below also attach great importance to it.

Tianfeng Technology Company.

Today, Yang Xianfeng is a guest at Tianfeng Technology Company, and in Li Tianfeng's office, he is drinking tea and chatting with Li Tianfeng.

Yang Xianfeng thanked: "Mr. Li, you have done us a great favor this time, a large number of parts for us to process, last month our financial settlement from you more than 50 million processing payments, like this, how can there be six or seven hundred million in a year." ”

The total output value of factory E is more than 300 million yuan a year, and if there are 600 million or 700 million processing costs for Tianfeng Technology Company every year, it is a huge growth point.

Yang Xianfeng is happy!

Li Tianfeng smiled slightly, and also said: "Mr. Yang, the quality of the parts you process is good, and I am quite satisfied." ”

Factory E is an old military factory, strict quality management, coupled with the parts processed by Tianfeng Technology Company, which are basically general parts with relatively low processing difficulty, so the processing quality of the parts is relatively good.

Yang Xianfeng said: "Mr. Li, we have always put the high quality of parts processing in the first place, and we dare not relax at all." ”

Li Tianfeng said: "Mr. Yang, as long as your processing quality is stable, we can process more parts for you, and there is no problem in making more than one billion a year." ”

More than a billion!

Yang Xianfeng was very excited.

Tianfeng Technology Co., Ltd., the processing cost of outsourced parts is tens of billions of dollars every year, and it may be more this year. If factory E can ensure the quality, there should be no problem in doing more than a billion yuan.

Yang Xianfeng said: "Mr. Li, you can do so much, more than a billion!" ”

Li Tianfeng said: "If you set up one or two more specialized parts processing workshops, there is no problem in doing more than 100 million a year, you know, our Tianfeng Technology Company's goal this year is 150 billion."

Fifteen billion!

Yang Xianfeng looked at Li Tianfeng in astonishment, this is an astronomical amount in Yang Xianfeng's opinion, and the output value of Factory E in a year cannot catch up with a fraction of Tianfeng Technology Company.

Li Tianfeng nodded and said: "Last year, we received orders of 17 or 80 billion yuan, delivered more than 110 billion yuan, and 6 or 70 billion output value engines were delivered this year. ”

Tianfeng Technology Company is still booming.

At the beginning of the new year, Tianfeng Technology received orders for 300 turboshaft E from Amazonas in Brazil, as well as 200 turbofan 18 and 300 turbofan 17 orders from Embraer.

In addition, Bombardier, COMAC, Boeing, Airbus, in the first half of this year, will definitely sign orders with Tianfeng Technology, in addition to these companies, Tianfeng Technology has a big customer, that is, the military.

It is worth mentioning that the turbofan engine of Tianfeng Technology Company, whether in Boeing or Airbus, has increased its share and proportion to a certain extent.

Yang Xianfeng said: "Mr. Li, it seems that our steps are still a little more conservative, take your aircraft carrier, our E factory will set up a parts processing workshop again, and realize the rebirth of our E factory." ”

Sure enough, after Yang Xianfeng went back, he set up two specialized parts processing workshops, with thousands of employees in Factory E, and it is estimated that nearly 2,000 people are specialized in the processing of parts of Tianfeng Technology Company.

A few years later, the processing of parts for Tianfeng Technology Company has become the main business of Factory E, and the annual output value of Factory E has also risen from more than 30 billion yuan to more than 40 or 50 yuan, and finally has been stable at about 10 billion yuan.

Tianfeng Technology Company.

Aero Engine R&D Center.

Li Tianfeng on the computer, carefully looking at some parts that have been designed, the turbofan 25 engine has entered the full design for several months, and many parts have been designed.

On the computer, the three-dimensional turbine rotor looks very beautiful, and after looking at it, Li Tianfeng began to simulate.

Using professional software, after entering the parameters, the turbine rotor rotates, gradually faster and faster, the software shows the temperature field, the force of the turbine is also displayed, the darker the color of the turbine, the greater the force.

When the turbine rotor reaches the design speed, it rotates at a speed of tens of thousands of revolutions, the temperature field stabilizes, and the force on the turbine also stabilizes.

Li Tianfeng said: "The turbine design is very good, you see, it is basically within the scope of our design. ”

Standing next to him were Sun Xiaoping, Qiu Wenan and others, Sun Xiaoping said: "Boss, the design of the turbine rotor, under your guidance, we have revised it three times, and now it has finally met the design expectations." ”

Li Tianfeng finished reading the design of the turbofan 25 engine turbine rotor, and then got up and said: "Let's go, let's take a look at the low fatigue cycle test of the fan blades of our turbofan 21 engine." ”

The turbofan 21 engine has been in full trial production for several months, and many parts have begun to enter various tests and verifications after completing the processing verification, such as the low fatigue cycle test.

We walked into a certain laboratory, where the fan blades of the turbofan 21 engine were being tested on a test bench for low cycles.

The fan blades of the turbofan 21 engine, the wide chord blades of the "Hercules" material, each blade is very wide, and the blade shape is very beautiful, but the blade type is obviously different from the fan blades of the turbofan 16 and other engines.

The fan blades of the turbofan 21 engine adopt a more advanced and better blade design, which has better aerodynamic performance and better efficiency.

If it is a titanium alloy wide-chord hollow blade, Li Tianfeng really does not dare to adopt such a blade design, because, with such a blade design, the fan blade is more efficient, but it also means that it will be subjected to a greater load, and the titanium alloy wide-chord hollow blade is embarrassed by such a heavy burden.

The wide-chord fan blades of the "Hercules" material do not have a problem, because the strength of this material is much higher than that of titanium alloy, and it is completely competent.

The fan blades have good aerodynamic performance and high efficiency, which means that the fan has higher efficiency and can also provide greater thrust, which is also one of the advanced aspects of the turbofan 21 engine.

At present, it must be determined how well the wide-chord fan blades of this material are resistant to fatigue.

The fan blades are required to have excellent fatigue resistance, otherwise, if there is a crack in the process of use, it will be a serious accident, and if it is not done well, the machine will be destroyed and people will die.

Li Tianfeng walked to the side of the test bench, looked at the fan blades that were undergoing low-cycle fatigue tests, and looked at the test data on the LCD screen, including the number of force cycles and so on.

Seeing that the number of stress cycles had reached a very high number, Li Tianfeng knew that this blade would soon be removed from the test bench.

Come here to take a look at the low-cycle fatigue test, Li Tianfeng has been here several times, and this fan blade has also been tested on the test bench for a long time, and the results will be available soon.

Suddenly, the test equipment alarmed, and on the display screen, a red warning sign flashed and flashed.

Seeing this situation, Li Tianfeng knew that there was a problem with the low-cycle fatigue test of the fan blades.
