e Factory.

Since Yang Xianfeng and Liu Qingshan went to Tianfeng Technology Company last year, e Factory has signed an agreement with Tianfeng Technology Company. After the agreement was signed, a large number of parts were sent to e Factory for processing in batches.

This is a typical incoming material processing.

Factory e also acted very quickly, and carried out drastic integration and reorganization, forming three large incoming materials processing workshops. There were nearly a thousand workers in the three workshops to process parts for Tianfeng Technology Company.

Although all the parts sent to factory e are general parts, they are no longer limited to rough processing. Some parts that are relatively simple and have relatively low requirements are finished by factory e to complete the finished parts and then sent to Tianfeng Technology Company.

A workshop.

This is a professional parts processing workshop, and all the parts processed are from Tianfeng Technology Company. Here, it is busy.

A man who looks like a craftsman was watching the processing status of parts on the processing site. When he saw a certain part being counted, he couldn't help but say loudly: "Master Liu, this batch of parts cannot be careless, and the processing quality must be strictly guaranteed."

The master of the counting car patted his chest and said, "Mr. Li, don't worry, we must strictly ensure the quality. We know that this is related to our future job."

The workshop director Cheng Gang is also on-site inspection. In the past, Cheng Gang was the technical deputy director of the precision machining center of the e-plant. After the establishment of this workshop, he was promoted to half a level and served as the head of the workshop with more than 300 employees.

When I inspected the inspection area, I saw that many parts had been roughly processed and were about to load and sent to Tianfeng Technology Company.

Cheng Gang picked up a part from one of the parts boxes and looked at the processing patterns, burrs, and appearance conditions of the parts, and nodded.

Then, several parts were checked one after another, and Cheng Gang did not dare to take it lightly at all and always strictly required it.

Suddenly, Cheng Gang's face changed slightly because there was a small scar on the part in his hand, which should have collided during processing or handling, and surface defects appeared.

Cheng Gang said loudly: "What's going on? Playing the piano randomly!"

Cheng Gang was very angry and immediately ordered the parts to be re-inspected. He also called the inspector involved over and scolded him.

These parts were re-examined and found that the two semi-finished parts had the same scar defect. Cheng Gang was so angry that he dealt with this matter severely.

Whether it is Cheng Gang or the leaders of the other two parts processing workshops also pay great attention to processing quality. This is because Yang Xianfeng, the top leader, repeatedly emphasized the product quality of the parts processing at the conference. At the top leader attaches so much importance to it, the people below naturally attach great importance to it.

Tianfeng Technology Company.

Today, Yang Xianfeng was visiting Tianfeng Technology Company and was having tea and chatting with Li Tianfeng in Li Tianfeng's office.

Yang Xianfeng thanked: "Mr. Li, you have helped us a lot this time. A large number of parts are processed for us. Last month, our finance department settled more than 50 million in processing payments from you. If this continues, there will be 600 million or 700 million in a year."

The total output value of factory e is only more than 3 billion yuan per year. If Tianfeng Technology Company can produce 600 million or 700 million yuan in processing parts every year, it will be a huge growth point.

Yang Xianfeng is happy!

Li Tianfeng smiled slightly and said, "Mr. Yang, the parts you processed are of good quality, and I am quite satisfied with them."

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

Yang Xianfeng said: "Mr. Li, we have always put the high quality of parts processing first, 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 it will be fine to make more than one billion a year."

More than one billion!

Yang Xianfeng was very moved.

Tianfeng Technology Company has a processing cost of over 10 billion yuan for outsourced parts every year, and there may be more this year. If the e-factory can ensure quality, it should be no problem to make more than 1 billion yuan.

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

Li Tianfeng said: "If you set up another two professional parts processing workshops, it will be fine to do more than one billion a year. You should know that our Tianfeng Technology Company's goal this year is 150 billion.

One thousand five hundred billion!

Yang Xianfeng looked at Li Tianfeng in shock. In Yang Xianfeng's opinion, this is an astronomical figure, and the annual output value of e-factory cannot keep up with a fraction of Tianfeng Technology Company.

Li Tianfeng pointed out: "Last year, we received orders of 170 billion to 80 billion, delivered more than 110 billion, and there are also engines with output value of 600 billion to 70 billion this year. In addition, we signed orders of 100 billion this year, and the orders in our hands have approached 100 billion, and we must start production at full capacity."

Tianfeng Technology Company is still in full swing.

At the beginning of the new year, Tianfeng Technology Company received orders for 300 turboshaft e of Brazilian Amazon, as well as orders for 200 turbofans 18 and 300 turbofans 17 of Embraer.

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

It is worth mentioning that Tianfeng Technology's turbofan engine, 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 conservative. With your aircraft carrier, our e-factory will set up a parts processing workshop to achieve the rebirth of our e-factory."

Sure enough, after Yang Xianfeng returned, he established two professional parts processing workshops. There were thousands of employees in the e-factory, and it is estimated that nearly 2,000 people specialized in the processing of parts of Tianfeng Technology Company.

Several years later, processing parts for Tianfeng Technology Company became the main business of e-factory. The annual output value of e-factory also increased from more than 3 billion to more than 40 and fifty, and finally stabilized at a scale of about 10 billion.

Tianfeng Technology Company.

Aero Engine R&D Center.

Li Tianfeng was on the computer and was carefully looking at some parts that had been completed. It has been months since the turbofan 25 engine entered the comprehensive design, and many parts have been designed.

On the computer, the three-dimensional turbo rotor looks very beautiful. After watching it, Li Tianfeng began to simulate and simulate.

Professional software is used. After inputting parameters, the turbine rotor rotates and gradually rotates faster and faster. The software displays the temperature field and the force of the turbine is also displayed. The darker the part of the turbine color, the greater the force.

The turbine rotor reaches the designed speed and rotates at a speed of tens of thousands of revolutions per minute. The temperature field stabilizes and the force of the turbine stabilizes.

Li Tianfeng said: "The turbine design is very good. You see, it is basically within our design range."

Next to him were Sun Xiaoping, Qiu Wen'an and others. Sun Xiaoping said: "Boss, under your guidance, we have modified the design of the turbine rotor three times, and now we have finally met the design expectations."

After seeing the design of the turbine rotor of the turbofan 25 engine, Li Tianfeng stood up and said, "Let's go and 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. After completing the processing and verification, many parts begin to enter various tests and verifications, such as low fatigue cycle tests.

Everyone walked into a laboratory where the fan blades of the turbofan 21 engine were undergoing low-cycle tests on the test bench.

The fan blades of the turbofan 21 engine and the wide-string blades of the "Hercules" material, each blade is very wide and the blade shape is very beautiful, but the blade shape is obviously different from the fan blades of the engine such as the turbofan 16.

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

If it is a titanium alloy wide-string hollow blade, Li Tianfeng really dares not adopt such a leaf design, because using such a leaf design will make the fan blade more efficient, and it also means that it will be subject to greater loads. The titanium alloy wide-string hollow blades are embarrassed by such a heavy burden.

There is no problem with wide-string fan blades of "Hercules" material, because the strength of this material is much higher than that of titanium alloy and is completely competent.

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

At present, what must be determined is how fatigue-resistant the wide-string fan blades of this material are.

Fan blades require excellent fatigue resistance. Otherwise, cracks appear during use, which will be a serious accident. If the aircraft is damaged, the person will die.

Li Tianfeng walked to the test bench, looked at the fan blade that was undergoing a low-cycle fatigue test, and then looked at the various test data on the LCD screen, including the number of stress cycles, etc.

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

Come here to see the low cycle fatigue test. Li Tianfeng has been here several times. This fan blade has been tested on the test bench for a long time and results will be obtained soon.

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

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