Li Tianfeng is very experienced in bearings. Because the bearings are in a decomposed state, Li Tianfeng put away a ball of the main bearing, looked at it carefully, and also held a small flashlight to shine the balls, using the strong light to make it clearer.

After looking at it, Li Tianfeng nodded. The ball was not abnormal at all. The surface was very bright, and there was no slight scratch, which looked very comfortable.

After looking at a lot of balls and the inner and outer rings of the bearings, Li Tianfeng looked at them very carefully and did not find any abnormalities.

After looking at multiple bearings in succession, Li Tianfeng nodded slightly. Although domestic bearings are slightly worse in quality than imported ones, they have taken many considerations in designing them, which can greatly make up for this.

After reading a few important bearings, Li Tianfeng looked at the outer ring of the turbine. The outer ring of the turbine is sealed with metal honeycombs. When the engine is working, the gap between the tip of the turbine blade and the outer ring of the turbine is only ten lines. Of course, this is a theoretical design. During actual work, the gap may be smaller or larger.

If the gap is small, the tip of the leaf may rub against the honeycomb, which will cause certain wear on the peaks. Slight wear is allowed, but severe wear is absolutely not allowed.

The outer ring of the free turbine is added with two-stage gas turbine outer ring, and there are three stages in total. Each stage has 12 outer rings. Li Tianfeng picked up one and looked carefully. This outer ring of the turbine is 8 long, 8 wind, 8 literature, 8 science, √⊥t hole is good, and there is no wear.

After looking at several pieces in a row, no wear occurred. Li Tianfeng nodded slightly. The design of this engine is quite good. He carefully looked at all thirty-six pieces of the three-stage turbine outer ring, but most of them did not wear. Only three pieces showed very slight wear, which was so normal that it could not be normal.

After looking at the honeycombs on the outer ring of the turbine, Li Tianfeng looked at the grating teeth on the turbine disc. These grating teeth are also used to seal them to allow certain wear.

Similarly, because the design is good, and after reasonable and sufficient calculations during design, the grate teeth on the turbine disc are basically not worn, or are very slightly worn, completely within the normal range.

After reading the comb teeth, Li Tianfeng looked at many important and critical parts. Without exception, there were basically no problems. Even if there were any minor problems, they were completely within the normal range.

Three days later, all parts were inspected and a special inspection report was formed. Li Tianfeng carefully read this thick inspection report and signed it himself. This inspection report will be kept as important information. At least ten of them are kept.

The relevant information about the engine will generally be kept for ten years. If it is even fifteen or twenty years, the information will be kept for more than ten years.

After 150 hours of long-lasting test run, there were basically no problems with each part, which indicates excellent engine quality, very successful design, and basically no problems with manufacturing and assembly processes.

This good news spread throughout Tianfeng Technology Company in an instant. When everyone heard such good news, they talked about it with great interest. Especially some technicians were extremely happy.

"Mr. Liu, you are involved in the design of the turbo disc part. The design is very good. The engine has undergone a 150-hour long-lasting test, so there is no problem at all."

"Mr. Li, you are the same. You have participated in the design of the compressor part. The test run of the compressor part is excellent, which is amazing!"

“…”

The designers of the design institute were not only happy, but also a huge sense of accomplishment rose from the bottom of their hearts. Everyone participated in the design to a greater or lesser extent. Some senior engineers and even the main force of design were even happier.

Designers and craftsmen, everyone is very happy, and their hearts are full of a strong sense of accomplishment. The same is true for front-line workers. Every part of the engine is made by workers, and everyone has no less sense of accomplishment than designers and craftsmen.

"Old Zhao, I'm so happy that the engine was successfully tested for 150 hours!"

"Yes! The 150-hour long-lasting test drive is exciting and it is a complete success. The engine performs well and is good. I have to drink two taels after I get off work today."

"We are all made by the engine. I am so happy to see the parts we made as the engine and have passed such a test drive!"

"Yes, not only is it happy, but it is also very proud. Every day when I go home, my son pesters me about the aircraft engine. I feel very comfortable and proud!"

“…”

As Tianfeng Technology's employees succeeded in this 150-hour long-term test run, everyone seemed to have been given a wave of stimulants. Everyone's mental outlook was boosted, they were more motivated and more positive.

Songzhou Daily reported on the front page that the title "The 150-hour long-lasting test run of a certain type of machine in Tianfeng Technology Company" attracted a lot of attention.

"Tianfeng Technology is amazing, and it has actually been a successful 150-hour long-lasting test drive!"

"Yes, it's very amazing. This is the pride of our Songzhou!"

"Yes, it is our absolute pride in Songzhou. If you talk about such a thing, it is enough to be proud!"

“…”

With the report of the Songzhou Daily, the general public in Songzhou City had a heated discussion. After a meal, whenever they talked about this matter, everyone was dancing with joy, and the expressions on their faces were often very wonderful, and many citizens even took it as proud.

As an aviation industry enterprise, the employees of the e-factory are also in Songzhou. When they heard this news, they were happy and envious.

"Old Xu, Xiaotian, the former office, was so fast that this young man saw the opportunity. He changed jobs and joined Tianfeng Technology. Not only did his salary increase a lot, but he also participated in the research and development of such advanced engines. Tsk, I really envy him."

"Yes, there were many people who switched to Tianfeng Technology at the beginning. I regretted it because I hesitated!"

"I was also hesitant at the beginning and wanted to wait and see. Later, our factory and Tianfeng Technology Company reached an agreement to no longer recruit those who had switched jobs from our factory. Otherwise, I would like to change jobs to Tianfeng Technology immediately."

"I also want to change jobs to Tianfeng Technology. They are developing very fast and their treatment is good."

"Not only these, look at them. Such an advanced turboshaft engine has completed a 150-hour long test. How amazing is it. As an aviation worker, if I can participate in it, I will never regret it in my life!"

“…”

The employees of e Factory were envious and regretful when they heard such news. Of course, some were also happy for Li Tianfeng, especially some of Li Tianfeng’s colleagues and friends in e Factory. Everyone was very happy for a while when they heard such good news, and some even called Li Tianfeng to congratulate him.

Li Tianfeng has received many calls from e Factory in the past two days, including Liu Qingshan, Peng Xuehai, Cheng Gang and others, and even Zhu Maohua, Yang Xianfeng and others.

As Li Tianfeng's friend, Yang Xianfeng called after hearing that Tianfeng Technology successfully completed the 150-hour long test.

"Tianfeng, congratulations on completing the 150-hour long test successfully."

Li Tianfeng: "Mr. Yang, your information is so well-informed. I will know so quickly, thank you."

The two chatted on the phone, and Li Tianfeng happily accepted Yang Xianfeng's congratulations. After chatting for a few minutes, Yang Xianfeng said: "Tianfeng, are you free in the evening? We haven't had two drinks for a long time. Find a place tonight and have a good gathering."

Li Tianfeng thought in his mind that Yang Xianfeng might have something to come to him, so Li Tianfeng agreed readily: "Mr. Yang, we're free tonight, so let's have two drinks."

When Yang Xianfeng saw Li Tianfeng agreeing, he was very happy, "Okay, just go to the 'fishing port house', let's eat some wild fish and take a look at the river view."

Li Tianfeng knew that "Yugang Renjia" was a newly opened high-end restaurant with its specialty, which is wild fish. It has various methods, tastes delicious, and is close to the river. You can see the beautiful river view. The business is very good. Unexpectedly, Yang Xianfeng chose it there.

It can be seen that before making this call, Yang Xianfeng should have booked a private room, otherwise it would be impossible to say "Yugang Family" in one go.

Li Tianfeng thought to himself that something should be happening, otherwise it would be impossible to book a private room in the "Yugang Family" early.

The two chatted on the phone for a few minutes and agreed to have dinner together in the evening. After the two finished the phone, Li Tianfeng turned on one of his computers.

In Li Tianfeng's office, there are two computers, one connected to the internal network of Tianfeng Technology, which is physically disconnected from the external network, and the other computer is connected to the external Internet. This computer is physically disconnected from the internal network of Feng Technology, and the two computers are physically disconnected from each other. This is because of the need for confidentiality.

This computer connected to the external Internet is not Li Tianfeng's work computer, and there is no information inside. The main function of this computer is to go to the Internet site as soon as possible.

Turn on the computer and log in to the famous military forum in China. Li Tianfeng recently fell in love with this forum and registered an account. The reason why Li Tianfeng fell in love with this military forum is that there are many professionals in this forum and can often see posts about the engine of his Tianfeng Technology Company.

Seeing the post "Tianfeng Technology Company successfully completed a 150-hour long-term test run", Li Tianfeng smiled slightly, and saw that the poster was "Zhang Daxia". Li Tianfeng clicked in and saw the content inside, and Li Tianfeng felt a sense of joy.

In this forum, this engine from Tianfeng Technology Company is one of the hot topics that everyone is concerned about. "Zhang Daxia" often reveals that the latest development of this engine has been published. Gradually, this engine from Tianfeng Technology has a lot of fans.

The post "Tianfeng Technology Company successfully completed a 150-hour long-term test run" attracted a lot of people, and there were a lot of comments in it. Li Tianfeng happily followed one by one.
