For the bearing, Li Tianfeng is very experienced, because the bearing is in a decomposed state, Li Tianfeng put away and picked up a ball of the main bearing, looked at it carefully, and also held a small flashlight, shine a light on the ball, with the strong light, so as to see more clearly.

After looking at it, Li Tianfeng nodded, this ball is not abnormal in the slightest, the surface is very bright, not even a trace of scratches, it looks very comfortable.

After looking at a lot of balls one after another, and then looking at the inner and outer rings of this bearing, Li Tianfeng looked very carefully and did not find any abnormality.

Looking at a number of bearings in a row, Li Tianfeng nodded slightly, although the quality of domestic bearings is slightly worse than that of imported ones, but they have come in a lot of considerations when designing, and they can also make up for this very much.

After looking at several important bearings, Li Tianfeng looked at the turbine outer ring, the turbine outer ring is sealed with metal honeycomb, when the engine is working, the turbine blade tip and the turbine outer ring maintain only ten filaments of clearance, of course, this is a theoretical design, when actually working, this gap may be small, or large.

If the gap is small, the leaf tip may rub against the honeycomb, and there will be a certain amount of wear on the peak nest, and slight wear is allowed, but strict wear is absolutely not allowed.

The outer ring of the free turbine, plus the outer ring of the two-stage gas turbine, a total of three levels, 12 pieces of the outer ring of each stage of the turbine, Li Tianfeng picked up one piece, and looked at it carefully, this piece of the outer ring of the turbine has a good peak socket and no wear and tear.

After looking at several pieces in a row, there was no wear, Li Tianfeng nodded slightly, the design of this engine is still good, and the three-stage turbine outer ring, a total of thirty-six pieces, was carefully looked at, and most of them were not worn. Only three of the pieces showed very slight wear and tear, which was too normal to be normal.

After looking at the honeycomb of the outer ring of the turbine, Li Tianfeng looked at the grate teeth on the turbine disk, and the grate teeth in this circle are also used to seal and allow a certain amount of wear.

Again, because it's well designed. After reasonable and sufficient calculations during the design, the grate teeth on the turbine disc are basically not worn, or very slightly worn, and completely within the normal range.

After reading the grate, Li Tianfeng looked at a lot of important and key parts, without exception, there were basically no problems, even if there was a little problem, it was completely within the normal range.

Three days later. All parts were inspected, forming a special inspection report, this thick inspection report, Li Tianfeng personally carefully looked at it, and also signed it personally, this inspection report, will be kept as important information. Save at least ten or more.

The relevant information of the engine is generally kept for ten years. Even if there are fifteen or twenty years, this information will be kept for more than ten years.

After 150 hours of long-lasting test runs, the parts were basically free of problems, which indicates that the engine is of excellent quality, the design is very successful, and the manufacturing process is very successful. The assembly process is also basically no problem.

This good news spread throughout Tianfeng Technology Company in an instant, and when they heard such good news, everyone talked about it and talked about it. In particular, some technicians are very happy.

"Liu Gong, you participated in the design of the turbo disc part, the design is very good, the engine has undergone 150 hours of long-term test test, there is no problem at all."

"Li Gong, you are the same, you participated in the design of the compressor part, and the compressor part test table is excellent, amazing!"

“……”

The designers of the design institute are not only happy in their hearts, but also a huge sense of accomplishment rises from the bottom of their hearts, everyone more or less participates in the design, and some senior engineers are even the main force of the design, everyone is even more happy.

Designers, technicians, everyone is very happy, the heart is full of a strong sense of achievement, the front-line workers are the same, every part of the engine, is made by the workers, everyone's sense of accomplishment in the heart is not less than the designer, the process personnel.

"Lao Zhao, the engine has been successfully tested for 150 hours, I am really happy!"

"Yes! 150 hours of sustained test run, think about it is exciting, and it is a complete success, the engine table xiàn is excellent, good, today after work home to drink two taels. ”

"The parts of the engine are all made by us, and I am so happy to see the parts I made into the engine and go through such a test run!"

"Yes, not only happy in my heart, but also very proud, every day when I go home, my son pesters me to talk about aero engines, I am very comfortable in my heart, very proud!"

“……”

With the success of this 150-hour long-lasting test run, everyone seems to have been stimulated, and everyone's spirit is lifted, more motivated and more positive.

"Songzhou Daily" on the front page, a large report on the test, "Tianfeng Technology Co., Ltd. 1 1 150 hours of sustained test run of a certain machine was a complete success", such a headline, attracted a lot of attention.

"Tianfeng Technology is amazing, and the 150-hour long-lasting test was a complete success!"

"Yes, it's amazing, it's the pride of our Songzhou!"

"Yes, it is the absolute pride of our Songzhou, such a thing, saying it, is enough to raise your eyebrows!"

“……”

With the report of "Songzhou Daily", the majority of citizens in Songzhou City have a heated discussion, after the tea meal, in the streets and alleys, whenever they talk about this matter, everyone is a burst of eyebrows and color dance, the expression on the face is often very exciting, and even many citizens are proud of it.

As an aviation industry enterprise, and also in Songzhou, the majority of employees of E factory, hearing such news, in addition to being happy, everyone is deeply envious.

"Lao Xu, Xiao Tian in our office, how fast this young man saw the opportunity at that time, he jumped ship to join Tianfeng Technology, not only did his salary rise a lot, but also participated in the research and development of such an advanced engine, tsk, I really envy him."

"Yes, there were a lot of people who jumped to Tianfeng Technology in our factory at the beginning, and I regretted it because I hesitated!"

"I also hesitated at the beginning, I wanted to wait and see, but later our factory and Tianfeng Technology Company reached an agreement to no longer recruit people who jumped from our factory, otherwise, I want to jump to Tianfeng Technology immediately."

"I also want to change jobs to Tianfeng Technology, people are developing very quickly, and the treatment is good."

"Not only these, look at others, such an advanced turboshaft engine has completed a 150-hour long test, how amazing, as an aviation person, if I can participate in it, I will have no regrets in this life!"

“……”

The majority of employees of Factory E, hearing such news, have envy, regret, of course, some are happy for Li Tianfeng, especially some of Li Tianfeng's former colleagues and friends in Factory E, everyone heard such good news, very happy for a while, and even some people called Li Tianfeng to congratulate.

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

As a friend of Li Tianfeng, when he heard that Tianfeng Technology had completed the 150-hour long test, Yang Xianfeng's phone called.

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

Li Tianfeng: "Mr. Yang, your news is really well-informed, I knew it so quickly, thank you." ”

The two chatted on the phone, Li Tianfeng was even more happy to accept Yang Xianfeng's congratulations, and after chatting for a few minutes, Yang Xianfeng said: "Tianfeng, are you free at night, we haven't had two drinks for a long time, find a place tonight and get together." ”

Li Tianfeng estimated in his heart that Yang Xianfeng might have something to do when he got together with himself, so Li Tianfeng readily agreed: "Mr. Yang, I happen to be free tonight, then let's have a good drink." ”

Yang Xianfeng was very happy when he saw Li Tianfeng agree, "That's okay, it's at the 'fishing port', let's eat a little wild fish and take a look at the river view." ”

Li Tianfeng knows that the 'Yugang family' is a high-end restaurant that has just opened, featuring wild fish, with various practices, delicious taste, and near the river, you can see the beautiful river view, the business is very good, I didn't expect that Yang Xianfeng chose 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 people' in one bite.

Li Tianfeng thought in his heart, there should be something, 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 said that they would have dinner together in the evening, and after the two ended the phone, Li Tianfeng turned on one of his computers.

In Li Tianfeng's office, there are two computers, one is connected to the intranet of Tianfeng Technology, which is physically disconnected from the external network, and the other computer is connected to the external Internet.

This computer connected to the external Internet is not Li Tianfeng's work computer, and there is no information in it, and the main function of this computer is to get on the Internet website.

Turn on the computer,Log in to the famous military forum in China,Li Tianfeng recently liked this forum,And also registered an account,The reason why Li Tianfeng likes this military forum,There are many professionals in this forum,And you can often see posts about the engine of your Tianfeng Technology Company。

Seeing the post of "Tianfeng Technology Company completed 150 hours of long-lasting test run", Li Tianfeng smiled slightly, and saw that the poster was "Zhang Daxia", Li Tianfeng clicked in, and when he saw the content inside, Li Tianfeng was happy in his heart.

In this forum, the engine of Tianfeng Technology Company is one of the hot spots of everyone's attention, and "Zhang Daxia" often breaks the news and sends the latest development of this engine, and gradually, this engine of Tianfeng Technology has a lot of fans.

As soon as the post of "Tianfeng Technology Company completed 150 hours of long-lasting test run" was published, it attracted a lot of people, and there were a lot of posts in it, and Li Tianfeng happily read them one by one.
