Now, the engine has completed the assembly of the combustion chamber part and the compressor part, and the engine assembly bench has been turned 180 degrees, and the combustion chamber installation surface where the turbine is installed is facing up, and the installation of the turbine part has begun.

The first is the installation of the free turbine, before the installation of the assembly workers, check the runout of the mounting surface, the coaxial of the mounting hole, etc., after passing the inspection, record the number of these inspections one by one, and then carry out the installation of the free turbine.

The free turbine does not output power to the outside world, and there is only a first-stage turbine, when the free turbine works, it mainly drives the centrifugal impeller, the axial flow impeller rotates at high speed, and drives some accessories, the rotation of gears and so on.

The installation of the free turbine is very critical, these workers, cooperate with each other, very seriously, after the free turbine is installed, check the runout and coaxiality to meet the requirements, and then start the next step of installation.

The installation of the turbine casing is also very critical, the turbine casing and the combustion chamber casing are connected, the two are positioned by three precision positioning pins, after the installation and positioning, a series of dimensions are checked, and then the screws are tightened as required.

Zhang Haiping has been looking very carefully, and even picked up a screw and looked at it carefully for a long time, and then said: "Mr. Li, this screw is an ordinary aero engine screw, but I have never seen a nut matching it." ”

Li Tianfeng introduced his own self-locking nut, Zhang Haiping's eyes lit up, and he praised: "Mr. Li, you are really amazing, such an ingenious self-locking nut can also be designed." ”

Li Tianfeng said: "In our engine, more than eighty percent of the nuts use such self-locking nuts, which not only saves time and effort in assembly, but also has a very high reliability of the nuts, and will never cause loose nuts and failures in the future use process." ”

The two chatted from time to time. From time to time, I took a look at the assembly of this engine, and the time passed very quickly, and an afternoon passed like this.

An afternoon of assembly, the turbine section has been completed, a one-stage free turbine, a two-stage gas turbine. Including the turbine casing, all assembled.

At this point, the compressor, combustion chamber, turbine several main components are all installed, and then, only the installation of accessories, such as transmission gears, control parts, as well as oil circuits, circuits. It's going to take about two or three days.

Looking at the time, it was already time to get off work in the afternoon, Li Tianfeng said: "Director Zhang, let's go, now we can go to dinner, let's have a good drink tonight." ”

Zhang Haiping said with a smile: "Time flies so fast, now I feel a little hungry, go." We're going to have two drinks tonight. ”

………

In the next two or three days, Zhang Haiping had only one thing. I have been soaking in the assembly workshop, watching the assembly process throughout the whole process, and I am very interested, and I am not tired of it, even if I stay for a whole day, I don't feel tired at all.

On the contrary, Zhang Haiping is in high spirits every day. He was very familiar with several assembly workers, and even chatted with the assembly workers about some problems in the assembly process.

Li Tianfeng didn't have so much energy, so he could only go to the assembly workshop once a day in the morning and once in the afternoon. Every time I stayed for more than half an hour, I chatted with Zhang Haiping, communicated, and by the way, I also took a look at the assembly of the engine I cared about.

Zhang Haiping is also very understanding, knowing that Li Tianfeng has a lot of things, and it is impossible to accompany him all day long.

Li Tianfeng does have a lot of things, not to mention the assembly of the first verification machine, that is, the construction of the test bench, and many things need to be checked by Li Tianfeng one by one.

Even if it is just a ground test platform, it is not the construction of a high-altitude platform with higher technical content, longer cycle and greater difficulty, but there are also many things, especially some more complex technical problems, Li Tianfeng can't pay attention to it.

Fortunately, Sun Xiaoping's level is good, he has solved a lot of problems, and he has acted as his assistant excellently, otherwise, the construction of the test bench is far from being so smooth. Although the construction of the test bench is not as advanced as the first demonstration machine, it is also nearing completion, and the official completion will be about half a month later.

Zhang Haiping has been watching this engine to complete the assembly in an all-round way, of course, the moment the engine finally completed the assembly, Li Tianfeng was also at the scene in person, personally witnessing the completion of the assembly of this engine.

Even, the last symbolic screw of the engine was screwed by Li Tianfeng himself, as the real boss of Tianfeng Technology, this screw can really only be completed by Li Tianfeng himself.

At the moment of completion, there was a thunderous, warm, and long-lasting applause all around, and beside it, surrounded by middle and senior personnel of Tianfeng Technology Company, including the director and deputy director of each workshop, today, in the development history of Tianfeng Technology Company, is a day of great historical significance.

Zhang Haiping is the same, warm applause, joy and excitement, Zhang Haiping is also a witness of the first engine today, in the history of the development of Tianfeng Technology Company, will definitely leave a strong stroke.

A big red flower that had been prepared a long time ago was brought up on a delicate plate, and Li Tianfeng warmly invited: "Director Zhang, let's put this big red flower on our first engine together." ”

Zhang Haiping nodded excitedly, so Li Tianfeng and Zhang Haiping tied this red silk saffron to this engine.

All around, there was another round of warm applause.

Looking at the engine with a little excitement, Zhang Haiping said: "Mr. Li, can I take a photo?" ”

Li Tianfeng was in the right mood, so he nodded.

Zhang Haiping took out his mobile phone and took several photos of the turboshaft engine, from multiple angles, including front and side photos.

"Bang, bang, bang......"

At this time, a deafening salute sounded outside the assembly workshop, and a bucket of fireworks that had been prepared for a long time was being fired.

The whole Tianfeng Technology people, all heard the loud sound of the fireworks, everyone looked in the direction of the assembly workshop, and even, some employees ran out, in the open space outside the plant, watching this scene, everyone was happy.

"Our first aero engine was assembled !! smoothly"

"Really!"

"Great, so excited!"

"Yes, after working hard for so long, I finally have a result, and it is still such a gratifying result, I am so happy!"

The majority of employees of Tianfeng Technology, everyone is happy, their faces are full of pride and pride, their first aero engine was successfully assembled, which is enough to make everyone extremely proud and proud.

Tianfeng Technology Co., Ltd. is located in Songzhou High-tech Development Zone, there are many enterprises and factories around, Tianfeng Technology is such a big movement, many employees of other enterprises and factories have noticed, at the beginning, everyone did not know what was going on.

"What day is today, why did Tianfeng Technology Company set off so many flowers?"

"I don't know, is it the first anniversary of Tianfeng Technology Company?"

"Come on, it's only been one year since Tianfeng Technology Company was established, and it seems to be two or three years."

"Then it's strange, what kind of festive thing is to set off so many fireworks to celebrate."

The employees of the surrounding factories and enterprises, at the beginning, heard such a sound of ceremonies, and did not know what was going on, but there was no impermeable wall in the world, and gradually, it spread in a small area, and some employees of some surrounding factories and enterprises still knew what was going on.

"I heard that Tianfeng Technology has successfully developed an aero engine, and a large number of fireworks were set off in the morning to celebrate."

"What? Aero engines, that's tall stuff, it's so exciting, no, I'm a little excited and I can't stand it. ”

"Yes, aero engine, it's enviable when you think about it, if I am an employee of Tianfeng Technology, I will raise my head a few points when I go out."

“……”

For several days in a row, some employees of some surrounding factories and enterprises are bursts of heated discussions, speaking of this matter, everyone is either frowning or secretly envious, and even some people are happy in their hearts, as if their company has built an aero engine.

……

At night.

Li Tianfeng politely set up a celebration banquet at the State Guest Hotel, and dozens of tables were held, which were attended by the supervisors and above of Tianfeng Technology, as well as all the designers.

Li Tianfeng is in a very good mood, very happy, everyone in Tianfeng Technology is the same, today belongs to everyone, the first aero engine assembly is completed, which is enough to make everyone happy for a long time.

Zhang Haiping was also very happy, witnessing the completion of the most advanced turboshaft engine in Tianfeng Technology, during the banquet, Zhang Haiping held a wine glass, and said happily: "Mr. Li, I am so happy today, even if I am not so happy during the New Year, Mr. Li, congratulations!" ”

Li Tianfeng also raised his wine glass, happily clinked glasses with Zhang Haiping, and drank all the wine in the cup.

Zhang Haiping said: "Mr. Li, when your test bench is completed and this engine enters the verification test stage, I want to take a look again." ”

Li Tianfeng warmly invited: "Director Zhang, you are warmly welcome to come, and I will inform you when the verification and test run is ready." ”

"Okay, that's it."

Tonight, the celebration banquet was very warm, Li Tianfeng was drunk, Zhang Haiping was drunk, and many people from Tianfeng Technology were drunk.

Zhang Haiping was supposed to take a flight back to the capital at nine o'clock in the morning the next day, but because he was so happy and in such a good mood, he drank a little too much, and he slept until the next morning before getting up, delaying the flight, and returning to the capital by high-speed train from Songzhou at noon.

Li Tianfeng is basically the same, sleeping until noon the next day, many people from Tianfeng Technology who participated in the banquet were drunk because they were too happy, and many people were late for work the next day.

Of course, Li Tianfeng didn't count the lateness of the big family this time, and his tardiness this time was completely understandable.

Today's three watches, the second one will be sent!! (To be continued......)
