Although it is the first time for these assembly workers to assemble this engine, the cooperation is quite tacit, there is no feeling of getting in the way, and the assembly is relatively smooth.

After assembling a component, when the dimensions and related technical requirements are to be measured, everyone will stop and measure the relevant assembly dimensions and technical requirements and record them one by one.

For example, after the intermediate casing is installed on the combustion chamber casing, the runout measurement of the end face and inner hole of the intermediary casing should be carried out, and after the measured value is measured, if the assembly requirements are not met, fine-tuning is also carried out.

"Lao Li, the beating is a little too big, a little bigger."

"Knock a little bit more over here, a little lighter, a little lighter, okay, meet the requirements."

“……”

These assembly workers, in the process of assembly, are not immersed in work, but constantly communicate and cooperate with each other.

Master Wang is obviously the squad leader of the assembly class, and when he saw that the assembly of the intermediary casing met the requirements, he immediately said: "Xiao Zhang, you are responsible for tightening the screws, Lao Liu, you are responsible for installing the bearings." ”

Xiao Zhang nodded, took the torque wrench that had adjusted the torque, and tightened the screws in place one by one according to the tightening order to meet the torque requirements.

In aero engine assembly, most of the screws have tightening torque requirements, and there are clear regulations in the process, which must be strictly implemented, and the screw tightening sequence also has strict requirements, not which screw you want to tighten.

For example, the intermediary casing is installed on the burning casing, positioned through three precision positioning holes, and the beating of the intermediary casing is checked, and then 22 evenly distributed screws and nuts are required to be tightened.

The nuts used in these screws are all new self-locking nuts developed and produced by Tianfeng Technology itself, and there is no need to bend the lock plate after the screw nut is tightened according to the requirements like other aero engines. Tighten the lock nut to prevent the nut from loosening and failing in the future.

"Boss, this kind of screw is really good, there is less cumbersome nut lock bending and locking process, and the assembly is much smoother."

Li Tianfeng nodded, this engine. Basically, such self-locking nuts are used, in addition, such advanced self-locking nuts, there is already a certain market in China, last year there were more than 20 million sales, as we gradually accept this self-locking nut, the market will gradually expand, this year's sales will definitely double, and even several times the growth.

Liu Wei was on the side. Appear very focused, holding a digital camera, and photograph every step of the assembly from all angles.

After the intermediate casing is installed, the relevant parts are installed, and then the centrifugal impeller and the cover on the centrifugal impeller are installed......

Li Tianfeng and others stayed in the assembly workshop for two or three hours and watched for a long time. Seeing that the assembly process was relatively smooth, Li Tianfeng returned to his office satisfied.

Right now. Li Tianfeng did not emphasize the schedule, but put the assembly quality first, and the final assembly of this first engine is estimated to take about five to seven days.

Li Tianfeng promised Zhang Haiping that Zhang Haiping would be notified to come over when the first verification machine was assembled, so Li Tianfeng picked up the phone. Call Zhang Haiping.

"Director Zhang, there is something I want to tell you."

Zhang Haiping's voice was very low, probably in a meeting, and he whispered: "Mr. Li, what's the matter?" ”

Li Tianfeng said: "Director Zhang." The final assembly of our first demonstrator has begun, and we expect to complete the assembly of the first verifier in about five to seven days. ”

"What, so fast!" Zhang Haiping's voice suddenly rose several degrees higher, and with obvious joy, it was completely different from the appearance of the whisper just now.

Zhang Haiping said loudly and excitedly: "Mr. Li, this is a great event, I will come over immediately, and I will buy a plane ticket tomorrow." ”

Li Tianfeng said enthusiastically: "Director Zhang, tell me the flight schedule when the time comes, and I will send a car to pick you up at the airport." ”

Zhang Haiping: "Mr. Li, no, I'll take a taxi as soon as I get off the plane, and you can assemble this engine with your heart." ”

Zhang Haiping is indeed attending a meeting, and now, the voice is so loud, many people have looked at it, fortunately, Zhang Haiping's level is there, and there is no need to worry about everyone's dissatisfaction, in addition, Zhang Haiping is happy, how can he care about this.

Next to Zhang Hai, a major general asked: "Lao Zhang, what's the matter, so excited, this is not like your Lao Zhang's usual style." ”

Zhang Haiping said happily: "Lao Hu, didn't I tell you about Tianfeng Technology Company last time, the engine of this company has begun to assemble the verification machine." ”

Hu Delong said: "Lao Zhang, is that a private enterprise in Songzhou?" Which turboshaft engine with a claimed output of 1800KW and a power-to-weight ratio of 9? ”

Zhang Haiping said excitedly: "It is this company, it is this engine, and now the first verification machine has been assembled, do you know?" It's already in the final assembly! ”

Seeing that Zhang Haiping was so excited, Hu Delong reminded: "Lao Zhang, I advise you not to place too much hope, Tianfeng Technology is a private enterprise in the end, in addition, such an output power, such a power-to-weight ratio, this is also too exaggerated, be careful of them bragging." ”

Zhang Haiping said: "No, Tianfeng Technology will definitely not, I believe they can succeed." ”

Hu Delong couldn't help but shake his head slightly, "Lao Zhang, I also kindly remind you that being careful, being cautious is only beneficial." ”

Next to him, the rest of the major generals and colonels were basically the same, and they all shook their heads slightly, and everyone thought in their hearts, Lao Zhang was a little too excited, and in the end, he was afraid that the bamboo basket would be empty, and he would be happy.

Zhang Haiping couldn't wait to fly to Songzhou immediately, and said to Hu Delong: "Old Hu, you preside over the meeting." After speaking, he hurriedly walked out of the conference room, obviously preparing to go to Songzhou.

After watching Zhang Haiping leave, another major general next to him said: "Lao Hu, this time Lao Zhang may really be a little too much, a private enterprise, I don't believe they can make such an advanced turboshaft engine." ”

A colonel next to him also chimed in: "Yes, if a private enterprise can develop such an advanced turbine engine, then our domestic large aero engine companies will not have to find a piece of tofu to crash to death." ”

Another major general wearing reading glasses also said: "I also really hope that we have such a turboshaft engine, with such an engine, the performance of our Wuzhi 10 can simply jump, and it will become one of the most advanced armed helicopters in the world, which can be compared with the Longbow Apache." ”

"Yes, with such a powerful turboshaft engine, what else do you need to talk about, our Wuzhi 10 can be upgraded immediately, increase armor, increase firepower, install more advanced radar, and become the most advanced armed helicopter in the world."

"That is, the performance of our Wuzhi Ten has jumped, and our army can stand up its own solid backbone, instead of relying on a few Wuzhi Nine to support the façade."

“……”

In the conference room, everyone sighed, but after some emotion, everyone was not optimistic about Tianfeng Technology and thought that it was impossible to develop such an advanced aero engine.

………

Zhang Haiping has too many things at hand, and this time he went to Tianfeng Technology, not as his own military, but as a private person.

After dealing with the things in his hands, he arrived at Tianfeng Technology three days later, two days later than he expected.

As soon as he got out of the airport, Zhang Haiping saw the people who greeted him, who came holding a sign at the exit of the airport.

Li Tianfeng was very polite, although Zhang Haiping said that he would just take a taxi to come over, but Li Tianfeng still arranged a business car and sent someone to greet him at the airport early.

Seeing the young man who picked him up, Zhang Haiping immediately said: "I am Zhang Haiping from the capital, go, get in the car, we will go to Tianfeng Technology Company immediately." ”

The young man saw that it was already more than twelve o'clock at noon, so he said politely: "Director Zhang, why don't you eat lunch before you go." ”

Zhang Haiping hurriedly waved his hand and said, "Don't eat, get in the car, and go to Tianfeng Technology immediately." ”

The young man was slightly stunned, he didn't think that Zhang Haiping was so anxious, but what Zhang Haiping said, the young man did what he did, and immediately took Zhang Haiping into the car, and without waiting for Zhang Haiping to urge again, he immediately stepped on the accelerator and galloped away towards Tianfeng Technology.

……

Li Tianfeng's office.

Seeing Zhang Haiping, Li Tianfeng said enthusiastically: "Director Zhang, I heard that you didn't eat at lunch, I prepared some food in the reception room next door, let's eat a little and then go to the assembly workshop." ”

Zhang Haiping said: "No, no, go to the assembly workshop first, I don't see the assembly situation with my own eyes, where can I eat, when I am in the capital, I can't wait to come over earlier, but I am really entangled in official business." ”

Li Tianfeng didn't insist, it was already two o'clock in the afternoon, and the workers had already gone to work in the afternoon, so Li Tianfeng got up and said enthusiastically: "Director Zhang, let's go." ”

Final assembly workshop.

Li Tianfeng took Zhang Haiping and went straight to the assembly area, far away, Zhang Haiping saw the engine that was being assembled, and couldn't help but speed up the pace, originally, Zhang Haiping and Li Tianfeng were walking side by side, and now, it has become Zhang Haiping in front, and Li Tianfeng is a few meters behind.

The two of them walked quickly to the side of the engine, and at this time, the engine had already come to a 180-degree flip, butt up, and the assembly of the turbine part had begun.

Zhang Haiping stepped forward, excited, happy, and gently touched the engine that had been half assembled, as if he was touching a piece of art.

While stroking, he was excited and muttered happily, "Great, great, amazing, amazing!!

……………

Today's three watches, the first one is !!

The first engine has gone through a lot of hardships and finally has to complete the final assembly, brothers who have a monthly pass, support it, brothers who don't have a monthly pass, recommended tickets can also be ah. (To be continued......)
