God-level industrial master

Chapter 631 The first engine enters assembly
There was a moment of incomparable dullness in the meeting room.

After a long time, the U.S. general who presided over the meeting said solemnly: "Gentlemen, from the perspective of progress, the Huaxia military may have already purchased the imported spare parts of the previous drones. We are one step slower. For their subsequent import procurement of spare parts, including the import of some metal materials, we have to tighten our pockets..."

He said a lot in one breath, the meaning is obvious, to create obstacles for Jiuzhou UAV Company's follow-up UAV production, and hinder the mass production of this UAV.

Someone suggested: "General, these measures may not be enough. Jiuzhou UAV Company is a wholly-owned subsidiary of Jiuzhou Industrial Group. They have strong scientific research capabilities. We prevent them from overseas procurement of imported spare parts, just to give They just created some obstacles, and I worry that in the next few years, they will gradually be able to realize the localization of these imported parts."

This is a fundamentally unsolvable problem.

Jiuzhou Industrial Group's strong scientific research strength is there, and it can only be temporary to prevent overseas procurement of imported spare parts. In the end, Jiuzhou Industrial Group may realize localization.

This meeting went on for a long time.

In the end, they finally formed some resolutions, including some shady tricks.

Tang Fei didn't know for the time being that the U.S. military had grasped the situation of Jiuzhou UAV Company, and he didn't know some methods they would take in the future.

At this time, Tang Fei was in Jiuzhou Industrial Group.

Two days ago, I personally went to the drone manufacturing factory in Guancheng City. After looking around there, Tang Fei was very satisfied with the progress of the construction there, especially the large parts of the first drone body have been successfully shipped. Arrived at the manufacturing plant of Jiuzhou UAV Company.

As for the components manufactured by the subsidiaries of Jiuzhou Industrial Group, Tang Fei was very relieved, because there were detailed technical information provided by the system, and the manufacturing progressed smoothly. Some components had already been manufactured, and these components were shipped Arrive at Jiuzhou UAV Company, and temporarily store it in the newly built large warehouse there.

Sitting on his boss chair, Tang Fei thought to himself that the final assembly of the first drone would definitely start in a few months. I don't know what happened to the engine of the first drone.

UAVs need advanced turbofan engines, two for each aircraft, and these engines are manufactured in the 336 factory.

In the future, it will also be manufactured in the 336 factory, because the engine is not like a large part of the airframe, and the volume of an engine is much smaller, which is very convenient for transportation.

In addition, Factory 336 is the production and manufacturing base of small and medium-sized aero engines in China. They are considered the best small and medium-sized engine manufacturing factory in China. The engines for drones are produced and manufactured there. Tang Fei is very relieved.

Just don't know what happened to the engine production?

Tang Fei thought so in his heart, I will be free in a few days, I will go there to have a look. At that time, the first engine should have started to enter the final assembly.

In fact, the first engine began to enter the assembly process a few days ago, and the first thing to do was the assembly of various components.

In the engine assembly workshop of Factory 336, the first engine of the UAV has already started the assembly of components, such as the assembly of the fan rotor, the assembly of the compressor rotor, the assembly of the turbine, the assembly of the combustion chamber and so on.

In a few days, these parts will be assembled, and then the general assembly of the engine will start, and these assembled parts will be assembled into a complete engine.

The engine assembly site of Factory 336.

Yi Chunhua, chief engineer and deputy general manager, basically stayed at the assembly site for the past few days. He regarded the assembly of the first engine of the UAV as the top priority and dared not take it lightly.

This is the first engine for drones, and it is also the most advanced medium and small turbofan engine in the world. Thinking that such an engine will be born in the 336 factory, Yi Chunhua, who has been working on engines all his life, will inevitably feel a little bit small. excitement.

On an imported dynamic balancing machine, the dynamic balancing test of the compressor rotor is being done.

When the engine is working, the compressor rotor compresses the air step by step and sends the compressed air into the combustion chamber. The speed of the compressor rotor is very high, reaching a speed of more than 1 revolutions.

Such a high speed requires the mass distribution of the rotor to be very uniform. If the mass distribution is slightly unbalanced and the center of gravity has a small deviation, the rotor will generate a lot of vibration and noise when rotating at high speed, which will seriously affect the entire engine. overall performance, and even lifespan.

Yi Chunhua led several key technicians and stood beside him patiently, with a serious face.And the two master workers are even more meticulous, and they are dynamically balancing the compressor rotor.

After about ten minutes, the dynamic balance was finally completed, and one of the master craftsmen said pleasantly: "It's unbelievable, the mass distribution of the compressor rotor is very balanced, and the dynamic balance is very small. Just a little stuff."

Generally speaking, such high-speed rotating parts are designed with a place for removing materials. Generally, the center of gravity and mass distribution are changed by removing part of the material to achieve a balanced mass distribution and a fully qualified dynamic balance.

The same is true for the compressor rotor. There is a place for material removal. The master worker picked up a marker pen and made a mark on the position where the material will be removed, then picked up the electric grinding milling cutter and started grinding to remove part of the material.

Yi Chunhua had a look of joy on his face, he did not expect the dynamic balance effect of the first compressor rotor to be so good.

Let everyone feel more at ease, after removing a little material, put the rotor on the dynamic balancing machine to do the dynamic balancing test again, the result is very perfect, the dynamic balance of the compressor rotor is very small.

Yi Chunhua looked happy, and stayed at the assembly site for a long time, watching the assembly of the first drone engine components, as well as the supporting conditions of the spare parts for the upcoming engine assembly, etc.

After reading this, he left the assembly site excitedly, knocked on the door and entered the office of Yu Shaoguang, the head of Factory 336. As soon as he entered, Yi Chunhua said, "Mr. Yu, I'm here to report the situation to you. Our first drone The assembly of the engine is progressing very well and final assembly of the engine will start in a few days."

Hearing this, Yu Shaoguang also became happy, stood up and said loudly: "I am relieved, and I can also call Director Zhang and President Tang of Jiuzhou Industrial Group to report the situation."

They have not debriefed because they were a little worried that the first engine would encounter various problems during the assembly process.

In this regard, they have "extensive experience". For every engine manufactured by Factory 336, there were always various problems during the early trial production of the engine, which were simply continuous.

To their great surprise, the manufacturing process was carried out in strict accordance with the technical data provided by Jiuzhou Industrial Group, and the whole process was surprisingly smooth, with very few problems, even the assembly process of the engine.

Yi Chunhua agreed: "I also think that the report can be made to make Director Zhang and Mr. Tang happy. In addition, I have a hunch that as long as the engine assembly process is carried out in strict accordance with the process and technical data, I think it will be very good. The smoothness of the engine will not be the same as that of the engines we have tried before."

"En." Yu Shaoguang nodded, "I'll make these two calls."

He first called Zhang Ping in front of Yi Chunhua and reported the progress of the assembly of the first engine, and then dialed Tang Fei's cell phone.

.......
Jiuzhou Industrial Group.

In the past few days, Tang Fei has been thinking about the progress of the first engine, and even picked up the phone to call Yu Shaoguang to inquire.

But he picked up the phone and put it down again. Tang Fei guessed that there was probably a reason why Yu Shaoguang and the others didn't take the initiative to report the situation of the first engine to him.

Maybe they are worried that they will encounter many difficulties during the assembly process, maybe they will still call to report to themselves in a few days.

Today, Tang Fei received a call from Yu Shaoguang himself.

As soon as the phone call was made, Yu Shaoguang said in a happy tone: "Mr. Tang, I want to report to you the progress of the first engine."

Hearing such words, and feeling Yu Shaoguang's deep joy, Tang Fei's interest came, and he said immediately: "Mr. Yu, I have been waiting for your call for several days, please tell me about the first one." The progress of the engine has entered the assembly stage."

"Mr. Tang, I'm really sorry I haven't called you to report the situation." Yu Shaoguang first apologized, and then said: "Our first engine entered the component assembly stage last week. From the current point of view, The assembly of various components is progressing relatively smoothly, and we are scheduled to start the general assembly of the entire engine next Monday..."

After answering the call, Tang Fei was very happy!

The first engine of the UAV has entered the component assembly stage, and the general assembly of the entire engine can begin in a few days.Yu Shaoguang extended an invitation to Tang Fei, and Tang Fei readily agreed.

When the final assembly of this engine is completed, Tang Fei is going to take a look, especially to see its test run. Tang Fei is also looking forward to this engine.

Be sure to check it out then.

"Boom, boom, boom!"

Not long after Tang Fei answered the call, there was a knock on the door of the office. He thought it was Wang Hailong or Xu Guangming who came in, but Tang Fei was a little surprised that it was Liang Xiaofeng who came in.

It seems that he rushed over from Guancheng City in a hurry, and something must have happened.

Tang Fei was slightly taken aback when he saw Liang Xiaofeng, and noticed Liang Xiaofeng's expression, his heart sank slightly, and he asked quickly: "Old Liang, did something happen?"
