There was a dullness in the room.

After a long time, the US general who presided over the meeting said solemnly: "Gentlemen, from the perspective of the process, the Huaxia military may have purchased the imported spare parts of several UAVs in the early stage, and we are one step slower, for their follow-up import and procurement of spare parts, including the import of some metal materials, we must tighten our pockets......"

He said a lot in one breath, and the meaning was obvious, giving Jiuzhou UAV Company follow-up UAV production and manufacturing obstacles and hindering the mass production of this UAV.

Someone suggested: "General, maybe these measures are not enough, Jiuzhou UAV Company is a wholly-owned subsidiary of Jiuzhou Industrial Group, they have strong scientific research strength, we prevent them from importing spare parts overseas procurement, just to create some obstacles for them, I am worried that in a few years, they will gradually be able to realize the localization of these imported spare parts." ”

This is a largely unsolvable problem.

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

The meeting went on for a long time.

Eventually, they finally came up with some resolutions, including some shady small means.

Tang Fei did not know for the time being that the US military had mastered these situations of the Jiuzhou UAV Company, nor did he know some of the means they would take in the future.

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

Two days ago, I personally went to the UAV manufacturing plant in Guancheng, and after a look there, Tang Fei was very satisfied with the progress of the construction there, especially the large parts of the first UAV have been successfully transported to the production and manufacturing plant of Jiuzhou UAV Company.

As for the parts produced and manufactured by the subsidiaries of Jiuzhou Industrial Group, Tang Fei was relieved, because there was detailed technical information provided by the system, the manufacturing progress was very smooth, and some parts and components had been manufactured, and these parts were also shipped to Jiuzhou UAV Company and temporarily stored in the newly built warehouse.

Tang Fei sat on his boss's chair and thought to himself, he would definitely be able to start the final assembly of the first drone in a few months, and he didn't know what happened to the engine of the first drone.

The drones are needed with advanced turbofan engines, two for each aircraft, which are manufactured at Plant 336.

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

In addition, the 336 factory is the production and manufacturing base of small and medium-sized aero engines in China, and they are the best small and medium-sized engine manufacturing plants in China.

I just don't know what happened to the production and manufacturing of the engine?

Tang Fei thought in his heart, when I have time in a few days, I will go there to take a look, at that time, the first engine should have begun to enter the final assembly.

In fact, the first engine began to be assembled a few days ago, starting with the assembly of the individual components.

In the engine assembly workshop of Plant 336, the assembly of components for the first engine of the UAV has begun, 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, the components will be assembled, and then the final assembly of the engine will begin, and the assembled parts will be assembled into a complete engine.

Engine assembly site at Plant 336.

Yi Chunhua, chief engineer and deputy general manager, has basically stayed at the assembly site these days, and the first engine of the drone has entered the assembly, which he regards as the top priority and does not dare to take it lightly.

This is the first engine of the UAV, and it is also the most advanced medium and small turbofan engine in the world.

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

When the engine is working, the compressor rotor compresses the air step by step, and the compressed air is sent into the combustion chamber, and the speed of the compressor rotor is very high, reaching a speed of more than 10,000 revolutions.

If the mass distribution is slightly unbalanced and the center of gravity has a small deviation, the rotor will produce great vibration and noise when rotating at high speed, which will seriously affect the overall performance and even life of the whole engine.

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

After about ten minutes, the dynamic balance was finally completed, and one of the masters said in surprise: "It's unbelievable, the mass distribution of the compressor rotor is very balanced, and the dynamic balance is very small, as long as you gently remove a little material on the rotor." ”

Generally speaking, this kind of high-speed rotating parts are designed for the place of removing materials, and generally by removing part of the material to change the center of gravity and mass distribution method, so as to achieve the purpose of mass distribution equilibrium and dynamic balance is fully qualified.

The same is true for the compressor rotor, there is a place for removing the material, the worker master picked up the marker, made a mark at the position where the material will be removed, and then picked up the electric grinding cutter and began to grind and remove part of the material.

Yi Chunhua's face already showed a look of joy, and he didn't expect the dynamic balance effect of the rotor of the first compressor to be so good.

Let everyone be more assured, after removing a little material, then put the rotor on the dynamic balancing machine to do the dynamic balance 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, looking at the assembly of the components of the first UAV engine, as well as the matching of the spare parts that are about to be assembled by the engine.

After reading these, he rushed out of the assembly site, knocked on the door and entered the office of Yu Shaoguang, the leader of the 336 factory, and said as soon as he came in, Yi Chunhua said: "Mr. Yu, I will report to you, the assembly of our first UAV engine is going very smoothly, and the final assembly of the engine will start in a few days." ”

Hearing this, Yu Shaoguang also became happy, stood up and said loudly: "Then I can rest assured, I can also call Director Zhang and Mr. Tang of Jiuzhou Industrial Group to report the situation." ”

They didn't debrief because they were a little worried that the first engine would run into problems during the assembly process.

In this regard, they have "a lot of experience". Every engine produced and manufactured by the 336 factory before will always have various problems during the early trial production of the engine, and it is simply one after another.

What surprised them was that the production and manufacturing were carried out in strict accordance with the technical information 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 I can make a report, so that Director Zhang and Mr. Tang are happy, and I have a hunch that as long as the assembly process of the engine is carried out in strict accordance with the process and technical data, I think it will definitely be very smooth, and it will not be like the engines we tried before." ”

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

He first made a phone call to Zhang Ping in front of Yi Chunhua to report the assembly progress of the first engine, and then dialed Tang Fei's mobile 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 for a while to call Yu Shaoguang to inquire.

But picking up the phone and putting it down again, Tang Fei guessed that Yu Shaoguang did not take the initiative to report the situation of the first engine to him, and it was estimated that there was a reason.

Maybe they're worried about the difficulties they will encounter during the assembly process, or maybe they'll call back to them in a few days.

Today, Tang Fei received a call from Yu Shaoguang in person.

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

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

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

After answering this call, Tang Fei felt very happy!

The first engine of the drone has already entered the stage of assembling components, and in a few days the final assembly of the entire engine will begin. Yu Shaoguang sent an invitation to Tang Fei, and Tang Fei agreed.

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

Be sure to stop by and have a look.

"Knock, knock, knock!"

Not long after Tang Fei answered the call, there was a knock on the door outside the office door, originally thought that the knock on the door should be Wang Hailong or Xu Guangming, which made Tang Fei feel a little surprised that it was Liang Xiaofeng who came in.

It seems that he rushed over from Dongguan City in a hurry, something should have happened.

Tang Fei saw Liang Xiaofeng froze slightly, noticed Liang Xiaofeng's expression, his heart sank slightly, and hurriedly asked, "Old Liang, is something wrong?"

…….

Today's third watch, the third watch is over, thank you for your support, good night!
