Start with the aviation industry

Chapter 208

"Old Liu, what's going on over there, so many people ran over there."

"I don't know, maybe some new notice was posted."

"Go and have a look, there's a new notice!"

"."

More and more people ran over to the bulletin board, not only those who had no work in their hands, but some workers who were working stopped the parts they were processing and walked over.

Zhu Liangcheng came earlier, took up a better position, and clearly saw the contents of the notice.

In just three to five minutes, there were many people standing behind Zhu Liangcheng. There were three floors inside and three floors outside.

Those who came a little later could only keep their feet on the periphery, stretch their necks, and try hard to see the content of the notice.

"What did the notice say?"

"Can the person in front read it for everyone?"

"."

Finally someone said loudly, "The notice said that everyone is asked to watch the news broadcast at seven o'clock tonight. The news report of our turboshaft engine will be broadcast."

"Really!"

"I'm so excited, our engine is on the news broadcast."

"Old Zhu, you were interviewed last time, maybe you can show your face in the news broadcast."

After reading the content of the notice, Zhu Liangcheng felt happy for a while, and also looked forward to it, whether he could appear in the evening news broadcast.

If he could be on TV, especially in the news broadcast, it would definitely be a matter of glory, so he became a little excited.

After finally getting off work in the afternoon, Zhu Liangcheng rode his bicycle to the house after washing his hands. As soon as he got home, he turned on the TV, although it was not yet 06:30.

This is a 21-inch color TV.

He can also be regarded as an old employee of Leihuo Technology Industrial Group, and his salary and benefits are usually relatively high, so he can afford to buy a color TV.

"Old Zhu, you usually don't watch TV, what happened today?"

His wife was puzzled, and felt that Zhu Liangcheng seemed a little abnormal today. He stayed in front of the TV after work, which was not like this before.

Zhu Liangcheng was in a good mood, and said loudly, "Honey, cook some good dishes, and take out my bottle of good wine, I want to have a good drink tonight."

"Old Zhu, what is the big happy event today?"

Zhu Liangcheng didn't hide anything, and said very happily, "Our factory is on the news broadcast, maybe I will show my face in the news broadcast."

"Really, then I'll go to cook, and you are allowed to drink an extra glass of wine today."

His wife wore an apron and went to the kitchen, and got busy for a while. When the news broadcast started, she cooked a few delicious dishes, which were very hearty.

After broadcasting major domestic events, at 7:18, the news report on the LH500 turboshaft engine finally began to be broadcast.

According to the news, this is a world-class turboshaft engine independently developed by my country with complete intellectual property rights.

Not only the basic introduction of the engine, but also several close-ups.

Then, Zhu Liangcheng was completely excited.

"Honey, look, that's me!"

Although it took less than five seconds to show his face, Zhu Liangcheng couldn't be more excited, and his wife was about the same.

In the big villa.

Lin Feng had just finished eating, and was sitting on the big sofa in the living room watching the news broadcast, beside Hu Xiaoxiao, who was peeling an apple.

After peeling the apple, he cut a small piece, "Brother Feng, how does this apple taste?"

Lin Feng opened his mouth, and Hu Xiaoxiao put the small piece of apple into his mouth.

"Well, it's crispy and sweet, and it's still full of water. Let's eat another piece."

Hu Xiaoxiao cut another piece and put it in Lin Feng's mouth.

"Brother Feng, why haven't there been reports about our engine in the news broadcast yet?"

Lin Feng looked at the time, "It should be soon."

After two or three minutes, Hu Xiaoxiao said pleasantly, "Wow, it's really a report about our engine, so excited."

Hu Xiaoxiao's pretty face turned red with excitement, Lin Feng smiled happily, and read the news seriously.

It lasted almost 2 minutes, which is not too short. What made Lin Feng more satisfied was not only the basic introduction of this engine, but also several close-up shots, as well as the interview shots of He Hua.

"Brother Feng, I'm so happy, our engine is actually on the news broadcast."

Lin Feng smiled and said jokingly, "Come on, give me a kiss and celebrate."

Hu Xiaoxiao said coquettishly, "You're going to bully me again."

Lin Feng laughed.

She said in her heart, Xiaoxiao seems to be getting more and more beautiful, she needs to have a figure and a face.

The skin is fair and delicate, the face is delicate and beautiful, and the figure is tall. The key is that there is flesh where there is flesh, and the place where it should be thin is definitely not fat.

She is simply a top-notch beauty!
This beauty, if placed in Douyin, who is in his twenties, will definitely be a big hit. No beauty or face-lifting is necessary. Even plain makeup can instantly kill those so-called beauty internet celebrities.

This should be at least a C. If you have a chance, you must check it out and see how it feels.

Which man is not good-looking, and Lin Feng is the same, but he doesn't look like a certain type, his eyes shine when he sees a beautiful woman.

"Brother Feng, where are you looking?" Hu Xiaoxiao quit, and gave Lin Feng a coquettish look.

Lin Feng smiled quickly and said, "I'm going to buy you a piece of clothing to see what size fits you better."

Hearing that she was buying clothes for herself, Hu Xiaoxiao said, "Really, then I'll buy you one too, and we'll go shopping together next time."

After watching the news broadcast, Hu Xiaoxiao got up and prepared to go back.

Lin Feng said, "It's already so late, I won't go back tonight."

Hu Xiaoxiao blushed slightly, "No, I'm afraid you will bully me, I'd better go back."

She usually seldom comes here at night, and when she does, it is during the day, and she never stays here. Girls in this era are relatively conservative, and Hu Xiaoxiao is no exception.

Lin Feng said, "I promise I will never bully you."

When I said this, I laughed in my heart, thinking of the story of "I just hang around outside for a while, and I promise not to go in".

Hu Xiaoxiao still said, "No, I'm still afraid that you will bully me. It's already 07:30, I have to go back."

She used to live in the collective dormitory of the Phoenix Factory, but now she has moved out and rented a two-bedroom apartment next to the Phoenix Factory. She still lives with Ma Xiaoli, but each of them lives in a bedroom and shares the living room and bathroom.

Although he was talking nonsense, Lin Feng didn't think that Hu Xiaoxiao could really stay, so he said, "Then I'll see you off."

It's not safe for a girl to ride a bicycle at night.

Without driving, Lin Feng also rolled out his own bicycle, and the two of them went down the mountain talking and laughing, each with a bicycle.

Going back to her rented house, she took out the key and opened the door, Hu Xiaoxiao pushed the door gently and entered.

Ma Xiaoli was slightly surprised, "Xiaoxiao, don't you live with the master?"

Hu Xiaoxiao blushed, "Little Ma, what are you talking nonsense about?"

Ma Xiaoli said, "Xiaoxiao, you're finished. If you don't cook the rice, be careful that the master will be snatched away by other girls."

Hu Xiaoxiao's face turned even redder, "Little Ma, if you talk nonsense again, I'll ignore you."

Ma Xiaoli shook her head lightly, thinking in her heart, if it were me, I would have tied him firmly for such a handsome, capable, and rich boyfriend.

No matter how you look at it, Xiaoxiao is a little dangerous.

The master is so good, if he is really snatched away by some girl, there will be no place to cry.

The LH1500 turboshaft engine was broadcast on the news broadcast, which became a hot topic not only in Leihuo Technology Industrial Group, but also in Phoenix Factory and other aviation industry enterprises.

Phoenix Factory, workshop 406.

In the smoking room, there are at least a dozen front-line workers smoking and resting here, and they are talking about this turboshaft engine from Leihuo Technology Industry Group.

"Did you watch the news broadcast last night?"

"I didn't see it, what's the matter?"

"I didn't read it either. I was working overtime in the workshop last night."

"Then you missed the opportunity, it's a pity."

"Old Zhang, what's the matter? Could it be that there was any major news on yesterday's news broadcast?"

"Hehe, you don't know yet, the turboshaft engine of Leihuo Technology Industrial Group was on the news broadcast last night."

what!
No way!
Quite a few people showed surprise, and looked at Lao Zhang, thinking that their ears had heard it wrong, or they simply thought it was a joke.

Seeing so many people looking at him, Lao Zhang smiled proudly, "It's absolutely true, not only was it on the news broadcast, but it was reported for at least 2 minutes."

"I also watched the news broadcast yesterday, and I can attest to that."

OMG!

The astonishment on everyone's faces became more obvious. Everyone knows what it means to be on the news broadcast.

"It's so awesome, it's actually on the news broadcast."

"I know this turboshaft engine. I have machined its parts."

"I also processed its parts. When the design was verified, I processed the first-stage turbine disk."

"."

The smoking room became lively, and everyone chatted about the turboshaft engine one by one with great interest, and some people showed pride on their faces because they had processed the parts of this engine.

Following the reports of the news broadcast, many units in the domestic aviation industry are talking about this turboshaft engine.

Not only some aero-engine factories, aircraft factories, or research institutes, but even some university teachers and students with majors related to the aviation industry are also talking about this matter.

Such as an aerospace university.

Several gray-haired old professors were chatting.

"Leihuo Technology and Industry Group has simply created a miracle, a world-class turboshaft engine."

"It took less than two years from the beginning of design and development to the verification and test run of the whole machine. If it weren't for the news report, I really wouldn't believe it."

"With the success of this turboshaft engine, the gap between us and Western countries in the field of turboshaft engines has been greatly narrowed at once."

"If you have a chance, you must go to Leihuo Technology Industrial Group to take a look at this turboshaft engine."

"."

In the past few days, this turboshaft engine has become a hot spot in the domestic aviation industry, and even some foreign media have sporadic reports.

Test workshop.

In the huge test drive control room, everyone was both excited and a little nervous.

The 300-hour long-term assessment test run has reached the most critical moment, and the countdown on the time display is very eye-catching.

The remaining time is 32 minutes and 17 seconds!
The test run is coming to an end, and there are still 32 minutes to end, but at this time, no matter whether it is the test run workers or the test drive technicians, they can't calm down at all, because this is the most critical moment.

As the technical director of the test car workshop, Xia Yang basically came to visit two or three times a day, and sometimes even stayed for an hour or two.

Of course he is here now, not only him, several other leaders of the test car workshop, several technical directors, etc., are all in the test car control room, and everyone is not looking at the engine working on the test car through the huge vacuum glass , Just take a look at the data on the instruments and meters.

Not long after, there was movement outside the door.

From Lin Feng down, all the senior leaders of Leihuo Technology Industrial Group, including Fang Anping and other experts, came here together.

"Hi boss."

"Mr. Lin, hello."

Everyone greeted Lin Feng proactively.

Lin Feng raised his hand and pressed it down, indicating that everyone does not need to get up. At this time, the test drive is the most important thing.

"How's the situation?"

Xia Yanghui reported, "Boss, so far, the test run is normal, and there are 21 minutes until the end of the test run."

Many people watched the countdown to the test run.

Lin Feng looked at the engine on the test bench, and looked at it for two or three minutes before looking back.

The engine has been working, and it is now at full rated power. The sound of its operation is transmitted through the vacuum glass and into everyone's ears.

Experienced people know that the sound is very normal.

This engine is also putting out strong power, with an output of 1526 kW.

The time passed by one minute and one minute.

The closer to the end of the test run, the quieter the test drive room became. Gradually, the 300-hour long test entered the countdown stage.

10-9-8
300 hours countdown to zero!
Without anyone's instructions, a loud report sounded.

"Fuel consumption is normal!"

"Engine torque normal!"

"."

In the sound of "normal", the engine that had been working for 300 hours gradually stopped. Whether it was the compressor rotor or the turbine rotor, they were only rotating by inertia.

After a while, it stopped turning completely.

A loud voice sounded, "The engine is running normally!"

Hearing this, Lin Feng was the first to applaud, and then there was warm applause and cheers in the test drive control room.

The 300-hour long-term assessment test run is over!
So far, its performance is excellent, and the data is also very normal.

But there is still the last hurdle. The engine must be transported back to the aircraft assembly workshop for disassembly and inspection. If there are no problems with all parts, it means that the 300-hour long test has passed successfully.

If there is a problem with some parts, it is necessary to analyze the cause and then make rectification. If it is due to the design, it may be more troublesome and may involve design changes.

The next day, the engine arrived at the assembly shop and began disassembly.

The whole disassembly process is relatively fast. In one morning, the external pipelines, lines, sensors, clamps, etc. of the engine are all disassembled, and the engine becomes a unit state.

In the afternoon, each unit was disassembled separately.

It can be seen that the workers' movements are much more proficient, and everyone has a clearer understanding of the structure of this engine.

Each unit body eventually becomes a part state.

Even at night, the huge assembly workshop is brightly lit. Not only Qin Jianguo and other leaders of the assembly workshop are here, but Fang Anping, an aero-engine expert, is also here.

Everyone held a magnifying glass and a flashlight, and carefully checked the condition of each part.

"Mr. Fang, look here, there is a little wear and tear."

Fang Anping looked at it seriously, and then said: "Within the normal range, there is no problem."

There is always a little bit of wear on the teeth and sealing ring, as long as it is within the normal range, it will be fine.

There is a little discoloration of the first stage turbine blades, as well as a little discoloration of the second stage and free turbine blades, but to a lesser extent.

This is also normal. With such a high working temperature, it is almost impossible for the turbine blades to keep working for 300 hours without discoloration.

It was busy until after eleven o'clock in the evening.

Everyone concluded that there is basically no problem with each part, at least from the appearance inspection and size measurement.

Starting tomorrow, some key and important parts will undergo various further inspections, such as fluorescent inspection of turbine blades and turbine disks, etc.

in the office.

Lin Feng was listening to Fang Anping's report.

After two or three days of busy work, all inspections were completed. During this period, Lin Feng also went to the assembly workshop to have a look.

"Boss, all inspections have been done. Our engine has no problems and passed the 300-hour long test."

Hearing this, Lin Feng felt relaxed all over.

I even thought in my heart that it is indeed a turboshaft engine designed by the system. It is really awesome. The verification test run was passed at one time, and the 300-hour long-term assessment test run was also passed smoothly.

Lin Feng said, "The 300-hour long test has been passed, and we should consider the finalization of the design."

Fang Anping said, "Boss, I will handle these things, and I will definitely handle them beautifully."

He is full of passion for his work.

The finalization of the design will be led and completed by the team led by Fang Anping, and then there will be small batch production of this turboshaft engine.

After Fang Anping reported and left, Lin Feng thought in his heart that the small batch production of the LH1500 turboshaft engine would cost a lot of money.

Even if the cost is 100 million per unit, ten units is 1000 million.

It is estimated that the manufacturing cost is more than 100 million, maybe 150 million, or even higher.

Even if the manufacturing cost is 150 million, the cost is relatively low in the world. It is all due to the system. When designing this engine, it not only considers the performance and manufacturing process, but also considers the manufacturing cost. .

Lin Feng was thinking about small batch production in the future when the phone ringing on his desk interrupted his thoughts.

The call was from Lin Qiong from Shanghai.

　Ask everyone for monthly ticket support! ! !
