Start with the aviation industry

Chapter 206 Shocked the entire aviation industry

Workshop 406, technology room.

In the large office, most of the craft technicians are busy with their own work, or writing process change orders, or preparing temporary process regulations, but a few young craft technicians are talking.

"Leihuo Technology Industry Group is awesome, their verification machine has successfully passed the first verification test run."

"I've heard that too. I can't believe it. I passed it in one go."

"You guys belong to the evening news. This turboshaft engine has been disassembled and inspected. I heard that no problems have been found."

"."

Their discussion attracted the attention of some other craft technicians, so more and more people joined the heated discussion.

The originally relatively quiet crafts and technology room gradually became lively. At least half of the people were chatting about this matter with great interest. Although the others did not join the ranks of the hot chat, they were also listening with their ears pricked up.

Many craft technicians are simply elated.

Especially for those who have a good relationship with Lin Feng, they have an expression of admiration on their faces, and they almost regard Lin Feng as an idol.

"Brother Lin is amazing. I didn't see it at the beginning. I should have hugged Brother Lin's thigh tightly if I knew it."

"Amazing, a world-class turboshaft engine."

"The key is that it took less than two years from the beginning of the design to the test run of the verification machine, which is simply a miracle."

"."

When everyone was chatting lively, Yan Bing, the workshop director, walked in, and suddenly, the lively big office became much quieter.

Yan Bing was not dissatisfied at all, but smiled all over his face, "It's okay, you continue to chat, except today."

Seeing this, a bold craftsman said loudly, "Director Yan, you should know more about the situation than us. Tell us about the turboshaft engine of Leihuo Technology Industrial Group."

With the beginning of this craftsman, other people started to ask questions in a hurry, you have a question, I have a question.

Yan Bing said frankly, "You really asked the right person. I do know some specific information, so I will tell you about it."

He briefly explained the situation of this turboshaft engine.

Everyone pricked up their ears and listened carefully.

After listening, the office became lively again.

"My God, it's all true."

"It's so awesome, there is no problem with the engine disassembly inspection."

"As expected of Leihuo Technology Industrial Group!"

"."

This kind of scene didn't just happen in workshop 406. Similar situations also occurred in other workshops of Phoenix Factory. Many technicians and managers were talking about this matter, even some workers in the manufacturing site.

Such as precision manufacturing workshop production and manufacturing site.

A base of a ten-meter-long CNC broaching machine is being cast, and turbine blades for turboshaft eight and turboprop six are being cast not far away.

Several workers had no work in their hands for the time being, and they were talking about the test run of Leihuo Technology Industrial Group, and gradually they talked about the turbine blades of the LH1500 turboshaft engine.

"The turboshaft engine of Leihuo Technology Industry Group passed the verification test in one go, which really surprised everyone."

"Yeah, one-time pass, this kind of situation is very rare."

"Old Liu, I heard that you took everyone to cast the turbine blades of this turboshaft engine. It should feel very cool now."

"To tell you the truth, I heard that this turboshaft engine passed the test run for the first time. I was so happy that I almost couldn't sleep last night. Its turbine blades were indeed cast by me with everyone."

"Thinking about it now, the whole set of precision casting process regulations is very good, and the operability is very strong. The design of those turbine blades is also very special. It is also the first time we have cast hollow turbine blades."

"."

Many parts of this turboshaft engine were manufactured by Phoenix Factory, including turbine blades, some forging blanks and so on.

Leihuo Technology Industry Group.

Fang Anping called everyone to a meeting, except for the chief and deputy directors of the assembly workshop, test workshop and other workshops, most of them were from Leihuo Aeroengine Design Institute.

Almost all design experts, design backbones, directors of various design offices, etc., dozens of people are having a meeting.

The content of the meeting is related to this verification machine.

Summarize the situation of this verification test run, summarize the situation of engine disassembly and inspection, and review this verification test run.

All kinds of data have been sorted out and displayed in front of everyone through slides. Fang Anping is personally introducing it to everyone.

The verification test run is perfect, basically no problems.

There were no major problems with the disassembly inspection of the engine, only three category C problems.

Verification test run, including engine disassembly and inspection after test run, is generally divided into three categories: A, B, and C.

Category A is a particularly serious problem, generally involving major design changes of aero-engines, or even the redesign of some important and key parts, etc.

Category B is a general major issue and may involve some design changes and refinements.

Category C is a general problem, which does not involve design changes and improvements, and can be solved by general rectification.

This time, there were only three category C problems. After a simple analysis, the solutions and plans were quickly come up with, and the rectifications were in place within two or three days.

After the meeting lasted for more than an hour, Fang Anping made a concluding speech.

"Comrades, generally speaking, this verification test run is satisfactory. After the review, we unanimously decided that the LH1500 turboshaft engine has passed the verification test run!"

Immediately, there was warm applause in the meeting room.

The verification test has just passed!
in the office.

Lin Feng has been sitting in front of the computer for more than an hour, and has been crackling code words. Up to now, the third part of "Harry Potter" has been coded for more than half.

Don’t worry about the rest, just write a little if you have time, and don’t write if you don’t have time, or if you don’t have the interest in code words.

It's a great feeling not to be reminded.

After typing for more than an hour at a stretch, Lin Feng also stopped. He didn't plan to continue typing today. He made a cup of hot tea by himself, and stood in front of the large French window with the teacup, condescendingly, looking into the distance.

The field of vision is very wide, not only can you see the large area of ​​Hexi, but also the vast Qingjiang River, and you can also vaguely see the urban area of ​​​​Hedong.

"Fang Anping and the others should have finished their meeting. If there is no accident, the verification test should have passed."

"Next, should we consider the 300-hour long-term test run, and then we should also consider the prototype, design finalization and other things."

Standing in front of the floor-to-ceiling windows with a teacup in hand, Lin Feng thought a lot by himself until a knock on the door interrupted his thoughts.

"come in."

It was Fang Anping who opened the door and came in. They had already finished the verification and test run summary and review meeting. As soon as the meeting was over, he came to report to Lin Feng immediately.

"Boss, the meeting has ended just now, and the meeting review unanimously decided that the verification test run passed smoothly."

Lin Feng turned around and nodded in satisfaction, "What's next, what's your plan?"

Xiang Pingdao, "Since there is no problem in the verification test run, it means that our design is very successful. Next, I am going to start a 300-hour long-term assessment test run."

If even the 300-hour long test is successfully passed, it means that the design can be finalized, and then it can enter small-batch production in the near future.

This is a world-class turboshaft engine!
Fang Anping's heart was full of anticipation, but at the same time, he was also full of pride and gratitude.

If Lin Feng hadn't hired him from his original unit, he would probably still be doing nothing there, wasting time like that every day.

This is life!
The kind that strives for one's own ideals and can reap the results soon.

Lin Feng nodded and said, "It seems that we have thought about going together, preparing for a 300-hour long-term assessment test run, and also preparing for the start of small batch production in the future."

"Okay, boss." Fang Anping's tone was slightly excited.

Lin Feng changed the subject and reminded, "Now that our verification and test run has been successfully passed, airworthiness certification is also on the agenda, and some things can be prepared."

Airworthiness certification is a must.

Fang Anping, as an aero-engine design expert, is also very clear about the process and procedures of airworthiness certification, and said loudly, "Boss, don't worry, we are already preparing for these things."

10 minutes later, Xiang Xiang left with confidence.

In the days to come, he will still be very busy.

Such as 300-hour long-term assessment and test run, design finalization, airworthiness certification, etc., all must be completed by him leading the team.

An aircraft factory.

In the large office of the Engineering Technology Department, careful people will find that there is still a week ago's "Aviation Daily" on the newspaper shelf.

The headline on the front page of this "Aviation Daily" reported the final assembly of the first verification machine of the LH1500 turboshaft engine with both pictures and texts.

In the first one or two days, this newspaper was very popular. A crowd of technicians rushed to read it, and I don’t know how many hands passed by. It is now on the newspaper rack. It is obviously old, but it has not been cleaned up. , but continue to be there, and occasionally someone will take a look.

Of course, the main thing is to look at the report on the LH1500 turboshaft engine on the front page of the newspaper.

The clerk of the Engineering Technology Department brought in several kinds of newspapers.It is one of her tasks to go to the group every day to get new newspapers, then sort them and send them to each office.

She put about five or six newspapers and two magazines on the big table.

"Sister Liu, today's new newspaper is here again."

"Yes, today's new paper."

An engineering technician put down his work and walked over, picked up today's "Aviation Daily" and sat next to the big table to read it.

Soon, he let out an exclamation.

"My God, this is impossible!"

"Everyone, come and take a look, Leihuo Technology Industrial Group has launched another large satellite!"

His voice was loud, and with obvious surprise, he quickly attracted the attention of many people in the big office, and someone asked in puzzlement.

"Xiao Zhang, what are you doing yelling?"

"Come and take a look, the verification machine of Leihuo Technology Industry Group has completed the verification test run, and passed it once!"

This is impossible!
Several people looked up at this young technician, their eyes seemed to say, Xiao Zhang, you are joking with me.

"Xiao Zhang, today is not April Fool's Day."

"That's right, how could it be possible to pass the verification and test run in one go? You just thought about it. If you want to lie to us, you have to make up a reliable thing."

Xiao Zhang was a little anxious, raised the "Aviation Daily" in his hand, and said loudly, "The front page of the newspaper reported this matter with pictures and texts. Could it be false?"

really?
Finally someone came over, and after reading the newspaper, they also exclaimed in the same way, so several people came over one after another.

The "Aviation Daily" was spread out on this big table, surrounded by at least seven or eight technicians, some young, some in their 40s, and [-] years old, and even a senior engineer with gray hair and reading glasses .

"Really, I can't believe it!"

"It is a miracle to pass the verification and test run at one time!"

"This is a world-class turboshaft engine. It has already passed the verification test. I feel like I am dreaming."

Gradually, many people surrounded the big table, all of them were amazed, and some people even showed admiration on their faces.

Suddenly, someone said loudly, "Zhao Manzhi, didn't you say last time that if this engine can pass the verification test, you will eat it in one bite?"

There is such a thing.

Last time, the front-page headline of the "Aviation Daily" reported that the LH1500 turboshaft engine entered the final assembly and was preparing to verify the test run.

Zhao Manzhi said in front of everyone that if the engine finally passed the verification test, he would eat the engine raw.

As a result, they passed the verification test run in one go.

It is not repeated N times at all, and then it is difficult to pass the verification test.

Many people looked at Zhao Manzhi, and some of them had playful expressions on their faces.

"Xiao Zhao, you can't break your word, you have to keep your promise."

"You don't need to eat that engine raw, after all, that engine is too expensive, so just eat this newspaper raw on the spot."

Haha
Many laughed happily.

Zhao Manzhi's face was flushed, knowing that he couldn't hide, so he had to stand up, very embarrassed, and hesitantly said, "This, this, it was just a joke at the time, yes, I was joking."

After the "Aviation Daily" report, several newspapers, magazines, and periodicals, which are very influential in the domestic aviation industry system, have reported this matter one after another.

So, in just a few days, almost the entire aviation industry system knew about this matter, and knew that a world-class turboshaft engine was launched in Leihuo Technology Industrial Group, and it miraculously passed the verification test at one time.

In a short period of time, this engine has gained a lot of fame in the industry.

Anyone who works in the aviation industry system basically knows that there is such an excellent turboshaft engine in Leihuo Technology Industrial Group.

Leihuo Technology Industrial Group, aero-engine assembly workshop.

Under the guidance of the technicians, the workers started to assemble the engine again according to the assembly process.

It was disassembled a few days ago and was disassembled into parts. Almost every part was carefully inspected and no problems were found.

Now, turbine unit, compressor unit, combustor unit, reducer unit, accessory unit are all starting to assemble.

It can be seen that after the first assembly experience, the workers are more proficient, and because this engine has been assembled once, there is no need to do a lot of work again.

Such as the assembly of the turbo unit.

Workers no longer have to weigh each turbine blade, nor do they need to balance the turbine disk.

I saw a worker skillfully put the turbine blades into the mortise of the turbine disc, and seated them in alignment. The No. 1 turbine blade was inserted into the No. 1 mortise, and the No. 2 turbine blade was inserted into the No. 2 mortise.

Turbine blades and turbine disc tongues and grooves are numbered, so that the assembly speed of the numbered seat type is relatively fast.

From the beginning of the assembly of the unit parts, it took only two days for this turboshaft engine to enter the final assembly of the whole machine.

In the smoking room, some workers were smoking while chatting about the engine.

"The final assembly of the whole machine started again so soon, which is much faster than the first time."

"After the final assembly of the whole machine is completed, what will be done next?"

"Well, I guess you have to ask the leaders to know."

"."

The aircraft assembly workshop has already started the final assembly of the whole aircraft, and the test workshop has also begun to get busy. Xia Yang brought a few technicians and a large group of workers to prepare for the work.

There are workers and technicians in both the test bench and the test control room, and everyone is preparing for another test run.

"Director Xia, it's really a 300-hour long test."

"Yes, the 300-hour long-term assessment test run will start soon, so our preparations must be sufficient, and various inspections must be careful."

Xia Yang repeatedly urged that the 300-hour long test is not only a huge test for this turboshaft engine, but also a test for the entire test bench.

During such a long test run, there must be no problems in the test run, and everything must keep up.

The aircraft assembly workshop, the test workshop and others are busy, preparing to start the 300-hour long-term test run. The two major processing workshops are also busy. Workers continue to process and manufacture various parts of the LH1500 turboshaft engine.

In addition to the 300-hour long-term test run, the two workshops have already started preparing for small batch production in advance.

in the office.

Lin Feng came back from the manufacturing site just now. He not only went to the aircraft assembly workshop, but also went to the two major manufacturing workshops.

Sitting on his boss chair, Lin Feng thought in his heart that the 300-hour long-term test run is about to start, and the small batch production will also be ahead of schedule. The design of our helicopter and the construction of the helicopter manufacturing plant will continue Speed ​​up the job.

Well, I will go to the Helicopter Design Institute tomorrow, and also take a look at the Helicopter Manufacturing Plant under construction.

While thinking about these things, the phone on the desk remembered.

Lin Feng picked up the phone, and Lin Qiong's voice came from inside.

"Brother, I have no money again, and all the money has been used up."
