Start with the aviation industry

Chapter 198 Zhou Yuanliang is willing to be a student
what!
Just overcame the key technical difficulties of the composite material rotor, and encountered a thorny problem!

As a good friend, Zhao Mingzhi asked with concern, "Old Zhou, what technical problems have you encountered?"

"It's not really a technical problem," Zhou Yuanliang replied.

"Then tell me what happened, maybe I can help."

"It's like this." Zhou Yuanliang briefly explained the situation.

Suddenly, Zhao Mingzhi's heart lightened.

That's what happened!
"Old Zhou, do you know what kind of bearings our turboshaft engine will use?"

Zhou Yuanliang said, "Such an excellent turboshaft engine must use imported bearings."

Zhao Mingzhi smiled and said, "Then you guessed wrong. Our turboshaft engine will use domestic bearings in the future. In addition, the transport helicopter we are designing and developing will also use domestic bearings in the future."

what!
All use domestic bearings! ! !

Zhou Yuanliang said in a tone of disbelief, "Old Zhao, you are not joking with me, this is impossible!"

"How is this possible?" Zhao Mingzhi said affirmatively, "Our boss bought a professional bearing manufacturing plant in Shenhai City. The bearing samples of this turboshaft engine have been manufactured and have undergone professional quality inspection."

He briefly explained the situation.

Finally, Zhou Yuanliang couldn't sit still anymore.

"Really, that's great." Zhou Yuanliang's tone was obviously surprised, "Old Zhao, I'll come to your place right away, and buy a train ticket right away!"

The next day.

Lin Feng went to Leihuo Helicopter Design Institute.

"Director Zhao, these are the last few design drawings. From today onwards, I will no longer draw the design drawings myself, but instead guide everyone to carry out specific design work."

Zhao Mingzhi happily took these design drawings, unfolded them for a little look, and was very happy, because they were all the design drawings of the most critical, most important, and most difficult parts of this transport helicopter.

So far, at least the key and important components with the most technical difficulty, and even the general design drawings of several major systems, have been drawn by Lin Feng.

Zhao Mingzhi said, "Boss, you have personally drawn so many design drawings. We are deeply inspired and have full confidence in the design of this transport helicopter."

Then, he reported to Lin Feng the progress of the design in the recent period.

Overall, the design progressed very quickly.

Now it is really on the right track. The number of design technicians in the design office has increased from more than 100 to 400 to [-] now.

The entire organizational framework has been fully set up. The design office has set up an expert room and several design offices, each with dozens of people.

It is estimated that another two to three hundred people will be recruited. When the number of design technicians in the design office reaches about six to seven hundred, and each design office has more than one hundred people, it will basically take shape.

To be honest, at least two-thirds of the 700 to [-] people are tool people. According to Lin Feng's technical guidance, the design is carried out with reference to these already drawn design drawings.

Less than one-third of people need to think independently and rely on their own technical level to design some parts.

Zhou Yuan got on the train before dawn, and got off the train at this time. He took a taxi outside the train station and headed directly towards the Leihuo Helicopter Design Institute.

He has been here once and is no stranger to this place.

Get off the car, register at the gate, and go directly to Zhao Mingzhi's office.

"Old Zhao, I'm here."

Zhao Mingzhi said enthusiastically, "It's coming so soon, you just happened to come, and our boss also just came over, and he is going to tell everyone about the design of the helicopter's power system."

What a coincidence!

Zhou Yuanliang is engaged in the design of the power system of the helicopter, and his technical team is conducting pre-research on some key technologies of the power system of the medium-sized special-purpose armed helicopter in the future.

In addition to the key technology of the composite material rotor has been overcome, they are also facing several key technologies that have not been overcome.

Zhou Yuanliang immediately became interested, "Old Zhao, can you talk to Boss Lin for me, I want to sit by and listen."

Zhao Mingzhi smiled and said, "Old Zhou, you are a professor-level senior engineer and a well-known expert in helicopter power system design. You are willing to be an auditor."

Zhou Yuanliang smiled, "I definitely don't want to be someone else's auditor, but I am willing to be Mr. Lin's auditor!"

"Okay, let me ask you a question later."

In the training classroom.

At least 50, NO.[-] people have been seated, and people are rushing over one after another. There are more and more people in the classroom, and there are fewer and fewer vacant seats.

Mr. Lin gave lectures to everyone. Hearing the news, many designers came over on their own initiative, not just from the power system design room.

"Liu Gong, Mr. Lin will tell you about the design of the helicopter's power system later, let's go and listen."

In the structural design interior, a young designer said so.

Another designer said, "Boss Lin is talking about the design of the power system. We are engaged in the design of the helicopter structure. There is no need to go and listen."

A slightly older designer was preparing to go out with a notebook, and suggested, "You don't understand this, Mr. Lin's level is very high, listen to him, even if it is the design of the power system, I am still It feels like it should be useful for our design work.”

"That's right, I'm going to listen to it too." Another designer said, "I just listened to Mr. Lin's class last time, and I feel that I have gained a lot and benefited a lot."

More and more designers came to listen to Mr. Lin's lectures. Gradually, the training classroom that can accommodate nearly a hundred people was full.

Some people who came late could only stand at the back of the classroom, or bring stools from outside, and those who came later could only lie on the outside of the window.

At ten o'clock in the morning, Lin Feng walked into the training classroom.

Seeing so many people listening to his class, Lin Feng was still satisfied. He walked up to the podium, looked around the entire classroom, raised his hand and pressed down, "Everyone calm down, we will start the lecture now."

The lively and noisy classroom quickly quieted down. Lin Feng turned on the slide projector, took the first slide from the prepared slides and put it down.

Just as he was about to tell everyone about the design of the helicopter's power system, Zhao Mingzhi walked over quietly and whispered in Lin Feng's ear.

"Boss, Zhou Yuanliang just came over. I heard that you are going to tell everyone about the design of the helicopter's power system. He wants to come and sit by the side and listen."

Lin Feng nodded, "Yes, but remember to tell him to bring the stool yourself, as there is no room left."

"Okay, I'll call him over."

Zhao Mingzhi trotted all the way to inform Zhou Yuanliang.

"Old Zhou, Mr. Lin has started to give lectures. I agree with you to attend the lecture, but I have to move a chair by myself."

Zhou Yuanliang was stunned for a moment, thinking in his heart, what the hell is that if he moved a chair over by himself.

Zhao Mingzhi saw his doubts and explained, "The training room for the class is already full. If you don't move a chair there, there will be no place to sit."

It turned out to be the case.

Zhou Yuanliang suddenly realized.

He smiled and said, "So that's what happened, okay, I'll go there now."

He really moved a chair over there, and he was startled before he reached the door of the classroom. My God, even the window sill was full of people.

Mr. Lin was so hot in class.

He quickly moved the chair and squeezed in from the front, but there didn't seem to be many places in the classroom. He looked around for a while, trying to find a place where he could put the chair.

Lin Feng nodded slightly to Zhou Yuanliang, and seeing him looking around to find a place, he also said loudly, "President Zhou, come here, there is still a little space."

That's next to the podium, about halfway there.

Lin Feng said loudly again, "You guys squeeze a little bit to make room."

In this way, Zhou Yuanliang put down his chair, finally had a place to sit, and felt relieved.

The lecture is about to begin.

The classroom became quiet again, and everyone looked at the direction of the podium together, waiting for Lin Feng to give everyone the design of the power system of this transport helicopter.

The power system is undoubtedly one of the most critical and important systems of a helicopter.

It is technically difficult and very complex.

It mainly includes: turboshaft engine, reduction gear, transmission, rotor, tail rotor and other parts.

Lin Feng's voice was so loud that everyone could hear him clearly without a loudspeaker. He began to tell everyone about the design of the power system of this transport helicopter.

Needless to say, the turboshaft engine uses two LH1500 turboshaft engines with a total output of 3052 kilowatts.

First, he explained the power system of this transport helicopter in general, and then, Lin Feng began to talk about the design of several key components one by one.

Such as reducer.

It is one of the main moving parts on the helicopter, and it is also the most complex, largest and heaviest part of the transmission.

The reducer on this helicopter is systematically designed, with the characteristics of large transmission power, light weight, long service life, high reliability and convenient maintenance.

There is a schematic design diagram of the reducer on the slide, and the working principle and design features are very clear. Lin Feng explained it in detail based on the slide, especially some key technologies are very thorough.

The classroom is very quiet!

Only the sound of people taking notes and flipping notebooks.

Zhou Yuanliang was also taking notes, and his mood was agitated.

He quietly took deep breaths several times, trying to calm himself down, but it was difficult to control his agitated mood, because the design of this reducer was so advanced, it was simply a groundbreaking design.

As far as he knows, even the advanced foreign helicopter companies do not have such a design, Leihuo Technology Industry Group is too good.

He didn't know, it was designed by the system.

Produced by the system, it must be a boutique!
After talking about the design of the main reducer, Lin Feng then talked about the design of important components such as the rotor system, automatic tilter, transmission mechanism and drive shaft.

For two hours, from 10:12 am to [-]:[-] am, there was no pause, and the speech was finished in one breath.

Almost no one left in the middle, and it was rare to go to the toilet or go out to smoke, because everyone was reluctant to leave, and was afraid that they would miss some important things during the few minutes of leaving.

"Okay, that's all for my explanation. I'll continue here in the afternoon, mainly answering the technical problems you encountered in the design, as well as design guidance for some important components."

The sound fell.

There was warm applause in the classroom.

The same was true for Zhou Yuanliang, who applauded vigorously. The two hours of listening in was a huge gain for him. Some key techniques, which he was relatively vague at first, are now relatively clear.

He is confident that as long as he is given some time, he should be able to lead the technical team to overcome some key technologies in the power system.

Lin Feng was the first to walk out of the classroom, then Zhao Mingzhi followed behind, Zhou Yuanliang was also faster, and immediately moved the chair to follow.

The classroom was completely lively.

"Boss Lin is so awesome!"

"This is a real technological giant. After listening to Mr. Lin, I have confidence in the design of the power system."

"Two hours, it feels like it passed in a flash."

Many people did not leave immediately, and discussed enthusiastically in the classroom. These two hours were a huge gain for them.

Of course, some people also talked about Zhou Yuanliang.

"The person who came in with the chair in the end is very strange, he is not from our institute."

"I know him. He came here two or three months ago. Mr. Lin was telling everyone about the design of the composite rotor. He also sat in the classroom and listened."

"His name is Zhou Yuanliang, a professor-level senior engineer, and an expert in the design of a helicopter power system in China."

what!
Quite a few people were surprised when they realized Zhou Yuanliang's identity!
It took half a day to react!
Such an expert actually came all the way to listen to Mr. Lin's lecture. If he didn't see it with his own eyes, who would believe it?

Inside the office.

Zhao Mingzhi brewed several cups of hot tea with his own hands, one cup for each person.After talking for two hours at a stretch, Lin Feng really wanted to take a sip of hot tea, so he was the first to pick up the teacup, blew on it gently, and took a sip.

"Mr. Lin, after listening to your lecture, I think there should be no more problems with the design of the power system of this helicopter."

Lin Feng said, "I need this effect. I hope our helicopter can be designed sooner."

Zhou Yuanliang's mood was still turbulent, because the harvest was too great, the harvest in these two hours was greater than the harvest he had gained in two years of hard work.

"Boss Lin, thank you for letting me listen in."

Lin Feng smiled, "It's all for the domestic aviation industry. Thank you for what I'm doing. I also hope that you can produce this medium-sized special-purpose armed helicopter that the military needs earlier."

"Well, we'll try."

After drinking a cup of tea, Lin Feng thought about where to eat.

Zhou Yuanliang first proposed, "Boss Lin, in order to express my gratitude, I would like to treat you to a light meal at noon today."

Lin Feng said straightforwardly, "Yes, but I can't drink at noon, and I have to guide everyone in the design work in the afternoon."

Zhou Yuanliang said, "Can I still listen in this afternoon?"

Lin Feng said, "Of course."

Immediately, Zhou Yuanliang became happy in his heart, and even temporarily forgot the purpose of his visit this time.

He came here from hundreds of kilometers away, originally not for the purpose of listening in, but for bearing matters.

"Come on, let's go eat first."

A group of people crowded Lin Feng out of the design office without taking a car, because Zhao Zhiming said that there was a good restaurant nearby, and it was only a few minutes' walk away.

In the afternoon, Lin Feng answered some technical difficulties in the design, guided everyone's design and so on.

Zhou Yuanliang was by his side the whole time, like a follower, listening and taking notes seriously.

From 05:30 p.m. to [-]:[-] p.m., three and a half hours later, Lin Feng left by car and returned to Phoenix City.

Zhao Mingzhi said, "Old Zhou, today's harvest is pretty big."

"After one day today, I feel that my technical level has improved, Mr. Lin is too good."

After expressing his emotions, Zhou Yuanliang was also slightly puzzled, and asked, "Why is Boss Lin so powerful and has such a high level of professional skills?"

Zhao Mingzhi said, "If you had the opportunity to sit in Mr. Lin's office, you wouldn't have such questions."

"why?"

"The bookshelves in Mr. Lin's office are full of professional books. He basically reads one book in a few days. After a long time, he has read countless professional books. It's no wonder his professional skills are not high."

Zhou Yuanliang said, "Seeing that I have to not only come over and listen to it frequently, but also insist on reading every day."

The two chatted for a while, the sky outside was slightly dark, and it became a little dim, Zhao Mingzhi said, "Come on, let's go have dinner together, and sleep at my house at night."

All three of his family have moved here and bought a house in the provincial capital with the settlement funds. It is a three-bedroom house with room to sleep.

The two left the design office together, found a restaurant outside, ordered a few dishes, ordered a bottle of wine, and continued chatting while eating and drinking.

Of course it's about helicopter design.

In addition to talking about these, Zhou Yuanliang also chatted about some things about their unit, such as who has been promoted again, who has retired, and so on.

In the end, Zhou Yuanliang didn't stay at Zhao Mingzhi's home, but at a nearby hotel.

After washing, he sat down, opened the notebook and read the contents on it again, thinking about it while reading it, to deepen his memory and understanding.

Mr. Lin is really awesome.

I heard that many of the key and important parts of this transport helicopter were designed by him himself, even the general diagram of the reducer of the power system and the general diagram of the transmission device were drawn by him himself.

Great!

Simply a bull.

Zhou Yuanliang originally thought that his professional skills were already very powerful, but now he knows that there is a sky beyond the sky, and there are people beyond people.

Keeping this humble heart, he read the contents of the notebook from beginning to end.

After reading this, I was a little tired, so I went to bed.

Lying on the bed, he first thought about the scene of today's audition in his mind, and gradually thought about the power system of the special armed helicopter he presided over the design.

The key technology of the composite rotor has been overcome, and several other key technologies of the power system are also much clearer. He is confident to lead the technical team to overcome them one by one.

After thinking about these things, he suddenly remembered and forgot the most important thing.

Oh my God!

What's wrong with me.

I came here hundreds of kilometers from the institute, mainly for bearing matters. Once Mr. Lin was an auditor, I completely forgot about this matter!
That's [-] words today.
