Chapter 340 Mr. Lin's Lectures, Still Popular
Hearing vaguely that it was Mr. Lin calling, many people pricked up their ears.

Almost everyone noticed Fang Anping's expression. As soon as the phone was hung up, someone couldn't help asking, "Mr. Fang, is Mr. Lin really going to teach us?"

At this moment, Fang Anping felt extremely relaxed, and said loudly, "Yes, at two o'clock in the afternoon, Mr. Lin will tell us about the specific design of the fan part!"

Suddenly, cheers erupted in the meeting room!
"Great!"

"There is hope. With Mr. Lin's explanation, we have the confidence to design the fan part of this engine!"

"Haha, this is the most exciting news I've heard!"

"."

Seeing everyone's great reaction, Fang Anping waved his hand and said loudly, "Go ahead, at 1:[-] in the afternoon in meeting room [-], all design experts, all design backbones and supervisors of the fan department will come on time to listen to Mr. Lin's lecture. , others are willing to come and listen to it if they want to.”

Another burst of cheers!

At this moment, the conference room was completely different from the oppression and dullness before. There was only joy and relaxation left. With Lin Feng as the backbone, everyone suddenly had unprecedented confidence.

The notice spread quickly, and everyone in the design room of the fan department was notified. Needless to say, those design backbones and supervisors were already making preparations for attending lectures in the afternoon, and the other designers were also highly motivated.

"Boss Lin is giving a lecture to everyone, so you must go and listen to it!"

"Boss Lin is so awesome, I can't help but admire him!"

"Lin is always my idol, if you don't follow the stars in this generation, you will follow the super idol Mr. Lin!
"."

Those ordinary designers with slightly older qualifications who have been working for one or two years all know the effect of Lin Feng's lectures, and also know Lin Feng's super high technical level, and they all express their desire to go and listen to it.

Those new designers who joined Leihuo Aviation Engine Design Center not long ago were secretly surprised, and even quietly asked some old designers.

"Zhang Gong, why are you all so excited!"

"Of course, this is Mr. Lin himself telling everyone about the design of the fan part of this engine."

The new designer was still a little puzzled, and continued to ask, "Is Mr. Lin so powerful? We have several design experts in the fan part, and they can just give you lectures."

Zhang Gong smiled, with an expression of "you don't understand this, right?" "Xiao Li, listen to my brother, and you will know after listening to Mr. Lin's lecture in the afternoon."

At 01:30 in the afternoon, this conference hall, which can accommodate nearly 300 people, was already full of people. The large conference room was extremely lively. Although some seats were vacant, laptops had already been placed, and the seats had already been occupied.

"Huang Yiming, you are engaged in the design of compressors, did you also come to attend the class!"

The young designer named "Huang Yiming" smiled and said loudly, "Look, it's not just me. At least 30 to [-] people have come from our design studio, even our director Zhang has come."

is not that right!

Not only Zhang Xu, the director of the compressor design department, Wang Jianshu from the combustion chamber design department, Hua Jingsheng from the turbine part design department, but even Ding Zhigao from the accessory design department came here. Several of their directors were sitting in the front seats, There was talking and laughing.

Hearing Mr. Lin's lecture and explaining the specific design of the fan part in detail, the people in the Leihuo aero-engine design room were simply moved by the news, and the large conference room that can accommodate nearly [-] people was full in a short time.

Fang Anping and several design experts are drinking tea in the office, chatting about the design of this engine, and will go there together in a few minutes to listen to Mr. Lin's lecture.

Even at the expert level, everyone still found that listening to Mr. Lin's lectures is still very rewarding!
At this time, Fang Anping's assistant ran over and reported anxiously, "Mr. Fang, the conference room is full. Do you want to change to the big training room?"

Leihuo Aviation Engine Design Center has several large training rooms, which can generally accommodate two to 300 people, and the largest two rooms can accommodate 500 people to attend classes.

Fang Anping was slightly startled, and said in disbelief, "The fan design room is full and there are only more than 200 people, and the total number of design directors and design backbones is only three or no. 40 people. Our large conference room is already It's full."

"It's full, all the seats are full, and many people will come." His assistant said, "All the people from the Fan Design Office will come to attend the class, and it is estimated that no one will be left, and then other design offices will also come. Not many people, even the annex design room has at least a dozen people."

Oh my God!

There are so many people, that's really sloppy!
Fang Anping knew that every time Mr. Lin gave a lecture, many people always came, but considering that this time he mainly talked about the specific design of the fan part, which was very targeted, he thought that the No. [-] conference room that could accommodate nearly [-] people would be Enough is enough, how do you know it is not enough.

Raising his hand to check the time, there are still 7 minutes before two o'clock, and there is still a little time, and he immediately said, "Hurry up and inform everyone that the class location will be changed to training room No. [-]."

After speaking, he called Lin Feng himself again, briefly talked about the hot situation, and also said that the class location was changed to No. [-] training room.

Training room No. [-] should be enough, because it can accommodate a full [-] people!
Soon, a large number of people poured into this training room. It was a miracle that this training room was almost full at around two o'clock in the afternoon.

Accompanied by Fang Anping and others, Lin Feng walked into this large training room. Not only did he hold several design drawings in his hand, he even made slides that had been prepared in advance.

As soon as Lin Feng appeared, the lively training session suddenly fell silent, and then burst into warm applause.

The applause slowly reminded everyone to sit up straight, with sharp eyes, ready to attend the lecture.Fang Anping and the others also sat down in the first row, opened their notebooks, held a square pen, and prepared to listen carefully to the class and take notes seriously.

Lin Feng looked around the entire training room, seeing four or five hundred pairs of eyes looking at him, he nodded slightly, "Everyone, today I will mainly tell you about the fan design of this engine."

Just be happy and see the mountain, no nonsense!
First of all, I gave a general description of the design ideas of the fan, the performance to be achieved, etc. It took about ten minutes, and then I started to describe the specific design.

"We all know that the most important part of a fan is the fan rotor, and the most important part of the fan rotor is the fan blade. Let's talk about the specific design of the fan blade."

While talking, he displayed the design drawing of the first-stage fan blade and posted it on the blackboard in the large training room, preparing to give a specific explanation based on this design drawing.

"My God, this is the design drawing of the fan blade!"

"Boss Lin is amazing, it is estimated that he drew the design drawing himself!"

"I've never seen this kind of fan blade, could it be the legendary wide-chord fan blade!"

"."

The design drawings were posted one by one, and immediately, the originally quiet training room became a little commotion, and many people quietly talked and communicated with those next to them.

Even Fang Anping and the others were the same, their eyes lit up one after another, and they communicated softly with each other.

"The boss is amazing, the drawings of the fan blades have been drawn!"

"That's good, the design difficulty plummets!"

"This is a wide-chord fan blade, and it is made of carbon fiber composite material. The blade shape seems to be different from the general wide-chord fan blade!"

"."

Fang Anping and the others are design experts after all, and they can see the difference in the blades of this wide-chord fan at a glance.

Seeing everyone's commotion, Lin Feng smiled slightly, indicating that the attack should be quiet first, and then began to explain in detail the design of this fan blade, the design principle, the design parameters of the blade shape, including why it is designed in this way, and what advanced design concepts it has. etc.

This lecture is nearly an hour.

Take a short break, and then resume speaking.

This time I talked about the design of the fan casing, and it took another hour. In the remaining time, I also talked about the design of the fan wheel and fan rotor, all of which have design drawings or slides.

Everyone was so enthralled!

It turns out that the fan of this engine is designed like this!
suddenly see the light!
Again, these design experts and design backbones seem to have entered a brand-new world, and what they have come into contact with is brand-new design theories and concepts, like a piece of dry sea being put into the water, absorbing these design knowledge crazily.

Lin Feng raised his hand to check the time, and said, "That's all for today, I'm going back to bring my son, you guys should digest and understand what I'm talking about."

Many people laughed in good faith.

It never occurred to Mr. Lin to be so down-to-earth that he would go home to take his son.

After Lin Feng left, the huge training room became lively with a "boom". Almost everyone was beaming and chatting loudly about the things that Lin Feng explained. It was obvious that everyone gained a lot.

"Mr. Fang, I'm suddenly enlightened now!"

"Me too, it was designed like this!"

"Boss Lin's level is really high!"

Everyone was in admiration, Fang Anping also nodded vigorously, and he also benefited a lot.

With Lin Feng's lecture this time, and the design drawings of these key and important parts of the fan part drawn by him, the fan part of this engine has been fully designed, and there is basically no technical difficulty for everyone. .

What Lin Feng has to do is to guide occasionally, so that the design does not deviate, and it is enough to maintain the consistency with the system design.

Next, besides instructing everyone in designing and giving lectures, Lin Feng also drew a lot of design drawings one after another.

Not limited to this large bypass ratio turbofan engine, including this large military transport aircraft, Lin Feng also drew a lot of design drawings, or design sketches, and often guided everyone's design work.

Phoenix City, Central Plaza.

This is the busiest center of the city. There are not only department stores, but also the four-star Golden Dragon Hotel. What is particularly eye-catching is this landmark building under construction.

Because the construction project is much less difficult than the Leihuo Technology Building, its main body height now exceeds 100 meters, almost catching up with the construction height of the Leihuo Technology Building.

In the dining hall of the Golden Dragon Hotel, a group of designers from the Phoenix Aero-Engine Design Institute eat here. Through the window glass, you can see the building under construction opposite.

Sitting in the main seat was Zhong Jianming, the deputy director of the Phoenix Institute and the chief designer of a certain type of engine. The people sitting next to him were all the design backbones, or the middle and high-level people of the Phoenix Institute.

Including Wei Yuhang, the first overseas returnee doctor of Phoenix Institute, who is also the most educated talent introduced by Phoenix Institute for decades.

Wei Yuhang was in his early forties, wearing a pair of glasses, a shirt, and a tie. He looked very energetic, not like an engineer engaged in aero-engine design, but more like a teacher in a university.

Zhong Jianming admired Wei Yuhang very much and planned to train him as his successor. At present, one of the most important projects of the Phoenix Institute is also entrusted to Wei Yuhang, which is the design and development of wide-chord fan blades.

This is a design pre-research, a technical research carried out in advance for the future independent research and development of advanced turbofan engines.

"Yuhang, I heard that you have made a breakthrough in the research and development of wide-chord fan blades. Congratulations. Come and congratulate you."

Zhong Jianming took the initiative to pick up the cup.

Wei Yuhang didn't dare to be negligent, and quickly raised his wine glass. After joining the team of Phoenix Institute, he realized more and more the profoundness of the domestic wine table culture, "Mr. Zhong, thank you, I will fuck you, you can do whatever you want."

He generously drank a full glass of white wine in one go.

Zhong Jianming nodded appreciatively, and felt that Wei Yuhang was worth cultivating, with skills, abilities, and a good man.

"Yuhang, your wide-chord fan blades will enter the design verification stage."

Wei Yuhang nodded, "Yes, the design work has been completed, and the next step is to manufacture a batch of blades and verify whether they meet the design requirements."

He briefly talked about the current situation and his plans for the next step.

Design first, then conduct design demonstration. If it is successful, it means that the design is reasonable and successful. If there are problems, then analyze the problems, then improve and improve the design, and then carry out design verification until it becomes a success.

Someone reminded, "Director Wei, Leihuo Aviation Engine Design Center is working on high bypass ratio turbofan engines. I heard that the fan blades are also designed with wide-chord blades."

"Oh, there is such a thing." Wei Yuhang's heart moved slightly, it was the first time he had heard of such a thing.

Although Phoenix Aero-Engine Design Institute is also located in Fenghuang City, there are not many intersections with Leihuo Aero-Engine Design Center, and even fewer people know that Leihuo Technology Industrial Group is also designing wide-chord fan blades.

But there are always some well-informed people who learned something through some channels, such as the design director in front of him, who broke the news that Leihuo Aero Engine Design Center is also working on wide-chord fan blades.

Wei Yuhang can’t help thinking, what about the wide-chord fan blades of Leihuo Aero-Engine Design Center? Compared with the wide-chord fan blades designed by himself, how big is the gap between the two, and whose wide-chord blades are better.
After dinner, he returned to his office and was still thinking about it.

in the office.

Lin Feng made a cup of coffee himself, sat on the large and comfortable boss chair, and was reading the latest issue of "China Airlines". This is a technical journal with two issues in January, and it is regarded as the most authoritative journal in the field of domestic aviation industry.

The number of subscriptions is also relatively large. The entire aviation industry system and various aviation industry companies have subscribed in large quantities, and many technicians will read this journal.

Lin Feng doesn't have to read every issue, he just flips through it occasionally. He mostly reads more professional foreign technical journals, which are in full English.

Today I specially picked up this issue of "China Airlines" and read it, mainly because there is an article of my own on it, the design of wide-chord fan blades.

Why did I write this professional paper and publish it in "China Airlines"? It started 20 days ago.

The editor-in-chief of "China Airlines" specially called and invited Lin Feng to write a paper with a very sincere attitude, because if an article by a technical expert like Lin Feng is published on "China Airlines", it will invisibly improve the journal's reputation. The grade is also more compelling.

Helpless, the editor-in-chief's attitude was too good, and Lin Feng also sold him a favor. In addition, the system had just completed the design of this large transport aircraft, so Lin Feng wrote a professional thesis on the design of wide-chord fan blades.

Why write a design paper on wide-chord fan blades?

The main reason is that domestic design on this aspect is almost blank, and domestic colleagues basically have no technical materials to refer to. I hope this paper will be helpful to them.

If the wide-chord fan blades are divided into three generations, the first generation is a titanium alloy honeycomb core, and the outer layer is a titanium alloy cover.The second generation is still a titanium alloy honeycomb core, but the covering layer is generally a composite material.The third generation is a systematically designed carbon fiber composite hollow wide-chord blade.

Lin Feng's paper does not involve the third-generation wide-chord fan blades, but also writes about the design of the second-generation wide-chord fan blades, which is estimated to be of great help to domestic counterparts.

Before the third-generation wide-chord fan blades come out, the second-generation wide-chord fan blades should be considered the most advanced in the world, which is enough for domestic counterparts.

After flipping through this issue of "China Airlines", Lin Feng nodded in satisfaction. Apart from the first one being his own paper, there are several professional papers written by technicians of Leihuo Technology Industry Group, or Engineer's hand.

After drinking coffee and putting this issue of "China Airlines" aside, Lin Feng began to draw the design sketch of this large military transport aircraft on his computer again.

The workload of the design sketch is much smaller. It is no problem to draw three or five in a day. Each design sketch only needs to mark a few key and main dimensions, and draw the design structure clearly. This is how the design sketch is right Everyone's help is also great.

Phoenix Aero Engine Institute.

Wei Yuhang had just finished a meeting, sat in an office chair, and saw the latest issue of "China Airlines" sent over, so he looked at it seriously.

Soon, he saw Lin Feng's professional paper on the design of wide-chord fan blades.

Guys, it’s [-] words again, please help me vote for a few monthly tickets or recommendation tickets, thank you!
