Chapter 265 Turbofan Engine Design Fully Launched

The trip to Deep Sea City went very smoothly.

After arriving, he met Xie Kangquan soon, and then met some people in Shenhai City, and the three parties signed an agreement.

This piece of industrial land with an area of ​​more than 800 mu was given to Leihuo Technology Industrial Group without compensation for the production and manufacture of aero-engines and shall not be used for other purposes.

Leihuo Technology Industry Group promises to complete the test run of the verification machine within three years and pass the user review.

If it is not completed, Leihuo Technology Industry Group must buy the land at the market price.

"Boss, congratulations!"

After the agreement was signed, Ding Haixia was the first to congratulate Lin Feng, followed by Fang Anping and others.

"Boss, congratulations. In this way, we will have the land to build a professional turbofan engine manufacturing plant."

"Boss, I feel like I'm dreaming, such a large piece of land was given to us like this."

"..."

Lin Feng smiled happily, and did not hide his inner joy in front of everyone. He said loudly, "The land for the construction of the factory has been obtained, and the next step is the planning and construction of the factory, as well as the design and development of our engine."

Fang Anping was still under a lot of pressure, the requirements of this engine were too high.

"Boss, we are looking forward to it, but also under pressure. We are really not sure."

Lin Feng smiled, "What are you afraid of? I'm the one to do everything. It's still the old rule. I will draw the general design drawings of some engines, and some key and important parts by myself."

Fang Anping and the others were stunned!
Everyone stared blankly at Lin Feng!

My God, it seems that the boss has a high level of technology in the design and development of turbofan engines!

"Boss, you can really draw out some design drawings, so that we can be sure."

Lin Feng said, "I will not only draw some key design drawings, but also guide you through the entire design process."

Immediately, Fang Anping and the others lightly stood up, and some even remembered the design process of the LH1500 turboshaft engine.

If this engine is the same, it is estimated that it will not take three years at all, and it may enter the verification test run in about two years.

Back at Leihuo Technology Industrial Group, Lin Feng started to draw the general design of this turbofan engine without stopping.

Lin Feng's CAD is very easy to use, and he completed the general design drawing of the engine in only two and a half days. There are three design drawings in total, including a design drawing of No. [-].

.........

Zhu Zhiwen was a little disappointed. The supply of Russian-made engines they needed was really limited, and the other party only sold 4 units in the first batch.

The reason is also very simple. The other party said that this fighter has not been successfully developed, and 4 engines are enough to produce 4 prototypes.

That's right, this is a multi-purpose light fighter. It uses a single-engine design, and each one only needs one engine.

Even though what the other party said was very reasonable, Zhu Zhiwen still felt that things might not be so simple. After this fighter plane enters mass production, it is estimated that the limited quantity will still be the same.

While thinking about these things, the phone on the desk rang, and Xie Kangquan called.

"Old Zhu, I feel a little uncomfortable, I'm a little disappointed."

Knowing that Xie Kangquan was talking about the fact that the other party only sold 4 engines in the first batch, Zhu Zhiwen sighed softly, "Oh, thank you for understanding me."

Xie Kangquan smiled easily, "There are only 4 units in the first batch, let's make 4 units, don't worry too much."

Zhu Zhiwen said, "Old Xie, it's easy to say, what if the opponent's engine is restricted after our fighter jets are mass-produced?"

"So, domestically produced engines are better, and there is no need to worry about sales restrictions and bottlenecks. Unfortunately, we are still unable to develop such engines in China."

Xie Kangquan smiled and said, "Old Zhu, who said that we can't develop such an engine in China, you should pay more attention to Leihuo Technology Industrial Group."

Of course Zhu Zhiwen knew Leihuo Technology Industry Group, but recently he was busy with the design and development of this fighter plane he presided over, especially the engine, so he really didn't pay attention to the current situation of Leihuo Technology Industry Group.

"Old Xie, is Leihuo Technology Industry Group planning to launch a turbofan!"

"Yes, your guess is completely correct." Xie Kangquan said, "They are going to design and develop a small channel ratio military turbofan engine..."

He briefly introduced this engine by the way, because he had seen the design technical outline of this engine and understood the design parameters of the engine.

what!
This is impossible! ! !
Zhu Zhiwen said in an unbelievable tone, "If this is really the case, it is the world's top engine. Can they really succeed?"

Xie Kangquan said, "I am very optimistic about them. If you are interested, I suggest you go to Leihuo Technology Industrial Group to take a look."

Immediately, Zhu Zhiwen was more excited.

After putting down the phone, the more I thought about it, the more I felt that Xie Kangquan's suggestion was good, in case there was a surprise waiting for him.

.........

Lin Feng did it himself, starting with the general drawing, such as drawing the general design drawing of the entire engine, then drawing the general design drawing of the fan and compressor, and then drawing the general design drawing of the combustion chamber, turbine, and exhaust.

After all, the design of this engine is too difficult and the technical content is too high. Lin Feng plans to draw more drawings by himself, and will continue to draw design drawings of some key components in the future.

Design drawings of key parts such as fan blades, fan discs, annular flame tubes, turbine blades, etc.

Now that several general design drawings have been drawn, Lin Feng feels that it is almost done for the time being, and the design work can start.

Although Lin Feng stayed in his office most of the time these days, he had heard about the movement of Leihuo Aero-Engine Design Institute.

Almost most of the designers are eager to try it, and some even talk about the design of this engine in their spare time.

"The design work should start!"

"Suddenly I feel very excited. What we will start designing is actually the world's top turbofan engine."

"I heard that it is still the same as the Lh1500 turboshaft engine. Mr. Lin will personally guide us in the specific design work."

"Great, with Mr. Lin's guidance, I think the whole design process should be very smooth."

"It never occurred to me that Mr. Lin's technical attainments in the design of turbofan engines are so high."

"..."

Just as many designers were eager to try, and even hotly discussed the upcoming design work, Leihuo Aero Engine Design Institute finally made a move.

The design kick-off conference was officially held!

In the huge conference room, there were three or four hundred people sitting.All design experts, design backbones, etc. sit here, including some ordinary designers.

Lin Feng attended this meeting!

Fang Anping officially announced that Leihuo Aviation Engine Design Institute's first small bypass ratio turbofan engine design work was officially launched.

The model engineer of this turbofan engine is not Fang Anping, but Zhang Wei.

Zhang Wei was originally a Russian, half Chinese and half Soviet.

He used to be a design expert of a design bureau in the former Soviet Union, and has very high technical attainments in the field of turbofan engine design.

Now he is a Huaxia person, one of the elite talents poached by the human resources department of Leihuo Technology Industry Group.

In the past two years, the human resources department has recruited many people from the post-disintegration of the Soviet Union, including some design experts, and Zhang Wei is one of them.

Lin Feng officially announced that Zhang Wei will be the model chief engineer of this engine.

As soon as the sound fell, the originally quiet conference room became lively, and humming and low-pitched conversations sounded. Except for a few people who knew it in advance, most people were surprised.

"It's actually Zhang Wei, I never expected it!"

"I always thought that Director Fang would be the chief model engineer."

"Zhang Wei had worked in the Tumansky Design Bureau for more than 20 years, where he was a senior design expert."

"Zhang Wei also has a Soviet name that seems to be Bapuyev."

"..."

Lin Feng seemed to think that everyone's reactions were normal and not surprising. After two or three minutes, he raised his hand and pressed down to calm everyone down.

"I know that everyone is a little surprised. It's because you don't know Zhang Wei's level. I think he is one of the highest-level people in our Leihuo Technology Industrial Group in the design and development of turbofan engines."

"I think it is very appropriate for Zhang Wei to be the chief designer of this engine, and I believe he can lead everyone to complete the design work smoothly."

After Lin Feng finished speaking, Zhang Wei stood up and motioned to everyone, all eyes were on him.

Sure enough, it was not a typical oriental face, but a high nose bridge, blue eyes, and a taller figure, a typical mixed race.

It may be because of the relatively low-key at ordinary times, many designers do not know Zhang Wei. At this time, after seeing Zhang Wei himself, he thought to himself, so this is Zhang Wei.

Zhang Wei walked to the speaking seat, and delivered his inaugural speech loudly into the microphone. In addition to thanking the company and Mr. Lin, it was more about expressing confidence. Please rest assured that under the guidance of Mr. Lin, under his guidance Under the leadership, we will definitely be able to complete this glorious and great design task.

"what!"

"Our Chief Master Zhang's Mandarin is so standard and fluent!"

"I thought he only spoke Russian!"

"..."

Zhang Wei's father is from Huaxia, and he has been called Putonghua since he was a child. He is not only fluent in Russian, but also standard and fluent in Mandarin.

After Zhang Wei's speech, Fang Anping announced that starting today, the design and development of this turbofan engine will be officially launched.

There was warm applause and even cheers from the young designers in the conference room.

After the meeting room gradually quieted down, Fang Anping said, "All the experts who participated in the meeting, the key designers, the middle and high-level staff in the institute, etc., go to meeting room No. [-]."

Conference room No. [-] is smaller, more suitable for a meeting of more than a hundred people, but this conference room is too big now.

There is no need for ordinary designers to participate in the next meeting, because they will still play the role of tool people in the next design and development process.

It is these design experts, design backbones and others who really play a role. Before the design and development work is fully launched, it is necessary for Lin Feng to tell you the specific design of this engine.

In conference room number three.

More than a hundred people almost filled the place, Fang Anping said, "Everyone, next, Mr. Lin will explain the specific design of this engine."

There was warm applause!
Many people were extremely excited, especially those who had experienced the design and development of the LH1500 turboshaft engine, and thought in their hearts, sure enough, sure enough!
That's it!

They will also be full of confidence in their hearts. With Mr. Lin's guidance, everyone has full confidence in designing and developing this engine.

After Lin Feng gave a little signal, Fang Anping and Zhang Wei hung up the general design drawing of the engine, a total of three design drawings, and nailed them to the wall with thumbtacks.

"Wow, this is the master plan!"

"It's probably drawn by Mr. Lin himself!"

"Even the overall design drawing has come out!!!"

"..."

There was a slight commotion among everyone, Lin Feng raised his hand and pressed down, the meeting room fell silent, and everyone looked at Lin Feng with a little excitement.

At this moment, everyone can't wait to hear Mr. Lin explain the specific design of this engine.

With a loud voice, Lin Feng first described the specific design parameters and main performance of this engine in general.

Then I started to talk about the design features of this engine in detail, including the advanced designs it adopts...

From the simple to the deep, I talked for more than two hours until 12:30 noon. During the period, there were many slides, which were full of pictures and texts!
Everyone is an expert. After the window paper was pierced, everything is fine, and everyone is more confident.

Everyone recorded at least a dozen pages of notes alone, and some even took more than [-] pages of notes, including some design sketches drawn in notebooks.

Lin Feng said, "Due to the constraints of time, I will stop here today. Starting tomorrow, for several days in the future, I will further explain the design of this engine to everyone."

Next, Lin Feng was very busy and kept his word.Take half a day every day to talk to everyone about the specific design of this engine.

For half a day, Lin Feng mainly focused on drawing design drawings, because CAD is very easy to use, and the drawing efficiency is very high. One after another, design drawings of key components were drawn by Lin Feng.

Others draw design drawings with serious thinking, repeated calculations, alterations, and even pushing to start over. These do not exist here for Lin Feng. He just needs to select some of the more important design drawings in his mind and draw them out.

In this way, the efficiency is very high, and it is also very productive!
Design drawings were drawn one by one, coupled with daily explanations and guidance, the design and development work was carried out smoothly and comprehensively.

Hundreds of tool workers from Leihuo Aviation Engine Design Institute also began to play a role, and began to draw some simple design drawings.

"Honey, are you tired?"

After returning from get off work, as soon as Lin Feng got home, Hu Xiaoxiao thoughtfully pressed his neck and shoulders for him.

Today, the treatment has been upgraded, and the whole body is pressed directly. Although the technique is not very professional, Lin Feng feels very comfortable.

"Fortunately, it doesn't matter how tired I am. After you press it like this, all my fatigue is gone."

"Really, then I will give you a press every day."

Lin Feng lay on the bed, relaxed all over, enjoying Hu Xiaoxiao's pressure, so comfortable that he almost took off directly.

……

Zhu Zhiwen and his party still arrived in Fenghuang City, but instead of directly going to Leihuo Technology Industrial Group, they went to Fenghuang Factory first.

He has never dealt with Lin Feng, but he has a good relationship with Sun Jiangbo and Zhong Zimin from Phoenix Factory, and he has been a personal friend with Suo Jiangbo for more than ten years.

in the office.

Sun Jiangbo and Zhu Zhiwen were drinking tea while chatting about some topics related to this light fighter.

This is a multi-functional, multi-purpose, all-weather third-generation fighter with a single-engine design, and it will be one of our main fighters in the future.

"Old Zhu, your design progress should be pretty good."

"Overall, it's still very good, but there is one thing that worries me."

"Oh, what is it, can you talk to me?"

Zhu Zhiwen sighed softly. He was still relaxed and smiling just now. When this matter was mentioned, he seemed to be in a bad mood.

"In the end, it's still about the engine."

Hearing this, Sun Jiangbo's expression became more serious. As an industry insider, the Phoenix Factory is also engaged in engine manufacturing, and he understands the importance of an engine to this fighter plane.

Sun Jiangbo comforted, "Old Zhu, look forward to everything, and everything will be fine."

Zhu Zhiwen sighed again, and said helplessly, "That's the only way. The design and development cannot be stopped. The higher authorities attach great importance to this fighter plane and look forward to it."

Sun Jiangbo said with concern, "Then what are you going to do?"

"What else can we do?" Zhu Zhiwen said, "Try to keep in touch with Lao Maozi, and try to get them to sell us more engines."

"Well, that's really the only way to go." Sun Jiangbo nodded.

Zhu Zhiwen said hopefully, "If we have a suitable engine in our country, that would be great!"

Sun Jiangbo shook his head gently, "It's too difficult. Take our factory as an example. It is known as the cradle of small and medium aero engines, but there is no turbofan engine that can be sold."

"Only two years ago, I began to map and imitate Lao Maozi's turbofan engine, which will be used as the power of advanced trainers in the future."

Zhu Zhiwen knew about this turbofan engine, and it was at the second-rate level in the world. It was not an advanced turbofan engine. Its thrust was too small, and its thrust-to-weight ratio was only 6.2. It could not be used as the power of this fighter.

After the two chatted for a while, Sun Jiangbo asked, "Old Zhu, the task of designing and developing this fighter plane is very heavy. You should be very busy. Why did you come to us all of a sudden?"

Zhu Zhiwen sighed again, "I can't help it, I don't want to run around, I just want to calm down and lead everyone to design and develop."

"But, the engine thing is like a bone stuck in our throat, it's very uncomfortable."

"I came here this time mainly because I heard that Leihuo Technology Industry Group is planning to develop a turbofan engine, so I came here to take a look."

...............

Today I can only update [-] words, and it is estimated that tomorrow will only be [-]. The day after tomorrow, I should be able to resume regular [-] updates. I have been visiting relatives these days, and the time for coding is really limited.
