Chapter 160 Draw the design drawings by yourself

The design institute has a total of six design rooms, and six design room directors, four of them are sitting together now, talking about the design of the LH1500 turboshaft engine.

Single rated output power 1526KW
The total weight of the engine is 296KG
Compression ratio 21.2
Lifespan of 4000 hours in the first turning period
Such a high starting point puts a lot of pressure on everyone.

Wang Gang, the director of the overall design office, said, "Everyone, it seems that we have to make enough mental preparations. What we are facing will be a road full of thorns."

Wang Jianshu, director of the third design office, said: "Such a turboshaft engine is absolutely world-class. This is a huge challenge for us."

Hua Jingsheng said, "Although the pressure is huge, I believe the boss has a reason for setting such a high starting point."

"This design technical outline was written by the boss himself. I think he should have a certain degree of confidence. Let's follow the boss and work hard."

"."

Several office directors were chatting like this, when Lin Feng opened the door and came in, he said with a smile, "It's so lively, what are you talking about?"

"Hi boss."

"Boss, we are talking about the design of the LH1500 turboshaft engine."

Originally we were talking about the design, Lin Feng said, "For the design of the LH1500 turboshaft engine, I will guide you to carry out the specific design, the general design drawing, and the design of some key parts, and I will personally draw the design drawing."

what!
Boss, are you so good?
Everyone was surprised. They originally thought that the boss was just the boss, who would at most solve the funding problems needed for design and development, as well as some daily management. How could they know that the boss would draw the design drawings himself.

"Really!"

"Boss, I'm really looking forward to drawing the design drawings yourself."

Lin Feng said: "Let's look forward to it. You will see the design drawings I drew in two days. I am currently drawing the general design drawing of the compressor unit."

The LH1500 turboshaft engine adopts a unit body design.

The so-called "unit body" means that this part is relatively independent and interchangeable with other parts.For example, the compressor part is a unit body. Once the compressor of the engine fails, the unit body can be disassembled directly, or even installed with another compressor unit body, and then the engine can be used and worked normally.

Lin Feng had already figured it out, and drew out the general design of each unit body, as well as several important and key parts of each unit body.

Such as compressor unit body.

Lin Feng is going to draw the general design drawing of the compressor unit by himself, as well as design drawings of the first and second overall axial flow impellers, centrifugal impeller design drawings and other design drawings.

These drawings were drawn by Lin Feng himself, so the design of the entire compressor unit was much simpler, and the difficulty of the design plummeted. Zhang Xu from the compressor design office and his design team should be able to complete other designs of the compressor unit.

In addition, in addition to personally drawing some design drawings, during the design process, Lin Feng will also provide design guidance, so that the design drawings drawn by everyone are consistent with the design drawings provided by the system.

Lin Feng left after chatting with everyone, but the four office directors were not calm anymore.

"Did I hear it wrong."

"That's right, the boss said it himself. The general design drawings of each unit, and several key and important parts of each unit are all designed by the boss himself."

"In this way, the design difficulty is greatly reduced, and I am full of confidence in the future design."

"Just now I was full of pressure and felt that this was an unprecedented challenge, but now I have a little expectation to start the design earlier and design our LH1500 turboshaft engine earlier."

"."

The mental outlooks of the four office directors are different. Everyone's brows are completely stretched out, and their faces are full of confidence.

As for Lin Feng, he returned to his office.

In this renovated design building, Lin Feng also has his own office, which is fully equipped with office equipment, such as large desks, office chairs, bookshelves, coffee tables, sofas, etc., as well.

In addition to such an office, there is a reception room and a drawing room next to it.

In the center of the drawing room, there is a large table with a drawing board, a T-square, a compass, a set square, etc., as well as a lot of pencils, a few erasers and a pencil sharpener.

Lin Feng looked at it with satisfaction, and then picked up a knife and a pencil to sharpen. After a while, all the pencils were sharpened.

Now there is no computer drawing, everything is purely manual, and the drawing of any design drawing starts with sharpening a pencil.

After pinning the pencil, Lin Feng spread out a No. 1 blank drawing on the drawing board, and then began to seriously draw the general design drawing of the compressor unit.

There is a ready-made general design drawing of the compressor unit in his mind, what Lin Feng has to do is to draw it on this No. 1 white paper.

You don’t need to use your brain to think, let alone calculate, and the speed is much faster. I started drawing in the morning, and by three or four o’clock in the afternoon, the general design drawing was basically completed, leaving only some technical conditions that were not marked .

Lin Feng is holding a pencil and writing technical instructions in standard imitation Song characters.

While writing, Lin Feng thought in his heart, this kind of drawing is really not ordinary cool, the general design drawing of this compressor unit has been drawn so quickly, if there is no ready-made design drawing provided by the system, it is estimated that It took ten days and half a month to complete this design drawing.

At 04:30 in the afternoon, the general design drawing of the compressor unit was completed. Lin Feng took a look at it and was very satisfied.

He raised his hand to check the time, and there was still an hour before he got off work, so another design drawing was laid out.

This is a No. 2 design drawing, which is half the size of No. 1 drawing. This blank No. 2 design drawing is going to be used by Lin Feng to draw the first and second overall axial flow impellers.

The axial flow impeller design of the LH1500 turboshaft engine is different from that of the turboshaft eight, and the difference is relatively large.

The axial flow impeller of turboshaft eight is also integral, but only one stage.

The axial flow impeller of the LH1500 turboshaft engine is not only integral, but also has two stages, and its compression ratio is higher.

Similarly, there are ready-made design drawings in his mind, and Lin Feng has fully digested and understood it. Drawing the design drawings of the first and second integral axial flow impellers is simply easy, and the speed is not so fast.

Lin Feng was completely immersed in the drawing of the design blueprints, he completely forgot the time, and it was already dark outside.

There was a knock on the door.

Liu Shunkang pushed the door in and said in surprise, "Boss, you are still drawing design drawings. It's already past seven o'clock in the evening."

Lin Feng put down the pencil in his hand, raised his hand to look at the time, and said with a smile, "Oh, time flies so fast, no wonder I'm a little hungry."

Liu Shunkang said, "Boss, I just haven't eaten yet, how about we go and have some food together?"

Lin Feng said, "Yes, it happens that I have some things to explain to you at work."

After locking the door, the two went downstairs together. At the gate on the first floor, Lin Feng saw two officers on duty and nodded slightly in satisfaction.

With the start of the design and development work, the security here is very important, absolutely no idlers are allowed to enter, needless to say during the day, and there are several people on duty at night.

The two found a restaurant nearby, ordered a few dishes, and chatted while eating.

Lin Feng mainly explained a few points. The first is to continue to recruit design and R&D talents, especially design talents with rich aero-engine design experience and intermediate and senior professional titles.

Second, set up a security team, mainly recruiting veterans, responsible for the security work of the design building.

Liu Shunkang kept them all in mind, and also reported his work to Lin Feng. For example, he had found several good design talents and was in contact with them.General design talent has also been continuously recruiting and so on.

Two days later.

Lin Feng put down the pencil in his hand with satisfaction, and within two to three days, the general design drawing of the compressor unit, the design drawing of the first and second overall axial flow impellers, and the design drawing of the centrifugal impeller, a total of three design drawings, were all completed.

This kind of efficiency is simply leveraged.

Lin Feng sorted out these design drawings, took them out, and went to the second design room.

Lin Feng also thought a lot about drawing the design drawings in such two or three days. He planned to draw the general design drawings of each unit first, and then draw the design drawings of the important and key parts of each unit.

In the next month, Lin Feng will be very busy, because at least there are more than [-] design drawings that he needs to draw himself.

The second design studio.

The [-] or [-] designers don't have many things to do at the moment, that is, to digest and understand the design technical outline. As for the specific design, they have to wait for a while.

Because there are not many things to do, it seems not busy, and many designers are chatting.

"The boss said that he would personally draw part of the design drawings. I don't know if it is true or not."

"I think it's more hanging. If he is so good, he would have been a well-known expert in aero-engine design in China."

"It seems that we have to rely on ourselves for all the design drawings."

"."

Everyone was chatting like this, and they were dubious about the fact that Lin Feng drew the design drawings himself.

At this time, Zhang Xu, the director of the design office, walked in and said loudly, "Put down what you are doing and go to the meeting room immediately."

Each design studio has two or three large offices and at least one meeting room. Under the leadership of Zhang Xu, a group of designers went to their meeting room.

"Boss, everyone is here."

Lin Feng's eyes swept over everyone. There were a total of more than 30 designers, all of whom were relatively young, and half of them were under [-] years old.

The average age of the entire design team is estimated to be less than 35 years old, which means that the design experience is generally insufficient, Lin Feng thought in his heart, fortunately, there is a complete set of design drawings provided by the system.

Otherwise, it would be a dream for such a design team to design and develop such an excellent turboshaft engine.

After Lin Feng looked at everyone, he said loudly, "Starting from today, the design of the compressor unit will be officially launched. Everyone will be busy for a long time, and we need to be prepared for this."

There was a young designer who seemed rather courageous, a typical newborn calf who is not afraid of tigers, and said loudly, "Mr. Lin, I heard that you will personally lead us to design and develop, and even draw some design drawings yourself. Is it true? ah."

This questioned the aspirations of all the designers, and there was a slight commotion in the meeting room.

Lin Feng smiled confidently, and said loudly, "Of course it is true. Without my leadership and guidance, would you have the confidence to design and develop such an excellent turboshaft engine?"

Many designers laughed.

They really don't have this ability.

Lin Feng said, "Under my leadership and guidance, everyone carried out the design according to my requirements. I have already drawn up some design drawings. Now I will tell you about the design of the compressor unit."

After finishing speaking, Zhang Xu made a brief gesture, and immediately pinned the general design drawing of the compressor unit drawn by Lin Feng to the blackboard in the meeting room with thumbtacks, and displayed it in front of everyone.

Lin Feng pointed to the general design drawing and said loudly, "This is the general design drawing of the compressor unit. Let me tell you about its design structure. It consists of the compressor casing, the first and second axial flow impellers, centrifugal impeller etc.

Gradually, many designers could not calm down.

My goodness!

Mr. Lin really drew the general design of the compressor unit, which is too unbelievable.

It looks very well designed!
Zhang Xu was also a little bit excited. Experts looked at the doorway, and laymen watched the fun. He is a senior aero-engine designer and has been engaged in this industry for more than ten years. He can tell at a glance that the design of the compressor unit is very unusual.

He quickly took a deep breath to calm down his heart as much as possible, and sat there listening carefully and taking notes like an ordinary designer.

Combined with the general design drawing of the compressor unit, Lin Feng explained it for at least four or five 10 minutes, and the explanation was very detailed.

Then, the design drawings of the first and second-stage axial flow impellers and centrifugal impellers were hung up, pointing to these design drawings and explaining in detail.

Listening to what you say is better than reading ten years of books.

Many designers have a feeling of enlightenment. At first, the whole design road was full of fog, but now, it is very clear.

After talking for nearly half a day, Lin Feng finally basically finished his speech, and finally said, "You follow what I said, and combine these few design drawings to carry out detailed design."

Zhang Xu said, "Don't worry, the boss, we will definitely complete the design task excellently."

Originally he was very stressed.

Now, where there is still half a point of pressure, the rest is only excitement.

The whole person is also full of ambitions, and he can't wait to start the specific design work of the compressor unit immediately.

After speaking to everyone, Lin Feng returned to his drawing room, spread out a blank design drawing, picked up a pencil, and started drawing design drawings again.

And almost all the designers couldn't calm down, not just the technicians in the second design room.

"The boss is awesome!"

"It's unbelievable, I never thought Mr. Lin would be so powerful!"

"It was a design job done entirely on my own, and what was left for us was already very simple."

"This time, I have opened my eyes!"

All the designers were like this, and several office directors couldn't calm down, and ran to the second design room one by one, looking at the design drawings drawn by Lin Feng with great interest.

On the big table in the reading room, these design drawings were spread out, and several directors gathered together, looking at them with gusto.

Although each person is only responsible for one unit, he is also good at designing other parts.

After looking at it carefully, Wang Gang, the director of the first design office, said with admiration, "Although there is no design verification yet, I think the boss's designs should not be a big problem."

"I think so too. Even if there is a problem with the design verification in the future, a little design modification and improvement will be enough."

"The boss is so good, I have full confidence in the engine we designed."

"I, I can't wait to finish the design as soon as possible, and hope to see the first engine manufactured sooner."

"."

The designers of the second design office are already working on the specific design, and the other design offices are also gearing up and eager to try, wishing to start the design work earlier.

In the drawing room.

Lin Feng is drawing the general design drawing of the combustion chamber unit.Air enters the engine from the outside, first compressed by the axial flow impeller, then compressed by the centrifugal impeller, and then passed by the centrifugal guide vane, and the highly compressed air enters the combustion chamber.

The combustion chamber is a high-temperature component where fuel and air are mixed and burned. The design of this component is not simple, especially involving a series of complex calculations.

Such as the shape of the combustion chamber, the position and size of each cooling hole, the design of the nozzle, etc., are very complicated.

It doesn't exist in Lin Feng's place, as long as he draws the design diagram provided by the system in his mind, a series of complicated calculations don't exist.

Lin Feng's drawing speed is not slow for the annular combustion chamber, with nine nozzles evenly distributed, the inner and outer flame cylinders, the combustion chamber casing, etc.

"Boom, boom, boom!"

There was a knock on the door of the drawing room, and Hua Jingsheng, the director of the fourth design room, pushed the door in full of hope, "Boss, are you drawing the overall design of the turbine unit?"

He couldn't wait for a moment, and hoped to see the general design drawing of the turbine unit earlier, and hoped to start the design work earlier.

"Director Hua, it's you." Lin Feng said.

Hua Jingsheng took a few steps forward full of hope, and finally saw the design drawing on the drawing board, and was immediately a little disappointed.

Lin Feng saw his disappointed expression in his eyes, and said with a smile, "Don't be disappointed, I will start drawing the general design of the turbine unit tomorrow, and you will be able to see the design drawings I drew the day after tomorrow at the latest."

"Really!"

Hua Jingsheng was pleasantly surprised that Lin Feng's efficiency was never so high, and they would be able to see the general design of the turbine unit the day after tomorrow.

Very good!
Hua Jingsheng said a little excitedly, "Boss, then I won't bother you, I'll go out first."

He happily left the drawing room, closed the door gently, and waved his fist excitedly, oh yes!

As soon as he came out, Hua Jingsheng met Wang Jianshu, the director of the third design office in the corridor, and the latter asked, "Director Hua, did you go to the boss just now?"
