Chapter 7 Drawing Parts Diagram

Back in the library, Chen Nian was still sitting in his original seat, but this time he did not continue to read the detailed explanation of the gas turbine engine, but spread out the blank paper and began to try to draw the component diagram of the body shape.

An aircraft is composed of thousands of parts, and the parts of the body part are actually the least, mainly structural parts, including spars, frames, ribs and panels, etc.

However, when it comes to the F-22 to be precise, the situation is different again.

The design of a stealth fighter is much more complicated than that of a civil airliner, and most of this complexity is reflected in the body configuration.

Whether it is the connection process or the overall layout, the components of the F-22 are very different from commercial aircraft and even other fighter jets.

What Chen Nian has to do is to reflect these differences on his component drawings.

The first thing he started to attack was the Garrett air intake that Chen Guo mentioned before—or, it was a small part of the Garrett air intake as a whole, the boundary layer adsorption device.

The structure of this device is not complicated, and the technical difficulty is not high, so it is most suitable for official experimental production.

According to the information in his mind, Chen Nian began to draw a picture on the paper stroke by stroke. Just as he was gradually immersed in it, a deliberately lowered voice suddenly came from his ear.

"Student, did you draw the structure wrong?"

Chen Nian raised his head and saw that at some point, a man and a woman were already standing beside him. Among them, the girl was the one who said she wanted to ask him about learning methods, and the boy was the first time he had met.

They watched with great interest the gradually forming blueprints on the table, and it seemed that there was definitely something wrong, so the boy pointed it out.

Chen Nian did not refute immediately, but checked the information in his mind again before replying:

"No, there's nothing wrong with the drawing, that's how it is."

"Ah? How could you be right? The size of your structural skeleton is obviously wrong, and the thickness of the inner wall of the intake pipe is also exceeded."

"Also, the riveting design used for the connecting parts is also beyond the standard. I am a construction machinery major. I have seen the design of this device before, and I am a little interested."

Speaking of this, the boy's face revealed a look of pride. It is estimated that in his opinion, this is the live broadcast of "pretending to hit the field of expertise".

The girl beside her also nodded and added:
"Whether it's for commercial or industrial use, the adsorber is not designed like this-unless you are for a special purpose."

"Are you also a mechanical major?"

Chen Nian asked back with a smile.

"Yes, you're from an aircraft, right? Eh? Wait, isn't this what you drew for an aircraft?"

The girl realized in an instant that she was reading a book about turbine engines during the day, so she must be majoring in aircraft design, and the paintings must be related to aircraft.

If I see something wrong, maybe it is reasonable to put it on the plane?
"Yes, this is the air intake boundary layer adsorption device of a stealth fighter, not an air purifier or an air intake adsorption device of a car."

As soon as these words were spoken, a somewhat embarrassed look appeared on the boy's face.

It's over, this is really pretending to hit the field of expertise.

It's just that the person who was slapped in the face was himself.

But he was not annoyed, he just smiled and apologized:

"Sorry, I'm preconceived. But your drawing is really awesome, the lines are just right, and you have a solid foundation. Are you a graduate student?"

"No, freshman."

"Freshman painting?? Are all the teachers in your college crazy?"

A man and a woman were shocked. In their impression, they seemed to have only started doing such complicated drawings in their junior year.
"It's not freshman painting, it's freshman Chen Nian painting. We don't need to paint."

Li Xiang on the side interjected, and then continued:

"You can't look at him from the perspective of a normal student. This guy is abnormal—no, I mean, he learns so fast that he is abnormal."

The girl nodded approvingly, she had seen Chen Nian's learning method with her own eyes.

Learning in that way is not only a major challenge to the brain, but also a severe test of willpower.

After all, the design of textbooks is very scientific now. After you finish a chapter, you can experience the sense of acquisition of this chapter, which will motivate you to continue learning.

But if Chen Nian's method is followed, the harvest time will be far away.

But of course, there are benefits to this approach as well.

That is, his foundation will be more solid than anyone else.

As long as you are willing to spend time, the ultimate height that can be achieved by learning this way is actually far beyond what can be compared with superficial methods.

"The current students are really amazing. When I was a freshman, I was thinking about how to fall in love all day long, but I still don't have a girlfriend."

"By the way, my name is Qiao He, and this is my older sister, Qiao Mai."

Qiao He's attitude is sincere, he really wants to get to know Chen Nian.

Before hearing his sister say that there was a strange man in the library, he became curious, but now that he came to see him, this man was awesome beyond his imagination.

As a freshman, it is very strong to be able to draw independently. What is even more outrageous is that he said that he drew parts of stealth fighters.

Are there any stealth fighter jets in China?
Even if there is relevant technology, it is not accessible to freshmen, at most he can see a little bit from the public information.

Just relying on a few clues, you can reason about the structural design of certain components by yourself. Not to mention whether it is right or wrong, this idea is already very advanced.

Make friends, and it is estimated that we can help each other in the future.

".Your family name is random enough. My name is Chen Nian."

"The older generation took it. You know, they have a kind of obsession with food. If you have any questions in the future, you can ask me—you can also ask her. She is still very good at mechanical manufacturing."

Chen Nian nodded with a smile, and after a few words of politeness, he returned to the drawing work.

Qiao He and Qiao Mai looked at it for a while, and then went about their own business. Only Li Xiang did nothing and followed Chen Nian to draw.

Chen Nian draws a stroke, so does he.

Chen Nian didn't pay much attention to his actions.

He knew that Li Xiang didn't want to plagiarize, but just wanted to see if he could keep up with him.

Otherwise, he should have copied it as early as when drawing the F-22.

However, although Li Xiang seemed to be a 100% replica, after three hours, the final blueprints presented by the two were still very different.

"Damn it. It's so difficult."

"I thought I could just follow you to paint, but I didn't expect that this stuff is not like that at all."

Chen Nian glanced at the drawings in Li Xiang's hands curiously, and shook his head involuntarily.

It was horrible.

The proportions are wrong, and the line arrangement is also very messy.

"Practice slowly, this is not a day's work"

"How can you draw so well?"

Chen Nian smiled and didn't answer, thinking that the first day when he was in the drawing class, the things drawn were not even seen by dogs. To be able to do what he is doing now is not a day-by-day practice.

There is no shortcut to the accumulation of knowledge and skills.

This point is the same as the system requirements.

Only new knowledge can bring the source.

I spent three hours drawing. Although this process can be regarded as a kind of learning, it uses all the information already in my mind, so I didn’t add any sources.

However, Chen Nian couldn't give up this job because of this. After all, it was useless to keep things in his mind, he had to present them and show them to others.

And according to Chen Guo's plan, tomorrow is the time to show
