Back in the library, Chen Nian was still sitting in his original position, 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 shape of the body.

An airplane is made up of thousands of parts, and the fuselage part is actually the least part, mainly structural parts, including spars, frames, ribs, and siding.

However, to be precise with the F-22, the situation is different again.

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

Whether it is the joining process or the overall layout, the composition of the parts of the F-22 is very different from that of commercial aircraft and even other fighter jets.

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

The first thing he started to do was the Galette inlet mentioned by Chen Guo before---- or a small part in the whole of the Galette intake, the boundary layer adsorption device.

This device generally uses hydrocarbon as adsorbent material, including air filter and air pipe, connecting skeleton, adsorption filter paper, etc.

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

According to the information in his mind, Chen Nian began to draw on the paper one by one, and just as he was gradually immersed in it, a deliberately suppressed voice suddenly came from his ears.

"Classmate, you drew the wrong structure of the filter element, right?"

Chen Nian raised his head and looked, at some point, there were already two men and a woman standing beside him, among which the girl was the one who said before that he wanted to ask him for learning methods, and the boy was the first time he saw him.

They looked at the drawings on the table with great interest, and it seemed that there was absolutely something wrong, so the boy pointed out.

Chen Nian didn't refute it immediately, but checked the information in his mind again before replying:

"No, that's right, that's it."

"Huh? How could it be right....... The size of your structural skeleton is obviously wrong, and the thickness of the inner wall of the air intake pipe is also excessive. ”

"Also, the riveting design used in the connector is also out of standard, I am a construction machinery professional, and the design of this air purifier happens to have been seen before, so I am a little interested."

Speaking of this, the boy's face showed a look of pride, and it is estimated that in his opinion, this is the live broadcast of "pretending to be forced to hit the field of expertise".

And the girl next to her also nodded, adding:

"Filters aren't designed that way, whether it's commercial or industrial---- unless you're special."

"You're also a mechanical major?"

Chen Nian smiled and asked.

"Yes, you're a flying machine, right? Ay? Wait, this isn't going to be used on airplanes, is it? ”

The girl reacted instantly, people read the book on turbine engines during the day, it must be a major in aircraft design, and the thing drawn must also be related to airplanes.

If you look at something wrong, maybe it makes sense to put it on the plane?

"Yes, this is the air inlet filter of a stealth fighter, not an air purifier."

As soon as he said this, a slightly embarrassed look appeared on the boy's face.

It's over, it's really pretending to collide with what you're good at.

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

But he wasn't annoyed, he just smiled and apologized:

"I'm sorry, I had a preconceived idea....... But your drawings are really awesome, the lines are just right, and you have a foundation. Is it a graduate student? ”

"No, freshman."

"Freshman draw this thing?? Are the teachers at your academy crazy? ”

A man and a woman were shocked, and in their impressions, they seemed to have started to do complex mapping like this in their junior year.......

"It's not the freshman who painted this thing, it's the freshman Chen Nian who painted this thing. We don't have 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 not normal---- no, I mean, he learns so fast that it is abnormal."

The girl nodded thoughtfully, 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, textbooks are now scientifically designed, and when you finish a chapter, you can experience the sense of accomplishment of that chapter, which will motivate you to keep 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.

That is, his foundation will be stronger than anyone else's.

As long as you are willing to take the time, the ultimate height that can be achieved by such learning is far from being comparable to the superficial way.

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

"By the way, my name is Qiao He, and this is my old sister next to me, Qiao Mai."

Qiao He's attitude was sincere, he really wanted to get to know Chen Nian.

Before, he was curious when he heard his old sister say that there was a strange person in the library, but now when I come to see, this person is beyond his imagination.

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

Are there stealth fighters in the country?

Even if there is relevant technology, it is not something that a freshman can access, and he can only see a little bit from the public information.

Relying on a clue of a star, you can deduce the structural design of some parts by yourself, and this idea is already very advanced, not to say whether it is right or not.

Make friends and make friends, and I guess we can help each other in the future.

“...... The name of your house is arbitrary. My name is Chen Nian. ”

"The older generation took it, you know, and had an obsession with food....... If you have any questions in the future---- you can ask me, she can also ask her, she is still very good at mechanical manufacturing. ”

Chen Nian nodded with a smile, and after a few polite sentences, he devoted himself to the work of drawing again.

Qiao He and Qiao Mai looked at each other for a while, and they also went to do their own things, only Li Xiang didn't do anything, just followed Chen Nian on the side to make pictures.

Chen Nian paints a stroke, and he also paints a stroke.

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

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

Otherwise, he would have copied the F-22 long ago.

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

"Damn....... It's so hard. ”

"I thought I would be able to draw with you, but I didn't expect this thing to be like that at all."

Chen Nian curiously glanced at the drawings in Li Xiang's hand and couldn't help but shake his head.

It's terrible.

The proportions are not right, and the lines are messy.

"Practice slowly, it's not a day's work......."

"How can you draw so well?"

Chen Nian smiled and didn't answer, thinking that on the first day of his drawing class, the things he drew were not even looked at by dogs, and he was able to do it like this, and it was not a day-to-day practice.

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

This is the same as the requirements of the system.

Only new knowledge can bring the source point.

I spent three hours making the drawing, and although this process is also a kind of learning, it uses the information that I already have in my head, so I don't actually add any source points.

However, Chen Nian can't give up this job because of this, after all, it's useless to keep things in his head, he must present them and show them to others.

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