Technical analysis, seeking to revitalize China’s science and technology

Chapter 2 F-16 Appearance Design Drawing

Li Youchen looked puzzled, not very proficient in how to use this technology to analyze the panel.

How to obtain the source of knowledge now?
Your sister!Without detailed explanation, how can I collect this source of knowledge?

Looking at the simple structure diagram, suddenly, I got a reminder that the source point plus [-].

"add?"

Li Youchen continued to read the contents of the book, reading it carefully in his eyes.

+0.5+0.5……

By the time he read the entire book, he had gained less than 5.00% of the knowledge source points.

It’s so slow, I have to continue reading to get the source of knowledge.

Looking at the entire book area, there are neatly arranged books on the bookshelves.

Li Youchen's eyes lit up and he was secretly happy:

Enough to read that the analysis is complete...

Although the idea was good, the progress of technical analysis meant that Li Youchen had to read several books in a few hours and could not continue to push forward.

The knowledge source points obtained are less than 30.00%.

"Principles of Missile Development and Application", "Conception and Technology of Second-Generation Fighters", etc. You can remember all the books you need to read at a glance, and it is easy to memorize them with a photographic memory.

The problem for Li Youchen is... there are no new books to read.

This will cause the technical analysis progress to get stuck halfway.

That's it for now, go back and have a good rest.

At least draw the outline design drawing of the F-16, so that when you hand in your homework, you won't be scolded by Zhao.

……

In the evening, the boys' dormitory.

After dinner, Li Youchen lay on the bed and sighed at these appearance design drawings:
The writing power is not very good and some of the curves are awkward.

I have to hand in my homework tomorrow. It should be fine, right?

Just submit one drawing and that's it, the drawn diagram of the fighter plane.

Early the next morning, Teacher Zhao Hong gave a theory class in the morning.

"The F-16 fighter is a third-generation semi-fighter. Its performance is close to that of the fourth generation. Compared with the third generation, part of its fourth-generation technology includes the addition of fly-by-wire flight control. The flight control is due to the fly-by-wire control system. , more convenient, and the previous mechanical operation was completely eliminated.”

"Let me ask you, what is the difference between the fly-by-wire operation of a fighter jet and the original mechanical control?"

Zhao Hong looked around and looked at a classmate, Li Youchen:

"That classmate, please answer."

Li Youchen looked at Zhao Bapi pointing at him and looking at the eyes of the classmates around him. He felt embarrassed and had no choice but to insist on answering by himself.

"Returning to the teacher, the difference between the fly-by-wire operating system and the mechanical control is that one of the transmission is rapid and the other is delayed. Mechanical control, which controls the operation of the elevator, tail and turbojet engine, is slow. Yingjiang was in the F-16 No. On the basis of the third-generation fighter, a fly-by-wire control system is added to replace the mechanical control, just to make it more convenient and better to control the F-16 fighter."

"In the face of the development of modern fighters, backward operating devices will not be valued by Yingjiang. The fly-by-wire flight control developed by others is focused on the pursuit of advanced fighters."

Li Youchen remained unchanged and told the contents of the knowledge textbook.

"Yes. The purpose of fly-by-wire flight control is to quickly transmit operating signals to the wings of the fuselage, tail, turbojet engines, etc., in less than one-half of a second. Within [-] seconds, there is less than a gasp. The operation signal is transmitted to the operator, which is incomparable with bulky mechanical control devices."

"The classmate just now also said that Yingjiang does not value mechanical control devices. It is because of the pursuit of advancement that he abandoned the mechanical controls used on third-generation fighters and switched to a fly-by-wire control system for convenience. "

Zhao Hong looked at the time on his watch, clapped his hands, applauded a few times, and paused the lecture:
"Okay, hand in all the homework I assigned yesterday. No matter how you draw it? You must hand in the outline drawing of the F-16."

"Now, turn in your homework!"

Most of the dozens of college students have a headache because they have to do homework so soon.

"What should I do? I'm not even halfway through the drawing."

"Me too, the curved lines are too difficult to draw. When I drew the outline of the F-16 fighter plane, I haven't reached the tail yet."

"Stop chatting, write your names and hand in your homework."

The monitor is responsible for collecting homework and urging them.

"Yes……"

Several male students sighed and handed in all their unfinished homework.

When he arrived at Li Youchen's place, he quickly handed over the outline design drawing he drew yesterday.The monitor put Li Youchen's design drawings together with other people's homework, took a casual look at them, and handed everyone's homework to Teacher Zhao Hong for review!

Zhao Hong picked up a few outline drawings at random, glanced at them and shook his head with a sigh:
"You guys! No one is serious about painting, and no one has good painting skills."

When it comes to this, most people are very embarrassed by the training.

"Okay, get out of class is over."

Zhao Hong took everyone's homework and went back to review and grade it.

After class, the atmosphere finally relaxed.

Xiao Chen lay on the table, as if paralyzed, "I'm afraid I will be scolded by Zhao Papi. The painting is so rough, and it will definitely be thought that the painting is some kind of crooked melon and cracked jujube."

Seeing that he was disappointed, Li Youchen crossed his arms and looked up at the ceiling:
"It shouldn't be that bad. If it's bad, it will just be slapped with a board."

Xiao Chen saw the sarcastic words he said, "Damn it! It's okay to be beaten by other teachers, but it's scary to think about being beaten by Zhao Papi."

"Other teachers will restrain their strength, but Zhao Bapi has never been able to."

Zhao Hong has the title of "Skin Picker".

It's entirely because of his strictness as a teacher that he won't indulge anyone's enjoyment too much. He uses his teaching methods to educate his classmates.

Sometimes, the homework assigned by him must be completed, otherwise it will be slapped on the palm of the hand.

Because of his strict teachings, many people are afraid of Zhao Hong.

teacher's office.There are no courses for him now, so Zhao Hong has no choice but to complete the homework as soon as possible.

However, seeing these rough paintings, it is not difficult to understand how bad the painters of these students admitted to the Polytechnic University are.

After approving one picture after another, when Zhao Hong got Li Youchen's drawings, he was stunned after taking a glance at them. He looked at them again with his intense and serious eyes:

F-16 appearance design drawing! ?

From the chart, I have never seen such a complete line as a curve.

Li Youchen?
Seeing this name, Zhao Hong thought that it was handed in by the classmate who answered the question in class.

Take out the photos of F-16 fighter jets and compare them carefully with the diagrams painted by Li Youchen.

In contrast, Zhao Hong exclaimed:
"Exactly the same!"

Although the appearance design drawing is not difficult to draw, such a complete fighter plane diagram involves one concept:
Stealth design.

When it comes to such a concept, it shows that the details are handled very well.

But how could a sophomore do that?
Could it be a spy? !

Probably not. How could a spy go to the Polytechnic University?

Go find it and ask him.

Putting down the homework review, Zhao Hong immediately got up and went to find Li Youchen.

10 minutes later……

dorm room.

"Not here? Where did you go?"

Zhao Hong asked.

Several classmates who lived in the same dormitory, Xiao Chen came over and told:

"I should have gone to the library. I heard they were borrowing books."

Zhao Hong thought: "Library?"

Without further ado, Zhao Hong immediately went to the library.

At the same time, on the second floor of the library.

"40.00%, this..."

The books are almost finished and I am not over fifty yet.

Li Youchen really doesn’t know what to do?It took only two days to read two bookshelves of books. The analysis of the core technology of the F-16 fighter jet was too slow.

And I read too many books, which makes me a little dizzy.

The source of knowledge is really difficult to collect.

What's more, you can't read a book repeatedly, and the source of knowledge cannot be collected through a book repeatedly.

F-16 fighter aircraft appearance design drawing, Li Youchen carefully flipped through the drawing design.

Found something wrong.

Wing, angle 35, this is a stealth design in angle.

However, the F-16 fighter jet did not have a stealth design. It was not until the emergence of the fourth-generation fighter jets that researchers developing the fourth-generation fighter jets came up with the concept of stealth design.

Is the appearance design drawing I got a fourth-generation stealth fighter design drawing?
So, Teacher Zhao Hong’s place...

"Li Youchen! Finally found you."

There was a voice coming from the side, and Li Youchen turned around and saw that it was Zhao Papi!
No, isn't he busy?
Why did you come here suddenly?
"Hello teacher."

Li Youchen said hello.

Zhao Hong walked quickly, took out the chart, and asked seriously:
"Li Youchen, tell the teacher, did you draw this picture seriously?"

Seeing Zhao Papi holding his homework, Li Youchen hesitated for a moment and nodded:
"I drew it."

Zhao Hong seemed to be in shock, "It's true!"

Looking at the drawing in his hand, Zhao Hong subconsciously reached out and took it!
Li Youchen was caught off guard, "Teacher, that's..."

Seeing this, Zhao Hong was surprised again and looked up at the sophomore student:
"Follow me to my dormitory."

Holding his wrist, Zhao Hong immediately took him to the dormitory to talk.

……

Teacher's dormitory, single bedroom where Zhao Hong lives.

Putting down four F-16 fighter plane design drawings, Zhao Hong brought him in, closed the door immediately, turned around, and asked in a low voice seriously:

"Tell me. Who are you? You actually have Yingjiang's F-16 design drawings!"

"Also know about the stealth design."

Li Youchen crossed his arms and said, "I'm not."

Zhao Hong questioned: "No? Why do you know the concept of design?! ​​You also know the wings and the stealth design at an angle of 35°."

Li Youchen defended again: "Is this an accidental discovery or an angle problem discovered through photos of F-16 fighter planes? I am not a thief."

Zhao Hong heard what he said and compared the photos and appearance design drawings again.

It is indeed quite similar. If it is innovative, it can touch the threshold of stealth design.

"It's okay if it's not you. If it's really you, it won't be easy to deal with."

"Follow me from now on. If you want to learn more about fighter design, I can help you. If you don't have it, I'll let you have it as much as possible."

Zhao Hong extended an olive branch to him, hoping that he would study hard with him and even become a qualified researcher focusing on fighter aircraft design in the future.
