Chapter 10 Lectures

"Hey, classmate Chen Nian, don't mind your previous attitude, I'm also here for work! You know, it's not a good situation right now, there are too many bad guys......."

"By the way, look at me, I forgot to introduce myself."

"My name is Lei Gang, I am an engineer of the 601 Institute, and I am also an old astronaut, you can just call me Lao Lei!"

After basically confirming the authenticity of the component diagram, the tone of the man who first opened his mouth to question Chen Nian also changed drastically.

Of course, his original tone was originally pretended, and Chen Nian guessed it at the beginning.

What kind of screws and the like are just a pretext for deliberately beating him.

What screws do you need for wind tunnel experiments? Make up a shell and blow it up, and you're done!

But he didn't blame the other party at all, because this era was not like the 20s of the 21st century that he was familiar with.

What is the best wish on the Internet at this time?

The next life of the United States.

What are your most eagerly awaited expectations?

Another year of looking south at the king's division.

What is the most vicious insult?

Five cents.

In this environment, there's nothing wrong with being cautious.

But thinking of this, Chen Nian's thoughts couldn't help but drift a little farther away.

He thought that many children born after 00 years do not remember this era, because the environment they are in has actually changed a lot.

They have not really experienced or deeply experienced those years of struggle, nor have they understood why the overall atmosphere of a country can become better.

Is this perhaps a fragile pride?

If you want to make this pride strong, you must either break it and reorganize it, or you can add to it with all your might.

There is no doubt that you have to choose the latter.

Thinking of this, Chen Nian retracted his thoughts and replied to Lei Gang with a smile:

"Lei Gong, it's okay, I can understand."

"That's good, that's good, hey, by the way, we can basically understand this filter, there must be no other problems, so the other parts, can you give us a rough description now?"

"Absolutely."

Hearing Chen Nian's answer, many experts present all sat back in their seats.

At this moment, they seem to have returned to their school days.

No one showed embarrassment about this---- they were all extremely pragmatic experts, and they knew that there must be a teacher in the threesome.

"Where to start?"

Chen Nian sat solemnly on the chair and asked.

"Let's talk about the overall configuration of the fuselage first!"

Chen Nian nodded, thought for a moment and said:

"In general, the front fuselage section of the F-22 is a non-standard diamond, the middle fuselage section is pentagonal, and there is a gradual transition to a flat rectangular section of the rear fuselage."

"Viewed from the front, the lower part of the fuselage is inclined inwards about 35 degrees, and there is a ridge from the apex of the nose to the leading edge of the air intake, and this ridge-shaped precursor avoids the main direction of the radar wave threat."

"The F-22 also adopts the edge strip wing vortex lift technology that is also available in the third generation aircraft, the narrow edge strip from the air intake to the wing root and the ridge line of the front fuselage form a side strip extending from the apex of the nose to the wing root, and the front fuselage and the air intake are integrated, which also becomes a lift body, which increases the action area of the edge strip, assists in improving the lift of the main wing surface at small angles of attack, and generates vortices at large angles of attack, so as to obtain stronger vortex lift........"

Chen Nian narrates not only the simple description of shapes, but also the interpretation of design principles.

All the experts present listened fascinated, and to be honest, these things were not very profound, because Chen Nian did not interpret the specific principles and data.

However, even such a generalization presents an extremely clear logic, which undoubtedly proves one point:

He was perfectly familiar with the plane.

Familiar with it, he can use memory to express most of the design intentions in words.

Still, the calculation is a key issue.

So, when Chen Nian stopped to drink water, Lei Gang asked:

"How do you make assumptions about the calculation of the eddy current?"

"I calculate thrust back by eddy current-induced drag, and the F-22 is special in that its wing design reduces the wingtip vortex, but the upper surface vortex becomes more complex, and to calculate this problem, you have to consider aspect ratio, vortex-induced drag, lift and wingtip vortex strength."

"To this end, I found relatively accurate photos, measured the aspect ratio and area of the F-22, assumed a CI value, reasoned the CDi, and then gradually adjusted it, and then got basically logical data."

"It's as simple as that? No, it's not easy, but how do you verify it? ”

Lei Gang asked suspiciously.

"I can't verify it, so how can I say I want to build it?"

“....... Also, what is your criterion for judging whether you are right or not? ”

"Beauty."

"Beauty?"

"Yes, if a weapon is to be powerful and accurate, then it must first be beautiful."

"It has to conform to all human aesthetics of a weapon, it has to have smooth curves, sharp edges, just the right proportions....... It's hard for me to explain it, but maybe I have a unique intuition about this aesthetic. ”

Daigo empowerment!

Everyone present was shocked by Chen Nian's speech.

It's the first time they've heard it.

If a weapon is strong, it must be beautiful.

It seems absurd, but if you think about it.......

What powerful weapon isn't beautiful??

Is the white swan beautiful? Is the F-22 beautiful? Was the Roosevelt beautiful? Are the ICBMs erected one by one beautiful?

Not only beautiful, but even shockingly beautiful.

Of course, many people can't experience this kind of beauty, but what they can experience must be to have a natural intuition.

For a while, the same thought came to everyone's minds:

This Chen Nian belongs to me! Never let anyone else snatch it!

And just opposite them, Chen Nian looked at the people who were shocked, and couldn't help but feel a little funny in his heart.

He remembered that the concept that weapons are beautiful was put forward and carried forward by the man who called it the strongest strategic weapon, as if after that, Huaxia's weapons and equipment really became better.

Now that I have copied his views in advance to explain myself, I may be able to help these engineering men improve their aesthetics in advance.......

"I see....... Thinking intuitively is indeed a very feasible method in research, but it must be verified. ”

"Let's talk about the specific parts, we need to build this thing quickly!"

Looking at Lei Gang's impatient expression, Chen Nian smiled and replied:

"This problem is not so easy to explain, so I'll pick this adsorption device that you have a picture in your hand and talk about it."

"For other specific designs, please give me a little more time, I have to organize my thoughts, and I have to take it out of my head step by step......."
