"Hey, hey, hey, classmate Chen Nian, don't mind your previous attitude. I am doing this for work! You know, the current situation is not good, there are too many bad elements..."
"By the way, look at me, I forgot to introduce myself."
"My name is Lei Gang. I am an engineer from Institute 601. I am an experienced aerospace expert. You can just call me Lao Lei!"
After basically confirming the authenticity of the component diagram, the tone of the man who first questioned Chen Nian also changed drastically.
Of course, his original tone was an act, and Chen Nian guessed it from the beginning.
Making screws and the like was just an excuse to deliberately beat him.
What screws are needed for wind tunnel testing? Just make a shell and blow it out and that's it!
But he didn't blame the other party at all, because this era was not like the 2020s he was familiar with.
What is the best blessing on the Internet at this time?
America in the next life.
What is your most ardent expectation?
Look south to Wangshi for another year.
What's the most vicious insult?
Fifty cents.
In this environment, there's nothing wrong with being cautious.
But thinking of this, Chen Nian's thoughts couldn't help but wander a little further.
He thought that many children born after 2000 would not remember this era because the environment they lived in had actually improved a lot.
They have never truly experienced or deeply understood those years of struggle, nor have they understood why the overall atmosphere of a country can improve.
Is this perhaps a fragile form of pride?
If you want to strengthen this pride, you must either break it into pieces and reassemble it, or you must add more bricks and stones to it.
There is no doubt that I will 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 understand."
"That's good, that's good. By the way, we can basically understand this filter. There must be no other problems. As for the other parts, can you give us an overview now?"
"No problem at all."
After hearing Chen Nian's answer, many experts present sat back in their seats.
At this moment, they seemed to have returned to their student days.
No one showed embarrassment about this - they were all extremely pragmatic experts, fully aware that in a group of three, there must be one person who can learn from us.
"Where to begin?"
Chen Nian sat on the chair solemnly and asked.
“Let’s talk about the overall configuration of the fuselage first!”
Chen Nian nodded, thought for a moment and said:
"Generally speaking, the F-22's front fuselage section is a non-standard diamond shape, the middle fuselage section is a pentagon, and gradually transitions to a flat rectangular section of the rear fuselage."
"Looking from the front, the lower part of the fuselage is a slope inclined inward at about 35 degrees. There is a ridge from the top of the fuselage to the leading edge of the air inlet. This ridged precursor can avoid the main direction of radar wave threats."
"The F-22 also adopts the edge strip wing vortex lift technology that is also found in third-generation aircraft. The narrow edge strip from the air inlet to the wing root and the ridge line of the front fuselage form a strip extending from the top of the fuselage to the wing root. The front fuselage and the air inlet are integrated and become a lift body, which increases the effective area of the side strips, assists in increasing the lift of the main airfoil at small angles of attack, and generates vortices at large angles of attack, thereby obtaining stronger Vortex lift..."
Chen Nian's eloquent talk is not just a simple description of the shape, but also interspersed with an interpretation of the design principles.
All the experts present were fascinated. To be honest, these things are not very advanced, because Chen Nian did not interpret the specific principles and data.
However, even just such an introduction shows a very clear logic, which undoubtedly proves one point:
He was extremely familiar with the aircraft.
He realized that he could express most of the design intentions in words by relying on his memory.
Still, calculation is the key issue.
So, when Chen Nian stopped to drink water, Lei Gang asked:
"What assumptions did you make for the calculation of airfoil vortices?"
"I calculate reverse thrust through vortex-induced drag. The F-22 is special. Its wing design reduces wingtip vortices, but the upper surface vortices become more complex. To calculate this problem, we must comprehensively consider the development of the thrust. Chord 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, deduced the CDi, and then gradually adjusted it to obtain basically logical data. "
"Is it that simple? No, it's not simple either, but how do you verify it?"
Lei Gang asked doubtfully.
"There's no way to verify it. How else can we say it's going to be created?"
"...Yes, then what is your standard for judging whether it is correct?"
"beautiful."
"beautiful?"
"Yes, if a weapon is to be powerful and accurate, it must first be beautiful."
"It must conform to all human aesthetics for weapons. It must have smooth curves, sharp edges, and just the right proportions... It's hard for me to explain. Maybe, I have a certain understanding of this aesthetic. Unique intuition."
Enlightenment!
Everyone present was shocked by Chen Nian's speech.
It was the first time for them to hear this statement.
If a weapon is powerful, it must be beautiful.
It seems absurd, but think about it carefully...
What powerful weapon is not beautiful? ?
Is the white swan beautiful? Is the F-22 beautiful? Is the Roosevelt beautiful? Are the intercontinental missiles standing upright beautiful?
Not only is it beautiful, it is even stunningly beautiful.
Of course, many people cannot appreciate this kind of beauty, but those who can appreciate it must have a gifted intuition.
For a moment, the same thought came to everyone's mind:
This Chen Nian belongs to me! Never let anyone else take it away!
Opposite them, Chen Nian looked at the shocked people and couldn't help but feel a little funny.
He remembered that the concept of beautiful weapons was proposed and carried forward by the man who was called the most powerful strategic weapon. It seemed that after that, China's weapons and equipment really became more beautiful.
Now that I have plagiarized his views in advance to explain myself, maybe it can be regarded as helping these engineering men improve their aesthetics in advance...
"I understand... Thinking based on intuition is indeed a very feasible method in research, but verification must still be done."
"Let's talk about the specific parts, we have to build this thing quickly!"
Seeing Lei Gang's impatient expression, Chen Nian smiled and replied:
"This question is not so easy to explain. I will just pick the adsorption device you have the picture in and talk about it."
"As for other specific designs, please give me a little more time. I have to organize my thoughts and take them out of my mind step by step..."
