Before returning to the college entrance examination, I became popular in the science circle

Chapter 119 Hope
Wu Tong immediately stood up and confirmed the status of master and apprentice in a respectful voice.

"Congratulations to the old man for getting a good disciple, and congratulations to Wu Tong for meeting a famous teacher!" Lu Xiao and Zheng Hongming applauded with a smile.

Cheng Huanan is an old man, and he is one of the top few in the domestic material circle. Wu Tong is already talented, and learning from such a famous teacher will be unrivaled in the future!

Zheng Hongming jokingly said: "Cheng Lao, I'm going to make a fool of myself today!"

Anyone who receives a good student with such talent as Wu Tong should be happy to celebrate!
"You deserve it, you deserve it, if Wu Tong is willing, I'll be on the side of the material and lead you the way!" Cheng Lao's face was no longer as serious as it used to be, and it could really be called a happy smile at the moment.

There is no regret in this life to have such a good student.On the face that doesn't smile often, there is a big happy smile at this moment. It looks a little funny at first, but who cares!

"I ask you two to help me witness, I can finally welcome the closed disciple!"

He said before that the closed disciples inherited everything from him, and he dedicated his life to the country. Only this body of knowledge is passed on, and he hopes that the students will be better than blue.

He treats every beginner student seriously, but he can basically see the upper limit of these students. As a teacher, who wouldn't want to meet a top student.

Now that I have to meet Wu Tong as a student, I really have no regrets.

No longer feeling that he was getting older, he was gearing up a bit, and he had already started to think about the learning process he wanted to arrange for Wu Tong.

According to his understanding, Wu Tong's learning speed is very fast. Judging from the fact that she was able to make such great achievements at such a young age, what she said is absolutely true. Such an ordinary class is definitely not suitable for her.He has to make a plan for Wu Tong's study, and adjust according to Wu Tong's progress and needs at any time.

"Mr. Cheng, let me first borrow from you, classmate Wu Tong. I have some problems with the F-22 mathematical model. I need to discuss it with Wu Tong!" Lu Xiao and Cheng Huanan reported,

Wu Tong first had a teacher with a good reputation, but it was not comparable to his honorary teacher, who was reluctant to hook up and couldn't beat him.

"Ask, ask, you guys can talk here. I'm going to take a look at the repeated data in the laboratory. Cheng Xu will sort it out and bring it over later!" Cheng Huanan waved his hand, got up and walked out to make some quiet space. The question probably involves confidentiality, so I voluntarily avoided it.

Zheng Hongming followed Mr. Cheng's footsteps, "I'm also going to see how everyone else's confidentiality agreements have been signed!"

"Mr. Lu, what are the specific problems? Let's discuss together!"

After signing various confidentiality agreements just now, Wu Tong also learned about this current responsibility, and was really surprised.In the future, the Veyron J-20 that will make countless Chinese people excited and proud is actually led by this teacher, which is really amazing!

The take-off of the J-20 means that China also has an international standard fourth-generation fighter jet, has the power to regain China's air supremacy, and has the confidence to have a stronger voice in the world.

She admires these scientific researchers who promote the progress of the country.China's peace is silently guarded by them.She is willing to remain anonymous, willing to be silent, and willing to contribute with blood. Only then can she have the prosperity and prosperity of China in her memory.

"Just call me Lu Xiao, this nominal teacher makes me ashamed!" Lu Xiao opened the laptop he carried with him, derived the model he derived last night, and turned the laptop in the direction of Wu Tong.

"Here, the aerodynamic uncertainty at large angles of attack is analyzed with a slender template. The aerodynamic and flow characteristics of the aircraft at transonic speeds and large angles of attack have three points, asymmetric separation when the angle of attack is above 30 degrees. The vortex precursor, the lateral aerodynamic force that reaches the normal force, the randomness of the precursor vortex... I think... under the logic of mathematics and dynamics, find a special compensation mechanism, the greater the angle of attack , the worse the randomness of the phenomenon!”

The problem of high angle of attack bypass flow has always been a serious problem that plagues fighter jets, and it can also be said to be a cutting-edge topic today.

At first, he wanted to achieve a balance of this probability through a certain shape design.An asymmetric front wing or a flat front wing layout, these are the options he is considering.It's just that most of the design schemes failed to reach the ideal value, until Wu Tong's derivation logic appeared, allowing him to see another new solution direction.

In the past, domestic aviation mostly avoided this problem by not flying at a high angle of attack, or compromised stability by widening the wing surface.But correspondingly, it will cause a series of problems. Any change on the fighter plane has always been a major event that affects the whole body.

Wu Tong stared at the data on the screen, thinking quietly. After a while, she had some ideas, pulled the draft paper and pen aside, and deduced on the draft paper.

dujdt=ρgj+xiTij, Tij=pδij+τij=pδij+2μ(Sij23
Smmδij)+μνSmmδij(3)(3)ρdujdt=ρgj+xiTij
, Tij=pδij+τij=pδij+····
After a while, Wu Tong pushed the draft paper full of writing in front of Lu Xiao.

"Momentum conservation motion of viscous incompressible fluid, NS equation?" At first glance, Lu Xiao understood Wu Tong's principle. He studied dynamics and was engaged in fighter design. How could he be unfamiliar with fluid mechanics.

Wu Tong nodded, "Yes, my logic starts from the NS equation. Let P be the density of air and fluid, V be the velocity vector, U, V, W are the velocity components of the fluid at time T and at point Z... ··We assume that...in the solution of the NS equation...directional inference, the optimal auxiliary wing length and width can be obtained..."

"Use the wing surface vortex to offset the multi-part asymmetric separation of the front vortex!" Lu Xiao continued with bright eyes. At this point, his direction was completely illuminated. He turned his hand, and with his slender and strong fingers, on the keyboard, The output of afterimages can almost be seen, this silky smoothness makes Wu Tong sweat.

It has been determined that this is a god-level realm that she cannot reach.

The model on the screen, with Lu Xiao's input, gradually took shape stably, and tended to resemble the steel eagle J-20 that she later flew over the square with a high-spirited attitude in the video of the military parade. Eagle data optimized a lot!

Wu Tong's eyes were a little twitching, and the wet water shone.

This version of the eagle, like the rebirth of the eagle, retreated and broke free from the shackles of the unnecessary aging minion feathers, put on new full-body wings, and possessed a strong heart. With lighter and stronger power, it is about to shine in the world. In front of the eyes of the world, compete with the demeanor of the most powerful fighter jets in the world, and provide infinite security guards for China's airspace!

She was able to contribute a little bit of her own strength to a better direction, and the surging joy and excitement could not be restrained no matter what.She wanted to give it the best gift, and sighed regretfully: "If the NS equation is proved and the general solution is found, our aircraft will be more perfect!" Now, it can only be a quasi-perfect form based on their existing conditions.

"I expect you to create this miracle!" Lu Xiao tilted his head to encourage him.

Wu Tong's record made him hopeful.If Wu Tong can prove the NS equation in his lifetime, he will design the best fighter jet in the world to congratulate him.

　All data and questions are purely fictitious, do not seek truth and substitute reality!We are here, I wish everyone happy, thank you for your support!
