Shaking his head as if he had been split by an axe, Wang Yinan was woken up by the sun near noon, hey, how can I say it, let me think about it...

Well, it was the same very small and tidy guest room, the same dizziness, Wang Yinan remembered the experience of getting drunk half a year ago, and it seems that he should drink less wine in the future. Washed his face and walked out of the door, and played a set of tai chi activities to move his muscles and bones, this time there was no Deng Ruoyan applauding beside him, and Qian Zhonghua tried to recruit on the side.

Because the hostess of the club has also drunk a lot, I guess she is still lying down. Wang Yinan didn't wait for her, and said goodbye to the waiter, there are still many things arranged today, although the company has been on holiday, and the employees have gone home one after another. Wang Yinan still has a very important thing to do, and this is also the last job of the year.

Wang Yinan hurried to the airport and bought a ticket to Shudu recently, Chief Yang of the 116 Institute was still waiting for him, Wang Yinan called him yesterday, and made an appointment to go to the 116 Institute to talk to Chief Master Yang today.

In helping a certain Hoy in the northeast to improve the design of the aerodynamic and flight control system of the fourth secondary school, Wang Yinan and they suffered from lack of data, and adopted the method of abandoning the existing data and training directly from scratch, but after obtaining good results, Wang Yinan has been thinking about discussing with Chief Master Yang what kind of performance will be performed if the training method of Ge Kunpeng 2.0 is also used in the fourth-generation stealth fighter of the 116 Institute.

But unlike the middle four of a certain Hoy that is still on paper, the fourth-generation stealth fighter of the 116 Institute has been proven to be a quite successful design, you know, it takes great courage to deny a successful design, Wang Yinan asked himself, if he faced the same situation, he would be very difficult. Therefore, Wang Yinan did not say this on the phone, but just told Chief Yang that he was going home for the New Year, and he happened to pass through Shudu and had time to chat.

Because it was a temporary flight, Wang Yinan did not let the 116 Institute send someone to pick him up. After the plane landed at the airport, he called a Dada Express, came to the 116 Institute located in Shudu City, brushed his face and walked into the gate of the 116 Institute (Wang Yinan's popularity in the 116 Institute is not covered), for the 116 Institute, Wang Yinan is also familiar with the road, as soon as he turned, Chief Yang was waiting at the door of the No. 10 fighter model.

Under the sun, the model of the No. 10 fighter looks particularly beautiful, this is the pride of the 116 Institute and even the entire Chinese aviation industry, and it is also the foundation of the 116 Institute, when the Air Force was still relying on the second-generation fighter to support and protect the sky of China, it was the 116 Institute of Song Lao Shi who overrode public opinion, and used a model made of plexiglass and the most advanced at that time, the refreshing theory of energy maneuver air combat impressed the relevant experts who participated in the seminar. Created the No. 10 project, which is the foundation project independently developed by Huaguo.

It was also Mr. Song who was able to confidently say when Hoy 27 entered China and showed performance far beyond that of the second-generation aircraft, "Our No. 10 is superior to Hoy 27 in some aspects." Because of his self-confidence and the support of the veteran generals of the Air Force, in the army, "to Erqi, to have more Erqi", the No. 10 project was retained.

He did not break his promise, and in the many confrontations between the No. 10 fighter and the Hoy 27, the autonomous No. 10 fighter did not fall behind, but often achieved overwhelming results of 2:0 and 4:0.

Chief Master Yang greeted him, "A man, if you have time to come to us for inspection, why don't you come early, it's the New Year, many colleagues have gone home, and there is no way to entertain you well."

"You're too polite, I'm mainly going home, and I'm here to walk around you," Wang Yinan said.

"If there is anything difficult to do, just say it", Chief Teacher Yang said,

Wang Yinan was depressed, why have you learned to read minds all these years, why haven't I spoken yet, can I guess what is difficult, or am I too upright?

"There is a difficult matter, but it is not that I am embarrassed, I am afraid that you will be embarrassed, and I don't know whether to talk about it or not", Wang Yinan said,

"What's the matter, just say it, who are the two of us, besides, what do I have to embarrass about, it's a big deal if I don't hear it",

Wang Yinan thought about it, it seems that I still think too much, "Do you remember a certain Hoy's G old man, didn't he ask us to help them improve the pneumatic and flight control system of the self-developed middle four?"

"Yes, this is what I know, how is the progress, is it convenient to say", Mr. Yang replied.

"There is nothing to keep secret about you, the effect is not just good, but very good", Wang Yinan said, "Compared to you, their tests and test flights are very small, and the test data and supercomputer simulation data add up to less than one-tenth of your data volume."

"The number of samples used for training should be insufficient", Chief Yang obviously saw the crux of the problem.

"Yes, it is because of the extreme shortage of samples, we have no choice but to refer to the latest Mi Ge paper on dog eggs, just input the basic physics, especially the rules of aerodynamics, and then carry out zero-shot training",

"Wait, you're saying you didn't use any artificial simulation or test data at all", Chief Yang was obviously a little dizzy.

"Yes, we let Ge Kunpeng learn to fly from scratch by himself, and slowly learn to fly freely from trial and error."

"What is the result", Chief Engineer Yang asked,

"Very good, even better than having a sample, Ge Kunpeng finally got the suggested optimal conventional layout aerodynamic scheme, which is very similar to the YF23 verification machine in the United States, which proves the feasibility of this zero-shot training to some extent."

"So you came to me because you think that if you use your latest zero-sample training method to simulate the training of our fourth-generation stealth fighter again, there may be better results", Chief Engineer Yang immediately thought of the purpose of Wang Yinan's visit.

"Theoretically, this is the case, but you are different from a certain Hoy, a certain Hoy's Form 4 is just a prototype, so the modification of the flight control system, and even the modification of the aerodynamic shape, the problems involved are much simpler, and your fourth-generation stealth fighter has passed the first stage of acceptance, is a relatively mature system", Wang Yinan said,

"It's okay to just modify the flight control code, in case Brother Kunpeng proposes to modify the aerodynamic shape, it may be very difficult for you."

Chief Master Yang understood Wang Yinan's concerns, he pondered for a long time, and said to Wang Yinan, "You come with me",

Chief Engineer Yang took Wang Yinan around the back of the No. 10 fighter model, the engine compartment, Chief Engineer Yang pointed to the engine room at the back of the No. 10 fighter, and said to Wang Yinan, "At the beginning, No. 10 was scheduled to use the domestic WS-6 engine, so the entire engine compartment was designed according to WS-6."

"But later, due to the lack of domestic basic industry, the WS-6 was constantly postponed, and it may even be canceled, and we faced the problem of no engine available. So as a last resort, we chose the third aunt's engine as a replacement, and everything was normal after the third aunt was installed for test flight, but compared to the original WS-6, the third aunt was longer and thinner, and the prototype simply lengthened the fuselage".

"After the prototype test flight was completed, we had two options, one was to maintain the fuselage lengthening scheme, which would cause a waste of space and a certain loss of performance."

"But safely",

"Another plan is to modify the engine shape according to the new third uncle, and even rebalance and re-blow the tunnel, which has the advantage of the best performance, the disadvantage is that there will be risks, and the progress will be delayed."

"My predecessor, Mr. Song, only said one sentence in the end",

"I don't want to leave regrets".

Chief Engineer Yang pointed to the slender and extraordinarily beautiful engine compartment at the back of Model 10 and said, "This is Chief Song's answer, and it is also the spirit of our 116 Institute, leaving no regrets."

Wang Yinan's eyes were unconsciously filled with tears, not long after the successful test flight of the fourth-generation stealth fighter of the 116 Institute, Chief Master Song passed away, but the spirit of no regrets advocated by him was passed down in the eyes of Chief Master Yang and those inconspicuous 116 engineers.

It is no wonder that in the case of resources and attention far less than a certain Hoy, 116 was able to grab the No. 10 project, and even left a certain Hoy far behind in the competition of the fourth generation of stealth fighters. Thinking of a certain Huo Yi who has been hesitant so far, Wang Yinan sighed secretly, their exam questions are more than ten times easier than those of 116, I don't know what kind of choice they will make.

Coming to Chief Engineer Yang's office, Wang Yinan and Chief Engineer Yang and several engineers who did not go home discussed the Ge Kunpeng 2.0 scheme for the 116 stealth fourth-generation aircraft, and everyone agreed that the 116 Institute would prepare the latest aerodynamic shape and engine power parameter curve of the stealth fourth-generation in advance, and immediately hand it over to Ronghe Company for sample-free neural network training after returning from the Spring Festival holiday.

The specific improvement plan will be discussed after the results of the neural network training are available, but it is clear that Chief Yang and the 116 Institute are ready for a major overhaul.

After being busy, Wang Yinan said that he had finally drawn an end to this year's work, and walked through a back door, Wang Yinan borrowed a military jeep from 116, although it was not so comfortable to drive, but it was big enough and cool, the so-called "wealth does not return to the hometown, such as brocade clothes at night", Wang Yinan couldn't drive Pingzhi back, and he always had to get a jeep to pretend to be a façade.

Cotton City, the city where Wang Yinan's hometown is located, is only more than 100 kilometers away from Shudu, Wang Yinan ran all the way, and finally returned to a research institute on the outskirts of Cotton City before dark.

Under the sunset, the research institute located under a hill is clothed in a beautiful glow, and the gate of the institute with a history of several decades has been a little dilapidated, no different from when Wang Yinan left two years ago.

Wang Yinan opened the car window and let the cold winter evening breeze blow his hair, "I, Wang Hanshan, am back again!" ”
