Chapter 527 I Have Three Considerations
Everyone burst into laughter and Gao Zhendong returned to his office.

As soon as Gao Zhendong turned around, Ma Juan ran to pull Yi Zhonghai's apprentice: "Sister Qin, I'm going to be stationed in a foreign factory, you have to teach me, hehe~~~~~"

As the few female comrades in the research group, the two of them had a very good relationship. It was very common for the elder sister-in-law to take care of the younger sister in life. Qin Huairu smiled and said, "What is there to teach? I have been to the computing institute, and you have also been to the computing institute. It's the same, haha."

The two women laughed together.

As soon as Gao Zhendong entered the office, he immediately called Chief Engineer Lu of Factory 1274.

"Boss Lu, get ready to receive the lithography machine. Also, prepare accommodation for the comrades from our factory who will come to work with the lithography machine, hahahaha."

"Photolithography of what? Ah? Photolithography machine? It's done? Hahaha, that's great, that's great. Don't worry, your people are here and will take good care of you." President Lu was overjoyed. Although it seemed to have taken a lot of time, in fact, this progress had far exceeded the most optimistic estimates of President Lu, Factory 1274, and even the th Ministry of Machine Building.

Fang Yinghong was still there with a team supporting the improvement of the diffusion furnace. Before she left, the second group of comrades were about to go there. It was a successful meeting.

The news of GK-61's success soon reached the headquarters of the Third Rolling Mill, and then spread along the wires from the headquarters of the Third Rolling Mill to the Seventeenth and Twelfth Machine Ministries, the Defense Work Committee...

“Fortunately, it was made in 61.”

"Fortunately, it wasn't last year."

The leaders of the 17th and 12th Ministries of Machine Building, looking at the good news and then at the list of science and technology awards at hand, made the same exclamation.

The comrades from the Publicity Department of the Third Rolling Mill were very skilled in their work. They swiftly carried their pens and photographic equipment and, after numerous inspections, came to the trial production workshop of the lithography machine. Come on, come on, let's take pictures.

Gao Zhendong is still not in the photo.

Decades later, a question was asked on a famous Q&A website: "Since Gao Zhendong is said to have achieved so many successes, why is he rarely seen in various celebratory photos?"

This style of shooting the arrows first and then drawing the target and asking questions is something that anyone who understands will understand.

The most-praised answer below answered it like this: "Thanks for the invitation. I just got off the plane. I'm in Beijing, studying for a PhD, and I'm barely free. Mr. Gao doesn't need to appear in the photo, but the motherland needs him not to appear in the photo. You idiot!"

Looking at the front page of the daily newspaper with the headline "my country's integrated circuit technology has made a major breakthrough" and the subtitle "The world's leading GK-61 lithography machine has been successfully developed", Gao Zhendong felt quite complacent.

It is not a bad thing to be proud of your own efforts. As the saying goes, this can provide extremely high emotional value. Just be careful not to become complacent and arrogant, forget your original intention, and become complacent.

The report did not introduce any details of GK-61, and even the words "proximity" and "10μm" were not mentioned. It was just a very simple name, a lithography machine from 61, with a brief introduction to its purpose and significance. The rest was praise for scientific and technological workers and prospects for the future.

In Gao Zhendong's previous life, when companies issued press releases, for the sake of publicity, traffic, and gimmicks, they would give mysterious names to any product when reporting on it. They would cram in "nano", "quantum", "AI", "graphene", "superconductor", etc. But these days are different. The main thing is to use a name that makes you understand what it is without letting you know what it is used for.

At this time, someone came to see him.

When he arrived at the reception room, he didn't recognize the person, but as soon as he was introduced, he recognized him as an old senior!

——Mr. Xiao from Cifei Factory and one of his colleagues.

When General Xiao arrived in Beijing, he first asked the Defense Work Committee about the source of the forwarded email. The comrades from the Defense Work Committee responded very promptly and told him the information without even asking for instructions from their superiors. They also gave him a letter of introduction, which seemed to be well prepared.

With the letter of introduction in hand, General Xiao expressed to the comrades of the Defense Working Committee his desire to report matters related to the Attack-5 aircraft to the relevant departments. The comrades of the Defense Working Committee said that this matter must be reported first before a decision can be made, and asked him to wait in Beijing for a few days and visit the people he wanted to visit first.

Knowing that this matter could not be rushed, Mr. Xiao turned to the Third Rolling Mill.

On the bus to the Third Rolling Mill, Mr. Xiao kept looking at the name of the factory in confusion. It was definitely not the case that airplanes had nothing to do with this place, but to say that they had much to do with it was not that important.

Looking at the comrade we are going to find, he is not even a senior technician of the Third Rolling Mill, but the chief engineer of the Third Rolling Mill. This is even more puzzling. The name of the Third Rolling Mill of the Seventeenth Ministry of Machine Building and this person's name seem to have heard of somewhere before.

With the letter of introduction, Mr. Xiao entered the main gate of the Third Rolling Mill without much trouble. However, when he entered the third branch of the Mill, he realized that things were not simple.

The procedures and processes for identity verification in the Third Branch Factory are extremely strict. Even if it is loose on the outside and strict on the inside, there is no reason why the gap is so huge.

Fortunately, the comrades at the Third Factory were very enthusiastic, but the inspection was very strict.

When Mr. Xiao went through the cumbersome process and saw the man at the door in the reception room, he was even a little dazed for a moment. He was too young!
However, Chief Engineer Gao was very enthusiastic towards the two of them. He invited them to sit down, handed them cigarettes, and served them tea and water himself without asking anyone else to do it.

This guy is quite nice, Mr. Xiao’s colleague thought.

How could Gao Zhendong not be enthusiastic? As a veteran military fan in his previous life, he knew what he understood.

After they finally sat down, Gao Zhendong cheerfully brought up the topic: "Mr. Xiao, has the last issue with the 16mm and 8mm steel cables been resolved?" When these words came out, several people were stunned.

Gao Zhendong was really dumbfounded. Oh my god, I slipped up. I shouldn't have mentioned this. It's easy to get killed by chatting like this.

The reason why Mr. Xiao was confused was that he knew why he always felt that he had some impression of this unit and people along the way. It turned out that the comrade in the factory wailed and embarrassed himself in Beijing last time, and that expert was the young man in front of him!

This guy doesn't seem that good! Mr. Xiao thought.

Several people laughed awkwardly, and Mr. Xiao said, "It's solved. Thank you so much, Mr. Gao, for that matter."

As for why I’m thanking you, I can’t say it out loud. It’s a bit exaggerated, so I’ll just be vague about it.

Gao Zhendong was too embarrassed to dwell on this matter. He also felt that it was not something to be proud of. The main reason was that the problem was a bit too nonsensical. Apart from being funny, it did not give him any sense of accomplishment.

In fact, placing the machine gun in front of the air intake is not much better than this.

"No, no, let's not talk about that. Mr. Xiao, what is the matter that brought you to me today?" He guessed that it might be because of the attack -5, but he couldn't be sure. After all, it was possible that he was found for the materials. This should be his most famous reputation outside.

"It's like this. A few days ago, we received an email forwarded by the National Defense Committee. The suggestions in it gave us a lot of guidance and inspiration, but some of the things were a bit brief and we didn't quite understand them, so I took the liberty to come visit you and ask for your guidance."

Gao Zhendong didn't deserve this: "Mr. Xiao, you are too polite. I don't deserve it. If you need any further explanation, please let me know."

"It's mainly a technical issue, and also a usage issue." It doesn't sound like there are many problems.

"Well, please go ahead."

"It's the wing-body fusion technology you mentioned in your letter."

Gao Zhendong was a little confused. The meaning of this thing can be understood just by looking at the literal meaning.

This is because he had a preconceived idea. He had a relatively systematic understanding of wing-body fusion, so he felt he could understand it at a glance.

But many times, if we only look at the literal meaning or just hear the pronunciation, we really cannot understand it because there are too many polyphonetic and polysemous characters.

"Wing-body fusion, that's what's going on..."

It seems that Mr. Xiao is very rigorous. Gao Zhendong admires him and introduces the concept, advantages and disadvantages of wing-body fusion.

After listening to Gao Zhendong's words, Mr. Xiao nodded and pondered. So that's what was going on. Then he began to make rough estimates and calculations in his head.

The more I think about it, the more interesting it becomes. This thing is really good.

The volume, drag, and lift-to-drag ratio are all good, but the positive effect on the rigidity of the aircraft will cause some noise. Proper design can indeed reduce the weight of the aircraft, but the trouble lies in this design.

Now that you're here, Mr. Xiao has nothing to be embarrassed about.

"Chief Engineer Gao, have you considered how to implement this wing-body fusion on the Gong-5?"

Gao Zhendong actually thought about it: "I have seen the main structural design drawings of Gong-5, and there are indeed some considerations, but they are not mature."

"No, no, we have no experience with this at all. I still hope to hear your opinion."

"Then I'll just say it casually. I have three considerations."

Three considerations? You call this immaturity?
With two emotions, "We've struck gold" and "What nonsense are you talking about", Mr. Xiao and his entourage opened their notebooks.

"The first method is relatively simple. On the main load-bearing frame of the fuselage, curved fillet components are added above or below the wing, and the curved fillet components are used to support the wing-body fusion surface. At the same time, a wing slat is added in front of the wing to improve the aerodynamic performance while increasing the transition and length of the wing-body fusion. At the rear of the wing, the original straight root fillet is changed to an arc transition, which can further lengthen the length of the fusion part."

The increase in volume brought about by lengthening the fusion part is not just a linear relationship, but a cubic increase.

After Gao Zhendong finished drawing, he added: "This solution has relatively minimal changes to the main load-bearing structure of the fuselage and is relatively easy to implement. Of course, there are disadvantages, such as the maintenance port for wing disassembly and assembly must be considered. In addition, the wing is inserted into a slot or half a slot, which will bring new problems to the sealing between the wing surface and the slot. We need to deal with it."

Looking at the diagram Gao Zhendong drew on paper, Mr. Xiao had more questions. What is this wing strip? What aerodynamic performance does it improve?
