Scholars in the courtyard

After Li Haonan finished speaking, there was silence in the room.

It is really too luxurious to use titanium alloy to make airplanes.

What's the difference between that and making it out of gold?

Lou Xiao'e behind her didn't know how to record it.

Zhang Guanyu raised his hand to touch his glasses. During this period, he followed Wu Zhe and others to study airplanes. Aren't airplanes made of aluminum alloy?

Wang Xushan and Wu Zhe immediately widened their eyes, and then shook their heads together, "Old Li, using titanium alloy is too expensive."

"Did you know? This titanium is more expensive than gold."

"From what you put it, how much titanium alloy does this cost?"

Li Haonan shrugged helplessly, "There is nothing we can do about it. If the speed is too fast, the surface temperature will be at least 300 degrees."

"As for other internal components, especially the engine, they must be at least a thousand degrees."

"In this case, not to mention aluminum alloy, even ordinary steel will be affected."

"If high-temperature-resistant materials are not used, the parts in the aircraft cannot withstand it at all. You also know that after flying into the sky, there are certain things that must be considered, otherwise it will be a crime."

After the words fell, Wu Zhe and Wang Xushan stopped talking.

Because it's true.

Everyone was silent, and then all looked at Yang Xiaotao.

Hearing what Li Haonan said, Yang Xiaotao thought it was a problem at first. After all, high-temperature materials are not cheap.

Even aircraft engines are not all made of titanium alloy, only special parts are used.

Don’t even think about using titanium alloy for the entire aircraft.

Even if it is designed, it is estimated that the superiors will not agree to manufacture it after seeing it.

But after listening to it, I realized that this was not a problem at all.

Seeing everyone looking over, Yang Xiaotao straightened up, then knocked on the table with a serious expression, "First of all, the speed of the aircraft is a mandatory requirement. There is no way, because the missiles are getting faster and faster."

"If you are slow, look at the results in Shanghai and you will know that there is no chance of success."

"Just don't make planes like that."

Everyone nodded silently after hearing this.

Instead of producing targets that are slow, why not go all out and produce better ones.

It’s just that this high-temperature-resistant material also...

Too expensive.

How can the country have so much money?

Just when the three of them thought that Yang Xiaotao would say no matter the cost, they heard Yang Xiaotao ask a question, "Does any of you know how high a temperature our stainless steel can withstand?"

There was a moment of silence in the conference room.

What?

Stainless steel?

What does it mean?

Wang Xushan said uncertainly, "About three to five hundred degrees."

"But there are special stainless steels that can withstand temperatures of a thousand degrees."

After Wang Xushan finished speaking, he thought of something and asked in surprise, "No, Mr. Yang, you, you don't want to make it with stainless steel, do you?"

"This, this will affect the overall layout of the aircraft body, and stainless steel is too heavy. Our engine only has 8,000 thrusts. If it is too heavy, it will be difficult to break through the thermal barrier, let alone Mach 3."

After Wang Xushan finished speaking, Wu Zhe also expressed his objection, "Mr. Yang, this stainless steel is indeed resistant to high temperatures, but its weight is not suitable for such a high-speed aircraft."

Li Haonan also agreed with the two people's opinions.

Yang Xiaotao waved his hand, didn't he know if he could do it?

I really thought the MiG-25 was blown out of proportion.

If others can use it, why can’t I use it?

After the three of them finished speaking, they found that Yang Xiaotao was not moved at all, and the three of them felt a little helpless.

Why can’t the Lord in front of me listen to his opinions?

But they have no choice but to reserve their opinions.

"Since stainless steel is resistant to high temperatures, it means it can be used."

"As for motivation."

"If one engine doesn't work, then two engines will do."

Yang Xiaotao spoke again, and the three of them were stunned again.

Two engines?

this.

This has never been done before.

The MiG-21 that Shengjing is imitating now uses one engine, and the one being tested now is also the same engine. They have no experience with these two engines.

"Yes, just use two engines."

"My opinion is to put the two engines on both sides of the main shaft so that the power can be guaranteed."

"Of course, such a plane might be a little bigger, but it should be fine."

When Yang Xiaotao expressed his thoughts, the people around him found it difficult to accept it.

Most of today's fighter jets are single-machine in order to maintain flexibility.

Only larger bombers will use two or more engines.

What Yang Xiaotao said now made them wonder, is this going to be a fighter jet or a bomber?

After Yang Xiaotao finished speaking, there was a silence among the people around him.

"Mr. Yang, have you already made the design drawings?"

Wu Zhe finally couldn't help it anymore and asked what was in his heart.

He felt that Yang Xiaotao must have his own design plan. Instead of squeezing out bit by bit here, he might as well open the skylight and speak out and ask for clarity.

The other two people also stared at Yang Xiaotao with burning eyes after hearing this.

All things at the moment made them feel as if Yang Xiaotao could come up with a complete set of design drawings.

Yang Xiaotao was stunned for a moment. Seeing that everyone looked serious, he quickly shook his head and said, "No!"

"If I had, I wouldn't have needed to look for you, I can do it all by myself!"

Unexpectedly, as soon as Yang Xiaotao finished speaking, several people still looked at him suspiciously.

Zhang Guanyu, who was standing by, was even more certain that Mr. Yang must be researching airplanes in private.

The reason why he didn't expose it was to save face.

He must work hard.

Looking at the expressions of the other people, Zhang Guanyu quickly said, "Mr. Yang, don't worry, we will definitely complete the task!"

Zhang Guanyu, who had been silent all the time, suddenly said this. Not to mention Yang Xiaotao, even Wu Zhe and others were stunned.

However, Yang Xiaotao came back to his senses and smiled, "Okay, I'll wait for your good news!"

The meeting basically determined the general work arrangements, and Yang Xiaotao didn't stay in the R\u0026D department for long. After the meeting, he went to the office.

After Yang Xiaotao left, Li Haonan and Wu Zhe looked at Zhang Guanyu, not understanding what he meant by that just now.

"Everyone, you may have been in the machinery factory for a short time and don't know Mr. Yang very well!"

Zhang Guanyu patiently explained, "Mr. Yang has a habit of being democratic in everything he does!"

"Democracy?"

Several people blinked their eyes, wondering why this honest man in front of them started to lie.

For a moment, they doubted whether his previous performance was fake.

"Yes, we have worked with Mr. Yang for too long! So we know Mr. Yang's style very well!"

"When he wants to do something, he will let us do it first, but in fact, Mr. Yang has made preparations in advance!"

"Mr. Yang never fights without confidence. Generally speaking, he will do the research topics for us first, at least he has a direction!"

"Letting us do it is actually helping us grow!"

"You think Mr. Yang is arbitrary in some things, but in fact, as long as Mr. Yang is arbitrary, facts have proved that there are problems!"

"You don't know that when we designed the aircraft engine, we also made many suggestions..."

As Zhang Guanyu explained, the original suspicion of the three people gradually became solemn, and then thinking of Yang Xiaotao's "achievements", this solemnity became normal.

When the three left the R\u0026D department, Li Haonan and Wu Zhe walked together, and both of them pondered Zhang Guanyu's words.

"Maybe, Mr. Yang is really democratic!"

Wu Zhe nodded slightly after listening.

"Maybe, he really has a direction?"

At this point, the two looked at each other, and then laughed helplessly.

To put it bluntly, this special group is still mainly based on the Red Star Machinery Factory, and Yang Xiaotao is the core.

After all, it's all for the purpose of making use of the engine.

Others design their own engines, so they must know more about them than themselves.

So, just listen to them, that's right!

After the two of them figured it out, they also found the direction. Whatever Yang Xiaotao asked them to do, they would do it!

On the other side, Yang Xiaotao sat in a chair after returning to the office and thought about what had just happened.

It has to be said that designing aircraft and designing aircraft engines are completely two different fields.

Yang Xiaotao felt a little bit strenuous.

It's like a mountain between two different fields. Although he knows a little bit, he feels very strenuous when he really does it.

For some things, I know how to choose, but I can't give a reasonable reason.

Just like the double vertical tail we talked about today, if he can understand the benefits of the double vertical tail and its role in the aircraft, then he still needs to use his brains and spend his words to convince them?

If he could master aerodynamics and aerodynamics, would he need to go through so much trouble?

Unfortunately, he is really not good at this!

Moreover, mastering these aspects is just the beginning. The aircraft shape, center of gravity, and the angle of the aircraft wings, etc., all of which require scientific demonstration.

Even an inconspicuous angle problem may lead to a serious accident after flying into the sky.

Yang Xiaotao rubbed his eyebrows with both hands, feeling a little uneasy.

Now the only thing he can rely on is the system!

But if he wants to fix the system bug, he must have his own design drawings.

But now, with his half-baked level, if he gets involved, he will only get half the result with twice the effort, or even make things worse.

"So, now that things have come to this, I can only study!"

Yang Xiaotao suddenly laughed.

Reading, I haven't studied seriously for a long time.

Earlier, Yang Xiaotao could still get credits from books.

But as the credits required for upgrading increased, the 100 points given by reading were not enough.

Therefore, in order to obtain credits as quickly as possible, Yang Xiaotao embarked on a path of independent "design".

Make a design drawing of the machine, obtain a large number of credits, and then upgrade it, and then use the rewards after the upgrade to improve strength.

Yang Xiaotao has been doing this all the time, so he rarely has time to read books.

Of course, Yang Xiaotao can find many reasons, such as being busy with this and that, but fundamentally, he still puts reading behind time.

So when there is no time, reading is forgotten!

Just like the artillery detection radar that was rewarded before, those books are also not read much?

I feel that I am a little sorry for the name of this system.

The system asks you to read, but you use the system to do private work.

It's a bit upside down!

Yang Xiaotao suddenly laughed at himself, "The road is a bit off!"

"Reading is to lay a solid foundation. If there is no foundation, how can you design!"

After that, Yang Xiaotao re-planned the focus in the future.

Reading will become an important part in the future.

And now, the first step is to learn aerodynamics.

At the very least, you should finish reading the relevant books!

Thinking of this, Yang Xiaotao stood up and walked out.

Lou Xiaoe felt that Yang Xiaotao's face was not right after entering the office.

Then he saw him sitting there alone, thinking hard, frowning for a while, then smiling bitterly, and finally he stood up and walked out in a hurry.

"Boss Yang, where are you going?"

Lou Xiaoe asked rashly, and then quickly added, "Do you want me to go with you?"

Yang Xiaotao paused and then waved his hand, "No, I'm going to the Seventh Ministry of Machine Building!"

After saying that, he had already walked out of the office.
