Scholars in the courtyard

Yang Xiaotao stayed in Qian Lao's office for the whole morning. If Ran's father hadn't come to report the situation, the two of them would have forgotten to eat lunch.

So the three of them went to the restaurant to eat together. After eating, they immediately returned to the office and continued the discussion.

However, this time the discussion originally between two people became a discussion between three people.

Ran's father can also help provide ideas for rocket research. Sometimes, starting from the perspective of rockets, there is a sense of sudden enlightenment.

In the afternoon, the communication between the three people was considered to be over.

It had to end. Yang Xiaotao was young and had no physical problems. Ran's father was also in his prime and could handle it. However, Qian Lao's physical and energy could not keep up, and Yang Xiaotao could not trouble him anymore.

Besides, Qian Lao himself had a lot of things to do.

The rocket that transported the satellite to the sky was still making the final sprint.

It was a huge help to come here to "learn from the past" today.

Seeing this, Yang Xiaotao prepared to say goodbye.

Mr. Qian nodded, then returned the record to Yang Xiaotao, and gave him two more books, also about aerodynamics, all of which were basic knowledge.

In Mr. Qian's words, once the foundation is laid, some things can be figured out and discovered by yourself.

Then he said to call if you encounter any problems, don't be embarrassed.

He also reminded that if there is any progress, you should tell him as soon as possible.

This sincere heart, in addition to being moved, is more like a kind of inheritance for Yang Xiaotao.

A feeling of passing down the burden of national rejuvenation.

Leaving the Seventh Ministry of Machine Building and returning to the Machinery Factory.

Sitting at the table, Yang Xiaotao was like a daze, without any movement, and there was no focus in his eyes.

Lou Xiao'e on the side was a little at a loss. Seeing Yang Xiaotao motionless, she didn't dare to move either.

When asked what was the matter, Yang Xiaotao just shook his head and didn't speak.

At this time, Yang Xiaotao himself didn't know why this happened, but he knew that Mr. Qian's attitude was still infecting him.

After a long time, Yang Xiaotao came out of this feeling. He liked this feeling very much, because every time he thought about it, he would have an inexplicable sense of mission.

Yang Xiaotao, who had recovered, also made Lou Xiaoe feel relieved.

If it was still like this, she would have to go out and call the medical station.

The old man said that people who have minor illnesses all the time don't have serious illnesses, but people who don't have minor illnesses will have a big one.

Mr. Yang, it is very likely the latter.

Lou Xiaoe felt that she had to remind Ran Qiuye when she went back.

At this time, Yang Xiaotao didn't know what Lou Xiaoe was thinking, and even if he knew, he wouldn't care.

In their family, let alone him, even the children in the family rarely get sick.

The reason, of course, is that Xiaowei is here.

At this moment, Yang Xiaotao is busy making short-term plans.

First of all, he promised to do what the Chinese Academy of Sciences had to do, and this matter was handed over to Zhang Guanyu and others, so that the technical team of the R\u0026D Department could practice.

With the help of Mercury Machine Tool this time, I believe that there will be no need to waste so much material during production and processing.

Of course, the material benefits promised by the Chinese Academy of Sciences cannot be reduced.

Let Lao Yang negotiate this.

Secondly, it is the design of the aircraft.

Although Chen Lao, Xia Lao and others did not say anything, it can be seen from the visits that they attach great importance to this aircraft.

Moreover, we need to come up with a solution for the little black bird.

Just looking at the current situation, the Thunderbolt 3 taken out by the Seventh Ministry of Machine Building lacks a suitable carrier, and it is not easy to come up with a suitable carrier in a short period of time.

Of course, the Thunderbolt 2 they are currently working on is also possible, but the research and development of Thunderbolt 2 is not going smoothly.

Father Ran told him that if you want to increase the range, you need to consider factors such as weight, volume and fuel.

And the most important problem they have not solved yet is the guidance device.

Nowadays, infrared guidance is installed on missiles.

It just so happens that the little black bird flies fast, and it is difficult to capture it. Sometimes you predict the opponent's trajectory in advance and fire head-on, and the other party can avoid it.

Even if you control the detonation, you can avoid it.

This is the problem.

If this is not solved, it is estimated that developing air-to-air missiles will also be a problem.

Therefore, Yang Xiaotao felt that he needed to take out this plane as soon as possible.

Even if he could not catch up with the black bird, he could scare it from behind, and it would be best to find a launch platform for the missiles of the Seventh Machine Department.

Not like now.

The last task is the helicopter engine in Jinling.

Speaking of which, this should be relatively easy.

Yang Xiaotao also did a lot of work in the early stage.

It's just that I haven't heard the sound of the system so far, and over time, it has been put behind.

At present, I can't ignore it. After all, if you get the benefits and don't do anything, it's easy to make people feel disappointed.

As for the affairs of several other research institutes, Yang Xiaotao plans to let them go.

Let them do it themselves.

More than half of these 67 years have passed, and everyone knows what's going on.

Arrange things properly, work during the day to study airplanes, and go home at night to study helicopter engines.

After making up his mind, Yang Xiaotao called people to a meeting.

After everyone sat down in the conference room, Yang Xiaotao looked at the time and decided to make it short.

"It's almost time to get off work. Let me tell you about my recent arrangements."

Then Yang Xiaotao emphasized the key tasks of the workshop, R\u0026D department, technical team, etc. Human resources began to tilt towards aircraft design and manufacturing.

"Director Wu, Lao Wang, please take note of this."

"It is the beginning of July now. I have to be in charge of the relevant design team and come up with a finished design for me by the end of the month."

"It must be done according to the previous design direction and the original requirements."

"Whoever fails to complete the task will be held responsible."

In the conference room, everyone saw Yang Xiaotao so serious for the first time.

However, no one felt it was wrong.

Everyone knew about the black bird.

They also heard about the things in Shengjing.

Nowadays, not to mention the domestic, there is no successful interception case even in the alliance.

Their planes may be fast, but they really have not been able to shoot down the black bird for the time being.

"I know it will be difficult, but it is not our turn to do something that is not difficult."

This sentence made everyone think about it, and they instantly felt a sense of mission.

In the following time, the entire aircraft special team worked hard to overcome difficulties, and Yang Xiaotao, who had been away from home before, also began to participate.

Time passed quickly, and a week slipped away quietly in a place where no one noticed.

Machinery Factory, R\u0026D Department.

Yang Xiaotao and Wu Zhe looked at the design drawings that had just been made.

Wang Li was standing carefully at the side.

Although he was over 50 years old, he was like a primary school student meeting his teacher in front of Yang Xiaotao. His fingers were twisted together behind his back and his face was extremely nervous.

"Mr. Yang, I still think that this 45-degree sweep angle is still too large. Although the wings of normal fighters are only between 20 and 60 degrees, most of them are around 30-40. Such a large sweep angle will affect the stability of the aircraft."

Wu Zhe expressed his opinion and didn't understand why Yang Xiaotao insisted on such a large sweep angle.

Hearing Wu Zhe say this, Yang Xiaotao did not give an accurate answer, but just looked at the design drawing given by Wang Li.

This design drawing was based on his requirements. Of course, he only gave a few requirements, such as the sweep angle should be 45 degrees, the reverse angle should be 6 degrees, and the others should be based on general data.

Of course, this kind of thing is done by a professional team.

Just like the design of this wing, there is a special team, and the team leader is Wang Li in front of him.

Sitting back in his original position, he coughed lightly and then looked at Wang Li.

"Engineer Wang, tell me."

When Wang Li saw Yang Xiaotao asking him, he felt a little flustered.

"This. Mr. Yang, Director Wu, this, I think that this kind of design should be viewed from the overall perspective. If we simply say that this angle is not good, that angle is not suitable, it is a bit one-sided."

Wang Li said a lot, but in the end there was no affirmation, that is, he did not offend either party.

In fact, he still leaned towards Yang Xiaotao, because this matter was Yang Xiaotao's idea.

To put it bluntly, their special group worked according to Yang Xiaotao's requirements.

Just like the wing we are making now, the angle is 45 degrees, and there are 44 degrees, 43 degrees, and so on to 40 degrees.

And this is just the beginning, there are also requirements for the reverse angle, which are 3 degrees, 4 degrees, and so on to 7 degrees.

However, this is just an appetizer.

Yang Xiaotao said that the 45-degree sweep angle should be matched with various reverse angles.

That is to say, each angle of the sweep back must have a different degree of required reverse angle.

This is not a design problem, it is a math problem.

But what can they do?

Wang Xushan had previously said implicitly that this would not work, and that it was necessary to design and calculate at the same time, and then modify it according to the actual situation.

This is the mainstream way of aircraft design.

This is done both at home and abroad.

But what about them, ahem.

After hearing Yang Xiaotao's request, Wang Li felt that he was accompanying General Yang to draw.

Even this was not his feeling alone, all the people in the special group thought so.

But, they dared not say it.

It's not that they are timid or have no courage.

I love my teacher, but I love the truth more.

They have this kind of pride of scholars.

But.

"Then tell me, how to do it."

"Can it be done according to what you said?"

In just two sentences, General Yang refuted Wang Xudong speechlessly.

Let them not care about anything else.

Let Wu Zhe open his mouth and lose his spirit.

Of course, everyone wanted to see if they could make it according to what Mr. Yang said.

"Go ahead, continue."

Seeing Wu Zhe stopped talking, Yang Xiaotao waved to Wang Li, then looked at the design drawings on the table, confirmed the number, and then handed it to Lou Xiaoe, who then put it in a wooden box.

There were more than ten wooden boxes of this kind, neatly placed against the wall.

At this moment, each wooden box had a name on it, some with wings, some with winglets, and some with power systems.

There were now many design drawings in each box.

And after each set of design drawings was completed, Lou Xiaoe would make a set in order, and then Yang Xiaotao would look through them.

This was Yang Xiaotao's method.

There were too many design drawings for the aircraft, and it would be too slow for him to try them one by one.

He might as well let his subordinates come together, since they were all professionals and he was relieved to do it according to different requirements.

So he came up with this method, which was much more convenient than drawing it himself to get a bug in the system.

"Old Wu, you and Old Wang need to speed up the overall design. The other teams are making rapid progress, but you two are still lagging behind."

Yang Xiaotao stood up and prepared to go back to the office to look at the design drawings made earlier and communicate with the system.

Other comrades have worked so hard, so I can't relax.
