Scholars in the courtyard

Sure enough, Xu Fenghua straightened up again, but this time he looked at Yang Xiaotao with respect, "Boss Yang, I want to know, if you design a turbojet engine with a diameter of half a meter, how much pressurized thrust can be achieved?"

After saying this, another person stood up with a notebook in his hand, "Boss Yang, Director Xu, I'm sorry, I want to add something."

Yang Xiaotao didn't care, Xu Fenghua smiled and then indicated that it was okay.

"According to the weight of our current Red Flag, after we replaced the fuel inside just now, according to the volume and density, if we use a half-ton engine, as long as the power reaches 3,000 to 5,000 kilograms of thrust, it can fully reach the current speed. And the range of the missile will be increased to 40 kilometers"

As the man spoke, he flipped through the notebook, and the data on it were said one by one, which made people have to believe it.

Yang Xiaotao listened carefully, and at the same time envied in his heart, this efficiency, this ability, this

When will there be a group of people like this in the machinery factory.

Yang Xiaotao listened to the people below constantly talking about the calculation results. He was envious and calculated quickly.

"Mr. Yang, I'm sorry I said too much."

The man spoke out the data on the notebook, and then realized that he spoke too fast and too much after he finished speaking. He was a little embarrassed, but the people around him were used to it.

"No, no, I remember it."

Yang Xiaotao waved his hand, then took a step forward, quickly recalled the data, and then smiled, "Comrade."

"Wang Jinhua, Director Wang."

Ran's father reminded him from the side.

"Hello, Director Wang, the question you just raised is very good."

"Although these are all calculated data, I can't give you a specific answer."

"However, according to my guess, our missile engine is only disposable, so only one afterburner thrust is needed. The high-temperature gas burning can fully utilize the heat generated by the previous solid engine."

"I think a thrust of three to five thousand kilograms can be achieved, and because the engine's own weight is reduced, the thrust will be even greater."

"In this way, I don't know if there is any connection between them. I can tell you the previous engine data. You can calculate this yourself."

"The HJX-1 engine is five meters long, nine hundred millimeters in diameter, weighs two tons, and has a pressurized thrust of 10,000 kilograms."

After Yang Xiaotao finished speaking this data, many people below quickly recorded it in their notebooks, and some people quickly communicated.

Anyway, Yang Xiaotao didn't know what the connection was, and he didn't know what the other party could calculate.

Director Wang sat down, and everyone was silent again.

Old Wang looked at Old Qian again, wanting to get an answer from him.

Unfortunately, Mr. Qian waved his hands helplessly. It was obvious that this could not be completed in a short time.

Mr. Wang was a little nervous. If the final result was not suitable, wouldn’t he be very disappointed?

In front, Yang Xiaotao was silent for a moment, and then continued, "I think there is another possibility. Everyone can consider it."

Everyone hurriedly put down their work and looked over again.

Father Ran also looked at him in surprise, wanting to hear what Yang Xiaotao might say.

Yang Xiaotao spoke calmly, "I know that missiles have a booster stage, which is the solid engine that starts first."

"If the turbojet engine is replaced, it will inevitably affect the overall weight of the missile and the fuel weight of the solid engine. It used to take 5.2 seconds to reach supersonic speed. Will it be shortened after the change now?"

"Also, have you ever considered disconnecting the booster stage after the booster fuel is consumed, leaving only the part above the turbojet engine at the top."

Yang Xiaotao said this purely because of the battle blockbusters he saw in movies and TV in his previous life.

Many missiles will throw off their tails halfway through their flight, and then their speed will suddenly increase.

After Yang Xiaotao finished speaking, the entire conference room fell into an eerie silence.

Not only the people in front, but also Mr. Qian behind him were shocked.

This is very similar to the grading of rockets, both of which discard the used parts and allow the remaining parts to achieve a higher speed.

It’s just that they used liquid engines before, and using explosive bolts to remove the booster parts can easily cause problems, which is a big risk.

But if a turbojet engine is used, the risk is very small.

Mr. Qian’s eyes suddenly narrowed, and then the corners of his mouth turned up, and soon he was full of smiles.

At this time, the conference room was like a drop of water in an oil pan, boiling suddenly.

"Old Xu, how much does the solid engine weigh?"

"Don't bother me, I'm calculating the specific gravity."

"Old Xu, consider the fuel, I don't think it should take that much."

"How much is it, four-fifths or three-quarters, don't tell me if it's more or less, give me a specific number."

"I'm calculating it."

"Go away, don't bother me."

"Old Wang, you have to consider the materials. The speed is fast, and the air friction temperature is high. Ordinary materials won't work."

"I know, I know, can you please stop talking first? Are you considering the materials now?"

"Damn, how can you calculate the weight without considering the materials? Damn it, I'll talk to Xiao Huang."

"Old Han"

Looking at the people who were originally somewhat polite in the field, they left the table and quarreled loudly one by one, just like going to a market.

Yang Xiaotao felt like a primary school student who was out of class, running around and jumping around.

Ran's father looked at the people gathered together for discussion below, and it was estimated that there would be no results in a short time.

"They are like this. Sometimes they can discuss a problem for a whole day."

Yang Xiaotao smiled, "Actually, this is the atmosphere it should have. I really like this atmosphere."

Ran's father also had a proud smile on his face after hearing this, "Of course, we have the best scientific research team here."

"Even the Second Machinery Department may not be comparable."

"I believe this. Because of you."

Father Ran shook his head and smiled after hearing this.

"If you like it, come to our place."

Suddenly there was a voice behind them. The two of them turned around and saw Qian Lao talking with a smile, but the meaning behind his words was very serious.

Even Mr. Wang was nodding.

"Chief, don't be joking. For my level, I'm pretty good here looking at the gate."

Yang Xiaotao waved his hand and refused. He knew his own situation well. He could be clever and make some suggestions. If he was asked to come to work and develop rockets and missiles, it would definitely be a rush.

Besides, my main skill is engineer, so doing this isn’t putting the cart before the horse.

"This is not a problem. As long as you agree, I will speak to Mr. Chen and the superiors on your behalf."

"And since you're here, there's no need for you to go down there, as long as you lead them."

Not to mention Yang Xiaotao, even Father Ran found it incredible.

This son-in-law is here to take his place.

Of course, he didn't care too much about this person's lack of status. He just didn't expect that Mr. Qian would value his son-in-law so much.

This is to train him as a successor.

"I know you find this incredible, but I think it's appropriate."

"Those who do science need not only people like them who are good at studying, but also people like you who can seize the moment of inspiration."

"In my opinion, sometimes it is more important to find the right direction."

"I have only seen this in one person, and you are probably the second one."

Yang Xiaotao didn't expect Mr. Qian to say this, let alone give him such a high evaluation.

For a moment, Yang Xiaotao was at a loss.

But the next second Yang Xiaotao showed a firm look, looked at Mr. Qian and said seriously, "Uncle Qian, thank you for your respect, but I think the current job is more suitable for me."

"Besides, we are a family."

"Just like this time, our cooperation is very good. The road ahead cannot be made by one person. Only with more like-minded people can the road be made."

Mr. Qian laughed after hearing this and reached out to pat Yang Xiaotao on the shoulder, "You are very good. You are always awake and know what you want. It is rare."

Yang Xiaotao readily accepted.

"You're right."

"We are a family."

Mr. Wang also smiled at this time, "That's right, we are all a revolutionary family, and we should help each other from now on."

Hearing what Mr. Wang said, Yang Xiaotao immediately became vigilant, and then quietly distanced himself, "Chief, you don't want to default on the debt, do you? The materials used in this engine are not simple."

"It's easy to talk about these design drawings. I regard it as a contribution to the revolution, but you can't erase the materials produced."

"Mr. Zhou from the Sixth Machinery Department came up with most of the materials."

A trace of embarrassment flashed across Mr. Wang's face, but he quickly straightened up and said, "What are you talking about? We in the Seventh Machinery Department are the kind of people with no integrity."

Yang Xiaotao shook his head, "Of course not the comrades of the Seventh Machinery Department, but you..."

Hearing this, Mr. Wang's eyes widened, "You brat, are you looking for a beating?"

Yang Xiaotao quickly shrank his head and walked behind Mr. Qian. Father Ran looked at him and shook his head.

This brat can't be respected, he is their boss after all.

Mr. Wang stared at Yang Xiaotao and suddenly laughed, "I think I should give you an honorary officer of the Seventh Machinery Department, just like the Academy of Agricultural Sciences."

"You can come and help me when the time comes. You are all contributing to the revolution. You won't refuse, right?"

"Is there a salary?"

Yang Xiaotao rolled his eyes, and Mr. Wang pouted, "I'm already an honorary officer, what more money do you want. Two or three hundred a month, you don't think it's too much."

"You are really good at it, but you want to have sex for nothing."

"You brat, not everyone can have this honorary position."

Yang Xiaotao didn't believe it, and then smiled, "Uncle Wang, how about I give you an honorary officer position in the machinery factory, and then all the comrades here will come to our place to help?"

"It's not good. You are so evil-minded that you actually want to take advantage of us."

"Be good to each other."

The two of them were bickering, and Mr. Qian was smiling on the side. He was already used to their attitude.

"Director Ran, Mr. Yang."

Just as the two were bickering, Director Wang got up from his seat and ran over quickly. When he came to him, he shouted, "After calculation, we have given the parameters of a turbojet engine. If it can be realized, This final pursuit speed can exceed Mach 3, I wonder if Mr. Yang can do it."

Director Wang looked at Yang Xiaotao expectantly, and many people in the audience also looked at him.

Yang Xiaotao took the information from Director Wang's hand and looked at it, then thought about it in his mind, and finally nodded slowly.

"I can try."

"That's great."

Everyone below laughed.

Yang Xiaotao kept the design requirements in his pocket, and then followed Qian and the other two people out of the office.

"Come on, it's so easy to come here. I'll treat you to lunch."

Mr. Wang said proudly on the side, Mr. Qian behind him also nodded, "There are not many people who can make Mr. Wang take the initiative to treat guests."

"In that case, I really have to try it."

At noon, Yang Xiaotao had a very sumptuous lunch at the Seventh Machinery Department, and then drove back to the machinery factory.

Watching Yang Xiaotao drive away, Mr. Wang stood next to Mr. Qian and smoked a cigarette.

"Old Qian, are you serious?"

"What?"

"Didn't you say you would dig him up earlier?"

Mr. Qian turned back and walked back to the office, "Old Wang, what if I am serious?"

"This guy will be a good successor."

Wang Laozhang opened his mouth, then shook his head helplessly, "It's useless, Lao Chen won't let him go."

"And Lao Huang, don't ignore that guy. If he really gets serious, he will definitely interfere."

"And this guy Lao Qin is also a troublemaker."

Mr. Wang was scolding as he walked, knowing a few old brothers too well.

"Oh, so I'm just talking."

Mr. Qian also said helplessly.

Hearing this, Mr. Wang laughed and followed.

"By the way, you said he was the second one, then who was the first one?"

Mr. Wang asked from behind, but Mr. Qian walked into the office, and then heard a voice.

"My teacher."
