Chapter 2149 One Night's Work

At this moment, many designs of missiles emerged in Yang Xiaotao's mind.

Learn about the current missile situation from Ran's father.

Because of the break with the alliance, the missiles currently used in the country are all Hongqi missiles developed and produced by the country itself.

This model is similar to the Alliance's Sam model, consisting of a boost section and a sustain section.

The boost phase uses solid fuel, while the continuation phase uses liquid fuel.

The problem now is that the solid engine cannot provide rapid propulsion, which results in the missile being unable to follow the guidance and keep up with the target after it is launched.

Yang Xiaotao sat at the table and recalled carefully. This was what Mr. Qian had said to him at the beginning.

But looking at the design drawings on the table, Yang Xiaotao was sure that more energy was spent on this than on the gas turbine.

The reversal of order just now also made Yang Xiaotao realize that maybe the starting point was wrong?
Yang Xiaotao's spirits lifted. He suddenly felt that he might have found the crux of the problem.

If we change the order and put the turbojet engine in the continuous section, that is, use the ramjet engine instead of the liquid engine, what will be the effect?

This idea got out of control in Yang Xiaotao's mind.

"If that's the case, this turbojet engine doesn't need a starter, which means that after gaining initial velocity, this ramjet engine can directly use propellant and then use oxygen in the air to work."

"This will make the structure more streamlined and more closely coordinated with the solid engine..."

"In this case, the speed achieved should not be worse than that of a liquid engine."

Yang Xiaotao's eyes narrowed slightly.

He doesn't know if it's possible without experimenting, but this is a research direction.

Then he stood up and walked into the house.

He wants to sleep and rest.

Only by keeping your spirits up can you go to the Seventh Ministry of Machine Building to discuss things.

the next day.

After getting up and having breakfast, Yang Xiaotao drove to the machinery factory.

The production of gas turbines is under the charge of Branch 1. As for turbojet engines, there is no production task at the moment and it will be arranged when there is one.

Now with the support of the Sixth Ministry of Machine Building, the situation of the machinery factory has obviously improved a lot.

Talent, materials and resources no longer need to be tight-fisted!

After working at the machinery factory until after ten o'clock, Yang Xiaotao said goodbye to Liu Huaimin and drove to the Seventh Ministry of Machine Building with the drawings.

Seventh Machinery Department.

Mr. Wang came to the office early in the morning. Although Yang Xiaotao had promised him yesterday, he should not put all his eggs in one basket.

What if Yang Xiaotao can’t do it?

What if we make mistakes and fail to achieve the expected goals?
This matter is too serious and we have to be cautious.

Thinking of this, Mr. Wang finished processing the documents on his desk, then went to the office nearby with his hands behind his back.

In the room, Mr. Qian was busy working on the table with a pile of drawings in front of him.

"Old Qian, take a break. Don't get tired at your age!"

Seeing how exhausted Mr. Qian looked, Mr. Wang couldn't help but persuade him.

However, Mr. Qian turned a deaf ear to him, just lowered his head and waved his hand, asking Mr. Wang to sit down by himself.

Seeing this, Mr. Wang sighed.

You only regret not having read enough books when you need them.

If you have the ability, it would be great if you could lend a hand.

Unfortunately, I am not a professional, so when faced with these problems, I can only scratch my head and feel a headache.

Mr. Wang, who was sitting nearby, made tea himself and also prepared a cup for Mr. Qian. He brought it to the side and looked at the lines and numbers on the table.

Even if it is a single line, he can tell what are the straight lines, arcs and corners.

And there are those numbers and marked text.

But when they are connected together, he doesn’t even know what they are for!

After Mr. Qian put down his pen, he took the teacup from Mr. Wang's hand. The temperature was just right, so he took a sip.

Seeing that Mr. Wang was puzzled, Mr. Qian explained, "In order for a missile to hit its target, it not only needs speed, but also precise navigation!"

"navigation?"

"Correct!"

Mr. Qian put down the cup and picked up the drawings on the table.

"The most commonly used method now is a combination of radar navigation and infrared navigation."

"Within a certain range, after the target is discovered by the ground radar station, it will continue to track the target and the missiles launched."

"Then the target's location information is transmitted to the receiver on the missile via radio signals, so that the missile adjusts its direction according to the signal and then intercepts the target at a distance!"

"After it flies to a certain distance, the infrared tracks the temperature of the engine, quickly catches up and then explodes, killing the aircraft."

After listening to this, Mr. Wang nodded silently. He had been exposed to many things in the Seventh Ministry of Machine Building and knew a little about these things.

"So you need to improve the missile radar."

Mr. Wang asked tentatively.

Mr. Qian nodded. "I read the report from Shanghai. The main problem is that they don't have an advantage in speed."

"But once the missile is launched, it cannot be tracked and pursued accurately."

"Aircraft can be piloted by humans and can dodge flexibly, but it is difficult for our missiles to make adjustments!"

"If we can increase our control over missiles!"

Having said that, Mr. Qian took out a piece of paper from the side and drew a circle on each of the four corners with a pencil.

"Look, if we put up a red flag at each of these four locations, and when the target approaches, we launch missiles from the first two locations. If these two missiles can continue to track the target effectively, the enemy aircraft will have to make all kinds of evasive moves, causing them to chase in these two directions!"

"Then, launch them from these two locations!"

"And then there are our missiles all around us, what will happen..."

"boom!"

Mr. Wang gestured with his hand, "The plane will definitely not escape!"

Mr. Qian nodded, "Yes, that's what I mean!"

"It doesn't matter if we can't catch up with them in speed, but we can't let them dodge easily. This way we can also protect our target!"

Elder Wang nodded, and then asked, "Have you found a solution?" Elder Qian shook his head, "Do you think I'm a god? I just thought of it last night. How can I complete it so quickly?"

"Alas, it still takes time!"

Mr. Wang sighed, but Mr. Qian didn't care.

This is scientific research. Sometimes, completing it in one or two years is considered fast!

If things go wrong, it will be just like the research, development and manufacturing of aircraft. It will take at least ten years to achieve any results.

"By the way, did you go to see Yang Xiaotao yesterday?"

Old Wang nodded and sat back in his chair. "Stop talking. This guy went to attend a wedding and made me wait at the door for most of the day."

"See me, hehe, that's the one who brings candy and pours tea, this kid knows how to behave!"

Mr. Wang smiled, and Mr. Qian picked up the water glass. "Their quality is there, it doesn't matter who goes there!"

Old Wang was still feeling proud, but soon calmed down. "I explained the situation to him. We originally had some extra time, but now that they're dealing with Old Six, I think the time will be reduced!"

"He also knew the matter was urgent and promised to do it as soon as possible."

After hearing this, Mr. Qian took a deep breath and said, "Ah, this matter has put a lot of pressure on him!"

"There are airplanes, gas turbines, and a helicopter."

"How fast can it be?"

Old Wang bit his lip and finally sighed helplessly, "Yeah, no matter how fast it is, how fast can it be!"

"I can't say much about this kid. After all, it's not easy for everyone."

After hearing this, Mr. Qian nodded silently, "Actually, this is originally our business, so we can't blame them."

"Helping us is a favor, not helping is a duty, there is nothing wrong with that."

Mr. Qian glanced at Mr. Wang again and said, "Don't be so picky!"

The latter smiled happily, "Don't look at me like that, am I an unreasonable person?"

"But every family has its own problems!"

There was silence in the room for a moment, and then Mr. Qian spoke again, "Everyone takes this matter very seriously, and the comrades are also holding their breath. If you have nothing to do, go downstairs and boost morale. I'll be there to study this!"

Mr. Wang nodded, this was his job.

"Don't worry, we won't be stingy this time. We will reward you accordingly and provide you with all the benefits you deserve. After all, we are the seventh in command. How can we be worse than the machinery factory?"

Old Qian smiled, picked up a pen and paper and prepared to take another look. When Old Wang was about to leave, he heard Old Qian lower his head and say, "Also, you, don't go looking for Old Ran all day long. This puts a lot of pressure on him!"

After hearing this, Mr. Wang immediately turned around and glared, "Old Qian, I swear to God, I really didn't mean that!"

"Yes, you didn't mean that, but don't you know who Old Ran is? He has something on his mind, and he can sense it even if you don't say it."

"Let me tell you, this guy brought his men with him just for a piece of data..."

As Mr. Qian was speaking, there was a knock on the door. Then he saw the office director, Comrade Lao Ran, push open the door and walk in, followed by Yang Xiaotao.

They both shut up at the same time.

I was just talking about these two people, how come they are here in the blink of an eye?
Father Ran didn't notice the embarrassment on the two's faces, and hurriedly walked in and said, "Chief, Xiao Tao is here. He has a new idea. I think we can try it."

After saying that, he looked at Yang Xiaotao.

Yang Xiaotao was holding the design drawings in the back, speechless.

He drove to the Seventh Ministry of Machine Building and just as he entered the gate, he ran into Ran's father.

The two met and chatted for a few words. Yang Xiaotao told him his idea, and then Ran's father stood there in a daze for a while, and immediately brought Yang Xiaotao over.

Father Ran looked at Yang Xiaotao, and Elder Qian and Elder Wang also looked over.

Yang Xiaotao first greeted Mr. Wang, then walked slowly to Mr. Qian and placed the drawings on the table.

"Commander, I had an idea while researching last night, and I wanted to discuss it with you to see if it's necessary to research it."

Yang Xiaotao didn't dare to say anything definite. He just made a suggestion, which might not be really useful.

Old Wang and Ran's father came over immediately and listened to what Yang Xiaotao said.

Mr. Qian also put the other drawings on the table aside, and then said seriously, "You say!"

"it is good!"

Yang Xiaotao took a deep breath and then said, "I understand that our current missiles use a combination of solid and liquid engines!"

"You said earlier that you wanted to increase the initial launch velocity, so you planned to use a turbojet engine instead of a solid engine to increase the speed!"

Mr. Qian nodded, "Yes, that's right."

“But I discovered an important problem when I was designing it!”

"That is, the ignition of the turbojet engine requires a starter, and there are also problems with the connection between the turbojet and the liquid engine. If it is not handled properly, it may hinder the operation of the liquid engine..."

As Yang Xiaotao spoke, he took out the drawings of the engine he designed, and Mr. Qian watched carefully beside him.

Father Ran and Old Man Wang also came forward, but the former could understand it a little bit, but the latter was just like the "picture talk" just now, he couldn't understand it at all!
After a while, Mr. Qian still didn't understand what was going on, and then looked at Yang Xiaotao.

Yang Xiaotao understood and continued, "My opinion is to keep the original solid engine and replace the liquid engine with a turbojet engine."

After he finished speaking, Qian Laoteng stood up from his chair, patted his chest with his hands, and thought as he walked.

He was even saying words like solid engine, liquid engine, and turbojet engine.

Ran's father, who was standing by, was also calculating in his mind. He had not thought carefully about what Yang Xiaotao said before.

Yang Xiaotao was waiting quietly on the side. He had done what he could. Whether it would succeed or not depended on these two!

As for Mr. Wang, he now understood the situation and looked confused.

But seeing Yang Xiaotao standing nearby, he quickly picked up the teacup and came forward with a friendly look on his face, "Xiaotao, come here, try the tea from our Seventh Machine Department!"

Yang Xiaotao quickly took the teacup. Seeing Mr. Wang's enthusiastic look, he felt a little uncomfortable.

He was still used to Mr. Wang's fussy attitude.

"You look like you didn't sleep well. You must have been worried about us!"

"Don't worry, we will remember your contribution! You will definitely not be left out of the credit!"

Mr. Wang looked caring and would never let you suffer any loss, which made Yang Xiaotao a little at a loss.

"Well, Chief, it's not that difficult, I just thought about it last night!"

Hearing this, Mr. Wang was startled, "Did you come up with this last night?"

"Well, I couldn't sleep, so I thought about it for a while, and then..."

"Hey, Chief, what's wrong with you?"

"Don't scare me~"
