Chapter 2149 One Night's Work
At this moment, Yang Xiaotao's mind was filled with designs for missiles.
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 Hongqi missiles developed and produced by ourselves.
This model is similar to the Alliance's SAM model and consists of a boosting section and a sustaining section.
The boost phase uses solid fuel, while the sustain phase uses liquid fuel.
The current problem is that the solid motor cannot provide rapid propulsion, resulting in the missile being unable to follow the guidance after being launched.
Yang Xiaotao sat at the table and recalled seriously what Mr. Qian told him back then.
Looking at the design drawings on the table, Yang Xiaotao was sure that more energy was spent on it than on the gas turbine.
The reversal of the order just now also made Yang Xiaotao realize, could it be that the starting point was wrong?
Yang Xiaotao was refreshed, and he suddenly felt that he had found the crux of the problem.
If the order is changed and the turbojet engine is placed in the continuous section, that is to say, the ramjet engine is used to replace the liquid engine, what will be the effect?
This idea was out of control in Yang Xiaotao's mind.
“If that’s the case, this turbojet engine does not need a starter, which means that after obtaining the initial speed, this ramjet engine can directly use propellant and then use the oxygen in the air to work. "
"In this way, the structure will be more streamlined, and the cooperation with the solid motor will be closer..."
"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 got up and walked into the house.
He wants to sleep and rest.
In this way, you can keep your spirits up before going to the Seventh Machinery Department to discuss it.
The next day.
After Yang Xiaotao got up and had breakfast, he drove to the machinery factory.
The production of gas turbines is carried out by the first branch. As for the turbojet engine, there is no production task at the moment. We will arrange it when there is one.
Now with the support of the Sixth Machinery Department, the situation of the machinery factory is obviously much better.
Talents, materials, and resources don’t matter!
Being busy in the machinery factory until past ten o'clock, Yang Xiaotao told Liu Huaimin and drove to the Seventh Machinery Department with the drawings.
Seven Machinery Department.
Lao Wang came to the office early in the morning. Although Yang Xiaotao had promised him yesterday, eggs cannot be put in one basket.
What if Yang Xiaotao can’t do it?
What if you make a mistake and fail to achieve the expected goal?
This matter is too serious and we have to be cautious.
Thinking of this, Mr. Wang finished processing the documents on the table and walked to the office next to him with his hands behind his back.
In the room, Mr. Qian was busy on the table, with a pile of drawings placed in front of him.
“Old money, take a rest, don’t be tired now that you are old!”
Seeing Mr. Qian's tired look, Mr. Wang couldn't help but persuade him.
Mr. Qian turned a deaf ear and just lowered his head and waved his hand, letting Mr. Wang sit down by himself.
Seeing this, Mr. Wang sighed.
When the book is used, it will be less regrettable.
If you have the ability, it would be nice to be able to help.
Unfortunately, I am not a professional, so I can only scratch my head when faced with these problems.
Sitting aside, Mr. Wang made tea himself and prepared a cup for Mr. Qian. He brought it to the side and looked at the lines and numbers on the table.
Only one, he can see straight lines, arcs and corners.
There are also those numbers and labeled text.
But even if they are connected together, he doesn’t even know what they are for!
When Mr. Qian put down his pen, he took the tea cup from Mr. Wang's hand. The temperature was just right and he took a sip.
Seeing Mr. Wang's confusion, Mr. Qian explained, "In order for a missile to hit the target, it must not only have speed, but also precise navigation!"
"Navigation?"
“Yes!”
Mr. Qian put down his cup, then picked up the drawings and materials on the table.
"The most commonly used method now is the combination of radar navigation and infrared navigation."
"Within a certain range, after the target is discovered by the ground radar station, it continues to track the target and the launched missile."< br>
“The target’s location information is then transmitted to the receiver on the missile through radio signals, In this way, the missile adjusts its direction according to the signal, and then intercepts the target for kilometers! "
"After flying to a certain distance, the infrared tracks the temperature of the engine, quickly follows it, and then explodes, killing the aircraft. "
Mr. Wang nodded silently after hearing this. He had been in the Seventh Machinery Department and knew some of these things.
"So you want to improve the missile radar."
Mr. Wang asked tentatively.
Mr. Qian nodded, "I read the reports in Shanghai. The main reason is that there is no advantage in speed."
"But the missile can be fired out, and the inability to continuously and accurately track and pursue it is another factor. "
"The aircraft can be piloted by humans and dodge flexibly, but it is difficult for our missiles to make adjustments!"
"If we can increase our control over missiles!"
Having said this, 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 a red flag in these four directions, and when the target is close, launch it in the first two places. If these two missiles can achieve continuous and effective tracking, the enemy will The plane must make various evasive maneuvers to catch up in these two directions!"
"Then, launch from these two locations!"
"Then it will be launched in both directions! Our missiles, the result..."
"Bang!"
Mr. Wang stretched out his hand and gestured, "The plane will never run away!"
Mr. Qian nodded, "Yes, that's what it means!"
"Speed pursuit It doesn't matter if you don't get it, but you can't let the other party easily avoid it. This can also protect our target!"
Mr. Wang nodded, and then asked, "Have you found a way?" Mr. Qian shook his head, "You think I am a god, last night? I just thought, how could it be completed so quickly? ”
“Alas, it still takes time!”
Mr. Wang sighed, Mr. Qian didn’t care.
This is scientific research. Sometimes it is considered fast if it can be completed in one or two years!
Maybe, just like the research and development and manufacturing of aircraft, there will be no results at all within ten years.
"By the way, you went to see Yang Xiaotao yesterday?"
Mr. Wang nodded and sat back on his chair, "Stop talking, this guy went to a wedding and made me wait in front of the house for most of the day."< br>
“When you see me, hey, he’s the one who brings candies and pours tea. This kid knows how to be a good man!”
Mr. Wang smiled, and Mr. Qian picked up the water glass, "Where is his quality? It would be the same for anyone else!"
Mr. Wang was still proud, but he calmed down after a while, "I explained to him The situation has changed. I still had some time, but now that they are doing it with Lao Liuyi, my time will probably be reduced.”
"He also knew that the matter was urgent and promised to do it as soon as possible."
Mr. Qian took a deep breath after hearing this, "Oh, he is quite stressed about this matter!"
" It's for airplanes and it's for gas turbines, There is also a helicopter.”
“No matter how fast it is, how fast can it go?”
Mr. Wang bit his lips and sighed helplessly, “Yes, no matter how fast it can be, how fast can it go?” Where to go!”
"This kid, I can't say much, after all, it's not easy for everyone."
Mr. Qian nodded silently after hearing this, "Actually, this is our business, no wonder others."
“It’s just a matter of love to help us, no It’s your duty to help, there’s nothing wrong with it.”
Mr. Qian looked at Mr. Wang again, “Don’t be too picky!”
The latter smiled happily, “Don’t be like that. Look at me, am I an unreasonable person?”
"It's just that every family has its own scriptures that are difficult to recite!"
The room was silent for a moment, and Mr. Qian spoke again, "Everyone attaches great importance to this matter, and comrades also held their breath. If you are okay, , go for a walk down there, boost morale, and study this, I’m here!”
Mr. Wang nodded, this is his job.
"Don't worry, we won't be stingy this time. We will be rewarded and we will receive all the benefits we deserve. After all, we are also the seventh child, how can we be worse than a machine factory?"
< br> Mr. Qian smiled, picked up the pen and paper and prepared to look at it again. Mr. Wang was about to go out, but he heard Mr. Qian lowering his head and said, "Also, you, don't go to Lao Ran all day long, it won't put any pressure on him." Small! ”
After hearing this, Mr. Wang immediately turned around and glared, "Old Qian, with all conscience, I really don't mean that!"
"Yes, you don't mean that, but you still don't know about Lao Ran? In his heart It’s just a pretense, but he can feel it even if you don’t say it.”
< br>"Let me tell you, this guy brought his people with him for a piece of data..."
Qian Laozheng was talking, and suddenly there was a knock on the door, and then he saw the office director. Comrade Lao Ran opened the door and walked in, followed by Yang Xiaotao.
Both of them shut up at the same time.
I was talking about these two people just now, why did they both show up in the blink of an eye?
Ran's father didn't see the embarrassment on their faces, so he walked in quickly 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 speechless holding the design drawing in the back.
He drove to the Seventh Machinery Department. As soon as he entered the gate, he met Ran's father.
The two met and chatted for a few words. Yang Xiaotao explained his idea. Then Ran's father stood there in silence for a while and immediately rushed over with Yang Xiaotao.
Ran's father looked at Yang Xiaotao, and Mr. Qian and Mr. Wang also looked over.
Yang Xiaotao first greeted Mr. Wang, then came to Mr. Qian unhurriedly and put the drawings on the table.
"Chief, I had some ideas when I was researching last night. I would like to discuss with you whether it is necessary to study it."
Yang Xiaotao did not dare to say it to death. He just made a suggestion, which may not be enough. Really useful.
Mr. Wang and Father Ran immediately came over 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!"
"Okay!"
Yang Xiaotao took a deep breath, and then Said, "I understand that our current missiles use a combination of solid engines and liquid engines!"
"Previously you said that you want to increase the initial launch speed, so you are planning to use a turbojet engine to replace the solid engine engine to speed up ”
Mr. Qian nodded, "Yes, that's true."
"But I found an important problem during the design!"
"That is that the ignition of the turbojet engine requires a starter, and the turbine There is also a problem with the connection between the jet and the liquid engine, which may hinder the work of the liquid engine..."
As Yang Xiaotao spoke, he pulled out the engine drawings he designed, while Mr. Qian looked at it carefully.
Ran's father and Mr. Wang also came forward, but the former could understand it somewhat, but the latter was just like "looking at the pictures and talking", he couldn't understand it at all!
After a while, Mr. Qian didn't understand what was going on, and then looked at Yang Xiaotao.
Yang Xiaotao understood and continued, "My opinion is to retain the original solid engine, and then replace the liquid engine with a turbojet engine."
After the words fell, Qian Lao Teng's words He stood up from his seat, clapped his hands on his chest, and thought while walking.
He even said the words solid engine, liquid engine, and turbojet engine.
Ran's father on the side was also calculating in his mind. He heard Yang Xiaotao say before that he didn't think carefully.
Yang Xiaotao was waiting quietly on the side. He had already done what he could do. Whether it would succeed or not would depend on these two!
As for Mr. Wang, he understands everything now and looks confused.
But seeing Yang Xiaotao standing aside, he hurriedly picked up the tea cup and came to him with a kind face, "Xiao Tao, come on, come on, have a taste of the tea from our Seventh Machinery Department!"
Yang Xiaotao quickly took the tea cup. Seeing Mr. Wang's enthusiastic look, he always felt a little uncomfortable.
He was still used to Mr. Wang's fussy attitude.
"You look like you haven't slept, okay? You have worked so hard for us!"
"Don't worry, we will remember your contribution! Your contribution will never be lost. !”
Mr. Wang showed a caring attitude that would never let you suffer, which made Yang Xiaotao a little overwhelmed.
“Well, Chief, it’s not too troublesome actually. I just thought about it last night!”
Hearing this, Mr. Wang was startled, “This is what you came up with last night. ?”
"Well, I couldn't sleep, so I thought about it for a while, and then..."
"Oh, Chief, what's wrong with you?"
"Don't scare me~"
