In 1978, I was admitted to Harbin Institute of Technology

Chapter 97: Rocket and missile technology is not much different from fighter aircraft technology? Do you really understand?

There are no supporting facilities, and the basic materials and technologies need to be developed from the most basic level.

Not to mention the stealth coating and stronger and lighter composite materials used by Twenty Master.

To Xie Wei, even the Twentyth Master was behind.

Before Xie Wei came into this world, the sweetheart of the Air Force was the J-50, and the J-20 had long become Mrs. Niu.

At that time, at every air show, not only could visitors touch Twenty Master up close, but ground staff also roughly cleaned him with a mop in public, not caring at all whether it would break his skin.

The HNA's J-35 was treated the same way as the Twenty-year-old, becoming a Type 35 girl with a big belly and a lot of stuff.

"You should work with the relevant teachers in the school to build the framework first. Our fighter jet project development is the same as the electromechanical department, starting with theory. The school's funds are limited, and the project cannot be led by 601 or 611, otherwise it will become us providing funds for them to do it."

Li Rui said to Xie Wei.

Professional introductions should be heard by professionals.

"Is the school planning to independently develop a fighter jet?"

The principal's words made Xie Wei a little stunned. Before he could get an answer, Xie Wei asked another key question: "Does the school have a research and development team for fighter aircraft technology?"

According to his understanding, the school currently does not have any aviation major.

If we have to say there is a connection, materials, aerodynamics and other things may be related.

"It didn't happen before, but it does happen now. You have a lot of things to do, so you should be a consultant. If you have any errands, let Yuan Zhenyue do them. He will be your assistant."

"..."

Xie Wei looked at Li Rui in confusion.

Now there is!

Act as a consultant yourself.

Yuan Zhenyue was also dumbfounded, staring at the principal blankly: You just asked me to stop Xie Wei from running away, and now you ask me to be Xie Wei's assistant?

This was probably to arrange himself to be next to Xie Wei so that Xie Wei could vent his anger!
"Don't worry, your consultant allowance will be there."

Xie Wei almost went berserk: Why the hell should I care about this consultant allowance?

But Li Rui didn't give Xie Wei any chance to attack.

"Tomorrow morning, the relevant personnel will go to the small conference room according to the previously discussed list and groupings. Xie Wei will assign them tasks. We will discuss this together after the people from 601 arrive."

Principal Li wanted to slam the table to make the final decision.

When I raised my hand, I found that the bodies on the table were already scattered all over the floor.

"It's settled! It's getting late, so I won't be inviting you all to dinner."

"..."

The last sentence made the leaders who just thought the principal was reliable roll their eyes.

"Wait, Principal, I don't know anything about this. You want me to assign tasks to them..."

Xie Wei finally reacted.

Isn't it like showing off one's proficiency in front of an expert to fool professional technicians?

Don't you think you're not dying fast enough?

In particular, the professional team also includes Shi Ye’s father and Mr. Zhu, who was in charge of the country’s advanced pulse Doppler radar in the 1980s.

How to fool?

"Just do it your way. Who would know how to do it right from the start? Remember, we have only one goal: don't let them leave after they come. Don't worry, I have your strong backing!"

Li Rui said this irresponsibly, patted Xie Wei on the shoulder, and left the office quickly without looking back.

I was afraid that Xie Wei would object.

Without waiting for Xie Wei to speak, several other school leaders all looked at him with an "I'm optimistic about you" expression, patted Xie Wei on the shoulder with a smile, and filed out one after another.

"Student Xie Wei, why don't you go back and rest first? Tomorrow morning at eight o'clock..."

After a while, Yuan Zhenyue finally mustered up the courage, took two steps forward, kept his distance, and quietly reminded Xie Wei who was still in a daze.

He was afraid that Xie Wei would beat him.

When Li Rui went to find Xie Wei in the office, he reminded Yuan Zhenyue to block the door after Xie Wei entered the office to prevent Xie Wei from running away.

Knowing that Xie Wei was a favorite of the principal and other school leaders and that he could not afford to offend him, Yuan Zhenyue made it clear that he would not do it.

However, Principal Li asked him with a straight face: "If you can't afford to offend him, can you afford to offend me?"

then……

Xie Wei came back to his senses and gave Yuan Zhenyue a cold look.

The cold look made Yuan Zhenyue take two steps back.

"Well, monitor Xie, it's not me who wants to stop you, it's the principal's order."

Assistant Yuan decisively betrayed the principal.

There is no way but to sell out.

It would be a waste of Xie Wei's beating. The principal and other school leaders might even ask him to apologize to Xie Wei.

Ignoring Yuan Zhenyue, Xie Wei walked towards the dormitory while thinking about how to fool the country's top experts.

There are plans, but they are too far in advance.

The preparations were not done well.

Xie Wei didn't attack him, but Yuan Zhenyue felt even more uneasy.

He heard the principal's analysis.

Xie Wei had no time to pay attention to Yuan Zhenyue's thoughts.

Although Li Rui irresponsibly threw a few random things to him, Xie Wei didn't intend to deal with them carelessly.

I carefully organized in my mind the advanced fighter aircraft technologies that I had learned.

The basic principles and directions are still understood.

After returning to the dormitory, the other roommates had not returned yet, so Xie Wei simply began to list the technologies needed for advanced fighter jets in his homework book.

You propose the direction yourself, and professional teams such as 601 and 611 are responsible for its implementation.

Early the next morning, when Xie Wei had just returned to the dormitory after running, Yuan Zhenyue, with red eyes, appeared in front of Xie Wei with a large enamel soup bowl full of rolled noodles and a fried egg on top.

"Assistant Yuan, what are you doing?"

There was a layer of oil floating on the bowl of noodles, so it was not the noodles from the cafeteria.

The rich aroma mixed with lard and fried eggs made Xie Wei's saliva secretion accelerate, and he swallowed unconsciously.

"Didn't the principal ask me to be your assistant? I thought since you're busy, bringing the food to you would save you time."

Yuan Zhenyue answered with a smile.

I couldn't sleep the whole night last night: I was afraid that an old silver coin like Xie Wei, who was deep-minded, would plot against me, and I wouldn't even know how I died.

Yuan Zhenyue knew from previous experience that the people who take direct action are not to be feared, but the ones who play tricks are to be feared.

Killings are made without any blood.

After thinking about it for a whole night, Yuan Zhenyue couldn't find any other solution. He remembered that Xie Wei was delicious, and if Xie Wei ate his food, he would not seek revenge on him.

When I was the principal's assistant, I was studying the people the principal cared about, so naturally I knew Xie Wei.

I got up early in the morning to mix and cook noodles...

"Isn't that necessary?"

"The principal knows you are busy, so he asked me to take care of your logistics."

Yuan Zhenyue awkwardly pulled the principal out to take the blame.

"You were tricked by that old guy! I don't need you to do any logistical work at all."

Xie Wei was speechless.

I really want to take good care of myself and find myself a wife, but I don’t want one from the Northeast.

Looking at Yuan Zhenyue, Xie Wei couldn't help but sigh that it's not easy to be an assistant these days.

Before, Wu Tao had to help kill fish and cook; Wang Zheng had to do everything from lighting the stove to sharpening knives.

Yuan Zhenyue nodded hurriedly: If the old principal hadn't asked me to stop Xie Wei, I wouldn't have been so scared that I couldn't sleep all night.

Previous experiences forced Yuan Zhenyue to take Xie Wei, an old silver coin with a deep mind, seriously.

Xie Wei thought that since the principal had paid for it, it shouldn’t be wasted, especially the fried egg noodles that contained so much lard.

The only thing missing is the green leafy vegetables and green onions that are used to garnish the noodles made by my mother Liu Mei.

When asked if Yuan Zhenyue had eaten, the latter hurriedly said that he had already eaten.

Xie Wei was no longer polite. He took the lunch box and picked up the fried egg from the soup bowl and put it into his own lunch box.

Xie Wei would have thought that this was made by Yuan Zhenyue using the oil, eggs and flour that he saved by living frugally!
"Old Yuan, from now on you should focus on the fighter jet project. The old principal is not a good person!"

While eating the greasy noodles, Xie Wei felt that he should give Yuan Zhenyue some advice.

The fighter project team lacks managers.

Although it was a bit unkind of Yuan Zhenyue to stop him last night, Xie Wei knew that he would not dare to do so without Li Rui's order.

Just show the other party a clear way forward.

Third generation aircraft!
Even if we do preliminary research now, when the Air Force's third-generation aircraft project is officially launched, the experienced Yuan Zhenyue will be able to take on management work in the project and leave Li Rui, the insidious and irresponsible old man.

What's more, managers who are familiar with technology and have experience can only bring benefits and no harm to any project.

Hearing what Xie Wei said, Yuan Zhenyue could only smile awkwardly and did not dare to speak.

I felt relieved.

"Hey, it smells so good!"

Just when Yuan Zhenyue didn't know how to answer Xie Wei's words, Yao Xinwei's voice came from outside.

"Have you eaten yet? There are noodles here... The old principal treated us, so don't waste them if you don't eat them."

Xie Wei pointed at the soup bowls on the table which were not much smaller and said to Yao Xinwei.

"Squad leader, what big project are you working on?"

Yao Xinwei swallowed his saliva and asked in surprise, "Do I have a chance to participate in the project this time?"

Xie Wei, who was holding a noodle in his mouth, looked at Yao Xinwei in surprise.

For Yao Xinwei, life without participating in projects is very comfortable.

Unlike students who participate in the project, you don’t have to not only complete your studies, but also take time to self-study the various professional knowledge required to participate in the project.

Several students in the dormitory who were participating in the project usually did not sleep for more than five hours.

"Alas, today is different from the past. The rich man's life is not easy either."

Yao Xinwei sighed.

Starting half a month ago, students in the experimental class who did not participate in the project had far more homework than those who participated in the project.

The teachers said: You have more time than the students who participated in the project, so you should lay a solid foundation and make greater contributions to the modernization of our motherland!
It’s better to join the project.

At least, I still have half a pound of food coupons and a 20-cent subsidy every day!

Xie Wei quickly swallowed the noodles and looked at Yao Xinwei.

Yao Xinwei, who comes from a well-off family, has never been very enthusiastic about projects.

"Squad leader, I want to improve!"

Yao Xinwei looked serious.

If he didn't know the other person, Xie Wei would really believe it.

If it were earlier, this kid would have been regarded as a typical reactionary!
I still want to make progress!
Xie Wei pouted and looked at Yao Xinwei with a playful look. Yao Xinwei had no choice but to tell the truth with a sad face: "My classmates are getting subsidies for participating in the project. I wrote to my parents and told them that my dad cut my living allowance in half..."

really!

This kid is still not the kind of person who actively pursues progress.

I guess his parents knew what kind of guy he was, so they directly took advantage of him and forced Yao Xinwei to make progress.

Pity the parents of the world.

"Okay, there will be a new project soon, and I'll reserve a spot for you then. Fifth brother, eat the noodles first, they'll get cold soon."

Xie Wei reminded Yao Xinwei.

He had finished eating. Instead of squeezing the lunch box with detergent to dilute the remaining oil as he had done before, he followed Zhang Jingyan and others and first drank the remaining oil with hot water, and then washed the lunch box with detergent.

Yao Xinwei took his rice bowl, picked up a few noodles from it, and poured a lot of water from the kettle...

This surprised Xie Wei even more.

Is the rich man's life reduced to having to rely on water to fill his stomach?

"I'm saving it for my elder brother and the others. They'll be back soon. Usually they don't want to eat noodles..."

Yao Xinwei said.

It seems that being hungry can make people mature and sensible.

Without interfering with Yao Xinwei, Xie Wei poured half a lunch box of hot water from the thermos and put some detergent in it.

The rich scent of jasmine soon spread.

"Hey, the scent of jasmine! Monitor, are dishwashing liquids scented now?"

Yao Xinwei, who was eating noodles one by one, smelled the fragrance and asked in surprise.

"It was done by the eldest and second brother."

Xie Wei explained with a smile.

After refusing Yuan Zhenyue's offer to help him wash the lunch box, Xie Wei went straight to the washroom.

When I came back after washing the lunch boxes, the others had also returned.

Each person had a large bowl of water and a few sparse noodles.

Xie Wei shook his head when he saw this.

I thought that it was the principal who gave the money, and the old guy cheated me, so what was wrong with me and my roommates eating a little of his food?
He immediately looked at Yuan Zhenyue and said, "Old Yuan, how about sending more next time?"

"..."

Yuan Zhenyue's mouth twitched as he looked at all the men in the dormitory. How could everyone be fed with less than three to five kilograms of noodles for a meal?

If it was really given by the principal, it’s nothing.

The key is to pay for it yourself.

Agree it. The supplies you have will be gone in just a few meals and you will starve to death.

If he didn't agree, he was afraid that Xie Wei, the old silver coin, would cheat him.

For a moment, Yuan Zhen became more and more embarrassed.

"Squad leader, don't do that! We just need to follow you occasionally to get some benefits."

Seeing Yuan Zhenyue's expression, Zhang Jingyan said hurriedly.

"Yes, the principal is not a wealthy landlord. I heard that he didn't hand over his salary and was kicked out by his wife..."

Yao Xinwei added.

This kid even knows this news?
Thinking about how Du Guowang bullied Li Rui and was kicked out by his wife on the day he just came back, the news should be true.

"That's fine."

Yuan Zhenyue breathed a sigh of relief.

I raised my wrist to check the time. It was already seven forty, very close to the eight o'clock time when I had to notify relevant personnel to attend the meeting.

"Thank you, squad leader. The others are already waiting for you in the conference room."

After saying hello to his roommates, Xie Wei and Yuan Zhenyue left the dormitory.

"Brothers, the monitor has agreed to let me participate in the project. Please give me some advice. Which project is suitable for me?"

As soon as Xie Wei left, Yao Xinwei asked several people.

In the dormitory, Tang Long and Zhang Jingyan were in the chemistry laboratory; Feng Ke joined the computer project; Li Chuangxin was in the newly established radio project. Only Yao Xinwei did not participate in the project.

Even without a living allowance from his family, Yao Xinwei had long wanted to participate in the project.

Everyone around me is pursuing progress, but I am alone. I always feel that everyone looks at me with contempt.

"Don't you want to study computers?"

Feng Ke looked at Yao Xinwei in confusion, "Tell the monitor that you are going to the computer project. Otherwise, let's tell the monitor that you are going to the computer project, and I will wait for the opportunity to go to the rocket..."

Feng Ke doesn't like computer technology.

The Rockets are more attractive.

"Can it be done?"

Yao Xinwei asked.

"No problem. I want to go to the Metal Materials Research Laboratory, and the monitor agreed. Lao Yao, you have to think carefully. Your family wants you to work on rockets, don't let your parents cut off all your living expenses..."

Zhang Jingyan reminded Yao Xinwei.

"Let it go! I don't want to live my whole life according to their plans! Besides, don't rockets also need computers? I told them that they didn't need computers for rockets. They are experts in this field and they will definitely not doubt it."

Yao Xinwei grinned.

"..."

······
"... Under the current circumstances, it is too late to subdivide the project. We will divide the existing personnel into four groups: pneumatics, control, power, and avionics. Let's build the framework first..."

In the small conference room, Xie Wei said this after understanding the situation.

Among the more than ten key personnel selected from the schools, none of them had experience in developing fighter-related technologies.

You can only treat a dead horse as a living horse doctor.

The only thing to be thankful for is that we are all involved in aerospace and have similar theoretical foundations.

"Student Xie Wei, how will the specific tasks be assigned?"

Fei Tianxiang, who studies rocket control technology, asked Xie Wei.

The school transferred him to work on fighter jet control systems, but he was extremely reluctant.

But the principal said that the project is related to the recovery of the Department of Aeronautics and Astronautics, plus fighter control systems, sensors, control design, etc., aerospace rockets and missiles are also needed.

But Fei Tianxiang had no idea how to start.

Fei Tianxiang doesn't care who arranges the work.

He cares about when and how he gets to work.

"Teacher Fei, please take charge of the control project. At present, we have proposed technical standards. The core of the entire control system is a sensor group composed of high-precision balanced gyroscopes, inertial measurement devices such as accelerometers, and atmospheric measurement devices such as angle of attack sensors. High-performance data processors are used to process various signals... In the early stage, we will start with analog signals, and the subsequent research direction will be digital signals..."

Last night, Xie Wei conducted a systematic analysis of what he had mastered and the current basic technologies.

In his homework book, he arranged everyone directly according to the four categories he proposed.

He just flipped through the homework book and explained it to everyone as planned.

At this moment, I am too lazy to hide.

If I hide it, won't that irresponsible old man Li Rui cheat me?

Since I can't resist.

Take the initiative to enjoy yourself, because then it will be Li Rui and the school leaders who will be in trouble: the stronger your ability is, the more afraid the school will be that you will be snatched away by other units.

"In terms of radar, we will first solve the problem of miniaturization of 204 radar. While digesting the basics, we will further increase the signal transmission channels and data interfaces. We will integrate weapons and equipment into the radar system, so that the radar not only has detection and tracking functions, but also needs to have aiming, locking, and attack functions. Detection means tracking, tracking means locking, and locking means attack. Everything is centered on the central data processor..."

"The reason why the fire control radar system and the flight control system are listed separately is that these two are more critical and require too many technological breakthroughs."

"Communication systems, positioning and navigation systems, environmental control, power supplies, instruments, etc. need to be upgraded according to demand. For example, if an analog or digital control system is used, it is impossible to use ordinary mechanical instruments to respond to parameters, right?"

When everyone heard this, a smile appeared on their faces.

Those selected by the school were not familiar with fighter aircraft technology. Now that what Xie Wei introduced had not deviated too much from the original technical research, their worries were gone.

Fei Tianxiang, in particular, breathed a sigh of relief.

Rockets and missiles also need these basic components, such as various sensors, central data processors, servos, and electrical transmission lines, and the basic theories are not much different.

"Student Xie Wei, what about the power system? We can't just three people develop a high-thrust turbofan engine..."

Wu Haowen, who was transferred from the rocket power room, saw that Xie Wei had assigned tasks to several other groups.

There has been no work on the power group, and I can't help but get anxious.

As a researcher in rocket propulsion, he knew very well that aircraft engines were completely different from rocket engines.

Rocket engines are relatively easier: for an intercontinental strategic missile with a range of tens of thousands of kilometers, the engine only works for tens of minutes. No matter how high the operating temperature of the engine's tail nozzle is, as long as the engine keeps working until it reaches its destination, it will be fine.

The fighter jet engine is not working.

Service life is a hard indicator.

The flame temperature of the tail nozzle is thousands of degrees Celsius, and it needs to continue running for hundreds or even thousands of hours!
Not only does it require a long service life, it also needs to provide great thrust to the fighter.

"The engine is of utmost importance. So it is put last. Since we need to consider the low-altitude performance of the fighter and also have to have high-altitude speed, the only solution can only be a military afterburner turbofan engine with high thrust and low bypass ratio..."

“We’ve only ever worked with rocket engines before.”

Wu Haowen frowned and looked at Xie Wei.

He did not doubt whether what Xie Wei said could be realized, but he did not know it at the moment.

If Wu Haowen knew that Xie Wei only knew the basics in theory, he would not have such an attitude.

“This is actually very simple…”

When Yuan Zhenyue, who was taking notes quickly, heard Xie Wei say it was simple, the corner of his mouth twitched.

He wrote down everything Xie Wei said.

But his mind went blank.

Is it simple?

What is bypass ratio?
What is high thrust?
Why is it a military afterburning turbofan engine again?

Are these talking about the same thing?
"Just think of the rocket engine as the core engine of the turbofan engine. However, rocket and missile engines do not need pressurized and accelerated external air to provide thrust. Instead, they use the violent reaction between propellant fuel, catalyst, and oxidizer to provide thrust..."

"So it seems to be relatively simple, right?"

After hearing what Xie Wei said, Wu Haowen felt that it seemed to be quite simple indeed.

"The direction of the power team is to develop a high-thrust turbofan engine with a thrust-to-weight ratio of more than 8... In order to achieve such a thrust-to-weight ratio, based on the current technical foundation of the WS-6, the turbofan structure of the internal combustion engine needs to be improved, the materials need to be improved, and the temperature of the front combustion chamber needs to be increased to more than 1400°C. After the afterburner is turned on, the engine needs to withstand a high temperature of 1800°C."

"..."

Wu Haowen, who thought it seemed very simple just now, was dumbfounded.

But Xie Wei's next words made him want to quit the research on fighter aircraft technology: "Compared to rocket engines that need to withstand temperatures over 3000℃, turbofan engines with afterburner only need to withstand temperatures of 1800℃ and huge pressure for a short time..."

Wu Haowen opened his eyes wide and wanted to swear at Xie Wei: How the hell can this be the same?
It is not a problem at all to discard a turbofan engine if it is powered up.

Rocket engines can withstand temperatures over 3000°C. This problem can be solved by adding ablative cooling materials to the engine that can quickly take away the high temperature, adding a cooling system, or adding a thermal insulation coating to the tail nozzle.

This is a turbofan engine that needs to be reused!

After the combustion chamber instantly reaches 1800°C, it has to continue working under different temperature conditions for hundreds of hours!

Simple?
How could this guy say that?
Does he really understand?
