The Red Era, the Opening University Speech

Chapter 435 Integration 18w
You may not have to go all out to check it, but you definitely have to check it.

Other things can be concealed, but military mountain bikes cannot be concealed and can be easily detected.

Since the suspects had already been identified by the intelligence agencies of both sides, there was no need for him to jump in again.

Here, when Li Mu's thoughts were turning rapidly.

After getting his confirmation, Yang Ying couldn't help but cheer:
"Great!"

He knew that the higher-ups would never treat a scientist like Li Mu unfairly.

The experts and professors below couldn't help but heave a sigh of relief, with happy expressions on their faces, and said:

"Xuanwu is a good name, and it's also the mythical beast of our country!"

"Yes, I have always thought that this naming style is very good. Naming with mythical animals can also show the cultural heritage of our country!"

"Now that we have Xuanwu, let me see it. We must also have Qinglong, Baihu, and Zhuque. I just don't know when we can get them!"

……

The atmosphere in the conference room suddenly became cheerful.

While everyone was happy that their superiors had named the main battle heavy tank they were researching, they couldn't help but think about the future.

Talking and talking.

They turned their eyes to Li Mu.

The slightly younger Wang Zerong asked curiously:

"Advisor Li, you said that our country first had Xuanniao-1, and then Xuanwu-1. Will there be other more powerful ones in the future?"

"Of course there is. I can tell you in secret that my superior wanted to choose two names yesterday, but he gave me one in the end." Li Mu said with a smile.

Hear his words.

Wang Zerong and all the experts and professors in the conference room showed excitement on their faces.

They didn't ask what it was called or what it was.

Just knowing it exists is enough.

……

Afterwards, everyone discussed the matter with great interest for several minutes.

Li Mucai stepped forward to interrupt and said:

"Okay, everyone, be quiet for a moment, and let's get back to work."

"Just now, Director Ma and I listened for a while outside and learned about everyone's current problems."

“As for whether to research an insulating heat jacket or a heat-dissipating heat jacket, my idea is to not use either and instead make a new design.”

Having said that, he paused slightly and prepared to get the small blackboard next to him.

But before he could raise his hand, Zhang Kemao on the side quickly handed him the small blackboard.

"Thank you." Li Mu smiled at him, then continued drawing and said:

"I call it a double-layer aluminum plate air gap design. The principle is very simple, which is to install two layers of aluminum plates on the outside of the barrel and leave an air gap in between to form a heat insulation layer."

"This design can also mitigate gravitational waves to a certain extent and protect the barrel from excessive thermal stress."

"In theory, when the barrel is working, the high-temperature gas and flame will directly act on the double-layer aluminum plate, and the existence of the air gap can effectively isolate the heat..."

He didn't speak fast.

When it was said at the beginning that “the principle is very simple”, Yang Ying and others believed it for a moment.

However, as the explanation went deeper, they soon realized that this was a complete lie.

Everyone's pencils were writing quickly, for fear of missing a word Li Mu said.

……

It took more than half an hour.

Li Mu briefly explained the principles and technical difficulties of the double-layer aluminum plate air gap thermal jacket to help everyone sort out their thoughts.

Specifically, there are actually three aspects of the problem: material selection and processing, air gap control, and balance between heat conduction and insulation.

Once these three problems are solved, success is only a matter of time.

However, he did not just crammed the students with information, but stopped at the point and left "homework" for Yang Ying and the others.

How to ensure the close connection between the aluminum plate and the insulating material and the uniform distribution of the air gap, how to accurately control the size and distribution of the air gap to ensure its 3D stability in a high temperature environment, how to comprehensively consider the balance between the thermal conductivity and thermal insulation effect of the material...

Having said this.

Li Mu picked up the enamel cup beside him and took a sip of tea to quench his thirst.

Seeing that the experts and professors below were all lost in thought, he did not disturb them and quietly left the meeting room.

……

Ma Zhihao, who had been waiting outside the door, saw Li Mu coming out and stepped forward and said, "Advisor Li, are you getting ready to leave? Aren't you going to have lunch here?"

Some time ago.

Li Mu stayed at the Automotive Research Institute all day without taking any rest.

He came out just this morning, obviously he was leaving.

"The research here is being monitored by Professor Yang, so there won't be any big problems. I have other important things to do, so I'll leave first. Please tell them later on my behalf." Li Mu said.

He went to the Aviation College for about a week.

These days, I don’t know what the research situation is like at the Materials Research Institute and the Semiconductor Research Institute. I must go and take a look.

Ma Zhihao heard this and didn't ask any more questions.

After all, he heard it clearly just now. Li Mu now has two research projects on hand.

Another item, he estimated, might even be more important than the Xuanwu-1 main battle heavy tank.

……

After saying goodbye to Ma Zhihao.

Li Mu first rushed to the Materials Research Institute and asked about Zhou Ren’s research progress.

The steel plates, ceramics and fiber-reinforced materials of composite armor are easy to make and not particularly difficult.

Mainly titanium-nickel alloy.

This alloy has excellent heat resistance and strength, can significantly improve the tank's protection capabilities, reduce weight, and has good corrosion resistance.

It can not only be used on the Type 99 main battle heavy tank, but also in other high-end equipment and industrial fields, such as aerospace, electronic computers, energy raw materials, etc.

But being easy to use also means it is difficult to develop.

Xia Guo invented titanium-nickel alloy in 1978, but it was put into practical use even later.

There is still a long way to go to break through this technology and achieve mass production.

Fortunately, what Li Mu has the most right now is time.

After finishing this war with India, Xia will have a relatively stable period of development, and the pressure from the international environment will be greatly reduced.

Of course, it would be best to develop it as soon as possible.

……

After staying in the Materials Research Institute for four or five hours, Li Mu left in the afternoon.

Then I went straight to the Semiconductor Research Institute.

The situation here is as stable as ever.

Each research project team was advancing its progress in an orderly manner. Even the Type 99 electronic system research by Su Dongzhuang and Lei Ming did not encounter too many unexpected events.

After all, I have studied many projects with him, and with the guidance of research plans, I do have this ability.

——Of course, the premise is that Li Mu did not set a trap for them in the research plan.

……

Sent out by Su Dongzhuang and Lei Ming.

Li Mu waved his hand and told them to go back to their work.

Seeing them hearing this, they rushed into the laboratory.

He couldn't help but nodded with relief.

"I just don't know if they can discover what I did." Li Mu thought to himself.

In order to avoid making the research too "smooth", he would always leave some loopholes when making the research plan.

It won’t be a big problem, but it will waste a lot of time.

In short, it's annoying.

"Forget it. Why think about it? I'll feel more at ease if they can solve it themselves." Li Mu shook his head and stopped worrying.

Since we have let Su Dongzhuang and Lei Ming do it, we can't have too many concerns.

Only after this experience can they grow stronger.

……

While thinking, Li Mu came to Huang Xinhua's laboratory.

But this time he didn't listen at the door, but walked straight in.

Huang Xinhua, who was operating the distributed projection light technology, moved his ears slightly, but did not raise his head. Instead, he continued to complete the experiment in his hand.

After about seven or eight minutes, he raised his head and let out a long sigh of relief.

Seeing this, Li Mu stepped forward and said, "Professor Huang, is there any new breakthrough?"

"It's not that easy. Compared to before, it has only increased to 18." Huang Xinhua shook his head and said.

The integration level is 18w. If he had heard this number two years ago, he would have been shocked.

But now, it can only be "that's all".

Li Mu smiled and said:
"It's already very good, Professor Huang, you don't have to worry too much."

“Achieving a breakthrough in integration is not an easy task.”

"We still have a lot of time, so we can take it slow."

His plan is to complete the Type 5 main battle heavy tank within 99 years and the J-10 within 10 years, which is completely possible in time.

"Time waits for no one, Li Mu. You may not know that although our war with India this time has enhanced our national prestige, it will also make Emperor M and Big Brother even more wary!" Huang Xinhua sighed.

He didn't know that after Xia Kingdom finished this self-defense counterattack, it entered a period of stability.

A big win is certainly a good thing.

But it will also make the enemy more fearful, and the next attack will be more fierce.

They won this time, but what about next time, and the next time?
If the country does not become strong soon, the war will never end.

Li Mu was silent for a moment, then slowly said:
"In fact, it's not that there is no way to further improve the integration, but the effect may not be as high as before."

"What? Why didn't you tell me your idea earlier?" Huang Xinhua said happily when he heard it.

God knows how much hair he has lost in recent days in order to improve integration.

Li Mu said: "In fact, I just thought of this recently. We can start from the purity and area of ​​the silicon wafer."

"It's probably not that easy to improve the purity and area of ​​silicon wafers." Huang Xinhua frowned again.

Whether it is purity or area, it involves the issue of processing accuracy.

The higher the purity and the larger the area, the more difficult it is to achieve precision processing.

Given Xia Country's current technological foundation, it would be very difficult to make improvements in this area.

Thinking of this, Huang Xinhua said quickly: "Don't keep me in suspense. Tell me what to do."

He doesn't know how to improve integration.

I still don’t know Li Mu’s personality.

Being able to talk to him, I must have a preliminary and complete plan in mind. Li Mu said:
"This issue actually comes back to industrial machine tools and automated production."

"Now our country has 3+2 axis CNC milling machines, and other 3+2 axis CNC machine tools are also under development."

"I think we can try to add the development of 5-axis machine tools to the plan. As for automation, although it is difficult, it is not that high."

Want to increase purity and area.

We can only start from the process aspect.

Therefore, industrial mother machines and automation are two items that must be upgraded.

"I'm afraid I can't help with the two things you mentioned!" Huang Xinhua said with a long sigh after listening.

He is not proficient in either industrial machine tools or automated manufacturing.

He didn't even know much about software engineering, the flagship of the semiconductor research institute. From the beginning to the end, he was devoted to semiconductors without any distractions.

After all, a versatile person like Li Mu is rare.

For ordinary scientists, it is a good thing to be able to specialize in a field and make some achievements.

"That's true in mechanical manufacturing, but there's also the process aspect. I'm sure you can give me some advice." Li Mu said with a smile.

Hearing this, the look of disappointment on Huang Xinhua’s face finally disappeared.

The two of them immediately began to discuss how to improve the level of the process.

The production of large-size silicon wafers requires higher process technology requirements and involves multiple steps, such as cutting, polishing, thin film deposition, etc.

As the size of silicon wafers increases, the difficulty of controlling these process links also increases accordingly.

For example, when cutting large-sized silicon blocks, higher precision and stability are required to ensure the quality of the silicon wafers; during the polishing process, a larger surface area needs to be processed to ensure surface flatness...

……

Until about 10pm.

Li Mu and Huang Xinhua stopped talking and prepared to leave.

Of course, that doesn’t mean they have finished talking - the issues of semiconductor technology may not be exhausted even if they talk for two days and two nights.

But Wang Ya came to the laboratory from 9 o'clock.

Being stared at is nothing.

The key is that she would add some tea to the two of them from time to time.

In an hour, Li Mu and Huang Xinhua drank 4 bottles of water from the thermos.

Li Mu could bear it, but Huang Xinhua really couldn't bear it anymore and could only get up and leave quickly.

……

After returning home.

Li Mu followed Wang Ya's request and had a good night's rest.

The next day, he was in no hurry to go out to work.

Instead, he set aside a morning to study the theory of energy mobility.

Take out a stack of manuscript paper and spread it out on the table.

He picked up the pen and began to think.

Compared with previous fighters, third-generation fighters no longer emphasize high-altitude and high-speed combat, but instead emphasize the ability to engage in air combat at medium and low altitudes.

It has the ability to reach the battlefield quickly and has strong maneuverability at medium and low altitudes.

This design concept requires that third-generation fighter jets be able to quickly recover energy, maintain high speed and altitude when performing maneuvers, so as to gain an advantage in the air.

This also involves the theory of energy mobility.

This theory was only proposed in the 70s. Its core is to evaluate the maneuverability of fighter jets and use a simple mathematical formula to calculate the unit residual power of fighter jets.

That is (thrust - drag) * speed / weight.

In practical applications, it is mainly reflected in gaining tactical advantages by optimizing the kinetic and potential energy states of the aircraft.

The specific application can be manifested in two aspects:
First, it is the conversion of kinetic energy and potential energy.

At high speed, kinetic energy is converted into potential energy through upward maneuvers to slow down the speed; when the speed is insufficient, potential energy is converted into kinetic energy through downward maneuvers to accelerate the pursuit of enemy aircraft.

This energy conversion strategy allows pilots to flexibly adjust in different air combat situations, play to their strengths and avoid their weaknesses, thus creating an advantage over the enemy.

The second is the management of height and speed.

Energy maneuverability theory requires pilots to always pay attention to the altitude and speed of the aircraft and adjust the flight status according to combat needs.

For example, when flying at high speed, the aircraft can be reduced in speed by climbing to better control the aircraft. When acceleration is required, the aircraft can be released by descending to quickly pursue the target.

……

Li Mu spent a whole morning writing down a slightly simplified theory of energy mobility on paper.

After all, a newly created theory cannot be made particularly perfect and will always have some flaws.

Then he asked Guan Jianmin to send the document to the Aviation Academy and let Huang Qianqian and others study it first.

The theory of energy mobility is relatively important.

Its appearance rewrote the history of air combat.

Because it is not only an air combat tactical theory, but also a fighter design concept.

Although Huang and others have initially understood the design concept of the J-10, their design ideas are still stuck in the era of second-generation fighter jets.

Providing them with more information can help them update their knowledge faster.

"There's also radar, I have to find a way to deal with it." Li Mu walked to the window, thinking while looking at the distant scenery to relieve his slightly sore eyes.

The difficulty of developing the J-10 is much greater than that of the Type 99 main battle heavy tank.

Not only do we need to solve the problem of fly-by-wire flight control, but we also need to solve the problem of onboard avionics equipment.

The most important thing is radar.

The early J-10 was equipped with a flat-plate slot antenna radar and a dual rectangular adjustable air inlet, and used a Type 1473 pulse Doppler radar.

The maximum detection range of this radar is 130 kilometers. It can track 10 targets at the same time and attack the four most threatening targets at the same time.

The task is not too difficult to complete, after all, the Radar Research Institute already has a certain foundation in pulse Doppler radar research.

"But since we plan to spend 10 years on the research, let's not think about the active phased array radar for now. Let's at least make a passive phased array radar." Li Mu thought secretly.

Active phased array radar has the ability to enable third-generation fighters to leap into the ranks of third-generation and a half fighters.

But it is very difficult to do it now.

It would be better to take it step by step and first develop the domestically-produced passive phased array radar KLJ-10 installed on the J-3B.

"There are also detectors used in infrared search and tracking systems. Let's not consider the long-wave ones for now. Let's work out the short-wave ones first." Li Mu began to write.

He is still quite pragmatic.

The J-10 has undergone many upgrades, and the later versions are definitely more powerful than the previous ones.

But no matter how powerful it is, it is not easy to make.

Given Xiaguo’s current situation, it would be more appropriate to solve existing problems first and then solve good problems.

……

In the study room.

Li Mu quickly wrote lines of words on the manuscript paper with a pen, and the sound of "swish~" was heard continuously.

Of course, he didn't just copy.

From time to time, I would stop and think for a moment, trying to fully understand every theory and idea.

After all, only if there is no problem with it, the design and manufacturing of the J-10 will be fine.

Just when he was writing with great concentration.

Suddenly, I smelled a faint aroma of food.

All of a sudden, my stomach started to growl.

He raised his wrist to look at the watch. Before he knew it, he had been writing for another three hours.

"No wonder I'm so hungry." He stood up helplessly and opened the study door.

As expected, in the living room, Guan Jianmin was opening lunch boxes one by one on the dining table.

When I saw him come out, his eyes were full of resentment.

"Okay, okay, it's just that we're three hours late for lunch. It's no big deal." Li Mu said as he quickly sat down at the dining table and started to eat.

Seeing this, Guan Jianmin said unhappily:

"Isn't it? In two or three hours, we can have dinner."

"It's because you came out this time, otherwise I wouldn't have reported it to the higher-ups."

"You should also tell Comrade Wang Ya about what you did today!"

He couldn't do anything to Li Mu.

But it doesn’t matter, you can file a complaint.

Li Mu, who was eating, widened his eyes and said quickly, "Okay, okay, you are awesome. I admit defeat. This is just this once, and it won't happen again."

He drank a bellyful of tea yesterday.

But I dare not let Wang Ya know about this.

"By the way, did Professor Huang and the others say anything after they got the documents I gave them?" Li Mu changed the subject.

Talking about business, Guan Jianmin put away his joking expression and said:
"Professor Huang and the others didn't seem to understand for a moment, and said they hope to consult you after you pass by."

"Is that so? Then it looks like there's no problem. The person shouldn't be able to escape." Li Mu said with a smile.

The reason why he contacted Huang and others, was willing to spend time and energy, and even brought them to the Aviation Academy later, was all to keep them.

After all, although the higher-ups attach great importance to it, it is still a bit difficult to attract so many experts and professors at once.

And we also have to consider the wishes of Huang Qianqian and others.

Even though they are very enthusiastic about learning from me now, if they really open their mouths, it’s hard to say how many of them will stay.

Seeing this, Guan Jianmin was speechless and said, "Run? I think they all want to stay here, how can they run away?"

Father, like son.

Maybe Li Mu didn't notice.

But he often saw the expressions of professors such as Huang Qianqian and Tu Jida when they surrounded Li Mu and asked him questions.

From appreciation, to admiration, to amazement.

Not to mention running away, I'm afraid everyone would want to stay.

"You can't say that. If they don't speak, I can't speak either. Otherwise, there will be no room for maneuver." Li Mu shook his head.

……

at the same time.

This is the Aviation Institute.

Huang Qianqian, Tu Jida, Song Wencong and others who had received the documents sent by Li Mu were gathered together to discuss.

But they were not discussing the theory of energy mobility.

Instead, they were discussing how to find a way to tell Li Mu that he wanted to stay and do research together.

Last time, Song Wencong was arranged to be their representative, and things went very smoothly.

But who would have thought that a Cheng Yaojin would appear halfway? Tang Yanjie's appearance and the news that Xia had defeated India interrupted their plans.

Afterwards, Li Mu was taken away directly and was gone for more than a day.

Although a document has been sent over now, who knows when the person will be able to come back.
