The Red Era, the Opening University Speech

Chapter 447 Tianhedian

Two days later.

Li Mu looked through all the information in the archives of the Bohai Shipyard and sorted them out in detail.

Done this.

Although his level is still not as good as that of experts like Huang Weilu and Zhao Renkai who have been immersed in the field of atomic submarines for many years.

But at least when it comes to professional knowledge, there are no common sense issues.

……

In the factory director's office.

Li Muyi came in.

Then he saw Huang Weilu and others who had been waiting there.

Everyone stood up and said excitedly:

"Advisor Li!"

For them, these two days can be said to be like a year.

If it weren't for the research task of anechoic tiles and anechoic coatings.

I don’t know how to get by.

"Why are you being so polite? Sit down." Li Mu smiled and asked:

"Is the research on anechoic tiles and anechoic coatings going well?"

Huang Wei Road:

"It went smoothly. According to the direction you gave, we have begun to try synthetic materials."

"And with the help of material calculation software, the speed is more than ten times faster than before."

"I believe that it won't be long before a relatively complete result comes out."

After he finished speaking, a smile appeared on his face.

After all, the research went smoothly, which is quite gratifying.

"That's right, then we can also concentrate our energy and focus on solving the problem of submarine-launched D missile." Li Mu nodded with satisfaction and said.

Hearing this, Huang Weilu and the others were all shocked, their eyes filled with excitement.

Li Mu continued:
"Let's talk about its core technology first."

"First of all, we need to develop solid rocket engines to replace the existing liquid rocket engines."

"Its quality will directly affect the performance, reliability and applicability of the submarine-launched D missile, and it is a key technology that we must break through."

There is no need to explain the advantages and disadvantages of solid rocket engines and liquid rocket engines.

The former is suitable for scenarios that require rapid preparation and maneuverable launch, while the latter is more suitable for space missions that require precise control and long-term thrust.

"Advisor Li, are you planning to use modified double-base propellant as the propellant for solid engines?" Huang Weilu asked.

He didn't know who invented this thing.

However, there is no doubt that modified double-base propellant is easy to use.

"The modified double-base propellant should be barely enough. If not, we can continue to improve it." Li Mu nodded slightly.

Later generations of submarine-launched D bombs mostly used modified composite double-base propellants and high-energy solid propellants.

Of course, this does not mean that modified double-base propellants are not feasible.

For quite a long time, this has been the main raw material for solid rocket engines, which is enough to prove its value.

Huang Weilu thought for a moment and said:

"Then I suggest that we find someone to study first."

"Anyway, Leader Qin Yun gave us the authority, so why not use it?"

"If we can make another breakthrough, it will be a good thing for our development of submarine-launched D missiles."

After he finished speaking.

Zhao Renkai, Li Yichuan and Hu Xuhua standing by also nodded in agreement.

When it comes to scientific research, it’s always a good idea to prepare in advance.

"Well... don't worry, the people are already here." Li Mu smiled and said.

This answer made Huang Weilu and others confused for a moment.

coming?

How come they didn’t know about this? The factory director is really something. He didn’t even tell us such an important thing!
"Advisor Li, which professor are you talking about? I'd like to trouble you to introduce him to us. We will visit him later." Huang Weilu said.

Although it was a bit strange, they did not doubt the truth of it.

Perhaps the other party's identity was too mysterious, so he didn't reveal any information at all, which can still be explained.

"It's not some professor...it's just me." Li Mu said helplessly.

Hearing this, Huang Weilu stood up suddenly and said:

"Is it you?"

No wonder he was so surprised.

You must know that the emergence of modified double-base propellant has a significant impact on the entire aerospace industry of Xia Country.

He originally thought that it would be the result of some respected old expert.

I didn’t expect it was Li Mu.

This is a bit too shocking.

"Advisor Li is worthy of being valued by Leader Qin Yun!" Zhao Renkai and others were also deeply moved.

If Li Mu hadn’t said it himself.

I'm afraid they would never have thought that this was something he made.

"It's just some of our previous achievements, not worth mentioning. Let's continue talking about rocket engines." Li Mu said with a smile.

Huang Weilu then slowly sat down.

But it is not difficult to see from his curious eyes that his heart is full of curiosity at this moment.

Not only him, but also Zhao Renkai, Li Yichuan and Hu Xuhua.

They really wanted to know how much Li Mu had researched.

……

Curiosity is curiosity.

As Li Mu continued to talk about his research.

The four of them quickly focused and began to listen.

Li Mu said:
"Let's talk about the engine structure first. My idea is to break through the original single-stage structure and adopt a two-stage structure, or even a three-stage structure."

"The M Empire's Minuteman intercontinental missile uses a three-stage structure, and its range reaches 13000 kilometers."

"Of course, this is a land-based intercontinental D missile. It's definitely different underwater. But if we try hard, we should be able to reach a range of about 5000 kilometers."

He first set a goal for everyone.

A three-stage solid rocket engine is definitely difficult.

After all, the U.S. Empire's current Polaris submarine-launched D missile only uses a two-stage solid-fuel rocket engine, and its maximum range is only 2200 kilometers.

5000 kilometers, almost twice as much as the other side.

However, Huang Weilu and others were not aware of this. After all, the range of this advanced weapon was a military secret in the M Empire.

But it's totally enough.

After all, the straight-line distance between Xia Kingdom and Emperor M is only about 14000 kilometers.

With a range of 5000 kilometers, it can completely cover half of the ocean battlefield.

Thinking of this, Huang Weilu suddenly shuddered and asked:

"Advisor Li, it's 5000 kilometers underwater, how about on land?"

His question made Zhao Renkai and others swallow their saliva.

After all, it can hit so far underwater.

Then on land, can't we directly attack the homeland of Emperor M?

To know.

An attack at this distance, coupled with the big mushroom, is the most deterrent weapon.

"Well, it's hard to say. And it can't be converted equivalently, after all, the launching platforms are different." Li Mu shook his head and said.

The technology for land-based intercontinental D bomb is a bit difficult.

And even if it is made, it is still unknown whether it can be accurate.

"I understand. Consultant Li, you are really rigorous!" Huang Weilu sighed, then sat back in his seat without asking any more questions.

After all, land-based intercontinental D missiles use fixed launch silos and mobile launch vehicles.

The submarine-launched D missile is used by submarines.

Different launch platforms will lead to differences in many key technologies. It is not convincing to judge the range only from the rocket engine.

Li Mu smiled and said:
"Let's continue talking about rocket engines."

"Let me first talk about the difference between level one and level two."

"It does not eliminate the first-stage engine, but adds an engine on its basis..."

He slowly explained the difference between the first and second stages of a solid rocket engine.

The structure of a single-stage solid rocket engine is relatively simple, mainly consisting of a propellant, a combustion chamber, a nozzle assembly and an ignition device.

The grain is a hollow cylinder made of propellant and a small amount of additives, placed in the combustion chamber.

A two-stage solid rocket engine is composed of two independently working single-stage rockets connected in series.

The first stage works first and separates after the fuel is exhausted, and then the second stage rocket ignites to continue accelerating flight.

Speaking of it.

Hu Xuhua raised his hand and asked:
"So, Advisor Li, compared to the second stage and the third stage, is it possible that a single-stage rocket engine is also added?"

After asking this question.

Huang Weilu and the other two couldn't help but look at him, with a hint of pity and relief in their eyes.

In fact, they don’t understand either, but because of face, they can’t ask directly.

Li Mu explained:
"No, by the third stage, the solid rocket motor will need higher thrust and longer burning time."

“And it also needs to be equipped with a more complex thrust adjustment system to ensure it hits the target accurately.”

"With the effect of modified double-base propellant and our current thrust adjustment methods, it is difficult to meet its requirements."

After he finished speaking.

Hu Xuhua smiled embarrassedly, feeling that he had asked a stupid question.

Huang Weilu, who was standing by, was aroused by curiosity and said:

"Thrust adjustment system, how are we going to implement this? Do you have any direction you can give us?"

"This involves computer control systems, but with our current technology, it will take at least five or six years to make a breakthrough in this area," said Li Mu.

Computers have indeed played a vital role in the experiments and applications of three-stage solid rocket engines.

For example, the application of microcomputer programmable controller in solid rocket engine experiments.

It can replace traditional relay contactors, sequence controllers and stepper controllers to achieve more efficient automatic control.

"By the way, we can also develop a solid rocket engine integrated design system software and add modules such as system execution control, system input, and system output to assist in the design." Li Mu suddenly thought.

Ordinary CAD is also of great help in design work.

But after all, it is not as convenient as specialized software, and its functions are more complete.

It was impossible for him to come up with a complete design plan directly, and he couldn't stay in the Baltic Shipyard forever. There would always be a day when he would leave.

By then, there will certainly be problems of varying sizes in design.

If there was a design software, it would undoubtedly greatly reduce the pressure on Huang Weilu and others and greatly speed up the research.

Next, Li Mu spent another three days to simply build the research framework of the submarine-launched D missile.

The missile body, warhead, power unit, guidance device, power supply system and launch device, a total of 6 parts, divided into 6 groups.

Huang Weilu and Zhao Renkai are the project’s team leader and deputy team leader, responsible for daily management and research.

Besides.

Hu Xuhua, who will achieve extraordinary success in the future, and Li Yichuan, who has good abilities but died young.

Under his recommendation, they were appointed as the team leaders of the missile body and power unit. Of course, this was just a basic team.

In the future, more experts and professors will be needed to meet the research needs of the entire submarine-launched D missile.

However, after handing over some of the personnel application reports to Ding Xiuxun.

These things have nothing to do with me for the time being.

After all, he had been at the Baltic Shipyard for a week!

……

Dormitory door.

Li Mu was saying goodbye to Huang Weilu and others.

Behind him was Bincheng County Magistrate Jiang Zhe who came after hearing the news.

The latter heard that he was leaving.

He immediately ran to the factory and warmly invited him to visit Bincheng.

To be honest, Li Mu was indeed a little moved.

After all, Bincheng is by the sea and has a lot of delicious seafood.

It’s a pity that he is really anxious to go back now and can’t stay here for long.

So I could only politely decline the other party's kindness and said:
"Leader Jiang, I broke my promise. Next time I come, I will apologize to you in person."

"You're too kind, Consultant Li. It's not a big deal. Your matter is more important." Jiang Zhe said hurriedly.

Of course he knew that it was impossible to keep the person this time.

After all, the commotion Li Mu caused at the Bohai Shipyard this time was extremely big.

If even such an important research task could be put aside.

So it’s probably no exaggeration to say that what Kyoto is doing is world-shattering.

"It's settled then. Next time I come, I will definitely stay at your place for two days." Li Mu said with a smile.

After saying that, he turned his gaze towards Huang Weilu and the other three.

I saw that all of them were dejected, with reluctance in their eyes.

Even though we only spent a week together.

But they have already established a deep friendship with Li Mu.

I also learned so much from following him.

Not just submarine-launched D bombs.

We also gained a lot of inspiration from the research on atomic submarines.

So that each of them has a feeling.

——If Li Mu had been there all the time, they would have been able to develop the submarine-launched D missile along with the atomic submarine within two years.

"Advisor Li, can't you stay a few more days? Without you, our research speed will definitely be greatly affected!" Huang Weilu said.

After enduring for a long time, he finally couldn't hold it in.

After all, the entire submarine-launched D bomb, as well as the research project on anechoic tiles and anechoic coatings, were all based on the theoretical foundation established by Li Mu himself.

Without him, no one can guarantee that nothing will go wrong.

Huang Weilu spoke.

Li Mu was not surprised and said with a smile:
"I really can't stay here any longer. There are still very important matters to deal with in Kyoto."

"I believe that even without me, Professor Huang, you can still do a good job in research."

"And this time I went back to try and see if I could come up with a computer software specifically designed for solid rocket engines to assist in my research."

He came here during these three days, in addition to his research.

He also looked up a lot of information.

This includes the solid rocket engine integrated design system software - SRMCAD.

This software adopts a modular design and includes multiple functional modules.

Each module has unique capabilities and together support the overall design of the rocket engine.

If it can be developed, the research time of solid rocket engines can be shortened by at least 300%.

"No matter how good the software is, it's not as good as Consultant Li!" Brigade Commander Huang Wei sighed.

Computer software is indeed powerful and can greatly speed up research.

However, this also has prerequisites.

First of all, at least you can't make a mistake in the direction.

Once you make a mistake, you will be going in the wrong direction. The farther you run, the more time and energy you waste.

But if Li Mu were here, all this could have been avoided.

"Okay, Professor Huang, it's not like Consultant Li won't come. Kyoto and Bincheng are not far away, so there will be many opportunities for us to meet in the future." Ding Xiuxun advised.

Hear this.

Huang Weilu felt much better.

……

Then, under the gaze of everyone.

Li Mu left under the escort of a security truck just as he came.

Accompanying him were Ding Xiuxun and Jiang Zhe.

Although he repeatedly declined and told them not to bother.

But it was obviously impossible to stop the two people who wanted to get closer to him, so he had no choice but to agree.

……

And at the gate of the Baltic Shipyard.

Watching Li Mu disappear in the car at the end of the road.

Huang Weilu also kept looking into the distance, and it took a long time before he reluctantly looked away.

It was not until the wind and sand blinded his eyes that he turned his head regretfully.

As he was rubbing his eyes and walking back.

Suddenly I realized that Zhao Renkai and the other two hadn't left either.

But it was different from his expression.

On the contrary, the three of them did not look very sad. They even looked a little happy while chatting.

They were clearly the same as him just now.

Why did his expression suddenly change now?

Thinking of this, Huang Weilu stepped forward and said:
"What are you talking about? You look so happy. Don't you care at all that Consultant Li is gone?"

"Of course." Zhao Renkai nodded and said, "Just leave if you want to. It's not like we won't see each other again."

Hearing this, Huang Weilu was stunned.

That's right.

But it’s hard to say when we will meet again.

"Haha, you don't understand, right? Then I'll tell you directly, Consultant Li won't be able to come over in the short term, but that won't affect our going over." Zhao Renkai continued.

This sentence suddenly made Huang Weilu cheerful.

……

Bincheng Railway Station.

Accompanied by the sound of a train whistle.

The special train slowly drove out of the platform.

The guards in charge of security saluted in unison and watched the train leave.

Li Mu stood at the window and waved to Jiang Zhe and Ding Xiuxun who came to see him off, then returned to his room in the carriage.

Sitting on the sofa.

He closed his eyes slightly and rested, carefully reviewing the trip to Bincheng.

I have to say that the harvest was quite good.

Not only did he come into contact with a large amount of information on nuclear submarines, but he also took the opportunity to propose anechoic tiles, anechoic coatings, anti-submarine radar and submarine-launched D-bomb technology.

Although except for the anechoic tiles and anechoic paint, the remaining two cannot be completed in a short time.

But even if only the first two are successful, the improvement in the current strength of Xia Country’s navy will be quite obvious.

At least in near-shore defense, we can take more initiative.

"Land, sea and air, the only things left are sky and electricity." Li Mu opened his eyes and sat down in front of the window seat.

The wars of the future will be information-based wars, and will also be integrated wars involving land, sea, air, space and electronics.

Having advantages only in the three areas of sea, land and air is still somewhat insufficient.

We also need to make efforts in both the sky and electricity.

The sky is the space above the atmosphere, which can also be called outer space.

It plays a vital role in modern warfare.

It is not only a supporting platform for key technologies such as satellite communications, navigation and remote sensing.

It also has important applications in military reconnaissance, D-missile guidance, etc.

"But given the current situation, it might be more important to work on electricity." Li Mu thought.

Considering Xiaguo’s current technological level, if the aerospace industry wants to enter a period of rapid development, it will require huge amounts of capital and technology as support.

When the capital accumulation is not complete.

Even with the help of powerful supercomputers, the role they can play is very limited.

Take the first satellite for example, it took 70 years to be successfully launched.

There are still more than 7 years from now.

Even if the time is reduced by half, it will still take nearly 3 years.

However, no matter how powerful a supercomputer is, it is impossible to really increase efficiency by 50%. Achieving 20% ​​to 30% would already be a very ideal situation.

"There was already electromagnetic warfare in the 60s, a fight for the right to use and control the electromagnetic spectrum. But there is still a gap with later generations," Li Mu pondered.

Later electromagnetic warfare covered a wider range of electromagnetic spectrum technologies, including infrared, laser, microwave and satellite communications.

It has also expanded to multiple fields such as cyber warfare, information warfare, and space warfare.

However, electromagnetic warfare in the 60s mainly relied on radio communications and radar technology.

There was a joke in later generations.

Good news: radar detected no enemy ships.

The bad news: It's visible from the deck.

This is exactly one part of electromagnetic warfare.

If we can take the initiative in electromagnetic warfare, it will have a significant impact on the improvement of Xia's overall military strength.

"The other thing is electromagnetic pulse. This is a good thing. I can find someone to study it when I have time." Li Mu continued his plan.

Electromagnetic pulse is also a part of electromagnetic warfare.

It uses high-energy electromagnetic waves to destroy electronic equipment and components, rendering them ineffective or damaged, thereby achieving war objectives.

This weapon can instantly paralyze the enemy's electronic equipment such as power systems, communication systems, radars and anti-missile systems, thereby achieving a non-contact, zero-casualty attack on the enemy.

The U.S. used electromagnetic pulse weapons for the first time in the Gulf War, which had a significant impact on Iran's communications and radar systems.

This was followed by the "Harp" experiment in 93.

During this test, the U.S. Army launched an electromagnetic pulse, which blocked the communication system and successfully destroyed the incoming D missile.

Later in the development, high-energy electromagnetic pulse weapons and Big Goose's small strong electron accelerator appeared.

"And it can be used in conjunction with nuclear bombs. It is definitely a powerful weapon that can deter Emperor M and Big Brother." Li Mu thought secretly.

The destructive power of atomic energy EMP is mainly reflected in the damage to electronic equipment.

By releasing high-energy electromagnetic pulses, it can destroy all electronic equipment within range in a short period of time, causing paralysis of communications, transportation, energy and other infrastructure.

Moreover, this explosion takes place high in the atmosphere outside the atmosphere and will not produce the shock waves and thermal radiation of traditional nuclear bombs.

"If this bullet hits Emperor M or Big Brother, it will be enough to scare them so much that they won't be able to sleep well for more than ten years." Li Mu thought secretly.
