The Red Era, the Opening University Speech

Chapter 444: The Navy Generals' Covetousness for Li Mu

In terms of the current level of technology.

The noise generated by an atomic-powered submarine while traveling at medium to high speeds is much smaller than that of a conventional-powered submarine.

As for low speed state.

If it weren't for the fact that atomic reactors cannot be easily shut down, and conventional submarines can simply shut down all their power units, there would be no advantage.

"I can't say for sure what effect it can achieve, but at least it will be difficult to detect when driving at medium and low speeds." Li Mu thought for a while and said.

He didn't say too much.

After all, he knew almost nothing about Xia Country's current submarine technology.

It is difficult to have a comprehensive understanding and grasp of the current submarine industry based solely on the few records found in later databases.

The reason why he dared to say that he could make submarines completely "invisible".

I just don't believe in the current sonar technology of Emperor M and Big Brother.

……

After getting Li Mu's answer.

The professor who asked the question quickly sat down.

Although this answer was not what he wanted.

But he couldn't continue asking.

After all, before scientific research is successful, no one can guarantee what the final result will be.

Other researchers also understand this.

But as long as it is possible, that's enough.

A group of them immediately expressed their willingness to follow Li Mu to study sound-absorbing tiles and sound-absorbing coatings.

……

A welcome party.

In the end, it became a project launch meeting for sound-absorbing tiles and sound-absorbing coatings.

After confirming the basic feasibility of the research.

Soon a six-member team centered around Li Mu was formed to take charge of related research matters.

Huang Weilu is the deputy team leader, and the team members include Hu Xuhua, Li Yichuan, and a group of key researchers from the shipyard.

As for the team leader, it must be Li Mu.

……

Looking at the group on stage.

The experts, professors and researchers in the auditorium had regret in their eyes.

I just regret that I am not capable enough and was not selected.

But they didn't know that Li Mu was also confused at this time.

The matter was settled in a few words.

He originally wanted to be a consultant.

Unexpectedly, as soon as the discussion was over, they came up and said that he would be the team leader.

In this regard, Li Mu was helpless and said:
"Director Ding, Professor Huang, I'm just here to take the test. I can't stay for too long!"

Sound-absorbing tiles and sound-absorbing coatings are very important.

But no matter what, the research on the Weilong-1 fighter and the Xuanwu-1 main battle heavy tank cannot be more important.

After all, the former can only allow Xia Kingdom to have the means to deter Emperor M and Big Brother's fleet.

As for the latter, it might be a little difficult to ride on their heads and take a dump, but it is definitely no problem to take a few laps over there to promote the country's prestige.

"It's okay, Consultant Li. If you are short on time, we can follow you to Kyoto!" Huang Weilu said without any hesitation.

Seeing this, several other team members also expressed their willingness to follow.

They didn't ask why.

After all, as a core scientist of Xia Country, it is normal for him to have one or two top-secret research projects.

"Forget it. We need you more here. Let me see if we can establish the research framework as soon as possible." Li Mu shook his head and said.

It's a bit exaggerated to bring people there just for a sound-absorbing tile and a sound-absorbing paint.

Although breakthroughs in materials require the most time and effort to experiment.

But he doesn't have to worry about that at all.

After all, there is quite detailed information in the materials laboratory of Jianqiao University.

He just needs to copy and he can get something done.

The only thing to worry about...

Li Mu looked at Huang Weilu and the others, who looked like they were willing to sacrifice everything for the sake of research, even if it meant working day and night to complete it.

I couldn't help feeling a little guilty.

Instead, he had to control his speed so as not to be too shocking.

Immediately afterwards, Li Mu quickly led Huang Weilu and others to carry out theoretical research.

The structure of the sound-absorbing tile mainly includes rubber or synthetic polymer materials, with thousands of tiny cavities inside.

Specifically, sound-absorbing tiles are usually made of rubber, ceramic or polymer.

It is less than 7 cm thick and can effectively respond to sonar signals in the high-frequency range.

Its internal structure contains thousands of tiny cavities, which produce bubble deformation when sound is incident on them.

This absorbs sound energy, reduces reflections and reduces noise inside the boat.

This also involves the material's "viscous internal friction" and "elastic relaxation process".

The former refers to the internal friction generated by the interaction between molecules during the flow of the fluid.

This internal friction is the ability of the fluid to resist shear deformation and is manifested as the viscosity of the fluid.

The magnitude of viscosity is usually measured by viscosity. The greater the viscosity, the greater the fluid's ability to resist shear deformation.

The latter refers to the process of the system gradually recovering from a non-equilibrium state to an equilibrium state.

……

Keep busy till late at night.

Li Mucai walked out of the auditorium.

The evening breeze in the factory is unusually refreshing, and if you smell it carefully you can even detect the unique salty smell of the sea.

He took a deep breath, calmed himself down, and then returned to the dormitory with Huang Weilu, Zhao Renkai and others.

We discussed it for an afternoon.

The latter and others were also a little tired, so they talked about the 033A test.

This test will be held tomorrow afternoon.

By then, many naval leaders will be present.

However, Li Mu didn't quite understand this.

He might know who the top ten generals are, but he really doesn't know much about the navy.

……

Go back to dorms.

Li Mu did not rest immediately.

Instead, he sat down at his desk and continued working.

Just a sound-absorbing tile and a sound-absorbing paint are far from enough.

His ultimate goal is still the ballistic D bullet.

Only this can enable Xia State to truly have the right to speak in the ocean field.

Ballistic D-bomb, also called submarine-launched D-bomb.

If you want to make it, you first need to overcome X difficulties.

The first step is underwater launch technology.

If you want to launch a missile underwater, it is almost impossible to do so without a powerful underwater D-missile launching system.

The current submarine-launched D-missile launch technology is mainly "cold launch".

D But now the launch device uses high-pressure gas to protrude from the trajectory. After reaching a certain height, it is ignited with the help of rocket thrusters.

In addition, the D bomb's own power is used to achieve "hot launch" for ignition.

Both have their pros and cons.

However, Li Mu still prefers to study the former.

"Cold launch is safer and has a wider range of applications. The only problem is that the structure is a bit complicated, but complexity also means reliability." Li Mu slowly recorded on paper.

Thermal emission has a simple structure, small mass and high emission rate.

However, the safety risks are too great, and the exhaust and high temperature generated during launch can easily be detected by the enemy.

Since there is a better option, it should naturally be sent out.

"Then comes the second stage, advancing technology." Li Mu continued to check the information.

The quality of propulsion technology directly affects the range of the D missile.

The modified double-base propellant he researched can be used here, but it is not enough.

The propulsion system of the submarine-launched D missile is mainly composed of engines and fuel.

The engine is the core. The more powerful the engine, the greater the power of its propulsion system, and the farther the D bullet can be fired.

Currently, both the M Emperor and Big Brother use solid fuel rocket engines.

"I want to make it, it shouldn't be a problem, but I can also try to research other technologies." Li Mu said secretly.

His eyes swept across the names of engines such as scramjet engine and multi-pulse engine on the chat page.

Of course, there are other ways to improve engine performance.

For example, reducing mass.

The most common method is to use organic fiber composite materials, new reinforced fibers, resin composite materials, etc. as engine casing materials.

However, he estimated that with the current level of material development in Xia Country, the possibility of producing it was not high.

After all, if you want to produce the material, a detailed plan alone is not enough, there are also very high requirements on the craftsmanship.

"The next step is guidance, but this is my strong point." Li Mu then looked at the third level.

Like land-based missiles, submarine-launched missiles are generally guided by a combination of inertial guidance and satellite navigation guidance.

Although they don't have a satellite, with him around, they will definitely be able to launch a satellite into space within five years, so now is the right time to start researching it.

But in terms of computers, it is in an absolute leading position.

The missile's own position information before launch is provided in real time by the launching platform submarine.

The missile combines this initial information with its own guidance information, and uses the computer inside the D missile to analyze and calculate, and then correct the trajectory in real time.

With Xiaguo's current computer level, it is not particularly difficult to achieve this.

Next, it’s the last level.

"Big Mushroom Warhead." Li Mu's eyes fixed on these words.

He doesn't need to worry too much about this.

……

The next day, early.

Li Mu continued to discuss the development of sound-absorbing tiles and sound-absorbing coatings with Huang Weilu and others.

until noon.

The group was engrossed in the discussion when they were interrupted by Ding Xiuxun, who told them to go to the cafeteria to eat immediately.

This naturally caused a lot of complaints from the crowd.

After all, we had monitored their daily routines before, but never so strictly.

See they are dilly-dallying.

Ding Xiuxun had no choice but to remind:

"Don't forget, in a little while, the leaders above will all be coming down."

“Research is important, but today’s testing is just as important.”

"Our mission today is to complete the test successfully first, and then the research work."

He understood everyone's feelings.

But if we let Li Mu be dragged along, we can chat here until the test begins.

Then go to the test on an empty stomach.

He estimated that nine out of ten people would be criticized.

"Professor Huang, let's go eat first. We'll continue our research after today's test is finished," Li Mu said.

Hear his words.

Although everyone was still a little reluctant to leave, they had no choice but to head to the cafeteria to eat.

……

The time soon came to afternoon.

Inside the dock.

The Type 033A submarine is ready.

Li Mu had just arrived at the stands with Huang Weilu and others.

Then I saw a group of generals in white military uniforms walking towards this side.

As soon as I saw him.

The three men in their fifties who were walking in the front showed joy in their eyes, stepped forward quickly and said:
"You must be Consultant Li, I have heard of you for a long time."

"I am Lin Fei, an admiral of the East China Sea Navy." "Haha, hearing about you is worse than meeting you in person. You are surprisingly young!"

As the first person spoke.

The other two followed suit and introduced themselves.

One is the South China Sea Navy general, Xiao Ruilin, and the other is the North China Sea Navy general, Wu Jinguang.

"Hello three leaders, you are too polite. You should let me introduce myself first." Li Mu quickly shook hands and greeted them.

These three people are all senior naval officers.

In terms of status, he is only second to the top ten generals, which is frighteningly high.

Lin Fei said:
"Hey, what's this?"

"You are an important scholar in our country, and we should respect you."

"Come, let's sit here. You don't have to be so polite."

As he spoke, he and another naval general enthusiastically pulled Li Mu to sit down in the stands.

……

After the big boss from the navy arrived.

After a brief speech.

Testing of the Type 033A submarine will begin soon.

The Baltic Sea Shipyard adopts the floating dock launching method.

A movable and sinking "concave"-shaped cabin is used, and the height is adjusted by filling and draining water from the hull.

This method is suitable for small conventional submarines.

The operation is not complicated and also saves effort.

After the Type 033A submarine was successfully launched.

Li Mu couldn't help but stand up from his seat, staring at the water.

This conventional-powered submarine equipped with magnetohydrodynamic propulsion is extremely important to the Xia Kingdom.

If successful.

Their submarine technology will undoubtedly achieve a qualitative leap.

Seeing Li Mu standing up, Lin Fei, Wu Jinguang and Xiao Ruilin, who lived next to him, also stood up and looked at the water.

Seeing this, others followed suit.

In a moment, all the people who were originally sitting in the stands stood up.

Everyone's eyes were fixed on the water, waiting for the results of the test.

……

after an hour.

The Type 033A submarine surfaced.

Huang Weilu, who was in charge of the testing work, strode towards the crowd after obtaining the data from the testers.

He opened his mouth and said:

"Success!"

These three simple words caused the crowd in the stands to cheer loudly.

However, Li Mu was not in a hurry to be happy, but asked:

"What were the results of the sonar test?"

Hear his words.

The voices of the crowd that were originally cheering also became quieter.

Everyone knows that this is the most important data.

033 is a submarine currently in service.

Although the design cannot be said to be perfect, at least there are no major problems.

Therefore, the successful launch was a matter of course.

"We used the most advanced sonar in the country, but we could hardly detect any sound waves," Huang Weilu continued.

This result finally caused the cheers that had been suppressed in everyone's throats to burst out:

"Great, we succeeded!"

"With magnetohydrodynamic propulsion, our atomic submarines will definitely be more powerful!"

"Not only that, but there are also the anechoic tiles and anechoic coatings that Consultant Li brought this time. When our country's atomic submarine is successful, we will definitely surpass Emperor M and Big Brother!"

……

Tears welled up in everyone's eyes, as if they had already seen the day of success.

If it were just a magnetohydrodynamic thruster, they might not be so happy.

After all, the gap in submarine technology between Xia Kingdom and the M Empire and Big Brother cannot be made up by just one technology.

What’s more, their sonar can’t detect it. Could it be that Emperor M and Big Brother’s sonar can’t detect it either?
Now, however, they not only have magnetohydrodynamic thrusters, but also anechoic tiles and anechoic paint.

This gave them greater hope.

……

Amid cheers that resounded through the sky.

Li Mu, on the other hand, was relatively calm.

He was also aware of the current state of Xia's sonar technology.

In the research of anti-submarine radar, they are still at a very backward level and need to continue to make in-depth efforts.

Just as he was concentrating on thinking.

Lin Fei, who had just finished applauding Huang Weilu and the entire testing team, asked curiously:
"Advisor Li, the test was successful, but you don't seem very happy."

He just finished speaking.

Upon hearing this, Wu Jinguang, Xiao Ruilin, Ding Xiuxun and others around him immediately looked over.

"It's not that I'm unhappy, I just feel that I have a long way to go." Li Mu smiled and said:

"And our country's anti-submarine technology is still a little inadequate."

"Just because we can't detect sonar waves doesn't mean Emperor M and Big Brother can't detect them."

His words made everyone's happy expressions fade a little.

Although it is a bit heartbreaking, it is indeed the fact.

"Why don't we find an opportunity to send the 033A to the South China Sea for testing?" South China Sea Navy commander Xiao Ruilin suddenly said.

they do not.

Then borrow it.

Anyway, there are always fleets coming and going in the South China Sea, so it’s not a bad idea to use them for testing.

Lin Fei's eyes lit up and he said, "Hey, Lao Xiao, your idea is really good. I think it will work."

If it works.

It will definitely make Emperor M and the transport captain drop their jaws.

"We still need to discuss it carefully before making a decision. This matter is not a trivial matter. If we are not careful, it may cause an international dispute." Beihai general Wu Jinguang said.

His words calmed Xiao Ruilin and Lin Fei down a little.

But I still insist on this idea in my heart.

They don't really want to fight.

Just to do an experiment.

The Xia Kingdom does not want to fight.

Emperor M may not want to fight.

The other side is busy competing with Big Brother, plus they recently gave Ah San a good beating and showed off their "muscles".

Unless their submarines really steal the opponent's aircraft carrier, they will not easily start a fight.

The more they thought about it, the more feasible it seemed.

Although the others did not speak, most of them thought this was a good idea.

Seeing this, Li Mu was a little amused and said:

"Leaders, there is no need to do this."

"I have other ideas."

"Our anti-submarine technology is backward, so why don't we improve it?"

His words stunned Lin Fei and the other two.

promote?

No matter how you put it, their current anti-submarine technology is far inferior to that of Emperor M and Big Brother.

"Consultant Li, we believe you can do it, but time waits for no one," said Lin Fei.

Hearing this, Li Mu smiled slightly and said:

"I know, but it won't last long."

"The Radar Research Institute in Kyoto now has a new type of pulse Doppler radar."

"Based on this technology, we can develop an anti-submarine radar that is no less powerful than, or even better than, the M Emperor and Big Brother."

After his words.

Everyone's eyes paused slightly, with different expressions.

The Radar Research Institute has developed a new type of pulse Doppler radar, but how did Li Mu know this news?
Also, can pulse Doppler radar be used in anti-submarine radar?

How come they don't know?
Suddenly, Huang Weilu showed an incredible expression and said:
"Does the success of the new pulse Doppler radar have anything to do with you..."

After hearing what Huang Weilu said, everyone reacted quickly.

It is impossible for ordinary people to know such important confidential information as the new pulse Doppler radar.

Those who know about this are either relevant scientific researchers in this field, such as them.

Or someone who has participated in the research.

One of the two must be true.

"I am indeed fortunate to have made some contribution." Li Mu nodded slightly and said.

This answer made everyone look surprised.

Their understanding of Li Mu, apart from the fact that he is the inventor of magnetohydrodynamic propulsion, is actually not much more than outsiders.

Huang Weilu exclaimed:

"I didn't expect that Consultant Li would have such in-depth research on radar!"

"A new type of pulse Doppler radar. I'm afraid even Emperor M and Big Brother don't have this technology yet!"

"If you were to develop anti-submarine radar, our country would surely be able to catch up and achieve a breakthrough from nothing to something better!"

He wasn't trying to be complimentary.

But he felt from the bottom of his heart that Li Mu could accomplish this task.

After all, since they can even develop a new type of pulse Doppler radar, it will definitely not be a problem to develop an anti-submarine radar.

It’s not easy, but at least there is a great possibility of success.

Just as he exclaimed in admiration.

After listening for a long time, Lin Fei, Xiao Ruilin and Wu Jinguang finally reacted and said:
"So, Consultant Li, can you develop a powerful anti-submarine radar for us?"

"Wow, you are amazing! You have only been here for a short time and you have already come up with three creative inventions!"

"When Governor Wu Xue told me about this before, I didn't believe it. I didn't expect it to be true. This is really great!"

……

The three of them were talking to each other, their faces full of excitement.

After all, as a naval general of the Xia Kingdom, it is quite frustrating.

Emperor M and Big Brother would come to their territorial waters from time to time and perform various provocative behaviors.

There is also the transport team leader, who also follows suit and takes advantage of the power of others.

How could they not feel angry when they were being looked down upon like this?

But there is nothing you can do no matter how upset you are.

The current strength of Xia Kingdom’s navy is still too weak, and it is difficult to pose an effective threat to Emperor M and Big Brother’s fleet.

Attack rashly, it would be good if you win.

If it fails, it will be a heavy blow to the Xia Kingdom’s navy and international influence.

To sum it up in two words - frustrating.

To the end.

Lin Fei said directly:
"Advisor Li, why don't you stay with our navy and develop weapons and equipment for us!"

"I believe that as long as you are here, our naval power will undergo a major transformation in a few years!"

"Then we won't have to endure the bullying from Emperor M and Big Brother anymore!"

His words made Wu Jinguang and Xiao Ruilin look at Li Mu with anticipation.

Ding Xiuxun and others in the surrounding stands also fell silent.

Everyone's eyes were filled with hope.

An anechoic tile, an anechoic paint, an anti-submarine radar, plus the magnetohydrodynamic propulsion system that is now equipped on the Type 033A submarine.

This guy is a natural submariner.

If they can be brought over, Xiaguo's submarine research can be accelerated by at least 5 years! !

"This... General Lin, thank you for your interest in this. Unfortunately, I have more important research in Kyoto." Li Mu shook his head helplessly and said.
