The Red Era, the Opening University Speech

Chapter 443 Anechoic Tiles and Anechoic Paints
Li Mu said:
"Let's talk about the anechoic tiles first. In fact, this thing is, to a certain extent, a successor to the synthetic rubber bionic material technology of 'Aliberich'."

“But they are not the same.”

"The former is made of high molecular weight polyisobutylene homopolymer and has a thickness of about 30 mm. The sound-absorbing tiles are mainly made of rubber or synthetic polymers and are usually around 7 cm thick..."

Ding Xiuxun and Huang Weilu listened patiently to Li Mu's explanation.

When Li Mu said "7 centimeters", the two were stunned for a moment, but did not interrupt.

Until it's over.

They then asked the question: "Is 7 centimeters too thick?"

"It's not thick. It may be a bit heavy for ordinary submarines, but it is just right for nuclear submarines." Li Mu said.

Anechoic tiles are not intended for use on conventional-powered submarines.

Huang Weilu suddenly realized what was going on when he heard this, and quickly said, "So that's how it is. I was thinking the wrong thing."

With the power source of an atomic-powered submarine, let alone 7 centimeters, even if it is twice as thick, it can be pulled, but the speed will be slower.

Li Mu then introduced the sound-absorbing paint:

"This material is a coating whose main components include rubber, ceramics and polymers, which can significantly reduce the noise of the submarine itself."

"If we can develop anechoic tiles and anechoic coatings, and add magnetohydrodynamic propulsion."

"In theory, it is basically impossible for existing sonar and other equipment to detect our submarines."

After he finished speaking.

Ding Xiuxun and Huang Weilu, who had been listening with great interest, were so shocked that they stood up from their seats.

With a "bang", the two men's heads made intimate contact with the roof of the car.

This huge reaction startled Jiang Zhe, who had been sitting in front and listening for a long time, and he quickly asked:

"What's wrong with you guys?"

However, neither Ding Xiuxun nor Huang Weilu responded immediately. Instead, they stared at Li Mu and said:

"Advisor Li, how confident are you?"

Not detectable by sonar and other equipment.

If this can be achieved, even if their submarines lag behind those of foreign countries in all aspects, they will still be able to have a strong voice in the ocean.

After all, no matter how advanced a ship is, it cannot withstand a close-range attack.

They are even capable of fighting against Emperor M's aircraft carriers.

At worst, I can die for the country and fight the enemy in a submarine. I won't lose anyway.

"Probably 5%, but the effect is only theoretical. The specific extent can only be determined after it is completed." Li Mu said.

He didn't say too much.

However, Ding Xiuxun and Huang Weilu didn't care at all.

Not to mention 5%, even if it's halfway, this technology is definitely worth pursuing.

……

The time for everyone to talk.

The convoy also arrived at the Baltic Shipyard.

When you get off the car, you can see a large group of low buildings.

Looking around, it covers a very vast area.

But Li Mu didn't have time to look for too long.

He was pulled into the factory by Ding Xiuxun and Huang Weilu, who were about to start discussing the development of anechoic tiles and anechoic coatings with him.

After Jiang Zhe, who was sitting in the passenger seat, got out of the car, he was about to introduce the history of the Bohai Shipyard to Li Mu.

When I turned around, I found that the three of them were almost at the gate.

Seeing this, he didn't care about his image anymore and hurried forward, saying:
"Director Ding, Professor Huang, I know you are dedicated to research."

"But we invited Consultant Li to come and participate in the test."

"Even if we want to study it, at least wait until the test is over. There's no need to be so anxious."

As he spoke, he winked at Ding Xiuxun and Huang Weilu.

That's not how it works.

Now that we have finished discussing the issue, Li Muyi will just run away after taking the test.

"It's just a test. Compared with research, it's not important at all." Huang Weilu simply shook his head.

Ding Xiuxun who was beside him also said:

"Leader, you may not know the importance of these sound-absorbing tiles and sound-absorbing paints."

"I can tell you responsibly that once it is successfully researched."

"Even if our country doesn't have atomic submarines, we can still compete with the ace fleets of Emperor M and Big Brother!"

Jiang Zhe listened to what the two said and stood there in a daze for a moment.

He may not be aware of how great the material is.

But to say that it can fight against the fleets of Emperor M and Big Brother is too intuitive.

How powerful is Xia's navy? Not to mention Emperor M and Big Brother, even Big Ying and France are difficult to deal with.

"They are just two kinds of materials. Are they really so powerful that they can enable our country's submarine technology to develop so much all of a sudden?" Jiang Zhe asked in disbelief.

Ding Xiu patrolled the road:

"Of course not. It's just that he is invincible in terms of 'invisibility'."

"But this is enough."

"Just think about it, if our submarines can evade enemy detection, how much of a threat they can pose when they launch an attack!"

After he finished speaking.

Jiang Zhe was stunned at first, then he understood everything.

If only it were possible to avoid enemy radar detection.

Then all it takes is a "cheap" submarine to destroy an enemy's expensive, technologically advanced, and powerful aircraft carrier.

Of course, it's not that he doesn't care about the lives of the soldiers.

"If that day really comes, I will be the first to rush up in a submarine." Jiang Zhe murmured.

Hear their conversations.

Li Mu was a little amused and said quickly:
"Leader Jiang, Director Ding, Professor Huang, not really. It hasn't come to this yet."

"We research and develop powerful science and technology to reduce sacrifices."

"If the soldiers are still required to fight to the death, I might as well not research anechoic tiles and anechoic coatings."

He did think about swapping submarines and aircraft carriers, but it was just a thought.

Perhaps the result is indeed good and worthwhile.

But in his eyes, human life is more precious.

"Haha, Consultant Li, don't worry, we are just talking. Besides, even if we want to go, it may not be our turn." Jiang Zhe said with a smile.

If there really was such a glorious opportunity, don't say he was the county governor.

Even if the chief judge comes, he has to stand aside.

After all, this is a rare opportunity to be recorded in history and remembered by future generations.

……

The four of them walked into the venue while talking.

In the end, Ding Xiuxun and Huang Weilu were unable to directly drag Li Mu to start the research.

After all, no matter how urgent it is, you have to ask someone to settle it down first.

So they took Li Mu to the dormitory first.

As he went upstairs, Ding Xiuxun introduced:

"This building has two floors. Your room is in the middle of the second floor. Comrade Guan and Comrade Zhao live next to you."

"There are two guards at the door at all times. You can tell them what to do if you need anything."

"Oh, by the way, Professor Huang, the rooms of some experts and professors in the institute are on the lower floor. If you want to find them, just go downstairs."

As he finished speaking, he walked to the door of the room.

Open the door.

The dormitory layout inside is simple yet stylish.

It looks a bit simple, but it has everything it needs. There is even a thick stack of manuscript paper on the desk for use at any time.

"Thank you, Director Ding, for your trouble." Li Mu nodded slightly, very satisfied.

He doesn't have any requirements for living, as long as he lives comfortably.

Ding Xiuxun smiled and said:
"As long as you are satisfied, Consultant Li."

"Well, you and your comrades will take a rest for a while."

"I'll call up all the comrades in our factory to come over and meet you."

After saying that, he stood up and prepared to leave.

Originally, there was no meeting included in Li Mu's hospitality.

After all, the main task of all researchers at the Baltic Shipyard is to develop atomic submarines.

The success of 033A is a happy event, but it is far less important than the atomic submarine.

Therefore, only Huang Weilu, the original chief designer of the Type 033 submarine, accompanied him.

But it's different now.

The emergence of anechoic tiles and anechoic coatings is definitely an important research project no less important than atomic submarines and must be taken seriously.

Moreover, he also needs to report this matter to his superiors.

……

Kyoto, National Science and Technology Commission.

Shortly after Li Mu arrived.

A secret telegram was sent over quickly.

Learned that the people arrived safely.

Everyone couldn't help but breathe a sigh of relief.

After all, what happened in Fengtian happened not long ago.

Although they are 99% sure, Emperor M and Big Brother will not act rashly again.

But I’m just afraid of that one chance.

Especially on trains, there are guards patrolling along the way.

But with a distance of more than a thousand miles, it is still very difficult to ensure absolute safety.

"It's good that we've reached safety!" Qin Feng put down the telegram, and the stone in his heart fell.

Just when he was about to pass the news to his superiors.

Suddenly, the secretary came back.

The latter held a copy of the latest telegram and said:

"Leader, there's new news from Bincheng. Tell me, tell me..."

The secretary's voice seemed to be stuck by something, and his brows were furrowed tightly, revealing an extremely conflicted expression.

Seeing this, Qin Feng was startled, thinking that Li Mu had an accident, and quickly stood up and said:

"say what?"

The secretary took a deep breath and continued:

"It says that Advisor Li proposed two new technologies. If they work, we might be able to replace aircraft carriers with submarines."

"What did you say?" Qin Feng was dumbfounded for a moment, and even suspected that he had heard it wrong.

Submarines for aircraft carriers?
It all sounds like a joke.

Although he had never seen an aircraft carrier in person, he had seen it in photos and it was definitely a tough giant to deal with.

The other party passed through the Xia Kingdom's strait unscrupulously as if they were in an empty land.

However, they can only continue to condemn and cannot take any countermeasures.

Why? Because you can’t beat him even if you fight.

"It's true, take a look." The secretary handed over the telegram.

In fact, he also suspected that he had seen it wrong.

After all, replacing submarines with aircraft carriers is really too incredible.

Even if he knew nothing about military affairs, he knew the gap between the two.

Qin Feng took the telegram, read its contents word by word, wiped his eyes several times, and finally confirmed the news.

However, the telegram directly stated that Li Mu proposed two materials, which enabled them to have the possibility of exchanging submarines for aircraft carriers.

Other details were not mentioned.

After putting down the telegram, he looked towards the northeast and couldn't help but sigh:
"Li Mu, Li Mu, you have such a powerful thing, why don't you take it out earlier? Tell us after everyone leaves!" After the "complaint".

Qin Feng quickly sent someone to Bincheng to verify the news as soon as possible and continue to bring back more detailed information.

Afterwards, he hurriedly left the unit and headed for a small courtyard.

After the notification.

The secretary took him in.

After meeting his superior, he immediately reported the "submarine-for-aircraft-carrier" matter.

After listening.

The superior was so happy that he stood up and slapped the table twice with his palms, saying:

"If this is true, then we will have the confidence to fight against Emperor M and Big Brother's fleet in the future!"

There is a reason why he is so happy.

Since the establishment of the New Xia Kingdom, the warships and aircraft of the M Empire have been constantly invading the territorial waters and airspace.

Although they have been issuing warnings, there has been little effect.

As of April 62, Xia State had issued a total of 4 serious warnings.

If it weren't for the invention of the new pulse Doppler radar, they would have been able to shoot down the U-2 high-altitude reconnaissance aircraft of the U.S. Empire in one fell swoop, making the U.S. Empire fearful when invading its airspace.

This number may be even higher!
"Leader, I think this is an opportunity. If we can deal a head-on blow to Emperor M's fleet, it will be of great help in maintaining our country's territorial security and enhancing our international status." Qin Feng suggested.

When I saw the telegram.

A plan emerged in his mind.

Hearing this, the superior leader paced for a while, and then said:

"I know what you're thinking, but this matter needs to be handled with extreme caution."

"Our country's primary goal now is development rather than war."

"I agree with the plan. It is equivalent to giving us a very deterrent trump card, but it must not be used unless it is absolutely necessary."

The Xia Kingdom is currently thriving, so there is really no need to fight a war.

And the fight is against the superpower, Empire M.

As long as they don't go too far, you can provoke them, but sooner or later, they will pay you back a hundred or a thousand times.

"I think so too. The plan is just a guarantee. I believe that Li Mu will be able to create more powerful weapons in the future, and there is no need to use such extreme methods to achieve victory." Qin Feng said with a smile.

He actually didn't want to sacrifice the lives of the soldiers.

But this is indeed a helpless act.

There is constant friction between Emperor M and Big Brother, and they may fight at any time.

It's better to keep a few trump cards in hand. If the opponent's aircraft carrier fleet really comes, you can't just sit there and wait for death.

……

Baltic Shipyard.

Li Mu didn't know that he had just simply packed up his dormitory.

A military plan has been drafted and is now under discussion.

As for whether it is possible that something cannot be done?
No one doubts this.

——How could Li Mu not be able to do it?

Moreover, the plan was named "Submarine for Aircraft Carrier", which is simple and direct.

The Xia Kingdom is not afraid that Emperor M or Big Brother will know about this plan.

After all, it sounds outrageous.

What's more, they were afraid that the two of them didn't know.

After all, it is still a bit difficult to make them believe that Xia State has the ability to complete this plan.

……

After leaving the dormitory.

Accompanied by Huang Weilu, Li Mu came to the auditorium of the Baltic Shipyard.

At the gate, Jiang Zhe and others were waiting outside.

A banner that read "Welcome Consultant Li Mu to visit" was hung in the sky.

He walked up to them, said hello, and then walked into the auditorium.

Once inside.

Hundreds of eyes inside looked over at once.

After confirming that it was him, everyone couldn't help but show excitement in their eyes.

A group of experts and professors wearing blue and khaki cotton coats surrounded Li Mu and greeted him excitedly.

"Hello, Consultant Li, I'm Zhao Renkai, it's an honor to meet you!" The speaker was a middle-aged man in his forties with a very handsome appearance.

Li Mu had seen the other party in the development history of Xia State's submarines.

A famous atomic power expert in Xia State, one of the founders and pioneers of atomic power science and engineering technology research and design.

He has done a lot of work for the technological development of atomic power for Xiaguo's submarines and achieved remarkable results.

The other party just finished his introduction.

Without waiting for him to shake hands and say hello.

Another professor stepped forward and said:

"Hello, I'm Li Yichuan, and I have always admired you very much!"

Li Mu looked at the other person.

This person's achievements are not that high.

However, it was not because of lack of ability, but because he died too early.

Due to his long-term selfless work, he died at the age of 40 at the test site of an atomic submarine.

I have to say, it is a huge pity.

Just as he was sighing.

Another large group of experts and professors came forward to introduce themselves to him.

He knew some of these people and could find them in history books or later materials.

But most of them are unheard of.

However, the lack of fame is not necessarily due to the low achievements, but more likely because the contribution is too great and cannot be announced to the outside world.

After everyone showed their faces in front of him.

Li Mucai slowly said: "Dear experts and professors, it is my honor to meet you!"

This sounds like a polite remark.

However, this is what he wanted to say most at this moment.

He always maintained the highest respect for every scientist who dedicated his life to the defense of Xia State.

Without them, there would be no happiness, well-being and peaceful days in the future.

"Advisor Li, your words are too polite. Let's sit down first and talk." Seeing this, Jiang Zhe pulled Li Mu to sit on the stage in the auditorium.

Afterwards, Ding Xiuxun, Huang Weilu, Zhao Renkai and others took their seats in turn.

As a welcome party.

Speaking is a must.

But Jiang Zhe knows himself well.

This is not the time to speak official language.

So he said a few simple words to express Bincheng's welcome to Li Mu, and then quickly handed the microphone to Ding Xiuxun beside him.

However, the latter did not follow the routine at all and said directly:
"I'm sure everyone has heard about the sound-absorbing tiles and paint."

"I won't waste any more time."

"Counselor Li, how about you say a few words?"

Before he could finish his words, the microphone in his hand was already handed to Li Mu.

Other factory leaders, as well as Huang Weilu, Zhao Renkai and others, did not show any dissatisfaction when they saw this. Instead, they felt that it was reasonable.

In their hearts, research always comes first.

Li Mu looked at the microphone in front of him.

He looked at the eyes of Ding Xiuxun and others, as well as the eyes of the researchers below, and felt quite helpless.

He said slowly:

"In fact, these two materials are still in the theoretical stage."

"I proposed this because I wanted to exchange ideas with experts and see if it is possible to achieve it."

"Don't expect too much from it. After all, it's just an auxiliary technology and is not as important as an atomic submarine."

After listening to Ding Xiuxun and Jiang Zhe's ideas.

He was really worried that after the higher-ups got to know the news, they would be so upset that they would go to Emperor M or Big Brother to fight to the death.

After all, in this era, Xia’s navy was indeed too weak.

Not to mention dealing with Emperor M's fleet, it would be difficult to even create enough of a threat.

Of course, there are also reasons why some people do not want to take the initiative to provoke disputes.

But not wanting to fight is one thing.

Whether or not you can win the fight is another matter.

Apart from anything else, those who often wander around Xia Country’s territorial waters are not only Emperor M and Big Brother, but also the transport captain.

Just when Li Mu was feeling emotional.

Ding Xiuxun on the side said directly:

"Advisor Li, you are too modest!"

"As long as the anechoic tiles and anechoic coatings are successful, it will definitely be of great benefit to the development of our country's submarine industry!"

"Even if we don't have atomic submarines by then, Emperor M and Big Brother will still be wary of us!"

After he finished speaking.

The researchers below were immediately excited.

After all, they only knew that Li Mu brought two new types of materials that could eliminate the sonar waves of submarines.

However, I don’t know how effective it will be.

Now it seems that with this thing, their submarines can compete with Emperor M and Big Brother.

Thinking of this, they immediately said:

"Director, please tell me, what's going on?"

"Yeah, how can we make Emperor M and Big Brother afraid of us?"

"Could this anechoic tile and anechoic paint make the submarine completely 'invisible' so that their sonar can't hear me?"

……

Everyone asked questions one after another.

Been studying on submarines for so long.

They knew too well the technological gap between Xia Country and Emperor M and Big Brother, and it was impossible to catch up in a short period of time.

But this sound-absorbing tile and sound-absorbing paint.

But it gives them the possibility to compete with it, which makes people curious.

Ding Xiuxun on the stage saw this, looked at Li Mu and said:
"Would you like to explain it to everyone again?"

Hearing this, Li Mu looked down at the pairs of eyes that were looking at him expectantly.

What else can he do? Just tell me.

……

It took 10 minutes.

Li Mu briefly introduced the principles, structures and other aspects of sound-absorbing tiles and sound-absorbing coatings.

Of course, this is not what everyone is most concerned about.

It’s the effects they can achieve.

Submarines will inevitably produce noise when sailing in the ocean.

This noise, once detected by sonar, will reveal its location.

Once it can be eliminated to a certain threshold, it will be possible to become "invisible" in the enemy's sonar and approach the opponent silently.

However, some people have doubts about this.

After Li Mu finished speaking.

An old researcher immediately raised his hand and asked:
"Advisor Li, the noise generated by conventional submarines is greater than that of atomic submarines. Can the use of anechoic tiles and anechoic paint also achieve the effect of 'stealth'?"
