The Red Era, the Opening University Speech

Chapter 475: It's not that I'm quitting, it's that I'm doing it well
"Good news?" Li Mu looked at Guo Mo who was smiling happily.

He looked at Ding Xiuxun who was sitting next to him.

After pondering for a moment, he asked tentatively:

"Could it be that our navy has recently taken action against the transport captain?"

Li Mu's words had just fallen.

Ding Xiuxun on the side laughed and said:

"I told you he could guess it, Dean Guo, your box of tea will belong to me later!"

"Okay, it's yours." Guo Mo waved his hands distressedly and said helplessly, "It's weird, how did you guess it so quickly?"

"You've kept Director Ding here, so how could I not guess it?" Li Mu said, not knowing whether to laugh or cry.

But after laughing.

He couldn't help but feel a little worried, and said:
"President Guo, I suggest that we should put this plan on hold for a while. It would be best to wait until the new sonar is available."

The transport captain is easy to deal with.

But once the action is taken, there is no guarantee that Emperor M will interfere.

Although he has confidence in magnetohydrodynamic propulsion.

But since it concerns the lives of the soldiers, he still hopes to be more cautious.

"Look at me, I forgot to say it. The Type 033A submarine is equipped with the latest anechoic tiles and anechoic coatings, plus magnetohydrodynamic propulsion, so there will definitely be no problem." Guo Mo said.

Although it is only a preliminary success, there is still room for improvement in the effectiveness of sound-absorbing tiles and sound-absorbing coatings.

But it was unanimously agreed that the plan could be implemented.

no way.

If they don't teach the transport captain a lesson, they will really think that Xia's coastal waters are their backyard where they can enter and leave at will.

And they are not without basis.

Guo Mo continued:
"The transport captain's side mainly includes the freshwater Carp-class submarines and Sea Lion submarines provided by the M Emperor."

"Both of these submarines have generally fallen behind the world's advanced level."

"Our Type 033A submarines have greater advantages in both technology and actual combat. As long as we fight quickly and decisively, we can achieve great results."

He understood Li Mu's concerns.

But the above has indeed been considered comprehensively.

In addition to deterring foreign fleets that brazenly invade their territorial waters.

Another thing is to show their current strength to the Western world.

The Xia Kingdom has been a little too dazzling during this period.

Without a display of strong force.

It will only make Western countries feel weak and vulnerable.

"What you said may make sense, but I still stick to my opinion. I hope you can convey it to the higher-ups on my behalf." Li Mu continued.

He understood the idea.

You know, there will always be casualties in war.

But a person's life is also life.

He hopes to minimize unnecessary sacrifices whenever possible.

Think of this.

He continued:

"Well, give me five days and I'll come up with a new type of sonar."

Submarine warfare.

Whoever discovers the opponent first often has the upper hand.

Although even if they discovered Emperor M's submarine, they might not be able to defeat it.

But at least it can be discovered in advance and a fight can be avoided.

"Five days?" Ding Xiuxun on the side couldn't help but widen his eyes.

He even suspected that there was something wrong with his ears.

I couldn't believe that the time I heard was real.

It’s crazy to develop a new type of sonar in 5 days!
Guo Mo also couldn't believe it and said:

"You really didn't say it wrong. It was 5 days, not 5 weeks?"

"I originally wanted to develop the shore sonar array first, but since the higher-ups want to promote the country's prestige, it wouldn't be a big problem to develop a new type of sonar first," Li Mu explained.

Taking the initiative was not a particularly wise choice in his opinion.

After all, in the original history, the Xia Kingdom relied on long-term stable development to become stronger step by step.

Now with his arrival, many things have changed.

At least on this point, he doesn't expect much to change.

Of course, it all comes down to the fact that the fist is not big enough.

Only when the Wulong-1 fighter jet is produced will they have the confidence to speak.

"In that case, I will report to the higher-ups and then ask the Radar Research Institute to fully support your research!" Guo Mo said decisively.

Military action against the transport captain is imminent.

They have to race against time.

Only then can we develop the new sonar before taking action.

This is not enough.

New sonars always have to be tested before they can be used with confidence.

Even if they believe in Li Mu, they cannot skip steps.

So the time left for them may not even be even half a month.

……

After deciding on the direction.

Li Mu quickly said goodbye to Guo Mo and Ding Xiuxun, and then came to his office in the Chinese Academy of Sciences.

Sit at your desk.

He took out paper and pen and began to organize the information.

The development must be completed within 5 days.

Then the whole plan cannot have any mistakes.

It even has to be done to the point where trial production can begin as soon as the product is handed over.

"Let's choose a target first." Li Mu took a deep breath and calmed himself down.

It's urgent.

But you can't make mistakes.

Otherwise, we would be playing with the lives of the soldiers.

The most advanced submarine sonar of the M Empire is the AN/BQQ-2 sonar, which has a detection range of tens of kilometers or even farther.

Want to deal with it.

The new type of sonar required needs to have a detection range of at least over 100 kilometers.

Open the chat page.

After searching for more than half an hour.

Li Mu finally found his target:
"H/SQ2-262 sonar, this is good."

This is a sonar developed by Xia Guo in the 80s.

The detection range exceeds 100 kilometers, which is better than the detection range of AN/BQQ-2 sonar.

Moreover, it is not only applicable to conventional submarines, but also to nuclear submarines.

Although the technology may not be that advanced.

But it is enough to meet Xiaguo’s current needs.

Thinking of this, Li Mu started writing immediately.

……

Around 10pm.

Li Mu was still writing furiously in the office.

See this scene.

Guan Jianmin and General Zhao, who were waiting outside the door, could no longer contain their excitement.

But just when the two wanted to step forward to remind them.

But he was stopped by Guo Mo, who said:
"Don't disturb him at a time like this!"

“5 days, 5 days to create a new type of sonar!”

"If he hasn't finished in another hour, I'll go get him myself!"

Although he was also worried about Li Mu's health.

But I know more about what is most important to me now.

"President Guo, what if he continues to study without sleep for the next five days? Shouldn't we stop him?" Guan Jianmin asked anxiously.

After being reminded many times by the leaders above.

He had rarely seen Li Mu working like this.

General Zhao on the side did not say anything, but just looked in the direction of Li Mu, his eyes full of admiration.

As a friend, he hoped that Li Mu would not try so hard.

But as a soldier, he hopes that Xia Country can have this new type of sonar to avoid more comrades being sacrificed in the war.

"Of course we have to stop him. Oh, never mind. I'll go talk to the higher-ups." Guo Mo sighed, turned around and left.

I can’t persuade Li Mu.

We can only persuade the higher-ups.

Looking at the current situation, he felt that the latter might be easier.

Just as he turned around and was about to leave.

suddenly.

The sound of a chair being dragged was heard in Li Mu's office.

heard movement.

Guo Mo, Guan Jianmin and Zhao Canjun, who were standing outside the door, immediately looked over at the same time.

Li Mu suddenly stood up from his seat, holding a stack of manuscript paper two fingers thick, and flipping through it quickly.

See this scene.

They all held their breath at the same time, not daring to disturb him in the slightest.

Even if someone passed by, they would quickly stop them to avoid disturbing Li Mu.

……

About 10 minute passed.

Li Mu finally finished turning the last page of the manuscript and breathed a long sigh of relief.

I was just about to go to Guo Mo with the plan.

Then I heard a noise coming from outside.

Seven or eight people suddenly squeezed in from outside his office.

Except Guo Mo, Guan Jianmin and Zhao Canjun.

There are also Tang Yanjie and Wang Shicun who I haven’t seen for a long time.

But before they could speak.

Guo Mo quickly stepped forward and criticized seriously:
"You, you're in the same old trouble again, aren't you?"

"There must not be a next time, understand?"

"If you continue like this, even if the new radar issue is urgent, I will punish you by making you take a rest!"

His tone was very stern.

Hearing this, Li Mu smiled and said:
"Don't worry, it's just today, it won't happen again."

"Really? You're so obedient? You're not going to do it now?" Guo Mo instantly showed a suspicious expression.

After all, he said this before.

The two of them would definitely have a fight, and Li Mu would try to make out that even if he was wrong, he was right.

Since I was right this time, he just nodded so obediently?

Li Mu smiled and said:

"It's not that I'm not doing it anymore, it's that I'm doing it well."

“Oh, is that so…?” Guo Mo didn’t react for a moment.

It wasn't until I thought about this carefully that I suddenly realized something was wrong.

Done?
No, a normal person may not be able to find an idea in an afternoon!
Even though he already had some understanding of Li Mu's abilities and talents.

Guo Mo still couldn't hide his shock and said:

"You mean you invented a new type of sonar in just one afternoon?"

When everyone heard Guo Mo's words, they all fell silent.

They looked at Li Mu, their eyes full of disbelief.

an afternoon.

Just developed a new type of sonar?
This sounds almost as outrageous as the rumor that Big Brother has alien technology.

"I can't say there are no problems at all, but it's worth a try." Li Mu rubbed his swollen eyebrows and said.

The long hours of intensive work were very exhausting for him.

We need to develop the sonar of the 80s in advance.

There are so many things to consider, and these 200 pages of manuscript can only barely make them clear.

Guo Mo looked at the tired Li Mu and said immediately:

"Okay, I'll go report to the higher-ups first."

"Then this plan will be sent to the Radar Research Institute as soon as possible."

"But you have to promise me that you will go back and rest right now."

an afternoon.

No, to be exact, it was only about 6 hours.

The plan for the new sonar was completed. It was terrifying to think how much effort was put into it.

"I'm fine. In fact, I already had an idea of ​​most of the contents of the plan, but I just didn't have time to organize it." Li Mu said.

He also knew that this time he had gone a bit too far.

But it's not impossible to find a reason.

After all, he had already proposed the development plan for the shore-based sonar array system.

Guo Mo said with a smile:
"Even if you say it to hell, you have to go back and rest tonight."

After he finished speaking.

Guan Jianmin and General Zhao, who were standing by, also advised Li Mu to rest for a night before making any further comments.

I saw everyone trying to persuade me.

Li Mu had no way to continue insisting, so he had to nod helplessly and agree to go home and rest.

……

Early next day.

Wash up after exercise.

Li Mu took a car and went directly to the Radar Research Institute.

to the place.

He went straight to the director Peng Shilu.

The latter's eyes were bloodshot, and it was obvious that he had been up all night.

But even so, his eyes were still full of excitement.

Seeing Li Mu coming over, he said happily:

"When Dean Guo told me this, I thought he was teasing me. I didn't expect you to come up with a new type of sonar in such a short time!"

"It's just a helpless act." Li Mu shook his head.

If it is not the plan above.

He hadn't originally planned to develop a new type of sonar so quickly.

Hearing this, Peng Shilu patted his shoulder and said:

"With this new type of sonar, I believe our soldiers will be able to defeat the enemy successfully!"

After Guo Mo sent the plan yesterday.

While requiring the Radar Research Institute to make every effort to develop a new type of sonar.

He was also informed of the whole story.

"Let's not talk about this. Director Peng, after reading the plan, did you encounter any difficulties?" Li Mu said.

Since the above decision cannot be changed.

Then all he could do was to get the new sonar out as soon as possible.

Only in this way can we provide an extra layer of protection when the plan is implemented.

Peng Shilu laughed and said:
“To be honest, there are definitely difficulties.”

"If it weren't for you, I'm afraid we wouldn't even be able to make a breakthrough in acoustic theory research."

"But now, everyone has given high recognition to your plan. Except for time, there is no problem!"

His tone was full of confidence.

Last night, experts and professors from the entire Radar Research Institute worked hard all night and fully verified the feasibility of the plan.

All that remains are the four words “work hard”.

"It's not enough to just understand the theory, we have to start the experiment as soon as possible." Li Mu nodded slightly and said.

He did not doubt the capabilities of the researchers at the Radar Institute.

But this task is indeed very heavy.

We have to race against time to get the new sonar out before the plan is implemented.

Peng Shilu nodded and said:

"Well, let's get started."

Having said that, he prepared to take Li Mu to the laboratory.

But he had just taken two steps.

As if he remembered something, he hurriedly said:

"By the way, it says you should pay attention to your rest time..."

"Do you think it's appropriate for you to talk to me in your current state?" Li Mu looked at Peng Shilu, whose eyes were filled with fatigue, and said with a smile.

Hearing this, a trace of embarrassment flashed across Peng Shilu's face.

But soon, he became serious again and said:

"Okay, then I'll lead by example."

"I'll take you to the lab and I'll go rest."

"Don't even think about begging for mercy. It's useless."

As soon as he finished speaking, Peng Shilu walked out, not giving Li Mu any chance to speak.

……

Then, the two came to the laboratory.

Just walked to the door.

Then I heard a series of exclamations coming from inside.

Hear this sound.

Li Mu looked at Peng Shilu beside him in confusion.

The latter immediately explained:

"It should be Director Wang Dezhao from the Acoustics Research Institute who has arrived with his men."

"He is a famous physicist and acoustician in our country, and has made important contributions to the country's hydroacoustics and sonar technology."

"We were originally planning to ask them to come over to help with the shore sonar array system later, but we didn't expect it to be brought forward because of the new sonar issue."

As Peng Shilu spoke, he took Li Mu into the laboratory.

The moment the two appeared at the door.

Then he was discovered and shouted:
"It's Consultant Li, Consultant Li is here!"

The voice just fell.

Wang Dezhao and others, who were originally amazed at the new sonar solution, immediately turned around and looked at Li Mu, saying:
"You must be Consultant Li, I've heard of you for a long time!"

"Hello, Director Wang Dezhao!" Li Mu stretched out his hand and shook hands with the little old man in his 60s in front of him.

Don't look at the other person's age.

But he was one of the founders of hydroacoustics in the Xia Dynasty.

Wang Dezhao looked Li Mu up and down for several times before continuing:

"It's unbelievable. You said we all have the same brain, so how come you were able to come up with a new type of sonar in just one afternoon?"

"Moreover, the acoustic theory innovation involved has completely surpassed the advanced level of our country and even the world!"

"If the timing wasn't inappropriate, I would even prefer to ask you academic questions instead of doing research!"

His tone was full of admiration.

Xiaguo's acoustic theory basically relies on its big brother to barely keep up with the pace of world development.

This is especially true when it comes to sonar.

The sonars they mainly use to this day are still imitations of Big Brother's equipment.

For example, a simple sound wave propagation model is still used, and there is limited understanding of the propagation characteristics of sound waves in water.

There is also a lack of in-depth research on the impact of sound wave propagation in complex marine environments.

For example, analog signal processing technology, which relies on filters and amplifiers, is too simple to effectively separate target signals from environmental noise.

These problems are big and small, difficult and easy.

But if you want to conquer them one by one, it will be hard to see hope without three or four years of effort.

However, what he didn't expect was that this was explained in great detail in the proposal given by Li Mu.

To be frank, this has directly filled a gap in the domestic acoustics field that lasted for at least 10 years.

"It's just my superficial opinion. When it comes to acoustics, I'm still more at the theoretical level and lack the integration with practice." Li Mu said.

When facing an acoustic master like Wang Dezhao.

You should be humble when you should be humble.

After all, he had no problem with theory, but he was still far from perfect in practice.

Wang Dezhao laughed and said:
"What kind of question is that? I, Professor Ma, Professor Ying, and Professor Zhang all think that your theory has no flaws."

As his words fell.

Three professors from the Institute of Acoustics also came forward and introduced themselves to Li Mu.

Ma Dayou, a famous acoustician of the Xia Dynasty.

Ying Chongfu, an expert in ultrasound.

Zhang Renhe, hydroacoustics expert.

"Hello, professors." Li Mu walked up to the three of them and shook hands with them one by one.

After getting to know each other.

He was not vague and said immediately:
"Director Wang, time is of the essence and the country urgently needs this new type of sonar, so I won't say any more polite words."

"In order to complete the development of the new sonar as quickly as possible, we must start research as soon as possible."

"If you and everyone else are ready, let's get started right now!"

Li Mu's words were simple.

But it is the best mobilization.

The country needs it.

When these four words appear, they are better than any written mobilization speech.

Of course, there is also the further "It is time for D and the people to test us."

But Li Mu felt that it had not yet reached that point.

If this were to be said out loud, I'm afraid everyone would fight to the death!

Wang Dezhao and others were also unambiguous and immediately said in unison:
"Yes!"

……

Followed by.

Under the leadership of Li Mu, the development of the new sonar began immediately.

First, the tasks are divided, that is, into groups.

Wang Dezhao is in charge of the theory and basic research group on further education.

Their task is to study the theory of underwater sound wave propagation and establish a mathematical model of sonar performance.

Peng Shilu is in charge of the sonar hardware development team, and is responsible for researching the core hardware of the sonar system.

Including sound wave transmitter, receiver, array, etc.

The Marine Environment and Test Group is led by Ying Chongfu. It studies the impact of ocean and seascape on sonar performance and is responsible for sea trials.

The remaining ones are the Signal Processing and Electronic Technology Group and the System Engineering and Integration Group.

Li Mu carried it on his own shoulders.

He has a natural advantage in this regard, and no one can replace him.

……

In the conference room.

After everyone has taken their seats.

Li Mu picked up a small blackboard and said:

"Let me first talk about the four key technologies we need to overcome."

“First, there’s low-frequency sound wave technology.”

"Using low-frequency sound waves, which have less propagation loss in water, the frequency range may be hundreds of hertz to thousands of hertz..."

He started with low-frequency sound wave technology.

Then explain it step by step.

Digital signal processing, multi-array design and anti-interference technology.

Just as he finished speaking.

Wang Dezhao in the audience quickly raised his hand and asked:
"Advisor Li, the transmission and reception of low-frequency sound waves, signal propagation and attenuation, environmental noise interference, and digital signal processing, etc., all have great difficulties."

The transmission of low-frequency sound waves requires a high-power transmitter and a high-sensitivity receiver.

Moreover, although it can propagate over a long distance, it is still affected by attenuation and multipath effects in complex ocean environments.

Environmental factors such as sea water temperature, salinity, and humidity can significantly affect the propagation characteristics of sound waves.

Li Mu replied:

"In terms of signal transmission and reception, new piezoelectric materials can be used to develop high-efficiency, low-loss sound wave transmitters. The receiver uses signal amplification technology to improve reception performance."

"The propagation and attenuation of the signal requires the use of computers to build a model of the ocean sound field of the bluebird."

"I will develop adaptive signal processing algorithms to compensate for attenuation and multipath effects in sound wave propagation. Subject environmental interference noise..."

He doesn't speak very fast.

But the experts and professors from the Institute of Acoustics were still in a state of panic.

It is difficult for them to digest these contents directly at once.

After all, whether it is new piezoelectric materials, advanced signal development technology, etc.

It is all new knowledge and content for them.

The experts and professors at the Radar Research Institute were well prepared, so no one tried to understand it and instead just wrote down the content first.

But soon.

They discovered something was wrong.

After Li Mu finished speaking, he would give them some time to think.

This time, after solving several problems raised by Wang Dezhao.

Then he added three more points:
"Low-frequency sonar systems usually need to integrate multiple arrays, so we need to develop multi-array data fusion algorithms to achieve accurate positioning and tracking of targets."
