The Red Era, the Opening University Speech

Chapter 481 You are talking without any pain

No wonder Liang Shoupan was surprised.

The world's air-to-air D missile technology is still mainly based on semi-active radar guidance and infrared guidance.

As for active radar guidance technology.

It's just a concept now.

He is not optimistic about researching an immature technology.

Even if this person is the famous Li Mu.

"I'm not sure about that, but Consultant Li's ideas have been unanimously recognized by the experts and professors in your hospital. They believe in his ability," said Guan Jianmin.

Without revealing the specific content of the research.

He had dropped enough hints.

Liang Shoupan also reacted quickly.

The plan that can get the approval of Chen Yijian, Huang Ruisong and others at least has a certain degree of feasibility.

Of course, this alone was not enough to impress him.

After thinking for a while, Liang Shoupan said:

"Okay, I agree to meet with Consultant Li. I hope you can arrange it as soon as possible."

Even if the probability is only one in a thousand.

He felt that he should go and see the actual situation first.

"No problem." Guan Jianmin said.

……

The other end.

Li Mu visited five project teams including PILI-8, PILI-12 and LEITING-2.

It was already evening.

When he walked out of the meeting room.

I feel like my lips are almost peeling from talking so much today.

Fortunately, most of the theoretical problems have been solved, and the focus can be shifted to experiments.

"We still need to keep an eye on the PL-12. After all, it is a fourth-generation medium-range air-to-air D missile." Li Mu thought to himself.

The development of PL-12 began in the late 90s and was completed and tested in the early 2s.

It is mainly used for beyond visual range air combat, with a range of about 70-100 kilometers, depending on the launch altitude, speed and target maneuverability.

Especially the active radar guidance method.

After the D missile is launched, it can track the target autonomously without the need for the carrier aircraft to continuously provide guidance signals.

This guidance method can greatly improve the survivability and combat flexibility of the carrier aircraft.

But the better it is to use, the more difficult it is to develop.

There are four main issues.

Active radar seeker technology, materials and manufacturing processes, miniaturized high-performance rocket engines, guidance and control systems.

Li Mu can basically solve 3 of these points.

However, he needs to spend more effort on miniaturizing high-performance rocket engines.

The problems of thrust and combustion efficiency have been solved.

The solid fuel made from double-base modified propellants is sufficient to meet this need.

However, more efforts will be made to miniaturize and lighten the engine to avoid the problem of the D-bomb being too large and heavy.

"First, use CAD and finite element analysis to optimize the engine structure, remove unnecessary materials, and then consider integrated design." Li Mu began to plan.

In terms of miniaturization and lightweight, he would not copy the information of later generations.

After all, many future technologies and conditions are not yet available and cannot be copied completely.

Therefore, using CAD and finite element analysis to optimize the engine structure becomes a very critical step.

There is no need to say much about the former.

The more difficult part is finite element analysis.

This is a computer simulation design method that removes unnecessary materials by establishing geometric models, defining material correspondence, dividing the grid, applying solution conditions, and removing unnecessary materials through methods such as solving and analyzing.

However, their current software does not support the creation of particularly detailed three-dimensional models, which will be a difficulty for research.

"Not only the CPU needs to be upgraded, but also the GPU, memory, storage and distributed computing, there must be a major improvement." Li Mu said secretly.

The development of CAD software was not a problem for him.

After all, after Su Dongzhuang, Wang Shoujue has been following up.

He just felt it was a bit troublesome to upgrade so many things.

……

Go back to dorms.

Li Mu greeted his roommate, General Zhao.

He sat down at the desk and began to write the plan.

Given that Huang Xinhua is about to break through the 50w integration mark.

When he was designing.

The performance standards have also been raised accordingly.

First of all, high-resolution 2D graphics display is definitely a must.

This has been achieved.

This allows for fast window management, bitmap manipulation, and simple rasterization operations.

It also improves hardware-accelerated line drawing, polygon filling, and font rendering.

Then there's 3D graphics support.

Although the rendering quality and speed are still very limited, the resolution and effects of texture mapping are also relatively basic.

However, it is sufficient to deal with the problems of miniaturization and lightweight of solid rocket engines.

"Well, at this level, I can even play 3D games!" Li Mu suddenly thought.

This unrealistic idea was quickly put behind him.

Never mind the internet.

Even personal computers are not popular now.

Making 3D games is only possible if they have a lot of money to burn.

……

The next 3 days.

Li Mu stayed in the Aviation Academy, guiding Chen Yijian and others in the development of the D bomb.

Of course, besides that.

He also paid attention to the progress of core machine model manufacturing by Song Wencong.

This is a very critical link in the development of the AL-31FN engine core.

Models should not only be used to verify designs, but also help optimize performance and reduce R&D risks and costs.

For example, pneumatic models.

It is used to verify the aerodynamic design of compressors, turbines and combustion chambers.

Song Wencong and others did not disappoint him.

From aerodynamic models to structural models, thermodynamic models, control system models, and material and manufacturing process models, the progress has been very good.

……

On the fourth day.

Li Mu got up, washed and exercised.

Had breakfast.

As usual, he plunged into the laboratory, ready to continue his research work.

But his people haven't arrived yet.

Tang Yanjie stopped him and said:
"I got word from above that Big Brother has a new visiting group that's clamoring to see you, so he asked me to come over and ask for your opinion."

"I heard that quite a few authoritative experts from Big Brother have come here."

"If you don't want to go, I'll tell you not to let anyone disturb your research."

He knew how important Li Mu's research was.

"It's okay, I'd better go and meet him. I have other things to do." Li Mu smiled and said.

Since Big Brother’s people want to see him, then let him meet them.

It just so happened that all the research projects he was working on required a large amount of research funds to carry out.

Good talk.

Maybe you can even make some money from Big Brother.

……

Just leave.

That afternoon, Li Mu returned to Kyoto.

But he was in no hurry to meet Big Brother's delegation.

Instead, he went to Beijing Institute of Technology first and found Alexi at the game development center.

When the latter saw him, a hint of unnaturalness flashed across his face.

After all, he got the news from Li Mu and then told it all to Old Ivan and others. It was a bit unfair.

But what he didn't know was...

In fact, Li Mu didn't care at all.

Li Mu smiled and said:

"Professor Alexi, what are you busy with recently?"

"What else can we do? Continue to develop games. You don't know that this time we in China are planning to use "War 2" to compete with "Star Wars." Alexei said with a wry smile.

I don’t know what’s wrong with those people in China.

Perhaps he was jealous of the money Xia Guo made.

This time, the lion made a big request and proposed a task of selling 200 million copies of game cartridges.

Doesn't sound like much.

But the problem is that their last game "War" only sold 50 copies despite losing money.

It's not that he can't understand the idea of ​​making money.

After all, it's a market worth hundreds of millions of dollars every year, and everyone would be envious.

But let's at least take a look at our own strength.

Li Mu smiled and said:

"This is a good thing. Competition leads to progress."

"If we are the only one in power."

"Sooner or later, you will become complacent and stop striving for progress."

After he finished speaking.

Alexei couldn't help being speechless.

Isn't it good to have only one company dominate the market?

With hundreds of millions of dollars in foreign exchange income every year, it would be impossible for them to hope for a second competitor to emerge.

He shook his head and said:
"You are talking without any hesitation. I wish I could switch places with you and enjoy the benefits of this 'monopoly'."

"Actually, I have a suggestion. Would you like to listen to it?" Li Mu said.

Hearing this, Alexei paused and asked:
"What advice?"

Li Mu said:
“Sell War 2 through our game channels.”

Hear Li Mu's suggestion.

Alexei's eyes widened slightly, and at the same time he was shocked, he suddenly felt that it made some sense.

After all, Xiaguo’s sales channels are indeed wider than theirs.

Moreover, their reputation among the player community is much better than theirs.

Don’t say anything else.

For the price of a game console, they sold it for 50 reeds, while Xia State only sold it for 40 reeds.

In this case, there is not much room for competition at all.

"But if you give us the channel, won't you be at a disadvantage?" Alexei said.

He wanted to get all the benefits after getting the channel.

But I can't think of any benefit that Xia Guo will get from doing this.

It may even cause harm.

After all, the quality of their games is much higher than those developed by Xiaguo.

"It's definitely not completely free. We will take a certain percentage of commission." Li Mu said with a smile.

Of course, this is just an excuse.

After all, that little commission is not worth mentioning at the moment.

His ultimate goal is to bring the gaming industry, which is not easy to develop abroad, into their hands.

And he believes that no foreign game manufacturer can resist this temptation.

After all, it's their player base and reputation, or the quality of their consoles.

These are offers that foreign game manufacturers, which are still in their infancy, cannot refuse.

"If that's the case, then there will be no problem." A glimmer of excitement flashed in Alexei's eyes.

I originally thought that the goal of selling 200 million copies would never be achieved.

Now it seems that it may not be impossible.

"That's right." Li Mu said:

"I heard that you have another group of experts coming to Kyoto?" This sentence brought Alexei back to his senses from his happiness, and he said:

"Yes, Professor Ivan is still leading the team, but this time the lineup is even more luxurious, with many more famous professors from our country."

As he spoke, a hint of helplessness flashed in his eyes.

After all, the top leaders attach more importance to Xia’s space-based projects.

This means that he has to find ways to get close to Li Mu and get as much information as possible.

"So that's how it is. It seems that you attach great importance to this cooperation. I feel much more relieved now." Li Mu pretended to be relieved.

Hearing this, Alexei asked in confusion:

"What are you worried about? Does this have anything to do with you?"

"Hey, maybe it's because I showed up a few times, which made you think I was very important. But in fact, it's not like that at all. After the algorithm was written, I had nothing to do..." Li Mu pretended to complain.

Hear this explanation.

Alexei was a little bit unbelievable. He said:

"Have you completed the development of the operating system for the robot dog?"

How long has it taken?

"It's just a framework. Once it's written, I'll throw it to other people to do. I don't want to waste time on this kind of thing." Li Mu shrugged and said.

Alexei asked in confusion:
"How can this be a waste of time? Didn't you say that mechanical dogs have great potential?"

"That also depends on the hardware conditions. For example, no matter how powerful the engine is, the car cannot run without wheels," Li Mu explained.

Alexei suddenly realized.

That's well said.

Isn’t it because of the lack of hardware that Xia State chose to cooperate with them?

If their industrial base really has the conditions to complete mechanical dogs and space-based engineering.

Then why not just make a fortune quietly yourself? Why bother giving a share to others?

……

I chatted with Alexei until about 2pm.

We talked about games, robotic dogs, and then space-based projects.

Li Mudu gave his insights from the perspective of an observer.

This also made Alexei more certain of a fact.

That is, Li Mu should know a little about these two secrets, but not much.

This is quite normal.

For example, in his country, if the top leaders decide to develop a new secret weapon, they will not let too many people know about it.

Even the researchers involved in the research only know what they are responsible for.

As for what it will be when assembled, no one will know.

……

After parting with Alexei.

Li Mu set off for the Kongkong D bomb hospital.

Arrived at the gate.

His car was stopped by security guards.

They were allowed to pass only after showing their ID.

Go inside.

Before I saw anyone, I heard slogans of "one, two, one".

When I walked around to take a look, I saw an old man leading the researchers from the institute to sweep the snow.

Saw this scene.

He didn't rush to find someone, but instead found a broom and asked Zhao Canjun and Guan Jianmin to help.

With the addition of the three of them.

The speed of snow clearing suddenly increased significantly.

General Zhao was a military man, and he swept very quickly and powerfully. He swept an area clean in just a few "Swish, swish, swish".

Li Mu didn't try that hard.

However, although his movements looked slow, each of them was able to stir up a large area of ​​snow, and his efficiency was also extremely fast.

As for Guan Jianmin.

It’s better not to mention it, it’s just a little faster than the old man.

……

Liang Shoupan was sweeping the snow slowly while looking at the three people who suddenly appeared.

When I saw Guan Jianmin.

He then realized that it was Li Mu who came.

When he saw someone, he was already ready to go up and say hello.

Unexpectedly, Li Mu picked up the broom and started doing it.

So he didn't rush up to talk, but observed quietly.

Among the three.

Li Mu is still easy to recognize.

After all, his picture often appears in newspapers.

“I didn’t expect you to be so strong.” Liang Shoupan looked at the flying snowflakes, slightly surprised.

Logically speaking.

A scientist who is so young and already so full of honors should have spent all his time on research.

It's good as long as you have no health problems.

Not to mention someone like Li Mu.

Just when Liang Shoupan was slightly stunned.

Thanks to everyone's efforts, the snow on the open space was finally cleared away.

The young people who had just entered the research institute put down their brooms and planned to ask Liang Shoupan about the next arrangements.

But just as they were gathering their brooms.

A young man suddenly recognized Li Mu and said:
"Advisor Li?"

The voice just fell.

Everyone present turned their heads subconsciously:

"It's really Consultant Li. This is the first time I see him in person!"

"I didn't expect to meet Consultant Li at the Kongkong D-Bomb Institute!"

"Hello, Consultant Li!"

……

The moment Li Mu's identity was confirmed.

All the young researchers immediately became excited.

After all, there is no Xia citizen who doesn’t know Consultant Li.

in their hearts.

I even regard it as a role model and goal for lifelong learning!
"Hello, everyone. Nice to meet you all." Li Mu responded with a smile.

These are all carefully selected good seedlings.

It will definitely be useful when developing air-to-air D bombs in the future.

Just when he was chatting enthusiastically.

Liang Shoupan suddenly coughed heavily from behind and said:
"Advisor Li, when did you come? Why didn't you tell me? I even asked you to help sweep the snow for half a day."

As he spoke, he walked in front of the people in the station.

The position was right between Li Mu and everyone else.

These people are his last thought. If they are poached by Li Mu again, he will be really angry.

"It's okay, it's a good opportunity to exercise." Li Mu smiled and didn't mind.

After all, he is too busy to teach so many trainee researchers who have just started researching air-to-air D missiles.

It won’t be too late to come and discuss things after people have been taught enough.

Liang Shoupan looked at Li Mu and felt that there was something "unfriendly" in his eyes.

He first asked everyone to disperse, and then said:
"Advisor Li, let's get down to business. Are you really researching active radar-guided medium-range air-to-air D missiles?"

"That's right. Otherwise, it would not be possible to transfer so many people from your place, President Liang." Li Mu said.

Hearing this, Liang Shoupan's eyes widened slightly and said:

"But our country mainly uses semi-active radar guidance and infrared guidance. How did you break through this technology?"

He has been researching in the field of air-to-air D missiles for decades.

But even if I rack my brains.

He couldn't understand how Li Mu skipped semi-active radar guidance and infrared guidance and went directly to study active radar guidance.

If there is a reference, then it is easy to say.

But active radar guidance is still just a concept abroad. What reference does Li Mu use?
"Dean Liang, if we follow the steps, we may be able to quickly catch up with Emperor M and Big Brother, but we shouldn't set this as our goal, right?" Li Mu said with a smile.

He could tell.

Liang Shoupan probably still hasn't fully adapted to Xiaguo's advanced leadership in the fields of computers, precision machining, and electronic technology.

Of course, this doesn't mean that he is not smart.

It’s just that my thoughts haven’t changed for the time being, and I’m still stuck on how to catch up as quickly as possible.

There was no practical reference to tell him what to do next.

"You're right, but first it's better to have it, I don't think there's any problem." Liang Shoupan shook his head and said.

There will definitely be no problem in researching more powerful air-to-air D bombs.

But what Xia Kingdom needs more now is to solve the existing problems.

Li Mu said:
"If it's just ordinary air-to-air D-bombs, do you think it's enough to deal with foreign fighter jets?"

"Take one step at a time. As long as you persist, there will be a day when your hope will come true." Liang Shoupan sighed.

How could he not know.

Even if ordinary air-to-air D bombs are produced, the effect they can have is very limited.

But a person's energy is limited.

His energy had been exhausted on the research of the D bomb, and it was impossible for him to study fighter jets.

But he believed it.

There must be comrades like him who are working hard for the birth of a powerful fighter jet.

One day, their efforts will become pieces of the puzzle for the motherland's prosperity and national rejuvenation.

Li Mu looked at Liang Shoupan's determined expression and said:

"What if I tell you that I can develop an active radar-guided medium-range air-to-air D missile within three years?"

"If you can really do it, why not let me be the dean?" Liang Shoupan waved his hand.

He wasn't joking.

If he can really do it, it will be enough to prove Li Mu's ability.

Then, it would be most appropriate for Li Mu to be the dean of the Kongkong D-dan Academy.

Li Mu smiled and said:

"That's not the case."

"I'm still young, and I don't want to spend my whole life researching air-to-air D-bombs."

"Well, here's a research draft. Would you like to take a look at it first?"

This time he came with a trump card.

Liang Shoupan looked at the documents handed over by Li Mu.

The thickness this time is much thicker than the previous plan.

However, he still didn't think that Li Mu could come up with any feasible plan.

After all, the primary difficulty of the active radar-guided medium-range air-to-air D missile is the radar problem.

"Millimeter wave radar? It seems interesting." Liang Shoupan opened the file and his expression became much more serious.

The title of the document is "Application of Millimeter Wave Radar in Air-to-Air D Missiles".

In the current research on air-to-air D missiles.

There are two kinds of radar, X-band radar and millimeter wave radar.

The former originated in the late 20s and early 30s and was an important frequency band in the early development of radar technology.

It gradually matured in the 50s and was widely used in fields such as D-missile guidance, weather radar and marine radar.

However, it is widely believed in academia that millimeter-wave radar is more suitable for high-performance D-missile guidance systems.

However, whether it is Emperor M or Big Brother, the research on millimeter-wave radar is still mainly concentrated in the laboratory stage.

As for when can it be applied?

Liang Shoupan didn't know this either.

After all, Xia Country has not yet started research on millimeter-wave radar.

He thought for a while and said:

“How do you plan to solve the technical and equipment problems of high-frequency microwave components?”

Millimeter-wave radar needs to operate in a high frequency band of 10 GHz to 300 GHz, which is difficult to achieve with their current technology.

There are no high-frequency microwave components.

It is impossible to reach the operating frequency band of millimeter wave radar.

Then it is nonsense to develop an active radar-guided medium-range air-to-air D missile.
