The Red Era, the Opening University Speech

Chapter 288 42 Mach, one looks and one is silent
Wang Ya, who was taking off her apron, glanced at him, then quickly looked away and said lightly, "Are you awake?"

"Yeah, he's awake." Li Mu nodded and walked forward.

Wang Ya still didn't look at him, but just pointed to the food on the table that had been reheated several times.

Although his stomach was growling with hunger, Li Mu did not rush to wolf down his food.

Instead, he honestly admitted his mistake and said, "I'm sorry, I shouldn't have gotten up in the middle of the night to work."

He worked day and night in the study, and he could hide it from others but not from Wang Ya.

On the first day he said he would rest after getting through tonight, and on the second day he still said he would rest after getting through tonight.

On the third day, seeing that Wang Ya was angry, he went to bed early, but he secretly got up in the middle of the night and went to the study to continue working.

There's no way, time is too tight.

"Okay, I'm not angry, but you just have to stop doing this. Work is important, and your health is important too. Let's eat quickly." Wang Ya turned around and tidied up his hair which was a little messy from sleeping, and said.

Li Mu nodded quickly and promised: "I will pay attention next time."

He said "definitely not", but he really couldn't guarantee it.

In the future, it is inevitable that there will be information like the UH-60 Black Hawk helicopter engine information this time, which will require him to spend a lot of time to quickly memorize information.

If you don't write it down, you may never have another chance to do it again.

Between the temporary overdraft of his body and the long-term development of scientific research, he will inevitably choose the latter.

Wang Ya obviously knew this as well, and gave Li Mu a helpless look.

……

Had a meal.

Li Mu was full of energy and originally wanted to go to the study to complete the final sorting of materials.

But looking at Wang Ya's eyes, he finally gave up the plan and went back to his room to rest.

Lying in bed, he first responded to some of Ask's messages.

Then he opened the chat page again and looked for information about modified double-base propellants.

When he saw the WIFI name of the row of laboratories in General Electric, he reacted.

A large company like this cannot just research helicopters; its business scope must cover the entire aerospace field.

The result was as he expected. He quickly found the database of General Electric Aviation Group.

It contains almost all kinds of information on jet and turboprop engines for civil, military, business and general aircraft.

Any one of them would be enough for the Aviation Institute to study for a long time.

However, Li Mu’s goal is also very clear - to modify the formula of double-base propellant.

"Found it!" After entering the keyword search, Li Mu quickly locked onto his target, and then relied on his strong memory to memorize all the key data in the formula.

With these, the problem of solid propellants can be quickly solved.

Xiaguo's research in the field of aerospace will also go further.

But it's not over yet.

He continued to browse the database, trying to find some more core technologies.

"Supersonic wind tunnel? That's a good thing." Li Mu's goal was very clear, and it didn't take him long to find a very critical technology.

Whether it is a rocket, an airplane, or a D-bomb, as long as it is an aircraft, a wind tunnel is needed.

It can simulate experimental environments and provide a scientific basis for the design and improvement of aircraft or other entities, and its importance is no less than that of the engine.

"But this cost is a bit outrageous." Li Mu was so angry when he saw the final cost that he almost cursed.

The cost of tens of millions of dollars is not unaffordable, but the price is a bit too high.

He also remembered that in 69, Xia Guo had built the JF8 large wind tunnel at a cost of only 10 yuan.

Using JF8, they also successfully developed the Dongfeng 5 intercontinental D bomb.

Although such a low-cost wind tunnel has many disadvantages.

But with a cost of 10, even if he blew it up, Li Mu would still praise him: "It was a loud bang."

Moreover, the wind tunnel technology of the Xia Kingdom in later generations was at least 20 to 30 years ahead of the international level.

There was really no need for him to learn foreign technology, not to mention that the information in General Electric Aviation Group was not very detailed.

"I'll try to trick Ask into coming to Xia Country later." Li Mu closed the information page on wind tunnel technology and thought to himself.

Next, he planned to look at other technical information.

At this moment, he suddenly felt a warm body pressing against his side.

The fragrance lingers on the nose.

"Go to sleep!" Li Mu decisively closed the chat page.

……

The next day, early.

Li Mu got up yawning.

After washing up and exercising, he sorted out the information on the T700/CT7 turboshaft engine while continuing to browse the database of General Electric Aviation Group in his mind.

Despite what he said yesterday, he still wanted to learn more about wind tunnel technology.

The technology of the Xia Kingdom was leading, but it was also in later times.

Now they are still in the backward stage.

Especially before the successful development of JF8, Xia Guo's research on wind tunnels was full of difficulties.

In 63, the JF-4a wind tunnel that was to be built the next year had a serious accident that resulted in the entire building being blown up.

The reason is insufficient technology and cost.

“Maybe I can try computer simulation. Although it can’t replace the actual wind tunnel, it can at least greatly reduce the risk.” Li Mu thought secretly in his heart.

It is impossible to use a computer to simulate all the actual details of air flow, parameter settings, etc., not to mention now, and it will never be possible in the future.

But this does not hinder its cost-saving practicality.

"Let's report it later and set up a project." Li Mu didn't think too long before he decided on a basic research plan.

With the current maximum computing power of 02w times per second of the Type 1000 computer, it is obviously unrealistic to create a simulated wind tunnel.

But the second-generation supercomputer has this opportunity.

At this point in the experiment, Li Mu can roughly estimate the final computing power - it will not be less than 500 billion times per second.

A 50-fold increase is enough to shock the world and make other countries look up to Xia Country for the next to years!
And this number is not the limit.

As long as we add a few more servers and integrate them into the supercomputing network, it is not impossible to reach 550 billion times per second.

But Li Mu felt that it was unnecessary. Not only would the size increase a lot, but the excessive computing power would also affect the overall performance.

Taking heat dissipation as an example, at 500 billion times per second, if the computing power is fully utilized, there will be no major problems in running for a long time.

But once it reaches 550 billion times per second, the running time will be greatly reduced.

Similarly, the performance of other parts will also be affected.

"The second-generation supercomputer is almost able to produce the first-generation version of the simulated wind tunnel. The third-generation supercomputer should be able to fully perfect it. It should be sufficient before we study supersonic speeds." Li Mu made the final judgment.

The gap in wind tunnel level between the Xia Kingdom and other countries in the world in later generations was widened in the supersonic stage, and the Xia Kingdom was far ahead.

The speed of Mach 42 made all countries silent.

……

Li Mu spent a whole morning organizing the information and also looked at the technical information about the wind tunnel.

When it was almost noon, he asked Guan Jianmin to come over and take a bus to the Chinese Academy of Sciences.

Seeing the two plans, Guo Mo was stunned and asked, "Why two?"

"The other one is my research plan for modified double-base propellants, that is, solid fuel propellants. Please take it to the Institute of Aeronautics and ask the experts and professors there to give me some advice." Li Mu smiled. Guo Mo was shocked after hearing this and said, "Solid fuel propellants, you are also researching this?"

He didn't believe that Li Mu took out a plan and really took it to the Aviation Academy for correction.

There might be a complete solution for solid fuel propellant in here.

"It's just my personal interest. I originally wanted to go there in person, but after a few days, I wanted to take a break, so..." Li Mu felt a little embarrassed.

Guo Mo waved his hand and said, "What's the big deal? You just want to start research and development right away, but we don't agree."

"You should take a good rest for two days. There's no need to rush the research and development."

"I will pass these two plans to Dean Tang, don't worry."

"Then I'll leave it to you, President Guo." Li Mu said with a smile.

Of course, he didn't really want to rest, he just wanted to remember more information while Ask was still in Boston.

Compared with this, temporarily sacrificing one or two days of research progress is nothing.

After saying that, he said goodbye to Guo Mo and left.

……

Having said that, Li Mu still came to the Semiconductor Research Institute in the afternoon.

Wu Youxiang and Wang Shoujue wanted to persuade him to go back and rest, but after he promised to only stay in the office, they let him stay.

Enter the office.

Li Mu placed the briefcase on the table and immediately opened the chat page.

Because he was busy organizing the information, he didn't have time to check it until now.

Above is the message Ask sent early this morning: "Lee, look, UH-60 Black Hawk helicopter, picture jpg."

In the picture, Ask is standing side by side with a girl in front of a helicopter, giving him a thumbs up.

Li Mu's gaze lingered on the girl's face for a moment. Who else could it be other than a rich young woman?

"Sure enough, the only thing that's toughest about your body is your mouth." Li Mu smiled slightly, but didn't rush to expose him, and replied: "Handsome! Thumbs up jpg."

"Yeah, I even went on it for a ride, Li, when you come over next time, I'll take you on a ride too, and we can have fun together in Boston!" Ask replied quickly.

Li Mu smiled and said:

"You, take me?"

"Why do I not believe it so much?"

"Can you see all of Boston in just a few days?"

He had to find a way to keep Ask for a few more days.

Of course, this is also for the further development of the relationship between Ask and the little rich woman.

"Li, you may not believe it, but after my research was successful, two investment companies wanted to invest in my laboratory yesterday. I have plenty of time now and can play for a week." Ask replied happily.

Hearing this, Li Mu's eyes lit up slightly.

He was not as naive as Ask, and he could guess that this was most likely the work of the wealthy woman.

But this is not important.

What matters is that he has one more week.

With the chat page's maximum download speed of 8.64G per day, he downloaded as much as 60G of data.

Even though the data of those engines starts at hundreds of gigabytes, it doesn’t mean there are no smaller ones.

Thinking of this, Li Mu quickly replied: "Then I wish you a happy time. I look forward to meeting you then."

"Me too," Ask said.

……

End the chat quickly.

Li Mu opened the WIFI list and turned to the WIFI array belonging to General Electric.

But after hesitating for a while, he continued to flip through the pages.

Suddenly, a WIFI name caught his attention - Cummins Boston Branch Database.

He remembered the name. The company was founded in 1919 and its research scope was quite broad, involving research on diesel and natural gas engines.

Although it is just a branch, it might have some technology that I can use.

Thinking of this, Li Mu immediately clicked to connect to WIFI.

Then type and search "engine" in the other party's database.

The page jumps and a large amount of information is refreshed quickly.

He almost immediately saw the name of a technology - high-horsepower diesel engine.

Although Xiaguo's current industrial level is capable of producing J-brand trucks, its performance in many aspects cannot be compared with that of other countries in the world.

Take the load capacity for example. The maximum load capacity of the J brand is only 3 tons, while the M Emperor of the same period can reach 11.2 tons. The difference is quite big.

"If we can develop a high-horsepower diesel engine, it will also make up for our country's shortcomings in transportation." Li Mu thought secretly in his heart.

Of course, it can also make the battle with India in the near future easier.

As long as the logistical support keeps up, it will be no problem to defeat the Indians.

It would be best if we could fight like the Xiaoyue in the southeast, so that they won't jump around and provoke us in the future.

"This seems good." After Li Mu made a decision, he quickly searched for keywords in the information.

Then I found a military truck of Emperor M——M915.
这款货车的发动机采用的是的是一台康明斯NTC400 6缸柴油发动机，功率为400马力，转速2100转/分，有12个前进档和2个倒档。

Maximum load, 34 tons.

Although it still needs an M872 semi-trailer to accompany the operation, the load capacity is really amazing.

What’s more important is that his data is only 50G in size!

After reading it, Li Mu understood the reason: "After all, it is a branch company, the information cannot be so detailed."

"But this is enough. It will just take a little longer at most."

For the first time, he felt that the lack of detailed information was a good thing.

There is really no chance to download all the hundreds of GB of data.

……

After clicking download, Li Mu closed the chat page.

I looked at the time and realized it was already 5pm.

He stood up and stretched.

Then he set off for the dining hall.

Although he can't go to the laboratory now, it doesn't stop him from having an "accidental encounter".

……

Come to the dining hall.

After finishing his meal, Li Mu sat down at the entrance of the cafeteria, slowly looking through the information about the wind tunnel on the chat page while waiting for people from various research and development teams to come over.

The first to come in was Professor Bai, the leader of the storage system development team.

He had originally planned to come here to deal with the two and then go back, but he didn't expect to see Li Mu as soon as he entered the door. He asked in confusion: "Advisor Li, didn't you ask for leave? Why are you here?"

"Aren't you worried about the research? Come over to eat and take a look." Li Mu said with a smile.

He eats too much, so he basically eats all three meals in the cafeteria, so this reason is reasonable.
