"I............ Cao! ”

High in the sky, there is a mood particle that spreads among the clouds.

There was a silver fighter plane, heading towards the clouds, rushing out of the clouds, and with the drive of the engine, it also left a long tail in the air.

This fighter is a little different from a normal fighter in that it is a two-seat fighter, which means that there are two seats inside, which can seat two pilots.

With these two seats, one seat is mainly responsible for piloting and the other seat is mainly responsible for attacking, so that the pilot can not only control the flight of the aircraft without distraction, but also ensure the accuracy of the attack process.

For example, when it comes to airplane dogfighting, the advantages of a two-seater fighter are obviously beyond doubt.

And this fighter soaring in the air is the J-20S, the world's first two-seat fifth-generation stealth fighter, which can be called the 5.5th generation or even the 5.5th generation.

To some extent, this two-seat design may also be prepared for the 6th generation fighter, after all, the 6th generation fighter has not really been born, although there are already some standards that can be referred to in the world, but the specific standards are not really available before the 6th generation fighter, no one can say.

However, for now, the current J-20S is the 5th generation fighter with the strongest comprehensive advantages.

At this time, the two pilots sitting in the cabin of this fighter plane, the pilot in charge of piloting was piloting the fighter with peace of mind, and the pilot sitting in the passenger seat seemed to have come to experience it - in fact, he was here to experience it.

Because this pilot is Li Mu.

According to what he said to Academician Cheng Guodong, he has to experience what it feels like to ride the J-20S.

The only regret is that because he is not a professionally trained pilot, he can't experience any advanced fighter skills such as falling leaves, nor can he experience the push back feeling of slamming the throttle.

All in all, there is nothing else to do other than being able to observe the sky around you through the fully transparent canopy and then experience supersonic flight once in a while, as if you were flying in a civil aviation.

Of course, no matter what, just talking about his perspective is cool enough.

The voice of the ground base came from the communicator: "Is it cool? ”

"Cool!"

Li Mu laughed back.

Gan, what man doesn't want to fly in a fighter jet?

And now he has realized his dream.

In this way, after flying in the sky for a while, his first fighter jet ride in his life came to an end.

With the pilots' skillful control, they eventually landed on the base runway.

The ground crew stepped forward one after another, and at the same time, a group of people who looked like leaders came over, including two generals who carried Venus on their shoulders.

With the opening of the cockpit canopy, Li Mu also got off the plane with the help of several ground crews.

"Did it have fun?" Among those leaders, Academician Cheng Guodong was also among them, and after seeing Li Mu, he stepped forward and asked with a smile.

"It's enjoyable." Li Mu nodded, gave a thumbs up, and at the same time didn't forget to give a thumbs up to the pilot who took him to fly just now, and thanked him.

The pilot's flying skills were so good that even a man who had never flown in a fighter plane felt almost completely uncomfortable.

"Okay, it's over, let's introduce you first, this is Chief Chen Zhong, and the J-20S you are sitting on today is also approved by Chief Chen."

Next, Academician Cheng introduced Li Mu to the leaders next to him.

"Hello, thank you for your approval." Li Mu smiled and stretched out his hand to shake the general of the three gold stars.

And this General Chen Zhong, who is also in his 60s this year, looks as if he has a sense of self-esteem without anger, and while shaking hands with Li Mu, he also smiled heartily: "Mr. Li is polite, after all, this time is also our Air Force's request, we have been looking forward to the H-20 for too long, and now I hope that Mr. Li can lead us to break through this last hurdle." ”

"I'll do my best."

Li Mu nodded solemnly.

Then, Chen Guodong introduced several other important figures to Li Mu, in addition to the leaders of the military region, and then several of the main researchers who were also their main researchers of the Hunting Heaven Program, all from the four research institutes of 621, 622, 623, and 624.

After the introduction of the personnel, they officially entered the topic.

The base where they are located is Huaguo's research base in the field of air force science and technology, and the ultimate purpose of all research projects here is to devote themselves to the use of the air force.

In addition to materials research, various military aerospace technologies will also be verified here.

For example, the wind tunnel technology, which is necessary for aviation research, has built what can be called the largest wind tunnel in China, which is completely comparable to the JF-22 wind tunnel in Shangjing.

Of course, the technology here is basically not much different from the technology on the JF-22 side.

As for why the experiment was not carried out directly on the JF-22's side, the reason is simple, the JF-22 is open and can be used for both military and civilian research.

And the most important task of this wind tunnel on their side is to help them study the H-20, the most secret strategic bomber.

“这风洞在性能上和JF-22一般无二，最大风速约为30马赫，而在最低风速上我们比JF-22还要拓宽了下限，达到了2马赫的程度。”

Under the leadership of Cheng Guodong and them, Li Mu saw the wind tunnel located under this base, named ST-2 Wind Tunnel.

Li Mu nodded and sighed with emotion: "What a big guy." ”

Cheng Guodong smiled: "After all, we still have to use it to experiment with aerospace technology, and the highest Mach 30 is designed for the research institute of aerospace technology." ”

Li Mu bowed, and then he shifted his gaze to a big guy at the mouth of the wind cave.

It's an aero engine, and it's a model you've never seen before.

Anyway, it's definitely not the WS-15 engine used on the J-20, because this is obviously a lot bigger - he just sat on the J-20S, and he can see all the data with the naked eye.

"This is WS-22?"

"Yes." Cheng Guodong nodded, and then turned his head to look at the big guy.

The WS-22 is the engine they designed specifically for the H-20.

The outside world has been discussing what engine the 20 will use, some speculate that it is the WS-15, some say it is the WS-18, and even say that the WS-20 will be used.

Obviously, they weren't happy with these past models, and the WS-22 was born.

"In terms of aerodynamic layout, this WS-22 is already a perfect match for the H-20, but the problem now, I also told you before, under the long-term flight, the WS-22's turbine fan blades will have serious deformation problems, and all performance has declined......

Fan blades break in the air......

Just thinking about it can be a disaster.

Especially for military technology.

Military technology can not be advanced in performance, but it must be safe and reliable.

So the AK-47 became a rifle that proliferated around the world.

所以顶尖的芯片制程都已经要3nm了，军工芯片还普遍采用28nm、45nm甚至是90nm以上的制程。

"Therefore, we now need to develop a completely new fan blade material to replace our current fan blade material."

Cheng Guodong helplessly spread his hands: "But obviously, this kind of material is not so easy to come out, and it is difficult to talk about it...... To be honest, if room temperature superconductors had not been studied, I would have thought that room temperature superconductors would be more difficult to study, but now, I think this fan blade material is more difficult to study. ”

Li Mu shook his head with a smile, and then said, "I know." ”

"How? Any thoughts? Cheng Guodong immediately asked expectantly, of course, the others around him were also the same.

This fan blade material is the final step of the WS-22 engine.

How can you not make them look forward to it?

Looking at their appearance, Li Mu suddenly couldn't cry or laugh, and spread his hands and said, "Is it possible that I can still imagine a super fan blade material out of thin air?" I don't have an idea, let me research first. ”

The people next to him who stood out and could be called big bulls were all stunned.

Indeed, how could it be that as soon as the problem was said, Li Mu would be able to come up with a way?

If the aero engine is the crown jewel of the industry, then the turbine fan blade material can be called the crown jewel of the material industry.

Why is this fan blade material so difficult to make?

It is because this material has to withstand the scorching environment of thousands of degrees Celsius all the time, it can be said that the environment that this material needs to adapt to is the worst of all materials in the world.

For example, the WS-15 engine used in the J-20 has reached a vortex temperature of 1700 degrees Celsius or even higher.

For an engine, every 100 degrees increase in pre-vortex temperature can increase thrust by 15%, so the higher the pre-vortex temperature, the better.

In the end, this important responsibility still falls on the fan blade material.

“我们现在采用的是WS-15上面用的材料，FGH4098-15。”

"Here's all the information about this material."

Entering the materials laboratory, Cheng Guodong handed a stack of paper materials to Li Mu.

Li Mu took it, and then began to look at it from the beginning.

FGH4098-15 is a nickel-based precipitation hardening powder metallurgy superalloy, which is very strong in thermal strength.

In the past, the formula and manufacturing process of this material must have been absolutely secret, but now, Li Mu was able to see this secret.

While looking at the various materials of the materials, Li Mu also analyzed the materials in his mind.

Although he now has a number of simulations of the real cosmic environment, according to the tasks promulgated by the system, he needs to combine theory to study materials, and if he uses the real cosmic environment simulation, it may affect the final reward very much, so he intends to study this material completely by his own practice.

Anyway, he doesn't have to spend money, and the entire consumption is paid for by the Air Force.

And since he wants to combine theories, he will naturally not forget the "Principles of Electronic Behavior of Materials".

And that's where his research began.

当然，他倒也不是接下来就要直接住这里了，在这里待上几天，他就可以返回科研院，在科研院内自行研究，只需要确保保密性就行，至少不能让别人知道他研究的是轰20的扇叶材料。

In terms of confidentiality, he doesn't have to worry about it, there will be someone in charge of this thing.

So, a few days later, he returned to Shanghai and returned to the scientific research institute.

Coincidentally, Biwaidi and Ningde also agreed to the agreement they had negotiated and sent someone to sign the patent licensing agreement with them.

在权利上，彭祖公司还要求了一点，就是针对购买电池的第三方，需要他们判定资格，也就是说他们拥有了技术制裁的能力，凡是想要购买他们电池的第三方，除了要在获得了专利授权的这些公司这里购买之外，还需要得到他们的同意。

In this way, they will be able to directly shape their position in the scientific and technological world.

At least, a big battery company like Apple, even if it doesn't please them, basically doesn't want to offend them.

As for the distribution of profits, in addition to the 40 percent profit share, these authorized companies also have a fixed licensing fee of 50 million yuan per year.

Setting this fee is also setting a threshold, otherwise, any small company will come to them for authorization, and it will only affect them at that time.

But in any case, with the news coming out, many battery companies have called, also hoping to get patent authorization.

For a time, the limelight of lithium-sulfur batteries was once again blowing across the country.

But for foreign countries, it is completely heavy.

In the face of the attack of lithium-sulfur batteries, they all feel a kind of pressure.

They seem to have seen that the global battery market will be completely controlled by this company!
