(For @ Forever Brother Wang's big alliance plus more 3/5)

Liu Yijiu looked at the excited welders in front of him and didn't say anything.

After more than ten minutes of confrontation, Liu Yijiu spoke, "Tomorrow, I'll go in, and you guys will watch outside!" ”

He didn't say this at first, he was actually struggling, or he would have left only five female welders, and he would use this reason to eliminate these male welders. But that would not be at all in line with the development of engine-building technologies in the republic.

The welding work in the pressurized cabin is not only for aero engines, but also for the future pilot training, and even the development of manned space engineering, which requires more advanced research in this area.

Moreover, the atmospheric pressure should reach a higher degree.

So, it's not enough to just have female welders.

At the age of six, he had already judged the female welders to be qualified, just to see their limits. It has already aroused the anger of the masses and is not in line with the future progress of the work.

That's why he said it.

Because tomorrow, will he wear a protective suit into the pressure chamber! Of course, you still have to wear what you breathe.

His current physical fitness is far several times higher than that of ordinary people, that is, the fighter plane flies at a speed of more than Mach three, and his body is able to withstand it, and he can also operate flexibly.

"Director Liu, is it too dangerous for you to do this? It's just a selection of welders, and if something happens to you, how do you get it? "For something like this. Huang Qiaosong and others were very worried, and after the matter was over, they reported the matter to the General Rear and the General Staff.

The reply was that Long Yaohua would rush to Rongcheng overnight and asked them to delay before that.

can stop Liu Yijiu. There are only higher-level authorities.

At the same time, the General Staff ordered Wang Shunyi to rush to Rongcheng to dissuade Liu Yijiu.

If you don't know the danger, there is no problem, even if you wear protective clothing, it's all like that, Liu Yijiu doesn't wear protective clothing to go in, and you still have it?

"There are things. You don't understand. After tomorrow, they won't have anything to say! Liu Yijiu shook his head helplessly, "Now the physical limit of human beings." It seems to be subjected to 8G acceleration, while the fighter is designed to withstand 9G. Have you ever thought that our double-third project has been successfully developed, and the performance of the fighter has been reached. Our pilots. Will it be able to bring out the performance of the fighter? ”

Huang Qiaosong was stunned.

From the very beginning, the 611 Institute has been designing a double-three performance fighter with a flight altitude of 30,000 meters and a flight speed of more than Mach 3.

Ordinary missiles cannot reach Mach 3 speeds, and if there is such a fighter, when encountering a missile, it can escape by relying solely on the performance of the fighter.

In the past, the high-altitude and high-speed interceptors of the double 28 standard in China did not mean that the cruising speed of the fighters could reach Mach 3. It's just an instantaneous acceleration, and it reaches this speed when the afterburner is turned on. Even this type of fighter plane from the United States and the Soviet Union. It's all like that.

The MiG-25 fighter can reach Mach 3 speeds when the afterburner is turned on, but it can only last for 5 minutes.

Even so, Belenko, who fled from Siberia to Japan, set this record, and when Belenko was caught by the United States and Japan, he did not tell the truth when recording a confession. And the MiG-25 fighter obtained by the United States, also because Belenko set a record of flying at a maximum speed of Mach 2.8 for only three minutes, and the MiG-25 with a maximum afterburner of Mach 3.2 for five minutes when he was dodging the missiles that attacked him......

Similarly, because of Mach 3.2, which flew for five minutes, Belenko also suffered from the overload of this flight, and finally escaped to the United States and died after not living for a few years......

"Do you want to build a fighter with a cruise speed of Mach 3?" Liu Yijiu's words made Huang Qiaosong's eyeballs fall off.

With his mouth wide open, he was perfectly capable of stuffing his own fists.

"That's the future! It's hard to even burn at this speed! Liu Yijiu said very calmly.

The missiles of the future will be faster and the satellites will have higher resolution, and a breakthrough in this area will require the development of faster fighters.

After entering the 21st century, the Republic has developed UAVs with a speed of more than Mach 10 and used ramjet engines, but in the end, because the human reaction speed could not keep up, it had to study the supporting human potential development.

Since you want to be advanced, you simply don't hide anything.

"Moreover, there is no accumulation of current processing technology, material base, and even control systems, etc., so how can you do such a thing? Even if we develop it now, will our pilots be able to handle it? Liu Yijiu said with a sigh.

Such a thing, now can only be thought about.

"What we can do is work towards that."

"But this pressurized cabin has nothing to do with pilot training!"

Huang Qiaosong couldn't figure it out at all.

Liu Yijiu didn't explain, and when he was about to rest, Wang Shunyi arrived, and told Liu Yijiu that Long Yaohua would also go to Rongcheng at night.

"I said you too, do you need to make a fuss about such a thing? Isn't it just a period of time in an environment with two atmospheres? By the time Long Yaohua arrived in Rongcheng, it was already past 11 o'clock at night, Liu Yijiu said with a wry smile.

Long Yaohua didn't speak, just stared at Liu Yijiu with a gloomy face.

Liu Yijiu knew what this big guy meant, "Chief, I'm not taking my own risks, I know what I designed myself." Moreover, there is a core project in our base, which is for this purpose. In the absence of gene technology, or gene enhancement technology can not be used maturely, we can only use this way if we want to enhance the body's bearing capacity. When pilots fly fighter planes, especially when flying at ultra-high speeds, the overload capacity of the body is up to 8 times the gravitational acceleration, and the time cannot be long, even so, pilots who often fly at ultra-high speeds cannot have a long life......

"Doesn't it mean that pilots who have studied abroad will roll their eyes and faint when they are subjected to a gravitational acceleration of 7 G?"

"The way it trains is different."

"You mean, this pressurized chamber can train our pilots?" Long Yaohua was obviously a little skeptical.

"That's true. Chief, do you think that in a greater gravity environment, is it much less that people can bear the weight because of the gravitational pull of the earth? The same object, in an environment with twice the atmospheric pressure, will become heavier, so it is very easy to get tired working in the pressurized chamber......"

Liu Yijiu immediately explained.

If you want to do such a thing, you must have the support of Long Yaohua.

"There are no side effects?" Long Yaohua asked something that should not have been asked.

In this era, as long as the republic can achieve its goal, there are things that it knows will have serious side effects, but it still has to stick to it.

Not because of the issue of the rights of the republics that Western countries have been attacking since the collapse of the USSR, but because the country is backward and there is no way to do it.

If you want to develop the economy, you know that the chemical companies invested by the West in the Republic will harm the environment, so you still have to agree.

This is not the government's short-sightedness, but only when it develops and has money can it better guarantee the country's security.

Western countries only blame the Republic after polluting the environment once.

If it does not develop, the government will have no money, and everything will be controlled by others everywhere. Because in the absence of money, either you will have to borrow money from the country that has money, or you can only refrain from developing.

Lending internationally?

All kinds of strings attached, you can trap people to death!

Moreover, it cannot be developed, it is disobedient, it is directly sanctioned, it is not negotiable at all!

Therefore, Liu Yijiu never reminded the old man that the development of chemical industry in China would pollute the environment.

To develop, you have to pay some, the West does not want to see the rise of China, so it blames these things, and most of the enterprise products that pollute the environment in China are exported to developed countries such as Europe and the United States!

"If you change the atmospheric pressure slowly, there is no problem. If it improves a lot all at once, it won't work. Liu Yijiu doesn't know much about this either.

But in their time, the training of pilots, the training of astronauts, was done like this.

In the beginning, there were units that studied gravity generators, using magnetic fields to change the gravitational environment, but the magnetic field would affect the equipment.

In the end, a crazy scientist was inspired by Lao Maozi's "Atmosphere-24" and wanted to fill the space with compressed gas to counteract the weight loss effect, and found that it could effectively enhance people's endurance in a higher atmospheric pressure environment.

Just like the creatures in the deep sea.

At the same time, the physical fitness has also become better, and the only bad thing is that it is very difficult for offspring to reproduce.

In the end, with genetic technology, this can make humans stronger.

It's just that gene technology is still in the experimental stage, and only a few people can use it. As for training in a higher atmospheric pressure environment, this is already relatively common, and even ordinary army soldiers will train in it.

"So, even special forces can train inside? The whole army will do? ”

"Theoretically, yes." Liu Yijiu replied.

His purpose is just to start this research, because in the pressure chamber, you have to feed air from the outside through the pipe connected to the breathing mask, under normal circumstances, the pressure chamber is made of inert gases that are harmless to the human body, but no matter how harmless, after long-term contact, these gases can also enter the human body through the pores, thus causing subtle changes, because inside the pressure chamber, the atmospheric pressure is twice that of the outside.
