Add 35 updates to the Forever Brother Wang Da League

Liu Yijiu looked at the excited welders in front of him and said nothing.

After confronting each other for more than ten minutes, Liu Yijiu said, "Tomorrow, I'll go in, you guys will watch outside."

He didn't say this at the beginning, but he was actually struggling, or he would leave only five female welders behind, and used this reason to eliminate these male welders. However, that would not be in line with the development of engine manufacturing technology in the Republic at all.

The welding work in the pressurized chamber is not only for aircraft engines, but also for pilot training and even the development of manned space engineering. More advanced research is required in this regard.

Moreover, atmospheric pressure should reach a higher level.

So, it is not enough to just have female welders.

In six hours, he had already determined that these female welders were qualified, but in order to see their limits, they have already aroused group anger and are not in line with the future work progress.

That's why he said this.

Because tomorrow, he will not wear protective clothing and enter the pressure compartment. Of course, he still has to wear something to breathe.

His current physical fitness is far more than that of ordinary people. He is that the fighter planes fly at a speed of more than Mach three, and his body can withstand it and can operate flexibly.

"Director Liu, isn't it too dangerous for you to just select welders? If something happens to you, what will happen?" Huang Qiaosong and others were very worried about such a thing, and after the matter was over, they reported the matter to the General Secretary and the General Secretary.

The reply he received was that Long Yaohua would arrive in Rongcheng overnight and asked them to delay before.

The only one who can stop Liu Yijiu is the superior competent department.

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 will be like that. Liu Yijiu has to go in without protective clothing.

"You don't understand some things. After tomorrow, they will have nothing to say." Liu Yijiu shook his head helplessly. "Now the limit of human body seems to be to withstand the acceleration of g, and the acceleration designed by the fighter is 9g. Have you ever thought that our double three engineering has been successfully developed and the performance of the fighter has reached. Can our pilots play out the performance of the fighter?"

Huang Qiaosong was stunned.

The 6th Institute has been designing dual-three-performance fighter jets since the beginning, with a flight altitude of 30,000 meters and a flight speed of more than Mach 3.

Ordinary missiles have a speed of less than Mach 3. If you have such a fighter, you can escape by simply relying on the performance of the fighter.

The double-28 standard high-altitude high-speed interceptor used in China did not mean that the cruising speed of the fighter reached Mach 3, but only instantaneous acceleration. It reached this speed when driving after-force. Even this type of fighter jet from the United States and the Soviet Union was like this.

The MiG25 fighter can reach Mach 3 when it is powered on, but it can only last for 5 minutes.

Even so, the record set by Berenko, who escaped from Siberia to Japan, did not tell the truth when recording the confession after Berenko was caught by the United States and Japan. The MiG 25 fighter obtained by the United States also created a record of only allowing flights of only three minutes, Mach 25, which was allowed to fly at a maximum of Mach 2, and flew for five minutes for five minutes because of these five minutes. In the end, the MiG 25 engine was completely destroyed. The most valuable thing of this fighter was not obtained by the West.

Similarly, because of Mach 32 that had been flying for five minutes, Berenko also suffered from overloads due to this flight. Finally, after fleeing to the United States, he died without living for a few years.

"You want to use a fighter with a cruise speed of Mach 3," said Liu Yijiu, which made Huang Qiaosong's eyes fall off.

His mouth was wide open, and he could completely stuff his own fist.

"That is, it will be difficult for afterburning to burn at this speed in the future," Liu Yijiu said calmly.

In the future, missiles will be faster and satellite resolution will be higher. To make breakthroughs in this regard, faster fighter jets must be developed.

After entering the 21st century, the Republic developed drones with speeds of more than Mach 0 and used ramjets. However, in the end, because human reaction speed could not keep up, it had to study the supporting human potential development.

Since you want to do advanced things, you will simply stop hiding anything.

"And, there is no accumulation of current processing technology, material foundation, and even control systems. How could we do such a thing even if we develop it now, our pilots can control it," Liu Yijiu said with a sigh.

Now I can only think about such a thing.

"What we can do is work hard in this regard."

"But this pressurized chamber has nothing to do with pilot training."

Huang Qiaosong couldn't understand at all.

Liu Yijiu did not explain. Just when he was about to rest, Wang Shunyi arrived and told Liu Yijiu that Long Yaohua would also arrive in Rongcheng in the evening.

"I said you are too. Is it necessary to make a fuss about this kind of thing? Isn't it just to stay in two atmospheric pressure environments for a while?" When Long Yaohua arrived in Rongcheng, it was already past night. Liu Yijiu said with a wry smile.

Long Yaohua didn't say anything, but stared at Liu Yijiu with a gloomy face.

Liu Yijiu knows what this boss means, "Chief, I'm not taking risks with myself. I know what I designed myself. Moreover, there is a core project in our base for this purpose. Without genetic technology, or gene enhancement technology cannot be used maturely, we can only use this method to enhance the human body's ability to withstand. When pilots are flying fighter jets, especially when flying at super high speed, the overload capacity of the body is the maximum gravity acceleration, and the time cannot be long. Even so, pilots who often fly at super high speeds cannot have a long lifespan."

"It's not that pilots studying abroad will roll their eyes and faint when they receive a gravity acceleration of 7 g."

“The training method is different.”

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

"It's true. Chief, think about it, in an environment with greater gravity, due to the earth's gravity, is the weight that people can bear much smaller than the same object, and will become heavier in an environment with twice the atmospheric pressure, so working in the pressurized chamber is very easy to get tired."

Liu Yijiu explained immediately.

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

"There is no side effects." Long Yaohua asked what he shouldn't have asked.

In this era, as long as the Republic can achieve its goals, some things must still be persisted even if they know that they will have serious side effects.

It is not because of the human rights issue of the republic that Western countries have been attacking after the collapse of the Soviet Union, but because the country is backward and has no choice.

To develop the economy, we know that chemical units invested in the West in the Republic will harm the environment, so we still have to agree.

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

Western countries blame the Republic only after they pollute the environment once.

If the government does not develop, the government will be subject to everything they do without money. Because when there is no money, either lend money to a rich country or it will only fail to develop.

Loan internationally

All kinds of additional conditions can kill people

Moreover, if you can't develop, you will be disobedient and will be punished directly, and there is no negotiation at all

Therefore, Liu Yijiu never reminds the old man that developing chemicals in the country will pollute the environment.

To develop, we have to pay some effort. The West does not want to see China's rise, so we blame these things. Moreover, in China, most of the corporate products are exported to developed countries such as Europe and the United States.

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

But in their era, pilot training and astronaut training were all done in this way.

At the beginning, some units studied gravity generators and used magnetic fields to change the gravity environment, but the magnetic field would affect the equipment.

Finally, a crazy scientist was inspired by the Russian "Atmosphere 24" and wanted to fill the space with compressed gas to offset the weight loss effect. He found that in an environment with higher atmospheric pressure, he found that people can effectively enhance their ability to withstand it.

Just like those creatures in the deep sea.

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

In the end, in conjunction with genetic technology, this will make humans stronger.

However, genetic technology is still in the experimental stage, and only a few people can use it. As for training in higher atmospheric pressure environments, this is already quite common, and even ordinary military soldiers will train in it.

"In this way, even the special forces can train the entire army in it."

"In theory, that's the case." Liu Yijiu replied.

His purpose is just to start research in this area, because when moving in the pressure chamber, air must be input from the outside through a pipe connecting the breathing mask. Generally, the pressure chamber uses inert gases that are harmless to the human body, but no matter how harmless it is, after long-term contact, these gases can also enter the inside of the human body through the pores, causing some minor changes, because inside the pressure chamber, the atmospheric pressure is twice that of the outside.
