When I am reborn, I just want to be a top student

The aerospace field is a comprehensive engineering technology for exploring, developing and utilizing space and celestial bodies outside the earth, also known as space technology.

Since the Soviet Union successfully launched the world's first artificial satellite in October 1957, it has marked the beginning of the space age for mankind.

The aerospace technology that emerged from this immediately developed afterwards. This technological breakthrough enabled humans to break free from the shackles of the earth's gravity and enter the vast outer space. At the same time, it also provided a new field for the military.

In a sense, outer space has become a new battlefield and the best place for countries to demonstrate their national strength.

The high-tech content of space technology is also extremely high. It is an integration of many scientific and technological achievements, such as jet technology, electronic technology, automation technology, remote sensing technology, material science, computing science, mathematics, physics, chemistry, etc.

However, among these high-tech fields, rocket engines are still the core of aerospace technology, the most important and unique.

The development of my country's aerospace industry is just as difficult as the development of the two bombs, and in some ways it is even more difficult.

After all, the two bombs were once guided by the Soviet Union.

However, the development of aerospace has been restricted by the Batumi Agreement, the Wassenaar Arrangement and the Wolf Provisions from the very beginning.

The great powers led by the Bald Eagle openly led other countries to impose embargoes and sales bans on my country. China was unable to participate in some international cooperation, which further increased the difficulty of developing my country's aerospace technology.

It can be said that my country's development in these fields has been achieved through overcoming difficulties and relying on the hard work of domestic scientists and engineers.

There is a counterintuitive common sense that many people think that the relationship between our country and the neighboring bear is very good.

But in reality this is not the case. It is just an illusion rooted in history.

The bald eagle is unwilling to sell rocket engines to us, and the same is true for the Russian bear. Not only is it unwilling to engage in technical exchanges, it is also unwilling to sell some finished rocket engines.

SpaceX's rocket engines were purchased from Russia, but not a single one was sold to my country.

From this we can see what the attitude of the Russian bear is.

As long as there is a rocket engine with strong thrust and reliable quality, domestic space rockets will undergo earth-shaking changes.

It was with this idea in mind that Wang Donglai put his primary focus on rocket engines.

Time passed quickly and it was already afternoon.

Song Lin arrived on time and took Wang Donglai to the training center.

The selected pilots have arrived and are about to begin selection training.

After arriving at the place, the selection training has already begun.

At this moment, there was a pilot testing the electric seat.

All I saw was the electric seat, which sometimes rotated 360 degrees clockwise, sometimes rotated counterclockwise, and also swung up and down, front and back.

The test lasted about ten minutes with such intense movements. If it were an ordinary person, he would have vomited on the electric seat.

However, when the electric seat stopped, the pilot in the seat just shook his head and stood up, walking towards the crowd with relaxed steps and bright eyes.

Wang Donglai noticed that when the pilot walked over, he did not stagger, but instead marched in a very standard step.

"To the left!"

At this time, the aerospace instructor shouted softly, directing the man to turn.

The next second, the pilot made a clean and neat turn, full of capable momentum.

"Academician Wang, how do you feel?"

Song Lin stood in front of Wang Donglai and asked.

“I think everyone who can come here to participate in the selection is the elite among the elites. I am not surprised to see such performance.”

Wang Donglai looked at the performance just now, nodded and said.

"I've seen your performance just now, and I can only say that it's barely acceptable."

"There are many selections for astronauts, and the electric seat is just one of them. It is a relatively simple project."

"So, don't be complacent just because you passed this project. There are still many training projects to come. Finally, passing the training once or twice doesn't mean anything. If you want to complete the space mission, you must pass various training projects every time and maintain the best condition."

At this time, the aerospace instructor said this to the group of seven pilots with a very serious expression.

Wang Donglai, who was outside, couldn't help but feel moved after hearing these words. He turned his head and said to Song Lin: "Director Song, if it doesn't violate the rules, can I take a test?"

When Song Lin heard Wang Donglai's request, he was stunned.

After he realized what was happening, he quickly spoke up to dissuade Wang Dong.

"Academician Wang, these tests are specially designed for the selection of astronauts. They are beyond the endurance of ordinary people. Many people have taken the test before, and after coming down, they vomited and looked miserable."

Song Lin did not refuse directly, but said so in a very tactful way.

If Song Lin had not developed a slight liking for Wang Donglai because of his previous behavior, he would have probably refused the request the moment he heard it, and would not have said such tactful words.

However, Wang Donglai did not give up.

Instead, he looked at Song Lin very seriously and said, "Director Song, if it doesn't violate the rules, I want to give it a try."

Song Lin heard the firmness in Wang Donglai's words and was extremely confused.

Subconsciously, I thought that Wang Donglai saw that there were no negative reactions in the pilot test, so I mistakenly thought that I could do it too, so I wanted to give it a try.

To be honest, Song Lin could fully understand Wang Donglai's idea.

After all, Wang Donglai is still just a young man in his twenties. It is normal for him to feel that it is nothing special when he sees the selected pilots passing this level easily.

Thinking this in his mind, Song Lin gave up the idea of ​​asking Wang Donglai to give up.

"Academician Wang, it's not against the rules to let you take the test, but if you get hurt during the test, it will be a loss to the country. So if you can't bear it during the test later, you must raise your hand to signal to stop the test."

"This is very important. If Academician Wang doesn't agree, I can't let you take the test."

Although Song Lin no longer objected, he still suggested that Wang Donglai raise his hand to indicate to stop the test when he could not bear it anymore.

His tone was firm. If Wang Donglai disagreed, he would never agree to anything.

Wang Donglai also knew that this was for his own safety, so he didn't have any objection or displeasure.

He immediately nodded seriously to show his agreement and said, "Don't worry, Director Song. I will raise my hand to signal when I can't bear it anymore!"

"Row!"

Song Lin nodded and walked up immediately.

After just a few simple instructions, aerospace trainer Su Jie came over.

He was also holding a black eye mask and a vomit bag in his hands.

"Academician Wang, you will feel better if you wear an eye mask. This is your first time testing this kind of equipment, so you will definitely have some reactions. If you feel you can't stand it, you must raise your hand immediately and we will stop the test. Don't panic or rush."

When Su Jie said these words, his tone was very calm, and there was a feeling that he was just dealing with his job.

Wang Donglai didn't care. To anyone, he would think he was deliberately looking for trouble.

Although he is not an expert in this field, he still insists on trying out such demanding equipment.

But I am also an academician, so it is difficult to refuse.

These changes also aroused the curiosity of the pilots who came to participate in the selection training.

Su Jie did not deliberately lower his voice, so everyone heard the way he addressed Wang Donglai.

academician?

Still so young?
Wang Donglai's identity was immediately guessed. "Okay, but I don't think I'll need this vomit bag!"

Wang Donglai had a confident smile on his face, holding the vomit bag in his hand, and spoke to Su Jie and Song Lin.

After saying that, Wang Donglai took the initiative to walk up.

Soon, everything will be ready.

hum!
After power was turned on, the electric seat began to rotate rapidly.

At the beginning, the difficulty was not that great, and the rotation speed was obviously reduced.

But even at this speed, it is already very difficult for ordinary people to bear.

Ordinary people would feel dizzy and walk unsteadily even if they rotate themselves ten or so times quickly on the ground.

At this moment, Wang Donglai was suffering from the dizziness caused by the speed of more than ten circles per second.

No one spoke, and the dozen or so people present all turned their eyes to Wang Donglai.

A tense atmosphere suddenly filled the air.

Song Lin, Su Jie and other staff members of the training center looked the most nervous, but also the most relaxed.

As insiders, they know too well the difficulty of this project. Pilots can pass it easily because they have relevant experience. For ordinary people, the difficulty of passing it easily is probably no easier than buying a lottery ticket.

Especially ordinary people have not received special training.

However, as time goes by.

Wang Donglai, who was sitting on the electric chair, did not raise his hand and looked very relaxed.

"Director, do you want to continue to increase the difficulty according to the test process?"

At this time, Su Jie was a little unsure, so he asked.

According to Su Jie's previous thoughts, Wang Donglai might not even be able to pass the simplest test at the beginning, and he didn't even think about the possibility of passing the beginning.

But now it has become a problem.

Song Lin also felt a little embarrassed, but thinking of the confidence and determination revealed in Wang Donglai's tone before, he gritted his teeth and said: "Manman, increase the difficulty, don't be too sudden, and also be well observed. Once the hand is raised, be prepared to stop at any time."

With Song Lin's words, Su Jie no longer hesitated.

Turn the knob and the difficulty suddenly increases.

Not only did the speed increase, but it also began to vibrate.

The moment the difficulty increased, Wang Donglai noticed the change.

To be honest, Wang Donglai did feel some discomfort when the electric seat first started working.

The world was spinning, and my hands and feet felt weightless.

But this feeling comes and goes quickly.

In just a breath, Wang Donglai got rid of this feeling and became adapted to it.

However, when the difficulty was increased, Wang Donglai still felt a little uncomfortable at the first moment, but compared to the beginning, it had been weakened a lot.

And the speed of adaptation is also much faster.

One minute!

Two minutes!
three minutes!
When Wang Donglai persisted to the third minute, he did not raise his hand to signal to stop, and his expression was still very calm.

Everyone present was surprised, especially Song Lin, Su Jie and other staff members of the training center, who were extremely shocked.

They knew all too well how difficult this test was, and the electric seats were at full power at this point.

Being able to sustain this state for three minutes, what does this mean? The staff at the training center know exactly what this ability is.

Moreover, this time is not Wang Donglai's limit.

Judging from his expression, he can obviously hold on.

Even the pilots who were watching from the side were surprised. They had just finished the test and were the most qualified to speak.

Although they are all experienced pilots and have a high resistance to such tests, it does not mean that it is easy for them to complete these test tasks.

They are also mortals and will have the necessary reactions, but their adaptability and tolerance need to be higher, plus their muscle reactions are stronger, so they can pass the test.

But Wang Donglai is not like that. It is really unexpected that an ordinary person, who has not received any relevant training, can perform like this.

five minutes!
Eight minutes!
ten minutes!
When ten minutes passed, Song Lin couldn't sit still anymore.

This result is already extremely good. Even not all experienced pilots can persist until this time.

For the selection of astronauts, being able to stay in an electric chair for ten minutes is considered qualified.

So, when ten minutes passed, Song Lin had the idea of ​​stopping the test.

If you can hold on for another five minutes, you will meet the standards of a qualified astronaut.

However, Song Lin did not think that Wang Donglai could hold on until that time.

Because every minute on the electric chair is a torture, and the discomfort will become more intense as time goes by.

But Song Lin had a bigger worry in his mind, that is, he was worried that Wang Donglai had actually fainted in the electric chair.

If this is really the case, if we continue, there is a high probability that some unexpected situations will occur.

There is no doubt that Song Lin must take responsibility.

For this reason, it is extremely normal for Song Lin to want to stop the test.

"Su Jie, do you think Academician Wang can still bear it?"

However, Song Lin still asked Su Jie.

After hearing Song Lin's question, Su Jie observed it carefully and said with certainty: "Director, I think Academician Wang should be able to hold on!"

"I didn't expect Academician Wang to have such good physical fitness. He has been able to hold on until now without any training. If he trains a little more, he will definitely be a good candidate for an astronaut!"

"It's a pity that Academician Wang is engaged in academic research after all, and the organization probably won't let Academician Wang serve as an astronaut!"

Su Jie's tone contained a hint of excitement and a hint of regret.

"you sure?"

Song Lin asked again.

Su Jie didn't think much about it, and said, "Director, I'm sure!"

"Academician Wang's breathing was steady and powerful, and his expression was calm, not showing much discomfort. His body posture clearly showed that he was very relaxed. From this, I judged that Academician Wang could hold on for a while longer."

"It's already eleven minutes, which is not far from the standard fifteen minutes for astronauts. I think we should observe it for a while longer and give Academician Wang a little more time."

Hearing Su Jie say this, Song Lin nodded, patted Su Jie on the shoulder, and said in a gentle voice: "Okay, then I'll listen to you and observe it for a while!"

"However, we still need to keep a close eye on Academician Wang's expression. If anything happens, stop immediately!"

"After all, Academician Wang is the youngest academician in our country and a rising star in the field of mathematics in our country. He has a great reputation internationally. If he gets hurt here, we will really become sinners." (End of this chapter)
