The field of aerospace is a comprehensive engineering technology that explores, develops and utilizes space and celestial bodies beyond the earth, also known as space technology.
Since October 1957, the Soviet Union successfully launched the world's first artificial satellite, which marked the entry of mankind into the space era.
The aerospace technology that emerged from this developed immediately afterwards. The breakthrough of this technology allowed mankind to break away from the fetters of the earth's gravity and enter the vast outer space of the universe. At the same time, it also provided military supplies a new field.
In a sense, outer space has become a new battlefield and the best place for countries to demonstrate their national power.
The high-tech content of space technology is also extremely high. It is the integration of many technological achievements, such as jet technology, electronic technology, automation technology, remote sensing technology, materials science, computing science, mathematics, Physics, chemistry, etc.
However, among these high-tech fields, rocket engines are still the core, top priority and unique of aerospace technology.
The development of my country's aerospace industry is as difficult as the development of the two bombs, or even more difficult from a certain perspective.
After all, the two bombs of that year were guided by the Soviet Union.
However, the development of aerospace has been restricted from the beginning by the Batumi Agreement, the Wassenaar Agreement and the Wolf Clause.
The great powers headed by the Bald Eagle openly led other countries to embargo and ban sales on our country. In some international cooperation, China was unable to participate, which further aggravated the difficulty of the development of our country's aerospace technology. .
It can be said that our country's development in these fields has been achieved through overcoming obstacles and relying on the hard work of domestic scientists and engineers.
There is a counter-intuitive common sense, that is, many people think that the furry bear next door has a good relationship with our country.
But this is not actually the case, it is just an illusion derived from history.
The bald eagle is unwilling to sell rocket engines to us, and so is the furry bear. Not only are they unwilling to engage in technical exchanges, but they are also unwilling to sell some finished rocket engines.
SpaceX’s rocket engines were purchased from Mao Xiong, but none were sold to our country.
From this we can see what the Mao Xiong’s attitude is.
As long as there is a rocket engine with strong thrust and reliable quality, domestic space rockets will undergo earth-shaking changes.
Wang Donglai put the rocket engine as his primary goal because of this idea.
Time passed quickly and it was afternoon.
Song Lin came on time and took Wang Donglai to the training center.
The selected pilots have arrived and selection training is about to begin.
After arriving at the place, the selection training has begun.
At this time, there was a pilot testing the electric seat.
I only saw the electric seat, which sometimes rotates 360 degrees clockwise, sometimes counterclockwise, and also swings up and down and back and forth.
The test with such violent movements lasted for about ten minutes. If it were an ordinary person, I would have vomited on the electric seat.
However, when the electric seat stopped, the pilot on the seat just shook his head and stood up, walking towards the crowd with light steps and bright eyes.
Wang Donglai noticed that when the pilot came over, his steps did not stagger, but were in a very standard goose step.
“Turn left!”
At this time, the aerospace trainer shouted softly and directed the person to turn.
The next second, the pilot immediately turned around neatly, 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 an elite among the elites. I am not surprised to have such a performance."
Wang Donglai looked at the people just now Performance, nodded and said.
“I have seen your performance just now, and I can only say that it is barely qualified.”
"There are many selections for astronauts, and the electric seat is just one of them. It is a relatively simple project."
"So, don't feel complacent that you have passed this project. There are many training projects later. , and finally, passed the training once and twice Training doesn’t mean anything. If you want to complete the aerospace mission, you must pass various training projects every time and maintain the best condition.”
At this time, the aerospace trainer’s expression was on his face. He said this to a group of seven pilots very coldly.
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 does not violate the regulations, can I test it?" ?”
Hearing Wang Donglai’s request, Song Lin was stunned.
After reacting, he quickly spoke out to dissuade Wang Dong.
“Academician Wang, these projects are specially designed for the selection of astronauts, and are beyond the endurance of ordinary people. Many people have tested them, and after they came down, they were vomiting and were in a terrible state. "
Song Lin did not refuse directly, but said so tactfully.
If Song Lin hadn't developed a favorable impression of Wang Donglai because of his behavior before he came, he would have rejected the request as soon as he heard it, and would not have said such tactful words at all.
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 confused. Incomparable.
I subconsciously thought that Wang Donglai saw that there were no negative reactions in the pilot test, and mistakenly thought that he could do it, so he wanted to try it.
To be honest, Song Lin can completely understand Wang Donglai's idea.
After all, Wang Donglai is still just a young man in his twenties. Seeing the pilots selected pass this test easily, it is very normal to have the feeling that this is not the case.
With this thought in his mind, Song Lin gave up the idea of letting Wang Donglai give up.
"Academician Wang, it is not against the regulations to let you test, but if you are injured 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 stop the test.”
"This is very important. If Academician Wang doesn't agree, I won't be able to let you test it."
Although Song Lin no longer objected, he also proposed that Wang Donglai should bear the responsibility. When it doesn't stop, raise your hand to indicate stopping the test.
The tone was very firm. If Wang Donglai disagreed, he would not agree to anything.
Wang Donglai also knew that this was for his own safety, so he had no objection or displeasure.
Immediately and seriously nodded in agreement, and said loudly: "Don't worry, Director Song, when I can't bear it anymore, I will raise my hand to signal!"
"Okay!"
Song Lin nodded and walked up immediately.
After just a few brief explanations, aerospace trainer Su Jie came over.
He also held a black blindfold and vomit bag in his hand.
"Academician Wang, you will feel better if you wear a goggle. This is your first time testing this kind of equipment, so you will definitely have some reaction. If you feel that you can't stand it, you must raise your hands to indicate it as soon as possible, and we will The test will be stopped, don’t panic.”
When Su Jie said these words, his tone was calm, as if he was dealing with work.
Wang Donglai didn't care. No matter who looked at him, he seemed to be deliberately looking for trouble.
Obviously I am not a relevant person, but I still insist on trying such a harsh equipment.
It just so happened that I still had the status of an academician, so it was difficult to refuse.
This change also aroused the curiosity of the pilots who came to participate in the selection training.
Su Jie's voice was not deliberately lowered, so everyone also heard the name Wang Donglai.
Academician?
Still so young?
Wang Donglai's identity was immediately guessed. "Okay, but I think I won't be able to use this vomit bag!"
With a confident smile on his face, Wang Donglai held up the vomit bag in his hand and faced it Su Jie and Song Lin said.
After saying that, Wang Donglai took the initiative and walked up.
Soon, everything is ready.
Buzz!
After powering on, the electric seat immediately began to rotate rapidly.
At the beginning, the difficulty was not too great, and the rotation speed obviously slowed down.
But even this speed is already unbearable for ordinary people.
Ordinary people will feel dizzy and unsteady even if they spin quickly on the ground for more than ten times.
At this moment, Wang Donglai was suffering from the dizziness caused by the speed of more than ten circles per second.
No one spoke. The dozen or so people present all focused their attention on Wang Donglai.
A tense atmosphere suddenly filled the air.
Song Lin, Su Jie and other training center staff looked the most nervous, but they were also the most relaxed.
Because as insiders, they know the difficulty of this project very well. If pilots can pass it easily, it is because they have relevant experience. If ordinary people want to pass it easily, the difficulty is probably no easier than buying a lottery ticket.
Especially ordinary people who have not received special training.
However, as time passes by,
Wang Donglai on the electric seat did not raise his hands, and his expression was very relaxed.
"Director, do you want to continue to follow the test process and increase the difficulty?"
At this time, Su Jie was a little unsure, so he asked aloud.
According to Su Jie's previous thoughts, Wang Donglai might not be able to pass even the simplest initial test, and he never thought about the possibility of passing the initial test.
But now it has become a problem.
Song Lin also felt a little embarrassed, but thinking of the confidence and determination in Wang Dong's tone before he came, he gritted his teeth and said: "Make it more difficult, don't be too sudden, and at the same time, you must be careful. Once he raises his hand, he is ready to stop at any time."
With Song Lin's words, Su Jie no longer hesitated.
Turn the knob and the difficulty suddenly increases.
In addition to the speed getting faster and faster, it also started 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 operating.
The world was spinning, and my hands and feet felt weightless.
But this feeling comes and goes quickly.
In just a few breaths, Wang Donglai got rid of this feeling and became accustomed to it.
But when the difficulty was increased, Wang Donglai still felt a little uncomfortable for the first time, but compared to the beginning, it had weakened a lot.
And the speed of adaptation is also much faster.
One minute!
Two minutes!
Three minutes!
When Wang Donglai persisted until the third minute, he still didn’t raise his hand to signal to stop, and his expression was still very calm.
Everyone present was surprised, especially the training center staff such as Song Lin and Su Jie, who were even more shocked.
They are very aware of the difficulty of this test, and the electric seats are still fully powered at this time.
Being able to persist in this state for three minutes means something. The staff at the training center know very well what this ability is.
Moreover, this time is not the limit for Wang Donglai.
Judging from his expression, it is obvious that he can continue to persevere.
Even the pilots watching from the side showed surprise. They had just completed this test and had the best say.
Although they are all experienced pilots and have high resistance to such tests, this does not mean that they complete these test tasks easily.
They are also mortal bodies, and they will still have the reactions they should have, but they need to have a higher adaptability and a stronger tolerance. In addition to strong muscle reactions, they can pass the test.
But Wang Donglai is not like this. It is really unexpected that an ordinary person, without any relevant training, can perform like this.
Five minutes!
Eight minutes!
Ten minutes!
When ten minutes arrived, Song Lin couldn't sit still.
This result is already extremely good, and not all experienced pilots can persist until this point.
For the selection of astronauts, if you can stay on the electric seat for ten minutes, you have reached the qualification line.
So, when the ten minutes were up, Song Lin had the idea of stopping the test.
If you persist for another five minutes, you will already be a qualified astronaut.
However, Song Lin did not think Wang Donglai could persist until that time.
Because every minute on the electric seat is a kind of torture, and as time goes by, this discomfort will become more intense.
But Song Lin also had a bigger worry in his heart, that is, he was worried that Wang Donglai had actually fainted on the electric seat.
If this is the case, if we continue, some unexpected situations are likely to occur.
Song Lin will undoubtedly take responsibility.
For such considerations, it is extremely normal for Song Lin to want to stop testing.
"Su Jie, do you think Academician Wang can still bear it?"
However, Song Lin still asked Su Jie.
Hearing Song Lin's question, Su Jie observed it in detail and then said with certainty: "Director, I think Academician Wang can still persist!"
"No. Thinking that Academician Wang’s physical fitness is so good without any training , I can persevere until this point. If I train a little more, I will definitely be a good candidate for astronauts!"
"It's just a pity that Academician Wang is engaged in academic research after all, and the organization may not let Academician Wang do it! Come be an astronaut!”
Su Jie's tone contained a hint of excitement and a hint of pity.
“Are you sure?”
Song Lin asked again.
Su Jie didn’t think much and said loudly: "Director, I am sure!"
"Academician Wang’s breathing was steady and strong, and the expression on his face was calm and did not reveal anything. His expression was somewhat uncomfortable, and his body posture was obviously very relaxed. From this, I judged that Academician Wang could hold on for a while longer.”
"It's already eleven minutes now, not far from the standard fifteen minutes for astronauts. I think we can continue to observe and give Academician Wang a little more time."
Hearing Su Jie say this , Song Lin nodded, patted Su Jie on the shoulder, and said warmly: "Okay, then I will listen to you and observe again!"
"However, still Pay close attention to the changes in Academician Wang’s expression, and stop immediately if there is any situation!”
“After all, Academician Wang is the youngest academician in our country and a rising star in the field of mathematics in the country. With such a great reputation, if someone gets hurt here, we will really become sinners." (End of Chapter)
