Long-distance running, swimming, gymnastics, spiral ladder climbing, cycling.

The physical training, which lasted for a whole month, made the experts and scholars who were originally powerless.

He has a healthier and stronger body.

"Old Xue, your physical fitness has improved very quickly recently!"

Xu Ying wiped her body with a dry towel and wore only a pair of swimming trunks.

They had just finished their swimming training.

While exercising their whole body muscle groups, they also work on their lung capacity.

"Without your stake, it took me a lot of time to swim optically."

Xue Feng said angrily.

Xu Ying grew up on a boat since she was a child, and when she was young, she had a fight with water and white stripes in the waves.

Xue Feng's home was in the northwest when he was a child, let alone learning to swim.

There wasn't even a pond near the house.

The draft depends on digging reservoirs.

So before that, it took him several classes just to learn to hold his breath.

Although Xu Ying has not swam for a long time after working all these years, after all, the foundation of the past is still there.

If you are a little familiar, you will be able to swim flowers in the water.

"That's right, your current level is at least a district-level swimming team when I was a child."

Xu Ying continued to tease.

After Xue Feng dried his body, he did not go directly, but sat on the bench on the sidelines and looked at the water:

"Do you think we can really become astronauts?"

"We're still far from the requirements of astronauts, right?"

In a month's time, most people's fitness levels are at best back to when they were younger.

There is still a big gap between the astronauts before this.

The vast majority of people are aware of this.

It's just that the daily schedule is full, even if they realize it.

I don't have that much energy to think about whether I can become an astronaut.

The base is staffed by professional physicians and physical trainers.

After the end of the day's heavy training tasks.

They will be given muscle relaxation and relief.

to prevent high-intensity physical training from destroying their bodies.

As a result, everyone just wants to sleep after the massage.

This period of time is also the period of time when they use their brains the least in many years of life.

"Our physical fitness requirements should not be the same as those of the astronauts who were born in the military before, right?"

Xu Ying also said with some uncertainty.

When they were training on this matter, someone once asked the training instructor.

It's just that they didn't give them a specific answer, just a perfunctory one.

It is said that after the training is over, they will naturally know.

"We're supposed to be experts on the space station, that's why we're going to train."

Xu Ying diverged her thinking.

It has been some time since the domestic space station was built.

Even the astronauts stationed on duty have been rotated in two batches.

According to the law of development, it is indeed time to send some experts to it.

"But it doesn't make sense." Xue Feng was still staring at the blue swimming pool.

"None of us are aerospace-related experts, and even if we are experts, they should be the first."

"Even if you are not an aerospace expert, you should be majoring in physics and mechanics."

"Both of us are engaged in architecture."

"Unless the country is going to develop real estate in space, it shouldn't let us go up in any way."

Xu Ying smiled open-mindedly: "Don't think so much, since you have this opportunity, then try to seize it." ”

"Maybe the country is going to build a house in space?"

"Thinking so much is just annoying yourself."

Xu Ying is cheerful and hardly drills.

He won't think about this kind of question that he can't think of.

Xue Feng prefers to understand the root cause of things, so he often gets caught up in these problems.

"Don't think about it, tomorrow it is said that there is a weightlessness experience course, so you can't miss it."

Xu Ying patted her friend's shoulder and turned to leave.

Everyone is an adult, and a little persuasion is enough.

Nothing else, no more to say.

In the first month of physical training, most of the content is basic.

There aren't too many thresholds.

The professional training from the second month began to be biased towards the daily training content of astronauts.

The first thing to start with is overweight and weightlessness training.

For overweight training, a large centrifuge with an arm length of more than ten meters is required to simulate a weightless environment through centrifugal force.

Weightless training is a bit more troublesome.

This is mainly achieved through the parabolic motion of the aircraft.

When flying up and down the plane, you can get a weightless experience ranging from 5 to 20 minutes at a time.

A large Il-76 stayed on the airfield.

Many people present recognized this kind of large transport aircraft, which is famous in the world.

The maximum take-off weight is 200 tons.

More than 900 were produced, far more than all other large military transport aircraft in the world.

Similar C-141 large military transport aircraft and CC-17 "Globemaster" transport aircraft, the production of which does not exceed 300 units.

"Is this the new one we introduced, or the one we brought in before?"

Xu Ying looked up and down at the Il-76 transport plane in front of him, and asked Xue Feng beside him with some curiosity.

Xue Feng, who likes to ponder, also has a sufficient understanding of military equipment.

Xue Feng carefully looked the transport plane up and down, but in the end, he didn't see anything special.

"It seems to be no different from the Il-76M we bought more than ten years ago, but it's hard to say whether it's an improved version or not."

"It is said that in the next two years, there are plans to purchase twelve new Il-76MFs."

"I don't know if it's the case."

Before the two of them could study the aircraft model.

The instructor who assisted them in the weightlessness experience was already beckoning them to get ready to board.

In the wide cargo hold, there is no 2+3 row of seats common in civil aviation.

Only on the sides of the fuselage, there are rows of fixed seats, as well as fixing buckles above the bulkheads.

"Everyone double-checked the fasteners and safety ropes to see if they were fixed in place."

As the coach spoke, he checked everyone one by one.

"If the fixation is not in place, it is easy to be thrown out directly during the weightlessness experience, and the broken tendons and fractures are light!"

There may be a hint of alarmism, but it's a risky training program.

In the past training, it is not that no one has broken himself.

Xu Ying and Xue Feng also hurriedly checked whether there was any problem with their fixing buckle and safety rope.

After the self-test was completed, I also helped my companion check it.

After tugging hard and finding that there was no problem, I was slightly relieved.

The instructor's inspection was very fast, and he tried to explain some precautions clearly before the plane took off.

Otherwise, the huge noise after the transport plane took off, it is difficult for everyone to hear clearly what he said.

"Don't panic after weightlessness starts."

"If you're nervous, hold on to the safety rope on your right hand."

"It also protects you from flying out."

Before the instructor could finish speaking, the pilot had already completed a series of preparations before takeoff.

Four D-30KP-ser.2 engines began to accelerate.

Each engine is capable of bursting out more than 12 tons of thrust.

A huge steel structure carrying 80 people and weighing 160 tons will be pushed into the blue sky.

"The engine is pretty strong."

Xue Feng whispered after the plane took off.

Xu Ying on the side could only see her friend's mouth squirming slightly.

I couldn't hear what he was saying.

The loud roar of the engine has completely muffled the sound below 80 decibels.

In the cabin, you want to be heard.

You have to be close to each other's ears and shout loudly.

It didn't take long for the cabin radio to ring in everyone's ears.

"Weightless training is about to begin, please get ready!"

It was played three times in a row.

The hearts of everyone present were hanging.

The crew members who participated in weightlessness training for the first time were worried about whether they could withstand such a weightless environment.

The coach is worried about whether there will be injuries during this training.

The pilot took control of the plane and began to dive towards the ground.

From a height of 12,000 kilometers, it galloped downward at an angle of almost 45 degrees.

The process of weightlessness is actually to make the acceleration of the descent of the aircraft constantly close to the acceleration of gravity.

Thus creating the illusion of gravitylessness.

Gravity, as a manifestation of gravity, is actually a long-range force.

It doesn't disappear into thin air.

It's just that gravity is counteracted by acceleration in the opposite direction.

Everyone in the cabin entered a state of weightlessness in an instant.

Almost everyone easily floats out of their seats without exertion.

If it weren't for the comfort of a fastening buckle and a safety rope.

They were all expected to be able to float to the top of the cabin.

In the process, the coach unfastened his buckle.

Let me show you how to move in weightlessness.

The first time weightlessness, they are just experienced.

In the subsequent weightless environment, they also have to learn how to work and live.

Even the simplest toilet on the ground has to be relearned.

Because in space, vacuum toilets are used.

There is a certain difference between the method of use and the ground.

The first weightlessness experience course didn't last long.

It lasted less than forty minutes.

This is also scientifically measured time.

Because the aircraft frequently accelerates and decelerates, it will have a certain impact on the body's internal homeostasis.

Many people even have the possibility of spitting it out.

"Gross!"

As soon as they got off the plane, several of the older crew members ran to the runway and vomited.

Xue Feng calmed down his esophagus nausea a little.

"This is really an interesting experience, if we didn't participate in the selection, it is estimated that it will be difficult to experience the feeling of weightlessness in this life."

Xu Ying smacked her mouth and said with some nostalgia.

He was also one of the few in the crowd who didn't feel sick at all.

Even people who feel very refreshed.

If you ignore the process of acceleration and deceleration, the weightless environment is still very interesting.

After losing the restraint of gravity.

You will feel that your whole body is light, as if you have returned to the state of being in the mother's amniotic fluid as a baby.

Similar to the state of diving, I feel that my body is unrestrained.

I got a lot of freedom.

If it's not a one-time experience, it consumes a lot of resources.

Xu Ying wanted to fly like this all the time.

"You're so good, everyone else can't vomit."

Xue Feng pointed to those who were vomiting a lot not far away and said.

"You still look like you want to do it again."

Xu Ying laughed, "So if there are really people among us who can be selected as astronauts, then I must be among them!" ”

Although Xu Ying was a little arrogant, Xue Feng felt that what he said was right.

Whether it is from the results of physical training, or the situation of aerospace training.

Xu Ying is the most top-notch group among these people.

At least it can be ranked in the top 10.

is even more powerful than him, and there are only a few fierce men who have won the national model worker many times when they were young, and their muscles are not weak.

"Don't be so arrogant, maybe in the next overweight training session, you will just lie down."

Xue Feng was a little unaccustomed to Xu Ying's arrogant appearance, so he persuaded him a little.

"Weightlessness is so interesting, being overweight should be even more interesting, right?"

Xu Ying didn't care much, but began to imagine what it was like to be overweight.

The next day, the training base was underground.

"We're just going to sit this guy and train?"

Xue Feng looked at the huge wheel painted with army green paint in front of him.

"It doesn't look very good, it doesn't look as powerful as yesterday's transport plane."

Xu Ying commented on the side.

Compared with the Il-76, which has a body length of 50 meters and a wingspan of 51 meters.

The overweight trainer in front of me is really a little unsightly.

With the simple green paint, it even makes people feel a little old.

"This guy can make you experience gravity of more than 8 Gs, but don't underestimate it."

The operator next to everyone, a few people in front of them ignored the overweight trainer and said a little unhappily.

In fact, they don't directly experience the gravity of 8 G's in the first place.

It is also difficult for them to directly adapt to such a large gravity.

They will start with 2 G's and let them get used to it little by little.

This continues until they are able to adapt to more than 6 G's.

The astronauts recruited before were basically professional pilots.

There is no need to worry about not being overweight at all.

Even as soon as they came up, it was a gravitational state of 8 Gs.

However, the operator also knows that these new batch of people were nothing more than experts and scholars before this.

You can't be too harsh on them.

Overweight training soon began.

Seo Ying volunteered to be one of the first members of the experience.

Got into the cabin.

"Hula!" "Hula!"

Under the action of the driving machine, the steel arm began to run at high speed.

Centrifugal force simulates an overweight state.

The few people sitting in the cabin were slapped the bulkhead.

It's like a flatbread that has been slapped on the bulkhead.

Xu Ying felt as if she was pressed against a person, and her breathing was very difficult.

It is often necessary to breathe hard to get a little oxygen.

And the accelerometer on the bulkhead shows that their centrifugal force is now only 3 times the force of gravity!

It's hard to imagine what it would be like to have 8 times gravity, 12 times gravity!

Xu Ying thought with some difficulty. (End of chapter)
