A big country of aerospace with black technology

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

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

Have a healthier and stronger body.

"Old Xue, your physical fitness has improved rapidly recently!"

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

They had just finished swimming training.

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

"Without you, it would take me a lot of time to swim optically."

Xue Feng said angrily.

Xu Ying grew up on a boat. When she was young, her water skills were as good as those of Bai Tiao in the waves.

When Xue Feng was a child, his home was in the northwest, let alone learning to swim.

There isn't even a pond near my home.

The water supply depends entirely on digging water reservoirs.

Therefore, before this, it took him several classes just to learn to hold his breath.

Although Xu Ying has not been swimming for a long time after working these years, the foundation she once had is still there after all.

With a little familiarity, you can swim in the water and make flowers appear.

"That's right. When I was a kid, your current level would have been at the level of a district-level swimming team at least."

Xu Ying continued to tease.

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

"Do you think we can really become astronauts?"

"We are still far away from the requirements of astronauts, right?"

Within a month, most people's physical fitness level is at best restored to that of their youth.

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

Most people are aware of this.

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

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

There are professional doctors and physical trainers in the base.

After the heavy training tasks every day.

They will be given muscle relaxation and relief.

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

This also leads to the fact that after the massage, everyone just wants to sleep.

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

"Our physical fitness requirements shouldn't be the same as those of previous military astronauts, right?"

Xu Ying also said with some uncertainty.

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

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

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

"We should be going to the space station as experts, so we are allowed to train."

Xu Ying spread her thoughts.

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

Even the astronauts stationed there have been rotated through two batches.

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

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

"None of us are experts in aerospace. Even if we are experts, they should go first."

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

"Both of us are engaged in construction."

"Unless the country plans to develop real estate in space, we should not be allowed to go up there."

Xu Ying smiled openly: "Don't think so much. Since you have this opportunity, try to seize it."

"Maybe the country wants to build a house in space?"

"Thinking so much is just causing trouble for yourself."

Xu Ying is a cheerful person and rarely gets into trouble.

He won't think about this kind of question that he can't find the answer to.

Xue Feng prefers to understand the root causes of things, so he often gets stuck in these problems.

"Don't think about it, there is said to be a weightlessness experience course tomorrow, don't miss it."

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

We are all adults and a little persuasion is enough.

There is no need to say anything else.

Most of the physical training in the first month is basic content.

There aren't many barriers.

The professional training starting from the second month began to focus on the daily training content of astronauts.

The first thing to start is overweight and weightless training.

Overweight training requires the use of a large centrifuge with an arm more than ten meters long, which uses centrifugal force to simulate a weightless environment.

Weightless training is a little more troublesome.

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

When flying up and down the plane, you can experience weightlessness for 5 to 20 minutes each time.

A large IL-76 is parked at the airport.

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

The maximum take-off weight is 200 tons.

The production volume exceeds 900 aircraft, far exceeding all other large military transport aircraft in the world.

The production of similar C-141 large military transport aircraft and CC-17 "Globemaster" transport aircraft does not exceed 300 aircraft.

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

Xu Ying looked up and down at the IL-76 transport plane in front of her, and curiously asked Xue Feng beside her.

Xue Feng, who likes to ponder, also has sufficient knowledge in military equipment.

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

"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 is an improved model."

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

"I don't know if this is it."

Before the two of them could figure out the model of the aircraft.

The instructor assisting them in the weightless experience had already greeted them to prepare to board the plane.

In the large cargo hold, there is no 2+3 arrangement of seats that is common in civil aviation.

There are rows of fixed seats only on both sides of the fuselage, as well as fixed buckles above the bulkhead.

"Everyone should carefully check the fasteners and safety ropes to see if they are fixed in place."

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

"If it is not fixed in place, it will be easy to be thrown out during the weightless experience. Even if you fall and break your muscles and bones, it will be minor!"

Although there is a hint of alarmism, this is indeed a very high-risk training project.

In the past training, it is not that no one has suffered injuries and fractures.

Xu Ying and Xue Feng also quickly checked whether there were any problems with their fixed buckles and safety ropes.

After the self-examination was completed, he also helped his companion to check it.

After tugging hard and finding that there was no problem, I breathed a sigh of relief.

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

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

"Don't panic after weightlessness begins."

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

"It can also protect you from flying out directly."

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

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

Each engine is capable of producing more than 12 tons of thrust.

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

"The engine is quite powerful."

Xue Feng whispered after the plane took off.

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

But I couldn't hear what he was saying at all.

The huge roar of the engine has completely covered up the sound below 80 decibels.

Inside the cabin, you want your voice to be heard.

You have to press into the other person’s ear and yell loudly.

Not long after, the cabin announcement rang in everyone's ears.

"Weightless training is about to begin, please be prepared!"

Played it three times in a row.

The hearts of everyone present were in suspense.

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

The coaches are worried about whether there will be injuries during this training.

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

From an altitude of 12,000 meters, it galloped downward at an angle of nearly 45 degrees.

The process of weightlessness actually causes the acceleration of the aircraft's descent to continue to approach the acceleration of gravity.

This creates the illusion of weightlessness.

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

It won't disappear in a vacuum.

It's just that the effect of gravity is offset by acceleration in the opposite direction.

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

Almost everyone levitated easily from their seats without exerting any effort.

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

They could probably all float to the top of the cabin.

In the process, the coach untied his own fastening buckle.

Let me show you how to move without gravity.

They were just experiencing weightlessness for the first time.

They will also have to learn how to work and live in the subsequent weightless environment.

Even the simplest toilet on the ground has to be learned again.

Because in space, vacuum toilets are used.

The method of use is somewhat different from that on the ground.

The first weightlessness experience course did not last long.

It only lasted less than forty minutes.

This is also a scientifically measured time.

Because aircraft frequently accelerate and decelerate, it will have a certain impact on human body balance.

Many people may even vomit it out directly.

"vomit!"

After getting off the plane, several older passengers ran to the runway and vomited.

Xue Feng calmed down the nausea in his esophagus a little.

"This is really an interesting experience. If we hadn't participated in the selection, it would be difficult for us to experience the feeling of weightlessness in our lives."

Xu Ying smacked her lips and said with some nostalgia.

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

Someone who even feels great.

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 has become lighter, as if you have returned to the state of being in the mother's amniotic fluid when you were a baby.

It is similar to the state when diving, and the body feels unrestrained.

I gained great freedom.

If you don't experience it once, it will consume a lot of resources.

Xu Ying almost wanted to keep flying like this.

"You're so awesome, everyone else is vomiting."

Xue Feng pointed to the people not far away who were vomiting violently and said.

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

Xu Ying laughed, "So if anyone among us can really be chosen as an astronaut, then I must be among them!"

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

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

Xu Ying is the most outstanding among these people.

At least it can be ranked in the top ten.

Even more powerful than him are those fierce men who have won the National Model Worker title many times when they were young and have strong muscles.

"Don't be so arrogant. Maybe you will just lie down during the next overweight training session."

Xue Feng couldn't stand Xu Ying's arrogance, so he tried to persuade her a little.

"The weightlessness part is so interesting, so 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 with this guy and train?"

Xue Feng looked at the huge wheel painted in military green in front of him.

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

Xu Ying commented from the side.

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

The overweight training device in front of me is really ugly.

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

"This guy can let you experience more than 8 G of gravity, so don't underestimate it."

The operators beside everyone looked down upon the overweight training equipment and said somewhat unhappily.

In fact, they won't experience 8 G's of gravity directly at first.

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

I will start with 2 G and let them adapt little by little.

Continue until they can adapt to more than 6G.

The astronauts recruited before were basically professional pilots.

There is no need to worry about not adapting to being overweight.

Even as soon as they came up, they were in a gravity state of 8 G.

But the operator also knows that these new batch of people were just experts and scholars before this.

Don't be too harsh on them.

Overweight training begins quickly.

Xu Ying volunteered to become the first member to experience it.

Sit inside the cabin.

"Hoola!" "Hoola!"

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

Centrifugal force simulates excess weight.

He slapped several people sitting in the cabin against the cabin wall.

It was like a piece of pie that was photographed on the bulkhead.

Xu Ying felt as if someone was pressing on her body, and it was very difficult to breathe.

It is often necessary to take a deep breath to get some oxygen.

The accelerometer on the bulkhead shows that their current centrifugal force is only equivalent to 3 times gravity!

It’s really unimaginable what it would be like with 8 times gravity and 12 times gravity!

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