I really have special powers

Chapter 184 Entering Space
Therefore, the mere 47-ton rocket model in front of him was completely within his tolerance.

"call!"

With a breath, everyone in the distance saw the rocket model being lifted up silently. There was no loud bang and no other movement. It was like the gravity of the planet had lost its restraint on the rocket model, so that this The thing with a mass of 47 tons actually levitated into the air, and flew into the sky with Yu Zetong.

"It's really...unbelievable unless you've seen it with your own eyes."

Hong Bin wiped his glasses with a handkerchief. The wind and sand in the desert were very strong, and soon the glasses were completely covered with dust.

Although it is just a rocket model, it is still equipped with a lot of sensor equipment. After Yu Ze lifts the rocket model up, the telemetry system will automatically transmit various sensor data on the rocket model back to the ground to provide them with monitoring and analysis. .

Therefore, even when Yu Ze and the rocket model are invisible to the naked eye, they can still find Yu Ze on the equipment monitoring screen.

"Dongfeng Optics USB radar tracking is normal."

"The telemetry signal is normal."

"Jiuquan tracking is normal."

This place is very close to Jiuquan. They can clearly see the shadow of the rocket model through optical telemetry. However, compared to the huge rocket model at this distance, Yu Ze himself is too small and only a small figure on the screen. black spots.

"The speed is still a bit slow."

Dong Shuxian pondered.

Yu Zetuo held up the rocket model and soared at a speed close to the speed of sound. It looked terrifying, but compared with the speed of a real rocket launch, it seemed insignificant.

Even so, within one minute, Yu Ze held up the rocket model and soared to an altitude of 1 kilometers. Two minutes later, he reached an altitude of 15 kilometers, and three minutes later, he reached an altitude of 2 kilometers.

It only took Yu Ze five minutes to reach the 80-kilometer dividing line of the Carmen Line.

In fact, it is different from the real rocket flight track. After the real rocket is ignited and takes off, it must first fly in the thick atmosphere, cross the speed of sound, pass through the maximum dynamic pressure zone, and then fly out of the atmosphere, and finally send the spacecraft into a predetermined orbit.

This kind of flight process needs to go through the vertical take-off section, the programmed turning section, and the orbit-entry section. The vertical take-off section is easy to understand, that is, the rocket flies vertically upward, but soon, the rocket will fly in the launch direction according to the predetermined pitch angle. This This is all to reduce air resistance, avoid aerodynamic loads and aerodynamic interference, and fly at an angle of attack close to 0° only after successfully crossing the speed of sound.

The rocket model Yu Ze lifted was different. He ascended vertically from beginning to end, forcibly overcoming the constraints of the earth's gravity. The distance was far shorter than the actual rocket launch track. This was why his speed was not as fast as the rocket. But in This is because the time of final exit from the atmosphere is almost the same.

Near the Karman line, many first-stage rockets can separate, and the second-stage rockets are used to boost acceleration. Originally, according to common sense, when the second-stage rocket is ignited at this time, it has a speed of 3 kilometers per second to 6 kilometers per second. If the initial speed is high, then only a small acceleration is needed to increase the speed to more than 8 kilometers per second.

But at this time, the rocket model lifted by Yu Ze rose vertically to near the Kármán line. Even if it tilted slightly in an arc later, the speed could be regarded as zero relatively speaking.

But what’s interesting is that there are two solutions at this time.

One is that the second-stage rocket can be improved. It is much easier to increase the speed at this altitude than the first-stage rocket to send the spacecraft near the Karman line.The second idea is that the atmospheric concentration near the Kármán line is quite low, almost like a vacuum. When Yu Ze continues to lift the rocket model to an altitude of 100 kilometers, he can easily assist the rocket model in accelerating without atmospheric interference.

When the speed of the rocket model gets faster and faster, and the rocket's average speed reaches the orbiting speed, Yu Ze only has to overcome the influence of gravity, and he only has to overcome the centrifugal force of inertia, which makes it easier for him.

As a result, Hong Bin and others on the ground saw that the speed of the rocket model quickly increased to 8.6 kilometers per second. At this time, if the second-stage rocket was launched again, there would be no problem in completing the direct entry into low-Earth orbit. of. "The trial was perfect."

Wan Ronglong witnessed the whole process and had to admire Hong Bin's thinking.

"What a pity, why are there only six years left?"

At the same time, he had to "resent".

If there hadn't been that dwarf planet that broke into the solar system unscrupulously, in a peaceful era, Yu Ze's ability would have saved a lot of space costs and time. He could even train a few more times and come up with a few more ideas and solutions. One or two The three-stage propulsion system can be omitted, and Yu Ze can directly take the spacecraft to the predetermined orbit.

In that case...I can't imagine what a beautiful scene it would be.

The test is over.

Yu Ze reduced the speed of the rocket model. Because it was a model, it could be completely burned if allowed to enter the atmosphere without causing harm to the ground.

And when he was suspended in space 120 kilometers above the earth, staring at the earth and the stars in the sky, he couldn't help but be shocked by the magnificence and beauty of the universe.

Without the interference of the atmosphere, the starry sky is so beautiful, both in terms of brightness and quantity, it is much stronger than when seen on the earth.

"Such a beautiful starry sky, but not something ordinary people can see with their own eyes."

Yu Ze was in a spacesuit and couldn't really touch space even with his arms stretched out.

After admiring the beautiful space scenery for a while, Yu Ze felt a sense of loneliness and fear again.

Although the starry sky is beautiful, it is not the home of human beings. It still contains great dangers. Without the protection of the earth, humans would not be able to survive for a long time in the starry sky.

So how lucky humans are to have the earth.

But soon, this protection is about to disappear, and mankind will face real dangers, malice coming from the deep space of the universe.

However, human civilization is too immature at present, so immature that it does not have the strength to deal with such danger and malice. Without Yu Ze's existence, the current idea of ​​​​keeping the fire of human civilization would not be proposed, let alone a real implementation plan.

"Let's go back."

Yu Ze turned around and slowed down his orbiting speed, falling towards the surface of the earth.

In order to prevent a thermal barrier from occurring when re-entering the atmosphere, he needed to reduce his falling speed. It took him a little longer than the ascent to reach an altitude of [-] meters above the ground.

What he didn't expect was that he ascended from the Badain Jaran Desert, not far from Jiuquan, and flew for a certain distance in space. When he landed on the surface, he used Beidou to locate it. He actually arrived at the eastern edge of the Kubuqi Desert, about [-] meters away from Baotou. Not too far.

If we had to wait for Hong Bin and Wan Ronglong to arrive by car, the fastest way would be to take the G6 Expressway, which would take more than ten hours of driving and cover a thousand kilometers.
