Start With a Fake University - Chapter 978 This moment is recorded in the history of spaceflight

"Fire!"

rumbling~

With the deafening sound, thick white fog rose from the bottom of the launch pad, the fuel ignited, and the huge rocket thrust pushed the behemoth in people's eyes.

Today's rocket launch, the National Aeronautics and Space Administration did not announce it to the public, that is to say, apart from the staff of the satellite launch center, the staff of the National Aeronautics and Space Administration, the research team of Wucheng University of Arts and Sciences, and the staff of Feiyue Aerospace, the There is no one else.

Not even one media TV station.

Because this rocket launch, including the experiment of rocket recovery technology, will definitely not be announced to the public. Only after the experiment is completed and successful, will the relevant information be released to the public.

"The rocket launched."

Deputy Director Chen stood in front of the floor-to-ceiling window, watching the behemoth slowly rise from the rocket launch tower, and couldn't help feeling excited.

actually.

The normal launch of the rocket is absolutely normal for Deputy Director Chen. What he is excited about is that the experiment of rocket recovery technology has finally officially started. If it is successful, how much significance will it have?

Very big!

This is what Deputy Director Chen had in mind. Maybe the final meaning will be bigger than what Deputy Director Chen thought.

"The vast sea of ​​stars is the dream of our human beings for thousands of years."

Ding Yue couldn't help but sigh.

When Deputy Director Chen heard the words, he couldn't help turning his head to look at the young and promising Principal Ding. His vision and ideas seemed to have long since been not limited to the experiment of rocket recovery technology this time. Longing for the vast sea of ​​stars.

This President Ding has great ambitions in aerospace technology. Deputy Director Chen predicts that only the aerospace major of Wucheng University of Arts and Sciences and Feiyue Aerospace will have a good development environment in the future, so his achievements may not be better than the overseas space exploration of Eagle sauce. Tech companies are worse.

"yes."

Deputy Director Chen also nodded.

Why didn't he yearn for the vast sea of ​​stars? Otherwise, he would not have become the deputy director of NASA.

"We will do it, Department Chen, do you believe it?"

Ding Yue asked Deputy Director Chen with confidence in his eyes.

"Of course, as long as we work together, anything is possible."

Deputy Director Chen continued to nod.

Although it seems that the answer is very perfunctory, in fact, Deputy Director Chen really believes that the Aerospace Administration, Wucheng University of Arts and Sciences, and other domestic colleges and universities in aerospace science and technology have now ushered in a explosive development period.

On the rocket launch tower, the satellite rocket, driven by the powerful thrust of the two booster rockets, soared towards the sky. When it first escaped from the escape tower, it was still very slow.

However, as the thrust of the rocket continued to rise, the speed naturally became faster and faster, and it began to enter the established flight trajectory normally.

Inside the building of the Jiuquan Satellite Launch Center, all I heard was the word "normal".

For rocket launches, the word "normal" is the most favorite thing for all staff to hear. After all, no one wants to hear fault alarms or other alarms. Everything is normal to let the rocket enter space and the satellite into the established orbit. , is the happiest thing.

The speed of the rocket is still increasing.

Two booster rockets can make the thrust of the rocket reach a very high altitude, so the speed of the rocket will be faster, although two booster rockets are used, the use of fuel and other aspects will also increase.

However, the corresponding experts have done the calculation of fuel usage, and finally came to the conclusion that in fact, more rockets are used as thrust, in fact, the combined fuel is more economical.

If the rocket recovery technology can be successful, the cost of the rocket will also be saved.

In this way, the cost of rocket launch will show an unprecedented and substantial reduction, so that the domestic rocket launch business will have a more competitive advantage in the international arena.

"The telemetry signal is normal."

"The track monitoring is normal."

"The rocket is in normal condition."

The rocket has entered the atmosphere, and people can't see the rocket with the naked eye. At this time, the staff of the satellite launch center and the monitoring of various monitoring points will conduct telemetry on the rocket.

"After the satellite is sent into the near space, it's time to start separating the rocket."

Deputy Director Chen said excitedly.

"Uh-huh."

Ding Yue nodded and said, "Is this satellite a near-Earth satellite?"

"Yes, it is mainly to build an auxiliary satellite of a satellite system for water monitoring." Deputy Director Chen replied.

"Then when the rocket sends this satellite into near-Earth space, it will be separated, and after the separation, the rocket recovery control system will be activated."

Ding Yue is quite familiar with the rocket recovery technology developed by Wucheng University of Arts and Sciences.

Deputy Director Chen did not speak at this time, but took a deep breath.

After all, this moment is really critical and important for the domestic aerospace field. What Deputy Director Chen is thinking at this moment is that nothing should happen, and the experiment must be successfully completed.

Ding Yue also thought so at this moment.

I don't want to see my Wucheng University of Arts and Sciences and Feiyue Aerospace lose face in front of the National Aeronautics and Space Administration. It would be embarrassing if they fail, but Ding Yue can't guarantee 100% success. Who can say that is 100% accurate?

Back in the day, Akers of Eagle Sauce Space Exploration Technology Co., Ltd. had many failures when it came to rocket recovery. He blew up a lot of rockets, and finally got the maturity of rocket recovery technology.

but.

The rocket recovery technology research team of Wucheng University of Arts and Sciences also assured Ding Yue that a 100% success rate is unlikely, but they can do their best to ensure at least a 99% success rate.

This made Ding Yue feel more at ease.

"The rocket is ready to separate."

Inside the satellite launch center, the command for the rocket to prepare for separation sounded.

After the rocket is separated, the satellite will start to operate according to the established orbit, and the launch of the satellite is basically successful, and the rest is the deployment of the satellite's solar panels and other work.

This is also the reason why NASA chose to launch such a near-Earth satellite. After all, compared to other satellites or spacecraft launches, it is simpler.

After the satellite rocket is separated, the rocket is ready for recovery.

At this time, the rocket has pushed the satellite into the near-Earth outer space. At this time, it is definitely impossible to separate and fall down like the previous rocket, because in the near-Earth outer space, the earth's gravity is already very difficult. It has an effect on the rocket, so if the rocket is turned off, it will float in near space like space junk.

However, these two rockets now have sophisticated recovery systems, and the fuel has not been used up. The rockets also have their own propulsion systems for adjusting the direction.

"Separation countdown, ten, nine, eight, seven, six, five..."

"Three, two, one..."

boom!

The explosion bolts of the two launch vehicles exploded, and the rocket and the satellite were officially separated, and the separation was relatively successful.

The satellite began to move towards its intended orbit. After the two rockets separated, the rocket recovery control system was activated for the first time.

"Turn on the rocket recovery control system!"

When the satellite is successfully launched, then it is the turn of the Wucheng University of Arts and Sciences team and Feiyue Aerospace to operate. After all, this rocket recovery technology was developed by them, and naturally it is up to them to personally carry out the whole process. operate.

In fact, the rocket recovery technology is basically fully intelligent, and it is automatically recovered according to the preset route. What the Wucheng University of Arts and Sciences team and the staff of Feiyue Aerospace need to do is to always pay attention and a small amount of controlled operations. , if there is any accident, it must be ensured that the problem can be solved as soon as possible.

"Chen Department, here is an online real-time simulation based on the real-time state of the rocket."

Ding Yue pointed to the big screen, where two rockets began to adjust their direction from near-Earth outer space, and the simulated picture when they were recovered.

This simulation screen is based on the real-time state of the rocket, so it has a high reference value. After all, when people are on the ground, they cannot observe the state of the rocket in near-Earth outer space with the naked eye. Only the real-time state of the rocket can be simulated.

I saw on this big screen that after the two launch vehicles separated from the satellite, they were aligned, and then they started to change their direction.

When the satellite is sent into outer space, the head of the rocket is directed towards outer space, but you will not fall naturally in outer space, because the gravitational effect of the earth has basically disappeared.

Therefore, at this time, the rocket's own propulsion is needed to return and leave the near-Earth outer space and enter the earth's atmosphere.

Only after the rocket enters the earth's atmosphere will it begin to fall under the influence of the earth's gravity.

Therefore, the two rockets are adjusting the direction synchronously, which is the so-called U-turn.

Through the real-time simulation picture on the big screen, it can be seen that the U-turn of the two rockets went smoothly. When the U-turn reached a certain level, the rockets were ignited again.

Exactly!

The fuel in the rocket is not exhausted.

Because the rocket fuel prepared in the whole process is to support the continued use of the rocket when it is recovered.

When the two rockets reversed their directions, the rockets ignited and pushed again, pushing the two launch vehicles from near-Earth outer space into the atmosphere.

And when the two launch vehicles enter the atmosphere, they will make a second reversal, because the speed is not so fast here, it is best to reverse the direction.

It is also the only time when the direction can be reversed without losing too much power. This is also the method used by Eagle Sauce's Space Exploration Technology Company. Their top rocket recovery technology is only to recover two launch vehicles.

The reason why after entering the atmospheric region, it is necessary to turn the direction again immediately, so that the tail of the rocket is aimed at the earth, and the head is aimed at the sky, mainly because the speed of the rocket here is not very fast, and it is very convenient to change the direction.

And if the rocket is allowed to enter the atmosphere without changing the direction, then the rocket will fall down with its head facing the ground and its tail facing the air, and the speed will become faster and faster, and it will be difficult to reverse the direction at that time.

Moreover, when the rocket is about to reach the ground, the tail of the rocket needs to be ignited again to form resistance to slow down the speed of the rocket, so that the rocket can be slowly landed.

So, if you don't turn the direction after entering the atmosphere, then there is basically no chance to turn the direction later, and then the rocket will not be able to re-ignite to form reverse thrust resistance.

"After entering the atmosphere, the direction change is successful, then you only need to hand it to the ground, ignite the rocket, and then ask the whereabouts, even if it is a success, right?"

Deputy Director Chen clenched his left hand tightly, his palm was sweating, looked at Ding Yue and asked.

"right."

Ding Yue nodded slightly.

It seems that it is so simple, but the whole process must be precisely controlled, and there must be no mistakes. Otherwise, if there is any problem due to the angle or speed when it reaches the ground, then it will not be possible at that time. Okay, basically it will cause the rocket to deviate from the landing, and then it will land with a bang, explode, and finally fail!

But for now.

The fall of the two launch vehicles is under control. The staff of Wucheng University of Arts and Sciences and Feiyue Aerospace are doing their best to control all the data of the two rockets within their controllable range. Inside!

finally!

The rocket is getting closer and closer to the ground.

People on the ground can already see two dots appearing in the sky.

Then these two points became more and more obvious, and then everyone could see that these two points were actually two launch vehicles, and they were falling at a high speed.

"falling down!"

Someone shouted excitedly.

This sentence sounds simple, but in fact it is not so easy.

Because of the whole process of "falling down", UU Reading www.uukanshu.com requires relevant personnel to accurately control the data.

"Ready to set fire!"

This is the last ignition of the rocket. This time, the rocket has been ignited several times for the mission of launching satellites.

"Fire!"

Boom!

After the two launch vehicles reached a predetermined height from the ground, they were ignited!

The flame was ejected from the tail of the rocket, forming a strong reverse thrust resistance, and the descending speed of the rocket began to gradually decrease.

The staff of the Jiuquan Satellite Launch Center saw that although the two rockets were being told to fall, after the ignition formed a reverse thrust, the speed dropped. The closer they were to the ground, the slower their speed became. When there were still about 100 meters on the ground, the speed of the rocket was basically very slow, reaching a level of complete control.

The support frame unfolds!

Then.

The two rockets descended slowly in parallel and landed in their predetermined recovery areas respectively. The support frame firmly supported the rockets and stood there firmly.

The picture at this moment is so beautiful.

At this moment, it will be recorded in the history of spaceflight of the Xia Kingdom...
