"ignition!"

Rumble~

Along with the deafening sound, thick white mist rose from the bottom of the launch pad, the fuel was ignited, and the huge rocket thrust pushed up the behemoth in people's eyes.

Today’s rocket launch was not announced to the public by the National Aeronautics and Space Administration. That is to say, except for the staff of the Satellite Launch Center, the National Aeronautics and Space Administration, the research team of Wucheng University of Arts and Sciences, and the staff of Feiyue Aerospace on the scene, There is no one else.

Not even one media station.

Because this rocket launch includes an experiment on rocket recovery technology, it will definitely not be announced to the outside world. Only after the experiment is completed and successful will the relevant information be released to the outside world.

"The rocket launched."

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

actually.

For Deputy Director Chen, it is absolutely normal for the rocket to launch normally. What he is excited about is that the experiment of rocket recovery technology has finally officially begun. If it is successful, how significant will it be?

Big!

This is what Deputy Director Chen has in mind, and its ultimate significance may be greater than what Deputy Director Chen thinks.

"The vast sea of ​​stars has been our human dream for thousands of years."

Ding Yue couldn't help but sigh.

Upon hearing this, Deputy Director Chen couldn't help but turn his head and look at the young and promising Principal Ding. His vision and thinking seemed to have long been no longer limited to this experiment of rocket recovery technology. Instead, Yearning for the vast sea of ​​stars.

President Ding has great ambitions in aerospace technology. Deputy Director Chen predicts that in the future, only the aerospace major of Wucheng University of Arts and Sciences and Feiyue Aerospace will have a good development environment, so his achievements may not be as good as the space exploration of Yingjiang overseas. Tech's Akers is worse.

"yes."

Deputy Director Chen also nodded.

Why didn't he long for the vast sea of ​​stars? Otherwise, he would not have become the deputy administrator of the National Aeronautics and Space Administration.

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

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

“Of course, if 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 National Aeronautics and Space Administration, Wucheng University of Arts and Sciences, and the aerospace science and technology majors of other domestic universities have now ushered in a period of explosive development.

On the rocket launch tower, the satellite rocket, driven by the powerful thrust of the two booster rockets, rose into the sky. When it first left the escape tower, it was still very slow.

But as the thrust of the rocket continues to increase, the speed naturally becomes faster and faster, and it begins 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 what all staff like to hear most. After all, no one wants to hear a fault alarm or other alarm. Everything is normal for the rocket to enter space and the satellite to enter 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 height, 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, corresponding experts have done calculations on fuel usage and finally concluded that using more rockets as thrust actually saves more fuel overall.

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

As a result, the cost of rocket launches will show an unprecedented significant reduction, making the domestic rocket launch business even more competitive internationally.

"Telemetry signal is normal."

"Track monitoring is normal."

"The rocket is in normal condition."

The rocket has entered the atmosphere, and people cannot see the rocket with the naked eye. At this time, the rocket is remotely measured through the staff of the satellite launch center and the monitoring of various monitoring points.

"After the satellite is sent into near space, it is 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 establish an auxiliary satellite for a water conservancy monitoring satellite system." Deputy Director Chen replied.

"Then when the rocket sends this satellite into near-Earth space, it will separate. After the separation is completed, the rocket recovery control system will be activated."

Ding Yue is relatively familiar with the rocket recovery technology developed by his 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 too critical and important for the domestic aerospace field. What Deputy Director Chen is thinking about at this moment is that nothing should happen and the experiment must be completed smoothly.

Ding Yue was thinking the same thing at the 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. If it fails, it will indeed be a bit embarrassing, but Ding Yue cannot guarantee 100% success. This kind of technological experiment Who can be 100% sure about things?

Looking back on those days, Akers of Yingjiang Space Exploration Technology Co., Ltd. also experienced many failures when recycling rockets. Many rockets exploded, and finally the rocket recycling technology matured.

but.

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

This actually made Ding Yue feel more at ease.

"The rocket is preparing to separate."

In the satellite launch center, the order for the rocket to prepare for separation rang out.

After the rocket separates, the satellite will start operating according to the established orbit. The launch of the satellite is basically successful. All that is left is to deploy the satellite's solar panels and other work.

This is also the reason why the National Aeronautics and Space Administration chose to launch such a near-Earth satellite. After all, it is simpler than the launch of other satellites or spacecrafts.

After the satellite rocket is separated, the rocket will be 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 like the previous rocket, because in the near-Earth outer space, the gravity of the earth is already very difficult. It has an effect on the rocket, so if the rocket stalls, it will float like space junk in near space.

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

"Countdown to separation, ten, nine, eight, seven, six, five..."

"Three, two, one..."

boom!

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

The satellite began to move towards its planned orbit. After the two rockets separated, the rocket recovery control system was activated immediately.

"Turn on the rocket recovery control system!"

After the satellite is successfully launched, then it is the turn of the team from Wucheng University of Arts and Sciences and Feiyue Aerospace to operate. After all, they developed this rocket recovery technology, so naturally they have to carry out the entire process in person. operate.

In fact, the rocket recovery technology is basically fully intelligent and automatically recovers according to the preset path. All the Wucheng University of Arts and Sciences team and Feiyue Aerospace staff need to do is to pay attention at all times and perform a small amount of controlled operations. , if any accident occurs, we must ensure that the problem can be solved as soon as possible.

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

Ding Yue pointed to the big screen, where there was a simulation of two rockets adjusting their direction and recovering from near-Earth space.

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

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

When sending a satellite into outer space, the head of the rocket points toward 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, leaving near-Earth space and entering 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 their directions simultaneously, which is the so-called U-turn.

From the real-time simulation screen 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 rocket was ignited again.

That's right!

The fuel in the rocket is not exhausted.

Because the rocket fuel prepared throughout the process is to support the continued use of the rocket during recovery.

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

When the two launch vehicles enter the atmosphere, they will change direction for the second time. Because the speed is not that fast here, it is best to change 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 Yingjiang's Space Exploration Technology Company. Their most advanced rocket recovery technology can only recover two launch vehicles.

The reason why after entering the atmosphere area, it is necessary to immediately change the direction again, so that the tail of the rocket is pointed at the earth and the head is pointed 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 its direction, then the rocket will fall with its head towards the ground and its tail towards the air, and the speed will become faster and faster, and it will be difficult to change its direction by then.

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 rocket, so that the rocket can land slowly.

Therefore, if you do not change direction after entering the atmosphere, there will basically be no chance to change direction later, and then you will not be able to ignite the rocket again to form reverse thrust resistance.

"After entering the atmosphere and successfully changing direction, you only need to hand it to the ground, ignite the rocket, and then ask about the landing. It will be considered a success, right?"

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

"right."

Ding Yue nodded slightly.

It seems so simple, but the whole process must be controlled accurately without making any mistakes. Otherwise, if there is any problem due to angle or speed when reaching near the ground, then it will not be possible. After finishing it, it will basically cause the rocket to deviate when it lands, and then it will land with a bang, explode, and finally fail!

But for now.

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

finally!

The rocket is getting closer to the ground.

People on the ground can already see two points 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 high speed.

"falling down!"

Someone shouted excitedly.

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

Because the entire process of "falling" requires relevant personnel to accurately control the data.

"Get ready to light the fire!"

This is the last ignition of the rocket. On this mission of launching a satellite, the rocket has been ignited several times.

"ignition!"

boom!

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

Flames ejected from the tail of the rocket, forming a strong thrust resistance, and the rocket's descent speed also began to gradually decrease.

The staff at the Jiuquan Satellite Launch Center saw that although the two rockets were falling, their speed dropped after ignition and reverse thrust. The closer they were to the ground, the slower their speed became. Finally, at the distance When the ground was still about a hundred meters away, the speed of the rocket was basically very slow, reaching a level of complete control.

The support frame unfolds!

Subsequently.

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

The picture at this moment is so beautiful.

This moment will be recorded in the annals of Xia’s aerospace history...
