A big country of aerospace with black technology

The current operating status of the rocket is always displayed on the screen in the control center.

Everyone is very nervous now, the rocket launch has reached the final touch.

No one wants to fail at a time like this.

Zhang Xingyang even stood up nervously, half-slanting his body and staring at the constantly changing screen with various data.

"Three-stage rocket fires."

The young man in charge of broadcasting the operating status of the rocket was obviously a little scared by the current state of the rocket.

After a few seconds, he swallowed a mouthful of saliva and said:

"fail!"

Zhang Xingyang felt that his body seemed to be exhausted at this moment, and he was about to fall to the console in front of him.

Fortunately, Geng Bo at the side had sharp eyesight and quick hands, and helped him up.

"Try secondary ignition!"

Although Zhang Xingyang did not personally issue an order, everyone still dealt with it according to the emergency plan prepared not long ago.

Want to control a three-stage rocket motor for secondary ignition.

The third-stage rocket engine of the Chang-3 rocket uses a hydrogen-oxygen machine with a relatively low thrust.

Using liquid hydrogen and liquid oxygen as the energy source of the engine, the working time is not very long, so the working requirements for the engine are not particularly strict.

It is precisely because of this.

The time to rescue the three-stage rocket engine is actually very short.

If it is not possible within this short period of time, the rocket engine will be re-ignited.

Then the third-stage rocket, together with the fairing containing the satellite, will fall to the ground under the gravitational force of the planet.

Even if the fairing is thrown out in advance, find a way to rely on the power of the satellite itself to move.

But in doing so, the satellite cannot reach the orbital height it should have reached.

Even if it barely reaches a working orbital altitude, the service life of the satellite itself will be greatly shortened due to excessive fuel consumption.

The original design can theoretically be used for fifteen years, but after such an operation, it may not have a service life of fifteen months.

Moreover, the satellite's range of action will be greatly reduced compared to the original design range.

The electrical signal for the secondary ignition of the rocket motor reaches the ignition device within one thousandth of a second.

The people in the control center are all nervously waiting for the result of the second ignition.

If the ignition fails again this time, the three-stage rocket can basically give up the treatment and be sentenced to death.

No one knows the current status of the third pole of the Chang-3 rocket, which is far away in the ionosphere of the upper atmosphere.

Most of the people in the center prayed silently in their hearts. Although the scientific researchers present were basically atheists, everyone still expected a miracle to happen at this time.

Time passed by second by second.

Although it has only been a dozen seconds since the radar monitoring to the failure of the ignition of the three-stage rocket engine.

But afterward, many people still think that this short period of ten seconds is longer than the past many hours.

On Zhang Xingyang's forehead, there were layers of sweat constantly.

Since coming to this era, Zhang Xingyang has never been so nervous.

In my mind, I kept simulating the state of the rocket engine.

Although in the process of several fast simulations, the result of successful secondary ignition can be obtained.

But the real world does not need to talk about logic after all, and all kinds of emergencies are possible.

Therefore, Zhang Xingyang's tension could not be eliminated.

"Three-stage rocket engine, the second ignition was successful!"

The young man in charge of broadcasting the operating status of the rocket shouted very excitedly.

Zhang Xingyang stared at the big screen in front of him with his originally low head.

The above shows that the secondary ignition of the three-stage rocket motor has been successful, and it has begun to move to the predetermined orbit.

It worked!

Zhang Xingyang couldn't help shouting in his heart.

No one is more aware of the importance of this than him.

If it fails this time, the reputation of Longguo's space launch will be rotten internationally, and no overseas company is willing to hand over commercial launch missions to Longguo.

But fortunately, the second ignition of the three-stage rocket was successful, and there was basically no failure behind it.

Even if the satellite's solar panels fail to deploy, that has nothing to do with the rocket.

When I came to this era, I finally did something that truly changed history.

"Xingyang, we succeeded."

Geng Bo on the side also said very excitedly.

Zhang Xingyang also let out a long sigh of relief, and said happily:

"Yeah, the three-stage rocket engine has been ignited successfully, and the rest is basically smooth sailing!"

In fact, the same is true. After the three-stage rocket engine starts working, it will soon be able to send the satellite to its proper orbit.

The big screen shows a three-stage rocket with a fairing, and its altitude is getting higher and higher.

Of course, at this time, the third-stage rocket is also getting farther and farther away from the launch base. At this time, only the ocean-going monitoring ships above the ocean can continuously track the position of the rocket.

This is also because the Dragon Kingdom at this time has not yet deployed too many monitoring satellites in space.

Otherwise, only a few satellites are needed to continuously monitor the rocket's flight trajectory.

The signal of the ocean-going monitoring ship is continuously transmitted to the rocket launch base through the reflection of the atmospheric ionosphere.

"Three-stage rocket breaks away!"

The third-stage rocket and the satellite have reached the predetermined orbital altitude, and the blue star is in the geostationary orbit.

The geostationary orbit is also the orbit in which many communication satellites are located. Here, the position of the satellite is seen from above the surface of the planet and remains unchanged no matter what time it is, so it is called a geostationary orbit.

Of course, this orbit is located above the equator.

"The satellite has successfully entered orbit!"

Accompanied by a shout from the announcer.

In the entire control center, voices erupted.

Everyone cheered the success of this moment, no matter men, women or children, regardless of their original job functions.

They hugged each other tightly with those around them.

shouted:

"We made it!"

Zhang Xingyang hugged Su Xiao beside him tightly, and kept shouting:

"Successful!"

"We made it!"

Although Su Xiao seemed a little shy, Zhang Xingyang obviously didn't think too much about it.

Turning her head, she hugged Geng Bo beside her again, patted his back vigorously, and kept repeating her own words.

At this time, even the reporters who were not aerospace workers were infected by the excitement.

He kept hugging and cheering with the people around him.

The astronauts present were not hesitant to share their happiness with others.

As for the little brother carrying the camera, he kept recording the lively scenes in the control center.

After many years, this video record will be recorded in many documentaries and become a proof of the country's aerospace industry.
