As the speed and altitude of the rocket continued to increase, it quickly disappeared from everyone's eyes, so everyone turned their attention to the rocket flight animation inside the control room.

At the same time, because the height and speed of the rocket have reached very high at this time, various military bases or military radar stations in the province or outside the province have also discovered the rocket that is slowly rising and detected the rocket in real time. attitude and direction of flight.

But in fact, the rocket has already flown out of the coastline at this time, and it is already in the sky above China's coastal waters. After all, the straight-line distance between Tiangong Technology's rocket launch pad and the coastline is only ten kilometers, and the rocket at this time With a speed of several hundred meters per second, it doesn't take long to fly to the sky near the sea.

Of course, even in this way, the military did not relax at all. After all, even in the offshore sea, there are a large number of ships sailing. Even if the rocket flies over the high seas, it may not be safe. When it was in the sky, the rocket's flying height and speed were already very high. Even if something happened, the rocket would definitely simplify and explode into pieces immediately.

So when the height of the rocket reached a certain level, Wang Bin and the launch personnel present felt much more relaxed.

"The rocket has left the atmosphere, ready to open the fairing and release the satellite." When the rocket finally flew out of the atmosphere, the commander on the scene immediately ordered.

At the same time, the rocket is also under the control of the controller, and the fairing of the rocket is slowly opened to both sides, preparing to release the satellite after the rocket reaches the predetermined orbit.

Of course, if it is another rocket, after the rocket leaves the atmosphere, it will directly abandon the fairing like the rocket they launched at the South China Sea launch site before, and it will not open to both sides.

But the one improved by Wang Bin and Tiangong Technology is different. Since Tiangong Technology wants to recover the rocket as a whole, it did not directly discard the fairing after breaking through the atmosphere, but prepared to recover the rocket. Recovered together with the fairing.

Of course, retaining the fairing also has a very important effect, that is, when the rocket returns to the atmosphere, because the material of the fairing is very high temperature resistant, it can also be used by the rocket when it returns to the atmosphere. generated heat.

Not long after the fairing was opened, the rocket's status data report and new orders came from the control room again.

"The rocket has reached the predetermined orbit, the rocket engine is turned off, and the spacecraft is released."

"The release of the spacecraft is complete,

Close the fairing, adjust the attitude of the rocket, and prepare for returning to the atmosphere.

Be careful not to collide with the just-released spacecraft when adjusting the attitude. "

However, at this time, because the rocket has just flown out of the earth's atmosphere, it is impossible to return to the voyage immediately. Instead, it will not start to decelerate and return to the atmosphere until the rocket has circled the earth and reached a suitable position.

Time passed by, and when almost half an hour passed, the person in charge of the control room also issued a new order.

"The rocket is about to enter the designated return location, so it's best to prepare for the second ignition of the rocket! The output power for fighting is 50%."

"30.29.28...3.2.1 Ignition!" Following the order of the person in charge of the launch, the rocket's engine was successfully ignited again, and the flight rules of the rocket in the control room changed. Finally, when the rocket returned When the trajectory overlapped with the launch pad of Tiangong Technology, the person in charge directly issued an order to turn off the rocket engine again.

At the same time, the camera installed on the rocket also faithfully recorded the changes of the rocket's flight attitude and flight rules at this time.

Different from general recoverable rockets when they return to the atmosphere, generally recoverable rockets return to the atmosphere in an upright state when returning to the atmosphere, but this time the rocket returns directly with the head of the rocket facing the atmosphere .

After all, this rocket not only did not abandon the fairing, but even has an aerodynamic rudder on the rocket, which can completely glide and fly in the atmosphere and adjust its attitude.

At the same time, the rocket control center at this time is also doing its best to collect all the data when the rocket returns to the atmosphere.

After the data is collected, it will also be retained, which can provide real and effective data support for the larger recoverable rockets and even aerospace vehicles designed by Wang Bin and Tiangong Technology in the future.

Of course, these data are not only used by Tiangong Technology itself, but can even be used as data support when officials and other companies want to use them. After all, Huaxia is different from foreign countries, especially in aerospace. If so, these data will not be used unconditionally by any domestic official or enterprise, but will be provided for a fee.

As the rocket finally entered the atmosphere, the fairing of the rocket also began to have a huge friction with the high-altitude atmosphere, and the entire fairing began to turn red. According to the sensors inside the rocket fairing, the maximum surface temperature of the fairing had already reached It reached more than 2,000 degrees, and with the temperature inside the fairing, it also began to rise rapidly.

However, although the simplified body and other parts of the rocket are also in friction with the atmosphere at this time, the temperature begins to rise, but the temperature does not rise to 2,000 degrees like the fairing, but only a few hundred degrees.

And at this time, the speed of the rocket, also under the friction with the atmosphere, began to drop sharply. From a speed of about 2,000 meters, it quickly dropped to below 1,500 meters per second, and this speed is still Rapid descent.

When the rocket reaches the middle layer of the atmosphere, the speed of the rocket is only about Mach 3, and the aerodynamic rudder of the rocket can already work, that is to say At this time, the ground can finally control the rocket through the aerodynamic rudder again.

This made everyone breathe a sigh of relief. After all, before the rocket entered the escape layer, because the rocket's engine was not working, it was in a powerless situation, and because the atmosphere in the escape layer was very thin, the aerodynamic rudder It can't produce any effect at all, so at this time, it is the time when the rocket is most likely to lose, and even if it can be controlled, at any time because the speed of the rocket is too fast, when it must be controlled, if the rocket's flying attitude is wrong, it is easy to cause the rocket to lose weight. disintegration.

Now, the rocket has returned to a controllable range. For the ground personnel, the most difficult time has passed, and they are naturally more confident in successfully recovering the rocket.

With the control of the controller, the rocket soon reached the sky above the Tiangong Technology launch site. At this time, the person in charge gave another big order, and the rocket's fairing was slowly opened a little bit again. All of a sudden, the rocket's head As the external resistance becomes larger, the rocket also suddenly changes its flight attitude, and becomes a tail-down attitude again, and as the fairing continues to open, the air resistance of the rocket also becomes greater, and the rocket’s descending speed, Also naturally slower.

And when the rocket is only about a kilometer from the ground, the parachute inside the rocket fairing is also opened, and the rocket's descent speed is quickly reduced to only a few tens of seconds per second.

Finally, when the rocket was less than 100 meters away from the ground, the rocket's engine was ignited again. When the rocket's descent speed became zero, the rocket just stopped steadily at the predetermined parking point, and At this time, the fuel of the rocket has also been exhausted.

In other words, with the smooth landing of the rocket, it means that this launch has also been successfully completed.
