Technology: breaking the hegemony that monopolizes the world

"The Titan Radar Department reported that the return capsule parachute groups were successfully deployed, the power engine array system was turned on normally, and Sinan has been connected to the Blue Star LAN.

The astronaut's physical data test report has been updated. He is in good health and has no major problem feedback. "

When the public channel report is relayed and played in the command center lobby.

On the large screen in the command center, a display interface was fixed to the return capsule astronaut Zhou Jianwen.

Bang bang bang...

Warm applause broke out, although the applause was only short-lived, and then the staff immediately got back to work.

But all the staff members clearly know that as long as the parachute groups are deployed normally, the power engine array system is turned on normally, and the landing speed of the return capsule slows down, and there are no major problems with the astronauts' real-time body data, then This means that this 4-hour extreme return home mission has been 90% successful!

As long as the return capsule can successfully slow down its landing speed to normal in the last few kilometers and successfully land in the predicted area, then this extreme return home mission can be declared a great success!

At this time, in some small channels of the project team, managers were already telling them: "Be calm when encountering big problems."

"Stand guard until the last second. Don't take it lightly. While the medical team pays attention to the astronaut's physical condition, they must also pay close attention to the astronaut's complexion, pupils, breathing and other appearances. The sensing equipment may malfunction, but the body organs will not!"

When the landing site was reported for the fourth time, a space security team suddenly reported back: "The Albatross drone has discovered the return capsule! The real-time video has been uploaded!"

Soon, the main screen on the big screen of the Kyushu Southwest Launch Command Center switched to a picture of the return capsule landing captured by a drone.

In the high-definition video, the return capsule with many other colors on the outer shell is slowly descending with the support of the parachute group and power engine.

It's just that this was shot in a long-distance video, and the descent speed appears to be slow. But as long as you look at the actual descent speed next to the screen, you can clearly know that the landing speed of the return capsule this time is still very fast.

100 meters/second!

When the deceleration parachute is working, the landing main parachute adopts a two-stage inflation method, first opening a small opening, and then slowly opening it fully.

In mainstream international use, the descent speed of the return capsule will gradually decrease from 80 meters/second to 40 meters/second, and then to 8-10 meters/second after the parachute starts working.

But even if it lands at a speed of 8 meters/second, the impact force of the return capsule may still cause damage to the astronaut's spine and brain. Therefore, the landing plan provided by Daxia Aerospace Group provides a solution. When it is about two meters above the ground, the four reverse thrust rockets installed at the bottom of the return capsule perform ignition, reducing the speed of the return capsule to less than 2 meters/second.

This allows astronauts to land safely on the ground.

It's just that this is a plan that takes more than ten hours to land and land. Daxia Aerospace Group has no reservations about Jiuzhou Technology's safety settings, and even provides technical support channels for induction equipment and ignition equipment.

It's just that after Gu Qing entered the Jiuzhou Aerospace Department, the style of the Jiuzhou Aerospace Department has long been no longer down-to-earth and progressive.

The four-hour extremely fast landing plan is not generally radical. Reflected in reality, even the conventional landing deceleration plan combined with more advanced special materials and equipment can only control the speed at 100 meters/second!

There is a huge gap from the current stage 40/second data given by Daxia Aerospace Group.

"It has landed at the predetermined height, and the power of the power engine will be gradually increased."

It was just a warning, but to Zhou Jianwen inside the return capsule, it seemed like a line of text.

[The engine power is increasing and the seats have been reinforced. Please grit your teeth, close your eyes and take a deep breath]

When he saw this line of text provided by Simon, Zhou Jianwen immediately gritted his teeth, closed his eyes and took a deep breath, and then began to control his breathing rate and organ movements.

To enter the ranks of elite astronauts, a set of naturally strong teeth is essential.

This is because when astronauts need to grit their teeth in critical moments, a series of chain reactions will not occur due to a series of dental and oral problems such as cavities and chipped teeth.

When Zhou Jianwen was getting ready, the space seat he was sitting on also opened the maximum buffering capacity for rapid landing, and the buffering parts with buffering function began to be upgraded, just to buffer and absorb the huge energy generated by the impact before landing. .

The seat is custom-made, and the special cushioning cushion between the seat and the astronaut is also made of polymer materials and aerospace materials, and is customized according to Zhou Jianwen's body shape, bones, vital organs and internal organs.

All this work is for buffering, buffering, and buffering!

After all, the human body has great limitations.

While the return capsule is starting a new phase of buffering work, the Kyushu Southwest Launch Command Center is also updating and preciseing the landing area of ​​the return capsule.

Due to the four key reasons of high air flow, air friction, parachute group and power engine, the landing location is always changing. The landing area can only be determined and narrowed step by step with the help of algorithms and radar.

Not long after, without the help of technological products such as drones and radars, the Jiuzhou Aerospace Security Team in the area where the return capsule predicted the landing site could already see with the naked eye a return capsule landing at a high speed.

"Attention all units, the official landing site coordinates will be announced below: 102°xx' east longitude, 31°xx north latitude."

With the coordinates officially reported this time, the Jiuzhou Aerospace Security fleet also started their own actions.

There is no human habitation in the core area of ​​the landing area. UAVs, bionic robots and security personnel from Jiuzhou Technology form one security circle after another, and no unauthorized or unregistered equipment or personnel are allowed to enter the area they are responsible for.

In addition to telemetry equipment, there are also some special weapons and equipment aimed at the marked dangerous areas around them. As soon as an abnormality occurs, a series of plans will immediately become established plans.

As the landing speed of the return capsule became slower and slower, Jiuzhou Technology's drone also began to fly with it.

It was like an oval-shaped dome, guarded by a bunch of black dots, slowly descending to the blue star ground.

Bloomberg squatted next to the temporary command vehicle not far away, watching the giant thing landing in the sky, and his fingers danced wildly on the drawing board.

In the color depiction, a giant object breaks through the sunset curtain when darkness is approaching.
