Chapter 1513 Painting
“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.
Astronaut Body The data detection report has been updated. I am in good health and there are no major problem feedbacks.”
When the report from the public channel was relayed and played in the command center lobby.
On the large screen in the command center, there is a display interface fixed to the return capsule astronaut Zhou Jianwen.
Bang bang bang...
Warm applause sounded, although the applause was only short-lived, and then the staff immediately got back to work.
But all the staff knew clearly that as long as the parachute groups were deployed normally and the power engine array system was turned on normally, the return capsule's landing speed slowed down again and again, and the astronauts' real-time body data did not appear. What a big problem, it 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 things."
"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!"
In the fourth notification At the landing site, 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 of the large screen of the Kyushu Southwest Launch Command Center switched to a Footage 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 taken during long-distance video shooting, 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 main landing parachute adopts a two-stage inflation method, opening a small opening first, 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 after the parachute starts working, and then reduce to 8 meters/second - 10 meters/second. Second.
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 gives A solution was found, which is to ignite the four reverse thrust rockets installed at the bottom of the return capsule when it is about two meters above the ground, so that the speed of the return capsule is reduced to less than 2 meters/second.
This will allow astronauts to land safely on the ground.
It's just that this is a plan that takes more than ten hours to 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. It is 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 power of the engine is increasing and the seat has been reinforced. Please grit your teeth, close your eyes and take a deep breath]
When he saw this line of text provided by Sinan, Zhou Jianwen immediately gritted his teeth and closed his eyes. Take a deep breath, and then begin to control your breathing rate and organ movements.
To enter the elite astronaut ranks, a set of natural and strong teeth is essential.
The purpose is to avoid a series of chain reactions due to a series of dental and oral problems such as cavities and chipped teeth when astronauts need to grit their teeth in critical moments.
When Zhou Jianwen was getting ready, the space seat he was sitting on also turned on the maximum buffering capacity for rapid landing, and the buffering parts with buffering function began to be upgraded, just to be able 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. It is based on Zhou Jianwen's body shape, bones, vital organs and internal organs. The location is customized.
All this work is for buffering, buffering, and buffering!
The human body has great limitations after all.
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 again and again.
Due to the four key reasons of high air flow, air friction, parachute assembly 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 reported below: 102°xx′ east longitude, 31°xx north latitude.”
With the accuracy of the coordinates officially reported this time, Jiuzhou Aerospace Security The teams 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 safety protection circle after another. No unauthorized or unregistered equipment or personnel are allowed. Enter their area of responsibility.
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.
Like an oval-shaped dome, protected by a bunch of black dots, it slowly descends to the ground of Blue Star.
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.
