Xiao Wu, congratulations, congratulations! Wei Hongyu congratulated Wu Hao again. The whole recycling process today gave me a much more intuitive and shocking feeling than when I watched the news before.
No, you've been rewarded. Wu Hao replied with a smile.
Wei Hongyu was about to say something when the radio in the hall rang again.
The helicopter recovery team reported that they had discovered the gliding fairing halves A and B and were preparing to recover them.
Along with the sound, the picture on the big screen showed a blue sky, with two orange-red dots flying in the distance.
Zooming in, the two orange-red dots are actually paragliders on the two halves of the fairing.
As the image of the orange-red paraglider and its two halves of the fairing becomes clearer and larger, even recovery is getting closer.
I saw two domestic medium-sized helicopters with yellow special operation paint that were responsible for recovery tasks and began to maneuver.
For safety reasons, the two halves of the ab fairing are not recycled together. Instead, the a half fairing is recovered first, and then the b half fairing is recovered.
After finding a suitable angle of entry, the helicopter quickly flew towards the A half fairing. The long hook is aimed at the paraglider on the fairing.
The hook hit the paraglider, but due to the helicopter propeller, the parafoil was cheap and the first aerial recovery failed.
However, the helicopter did not give up, but immediately adjusted its attitude accordingly and performed a secondary recovery.
This time, the hook did not hit the paraglider, but used the relaxation of the diagonal fall to hang directly on the parachute rope under the paraglider.
As the helicopter maneuvered and pulled up, with the hook in hand, the parafoil immediately lost its function, and the entire A-half fairing hung directly under the belly of the helicopter.
Immediately, the domestic medium-sized helicopter painted in yellow special operation quickly flew away with the A half fairing, while another domestic medium-sized helicopter painted in yellow special operation also began to recover the B half fairing.
This recovery was very smooth. After only one use, the hook was attached to the parafoil, and the B half fairing was successfully hung on the belly of the helicopter. The recovery was successful.
good!
Bang bang bang bang...
Immediately, cheers and warm applause resounded throughout the hall.
However, everyone did not breathe a sigh of relief, because amidst everyone's applause, another exciting news came out on the radio.
The weapon and arrow separated, and the secondary rocket shut down and separated. "
"The Anxi Satellite Telemetry Center reported that the rocket's second stage separated and is falling towards the predetermined area."
Bang bang bang... At this time, not only the guests observing, but also all the staff in the hall clapped and cheered.
Up to now, the entire launch mission has been successfully completed. Although the specific results have yet to be calculated and confirmed, judging from such a smooth launch process, success is already certain.
After so many years of rocket launches, they actually now have an answer in their minds as to whether the launch mission can be successful. But for the sake of conservatism, everything has to wait for the final confirmation of the results.
On this side, the rocket recovery work is not over yet. The re-entry and fixed-point controlled fall experiments of the second-stage rocket have only now officially begun.
Adjust the flight attitude of the second-stage rocket to target the earth
Posture adjustment in progress!
Through the demonstration animation on the big screen, everyone can also intuitively see the attitude adjustment process of the second-stage rocket.
Attitude adjustment is successful, the main engine ignites in ten seconds, three, two, one, ignition!
Immediately through the camera next to the tail engine of the second-stage rocket, everyone could clearly see particles being ejected. You cannot see the flames in space, but you can see the particles ejected from the combustion, which proves that the rocket has started working.
...Three, two, one, the main engine shuts down, and the second-stage rocket enters the re-entry orbit.
The second-stage rocket glides and unfolds its wings, calculates its re-entry trajectory and estimates its approximate landing point.
The second-stage rocket's gliding wings unfolded, and the first parachute was thrown out.
The ground telemetry team reported that the second-stage rocket has been captured and is being closely tracked.
The first parachute was cut off and the second parachute was thrown out.
The ground measurement and control team reported that the gliding speed of the second-stage rocket body slowed down.
Entering the ionosphere, the signal is interrupted.
The ground measurement and control team reported that the current gliding trajectory of the second-stage rocket body coincides with the estimated trajectory height, and the initial landing point is located fifty kilometers northwest of the landing site, with coordinates east longitude...
…
Now the entire command and control hall is concentrating and watching every data broadcast by the listeners, as well as the colorful pictures and various data information on the big screen.
The second-stage rocket body passed through the ionosphere and communications were restored.
Immediately following this announcement, the picture transmitted by the camera on the secondary rocket body appeared on the screen, although it was very laggy and there was some blurry screen.
But it was also the first time that everyone saw the entire flight attitude and gliding process of the secondary rocket body.
Seeing this scene, many people present couldn't help but think of a very powerful weapon in war, the cruise missile.
At this moment, the posture of the second-stage rocket gliding in the high altitude is a bit like the posture of a cruise missile flying in the air.
It's just that cruise missiles rely on fuel for propulsion, while this two-stage rocket relies on aerodynamics and rudder for control.
Prepare to connect to the second-stage rocket and conduct the first mid-air orbit change.
Started to connect to the second-stage rocket, the connection was successful, and the signal transmission was normal. Immediately, a very clear surveillance picture began to appear on the big screen.
The main engine is ignited and the first attitude adjustment is performed.
Following the relevant instructions, the main engine ignited immediately, and a white trajectory was quickly drawn in the future sky!
The main engine was shut down and the third parachute was thrown out.
The third parachute was successfully thrown.
The ground measurement and control team reported that the flight trajectory of the second-stage rocket body overlaps with the planned trajectory, and the expected landing point is 60 kilometers northeast of the landing site, with coordinates east longitude...
Through the telemetry images sent back by the ground measurement and control team, everyone can clearly see the second-stage rocket body that is gliding and landing in the high altitude at this moment, with a small parachute trailing behind it.
"The ground measurement and control team reported that the flight attitude of the second-stage rocket body was normal, the speed was normal, and it was four thousand meters above the ground. The final landing point was 64 kilometers northeast of the landing site, with coordinates east longitude..."
Turn on the landing site monitoring equipment!
Immediately, the surveillance cameras installed at the landing site and the drone surveillance footage flying in the air were displayed on the screen.
After a quick artificial intelligence search, several images were re-enlarged and appeared on the screen.
In the middle of these pictures, there is a red box that is constantly flashing. Within the box, a white dot is moving rapidly in the air.
