Chapter One Thousand Two Hundred and Sixty Three: Manned Spacecraft Zero Altitude Escape Device Ignition Experiment
Have you conducted experiments on spacecraft escape devices and how did they perform?
Wu Hao couldn't help but become concerned. After all, this was the last line of insurance related to the safety of astronauts. If something went wrong and the rocket malfunctioned, the escape device would need to function.
But if the escape device also fails, the astronauts inside the spacecraft will really be doomed.
This is a matter of life and death, so Wu Hao naturally takes it very seriously.
Hearing Wu Hao's question, Zhou Xiangming nodded, and then said to Wu Hao: "We have conducted a zero-altitude escape device ignition experiment, and this experiment was a complete success.
Regarding the specific situation, I would like to ask Chief Engineer Guo Yulong, the person in charge of our manned spacecraft project, to introduce it to you in detail."
Wu Hao nodded when he heard this, and then looked at Guo Yulong.
Guo Yulong had obviously made relevant preparations. Seeing Zhou Xiangming mention his name, he immediately opened the folder, nodded to Wu Hao and said.
"On the 10th of last month, we successfully conducted a zero-altitude escape experiment for the spacecraft's return capsule. The experiment simulated a serious failure of the launch vehicle after the spacecraft was launched, in order to ensure the safety of the astronauts.
The command center decisively issued the escape command remotely, and then the reverse thrust rocket on the return capsule of our manned spacecraft quickly ignited and accelerated the return capsule carrying the astronauts away from the faulty rocket and pushed it up to about 1.5 kilometers from the ground.
of high altitude.
Immediately, the guide parachute on the return capsule was thrown out, and the three main parachutes were immediately pulled out, causing the return capsule to quickly decelerate and then land smoothly on the ground. Before landing on the ground, the spacecraft return capsule will start again at a position five meters above the ground.
The reverse thrust rocket further decelerates the return capsule, ensuring that the return capsule can land at the minimum speed and ensuring the personal safety of the astronauts inside the return capsule."
Speaking of this, Guo Yulong said to Wu Hao: "We have recorded the entire experimental process with relevant videos and photos. We have produced a short video of more than one minute, you can take a look."
Haha, it seems that you are already prepared. Wu Hao then nodded and agreed.
At Guo Yulong's signal, the lights in the conference room dimmed, and on the large high-definition screen on one side, videos and photos related to the experiment mentioned by Guo Yulong began to play.
The video begins with a few photos of the scene. It can be seen that a manned aircraft is placed in the experimental site. To be honest, this is the first time for Wu Hao to see the full picture of their own manned aircraft.
As a reference to the people on site, this manned ship appears to be very tall.
After a few photos, the launch process began. Following several thick and powerful countdowns, fire and huge smoke and dust erupted from the bottom of the manned spacecraft's return capsule.
Whoosh...
With a huge roar, long orange-red flames erupted from the tail around the return capsule, quickly pushing the spacecraft's return capsule high into the sky.
The return capsule of the spacecraft flew higher and higher, getting smaller and smaller. Then the screen switched to the optical tracking device. Through the optical tracking device screen, you can see that the return capsule was pushed to an altitude of about 1.5 kilometers above the ground, and then began to fall.
Not long after the fall, the guidance parachute on the spacecraft's return capsule was thrown out, and then the three main parachutes were also ran out and unfolded, and the speed of the spacecraft dropped significantly.
The scene turned to the scene of the spacecraft landing on the ground. With a burst of huge smoke and dust, the spacecraft was covered by the smoke and dust, and the three huge parachutes immediately detached and slowly fell to the ground.
The video ends, followed by some photos from the scene.
Guo Yulong introduced to Wu Hao and the others: "Everyone, please take a look, this is a photo of the spacecraft after landing. We can see that the surface is very complete, and there is no loss. And the posture is upward. It can be said that the entire landing process is very smooth."
Perfect.
This is what we said when we transported the return capsule of the spacecraft back to the research institute. We can see that everything is normal inside the return capsule. The seven dummies we used for experiments did not have any damage. The various experimental sensors on the dummies were not damaged.
Everything is normal too.
This shows that this experiment was also a complete success, and our idea of using the spacecraft's recoil engine as an escape device is correct."
Bang bang bang bang...
Wu Hao took the lead, and warm applause broke out in the conference room.
Well done! Wu Hao praised, and then asked Guo Yulong: "I noticed that your manned spacecraft's zero-altitude escape experiment was conducted using the relaxation of orders issued by the command and control center.
So is this method also used in real launch missions, what are the judgment criteria, and is it reliable?"
Hearing Wu Hao's question, Guo Yulong nodded and explained: "That's it, we have set up a total of three methods for the activation of the escape device. Any of these three methods can return the manned spacecraft to the cabin.
Take away the malfunctioning rocket, allowing the astronauts in the return capsule to escape safely.
First of all, the first method, which is also the most commonly used method, is to let the intelligent systems of the rocket and spacecraft make independent judgments and activate the escape device independently.
If the rocket's intelligent control system determines that there is a problem with the rocket, the rocket's intelligent control system will transmit the relevant alarm to the spacecraft's intelligent control system, and then the spacecraft will make an emergency response and activate the escape device.
The entire reaction time is very short, usually only a few seconds or even a few milliseconds. It can be said to be very sensitive and fast, which is helpful for the spacecraft to deal with major accidents that may occur and ensure the safety of astronauts.
The second method is for the astronauts carried in the return capsule of the manned spacecraft to manually control the escape.
This method occurs when the rocket's intelligent control system or the spacecraft's intelligent control system fails and cannot respond accordingly in time.
At this time, the astronauts inside the spacecraft detected the relevant data, and immediately followed the relevant procedures to manually activate the escape system.
The escape device on the spacecraft's return capsule will also respond quickly, pushing the return capsule to escape to a safe distance before landing.
This third method is naturally to be remotely controlled by our ground command and control center. This situation occurs when the intelligent control systems of the rocket and spacecraft fail, and the astronauts in the manned spacecraft return capsule do not find the failure, or in other words, the astronauts
The operator is incapacitated, such as comatose, or injured and in critical condition, and cannot manually activate the escape system.
At this time, the ground measurement and control center, which has been paying close attention to the rocket's flight situation on the ground, will immediately report to the command and control center after detecting a rocket failure. The command and control center will also respond immediately and remotely control the spacecraft to detach from the faulty rocket, thus safely
