Military Technology

Without this buffer, there will still be relatively large vibrations after the return capsule lands. This will cause certain damage to the structure of the return capsule and the precision components inside.

As a result, the secondary use of the return capsule will be affected and related maintenance costs will be increased.

On the other hand, this vibration will also cause certain damage to the astronauts and passengers in the cabin. Especially for some passengers who will take the reentry capsule in the future.

They generally do not have as good physical fitness as astronauts, nor have they received relevant training. Therefore, if there is a large impact and vibration on the landing of the return capsule, it is likely to cause certain injuries to passengers.

As for the cushioning air cushion, it can play a very good cushioning effect after the return capsule lands, so that neither the return capsule nor the members in the cabin will be greatly affected.

In addition, there is also a parachute group composed of three main parachutes, which must be disconnected quickly after the return capsule lands. Prevent being affected by the ground wind, thereby causing the situation that the parachute group drags the return capsule away.

As the altitude of the return capsule became lower and lower, the picture on the big screen also switched from the optical tracking observation equipment to the perspective of the drone.

Through the perspective of the drone, everyone can see the status of the entire return capsule landing process very clearly at close range.

"Five hundred meters!"

Following the broadcast on the radio, everyone who was still whispering stopped hearing the sound. Then he either stared at the big screen intently, or picked up the binoculars and looked carefully.

"Three hundred meters!"

The landing point of the return capsule is about six or seven hundred meters away from them. Standing on the observation platform on the hillside, everyone can clearly see three large parachutes and the return capsule hanging under the umbrella.

Although it was morning and the sky was bright, the alternating red and blue warning lights on the return capsule were still very conspicuous.

The search and recovery convoy on the ground has also rushed over, and is staring at it from afar, waiting for the return capsule to land and immediately arrive at the scene

"One hundred meters!"

With this announcement, everyone's let go of their hearts hung up again. Everyone is no longer satisfied with staring at the big screen, but staring at the big screen while watching the scene with a telescope.

"It's more nervous than me participating in live-fire target shooting by fighter jets." Director Tian couldn't help but said with a smile. Even so, his fists clenched without knowing when.

rumbling...

I saw flames and a large amount of white smoke suddenly ejected from the tail of the return capsule, which indicated that the thrust reverser engine had successfully ignited.

clap clap clap...

Immediately there was warm applause at the scene, and some people couldn't help cheering.

The smoke sprayed by the thrust reverser engine and the dust blown up from the ground also quickly enveloped the return capsule and disappeared from everyone's sight.

The convoy that had been circling around for a long time quickly changed direction and rushed over there. An important task for them to rush over in such a hurry is to prevent the main parachute from being disconnected in time, causing the return capsule to be towed away.

Zhou Xiangming and Guo Yulong over there walked over happily, and Zhou Xiangming excitedly said to Wu Hao: "The data shows that

The 5,000-meter airdrop experiment of the return capsule of the manned spacecraft was a complete success, and the return capsule landed safely. "

"it is good!"

clap clap clap...

The applause rang out again.

Wu Hao couldn't help but smile when he heard Zhou Xiangming's words, and he finally breathed a sigh of relief.

Looking at the eager crowd, Wu Hao waved his hands and said with a smile, "Let's go, let's go and see the scene."

Immediately surrounded by the crowd, Wu Hao and the others boarded the off-road vehicle, and then sped away to the landing point of the return capsule.

When Wu Hao and the others felt that the cleaning work on the scene had come to an end.

I saw that the return capsule had landed steadily on the ground, and the orange-red airbag below had also deployed normally. The main parachute has detached and is floating on the ground.

At the moment, the staff are sorting out the relevant work.

The return capsule was also cordoned off by the search and recovery team, and security personnel were also on duty at the four corners.

The people who got out of the car quickly came to the cordon. It was also the first time that everyone saw the true face of Mount Lu in the return capsule.

The entire surface of the return capsule is painted white, and then the black lines formed by several very thin gaps divide the surface of the return capsule into some neat areas.

These whites are the heat insulation material on the return capsule, so that when the return capsule re-enters the atmosphere, it will prevent the return capsule from being burned by the friction of the dense atmosphere.

These insulating materials can be replaced to facilitate secondary use. In principle, this return capsule can be used repeatedly, thereby reducing the cost of a single flight of a manned spacecraft.

Of course, if the return capsule is damaged during the return and landing process, it cannot be used again for safety reasons.

There is a circular hanging window on both sides of the return capsule, so that the astronauts and passengers inside can observe the outside situation.

Guo Yulong looked at it carefully for a while, then turned to Wu Hao and the others and said happily, "Now we can announce that our 5,000-meter airdrop experiment of the manned spaceship return module has been a complete success."

"it is good!"

clap clap clap...

Immediately the applause rang out, and Yang Fan looked at the busy crowd and couldn't help asking: "Aren't you going to open a position at the scene?"

Guo Yulong shook his head: "No, the site environment is relatively poor, so for the safety of the instruments and equipment inside, it will not be opened for the time being, and the warehouse will be opened in the laboratory after it is transported back."

"Well, it seems that we all don't have the look of returning to the capsule with a feast of eyes." Wu Hao joked with a smile.

Hearing Wu Hao's words, everyone laughed.

Zhou Xiangming, who was accompanying him, said immediately: "There are two more return capsules like this. If you want to see them, you can see them when you return to the base."

Regarding this, Wu Hao waved his hand with a smile and said, "Forget it, I won't affect everyone's work."

Speaking of this, Wu Hao looked at the trailer that was already directing the approach, and then asked with a smile: "So now, is the whole experimental project over?"

Guo Yulong nodded and said: "Yes, today's return capsule airdrop experiment is considered a complete success. However, this does not mean that the entire airdrop experiment is complete. In fact, we have to carry out multiple return capsules at multiple heights. Airdrop experiment.

To verify the reliability of the technology and equipment operated on the return capsule, as well as the flight attitude at different altitudes, etc.

This process usually lasts for a period of time, however, this will not affect the progress of other projects, nor will it affect the launch of our first unmanned experimental spacecraft early next year. "

"Okay." Wu Hao nodded with a smile, then waved his hands at the crowd and said, "Now that we have feasted our eyes, let's withdraw, so as not to affect their normal work.

Although we don't say anything here, it still has a lot of psychological burden for them, let's go! "
