Military Technology

　　 If there is no such buffer, there will still be a relatively large vibration after the return cabin lands. This will cause certain damage to the structure of the return cabin and the internal precision components.

　　 As a result, it will affect the secondary use of the return cabin and increase related maintenance costs.

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

　　 They generally do not have the physical fitness of astronauts, nor have they received relevant training. Therefore, if the return cabin lands on a large impact or vibration, it is likely to cause certain damage to the passengers.

　　 As for the cushioning air cushion, it can play a very good cushioning effect after the return cabin has landed, so that neither the return cabin nor the members in the cabin will be affected too much.

　　 In addition, there is a parachute group composed of three main parachutes, which must be quickly disconnected after the return cabin has landed. To prevent the impact of ground wind, causing the parachute group to drag the return cabin away.

　　 As the height of the return cabin gets lower and lower, the picture on the big screen has also switched from the optical tracking observation device to the angle of view on the drone.

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

　　 "Five hundred meters!"

　　 Following the announcement on the radio, everyone who was still communicating in a low voice stopped hearing the sound. Then 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 was about six to seven hundred meters away from them. Standing on this observation platform on the hillside, everyone can clearly see the three large parachutes and the return capsule hanging under the umbrella.

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

　　 The search and recovery convoy on the ground has also rushed over, and is staring at it from a distance, waiting for the return cabin to land immediately to the scene.

　　 "One hundred meters!"

　　 With this announcement, everyone's heart was suspended again. Everyone is no longer satisfied with staring at the big screen, but staring at the big screen while holding a telescope to watch the scene.

　　 "This is more stressful than I am participating in a fighter's live ammunition shooting." 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 sprayed from the rear of the return cabin, which is the successful ignition of the reverse thrust engine.

　　 Papa Papa...

　　 There was a warm applause at the scene, and some people could not help but cheered.

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

　　 The convoy that had circled around the periphery quickly changed direction and rushed over there. One of their important tasks in such anxious rush was to prevent the main parachute from being disconnected and separated in time, causing the return cabin to be towed away.

Zhou Xiangming and Guo Yulong over there came over with a look of joy. Zhou Xiangming excitedly said at Wu Hao: "The data shows that the 5000-meter airdrop experiment of the manned spacecraft's return capsule was a complete success. Landing safely."

"Great!"

　　 Papa Papa...

　　 The applause rang enthusiastically again.

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

　　Looking at the people eager to try, Wu Hao waved and smiled and said: "Let's go, let's go to the scene."

　　 Immediately surrounded by everyone, Wu Hao and the others boarded the off-road vehicle, and then galloped towards the landing point of the return cabin.

　　Wait until Wu Hao and the others felt that the cleaning of the scene had come to an end.

　　 I saw that the return capsule has landed steadily on the ground, and the orange-red airbag below has also been deployed normally. The main umbrella has separated and fell to the ground.

　　 At this moment, the staff are doing relevant sorting.

　　 The area around the return module 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 is also the first time everyone has seen the true face of Lushan in the return cabin.

　　 The entire surface of the return cabin was painted white, and then a few very thin black lines formed by gaps divided the surface of the return cabin into neat areas.

　　 These white colors are the heat insulation materials on the return cabin, so that when the return cabin re-enters the atmosphere, it prevents the return cabin from being burned by dense atmospheric friction.

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

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

　　 There is a circular hanging window on each side of the return capsule to facilitate the astronauts and passengers inside to observe the outside situation.

　　 Guo Yulong looked at it carefully for a while, then turned his head to Wu Hao and they happily said: "Now we can announce that our manned spacecraft's 5,000-meter airdrop experiment was a complete success."

"Great!"

　　 Papa Papa...

　　 The applause immediately rang, and Yang Fan looked at the busy people and asked, "Will you not open a position on the spot?"

　　 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 when it is shipped back."

　　 "Well, it seems that we all don't look like we return to the cabin." Wu Hao laughed and joked.

　　 Hearing Wu Hao's words, everyone at UU Read www.uukアnshu.com laughed.

　　, accompanied by Zhou Xiangming, said immediately: "There are two more return cabins like this. If you want to see it, you can see it when you return to the base."

　　 In response, Wu Hao smiled and waved his hand: "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 smiled and asked, "So now, is the entire experimental project over?"

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

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

　　 This process usually lasts for a while, but 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 smiled and nodded, then waved his hands at the crowd: "Now that we have a feast for our eyes, let's withdraw, don't affect their normal work.

　　 Although we don’t say anything here, they still have a lot of psychological burden. Let’s go! "
