Chapter 1110 Space Suit
It is said that they are not afraid of taking risks, even if they throw their heads and blood for the aerospace industry of the motherland, they will not hesitate.
But after Zhao Zhongyao heard what they said, he smiled and said: "This is not something you can do if you want to. Now, you still have nine astronauts who have not carried out the flying experiment! This time you need two astronauts. But I can't say who can and who can't! To be fair, I think it's better to come to an assessment competition."
When Zhao Zhongyao said this, the other astronauts naturally couldn't compete anymore. After all, Zhao Zhongyao's statement is very fair. In such a competition, whoever has the best grades will go. Isn't this a bowl of water?
Although Zhao Zhongyao also wanted Zhai Fanggang and Jing Tianpeng to conduct this manned spaceflight experiment, he couldn't just say that! Otherwise, other astronauts would definitely feel that Zhao Zhongyao is facing these two guys!
Because of this, Zhao Zhongyao also called Zhai Fanggang and Jing Tianpeng to his office before assessing everyone.
Zhao Zhongyao looked at the two of them and said: "Actually, this time, I want you two to conduct this manned spaceflight experiment. But I can't let you two go directly. Other astronauts are also looking at me I can only conduct another assessment for you. I hope that you two will work harder and be able to rely on your own strength to get the space experiment quota."
After hearing Zhao Zhongyao's words, Zhai Fanggang and Jing Tianpeng said in unison: "Don't worry! Mr. Zhao, the two of us will definitely defeat them."
"Okay, that's it. You two get ready. We will start the astronaut selection assessment tomorrow." Zhao Zhongyao said again.
"Okay, we know." The two said together again.
In this way, Zhao Zhongyao conducted another assessment of the nine astronauts. The content of the assessment is similar to that of the previous training team, that is, the theoretical assessment must be conducted first, and then the physical fitness assessment.
The results of the final assessment really satisfied Zhao Zhongyao. Zhai Fanggang and Jing Tianpeng won the first and second place respectively, beating the other seven astronauts. The two of them finally got the places for the next space trip.
Seeing such results, Zhao Zhongyao also praised Zhai Fanggang and Jing Tianpeng a few more words.
"Okay, you two have lived up to my expectations of you and won the first and second place." Let me praise you first.
Zhai Fanggang and Jing Tianpeng were also very happy after hearing Zhao Zhongyao's words. The two laughed together.
"However, then again. It is naturally not easy to be selected as an astronaut. But the training you will face next is even more difficult.
This time, the task you have to face is even more important than Yang Chengwei's last task! Last time, Yang Chengwei just stayed in the space capsule. until he fell from the sky. Didn't get out of that capsule at all.
But this time, it's different. You are on a spacewalk mission. Go to space to experience what kind of environment outer space is like.
So, the training task you two will accept next is also a training task, and it is also very hard. I don't know, whether you two are willing to accept it or not. If the two of you feel that you don't want to suffer and accept this spacewalk mission, then I can also change two more astronauts. "
Before Zhao Zhongyao formally trained Zhai Fanggang and Jing Tianpeng, he also had to say something up front so that they could be prepared.
"Mr. Zhao, don't worry! We will definitely be able to complete the training mission. We are all soldiers, so how can we be afraid of hardship and tiredness!" Zhai Fanggang looked at Zhao Zhongyao and said.
"Yes! Mr. Zhao, we will never be afraid of hardship or tiredness, we can endure hardship. You just need to train us." Jing Tianpeng said the same.
"Okay, then from tomorrow, you guys will start to receive closed training! The training time is half a year. After half a year, we will conduct the second manned spaceflight experiment. You two must make a mental preparation first." Zhao Zhong Haru said so again.
"Yes, everything is under Mr. Zhao's command." Zhai Fanggang and Jing Tianpeng were also very happy after hearing Zhao Zhongyao's words. Just thinking, I am about to become a real astronaut.
That night, Yang Chengwei also came to the dormitory of Zhai Fanggang and Jing Tianpeng, and chatted with them about the next manned space mission.
"Congratulations to you two, you finally have the opportunity to travel in space." Yang Chengwei said as soon as he arrived at Zhai Fanggang and Jing Tianpeng's dormitory.
"Hey, Cheng Wei, what does it feel like to be in the sky! Are you scared?" Zhai Fanggang looked at Yang Chengwei and asked.
"Yes! Cheng Wei, the last time you went to the sky, I heard that you heard some knocking sound in the middle of the night. What's going on? How could someone knock on the door in space!" Of course, Jing Tianpeng also heard about the strange knocking sound that Yang Chengwei heard in space. He still doesn't understand what's going on!
Now Yang Chengwei pretended to be mysterious and said: "Hey, it's really scary to say it! At that time, I thought it was haunted! I thought, there are ghosts in this space! How could it be in the middle of the night? The thing about the ghost knocking on the door. Speaking of it, I was really a little scared. But fortunately, there is no major problem. Thinking about it, it is not a serious matter."
"Hey, what is the reason!" Zhai Fanggang and Jing Tianpeng arrived at the scene
Now, I still don't know what caused the knocking sound.
After the space mission is completed this time, the knocking sound is of course an internal matter. It was not made public. After all, in this case, it will affect the mood of other astronauts in the future. It's better not to make this matter public.
However, Zhai Fanggang and Jing Tianpeng are none other than Yang Chengwei's good friends, of course he can talk about this matter with these two friends.
Yang Chengwei almost knew what was going on by now. Of course, he couldn't be sure. After all, Zhao Zhongyao said it, and what he said was just speculation. Before actually seeing those so-called small celestial bodies, no one could prove that the knocking sound that Yang Chengwei heard that night was caused by the impact of these small celestial bodies.
"I have already studied this issue with Mr. Zhao and Dean Cheng. Mr. Zhao speculates that it may be caused by small celestial bodies in space. He said that there are also some very small space particles in space. These things in space The random flight in the air is like bullets. In fact, their speed is much faster than the bullets.
When these small celestial particles come into contact with the space capsule, of course they can cause certain harm to the space capsule. However, these small celestial particles are very small, about the same as bullets. Such a small celestial particle, even if it hits the space capsule, it is impossible to cause much damage to the space capsule.
But for the astronauts in the space capsule, there will definitely be some frights. The knocking sound I heard that night may have been caused by these small objects hitting the hatch of the space capsule.
But Mr. Zhao said that all this is just his speculation. Whether this is the case, he is not sure. One of your flying missions this time is to find out what was the reason for that weird knocking sound last time. "
Yang Chengwei told Zhai Fanggang and Jing Tianpeng what he had heard from Zhao Zhongyao.
After the two listened, they felt that it made sense. It is very likely that some small celestial body particles hit the hatch of the space capsule, and then Yang Chengwei inside heard a strange knock on the door.
However, no one is sure about this now. Only when Zhai Fanggang and Jing Tianpeng fly to the sky, can this unsolved mystery be solved.
"Cheng Wei, don't worry! After the two of us fly for nine days this time, you will definitely catch that 'ghost'. Then, you have to teach it a good lesson." Zhai Fanggang looked at Yang Chengwei again. made a joke.
"That's right, Cheng Wei. This time, the two of us flew together for nine days. No matter what happens, there will be someone to take care of us. We will definitely catch the culprit who scared you." Jing Tianpeng Hearing Zhai Fanggang's words, he also echoed this sentence.
"Haha, okay, then I'll leave it to you two." Yang Chengwei also laughed.
Besides, Zhao Zhongyao's current work is also very tense. On the one hand, he wants to conduct training camps for Zhai Fanggang and Jing Tianpeng. On the one hand, we have to quickly design a new spacesuit! After all, the space suit designed for Yang Chengwei last time could not meet the needs of this space mission. He now has to design a new spacesuit.
Space suits are personal airtight equipment that guarantee the life activities and work capabilities of astronauts. It can protect the human body from environmental factors such as vacuum, high and low temperature, solar radiation and micro meteors in the space. In a vacuum environment, the nitrogen contained in human blood will turn into gas, causing the volume to expand. If a person does not wear a pressurized and airtight spacesuit, his life will be in danger due to the great difference in pressure between the inside and outside.
The spacesuit is a multifunctional clothing developed on the basis of the airtight suit of the pilot. Early space suits could only be used by astronauts in the cockpit of the spacecraft, and space suits for extravehicular use were developed later. Modern new space suits for extravehicular use have a liquid-cooled cooling structure, which can be used by astronauts to carry out activities outside the space capsule.
In addition to the various layers of the astronauts' structure used in the cabin, the space suit used outside the cabin has three layers: one is the vacuum insulation layer, which is used to protect the astronauts from working outside the cabin or on the surface of the moon and other stars. It is attacked by the overheated and overcooled environment outside the cabin, and it can also prevent the heat loss inside the clothing. The second is the liquid-cooled suit, which is formed by changing the gas in the ventilation and heat dissipation layer tube of the space suit in the cabin into liquid.
Astronauts work outside the cabin for several hours sometimes, and the body generates a lot of heat, which cannot meet the heat dissipation requirements by gas heat dissipation, but the liquid cooling medium can dissipate the heat well. The third is the outermost layer. In addition to the functions of anti-high heat, anti-wear and protection of the inner layers, it also has the function of anti-solar radiation and the interface connected to other equipment.
For example, it is connected with the umbilical cord of the astronauts during extravehicular activities, the connection with the portable life protection environmental equipment, the space maneuvering flight mechanism, etc. The helmet of the space suit is composed of components such as the helmet shell, the window structure and the neck ring.
There are two kinds of helmets used in manned spaceflight: soft and hard, and the hard helmets are divided into two types: fixed and rotating. Soft helmets are mostly used as components of cabin spacesuits. Rotary helmets have airtight movable bearings on their neck rings, but increasing the number of sealing links will reduce airtightness and structural reliability, and increase design difficulty.
Zhao Zhongyao also knew something about the design characteristics of the extravehicular spacesuit before his death. Now for him, he only needs to design the structure of the space suit he knows.
In this way, in the past six months, Zhao Zhongyao started to develop a new generation of spacesuits for extravehicular use while training Zhai Fanggang and Jing Tianpeng.
Fortunately, everything went smoothly. Half a year later, both jobs are almost complete.
Of course, other scientific researchers are not idle either, they have developed a space capsule and a flight capsule. This space mission and
It was different last time. This time, the astronauts not only need to stay in the space capsule, but also go out of the space capsule!
The return capsule is obviously not suitable for out-of-cabin activities. To allow astronauts to move out of the cabin, it is necessary to design a new flight cabin. Let this flight capsule be connected with the space capsule for return.
First use the rocket to launch the space capsule and the flight capsule into space together. Then, let the capsule and the flight capsule fly in space together. The astronauts can stay in the space capsule first. When it's time to perform the mission, they come out of the space capsule and then enter the flight capsule.
In the flight cabin, the astronauts have to complete the activities outside the cabin. After they finish the task. They then return to the ground in a space capsule. And the flight capsule remained in space.
In the past six months, Zhao Zhongyao is also very busy. On the one hand, he has to train Zhai Fanggang and Jing Tianpeng. On the one hand, it is necessary to design and develop new space suits. It is also necessary to successfully help Cheng Yu and the others to develop the space capsule and flight capsule used in the second spaceflight.
Although the reentry capsule used by Yang Chengwei last time has already been recovered. And it still looks good. Manned spaceflight is a high-risk job. No problem at all. It is something that needs to be 100% successful.
Therefore, even if it is the space capsule recovered last time, there is no big problem. But when new spaceflight experiments are to be carried out, the previous space capsules will no longer be used. Need to develop a kind of space capsule again. Only in this way can the safety of astronauts be fully guaranteed.
