Chapter 1082: Space suit

The first thousand and tenth chapter space suit
It is said that they are not afraid of taking risks. For the aerospace industry of the motherland, even if they shed their heads and blood, that would be no hesitation.
Only after hearing what they said, Zhao Zhongyao smiled and said, "This is not something you are willing to do. Now, you still have nine astronauts who have not conducted flying experiments! This time you need two astronauts. I can’t say who can and who can’t! To be fair, I think it’s better to have an assessment competition."
Zhao Zhongyao said that, the other astronauts, naturally, it is not easy to fight. After all, Zhao Zhongyao's statement is very fair. In such a competition, whoever has good grades will go. Isn't this a bowl of water?
Although Zhao Zhongyao also wanted Zhai Fanggang and Jing Tianpeng to carry out this manned space flight experiment, he couldn't say that directly! Otherwise, other astronauts, then he would definitely feel that Zhao Zhongyao is facing these two guys!
Because of this, Zhao Zhongyao also called Zhai Fanggang and Jing Tianpeng into his office before conducting the assessment.
Zhao Zhongyao looked at them and said, "Actually, this time, I want you two to conduct this manned space experiment. But I can't let you two go directly. Other astronauts are also looking at me. I can only test you again. I hope that you two will work harder and be able to rely on your own strength to get this space experiment quota."
After hearing what Zhao Zhongyao said, Zhai Fanggang and Jing Tianpeng said in unison: "Don't worry! Mr. Zhao, we two can definitely defeat them."
"Okay, that's it, you two prepare, tomorrow we will start the astronaut selection and assessment." Zhao Zhongyao said again.
"Okay, we see." The two said again together.
In this way, Zhao Zhongyao conducted another assessment on the nine astronauts. The content of the assessment is similar to that of the previous training team, that is, the theory assessment must be performed first, and then the physical fitness assessment.
The result of the final assessment really made Zhao Zhongyao satisfied. Zhai Fanggang and Jing Tianpeng beat the other seven astronauts with first and second results respectively. The two of them finally got the quota for the next space expedition.
Seeing such achievements, Zhao Zhongyao also praised Zhai Fanggang and Jing Tianpeng again.
"Well, you two did not live up to my expectations of you, and got the first and second places." I first praised you.
After Zhai Fanggang and Jing Tianpeng heard what Zhao Zhongyao said, they were also very happy. The two just laughed together.
"However, again, it is not easy to be able to select astronauts. 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 time! Last time, Yang Chengwei just stayed in the space capsule. Until he fell from the sky. Did not get out of the space capsule at all.
But this time, it's different. What you are going to perform is a spacewalk mission. Go to space to experience what kind of environment outer space is like.
So, the training task you two have to accept below is also a training task, which is also very hard. I don't know, whether you two are willing to accept it. If you two feel that you don't want to endure this hardship and are unwilling to accept this spacewalk mission, then I can also change two astronauts. "
Before Zhao Zhongyao officially trained Zhai Fanggang and Jing Tianpeng, he also had to put some words to the forefront, so that they had a preparation in their hearts.
"Mr. Zhao, don't worry! We will definitely be able to complete the training mission. We are all soldiers, how can we be afraid of hardship and tiredness!" Zhai Fanggang said while looking at Zhao Zhongyao.
"Yes! Mr. Zhao, we will never be afraid of hardship, we can endure hardship. You just need to train us." Jing Tianpeng also said.
"Okay, from tomorrow, you will begin to receive closed training! The training time is half a year. After half a year, we will conduct the second manned space flight experiment. You two must first have a psychological preparation." Zhao Zhong Haruka said again.
"Yes, everything is under Zhao's command." Zhai Fanggang and Jing Tianpeng were very happy after hearing what Zhao Zhongyao said. 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 both of you, you finally have the opportunity to travel in space." Yang Chengwei said as soon as he arrived at the dormitory of Zhai Fanggang and Jing Tianpeng.
"Hey, Cheng Wei, how does it feel to be in the sky! Are you scared in your heart?" Zhai Fang just looked at Yang Chengwei and asked.
"Yeah! Cheng Wei, the last time you went to heaven, I heard that you heard some knocking in the middle of the night. What the is going on. In space, how could anyone knock on the door!" Jing Tianpeng of course also heard about what strange knocking sound Yang Chengwei heard in space. He still does not understand what is going on!
Yang Chengwei now pretended to be mysterious and said: "Hey, it's really scary! I thought it was haunted at the time! I thought to myself, are there ghosts in this space too! How come you meet in the middle of the night The ghost knocking on the door. I'm really scared. But fortunately, there is no big problem. Thinking about it, it is not a serious matter."
"Hey, what is the reason for that!" Zhai Fanggang and Jing Tianpeng still don't know what caused the percussion.
After the completion of the space mission this time, the percussive sound is of course an internal matter. It was not made public. After all, this will affect the mood of other astronauts in the future. It's better not to make it public.
However, Zhai Fanggang and Jing Tianpeng are not others, they are both good friends of Yang Chengwei. Of course, he can talk to these two friends about this matter.
Yang Chengwei almost knew what was going on now. Of course, he is not sure. After all, Zhao Zhongyao said, and what he said was just speculation. Before really seeing those so-called small celestial bodies, no one can prove that the percussion sound Yang Chengwei heard that night was caused by the impact of these small celestial bodies.
"This problem, Mr. Zhao and I, and President Cheng, have already studied. Mr. Zhao speculated that it may be caused by small celestial bodies in space. He said that in space, there are also some very small space particles. These things are in space. Flying at will, just like bullets. In fact, their speed is much faster than bullets.
When these small celestial particles collide with the space capsule, they can certainly cause certain harm to the space capsule. However, these small celestial particles are very small, probably similar to bullets. Such small celestial particles, even if they hit the space capsule, are unlikely to cause much damage to the space capsule.
But for the astronauts in the space capsule, they will definitely be shocked. The knocking sound I heard that night may have been caused by these small celestial bodies hitting the door of the space capsule.
But Mr. Zhao said, all this is just his speculation. He wasn't sure if it was so. One of your flying missions this time is to find out the cause of the strange 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 very reasonable. It is likely that some small celestial particles hit the door 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 flew to the sky, could this unsolved mystery be solved.
"Cheng Wei, don't worry! This time we two will fly for nine days, we will definitely catch that'ghost' for you. At that time, you have to teach it a lesson." Zhai Fanggang looked at Yang Chengwei again. Made a joke.
"Yes, Cheng Wei. This time, we are two of us flying for nine days together. No matter what happens, there will be a response. We will definitely catch the culprit who scared you." Jing Tianpeng After listening to Zhai Fanggang's words, he also echoed this sentence.
"Haha, okay, then please two." Yang Chengwei also laughed.
Besides, Zhao Zhongyao's current work is also very stressful. On the one hand, he wants to train Zhai Fanggang and Jing Tianpeng. On the one hand, we must quickly design a new space suit! After all, the space suit designed for Yang Chengwei last time was not able to meet the needs of this space mission. He must now design a new space suit.
Space suits are personal airtight equipment that guarantees 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 the human blood will turn into a gas, causing the volume to expand. If a person does not wear a pressurized and airtight space suit, his life will be in danger due to the large pressure difference between inside and outside.
Space suits are multi-functional garments developed on the basis of pilot airtight suits. Early space suits could only be used by astronauts in the cockpit of the spacecraft, and later space suits for use outside the cabin were developed. The modern new type of extravehicular space suit has a liquid-cooled cooling structure that can be used by astronauts to perform activities outside the space capsule.
In addition to the various layers of the astronauts used in the cabin, the extravehicular spacesuit has three layers: one is a vacuum insulation layer, which is used to protect the astronauts during extravehicular operations or activities on the surface of the moon and other stars. Invasion of overheating and overcooling of the environment outside the cabin can also prevent heat loss inside the clothing. The second is the liquid-cooled suit, which is made by changing the gas in the ventilation and heat dissipation layer tube of the space suit in the cabin to 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 relying on gas to dissipate heat, and the liquid cooling medium can dissipate the heat well. The third is the outermost layer. In addition to the functions of preventing high heat, abrasion and protecting the internal layers, it also has the function of preventing solar radiation and the interface for connecting other equipment.
For example, it is connected to the umbilical cord during extravehicular activities of the astronauts, connected to the body-carried life support environmental equipment, and the space maneuvering flight mechanism. The helmet of the space suit consists of a helmet shell, a face window structure and a collar.
There are two types of helmets used in manned spaceflight, soft and hard, among which hard helmets are divided into two types: fixed and rotating. Most of the soft helmets are used as components of the space suit in the cabin. The rotating helmet has an airtight movable bearing on its collar, but the increase in sealing links will reduce the airtightness and structural reliability, and increase the design difficulty.
Zhao Zhongyao knew about the design features of extravehicular spacesuits before he was alive. 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 has been training Zhai Fanggang and Jing Tianpeng while also starting to develop a new generation of outer space suits.
Fortunately, everything went smoothly. Six months later, these two tasks have almost been completed.
Of course, other scientific researchers are not idle, they have developed a space capsule and a flight capsule. The space mission this time is different from the last time. This time, the astronauts should not only stay in the capsule, but also move out of the capsule!
The return cabin is obviously not suitable for out of the cabin activities. To allow astronauts to move out of the cabin, it is necessary to design a new flight cabin. Let this flight capsule and the space capsule for return be connected together.
First use a rocket to launch this space capsule and flight capsule into space together. Then, let the space capsule and the flight capsule fly together in space. The astronauts can stay in the capsule first. When they need to perform the mission, they come out of the space capsule and then come into the flight capsule.
In the flight module, the astronauts have to complete the exit activity. After they have completed the task. They returned to the ground in a space capsule. And that flight capsule will stay in space.
During these six months, Zhao Zhongyao was also very busy. On the one hand, he needed 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 help Cheng Yu and the others successfully develop the space capsule and flight capsule used in the second space flight.
Although the return cabin used by Yang Chengwei last time has already been recovered. And it looks good. Manned spaceflight is a high-risk job. There is no problem at all. It is something that requires 100% success.
So, even the space capsule recovered last time, there is not much problem. But when a new space experiment is to be carried out, this old space capsule will not be used anymore. It is necessary to develop a new space capsule. Only in this way can the safety of the astronauts be fully guaranteed.
