Beijing Aerospace City is the location of the China Academy of Space Technology and the Beijing Aerospace Flight Control Center, which is responsible for the command and dispatch, flight control, data processing and information exchange of manned space flight missions. At the same time, it also includes the selection and training tasks of astronauts, and the development of spacesuits and aerospace instruments. Xia Yu: They are going to have the first phase of physical testing here today.

In a not very large room, Wang Pengyu and the others Xia Yu were firmly fixed to a chair in the middle of the house, and there was nothing else except for an instrument placed under one of the walls.

"Are you ready?" In front of the operating table of the instrument, a staff member in a white coat asked.

"OK, ready to go." Xia Yu replied.

"Then get ready to begin."

This is the test that you have to go through to become an astronaut, the swivel chair. During the test, the chair, which is not at all comfortable at all, rotates clockwise and counterclockwise, and at the same time swings violently up and down, back and forth, and its main purpose is to test the vestibular nerve function of the astronaut candidate, which is simply to test the astronaut's tolerance to shock and vertigo. Not to mention this thing for ordinary people, even for the astronauts themselves, it is definitely not a good experience, it has nothing to do with enjoyment or anything, its role is very simple, it is to make you dizzy.

As the staff pressed the start switch, the sound of the motor began to sound, and then Xia Yu felt a sudden shock in his body, leaned forward, and then began to spin wildly, turning left and right, constantly turning, and swinging back and forth left and right with no regularity. Even with Xia Yu**'s dynamic vision and physical elements, there was still some slight vertigo at the end of the test.

As soon as the test time came, the staff stopped the machine, untied the safety strap and was about to test Xia Yu, Xia Yu shook his head and said, "I didn't expect to be a little dizzy." ”

A little dizzy? Looking at Xia Yu, who seemed to be completely unaffected, the staff was stupid, he had done this kind of test countless times, and all the previous test recipients must have been more or less affected by vertigo after stepping out of the swivel chair, and a person like Xia Yu who was almost completely unaffected had never met in his work for so many years.

"Follow this straight line, press the red dot in the middle of the wall, and go back the way you came." The staff continued to test the content, Xia Yu listened to the instructions and walked to the position and pressed it, and when he came back, he read a short article according to the test content and read it back, and the test of the swivel chair was completed. Looking at Xia Yu who walked out of the swivel chair test room, the staff wrote down the AA evaluation on the evaluation form, which was already the highest score that could be scored.

After the swivel chair, there's the electric swing, which sounds like an interesting name, but it's a big guy. In the middle of several huge steel frames tens of meters high, an object the size of a container is lifted by several steel arms, and after activation, the people waiting in this container are astronaut candidates, and they will be thrown around.

After that, it is used to simulate the impact chamber of the landing module when it enters the atmosphere, and then there is the centrifuge. Centrifuge training is known as the most painful of all the training for astronauts, and its main purpose is to train astronauts in overweight endurance and the ability to maneuver spacecraft and communicate in overweight conditions.

The centrifuge in the Beijing Aerospace City is the largest manned centrifuge in Asia, with an eight-meter-long rotating arm attached to an oval-shaped enclosed metal pod that astronauts or astronaut candidates are tied to during training. With the operation of the pod, the body will bear an overload force of up to 8 G for dozens of seconds, which is quite a whole body of muscles, bones and internal organs have to bear more than seven times the weight of itself, and it is normal to be pulled by the strong overload force to tilt the face and nose, and it is not a new thing for tears to be thrown out. In addition, the pod rolls and rocks at the start and end, and the astronauts sitting in it have to read the display signal in the pod while resisting the load action with all their might, and are ready to answer questions at any time, which is not only painful, but not ordinary.

However, for Xia Yu, this kind of Cheng dù test will not cause too much pressure on him. In the midst of the countless glasses shattered by the staff and the constant stumbling sounds, Xia Yu passed the basic test of the body with all the excellent results.

The physical requirements of astronauts are not much different from those of the Air Force, and in fact most astronauts are selected from the Air Force. The most basic condition is the physical condition, and after passing the guò, you will have to undergo up to three to five years of professional training, and then you will be able to be selected for a real space mission. But in fact, many astronauts have been staying at the space center until they retire, and they have not waited for a chance to go to space.

However, Xia Yu participated in the test as a test pilot of the aerospace aircraft, and his identity still belongs to the Air Force test flight unit. Because the aerospace aircraft also has to go to space, Xia Yu must undergo a period of astronaut training before he can really join the aerospace aircraft test flight team.

After three months and thousands of tests, Xia Yu successfully passed the selection of astronauts with unprecedented results. Although Wang Pengyu stumbled, he also had a thrilling pass and once again kept up with Xia Yu's footsteps. However, Feng Huaixin actually had a space motion sickness in the gravity-free simulation tank, and unfortunately he was eliminated, and other people in the dormitory were not able to pass Guò for various reasons.

Together with Xia Yu, three former astronauts joined the Shenlong test flight project team, in addition to Wang Pengyu, also became test pilots. Among the other three people, in addition to Wu Degao, who once had the identity of a pilot, the other Du Junbao and Wu Min were astronauts who became astronauts after graduating from the Aviation Academy, and they had no experience in flying an airplane, so they would participate as the second and third mechanics of the Shenlong test flight group, and the captain could only be produced among Xia Yu, Wang Pengyu and Wu Degao, three people who had experience in piloting an aircraft, among which Xia Yu and Wang Pengyu were more likely to become captains because they had the identity of test pilots.

However, the Shenlong manned aerospace aircraft is still some time away from the official launch test, before that, Xia Yu and Wang Pengyu, the other three test pilots, must increase the training of relevant knowledge, after all, this is a new concept of hypersonic aircraft that has never been seen before, and their previous driving experience is still slightly different.

In the following time, in addition to the regular astronaut training, the five test pilots of the Shenlong project test flight team also began to learn and train the relevant knowledge and control skills of the aerospace aircraft. Because of the help of the starry sky, coupled with the knowledge he already has, he quickly completed all the preliminary preparations, whether it was flight control or how many things to deal with, Xia Yu was far beyond the others. Yuan Limin saw this qiē in his eyes, and at the same time he was unceremonious, always pulling Xia Yu's strong man, so that Xia Yu now wears two positions, the test pilot of the Shenlong and Yuan Limin's scientific research assistant.

However, because of this, the advanced progress has made everyone happy, and in two days, this manned aerospace vehicle will usher in its first blue sky journey.
