Detailed explanation of the first manned flight task during the construction stage of the space station -Huang Weifen, chief designer of the visiting manned space engineering astronauts

Xinhua News Agency June 4th. Question: Detailed explanation of the first manned flight task during the construction stage of the space station -Huang Weifen, the chief designer of the Chinese people of the Chinese Aerospace Engineering Aerospace System, Song Chen, Li Guoli, Hu Yan China Manned Aerospace Engineering Office On the 4th, the General Headquarters of the Flight Mission During the Space Station stage decided that the Shenzhou No. 14 Flight Passenger Group consists of astronauts Chen Dong, Liu Yang and Cai Xuzhe. Three astronauts will be stationed in the core compartment and stay in the track for 6 months. This is the construction stage of the China Space Station. Following the second flight mission after the successful launch of the Tianzhou -4 freight ship in May 2022, it is also the first manned flight task at this stage.

From the development strategy of implementing the "three steps" of the manned space project in 1992 to the current outfit of Shenzhou 14, the Chinese flying dreams extended to a farther sky. What are the main tasks of Shenzhou 14 Flying Passenger Group? What are the selection criteria? What are the new highlights of clothing and food in space? Huang Weifen, chief designer designer designer of China Manned Aerospace Engineering Aerospace System and a researcher at the China Aerospace Council Research and Training Center, accepted an interview with Xinhua News Agency. Nine types of combinations, 5 times to docking … The task of Shenzhou 14 multiplied mission is complex and difficult. Is the task of building a space station more required for astronauts? Huang Weifen: This year we have to have two manned flight tasks, which is the manned flight task of our space station construction stage.

The Shenzhou No. 14 Flight Passenger Group is going to perform the first manned flight mission during the construction stage of the space station. During the 6 -month flight, the flight conditions that the astronauts had to experience were extremely complicated, including nine combinations, five -time delivery docking, 3 separation evacuation, and 2 converting tasks.

In the process, they have to monitor status and implement manual control operations to meet and docking; they must also be stationed in the two experimental cabins: the first experimental compartment of the day and the dream sky compartment to complete the establishment of the manned environment; The cabin completes the unlocking and installation of more than a dozen scientific experimental cabinets; and daily assembly, construction, maintenance and maintenance. It is worth noting that they need to use the air gate to perform the outlet activities for the first time. We plan to do 2 to 3 out -of -the cabin activities. It is the first time that the small robotic arm that asked the test compartment for the first time for the outlet is used. There will be a compartment event with a composition of the arm and the arm. These are all new states, challenging for astronauts.

They also have to conduct space lectures and carry out some other space education activities and public welfare activities.

Therefore, this time the task of the Shenzhou 14th multiplication group is extremely complicated, and the requirements for the emergency and fault disposal ability of astronauts are higher than before. The commonality of the three astronauts is particularly serious in the future. In the future, the fourth and fifth batches of astronauts reporters: What rules of the selection of Shenzhou 14th multiplication of astronauts, and what are the considerations? Huang Weifen: According to the overall planning of the project, in the key technical verification and construction stage of the space station, there are 4 people’s flight missions. On the basis of summing up the preliminary selection experience, we have adjusted the selection strategy according to the task characteristics of the space station stage. The principles of overall planning, new and old matching, inheritance, and development are used to determine and select this four task flight ride groups. We chose the astronauts with flying experience to serve as commander, and each multiplier was the case. When selecting a group, we analyze the requirements of each task and key tasks for astronauts, such as outlet activities.

At the same time, the matching of the individual characteristics and tasks of each astronaut, and the psychological compatibility between them, form a suitable multiplication group.

We must consider age, and we must also consider various factors such as flight experience, and finally determine it.

Their three astronauts are very serious and very careful. They love to study and love, very team spirit, and compatibility. The three of them also have different characteristics. Chen Dong, as the commander, is particularly confident, he is dare to do with things. Frequently put forward your own opinions and suggestions in training and experiments.

Liu Yang is very affinity and has a strong language expression. Cai Xuzhe is very clever, has a strong ability to understand, and accepts faster knowledge of new things and new knowledge.

At present, we have selected three batches of astronauts and will be selected in the fourth and fifth batches in the future.

The construction of the astronaut team must always consider the overall planning of the national manned space engineering, the corresponding task requirements, and the current status of the astronauts. We will regularly select new astronauts to join the space team every other time. According to the needs of the task, we will expand the candidate objects, cultivate various types of experts, so that the aerospace team has always maintained a moderate scale, reasonable structure, and excellent comprehensive quality, which can meet the current and future development needs.

Focusing on risks to conduct targeted training astronauts, space, clothing, food, housing, and transportation continuously improved. Reporter: You just talked about this task and complexity of Shenzhou 14. What targeted training did we launch the astronauts? What are the new highlights of clothing, food, housing? Huang Weifen: From March 2017, we have been fully trained to prepare for the construction task of space station. Some training is common. On the basis of the eight categories of more than a hundred subjects training, we have conducted key intensive training on the new characteristics, new tasks, new status, and new changes of Shenzhou 14 tasks. Low -voltage environment out of the cabin activity training, outlet activity program simulator training, using virtual reality trainers and robotic arm operation training platforms for collaborative training and drills, so that they are proficient in the skills of the cabin activities. There is also a targeted training on focusing on risks, because with the completion of the space station, the combination is becoming more and more complicated, the flight time is also very long, and the probability of problems will increase.

In response to these risks, we need to conduct emergency and fault disposal training. For example, through the deductive learning, practical training and drills, the corresponding emergency fault disposal ability has been strengthened, so that astronauts can Calmly, calm, and effective disposal. The last is to conduct continuous reinforcement training for long -term flight residence, such as the management of materials, physical training, psychological adjustment training, etc. In addition, the two multiplication groups should work and live at the same time.

I think it is mainly to challenge the space station system, such as the recycling guarantee system. For astronauts, when experiments at the ground combination, there is a 180 -day space station manned comprehensive verification experiment. Each of each group of the experimental compartment in the space station has worked for 30 days.

We also conducted rotation work experiments from Shenzhou 14 multiplied group and Shenzhou 15th multiplication group. In the future, rotation of groups will be the normal state. Through Shenzhou 14 multiplied group and Shenzhou 15 multiplication group, it will lay a certain foundation for the future and accumulate experience. Furthermore, astronauts’ clothing, food, housing, and transportation in space must be continuously improved, because clothing, food, housing and transportation have a great impact on flight. Astronauts must live well, live well, and work well, and provide them with various good guarantees and convenience conditions.

For example, this time the food is added, because the tire is more convenient, the juice is not particularly many, and the meat is more dense. Wash it and eat it. From the 13th of Shenzhou 13, we provided personalized clothing for astronauts, as well as Shenzhou 14.

The two groups of Shenzhou 12 and Shenzhou 13 successfully completed the task, and they were in good condition after returning.

Through their excellent performance in the orbit, the science and effectiveness of our country’s selection of training technology and retention protection technology has also been verified, and it also shows that we have the ability to make spacemen complete long -term flight protection.

The successful practice of these two tasks is helpful for our subsequent improvements.
