According to the China Manned Aerospace Engineering Office, at 17:47 on September 17, 2022, Beijing time, after about 5 hours of outlet activities, Shenzhou No. 14 astronaut Chen Dong, Liu Yang, and Cai Xuzhe closely collaborated to complete the outlet event. During the period, all the tasks were set, and the astronauts Chen Dong and the astronaut Cai Xuzhe had returned to the experimental compartment safely, and the outlet event achieved a complete success.
The outlet event is a very difficult and complicated manned space flight task, and each outlet event is constantly drawing experience. After the first out of the cabin at the beginning of the month, what adjustments and improvements did this out -of -cabin event be made?
On September 1st, the Shenzhou 14th multiplication group enabled the air gate to perform the outlet task for the first time. Compared with the previous node compartment, the space staff's activity space is more. But it does bring some difficulties and problems.
Wang Chunhui, deputy chief planner of the astronauts of China Aerospace Council: When the astronauts move in the cabin, when the two astronauts outside the cabin and the two astronauts Liu Yang passed on items to Chen Dong, the distance was more far away. During the transmission process, the length of the safety rope and the distance between Liu Yang's movement may not be as smooth as the node cabin. Where the cabin is placed in, it is the most effective transmission and transfer. The use mode of the safety rope of the two people has been more optimized.
In addition to the optimization of the placement and transfer of items, the position of the upper and lower robotic arms of the outlet event has also been adjusted.
Wang Chunhui, deputy chief designer of the astronaut system of China Aerospace Council: In the first out of the cabin, I also saw that Liu Yang still had some difficulties in the robotic arm. When the robotic arm limits (position), I felt that this position was a bit away from her a bit. Far. This time it is Cai Xuzhe. Each human body size is different. He needs to stop the location of the stop. We have to adjust the position of the upper and lower robotic arm, including the location of the upper and lower robotic arm Essence
It is through this off -class task that designers are constantly optimizing the design location and design process.
Wang Chunhui, deputy chief planner of the Aerospace Council Center Aerospace System: In the early stage, we did not really realize the differences in the heavens and the earth, the weight loss on the physical stability of the person, and the impact of the large objects of operation. We have optimized the distribution of the quality of the entire workbench, including the weight, including the position of the handrail. The improved products are in the mission of God 14, and even Liu Yang's female astronauts can easily complete this operation.
At the construction period of the space station, the spacemen's outlets are dense and need to be installed and commissioned by various types of offensive equipment. During the long -term operation of the subsequent space station, the space officer's outlet will also become the norm.
Wang Chunhui, deputy chief planner of the Aerospace Council Center Aerospace System: The subsequent space station will also involve the maintenance and maintenance of some products during the long -term operation. In addition, in the process of flying for a long time, some loads will be involved, and astronauts may also need to work outside the cabin. Task.
