This astronaut, has been building a space station for 11 years

In the tall and spacious assembly factory building of Wenchang Aerospace launches, the space station asked the Tianyan experimental compartment to complete the three -cabin rigid connection, and it is slowly turning to a horizontal state. Lying down. Throughout the process, Jin Weiwei, the overall chief director of the Tiantian Experimental Machinery of the Fifth Hospital of Aerospace Science and Technology Group, has always been inseparable. The three -cabin docking is the first "big test" he ushered in when he entered the launching ground for more than ten days. "The grades are not bad, the technical state is normal, and the product performance is good."

In April 2011, Master Jin Weiwei just entered the Fifth Academy of Aerospace Science and Technology Group, and he caught up with the comprehensive demonstration of the China Space Station. His entire career so far has spent his overall work in the space station. In the construction of the youth team in the space station, nearly half of the aerospace people like Jin Weiwei, the "station" field, are "station".

The design of the Chinese space station is unprecedentedly complicated. There are many systems, many interfaces, and many status. The traditional two -dimensional design method cannot complete the work at high quality according to the plan. In order to solve this problem. At that time, the three -dimensional digital collaborative design was still new in the field of space. From the top -level planning overall model system, standardized information transmission interface, and the requirements for modeling machine equipment modeling requirements. Point out.

"When I started to do it ten years ago, there are really a lot of difficulties. In addition to changing everyone’s two -dimensional design habits, the three -dimensional information needs to be available, and to guide the production and assembly of the product, which means that the overall overall , Systems, Manufacturing Factory, Total Factory and other units participating in the space station tasks need to be upgraded by corresponding equipment and software. But now it ’s okay, we are not doing it." China Space Station from scratch.

This year, China Space Station will complete the construction of the orbit and enter the rail operation stage. The digital space station located in Beijing Aerospace City will fully ensure the safe and stable operation of the space station through digital deduction and other methods. The digital model made of the space station is used as infrastructure.

As a member of the Sky Experimental Curring Launch of the Rescue Team, Jin Weiwei quietly waited for the launch in the bunker closest to the tower, just like watching his "child", flying to the sky.
