"From zero to one" innovation continuously

[Struggler is youth]

The vast starry sky, invisible exploration.

In the past few days, the news of the successful flying flying of Shenzhou 14 has made all Chinese children jumping. But there are a group of young people who have doubled pressure. They sleep less every day, and have been working for longer.

This is because during the Shenzhou 14th mission, China Space Station will be built into the National Space Lab. And this group of young people who start the "workaholic" model are the main force of the development of the National Space Lab -the Chinese Academy of Sciences Space Application Engineering and Technology Center Integrated Technology Center team.

"The core of spatial science and application is to explore unknown and innovate. Our work is completely 'from 0 to 1'." Wang Ke, director of the Integrated Technology Center and Deputy Chief President of Manned Aerospace Engineering Space Application System, said When they first received the task 10 years ago, the average age of the team was less than 30 years old, and everyone didn't even know what the space laboratory should grow.

Due to Western technology blockade, China has not been able to use the space laboratory of international space stations. "This is why the team ignited the fighting spirit." Said Tang Shanping, director of the scientific experimental cabinet of the Integrated Technology Center, said, "Starting from the" two bombs and one star ", the more breakthroughs, the more breakthroughs, and the tradition of China's aerospace industry. "

"Compared with the space laboratory of the International Space Station, we are more difficult." Wang Ke introduced that the size of the international space station that deploy 31 scientific experimental cabinets is 423 tons, and the size of the Chinese space station with 25 scientific experimental cabinets is only the size of the Chinese space station. It is 180 tons. "A scientific experimental cabinet is equivalent to moving a ground laboratory into space, and its complexity is no less complex than a satellite." He emphasized that "this means that our scientific experimental cabinet must be lighter and more functional. "

For 10 years, the team has been exploring and breakthrough in scientific research. "Everyone's flying task scientific load is almost new, and it is the innovation path from 0 to 1 '." Tang Shanping said, "No experience can learn from, a seemingly small problem often goes through hundreds of hundreds of problems, often through hundreds of hundreds of problems, often through hundreds of hundreds of problems, often go through hundreds of hundreds of problems, often go through hundreds of hundreds. Trying and experiments can have a set design. "

In this regard, the team member Guo Dongcai felt the same. As the person in charge of the project of the spatial application system and the rail storage device project, he encountered many technical bottlenecks. For example, a tracking experimental device for storing low -temperature samples, using insulation materials, it is easy to rupture, using pressure -resistant materials, but not insulating, finally finding suitable new materials, the factory will not process it ... "Tosses back and forth tossing back and forth ... It took half a year to make it. "Guo Dongcai said," This situation is the daily life of our work. "

"Without some cold and bone, how can we get plum blossoms." After countless trial iterations and overcoming difficulties, the team broke through more than 30 key technologies to reduce the weight of the scientific experimental cabinet. For more than double, the overall performance has reached the international advanced level.

On March 23, 2022, Shenzhou -thirteen astronauts showed the world for the first time in the second lesson of the "Tiangong Class" to show the "high -gravity scientific experimental cabinet" and "no containment material experimental cabinet", which has attracted worldwide attention.

Ten years of grinding a sword. "These two scientific experimental cabinets are the first batch of results in our team." The integrated technology center applied by Fan Dianwen, the designer in charge of the fluid circuit, said that behind the first batch of experimental cabinets, there is a collective charge.

In the early morning of September 30, 2020, the three scientific experimental cabinets in the core cabin began to set and test the final state. The team must complete the assembly and debugging of more than 100 sets of equipment and hundreds of processes, and to test and confirm hundreds of work conditions. But according to the schedule, it was only 8.75 days for them.

"Struggle is the brightest background of youth, and action is the most effective grinding of young people." Fanmian's memory has remembered so far. "The team quickly organized the youth commando. Plan, fight against time, sprint all the way. "

"In those days, everyone was in the office in the office. When I was sleepy, I found a corner for a while." As the youngest member of the team, Li Zhenxiang had just graduated from the 90s. He was convinced by his colleagues' hard work: "Everyone nailed to his post like a nail, and finally completed the task on time with zero errors."

In April 2021, Tianhe's core cabin successfully flew the sky with the first three scientific experimental cabinets. The team members are even more busy -in the second half of 2022, asking the Tian Tian experimental cabin and the Mengtian experimental cabin will carry 12 scientific experimental cabinets to launch, and jointly form a national space laboratory with the sky and the core compartment.

The sky is dreaming, and the country is the country. "There are 20 large characters on the wall of the ground test hall, 'particularly hard -working, special fighting, special can be checked, and special dedication'. In this team, I deeply feel that a person's youth can only glow with brilliant glory by integrating into the cause of the country and nation. "
