On May 30, the Long March 2F Yao-16 carrier rocket carrying the Shenzhou 16 manned spacecraft rushed straight into the sky at the Jiuquan Satellite Launch Center, and a few hours later, the long-awaited Shenzhou 15 astronaut crew successfully opened the "home" and welcomed the Shenzhou 16 astronaut crew from afar to settle in the "Tiangong".
Behind this exciting "space division" is the coordinated research of "one arrow for a thousand people, one gun for ten thousand people", bringing together tens of thousands of scientific and technological workers to work together.
On May 30, the Long March-2F Yao-16 carrier rocket carrying the Shenzhou-16 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center.
Three generations of masters and apprentices who "evacuated last"
"Turn in the countdown of 30 minutes before launch!" , Until this time, Chen Wei, Shen Xin, and Han Yu, who were the last batch of staff members of the spacecraft to be launched, successfully evacuated safely from the tower.
Chen Wei, who will retire next year, participated in the development and launch of Shenzhou 1 to Shenzhou 16, and with his decades of accumulated assembly operation technology, he won the "National May Day Labor Medal" and "National Technical Expert" and other honors.
When talking about "only one model in a lifetime", Chen Wei sighed a lot, "This life is worth it, and it depends on the young people later." ”
Under the careful guidance of Chen Wei, the "post-90s" Shen Xin grew rapidly and became the same master of assembly operation as the master. His daily plans at the launch site are always full, sometimes a fierce hoisting commander, sometimes a meticulous "sewing man" for the spacecraft. In the continuous switching of roles, he also passed on the spirit of serious responsibility to the younger "post-00s".
Han Yu, born in 2003, is the youngest member of the test team. Since joining the work, he has followed the master Shen Xin to carefully learn every process and every detail of the assembly operation, and soon mastered the essentials of the assembly work. "I don't have other ideas in mind, so I want to work steadily in the post of assembly operation, train strong skills, and be a first-class aerospace worker like my predecessors."
"Passing the Gang Belt" is like a relay race, in this process, the old, middle and young relay together, and every stick must run wonderfully. It is also this kind of "passing on the help" that continues the spiritual concept of astronauts and continues to write a new chapter in China's space industry.
On May 30, the Shenzhou 16 manned spacecraft was photographed at the Beijing Aerospace Flight Control Center for autonomous rapid rendezvous and docking with the Tianhe core module.
"I" do it right once, and "you" test it carefully
As the final assembly of the propulsion module of the Shenzhou 16 manned spacecraft, Ling Xiaofeng has always adhered to the concept of "doing well the first time and doing it right the first time". In the final sprint stage of this mission, Ling Xiaofeng undertook the test task to promote the operation of the subsystem leak detection and other subsystem filling and inflation tasks.
Due to the particularity of the task, he needs to cooperate with various subsystems to continuously combat and complete each refueling and inflation work in one go. When asked if he needed to change personnel, he always smiled and said, "Don't worry, you are guaranteed to complete the task successfully!" Under his meticulous and meticulous operation, the leak detection of the promotion subsystem passed once, and the filling and inflation tasks of each subsystem were successfully completed.
"Is the installation location clean?" "Is the cable protection in place?" "Is the thermal grease well applied?" ...... Liu Fengjun, the general assembly inspector of the propulsion module of the Shenzhou 16 manned spacecraft, often issued one "question" after another to the general assembly personnel. In his eyes, quality inspection is no small matter, and the four words of "cautious and cautious" are deeply imprinted in his mind.
As a final assembly inspector, Liu Fengjun is like a "scanner", firmly locking every key link in the final assembly process, every requirement of the product, and every operational detail of the process.
Faced with the nine subsystems of the propulsion module of the Shenzhou 16 manned spacecraft and dozens of special assembly testing requirements, Liu Fengjun said, "In the past, we confirmed the signature and took photos of the process documents one by one, although there were records, but we could not do detailed comparison and joint inspection. Now, we use multimedia to record and click wherever we want. ”
"The final assembly inspector needs to do a good job of every 'door', guard every key point, and track and supervise the whole process." Liu Fengjun said that in this way, the product can be sent to space with confidence and provide good quality assurance for the successful completion of the follow-up test mission.
The Shenzhou 16 manned spacecraft successfully docked to the radial port of the space station sky and core module taken at the Beijing Aerospace Flight Control Center on May 30.
The person who created the "armor" of astronaut spacewalk life
Extravehicular spacesuits are the life "armor" of astronauts spacewalking, and nowadays, astronauts work more frequently out of the capsule, and the sealing materials of spacesuits have been repeatedly tested.
Wang Fan, head of the 42 special rubber materials and processes of the four institutes of the Aerospace Science and Technology Group, said that an extravehicular spacesuit contains dozens of seals of different shapes, in addition to meeting various performance indicators, it is also necessary to meet the requirements of hollow and unilateral bonding with non-metallic parts according to human body functions. These joint seals in spacesuits must withstand the space environment, ensuring both a tight seal and flexibility in the joints of the spacesuit.
"Our innerliner products have a complex structure, a thickness of only 0.4 mm, thin walls, curved surfaces, large ripples, high dimensional accuracy, high molding difficulties, and the difficulty of development can be imagined." Wang Fan and his team members created original molding technology and successfully completed the development and delivery of the supporting flight suits for the space station.
From "Shen 1" to "Shen 16", 42 institutes have provided tens of thousands of sealing products for the overall unit of the spacecraft.
"We offer these series of seals with a maximum diameter of nearly 3 meters and a circumference of 9 meters, with an error of no more than 0.01 mm." Wang Fan said that these products have high strength, high tear resistance, high and low temperature alternating resistance, good adaptability to the space environment, the materials used are non-toxic and pollution-free, and the resistance of various space environments has reached the level of similar foreign materials.
