Astronaut Apparel Research and Development

“I was very excited to see the image of the Shenzhou 11 astronaut appearing on TV. I feel that the astronauts are wearing special clothes designed and sewn by us.” Yesterday, Shenzhou 11 astronauts Jing Haipeng and Chen Dong wore new models. The autumn and winter uniforms made their debut. Seeing this scene, Professor Wang Yunyi, a member of Donghua University astronauts' clothing R&D design team, said this. Starting this morning, "Shanghai Design" will accompany the astronauts to carry out the longest mission of our manned flight time.

Dozens of astronaut costumes

Regardless of spring, summer, autumn and winter, Chinese astronauts always appear in front of the public with a gray-blue one-piece long-sleeved costume. What is the difference this time? The Tung Wah University Astronaut Apparel R&D Design Team designed and developed a series of special clothing to protect the astronauts' space and ground work life. Among them, it includes work clothes, exercise clothes, casual clothes, weightless protective clothing, and sleeping gear for astronauts working in orbit, as well as dozens of ground-based costumes such as uniforms, task training suits, and special costumes. Add a touch of "technology + fashion".

What do astronauts wear after they enter space? It is reported that the Chinese astronauts in orbit sports training and non-working day casual wear designed and developed by Donghua University have been loaded into space on September 15th, waiting for astronauts to come and use them. The full range of space suits have their own functions due to different types: some can help astronauts to resist muscle atrophy caused by weightlessness in long space flight, and some can also protect astronauts to adjust their mood and mood, but also Consider the display effect after photography, camera and image transmission in the light environment of the cabin.

Different from ordinary clothing, enter the Tiangong 2 Space Laboratory to protect the health of the astronauts. The weight loss of each piece of clothing exceeds 1 gram, which is unqualified. If the dimensional error of the special part exceeds 2 mm, it will be reworked.

Tests are done thousands of times during research and development

Li Jun, head of the Astronaut's clothing R&D design team and director of the School of Fashion, said that because of the high reliability requirements of the space mission, thousands of all-round and partial tests were performed on astronauts' special clothing. Strive to complete accurately.

When developing the free-floating spacesuit on the ground, the team specially designed and built the “dressing weightless feeling simulation cabin”, which can simulate the performance of the astronauts in the weightless operation state on the ground, as well as the astronauts' physiological response and psychological feelings. In this cabin platform, it is a critical step for the subject to be able to slide freely to simulate floating. Associate Professor Li Xiaohui finally selected tempered glass that meets the technical requirements. Li Xiaohui personally put on special clothing, connected with various physiological parameter monitoring sensors, and lie on the car for free movement and rotation. "It is equivalent to the heavenly task to perform on the ground first, to find and solve the problem on the ground."
