New astronaut wardrobe: seemingly ordinary but with "connotation"

This long vacation has just passed, and the researchers in the Key Laboratory of Modern Fashion Design and Technology of the Ministry of Education of Donghua University have not rested for a day: upgrading the "wardrobe" of astronauts is one of the reasons why they are busy.

Space suit is a typical high-tech product, and every upgrade contains the wisdom and sweat of researchers. From the first manned spacecraft "Shenzhou 5" to the upcoming "Shenzhou 13", from solving the problem of outer protective materials for extravehicular spacesuits to developing and designing special spacesuits for astronauts, the research team of Donghua University participated in the design of each generation of spacesuits.

"China spacesuit not only has higher and higher technology content, but also represents the national image with a design full of China elements, highlighting the style of a new generation of' flying'." Li Jun, head of the R&D design team of astronaut costume of Donghua University and dean of the School of Fashion and Art Design, revealed that the new technology used in the research and development of space suits has also promoted the progress of clothing materials and cutting technology in more special industries and even ordinary people.

From satisfying functions to giving consideration to beauty and fashion, the design of space suits is becoming more and more exquisite.

The spacesuit worn by astronauts, even seemingly ordinary in-cabin work clothes and ground training clothes, actually has "connotation".

"At first, when we participated in the design of spacesuits, the first consideration was to meet and ensure the functional requirements, ignoring the beauty. But now, we can make these special work clothes look everyday and fashionable through design. " Li Jun told reporters that the special costumes of the "God 12" astronauts have incorporated rich design elements with China characteristics, showing the charm of China's traditional culture to the whole world and the whole universe.

Nearly 20 years ago, a joint research group composed of nine disciplines of Donghua University solved the bottleneck problem of extravehicular spacesuit manufacturing technology-extravehicular spacesuit coating. This is the "armor" of extravehicular spacesuit, which is softer than leather, thinner than lens and lighter than mobile phone, but it can protect the safety of astronauts' spacewalk like "armor".

However, at that time, this core technology did not have any information and physical objects to refer to. Donghua University team worked together to tackle key problems, and finally completed this high-tech material with tear resistance, wear resistance, thermal radiation resistance, meteor resistance, chemical corrosion resistance and ion radiation resistance, and achieved a breakthrough in high temperature resistance and radiation resistance.

With the development of science and technology, the design of space suit is more exquisite. Li Jun took the live video of the "Space Travel Trio" as an example. Many people still remember these pictures: astronauts usually wear work clothes in the space station, change into sportswear when pedaling bicycles, and also use casual clothes, weightless protective clothing, bedding and so on.

More than 30 kinds of astronaut-specific clothes developed and designed by Donghua University team can help astronauts to resist the adverse effects of weightlessness on human muscles during long-term' space flight', while others can care for astronauts' emotions and moods. At the same time, the design also takes into account the details of photography, video recording and display effect after image transmission in the cabin light environment.

In addition to clothing, astronauts' "space home shoes" were also developed by Donghua University. Brand-new materials ensure the comfort and safety of astronauts' feet when they carry out activities in the weightless environment of spacecraft cabin and space station.

Continue to tackle key problems for decades and help the development of the space industry in all directions.

Walking into Donghua University and chatting with the teachers and students here, what impressed the reporters most was the pride unconsciously revealed in their eyes and words. Hold up a "space umbrella", weave a pair of spacecraft's "glass wings", and even make an intimate "space toilet" ... In fact, since the launch of China's space industry, Donghua teams from different disciplines have been accustomed to "teaming up", breaking down discipline barriers, working together, and devoting themselves to all-round scientific and technological research in the space industry for decades.

In the 1980s, the research team led by Professor Panding from Institute of Materials launched a key research on the technology of "neck sticking", and successfully developed aerospace-grade high-purity viscose-based carbon fiber at 1994, making China the third country in the world to master this technology.

In the Textile Institute, Professor Chen Nanliang's team developed the "key material of glass fiber grid for semi-rigid panels", which weaves glass fibers into threads and fabrics and inserts "glass wings" for cargo spacecraft such as Tiangong-1, Tiangong-2 and Tianzhou-1, making the spacecraft lighter, but with higher strength and longer service life. The "Spaceborne Antenna Metal Mesh" innovatively designed and manufactured by the team is the space umbrella of the spacecraft, which breaks the monopoly of foreign technology and greatly improves the communication capability of China's high-performance satellites.

The high-reliability passivated glass of the spacecraft used in the "Shenzhou V" manned spacecraft comes from the senior engineer team of Han Wenjue of the Institute of Materials. This enables the high-power rectifier of the control system to resist ultra-high temperature or ultra-low temperature in space, and can also prevent the strong radiation of photons, neutrons, protons and other particles in space, and accompany China space hero Yang Liwei to fly into space for the first time.

The team of Professor Yuan from the School of Chemical Engineering and Biology conducted multidisciplinary research on major problems in daily life, and finally developed a "space toilet"-"HYF" urine collection and emergency feces collection device, and successfully applied the developed space hygiene materials to the space life of astronauts.

More high-tech clothes will "come to the world" and make ordinary people wear healthier and smarter.

Generations of researchers from Donghua University not only took a series of "indomitable" scientific research achievements, but also took the initiative to undertake major national space missions such as Shenzhou, Tiangong, Beidou and Chang 'e, and began to descend to the world with their own efforts. In the words of a young researcher, in the near future, more ordinary people can dress healthier and smarter like astronauts.

In space, the extravehicular spacesuit may experience the test from 100 degrees Celsius to tens of degrees below zero in one minute. Therefore, an important part of the extravehicular spacesuit is the liquid-cooled suit worn close to the body, which can keep the temperature of human body in a normal state all the time. However, it was not the astronauts who tried on this high-tech costume first, but the warm-body dummy developed by Professor Zhang Weiyuan from the School of Fashion and Art Design of Donghua University.

"Whether the spacesuit is qualified or not depends on these dummies." Li Jun told reporters that this high-tech technology developed for the manufacture of spacesuits will gradually benefit more ordinary people in the process of commercialization and popularization, such as the research and development and testing of new fabrics and baby clothes.

"It is difficult for a baby who can't talk to clearly express whether his clothes are soft, sweat-absorbent, hot and cold, etc. This requires the development of more advanced fabrics and designs to meet people's new needs. " Li Jun said.

The crew of Shenzhou XIII officially announced that the Shenzhou XIII manned mission is the sixth and last mission in the key technology verification stage of the space station. Its main purposes are:

① Carry out experiments on key technologies of space station assembly and construction, such as mechanical arm assisted cabin transfer and manual teleoperation;

(2) Conduct 2-3 extravehicular activities, and install dual-arm combined adapters and suspension devices of large and small mechanical arms to prepare for the subsequent space station construction tasks;

(3) Further verify the health, life and work support technology of astronauts staying in orbit for 6 months;

④ Carry out scientific and technological experiments and applications in space medicine, microgravity physics and other fields, and carry out diversified popular science education activities;

⑤ Comprehensive evaluation of the functional performance of each system in the project to perform space station tasks and the matching between systems.

Why does space travel have to be a threesome?

Wang Xiang, the commander-in-chief of China's manned space station system, once said that astronauts must be three astronauts on the space station at any time. In the space station, the three astronauts have different tasks and scientific experiments, including space technology experiments, space technology experiments and biomedical experiments.

This year, the pace of manned space flight in China is a bit "open". Before the National Day, three astronauts of Shenzhou 12 manned spacecraft just returned to land after a three-month business trip. After the National Day, three more astronauts will be sent into space for a "business trip". This time, the three astronauts will travel for a longer time. They will travel for six months. As for the specific number of days, the exact data currently known is 183 days.

Wang Yaping is not only a female astronaut, but also carried out the Shenzhou-10 mission, successfully completed various tasks including "teaching in space" and was awarded the honorary title of "Hero Astronaut".

At present, the development speed of China's space industry is constantly improving, from the time astronauts were in space. This year, the time for two business trips in space has increased from three months to six months. Ordinary people may not feel this time, but it is conceivable that staying in space for 1 minute will increase the degree of danger, technical difficulty and cost pressure. It is conceivable that a person is consuming energy in space, survival and work, but at present he can't achieve self-sufficiency in the space capsule. Some people may say that solar energy can be used more efficiently in space, and with solar energy, a steady stream of electricity can be generated. However, if people live and work in space, they will inevitably need food and other energy supplies. You know, the transportation cost of sending "express" from land to space is very amazing.

It is also known that the Shenzhou-3 spacecraft before the National Day has transported the materials needed by the astronauts of the Shenzhou-13 mission to the space station.
