"Spacesuit" Donghua University Shenzhou No.12 Astronaut Series Special Clothing Embodies Textile Strength

Since the launch of Shenzhou 11 in 2016

After five years, Donghua "technology + design"

Accompany the astronauts on their journey to space again

Just now, shenzhou-12 manned spacecraft sent three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, into space. They will become the first batch of "occupancy personnel" in the space station and core module. The series of special clothes that guarantee the whole process of astronauts' space and ground work and life, as well as the astronauts' cabin shoes for space station missions, all come from the innovation and hard work of the research and design team of Donghua University for many years.

Three "handsome men" dressed in "space costumes" reappear the starry sky

At the meeting between shenzhou-12 astronauts and reporters on June 16, three astronauts dressed in the regular clothes developed by the astronaut clothing research and design team of Donghua University appeared in the sky Pavilion of Jiuquan Satellite Launch Center. In order to ensure the whole process of astronauts' working and living in space and on the ground, the research and design team of Donghua University has designed a series of special clothes, which include not only the working clothes, exercise clothes, leisure clothes, weightlessness protective clothing and sleeping gear for astronauts working and living in the space station, but also many kinds of ground mission clothing such as regular clothes, mission training clothes and special clothes, These special-purpose clothes should not only ensure the realization of a number of special functions, but also integrate the design elements with Chinese characteristics, so as to become the "space Chinese clothes" for astronauts to appear in the world.

"Chinese astronaut's special clothing is a multi-functional garment with functional and ergonomic priority, which has aesthetic quality. The astronaut clothing R & D and design team of Donghua University has integrated the era elements with Chinese characteristics in the surface accessories, color patterns, and even the sewing trace of clothing details, showing the beautiful image of Chinese astronauts as space dreamers and guardians of the Chinese dream." Professor Li Jun, head of the astronaut clothing R & D and design team of Donghua University and Dean of the school of fashion and art design, said.

The styles, colors, patterns and textures of the full series of spacesuits and accessories should not only match each other, but also be compatible with the cabin environment. They should not only reflect the cultural elements with Chinese characteristics and the characteristics of the times, but also reflect the professional characteristics and spiritual outlook of the astronauts. Different types of clothing with different functions can help astronauts fight against the adverse effects of weightlessness on human muscles during long-term space flight, and some can also protect astronauts to adjust their emotions and moods. At the same time, the display effect of photography, photography and image transmission in the cabin light environment should be considered. It can be said that "the same dish must satisfy hundreds of stomachs".

For example, in the design of astronaut's regular clothes, the elements symbolizing the earth's skyline and outer space color are added on the basis of the sky color of lake blue, so that the clothing looks more three-dimensional and full and more layered. Most of them are three-dimensional straight lines. The "s" shaped arc of the front shoulder metaphors the space flight track and the V-shaped straight line of the front chest symbolizing victory, presenting the beauty of thick, thin, straight and harmonious.

In addition to the clothing itself, the design of some clothing articles worn by astronauts should be systematically planned according to the color and shape of clothing. Among them, the main line of the astronaut honor logo is like the trajectory of a spacecraft flying in the blue universe, which gives people a sense of upward flight. The number of five pointed stars indicates the number of times the wearer performs manned missions. Through the comprehensive carrier of astronaut special clothing, the team shows the connotation and style of "flying sky" with artistic design.

Travel nine days with flying clouds

Tianhe core module is the "space home" for astronauts. It provides three times as much space for astronauts as the tiangong-2 space laboratory. It is equipped with three independent bedrooms and a toilet to ensure the astronauts' daily life for up to three months. Living in the "big house" for a long time, of course, is inseparable from a pair of comfortable and beautiful "home shoes" (shoes used in the astronaut space station mission module).

"A journey of a thousand miles begins with one step." The three astronauts "soar up to 90000 Li" and must do a good job in their feet“ The shoes used in the astronaut cabin should be "flexible" to protect the safety and comfort of the feet, and at the same time, the fashionable design and heavy culture should be taken into account According to Zheng Rong, head of the research and design team of the astronaut cabin shoes of Donghua University and professor of the international fashion science and innovation center of Donghua University, the design and development of cabin shoes integrates the school's advantages in many fields, such as anthropometry, ergonomics, materials, 3D modeling, rapid prototyping and product design, And obtained the support of industry resources and related cooperative enterprises and units. The relevant advanced technologies and achievements based on ergonomics are applied to the greatest extent, and the three-dimensional foot scanning technology, plantar pressure analysis, integrated weaving and other technologies are combined, and the design influencing factors including the special environment of the space station, the characteristics of human body, and the demand of sports are carefully and comprehensively considered.

The shoes used in the cabin are mainly made of thermoplastic materials and blended knitted materials. They are soft, light, environmentally friendly, antistatic, breathable and elastic, which ensure the comfort and safety of the astronauts' feet when they are carrying out activities in the weightlessness environment of the spacecraft cabin and the space station. At the same time, the cross size design is adopted for the cabin shoes. The size system can cover multiple male and female astronauts, and the foot morphological changes under various working environments are considered to match the foot movement characteristics of astronauts. Considering the microgravity state and the weight requirements of the spacecraft, the shoes used in the cabin are much lighter than ordinary shoes worn by ordinary people.

The wave like structure of "fish ribs" is tried in the foot modeling, which ensures the unity of flexibility and protection, so as to cushion the collision caused by astronauts' movement. The front and back of feet are full in design, which not only makes the wearing more comfortable, but also makes the shape more three-dimensional. The final color is the combination of "deep blue" and black color. Black reflects the factors of fashion and technology. At the same time, it matches with the blue of cabin work clothes to realize the harmonious sense of visual collocation.

The highlight of the cabin shoes lies in the sole. On the basis of ensuring the functionality, the hollowed out design of the sole originates from the artistic design changes of seal script and Chinese characters. The "stars" surrounded by the outer ring not only show Lingyun's great ambition of "daring to explore the moon in the nine days and catch turtles in the five seas", but also the Chinese style romance and feelings are on the paper.

The indissoluble bond between Donghua University and "China Aerospace"

In fact, on the development road of national major projects promotion and construction, we can always see the figure of Donghua people's dedication. Take aerospace as an example. As early as the 1980s, Donghua University began to use scientific research to assist Chinese people in aerospace exploration.

Professor Pan Ding of the school of materials of Donghua University, led by Professor Pan Ding, has successfully developed the "aerospace grade high-purity viscose based carbon fiber" booster missile, which fills the gap in China and makes China the third country in the world to master the technology.

After three years of research and innovation, Professor Zhang Weiyuan's team from school of clothing and art design of Donghua University has completed the research on the "extravehicular space suit thermal manikin system" for extravehicular spacesuit. The data of metabolic energy, heat transfer and skin temperature of astronauts wearing extravehicular space suit under simulated outer space conditions are given by using the thermal manikin, It has played a key role in supporting and supporting the first Chinese astronauts to leave the cabin.

Personal "convenience"

Since the project of manned space engineering research was established in 1992, Professor Yuan Qinhua of School of chemical engineering and biology of Donghua University led the research group to carry out multidisciplinary research and successfully developed the "astronaut urine collection device", which makes the "convenience" of astronauts in flight or emergency become convenient. In 2003, Zhu Quan and Yuan Qinhua presided over the project of "Research on outer protective materials of extravehicular spacesuit" which was selected as one of the "top ten scientific and technological progress of Chinese colleges and universities" by the Ministry of education in 2002.

The "highly reliable passivated glass for spacecraft" developed by Han wenjue, senior engineer team of School of materials, Donghua University, has been successfully applied to Shenzhou-5 manned spacecraft, accompanying Chinese aerospace hero Yang Liwei into space for the first time. Research team of Donghua University participated in the development of satellite borne antenna metal mesh

As the key material of solar panels, the "semi-rigid solar cell substrate glass fiber grid" developed by Professor Chen Nanliang of the textile School of Donghua University has successively and successfully served the launch of "Tiangong 1", "tiangong-2" and "tianzhou-1" cargo spaceships. The team also successfully developed the "satellite antenna metal net", which played a crucial role in China's Beidou navigation satellite, mobile communication satellite and other series of satellites, creating a history of independent research and development of metal mesh antenna for China's satellites.
