Astronauts' Space Boots: Each Type Of Material Has An ID Card.

The astronauts shoes and boots have the overall function of "dustproof, pollution prevention, radiation protection, anti static and anti piercing".

In addition to high material requirements and complex technology, the production process also has very strict requirements. From production to astronaut wear, there must be no dust.

Don't underestimate these two pairs of boots. The birth of each pair is a systematic engineering operation, and is also an important part of astronauts' safety assurance.

Two pairs of space boots made for Chinese astronauts are also displayed on the stage of the new China group, which has undertaken the Shenzhou series manned spaceflight project.

Xinxing Group Shanghai special footwear company has repeatedly studied, experimentation and close inspection to ensure that the standards of space boots have reached a new high.

Compared with the previous boots, the "God eleven" series boots have been innovated and optimized in terms of gas permeability, portability and manufacturing technology under the premise of ensuring the functions of antistatic, anti dust particles and radiation resistance. The function and cleanliness of the protective shoes have been ensured, and the safety requirements of astronauts in the space capsule environment have been met.

China's first pair of astronauts boots shoes were born in 2000, designed for the first Chinese astronaut Yang Liwei.

Wu Junjie, chief designer and senior engineer of the emerging China group, and general manager of the Shanghai special shoe and shoe branch, introduced the command of the general equipment, and quickly carried out the research with the team.

Wu Jun Festival said,

Generally, it is divided into lining, leather, bottom leather and protective layer. According to the different functions of different places, in order to meet the requirements of "dustproof, anti pollution, radiation protection, anti static and anti piercing" for the footwear of astronauts, a total of hundreds of materials have been tested on the whole pair of boots. "These materials are the result after our targeted screening."

Wu Jun Festival said that the bottom leather and the face leather are a difficult part.

"After the boot material is identified, raw materials and process preparation will begin."

Wu Jun Festival said that the whole process has nearly harsh technology and quality requirements, and the production standards are strict.

In order to be able to effectively monitor, "every product has its own identity card": the main material, auxiliary materials, ingredients must have a test report, the processing and production requirements of personnel and machine fixed, each product is responsible for each process to ensure quality.

After nearly 3 years of hard work, in 2003, Yang Liwei, the first Chinese astronaut, traveled to the outer space wearing boots made by Wu Jun Jie's team.

The expedition boots displayed in this air show are the grey boots worn by the astronauts at the time of their expedition and before boarding. The protective clothing for the hatch is the white shoes worn by astronauts when they enter the heavenly palace two when docking with heavenly palace two.

At the time of the launch of the God nine, due to the addition of Liu Yang, a female astronaut, Wu Jun Jie's team also redesigned the cabin boots with the characteristics of the female body.

"After returning from space, the relevant departments have referred to Yang Liwei.

He proposed amendments to space boots.

Wu Jun Jie said that this is China's first pair of space boots, and how it should be improved and Yang Liwei has the most say.

Wu Jun Jie said, "this is also our tradition. Every time the astronauts perform their tasks, we will ask them for advice on comfort and application of shoes, so as to constantly improve the craft of shoes."

"But no matter how to improve, there is one thing we must stick to."

Wu Junjie said, for space boots, from the production process to the astronauts wearing, "the most important thing is to ensure that there is no dust, no dust can be found, even a large sesame dust can not be, because it may threaten the safety of astronauts and become a waste product."

Wu Jun Jie said that especially when he was preparing for the nine Space Boots of the God, he was most impressed.

"According to the regulations, we do not use glue, but we need to make

It is also necessary to ensure the accuracy of one or more layers of material. It is necessary to ensure that when the shoe is made to the sewing machine, it is guaranteed that the shoe material is not contaminated.

Wu Jun Festival said that when making space boots, there are still some places that need to be hand-made, ensuring that the workers do not pollute the boots while working, and it is also very time-consuming. "No makeup, strict cleaning before work is necessary."

The finished boots come out, "even a pen mark on the boot can not be printed."

Making a pair of space boots is a systematic project. "Until now, they are constantly improving."

Wu Jun Festival said.

According to the introduction of xinjihua group, Jing Haipeng and Chen Dong, wearing the new astronauts' boots, pay more attention to humanization, lightness and comfort in the design. The weight of the new products is 370 grams lighter than that of the original products. They are more sweating and breathable in function, and reflect the specialization of aerospace products in appearance.

According to the introduction, each pair of boots of the astronauts is made to order, and all the things that need to be worn in the astronauts boots need to be counted, such as socks.

In the early days, measuring feet for astronauts was a "three-dimensional artificial foot", and the "Shen ten" series shoes were developed with the method of "solid measurement + paste molding".

In this case, the data of original body measurement and plaster mold shaping method are adopted in the cavity of the boot body, so that the design of the last body is infinitely close to the astronaut foot type, and the wearing effect is more convenient and convenient, showing the astronauts' strength and solemnity.
