What is the material of Shenzhou VII 20

The launch of "Shenzhou VII" is imminent, but you may not know that the raw materials used in the extravehicular spacesuits of the "Shenzhou VII" astronauts and the ** umbrella of the return capsule are produced and provided by Chengdu Hairong Special Textiles. Yesterday (10th), Li Feng, a senior engineer of the company, revealed that the raw materials of the "Shenzhou VII" spacesuit were delivered to Beijing for testing as early as the end of last year, and the textile wire used in the spacesuit and the first umbrella is comparable to the "first price".

**Umbrella: 300 kg per rope.

Flame retardant, wear-resistant, high strength, light weight, red and white, special-shaped design.

The special raw materials for the "Shen VII" spacesuit and the first umbrella were completed at the end of last year and delivered to the Beijing Institute of Aerospace Medicine for early testing. Li Feng said that the first umbrella can be different from ordinary aviation umbrellas, it is made of special polyester materials with high strength, light weight and good cushioning, and the umbrella has an area of 1,200 square meters.

Revealed: The raw materials used for ** umbrellas include more than 10 varieties of umbrella clothing materials, parachute ropes, connecting straps, sewing threads and so on. Li Feng introduced that the first umbrella of the spacecraft return capsule has very high requirements for the flame retardant, wear-resistant, strong, elongated, and weight of textile materials.

The raw material of the umbrella is special polyester, which is quite thin. **The umbrella is supported by 96 lines, each with a length of 46 meters and a weight of only 2 grams per meter. Each rope can withstand a tensile force of 300 kg.

The "Shen VII" return capsule ** umbrella adopts a special-shaped design, composed of red and white colors, and the strength on both sides of the umbrella is higher than that in the middle. At that time, 96 paracords will support the first umbrella, and the return capsule of the "Shen VII" spacecraft will land in a perfect posture with the help of the first umbrella.

Spacesuits: adapt to various special environments.

Good elasticity, strong radiation resistance, ultra-low temperature resistance, and high price.

In fact, after the 'Shen VI', we began to develop the spacesuit material for the 'Shen VII'. Li Feng said that the company had previously provided raw materials for spacesuits for the "Shen V" and "Shen VI" spacecraft, but they were all cabin suits, and the spacesuits of "Shen VII" had higher requirements for raw materials, to meet various special environments such as ultra-low temperature and strong radiation.

Revealed: As a special textile manufacturer, Hairong has been working on research and development since the 80s of the last century. Since it is impossible to produce spacesuits in large quantities, the raw materials produced by the company are also produced in small batches.

It is understood that the raw materials for the spacewear are provided by Hairong Company from head to toe, and high-strength brocade silk is used to connect all aspects of the clothing. Li Feng said that sometimes for the connection line on the head and hat of the spacesuit, it is necessary to go back and forth to Beijing many times to discuss and prove, "although the ** per kilogram of this kind of line is only more than 100 yuan, but the cost of the exchange is comparable to the ** price!" "The raw materials of these spacesuits are quite elastic, and the inner layer of the fabric is wrapped with rubber, which is resistant to ultraviolet rays and radiation.

1. Shanghai Baosteel Special Metal Materials Co., Ltd., the main material supplier of the hull.

2. Dolby in Germany, specializing in providing in-cabin touch screen technology for the entire spacecraft. Implement the mode of operation at the fingertips. The company is most familiar with the core technical support of all touch products in China.

3. Ansell Limited, the world's largest manufacturer of latex products, provides latex materials for the entire spacecraft**, which are mainly used for warehouse doors and pressurized isolation and closure systems. Ansell Limited may not be familiar to everyone, but everyone must be familiar with his condom brand JSB.

4. A new generation of remote sensing technology, control technology for spacecraft and ground and long-distance ships. The technology is jointly completed by ten large international companies and scientific research units.

5. Spacecraft isolation technology for airlock compartments. The three cores of the technology have been satisfactorily addressed. The recharge oxygenation technology is completely self-developed and has a high level of safety.

6. Self-developed spacesuits, materials and properties of spacesuits and spacesuits of the Soviet Union. But the performance has reached the world's advanced level!

Shen VII was successfully launched at Jiuquan Satellite Launch Center at 21:10:04 on September 25, 2008! The astronaut who served as Shenqi was Zhai Zhigang.

Liu Boming, Jing Haipeng, and the three! Successfully landed in Inner Mongolia at 17:38 on the 28th!

I was too trembling to grow my own wheelstool to see the Ladong Brigade.
