The Most Expensive Clothes In The World

< p > > What does astronaut wear in space? During winter vacation, the "China dream technology dream" exhibition organized by the China Manned Space Engineering Office, sponsored by China's a href= "http://www.91se91.com/news/index_c.asp" > Science and Technology Museum < /a >, gives viewers a clear view.

< p > astronauts wear the world's most expensive "a target=" _blank "href=" http://www.91se91.com/ "> clothes < /a >.

Spacesuits can be classified into space suits and extravehicular spacesuits according to their functions.

Astronauts usually wear spacesuits in the cabin when the spacecraft rises and falls.

Extravehicular spacesuit is the support and support system for astronauts in the open space activities when they leave the cabin.

< p > extravehicular spacesuit fabric is made of advanced mixed fiber, which has the characteristics of high strength, high temperature resistance, impact resistance and radiation protection.

It can supply oxygen and bring special battery to resist low temperature.

It has an ecological pack on its back, many of which are stealthy.

The whole spacesuit weighs about 120 kilograms and is worth about 30 million yuan.

Compared with the spacesuit in the cabin, there are more protective layer, liquid cooling layer and vacuum insulation layer.

< p > spaceflight obeys external confinement, namely, confining layer, airtight layer and wetting layer.

The limiting layer is made of high temperature resistant and abrasion resistant materials. It is used to protect the a target= "_blank" href= "http://www.91se91.com/" > clothing < /a > inner structure, to ensure that the astronauts wear comfortable fit; the air tight layer is made of fabrics coated with butyl or neoprene to prevent the gas leakage from the pressurized clothing; the wetting layer is connected with the underwear, and there are many pipes, which use the ventilation or ventilation to send the airflow to the head, then flow to the limbs and trunk, and collect them to the total outlet through the body draught, and take away the heat generated by the human body metabolism.

The whole space suit weighs about 10 kilograms, which is worth millions of yuan.

< p > a small box raised by the astronauts before the attack is ventilation.

Before the spaceship gets on the spaceship, the astronaut needs to breathe through the small box and drain off the excess heat of the human body.

This device is only used on the way to the spaceship, not on the spaceship.
