China Sets Up Thirty Million And One Sets Of Astronomical Spacesuit For Controversy

Spacesuit is the most expensive clothing in history. China's space suit is said to be 30 million yuan RMB, even if you are a top master.

The value is also less than one percent. Well, a few big carat diamonds may be able to compete.

Now there are three countries on earth who are qualified to say that they actually produce and use spacesuit: Russia, the United States and China.

China independently developed spacesuits, but in the end it introduced Russia.

The product has been shortcut.

In April 2004, China and Russia signed a cooperation contract from the Russian new star scientific production Co., Ltd.

According to the contract, the Russian side has developed three sets of Sea Hawk cockpit suits for the Chinese side, two sets of extravehicular spacesuit for low pressure training, four sets of extravehicular spacesuits for water tank training, and four sets of docking systems for the cabin.

After the joint efforts of both sides, the introduction of the extravehicular space suit contract was carried out smoothly.

Shenzhou seven mission, two Chinese astronauts will be wearing "flying" extravehicular spacesuit and "Haiying" extravehicular spacesuit for the first time out of the cabin activities, taking the first step in the Chinese space! Zhai Zhigang is wearing the first set of "flying Apsaras" extravehicular spacesuit developed by China, which has been out of the cabin for about twenty minutes.

Feitian spaceflight is divided into 6 layers: inside and outside, which are made of special anti-static treated cotton fabric, the main air tight layer composed of Rubber Backed air tight layer, composite joint structure, the limiting layer of polyester fabric, thermal insulation layer through thermal radiation, and the outer outer protective layer.

In addition, the trunk part has more than one layer of shell, which is aluminum alloy thin-walled hardware structure. The wall thickness is only 1.5 millimeters, but it has very high strength requirements, and the compressive capacity is more than 120 thousand PPA.

The limbs of the clothing are equipped with adjusting belts. By adjusting the length of the upper arm, the lower arm and the lower limb, people who are 1.60~1.80 meters tall can wear this suit.

These are the basic support systems, and are also equipped with life support system, control system, telemetry and monitoring system.

The overall weight of Feitian spacesuit reaches 120 kilograms due to its functional and technological requirements.

On the ground, put on

The process is only a few minutes.

But before that, it takes a lot of time to prepare: astronauts wear a body vest after wearing underwear, first wearing a vest that can measure heartbeat and body temperature, followed by anti-static conjoined underwear, and then wrap them up from head to toe with a layer of liquid tight clothing that can heat the body, then put on communication equipment and finally wear out space suits.

In heaven, this process is more complicated.

It takes 15 hours to prepare everything from dressing to wearing.

So after the completion of the space mission, it is said that the cost brought back is even higher than that of the rebuilt one.

Experts explain: the unsealed extravehicular spacesuit is indeed very complicated.

There are 21 operation units for the opening of the cabin. There are only 12 steps to solve the package. The steps are divided into dozens of actions.

Astronauts need tools such as pliers and wrenches to open their clothes.

Therefore, after the completion of the mission, it is very difficult to pack again.

With the limitation of size and weight, astronauts can only leave spacesuits in the orbital module.
