Tell You The Secrets Of High-Tech Spacesuit.

On the afternoon of June 15th, "

Three astronauts appeared in the spacesuit.

On the following day, the Shenzhou nine astronauts' expedition ceremony was held at the Jiuquan astronaut apartments' sky Pavilion, which is an important ceremony before Liu Yang's expedition.

It is reported that the Shenzhou nine spacesuit is not simply a garment, but also a personal protective system for astronauts. It is a personal closed equipment that ensures astronauts' life activities and working ability.

With the development of the aerospace industry, the astronauts used today can be said to be the fourth generation of spacesuit.

It is possible to solve these problems in the weightlessness environment, and the problem of scratching is the biggest "malpractice" and can only be controlled by astronauts.

China's independently developed "flying sky" extravehicular spacesuit has a total weight of 120 kg, with a cost of about 30 million yuan, and a reliable coefficient of 0.997. It can work for 4 hours in the space environment, and has the functions of environmental control and life assurance and extravehicular communication.

Astronauts generally need to put on the spacesuit while the spacecraft is rising, changing the orbit or falling down, or when the cabin is leaking and the pressure suddenly drops.

The astronauts put on the spacesuit in the cabin and connected the oxygen and gas supply system in the cabin. The clothing will immediately pressurized the gas supply and provide some temperature protection and communication functions, so that the astronauts can still return safely when the leak occurs in the cockpit and the pressure suddenly drops.

During the emergency of the cabin pressure, oxygen supply to the helmet is provided to ensure the ventilation and heat dissipation of the astronauts' respiratory oxygen and pressure clothing, the elimination and dilution of the moisture discharged from the exhaled gas and the two carbon emission.

When the airship cabin pressure is normal, it is used to supply oxygen, remove carbon dioxide and water, and ventilate and dissipate heat.

Design features of Shenzhou nine high-tech spacesuit:

1. camera: "flying sky" helmet also equipped with cameras, can shoot astronauts out of the cabin operation scene.

2. helmet: there are 4 layers of face windows, two of which will be filled with high purity nitrogen.

There is also a protective window on the outside, and the outer layer is a filter window. The refractive index of sunlight is very low. Once the astronauts face the bright light, they can pull down the window.

3. arms have Chinese characters: the left arm of spacesuit is bright red.

On the right arm, the Chinese character "flying sky" and "flying sky" are the first generation of extravehicular spacesuits developed by our country. The overall design and the design and assembly of all components are completed autonomously.

4. gloves tactile: gloves have only one layer of air tightness on the fingertips, which can keep touch.

Three dimensional scanning technology is used to produce gloves suitable for Asians. Sensitivity can help astronauts hold pencil thickness.

5. portable ventilation device: 3 astronauts carry a small box in each hand, and there are tubes attached to spacesuits on the box.

Experts explained that this is a small portable ventilation device, with power and fans, can connect cabin power supply.

6. working socks in the cabin: antibacterial socks are suitable for cabin WORK SOCKS fitted with the working clothes of the cabin, and the working shoes worn after returning to landing use the structure of hard bottom and soft side shoes.

7. safety hook: the 2 safety hooks on spacesuit are very important for this task.

When it comes out of the cabin, the hook can play a role of safety protection, so that the astronauts will not leave the cabin.
