Name what functions and features a spacesuit should have

Spacesuits. There are five functions: 1. Maintain the astronaut's body temperature.

2. Keep the pressure flat and change the sail balance (so that the pressure on astronauts is similar to that on Earth). 3. Block strong and harmful radiation (such as radiation from the sun). 4. Dispose of astronauts' excrement.

5. Provide oxygen and extract carbon dioxide.

Dear, <>

Hello, glad to answer for you. The power of the spacesuit, the bridge and the ability are important. Spacesuit role:

Hold the astronaut's body temperature; Maintain pressure balance; Blocks strong and harmful radiation; disposal of astronauts' excrement; Provides oxygen and removes carbon dioxide. There are two types of spacesuits: intravehicular spacesuits and extravehicular spacesuits; The sensitive staring used by the United States and Russia are both hard-and-soft spacesuits. No matter what kind of spacesuit is composed of multiple layers, they are connected to each other to form a whole pure clothing, but the quality of each layer is required to be high, light, and not too thick, so as not to affect the astronaut's movement.

The spacesuit worn by the astronauts is made of several layers of super-strong fibers and other materials, and it is strong enough to guarantee that it will not break in the vacuum of the universe.

The 9 10 layers of protection include a variety of materials and fabric layers, such as straight fibers (a Teflon fiber that combines Kevlar fiber with breakage protection), an aluminized Myra film layer reinforced by polyester plain weave fabric, a nylon fabric layer covered with neoprene, a polyester fabric, a nylon fabric layer covered with polyurethane, a polyurethane impregnated film, multi-fiber stretch nylon, an ethylene-vinyl acetate tube with a water coolant inside, and a nylon thin silk lining designed for astronaut comfort.

However, the main goal of spacesuit protection is not vacuum tension, and the more direct threat actually comes from the failure of the lead and seal of the spacesuit and the drastic change of temperature: the impact of a tiny meteorite will break through the small hole in the spacesuit, causing internal pressure to leak out; The surface temperature of the spacesuit rises sharply when the astronaut is on the Sun-facing side of the Earth, and drops sharply when the cavity is on the Sun-facing side.

The life support system inside the spacesuit provides the astronaut with breathing air and maintains a stable temperature control system, while the backpack on the back provides the required pressure to the life support system.

The spacesuit can provide oxygen and protect against environmental factors such as vacuum, high and low temperatures, solar radiation and micrometeors in space. Since there is no air pressure, the volume of gas contained in the blood will expand violently, resulting in the life of the astronaut in danger, so the safety of the astronaut is ensured by pressurizing the spacesuit.

High stability. It should be stable enough, and it can be firmly fixed in low cold, high temperature, or other expected environments, and will not expand and shrink in heat.

High reliability. Like a paratrooper's parachute, it must be 100% reliable and 100% open during any skydive.

High durability. It is necessary to be able to complete all the tests according to the space program. For example, some wear-resistant parts must exceed the planned life of several times as a qualification standard.

High-tech. Whether it is the core device chip, fairing, the latter spacesuit and anything else in aerospace products, it is the most cutting-edge technology at present, such as the shell material of the rocket, and the lightest material must be selected to meet the standards of rocket use, so as to reduce the overall weight of the rocket to transport larger satellites.

The spacesuit has excellent heat insulation, high temperature resistance, low temperature resistance, and is not afraid of sudden changes in high and low temperatures in outer space, and can also resist the powerful space radiation in the universe.
