What is the difference in space service in the city of all over the world?

Text / M

Spaceships are currently divided into compartment space services and overall space services. The cabinet service is mainly used for manned spacecraft launch, returns and guarantees the safety of astronauts during orbital operation; the overall space service is equivalent to a miniature manned spacecraft, which is the ability to protect space for space in the event. And life safety protection equipment. At present, there are only countries that can fully independently master the design and technology of the city space service, and three countries in China, the United States, and Russia.

The overseas space service of the Chinese space station, named “Flying”. It has only one model, regardless of men and women, unlimited size, adjustable body type to each astronaut, meet people from 1 to 1 meter 8 wear. The overall space service is integrated with a soft and hard structure (torso is a hard structure, and the limbs are soft structures), composed of clothing, helmets, gloves and space boots, including 6 layers, with radiation, anti-high temperature, Pressure adjustment, etc., and also has a life-saving system with a weight of more than 120 kilograms.

Astronauts leaving the space station into the space, the astronauts will face a series of tests such as 200 degrees of temperature differences, spatial radiation. At this time, our “Flying”, the space service is the best space for spacefare. There are 6 floors in the overseas space clothes, including liquid air ventilation, pressurized airtight layer, limiting layer, insulation layer, protective layer, etc., wherein the outermost protective material can withstand ± 100 ° C Changes in the left and right; the back is equipped with a portable life security system that provides oxygen, drinking water, etc. to maintain life needs. The glove is the internationally advanced “three-dimensional digital scanning” technology, can hold 25mm pencil thickness. Things, it is tailored for each astronaut.

American Space Aircraft Space Services (EMU) is one of the most advanced outages, consisting of 14 floors, with a weighing 117 kg, and is now available for international space stations. It uses the waist to wear the structure, the helmet can quickly disconnect the neck, and the life-saving system is installed in the non-gas-mounted backpack, and the cabin is connected to the elongated method.

Early flights in the overseas aerospace equipment are in the form of umbilical cords, providing power supply, oxygen supply, and ventilation, etc., which is gradually developed into portable life insurance systems. For example, “Gemini” space service is used by umbilical belt-style insurance systems, the cabin is contained in the cabinet (length 8m ~ 18m) to the failed and controlled various environmental parameters; from “Apollo”, The United States has a portable (backpack) surrogate system.

Russia

Since carrying out manned space activities, the former Soviet Union and Russia have developed 10 types of space service, but only 6 have been used in manned space activities, and the main use is one of them: Hawks -D space suit, Haiying-DM space service, Haiying-DMA space service and Haiying-M space service. The International Space Station is used by the Haiying-M spacecraft, which weighs more than 110 kilograms, which belongs to the fourth modified space service manufactured by Russia.

Russia’s “Haiying” series space service is also a soft-binding structure design, and its overall helmet is integrated with the torso fixation, and the surrogate system is fixed to the door behind the door, and the appearance is similar to the backpack.

In terms of wearing design in the space service, the Sino-Russian space service is “integrated and open-opening” design, or referred to as a back / disengage. Astronauts enter a hinge door from the back of the space suit into the space service; and the early American space service is, the lower partial shading style, the new American cabinet service is improved to “upper part, Entry “.

The US EMU cabin space service can withstand the maximum 8 hours of task time, the working pressure is about 30,000 Pass; Russian “Haiying-M” room space service can withstand the longest 7 hours of task time, work The pressure is about 40 kPa; China’s “Flying” overalls can withstand the maximum of 8 hours. Lower working pressure can make the astronaut’s activities more flexible, which may affect the task species that astronauts can complete.

Insert here: Now there is a urine collection device, but there is no early in the early days. At that time, an astronaut of the United States suddenly wanted to go to the toilet, but he worked in the space to wear more troubles, and it took several hours according to the procedure. When the launch time is equal, in the end, he had to diaper directly in the space service, and he spent a very unpleasant time. Because of this, the United States later developed diaper, then mainly used in space clothes, and later slowly moved to civilians, and became the diaper used by children.

In the decades of the development of the world manned space technology, the United States and Russia have experienced the cabinet space service, and the cabin space service is combined, and then the development route from the cabin space service and the overall space service. China started late, but steady development; although there is still a gap, it is difficult to meet, I believe that we will go more far from the future!
