航天服制作过程Spacesuit production process

In almost all science fiction movies, has appeared in the spacesuits, and we are in the real space experiments to see a far cry from the former are tight design, like Spider-Man found that a flexible layer of the skin more pliable, but as a spacesuit, They do not appear in red; but in reality it seems that the spacesuits of the total can not shake off the heavy rigid form, which looks like a spacesuit Inflation of the balloon, which was wrapped in the astronauts to do regardless of what action, Would seem difficult, clumsy.

     Although science fiction movies, not enough to contrast the spacesuits standards - in the true test of space, the spacesuits safety and practicality is the most important function - but at least the performance expectations of a more flexible, more light And more humane, like a real clothes, and this is our vision for the future spacesuits.


     Fortunately, the area of aviation and space scientists never to ignore such expectations. More flexible, more humane, this is also an expert on spacesuits have been since the research. They would like to see developed a close to the skin of the spacesuit, spacesuits that will not impede the traditional spacesuits like people, should be to control the weight of 45 kg, while the traditional spacesuits are often weighed 150 kilograms.


     The Massachusetts Institute of Air Space University professor of Dawa. Newman (Dava Newman) is such a portable spacesuits study one of the cast members, and her companion were the spacesuits that is called "biological services" ( Biosuit). Late last year, they launched the "biological services" as a model, this model has solved many aspects of life, just as the original version, also suitable for use as space walk. However, Dawa, a professor and her colleagues hope that we can develop an improved version in 2012 in order to be able to "American landing on the moon again," plans to take a leading role.

 


Close to the skin of spacesuits



 

"Biological services" to retain the muscle movement "campaign line" to ensure that the activities of the agile


     Massachusetts Institute of Technology's Institute of Air Space scientists often this will be close to the skin of the spacesuit is called the "hybrid product", from the traditional spacesuit is now down to 150 kg of 45 kg. "Biological services" in fact adopted a completely different operating principle, but its life-support system was almost unchanged traditions of the spacesuit design, it will be back in behind the astronauts in space activities For the astronauts to provide food and oxygen.


     Spacesuits and traditions, "biological services" for the astronauts must create an environment similar to the Earth and the micro-environment in order to ensure the survival of mankind; however, the use of traditional spacesuit is a kind of "inside the pressurized spacesuits" for aerospace Members of the creation of atmospheric pressure, which is the traditional look very cumbersome spacesuits.


     "Biological services" using a "mechanical counter-pressure" approach to pressure to achieve. Spacesuits and traditions, "biological services" is to take the design of multi-storey structure, in addition to underwear layer, heat and perspiration levels, Dawa, a professor or a can be accurately shaping the memory alloys, as a "biological Service "to pay a lightweight, flexible," bones. " In this pay, "skeleton" outside, Dawa, a professor cast a mixed layer of high-fiber insulation made of fabric radiation, and then in this layer fabric coated with a layer of the coating, in order to allow the fabric to extend a total loss Sex. And between the bones in the fabric, a Dawa, a professor of polymer gel filling into the gel in the heat of these conditions will be very easy expansion.


     Wearing such a "biological services", the astronauts in space to implement the task of the spacewalk, spacesuits once felt the heat, whether radiation from space or from its own astronauts to breathe, this temperature is sufficient for the condensate Expansion of the rubber up. However, the expansion of the gel can not out-proliferation, because the surface of the fabric is strained, so can only squeeze inside, which will be squeezed into the final with a pressure of the gas pressure inside the spacesuit and the effect of the same However, the "biological services" will not become bloated and at the same time eliminate the need for gas compression equipment weight.

 


"Well-designed spacesuits"

     This was close to the skin of the "biological services" and the traditional spacesuits what is essentially the difference between what? Professor Dawa, said: "Traditional spacesuits are in order to complete certain tasks to create, but the 'biological services' is a well-designed spacesuits."


     In space, weightlessness and because of the huge volume of spacesuits, the astronauts will tend to weaken the operational capacity of 40% in space when they completed a task, even for a simple action that they can hardly be easier. But the "biological services" can guarantee security in the same time, the astronauts can maintain a certain deGREe of flexibility and a sense of strength.


     Dawa, a professor and her research team have used 3D images in research or power walk at the time of muscle movement, they finally found in the muscles during exercise will have some role in supporting the power lines, the Dawa, a professor of her " Biological services "in accordance with these lines of sewing patterns, to ensure that the lines of those in the movement, always Rouren Duo and flexibility, and other parts of the spacesuit is tight, play a role in the protection and isolation.


     "Traditional spacesuits only designed to be part of the joint bearings, or the need for local activities designed to bend, but the astronauts such activities is still limited, we hope that the 'biological services' is a kind of similar to the second Layer of the skin as spacesuits, the astronauts make it according to its own activities in mind. "Dawa said," it will enable astronauts to the moon or Mars more freedom of action, Rulvpingde. "
