West deprived Russian cosmonauts of safe spacesuits

July 10 2018 14

Western sanctions reached the Russian space.

Firstly, it is known that the United States of America purchased RD-180 rocket engines in Russia. Despite the availability of their own counterparts, Soviet developments attracted Americans with reliability and an adequate price. For the Russian space industry, supplies to the United States were an important source of revenue. However, for political reasons, Washington was discontinued. Space industry experts said that the negative consequences of this decision for the rocket and space industry in Russia will be visible after 2 years.

Secondly, the Russian cosmonauts will experience great inconvenience. The fact is that Russian spacesuits can only be serviced in space, because due to the low carrying capacity of the Soyuz it is not possible to return them to Earth for repair. And cargo Progresses are disposable launch vehicles and burn out in the atmosphere. Currently, only the American Dragon Ilona Mask is designed not only to launch cargo into orbit, but also to return them to the planet. Therefore, American spacesuits are serviced on Earth, and Russian ones are served only on the ISS.

For effective work, domestic spacesuits need to be modernized, made larger, space-saving systems for the astronaut and convenient data transfer. However, as it turned out, this can also cause problems. In Russian spacesuits, components manufactured abroad are actively used. Due to Western sanctions, new designs run the risk of being left without important systems. With the help of domestic components, it will be possible to perform work only at the very minimum level.

Everyone is harmed by sanctions.

There is nothing to chew on the snot .. You must do your spacesuit. More sanctions ... Leonov then in a completely Soviet first went into space.

  Satellites from foreign components, now spacesuits ...

  But people shawal.
  Look how lively they are discussing.
  And how did we fly into space before without "foreign components"?

Naturally, all the necessary country is not able to reproduce in full, but spacesuits in space should already be individual and their own 100%. It’s a shame to even talk about it. And if there really is a war going on in space (and this scum is definitely preparing for it), then what about Russia?

Bullshit. The ability to service spacesuits in orbit has always been a dignity of domestic spacesuits! The cost of putting 1 kg of cargo into orbit reaches 10 thousand green and higher, depending on the carrier, add also the cost of return.

To write this, the author must give a link where he took the information, otherwise empty talk. How dirt divorced sofa experts!

It has long been clear, even in our village, that one cannot enter into close cooperation with the West under any pretext. If it was not possible to unite with the EU in one World, then it is necessary to wait for your World - the World of Socialism, because capitalism in Russia has not taken root.

It seems that the author does not know the essence of the issue at all, or he secretly advertises Ilona Mask.

Complete nonsense, the author is incompetent! Orbital spacesuits, which is a line of 6 variations of the Orlan semi-rigid spacesuit for the Soviet lunar expedition, are very economical to maintain, since they are adjusted right on board the station for astronauts with a height of 165 to 192 cm with a chest girth of up to 114 cm, can be stored for for many years in orbit and are currently suitable for 17 exits, if it is Orlan-MK, and up to 25 exits, if it is Orlan-ISS (if there is a spare third spacesuit on board). Moreover, they are repairable directly in orbit, i.e. because astronauts are able to change the soft shells of their sleeves or legs during the day of work, and the autonomous life support system in the satchel is arranged in such a way that it is difficult, but any unit or unit can be replaced, except for the sublimator heat exchanger (which is what astronauts actually do sometimes at the prompts from Earth starting since 1983). As a result: not only is our spacesuit ten times cheaper than the American one, it does not need to be transported back and forth as an American for maintenance, as Already on the ISS, the Americans discovered that their spacesuits could not be stored on board for six months, although they guaranteed it with papers. In addition, in the life support system, they have the disadvantages of a unit from an electric motor on the drive of which a water cooling pump and a fan are mounted, therefore, from the water circuit, water flows through the seal into the fan and during the exit fills the helmet with water in such "wet suits" to absorb water to this day trivial diapers are used, American diapers, otherwise you can drown yourself like the Italian Paolo Nespoli quite recently. Another serious drawback is that the spacesuits do not withstand large internal pressures and simply burst when the overpressure in it exceeds 1,5 times the nominal value of 0,3 kg / cm2, i.e. they can be destroyed at an overpressure of 0,45 kg / cm2, and in the Soviet-Russian spacesuit it is practically the operating pressure mode of 0,4 kg / cm2 and the safety factor in American or the safety factor in Russian is not 1,5 but three. Thus, Orlan will collapse and burst at the seams of the power shell only at an excess pressure of 1,2 kg / cm2. It is true that working in a vacuum under pressure in a spacesuit of 0,4 is 1,5 times harder than under a pressure of 0,3 kg / cm2 due to the mechanical stress of the soft elastic shells of the sleeves and legs. But the readiness for spacewalk in the Russian spacesuit is 0,5-1,0 hours, which is required by medical requirements to partially remove nitrogen dissolved in the body in order to avoid decompression sickness (not only divers, but also American astronauts in spacesuits with less working pressure). For this reason, Americans are preparing for the exit not 1 hour, but whole days, putting on oxygen masks for an hour to remove nitrogen and locking themselves in the airlock compartment at a pressure of the atmosphere enriched with oxygen lowered to 0,7 kg / cm2. Only in this way, removing nitrogen during sleep and rest, after 12-18 hours they get into the spacesuit with the help of a third crew member, then breathe oxygen in the spacesuit for about 45 minutes before starting the procedure for relieving pressure in the airlock and going out into space. When using only oxygen-containing breathing through a mask in emergencies in space, they will need at least 4 hours to remove nitrogen dissolved in the body before safely climbing into a spacesuit for decompression. They tried to reduce this time to 125 minutes at the expense of additional physical exercise on a bicycle ergometer in 75% of the maximum possible and greatly accelerating blood circulation with a rapid excretion of nitrogen, but they seized decompression sickness and the accelerated sluice mode was canceled, using the antediluvian method of the Apollo-Soyuz experimental program 1975 year. In the 1990s and 2000s, they asked Congress for money to develop a more durable spacesuit that does not impair human mobility, just like a Russian spacesuit with an increased nominal pressure of 0,4-0,56 kg / cm2 and are still creating their spacesuits Z-1, Z-2, Z-3 and sculpt the second skin of the high-altitude counterpressure-compensating suit "Biosyut". There is no end and end to this PR, as well as a concrete result of the modernization of the EMU ISS spacesuit in the Mega EMU. The only problem of Russian spacesuit builders-materials is that they destroyed the Soviet industry, capable of producing good, durable, wear-resistant synthetic materials, for example polyurethane, used for the Orlan-MKS pressurized shell (i.e. modernized for an international station with a computer and synthetic, rather than rubber hermetic shells).

How pleasant it is to read such kind of reasoning-horror stories. Collaboration implied opportunities, now they are disappearing. So what? One must always be prepared for this. The market is both fierce competition and possible bankruptcy. Today, a partner sells you a product, and tomorrow offers a new price that does not suit you, and the other agrees. You lost if you hoped to come to an agreement with your own benefit. Capitalism with its market does not allow any relaxation, it is worth gape and problems begin, sometimes fatal. You can’t stop - they will trample. Such is the essence of capitalist relations. Of course, our socio-economic experience is different, and this is its value. Copying someone else’s experience is not enough, it will lead to a dead end and loss of independence.

Custom article. Liberal author also invented a provocative title. Ignore such affectors.
