Aviation spacesuit "Vorkuta"

First domestic aviation the spacesuits had a power-type hermetic shell, consisting of 2 or 3 layers of rubberized cotton fabric, which simultaneously performed a power function and ensured the sealing of the spacesuit. One of the brightest representatives of this type were the SI-1 and SI-3M spacesuits.

In 1959, the development of two spacesuits for naval aviation pilots, the C-9 (based on the SI-5) and Vorkuta, began.

In the Vorkuta aviation spacesuit, for the first time, instead of a single pressurized shell made of rubberized fabric, a shell was used, consisting of two separate layers: the outer layer is the force shell, and the inner layer is the hermetic shell.

This was a major constructive achievement: increased reliability, since a more durable technical fabric could be used for the load-bearing shell. The elasticity of the shell has increased, especially in the hinge areas. The manufacturing technology of the power shell has been simplified (sewing and the absence of glue seams), and the assembly time has decreased. In the future, all domestic spacesuits developed by Plant No. 918 (JSC NPP Zvezda were made with a separate shell (power + sealed).

In the power shell of the Vorkuta spacesuit, the lavsan fabric (the Russian analog of the polyester fabric) was used, and the hermetic shell was made of 3-5 mm thick spongy rubber, which also served as thermal insulation in the event of an emergency splashdown. In places of hinges, the containment was made of thin sheet rubber.

The thermal insulation of the spacesuit made it possible to stay in cold water with a temperature of 0-10 degrees for up to 12 hours.

The Vorkuta spacesuit was manufactured in 2 versions: with an oxygen mask and without a mask.

The power system of the hull at the first stage of development consisted of a cable located along the neutral axes of the hull, which, through a system of rollers fixed on rigid pads on the sides of the hull, was transferred to the belt and closed at the front on a winch with a stopper, with which the hull length was adjusted. Subsequently, a power system with a front pull-up was used.

At various stages of development, both spatial (fixed) and rotary helmets were used in the Vorkuta spacesuit. Despite the new approaches to "spacesuit construction", the Vorkuta SC did not find mass application in the USSR Air Force.

SC "Vorkuta" did not find mass application in the USSR Air Force.

Still would...

Unfortunately, many inventions remain unclaimed, such is life.

You need to buy this one during the day on the way out from covid, and at night from the smells of the ROSNEFT plant.

My father worked in Norilsk in the 60s and 70s.
So he said that there was elementary definition of "where the wind blows from"
There were two factories on opposite sides of the city.
If there is one smell in the city, then the wind from this plant and vice versa

In Lyubertsy in the 80s it was always possible to determine the direction of the wind without the Hydrometeorological Center: if it was carrying bird shit (Tomilinskaya poultry farm), then the wind was east, and if it was pork shit (Belaya Dacha), it was south.

if it smelled like bird shit (Tomilinskaya poultry farm), then the wind was east, and if it was pork shit (Belaya Dacha), then it was south.

Maybe in this way they were invited to work?

[Aviator_]

Neither there nor there now nothing smells. Bush's legs and Polish pork in the 90s did their job. And the Tomilinskaya poultry farm was the largest in Europe, I felt it very much through the air.

If from the west it smelled of gray, it means from "Copper", and if from the east of chlorine, then from Nickel, but in the 16th year, production from Nickel began to be transferred to "Nadezhda" and to Nickel to Kola, and later Nickel in the Old Town was closed absolutely. Now only from "Copper" sulfur it stinks, but not so much, after all, they clean gases.

An interesting, unbroken topic, thanks to the author!

I join your comment. Recently there was an article about the first hermetic designs. This is a nice addition.

This is not an addition, but a logical and purposeful continuation;)
Next week I will tell you about the Sokol aviation spacesuit. Then maybe I will pause for spacesuits, so that it doesn’t become boring, and I’ll tell you in detail about installations for moving and maneuvering in space, and not only about 21KS, but also about the UPMK of 1968 and about the Seifer. I don’t want to publish too often, so that it’s not boring, but once a week, a little less often - the very thing.

[Pete mitchell]

Wah well done Interesting and continued with impatience

[Bshkaus]

Interesting and continued with impatience

Greetings! The sequel is already there and even published on my blog;). It's just that I spread here with a delay and only the "cream". But it seems that Yandex-Zen and I do not understand each other: it practically does not give views, for example, an article about "Vorkuta" from December 189 gained only 3108 views, and there were only XNUMX hits in summer. more than seven thousand. So the question is that I write badly disappears by itself, just someone does not know how or does not want to correctly select the audience)))))))

The topic is interesting, here you can only say thank you. But it was clearly worth pointing out at what heights the suit was designed, the pilots of which aircraft were used.

And then all the infa is only about those fleeing, how much it keeps warm in the sea. By the way, pilots don't seem to have such spacesuits now. The story with the death of 3 out of 4 Su-34 pilots in the Tatar Strait is more than sad. Everyone froze before they were found

[Bshkaus]

But it was clearly worth pointing out at what heights the suit was designed, the pilots of which aircraft were used.

My jamb, paragraphs were "lost" when publishing. It’s for the best, I’ll tell you this: the overpressure mode, like on all Soviet spacesuits up to the Yastreb, in which the Leonovs went into outer space, was 0,27 kgf / cm2 (by the way, this mode is still used by the Americans). Starting with the aircraft "Falcon" (not to be confused with the space one), they began to add a spare 0,4 kgf / cm2 in case of altitude-decompression disturbances, but this mode could be used for a short time. Officially, the height of application was 25-30 km, but this is more likely due to the capabilities of the aircraft than the spacesuit itself. It was assumed that they will be used on the Su-9, Yak-25RV and Tu-106 (Tu-128). And now I will spike on my ear - it's not very convenient in terms of use (((.

[Intruder]

Let's take a look !!!

[Intruder]

about "Seifer"

about this construction, if there is data from trusted sources, in more detail ... plizzz !? :)

[Bshkaus]

Do you trust the employees of the company who developed this system? ;)

[Intruder]

Do you trust the developers of this system? ;)

If it is to the developers, and not the marketing department of finished products or the cleaner of industrial premises, then quite !!! :)))

[aybolyt678]

The spacesuit, it is clear that it was Soviet, it really hurt in my soul, because they did it themselves!

[businessv]

Thanks to the author for the interesting article! In the Union, military developments were a closed topic, so it is especially interesting to read about them.
