A new material for the Soyuz launch vehicle has been created in Russia

To launch the Soyuz-ST from the Guiana Space Center, the holding RT-Chemcomposite (part of Rostec) created catalysts and one of the main materials in the production of the rocket is boron fiber, reports press office company.

“The developed catalysts work in driving the turbopump aggregates of a special booster catalyst. Boron fiber, in turn, is used in the manufacture of metal composite materials for the spacecraft frameworks, ”the release says.

“For Soyuz-ST, we have created a unique and unique research and testing base in Russia, where we study the effectiveness and control tests for certification and certification of industrially manufactured catalysts, as well as highly concentrated hydrogen peroxide of various grades. The specially developed fiber has a unique strength of 3200 MPa, a coefficient of variation less than 15, a tensile deformation of 2,8% and at the same time the diameter remains 140 μm ”, - quotes the press service of the general director of the holding Kirill Shubsky.

It is noted that the technology developed by the enterprise for the production of special catalysts "is used in the aggregates of the engines of the Soyuz, Progress, Soyuz-FM, Soyuz-2" launch vehicles.

“Another development of RT-Chemcomposite, boron fiber, is one of the most popular reinforcing materials with high characteristics. It is used in the manufacture of metal composite materials based on aluminum as a matrix, which are successfully used in the manufacture of prepreg tapes. Such tapes are used in aviation for the manufacture of horizontal and vertical stabilizers, tail, spar frame, fastener elements, ”the message said.

The press service also noted that “the latest developments of the holding are widely used in the creation of space technology and ensure the fulfillment of the tasks of the federal space program, including in terms of manned space flights from both traditional space centers and the Kourou cosmodrome in South America, where 15 of successful launches of the Soyuz-ST launch vehicle took place. ”

Well, here again, by a strange coincidence, one cannot see or hear "guardians for Russia", and even about these, like their ... polymers ... about the gas station, somehow, somehow, somehow it is not heard ... there would be an article in the spirit of "Russian scientists failed ..." dancing until the morning would have stood ... with a whole range of comments ...

[Finches]

As Turchinov would say, Ukrainian is better than Russian ...

But seriously, it’s always nice to read about what's new created by Russian specialists in Russian production!

I’ll add my own 5 kopecks. Weekly report:

[Damir]

Well, dear Lukich ... how to comment on this without obscene vocabulary is not clear ... there are already two bans, enough for now ...

[Lord_Bran]

Forgot to mention that Ukrainians were also building. With the help of specials. reception "kangaroo".

[Damir]

Could and build .. specialists and very serious in Ukraine were ..

[parkello]

Damir, as I understand you ... he himself also has two bans for the same thing. in the sense of "magic Russian words" I even stopped commenting after that. for there is nothing real to say.

[Damir]

What!?!?!? We have moderators and in Greek are so strong ???? how to live (comment) more ...

[parkello]

I don’t know if they are also strong in Greek, but in Russian, yes I generally rarely express myself. that day I saw I drank a lot, and fell on someone. well ... had to cool for 2 weeks. Now when I drink to a laptop I don’t fit, well, or just stick out on Facebook. it can be expressed in full, weighty and capacious

[Damir]

Yes, too, it fell on one dill ... and before that I mentioned the Baltic states in conjunction with the verb .... uhhh ... well, indicating the event of the loss of a thing in a military-connected way ...

[parkello]

it happens yes. my nerves are naughty too, I’m a straightforward person, if I can say right in my eyes that I’m thinking about him (them, her) and I won’t bother with choosing words. Well, I’m directly saying, excuse me, I don’t speak languages. I mean at the level of ... as I can, as I can ... but in the case. here. Well, anything happens. and so I try not to engage in dialogues and disputes with anyone. I’ll give you a muzzle on the street right away. But on the Internet, it’s somehow not pulling, although sometimes I drink it and lose patience.

[Damir]

but it’s not that nerves were naughty ... I simply begged .... sometimes it is necessary, despite ... but not knowing the laws does not relieve me of responsibility ...

[hirurg]

AAA well, yes, it's boron fiber!
Clear! That nothing is clear.
Though comparative characteristics would give.

[Giant thought]

An article for narrow specialists, but it's still nice that our technical idea does not stand still, and produces such advanced materials that not all countries can master their production, and Russia with a "torn economy" here gives you such know-how.

[Temples]

Surgeon, why do you need comparative characteristics? If anything is not clear !!! Just to whine, damn it.
Well done and created. So the reliability of the media will be higher.

The creators of this fiber do not know how to cut out appendicitis and do not require comparative characteristics of scalpels.
Surgeon, everyone does his own thing.

[hirurg]

1. The surgeon, why don’t you need to ... I haven’t drunk vodka with you yet.
2. If you are reading stupidly, not trying to understand anything (well, at least how much stronger, better or not at all) I try to understand
3. If I express my point of view, it doesn’t mean whining at all. (By the way, it’s not the first time you’ve expressed such expressions in relation to website visitors). Let's somehow respectful,))))
4. Why should I, not for you to judge. Ways as they say ...

[marshes]

Boron fiber seems to have been used for a long time, though on ballistic missiles.
Back in 1985, in the magazine Young Technician there was an article with the title and maybe I am mistaken for a year - Woven rocket.

[hirurg]

Young technician speak? Ballistic say?))
Smiled.

[Grbear]

Smiled? This is you in vain. At one time, Yuniy Tekhnik and a bunch of other magazines that "painted" the technology of the future, were the object of close study by the special services of "advanced" states.
In young animals, thinking can give such "twists" that Einstein will clap his hands

[Altona]

About gunpowder, new ones would write something that is being developed as new fuel.

[Holoy]

What is Guiana? Which Kuru? All money for Rockets and launches Arrested in France! Workers with miserable salaries Sit! Rostec generally lost touch with reality!

[sdc_alex]

Just for fun, I'll give you a plus sign.
Thanks, smiled.

[x.andvlad]

Well this is not forever. And the development and development of technology in any way needed.
And the article says clearly: ... including in terms of manned space flights as with traditional spaceports, and from the Kourou space center in South America ...
So, not one Kuru lives.

[Alex_Rarog]

It’s good that we are developing!

[Gormenghast]

This is a problem in the pension system of the Russian Federation, and everything is in order with pension rockets. Next year, we will just mark the 60th anniversary of the first launch of the R-7.

Unfortunately, two mutually exclusive points flow from this:
1. R-7 - an excellent missile - well-developed, reliable, cheap, which had a significant margin for modernization.
2. Russia cannot create a new rocket that is not inferior to the Soviet one. Angara is a show; she doesn't fly anywhere. Indians and Chinese already have hydrogen, but in Russia it was not there, and it is not.

Well, what are you so worried. Soon Turchinov, the whole country, in a pool of flax, will begin to purchase missiles.
As soon as we eat canned food from hedgehogs!

[Gormenghast]

Soon, Turchinov, the whole country, in a pool of arms, will begin to buy missiles

According to the clinical statement of Turchynov, I can only assume that he read a lot of the Ukrainian press, which declared Antares a Ukrainian missile Although there is Ukrainian - only the first step, without an engine; true, the whole step. It is clear that without the Russian engine - at least you can do it yourself in steps - you won’t fly anywhere.

Well, what are you so worried.

It annoys us that the Chinese have practically bypassed us. The Great Campaign 5, which successfully flew on November 3, is Energy in miniature. Oxygen-kerosene sidewalls + hydrogen center. And in terms of carrying capacity it already surpasses both Proton-M and Angara A5.

[KCA]

China yes, it’s bypassed, only Russia built a cryogenic plant for it, it plans to build 4 more, so they make hydrogen + oxygen, but with fuel, like kerosene-oxygen, I’m sure that building engines without Russia is just , also could not do without fraternal assistance of the Russian Federation

A strange statement. For why step on someone else's rake? Remember what the "Zeppelin" age has rolled back from

While stupid politicians and vile greens will impede the creation of nuclear power engines, hydrogen will remain the most energy-intensive fuel in space.

Nuclear engines for outer space. No sane person will use them on carrier rockets. At least at the present level of development of science and technology.

[kas1]

Where did he go? Carrier Energy for Buran, there is hydrogen, oxygen. All powerful generators have hydrogen cooling, etc.

And what do you want to do with the backlog of "old" missiles? Throw away the time-tested and money-making technology?

Quote: Gormengast

Indians and Chinese already have hydrogen

Of course there is, but in the bravura news they don't write about the cost of maintenance and the number of maintenance personnel required to maintain cryogenic systems. They will not write about the unprecedented safety measures required to work with liquid hydrogen either. They will not read about the risks of destroying the half of the cosmodrome either. And no one will be interested in reading about the monstrous associated costs. Or do you think hydrogen can be "just put into the tank"? The lion's share of the cost of the Buran space program was precisely the cryogenic equipment and its maintenance at the cosmodrome. So it's a show, it's more likely in China and India.

Did you know that launching a hydrogen rocket costs three times more than launching a "kerosene" one and four times a "hydrazine" one? No? Well, I will enlighten you: it means that it is cheaper to make at least two launches with "conventional rockets" than to bash show-offs with hydrogen. Two, Karl!

That's why the cons were canceled on the site ...

[Gormenghast]

And what do you want to do with the backlog of "old" missiles? Throw away the time-tested and money-making technology?

Nothing like this! This is stated in paragraph 1.

Did you know that launching a hydrogen rocket costs three times more than launching a "kerosene" one and four times a "hydrazine" one? No? Well, I will enlighten you: it means that it is cheaper to make at least two launches with "conventional rockets" than to bash show-offs with hydrogen. Two, Karl!

Hydrogen:
1. Significantly raises the payload, so the whole digit is forced to bring to the denominator of the effectiveness of the rocket system.
2. Reduces the number of required degrees, that is, again, reduces the cost, and increases reliability (purely mathematically, at least)
3. Only hydrogen, and then at the limit of technical capabilities, provides the removal of ST in one step. And this is the dream of astronautics.

The optimal disposable rocket system is the first stage - kerosene (where fuel density is more important than specific impulse) + the second stage - hydrogen.

[Bayonet]

The best option is a hydrogen + fluorine pair. Fluorine-hydrogen fuel exceeds oxygen-hydrogen by about 5% in specific impulse and twice in density. But the difficulties of the technical plan - fluorine is terribly aggressive, do not yet allow the use of this powerful oxidizing agent in rocket science.

[KCA]

and the exhaust will produce hydrogen fluoride, fluoric acid, which even eats away the glass, therefore it is stored in plastic bottles

[Bayonet]

Work on fluoride-hydrogen fuel did not go beyond testing model combustion chambers of engines, when specialists finally fully appreciated the possible damage to the environment, not even the accident of a "fluorine" rocket, but simply an oxidizer leak, which, as practice has shown, is difficult to avoid. Work on fluorine-ammonia and hydrogen fluoride blocks was discontinued. It is interesting to note that the American work on the use of fluorine as an oxidizing agent for carriers and spacecraft was closed for the same reasons, although a little earlier.

[guzik007]

Another development of "RT-Khimkomposit" is boron fiber - one of the most demanded reinforcing materials with high characteristics. It is used in the manufacture of metal composite materials based on aluminum as a matrix,
-------------------------------------------------
If I understand correctly, then the parts "twisted" from this fiber are additionally reinforced with aluminum, maybe powder technology, or anodizing, or something more abrupt.
In general, this is good news.

[Operator]

Boron fiber in the form of microscopic fibers is added to molten aluminum.

In principle, standard carrier tanks of multi-stage launch vehicles can be made from this metal composite. In this case, the parasitic weight of the structure can be halved and the payload weight can be increased from 4 to 10 percent of the starting weight.

The use of borometal also makes it possible to switch to the use of a single-component cryogenic fuel methane + oxygen, which has a better specific impulse, cheaper and more technologically advanced than a two-component mixed fuel kerosene + oxygen.

As a result, the cost of putting payload into space will decrease by an order of magnitude.

[guzik007]

So that's where the dog rummaged! thanks for the answer.

Mathematically and according to calculations, everything is always beautiful, that's why she is mathematics. But when it comes to practical use, there are nuances that are of little interest to theorists, but provide engineers and practitioners with a headache. Economic expediency? Safety? Overhead? No, I haven’t heard.

To use hydrogen steps, it is necessary to build entire cryogenic plants and storage facilities at the cosmodrome. It costs a lot of money, eats a breakthrough in electricity, and therefore radically affects the cost of launch.

"Dream of cosmonautics" is not cryogenic stages (these are overly expensive and dangerous technologies of the 60s level), but multi-mode engines (turbojet engine - scramjet engine, turbojet engine (ramjet engine) - scramjet engine - taxiway, etc.), air / stratospheric start ", etc.
