"The most powerful in the world": China tested a new monolithic solid-propellant rocket engine

China has tested the most powerful monolithic solid-propellant rocket engine developed by the Chinese Corporation of Space Science and Technology (CASC). According to the press service of the CASC, the tests were recognized as successful.

The new engine has a thrust of 500 tons and a diameter of 3,5 meters. The corporation said that the company's specialists developed this rocket engine independently using the most modern advanced technologies. At the same time, it is noted that he is the "most powerful" in the world.

The CASC stressed that the development of the rocket engine shows significant progress in Chinese space technology designers. The novelty is positioned as one of the elements in the development of promising heavy launch vehicles for launching manned spacecraft into space and lunar exploration programs.

It is noted that this development is not the only one; the corporation is currently developing a new five-section rocket engine with a diameter of 3,5 meters with a maximum thrust of more than one thousand tons. At the same time, a three-section solid-propellant rocket engine with a diameter of 3,2 meters is already ready. Its thrust is unnamed, but it is said to be the "most powerful" rocket engine in China.

China is quite active in implementing the national space program, conducting several projects at once. Currently, the Chinese have begun building a space station by launching the Tianhe base module into orbit. Soon two more will be added to it, the completion of construction is scheduled for 2022.

Beijing is set to implement a lunar program by building a lunar station. It is for the exploration of the Moon and the delivery of cargoes that a heavy launch vehicle is being developed. By the way, Russia intends to build a lunar station together with China.

China tested the most powerful monolithic solid-propellant rocket engine
"It is made from a single piece of the finest black marble!" Boasted Hottabych.
Well done. They have no time to sing songs, they have to plow. And look, by the way, no Communist Party interferes with them.

"this rocket engine was developed by the company's specialists independently using the most modern advanced technology. " - independently, then they stole everything!

However, if ours stole something worthwhile, and even effective, I would only be happy (at least at this stage of our degradation).

[Finches]

But where is our degradation then? Degradation is in Ukraine, we have confusion and vacillation, yes, but so far the Chinese are stealing our technologies and recruiting our scientists, and not vice versa! Another thing is that we buy their products, so this is the market - it's stupidly cheaper there than anyone else!

The account is cheaper. They say that clothes in Russia can rise in price by up to 40% due to problems with production in China.

[Cosm22]

Who stole something from China, Mr. Zyablitsev?
Isn't it from Russia?
Would you like to boast of Russia's achievements in this area? Publicly? Enlighten us fools?
China launched the SD-1 solid propellant engine back in August 2019. Next year, it is planned to launch the SD-3 launch vehicle, which will add 1,5 tons to the SSO.
As for Russia, we cannot even make a mediocre TTU. However, the USSR and the TTU have always had problems.

[Finches]

There are many Jewish, Ukrainian and Anglo-Saxon lawyers on VO, now a Chinese lawyer has appeared!

I don't want to enter into a discussion, but China never had a rocket-industrial complex as such until ... 91, when after the collapse of the USSR, Soviet factories, design bureaus and research institutes of the rocket and space industry remained on the territory of Ukraine. So, after that, the Chinese rushed to buy from Ukraine the technical documentation for Soviet developments in the field of space, in particular, for the RD-120 rocket engine .... Plus intensive industrial espionage, the recruitment of our specialists, etc.

[Cosm22]

In essence, the topic has something to say? Do you have enough knowledge?
Or do the big stars on the shoulder straps prevent you from discussing with the elder?

[Cosm22]

Yes. I liked the supplement.
What does the RD-120 LPRE have to do with solid propellants?
And what does "recruiting our specialists" have to do with the creation of solid propellants? If our specialists themselves are not averse to recruiting someone, because this Temka is lame in Russia on both legs?

[Finches]

This is as an example - everything that China has today is not Chinese, if so it is more understandable - yes, they can and do a lot today, but they are not! And about the solid fuel engine - done, well done! How did you do it? Let's take a look! And so, the first work of the Yuzhnoye design bureau in the field of creating solid propellant engines was zapilin back in 1963 ...

[Cosm22]

"They are not them" is demagoguery. What's whose - it's difficult to figure out if you go into the jungle of history. You shouldn't go there unnecessarily. Otherwise, it will become clear by chance that without von Braun there would be no royal "seven" or "Saturn-5". Or the one that the entire world cosmonautics originates from the Chinese prehistoric powder rackets.
What is important today is in fact. Made with hands and head, not tongue. Heavy LV, spacecraft, lunar rovers, OS, spacecraft and probes. And in fact, Russia cannot compete with China in all these areas. And what difference does it make now who stole the club from whom?
If the first two steps in the world space ranking are irrevocably lost for Russia?

[Finches]

It's just that there is also a Chinese myth, but economically they are undoubtedly stronger and decently ahead of us on many issues - because they managed to avoid the collapse of the economy, industry, country ... "totalitarian" regime! But that is another story!

Quote: NDR-791

"It is made from a single piece of the finest black marble! -

this is not the case for heavy-duty solid propellants

The propellant mixture in SRB consists of ammonium perchlorate (oxidant, 69,6% by weight), aluminum (fuel, 16%), iron oxide (catalyst, 0,4%), polymer (binder mixture together, 12,04%) and an epoxy hardener (1,96%). The propellant has a perforation in the center 11-pointed star in the segment the front of the engine and double taper truncated-perforation in each of the following segments and nose
This configuration (combustion area) provides high thrust on ignition and then reduces thrust by about a third 50 seconds after lift-off to prevent vehicle overload during maximum acceleration.
SRBs are used as matched pairs and each consists of four rocket engine solid propellant charge segments. Pairs are matched by loading each of the four engine segments in pairs from the same batches of propellant componentsTo minimize any thrust imbalance... The segmented housing design maximizes manufacturing flexibility and ease of transportation and handling. Each segment is delivered to the launch site in a heavy-duty rail car with a special coating

it makes sense to waggle and make one big checker of solid fuel, there is not any.

If the Chinese have a ready-made working technology for manufacturing high-quality and powerful solid-fuel engines, in large quantities and at a low cost, then this is very very bad news for the United States.
China can use this to dramatically increase the number of its strategic nuclear forces. By the way, what are they actively doing now?
For ICBMs, a solid-propellant carrier is just what you need.

For space and manned projects, liquid-propellant rockets are quite suitable.

Well, that's how it will be applied in reality, it will be clear whether the engine is pulling or not. The WS-15s have also been declared superior to the "prototype". Then they announced that all the problems were fixed. But in reality there is still no final version of the product ..... This is not schadenfreude.

they simply cannot guess and repeat all technological methods. in addition, some of the materials they use are also not absolutely identical to ours. we recently tested the components of their products for technological quality. yes, close to our components, but not identical. Now imagine - one component falls short, the other, the third. as a result, the resource of the final product will be lower, the probability of failure is higher, and the characteristics of the entire product are somewhat worse. this is if you do not go into the scientific and technical subtleties.

It is noted that this development is not the only one; the corporation is currently developing a new five-section rocket engine with a diameter of 3,5 meters with a maximum thrust of more than one thousand tons. At the same time, a three-section solid-propellant rocket engine with a diameter of 3,2 meters is already ready. Its thrust is unnamed, but it is said to be the "most powerful" rocket engine in China.

The photo shows one of the sections, either a 3,5-meter or 3,2-meter Chinese turbojet engine. Presumably the sections will overlap one after the other with a common nozzle at the end.


True, while the most powerful TTRD are the Space Shuttle boosters / 1400 tons of thrust /. Boeing is developing accelerators for SLS based on them.


By the way, they are also made sectional. / photo from mission Artemis /

[Knell wardenheart]

As far as I understand, solid propellants are more interesting from the point of view of the military than from the point of view of scientific and practical space exploration. Solid propellants and rockets on them cannot be called the pinnacle of space technology, although there is still a certain potential in them - but this is precisely what auxiliary resources for classical rocket engines. This direction has been studied quite well by the USSR-USA in order to present certain boundaries of its capabilities.
I do not see a special "triumph of will" in this statement of the Chinese - they tend to inflate every success to epic proportions. This is most likely a classic example.

Solid propellants and rockets on them cannot be called the pinnacle of space technologies, although there is still a certain potential in them - but this is precisely what auxiliary resources for classical rocket engines. This direction has been quite well studied even by the USSR-USA.

The Union was able to create a comparable engine just before disintegration. And then there were dances with the bulava.

[evgen1221]

I'm not surprised that quantity becomes quality if they are engaged in business and not in manilovism. Well, since about 100 mines for the IBR are being prepared, then most likely the engines for such a horde are available and worked out and they are producing and there are reserves for the future.

[mark1]

The engine, of course, is not "the most powerful in the world" - the most powerful was the first stage of the Shuttle - 1300 tons, and besides, it is reusable (in the sense of the case). but nevertheless the progress is significant (however, the TTRD is very "dirty")
