China completes ground test cycle for rocket propulsion

On Monday, Chinese experts successfully conducted the last ground tests of the power plant, which will be equipped with the Changzheng-5 launch vehicle, being created as part of the Chang'e Moon exploration program, RIA reports "News" with reference to the Xinhua News Agency.

Representatives of the state administration of China on science, technology and industry for national defense (SASTIND) noted that these tests have become a good preparation on the eve of the launch of the rocket, which is scheduled for next year. The power plant operates on a non-toxic and environmentally friendly liquefied propellant. With its help, the Changzheng-5 rocket will be able to deliver tons of payload into 14 orbit.

The Chinese moon exploration program has three steps: circling around it - Chang'e-1 and Chang'e-2; landing on the satellite - Chang'e-3 and Chang'e-4; and returning to Earth - "Chang'-5" and Chang'e-Xnumx.

In 2017, China plans to launch the Chang'e-5 satellite from the Wenchang space center, whose mission will be landing on the moon, collecting lunar soil and returning to Earth.

It is worth noting that in December last year, the Chinese Space Technology Association (KOKT) announced plans to transfer carrier rockets to the use of clean energy sources over the next 15 years.

Well done Chinese, they go forward, no matter what, we wanted to see such progress in our country

[Baikonur]

and we wanted to see such progress

So we have no less progress! The whole cosmodrome is under construction (with flaws, but it goes)! Heavy "hangara" is waiting for the start! They have only 14 tons of useful load!
What do you have for pessimism in our direction!
Set aside the talkers!

[NordUral]

Where is he? In the hangar? So there still have not decided on the line. And the table on the East under the Union is being prepared in parallel. So not everything is going smoothly, unfortunately. And just as the cosmodrome itself is being built, under Stalin and the Korolev the entire leadership would either be sitting already or put to the wall. The second is more true.

[Baikonur]

But the thing is coming!
Rogozin (from Putin) Took up for them, really, why is it so late? But more than 100 criminal cases have already been opened!
But the fact that

under Stalin and the Queen, the entire leadership would either be sitting already, or it would be set against the wall. The second is more true.

here I completely agree with you !!!
SHOOT!

[Alexey Boukin]

Big money. Far from Moscow. And most importantly, greed. Here are the three components that prevail on similar construction sites.
And there’s a fourth - confidence in impunity ...

[Skiff_spb]

The only question is what kind of orbit.
Transition is one thing. AND TOTALLY another GSO. 14 tons per GSO is very, very.

[Edvagan]

a pity, but the "heavy" Hangara is not very heavy. And there is not even a concrete conversation about a super-heavy rocket. And our space program, unfortunately, is a set of "wishes" for a period of time, by the end of which no one will be responsible for anything. Alas.

China already has 4 spaceports !!!

[Major Yurik]

We have carriers, the Chinese, too, are glad that the Yankees, as the Chinese newspaper said, have no Xinhua!

[Amurets]

Let's not rejoice early. The Americans, flying on our RD-170; RD-180; NK-33, bring their falcon. On the ground body kit, it works well. But the ground body kit is made for reliability and safety of tests and does not work in such difficult conditions as the flight one. Design engineers know how hard it is. combine the three parameters; reliability-weight-price. Why price? Yes, because some materials cost dozens more than the cost of gold. What is a "body kit" This is a set of units necessary for the engine to work: gas generators, turbo pumps and other units. I don’t know how things are going with a heavy carrier, but the launch pad seems to be just starting, the Americans are going to bring their carrier of the heavy class by 2018.

[MolGro]

successful launches of light and heavy have already passed
So we have long seen! did you happen to be from Mars or in the taiga?

Oh, these Chinese! Everything is in time, however! Plus hard work. And yes, corrupt officials are being shot.

[iliitchitch]

Respect to the Chinese. Slowly but surely digging. They will have the Moon Hare drum on their drum someday.

[Russian]

If not 100%, then 90% are exactly copied from ours, but for the sake of achieving the goal, all means are good.

[dauria]

then 90% are exactly copied from ours,

Somehow they showed a piece of their production ... Clean spacious workshops, young staff. And the rocket is something from us, something from the Americans. And then, "copy a rocket" sounds funny, it's not a physics puzzle to write off. They had an explosion here the other day, and they got into the frame of houses, apartments, random people, soldiers. This, brothers, is no longer China of the 80s with down jackets and thermoses. I would not be surprised if the Chinese will receive the Nobel Prize soon.

Yes, but you see, we have too many multinational people, and while each of them is fighting more attractively, the rest of the world is running in front of us, but we are not standing, not standing at all.

[gudgeon]

Hmmm ... Well done Chinese, but not so long ago, remember? "A new space rocket crashed in China, killing 3 crew members and 150 stokers." And now - that's it, it's not funny already. Soon we ourselves will catch up and overtake China.

[roskot]

Yes, let them fly. And ours will not leave us.

[nomad]

It flies on liquefied propylene - it’s also something that should be made of hydrocarbons. What is its purity? kerosene is also from hydrocarbons. However, for some reason it is not considered environmentally friendly. Maybe someone will explain about propylene!

In general, propylene is an inert chemical. in-va (usually mixtures of two or more components), by means of which excess pressure is created in aerosol containers, which ensures the displacement of the active compound from the package and its dispersion in the environment. For example, chladones are usually 11 (fluorotrichloromethane) and 12 (difluorodichloromethane) , rarely-114 (tetrafluorodichloroethane), 21 (fluorodichloromethane), 22 (difluorochloromethane), 113 (trifluorotrichloroethane), 115 (pentafluorochloroethane). Also propane, butane, isobutane and mixtures thereof, dimethyl ether, etc.

[Cat man null]

Power point works for non-toxic and environmentally friendly liquefied propellant.

PROPELLENTS (from Latin propellens, genitive case propellentis - expelling, pushing) inert chemicalsby means of which overpressure is created in aerosol cans, which ensures the displacement of the active composition from the package and its dispersion in the atmosphere.

There are reasonable doubts that something can fly on this. Author, kill yourself up the wall ..

Rather, this is what it is about:

Propylene (propene) СН2 = СН-СН3 - unsaturated (unsaturated) hydrocarbon of a number of ethylene, combustible gas. A substance with a narcotic effect is stronger than that of ethylene. Hazard class - fourth

Well, yes, safe .. better, heptyl, of course .. but IMHO worse than kerosene ..

[nomad]

We would also switch to propylene. How many are usually observers at the launch. Then he launched a rocket - all at once "sniffed" and it doesn't matter where the rocket flew, why ...

[iskanderik]

China is tearing into space. But on earth it is below the baseboard. People on the verge of starvation. Work for 5 bucks. In large centers, life and on the outskirts - zvizdets.

Salary on Chinese conveyors - 200-300 dollars per
month.
They already bring some production to countries

The smog that enveloped Beijing in the winter of 2012-2013 spurred the government to find a solution to the problem. Authorities have deployed a thousand stations that send measurements of six types of air pollution hourly. The level of PM2,5 microparticles settling in the lungs and causing respiratory diseases in Beijing is three times higher than the standard of the World Health Organization. Richard Muller of Berkeley Earth noted that breathing in this city is like smoking forty cigarettes a day.

What for us such progress? Soon it will be necessary to walk in a gas mask in the forest.

[CT-55_11-9009]

What exact info. From Mossad?

[GoHardLikePutin]

Ndaa, while Russia is at war with its neighbors and our GDP is falling, China is still working and is working. By 2020, China and the United States will probably squeeze us out of space.

[Skiff_spb]

China, too, is not easy in the economy. There already had to devalue - the currency war is in full swing. The euro was also lowered.

And the ruble - they simply did not hold it, because a low rate is beneficial for the country.

Well, the war with the neighbors ... What? So in 2008 there was a war. And what in Ukraine is more a war with ourselves. Ours, of course, go there too, but this is not an open clash of countries.

[GoHardLikePutin]

What is the difference, the longer the war, the worse it will be for our economy and for the ruble, respectively + low oil prices, this will accelerate our growing backlog in space, and everywhere too. But do not compare China with Russia because its economy is 5 times more powerful, 5 times Karl! And even in a crisis, it grows 6% a year, it only takes time to overtake Russia in everything, and the USA too

[asiat_61]

But the ruble - they simply didn’t keep it, because a low exchange rate is beneficial for the country .... What is this about? And the Swiss mean sheep, and they strengthen their currency to their own detriment.

So they will start it not today or tomorrow. Our "Angara" for 14 tons is unknown when it will fly ...

It would be ashamed to demonstrate such blatant illiteracy, and even with "kill against the wall." Battle teapots on the march.

Propellant - this is what the movement reports, within the framework of the missile theme = fuel (+ oxidizer).

A la this: "liquid propellant rocket engines"?

Well, now, as it really is:

Quote: http://neftegaz.ru/news/view/139792

Changzheng-5 engines YF-100 are powered by non-toxic, environmentally friendly fuels.
The developer of the YF-100 liquid-propellant rocket engine with a thrust of 120 tf on components "liquid oxygen - kerosene"Is the Space Motion Technology Research Academy (6th Academy, Xi'an City) as part of the China Space Science and Technology Corporation (CASC).
The YF-100 liquid propellant engine, obviously, uses the experience of creating the RD-120 still created in the USSR.
On the basis of the YF-100 liquid propellant rocket in China, a line of environmentally friendly carriers of the heavy, middle and light class and the entire promising space program is being created, including projects of a manned modular orbital station and lunar exploration by spacecraft of the 3rd generation
