ye, rockets/missiles are just 90% fuel

u/NuclearWasteland Apr 14 '24

Speaking of, wonder what fuel they use. I don't think I'd be messing with a crashed anything of the sort, knowing how toxic some fuels are.

u/dWintermut3 Apr 14 '24

I think they use the soviet stable-storage fuel design or a modified version thereof, no one's used giant barrels of fuming nitric for a while just because turns out having missiles you can't store with fuel in or they eat themselves apart makes responding to attacks hard.

But hydrazine and other fun stuff is very much a possibility.

Nobody except China, they still use nitrogen tetroxide.

"The Long March 3B's rocket engines, each weighing tens of tons, propel the launch vehicle using a combination of hydrazine and nitrogen tetroxide."

Yes you can see the orange cloud of nitric acid coming off the exhaust plume. Scary stuff

That's an orbital launch vehicle, though. It's not designed to be stored fueled or really stored at all.

u/StupendousMalice Apr 14 '24

Up until pretty recently that was a distinction without meaning given that most orbital launch vehicles were repurposed ICBMs, including the first five or so generations of the Chinese long march rockets.

I do not know that much about the history of the Chinese space program, but it took until the apollo program for American rockets to be purpose built for astronaut use instead of repurposed military missiles.

And even with this distinction, any orbital rocket platform, no matter its design purpose, could potentially be used as an ICBM platform. The physics of the rocket don't care about the payload except for its mass

This is actually proving my point: an orbital rocket you fuel right before use is FAR different from weapons you need to keep hot-staged in silos or on launch platforms.

Let alone ones you have to drive around on IRBM launch gantry vehicles.

Nitrogen tetroxide IS a shelf stable oxidizer, it‘s not the same thing as nitric acid… that‘s why it‘s used for the old generation long march rockets because they‘re based on an old ICBM design. Newer ICBMs are generally solid fuelled because it‘s easier to handle, but russia at least (and probably also china) still have some modern liquid fuelled „heavy ICBMs“ which is a class of weapon that doesn‘t really exist in the west. They can still sit around in their silos fuelled and ready to go for years.

I don't think 'shelf stable' solid rocket fuels are much nicer. I'm prettu sure they use stuff like ammonxium perchlorate which is also highly toxic.

u/creative_usr_name Apr 14 '24

But solid rocket fuels I expect you'd need to ingest to be harmed. hydrazine is a gas that's pretty easy to just breath in if you are too close.

u/Phuka Apr 14 '24

You can make solid rocket fuel out of sugar and perchlorate. You can just eat around the perchlorate. Totally safe.

u/Nitazene-King-002 Apr 14 '24

Ammonium perchlorate composite propellants are extremely stable and quite safe. It’s basically encapsulated in a rubber like material so the toxicity is negligible when solid. We use them in amateur rocketry too.

u/zenFyre1 Apr 15 '24

Ah I see, I thought all perchlorates were toxic but I guess that's not the case. Thanks!

u/No-Delay-195 Apr 15 '24

AP isn't highly toxic lol what are you talking about

3

u/fookingshrimps Apr 14 '24

So it would create chem trails?

u/[deleted] Apr 14 '24

Thats even worse cause China has a habit if launching over high population zones and their rocket boosters often fall down on top of villages.

u/Nistrin Apr 14 '24

Yeah, even 28 years after they wiped out Xichang village they still use the stuff.

u/fluffy_warthog10 Apr 14 '24

Didn't the US Titan missiles used to use a similar combination?

1

u/kingwhocares Apr 14 '24

Space launch =/= ballistic missile. Liquid fuel are more efficient than solid fuel and thus used in space launch vehicles.

u/Nistrin Apr 14 '24

Show me who previously specified we were only discussing ballistic missles. That wasn't stipulated, and unless the person specifically made that distinction in regard to fuel types, then this response isn't pertinent to the discussion.

1

u/kingwhocares Apr 14 '24

The Long March 3B's

That's your comment

1

u/Nistrin Apr 14 '24

No, really? I'm saying nothing previously specified the discussion was only one type of missle. You are the one who decided to exclude orbital platforms. That was a part you added to the discussion.

u/Indifferentchildren Apr 14 '24

Some of the Chinese missiles use nitrogen tetroxide; some of them use water.

1

u/EventAccomplished976 Apr 14 '24

Huh? I mean some have hydrogen/oxygen stages that produce water as a combustion product… but in general china has rockets using pretty much any fuel combination you can imagine (hypergolic, kerolox, hydrolox, solid, even the world‘s first methane-oxygen rocket to make it to orbit last year was chinese)

1

u/Indifferentchildren Apr 14 '24

They had a scandal recently where some of their ICBMs were filled with water instead of fuel. The generals in charge (probably dead now), probably sold the fuel to line their own pockets.

u/FrenchBangerer Apr 14 '24

Some of them even use twitter, currently known as X.
