Waterfall and Smokescreen for an Alumazine Plume.

 Share

Recommended Posts

Hello,

I'm working on an alumazine plume for Restock Waterfall Expansion as I figured that I'd contribute to @AtomicTech's project seeing as the Alumazine plume for the mod still hasn't been finished. I know that, from a previous thread, that the plume would "quickly precipitate in a silvery residue downrange. So, I imagine it would be "sooty" and smoky as all heck, closer to an SRB than an LRPE." (Thanks @DDE :grin:). How would I go about using smoke screen to add the slivery residue and soot to the existing plume?

You see, the problem I didn't mention is that these exhaust characteristics were a sign of failure and underperformance. Alumizine was abandoned by both the US and Soviets. It only really worked when paired with ClF5 instead of NTO, which I believe the US fired but the Soviets nevwr combined (the same SLBM upgrade program tried them separately).

Oh! What's your source? I'd love to read more about it!

"Then, once the fuel is in the motor — and I won't go into the problem of designing an injector which will disperse a gel properly — there's the problem of burning the aluminum. Unless the chamber temperature is well above the melting point of aluminum oxide (about 2050°) or, preferably above the considerably higher temperature at which it decomposes, the aluminum particle will simply coat itself with a layer of solid or liquid alumina, and refuse to burn to completion. When burned with N2O4 the chamber temperature is just about high enough to burn an aluminized gel properly. It's highly probable that combustion with nitric acid would be marginal, with a chamber temperature not quite high enough to make the metal burn to completion. (With a halogen oxidizer, such as ClF3, this particular problem doesn't arise, since AlF3 is a gas at the temperatures we're talking 
about.) And, naturally, the dense clouds of solid Al2O3 resulting from the combustion of an aluminized gel leave a very conspicuous exhaust 
trail."

John D. Clarke, Ignition! from about p. 183 onwards
