Anhydrous Isopropanol

Post questions and info about combustion (flammable vapor) powered launchers here. This includes discussion about fuels, ratios, ignition systems and anything else relevant to launchers powered by igniting things like hairspray or propane.

How many people have tried using Anhydrous Isopropyl Alcohol as a fuel and what were the results? I'm not talking about the 90% stuff but the stuff that says "not less than 99%".

Only one local pharmacy carries it at $4 a bottle, but using a hand-pump aerosol can I have seen up to 30% better performance over aquanet and other common fuels. Plus, no chamber residue!

And what are these common fuels that you speak of?

and how did you measure 30 percent?

Anyways, yes, I have tried alcohol as a fuel and it worked fine, but I prefer propane.

Not better than propane but other alcohol-based fuels that come in a can. All the rest are watered down and they show.
