The claim in this article is that the motors use 70% hydrogen peroxide with alcohol (it does not say which one), without a catalyst. I have not found any explanation of the alcohol's purpose, or whether it is oxidzed in the process.
- thescriptkiddie 6y agoIt could be a "mixed monopropellant". The H2O2 decomposes to H2O + O2, presumably at high enough temperature to react the O2 with the alcohol (probably ethanol or methanol). As an added benefit your exhaust gas is no longer oxygen-rich, which can cause problems.
- skykooler 6y agoIt's confusing, because at the top they say "This rockets don't use a catalyst" but further down the page they say "all this thanks to our proprietary formula of the penta metallic catalyst pack invented by Juan Manuel Lozano Gallegos from TAM." (Side note: I saw that name and wondered where I had seen it before; turns out he's the guy Popular Science wrote about fifteen years ago for building his own peroxide-powered jetpack.)
- Gravityloss 6y agoMaybe they meant the catalyst is not a liquid catalyst that is consumed.
