wolfy9005 Posted February 4, 2009 Posted February 4, 2009 Does anyone have any experience making these? I saw one on mythbusters, where they used salami(yeh, i know) and nitrous oxide as the fuel. They also made one using nitrous again, but this time paraffin + carbon(charcoal) as the fuel. Anyone who saw the episode will know im not just making it all up . Now, does anyone know if a paintball air cannister would be worth using to supply the oxidizer(n2o)? Are their lighter alternatives out there? Ideally i'd want to get the system running in a bench test first, but that wont be for a few more months(moving to a rural area, so might be able to play around with some rockets). Any info is appreciated.
Miech Posted February 4, 2009 Posted February 4, 2009 (edited) I think there is just pressurized air or nitrogen gas in a paintball air cannister, but I could be wrong. Where I live people often make hybrid rockets using small cartridges of N2O used for making whipped cream. There is about 8 grams in such a thing, and that's enough to get a 3/4" rocket about 450 feet high. Anything combustible will do as fuel, ranging from pieces of paper to pressed sawdust/parafin mixtures. I saw that Mythbusters episode, and hope hour rocket will fly better than that one . Edit: I meant something like this: http://www.aeroconsystems.com/motors/Screa...er/screamer.htm With some effort and a lathe you could easily save those 85 dollars and make one yourself.

andyboy Posted February 4, 2009 Posted February 4, 2009 http://www.aeroconsystems.com/motors/Screa...er/screamer.htm That rocket is wicked, I would love to have some of those, the price-tag is outrageous though. Probably could make them myself but I just don't have the time, to many projects to little time. Story of my life.
BigBang Posted February 5, 2009 Posted February 5, 2009 Haha those little buggers cook! I think the N2O paintball tanks are kinda heavy, or kinda expensive. Your best bet would be to check out sky ripper systems, they have some nice motors. Todd's motors are simple, so you should be able to make your own if you get a feel for how his are made. Good luck mate, hybrids are a pain in the butt to get working.
