NightHawkInLight Posted March 23, 2013 Share Posted March 23, 2013 I thought this video was pretty cool. I've seen plenty of hybrid rockets, but none that doubled the actual motor casing as the fuel also, at least not to my knowledge: I like the idea of using the motor casing as the fuel because it gives you the option of continuing to burn the rocket past the critical wall thickness if you just needed to push it extra distance no matter the risk of a rupture. Not like I'm ever going to fly one to Jupiter and find myself in a situation where that would be necessary, but I like the idea. Link to comment Share on other sites More sharing options...
Nessalco Posted March 23, 2013 Share Posted March 23, 2013 This was first done 15 years ago or so - I forget who pulled it off, but it was widely distributed at the time. These motors are cool demos, but are not even close to flight-worthy. Start running the chamber pressure up where they "should" be and this sort of setup will likely rupture. Also, GOX is not a viable oxidizer for a motor. It is used in some systems to start a N2O hybrid, but not in flight - not enough density.
