SpudFiles

Hey !

quick question.. Do any of you remember if there is cannons here that work with atmospheric oxy/propane mix ? (open chamber, not hybrids).
I know there probably is, but can't seem to find them now.. Links ?

I'm interested how will the atmospheric oxy/propane mix compare to 4x mix hybrid. Any experience/knowledge on this ?

I don't have any links offhand, but I did build one back in '07, before I joined Spudfiles. The maximum combustion pressure in such a mix can be about 23atm, as opposed to about 8atm for an air/propane mix. This occurs around 3:7 oxy/propane, as predicted by GasEQ (which you really should be using, if you're not already).

Careful DYI, we're being wiretapped...

I did try it (GasEq) but i'm not sure if I got everything correct, could you post a screenshot of any oxy/propane mix, that way I could check if I get same numbers

Just to be sure.. What "problem type" I should use when modeling a combustion cannon or to find the max pressure in closed chamber ?
