More Oxygen or a Hybrid

[saladtossser]

does anyone know which is mre powerful, a metal cannon with pure oxygen or a metal hybrid?

[spudshot]

well, if you want to live to shoot it again a metal hybrid, but still you'd want to get high pressure metal, hardware store stuff is sometimes not the greatest.

and i dont think just oxygen would ignite, wouldnt you need a fuel to start it, rather than just a spark?

[PCGUY]

Pure oxygen needs to be mixed with something to ignite. I say go hybrid since O2 hasn't been played with much and hybrids are plenty strong.

i knew i needed fuel, what if i gave just enoug oxygen so it would fire safely and be somewhat fully automatic, without open a endcap

[spudshot]

you'd still need to open the endcap because the fumes will still be in the chamber, and O2 isnt played with much so i wouldnt try to find how much is "safe" to fire

The main issue with using a O2 enriched atmosphere is that without the nitrogen to slow the flame front, it reaches super-sonic speeds much easier. That is, your mixture detonates.
I would not suggest being near a launcher, made of any material what so ever, if this happens.

[saladtossser]

all i want is "artifical air" without using other useless gases. and wont the fumes be somewhat vented when the projectileis shot?

[spudshot]

what useless gasses? without the nitrogen in the air acting as a buffer for the fuel (to slow it down) our launchers would most likely detonate without adding everything else
