If water ice floats, wouldn’t it not clog the lines until you run out of propellant, in which case the clog is moot?
I was under impression that they pressurize tanks by pure oxygen
That was my impression as well. I wish I could figure out where people are getting the idea that they are using combustion exhaust to pressurize the tanks. Seems like a weird idea to me.
CO2 will froze and sink in LOX tank, water ice will float. SO both clog the lines. I was under impression that they pressurize tanks by pure oxygen.
