I think you will find that self pressurizing liquids are a lot more of a pain than you expect. Transfer and the variable pressure with temperature are indeed hassles.At 03:12 AM 1/29/2003 -0500, [EMAIL PROTECTED] wrote:However, we may run into the same problems they have when using nitrous on cars, where a tank heater is required during long runs to keep the vapor pressure up. So, at sufficient flowrates, your 'vapor pressure' is much lower than the steady state value. This may be OK if your fuel pressure can auto-compensate, but be bad if you desire constant pressure, thrust, and fixed mixture ratio.
I'm aware of that. However, a tank heater with thermostat is a simpler and more rugged than a constant pressure system
