Dumb Question Time--Just scribbling on a paper napkin here, but:
I'm assuming "flash steam" boilers put out more CFM than regular boilers--can anyone confirm/deny that for me?
Assuming flash steam boilers put out more CFM than our more traditional, small, 30-40psi boilers of (unknown to me) CFM, perhaps that would be an option, to run a air/steam "turbine"--be it sourced from the dental industry or elsewhere?
Alternatively, I know there are actual JET engines (burning some type of chemical fuel) in model-scale, flying aircraft. They can certainly handle far more heat than steam would ever produce!
So my (second) question is: are there any actual model fuel-burning TURBINE "prop jet" (i.e., a gas turbine turning a PROPELLER) engines, in the model RC aircraft world?
IF so, I wonder if they could be "driven" by steam/compressed air, instead of by burning fuel inside of them?
Because at least you'd have a realistic set of graduated-sized turbine blades, to take (mechanical?) advantage of the decreasing pressure steam, as it expands, and leaves the engine....
Again, just shots in the dark--please feel free to set me straight--I'm here to learn and, if possible, contribute.
Thanks,
