Hadn't thought of that, although as a previous poster suggested, a Roots blower is a direct-drive supercharger that's more or less positive displacement, and...
That leaves sealing the bearings from the post combustor temps and needing something to build the rotors from. I'm quite sure that this can be done, but I do...
