Looking at the Brayton Cycle Star Rotor in the link above I had a thought.
Would that same idea be workable with a modified Wankel rotary?
Just thinking out loud, use one rotor as a dedicated compressor and the other rotor as a dedicated expander. Like the Star Rotor design there would be a burner/combustor connecting the two rotors. I'm thinking you'll need to add some more ports to each housing yielding (I think) two compressions/expansions per rotor revolution. The primary advantages (I think) would be eliminating the large temp differences between the combustion and intake side of the rotors. The burner (theoretically) could be optimized for more complete combustion possibly improving specific fuel consumption and it may even make it a multi-fuel engine since rotor shape and ignition timing are no longer issues.
Anyone know if this or something similar has been tried?
Any thoughts on how or if it could even work?
