Paul,

Just curious. Would a turbo-compounding turbine for a rotary engine
look like the drawing on the website, i.e., as large in diameter as
the engine itself, or would it look more like the turbine from the
R-3350?

By the way, my father chuckled when I showed him the image of the
turbo-compounded Allison. He told me that Bell was looking to a 5
bladed prop to harness all that power. Too bad the XP-63H was never
built.

A R3350 turbine might work as is. It is about the right diameter.
