Isn't this very similar to the one that brought Mistral's Cherokee test
plane down?
I wonder how it would perform if there were four reinforced 1/2" holes
drilled in the front transition, such that a small amount of exhaust
energy could escape that way, and ram pressure could pull in cool air to
mix with the hot, supersonic exhaust.

Hello All:
I’ve attached a hand sketch for a “simple” muffler for the rotary.
Parts all standard from Burns Stainless Steel (304).
Note there are holes right at the transition outlet flare to ease
pressure at that point.
Inlet has a deflector to force exhaust to exit through multiple holes
in the tailpipe insert.
… let me know your thoughts.
Jeff
