One idea is to design the exhaust expander into the 2 rotor housing on the 13B, giving us a one rotor with extra benefits. A design challenge I know. As a Dreamer, i was feeling left out!

   A few months back, Paul you spoke of a Radial Rotary Engine Copy, perhaps the Jugs in that Radial could use Exhaust Expander concept ???

   I don't understand what you have in mind.

Paul, a few months back you spoke of using Mazda Rotary Engines two, three engines) to create the Jugs of a Radial Engines much like past engines i.e. Corsairs R-2800.  Suggesting a two Jug (Mazda Rotary) using Exhaust Expander concept when one engine is idle, it feeds its exhaust into the other Rotary Engine to recover work from expanding gases, and later starting up that second engine for higher HP output as needed. The exhaust gas would drive the second Jug if the term Jug is correct. Treat the second Rotary Engine as a Turbo Charger from the exhaust gas, recovering energy from the idle Jug.

That was just wild speculation. I am trying to focus on practical apps now. I suspect anything over 1000 HP will be done with turbo props.
The TTC configuration hopefully will cut into that cat.
