Hello again!: I guess you may know this Heinkel concept, from the Max Bentele's SAE book: 'Engine revolutions', that about Wankel, concludes the right way is stratified charge.

Italians used the idea of an internal combustion engine moving the compressor stage of a turbine, then something as the afterburner of a jet engine, in a Caproni-Campini airplane, quite massive, and never achieving the desired speed goal, but Bentele claimed the design of HeS 50 would yield a 50% fuel economy respect to their contemporary turbines.

Perhaps a Wankel adding the coolant heat and exhaust heat to the overall way out jet, the 'ducted fan' walls acting as radiator, may give some good results. Who knows?

Thanks, best regards, + Salut

CW, John Deere and Rotary Power International spent  hundreds of millions  of US Dollars
and never got  stratified charge  to work in the rotary.

They studied turbo compound as and after thought and it showed great promise but they never
built any hardware to test it.  They predicted 80 HP of free additional power
from the same fuel on a Mazda engine. No money left.

The Napier Nomad is a copy of the He s 50. Later patented by Rolls Royce
in 2011 but with a Wankel and not a piston engine.

Check out APPENDIX C on page 156 attached.

Simon Saba will test it someday :-)
