"Elbit also makes Wankel rotary powered UAV's."
Paul Lamar
No mention on the Elbit website that they manufacture the Wankels -
Any idea of a source for the engines in the attached photos ??
Roland Friestad
They probably went secret :) They could be from UAV Wankel engines in
the UK.
If you put "UAV wankel engines" in Google they will come up.
The UAV aircraft pictures I took at the Paris air show in 2005.

In a UAV, extending flight duration per pound of fuel burned is
probably at the top of the list. Adding turbo compounding to a
rotary powered UAV seems to be a no-brainer to accomplish this goal.
Paul, you have been looking for someone to develop the technology for
a long time. The UAV industry should have sufficient motivation to
spend the capital needed to develop turbo compounding technology for
the rotary. Perhaps they already have?
Cole Chandler
Could be. They have the success of the Form 1 turbo compound engines
for inspiration.

If not AIXRO could do it and the UAV world, not to mention the
wannabe range extenders, would beat a path to their door. A small
turbo charger and a small gear box is all they need. The thing about
UAV's is a high percentage of the engine power is used to generate
electricity for the electronics package. Just hooking the turbo
charger to a generator would accomplish that. Cheap and simple. That
is essentially what they do in Formula 1.

Hi!:
www.ecotrons.com sells a line of Turbo Compressors and EFIs
for small
size engines, the SAE article by A L London, from the Jan 1954 meeting:
'Free-Piston and Turbine Compound Engine -Status of Development',
contains info about this, but searching inside SAE with the key words:
'Turbo-Compound', would yield many papers, articles and books.
