All the GenAv duct attempts I could dig up wound up ditching
the duct and going back to a prop, some after significant time and
expense.
Hi
Donald,
Thanks for the
comments. I've also noticed an huge lack of examples of GA ducted fans,
and that usually tells you something important :-)
I've been led to believe
that ducted fans had some thrust advantages at low airspeeds, but that
they generally wouldn't work well at normal GA type cruise speeds. Since a
gyrocopter is a slow aircraft, that lives for thrust, it just seems like it
would possible work. On the other hand, it's probably worth noting that
there aren't any fan units out there for Rotax engines on gyros, or pusher
ultralights for that matter.
Cheers,
Rusty
