I intend to build a Zenair CH801 (13B), at the
moment it is not approved by the PFA, my second choice is a CH701. My dilemma is
; to match a rotary to 100hp efficiently would it be best to "make" a single
rotor, run a 13B direct, de-rate a 13B/PSRU or use the Soob EA81 that I
already have.
Hi
Tony,
Welcome to
Flyrotary. We're a pretty civil group here, so fear not :-)
As for your
engine choice, I think the only reasonable Mazda rotary option for 100 HP
is the single rotor. The normal 13B probably won't give you an acceptable
power to weight ratio for only 100 HP. For example, the "normal" installed
weight for a 13B is around 325#, which is a lot for only 100 HP. The good
news is that several folks, including Richard Sohn (on the list) are developing
some promising single rotors.
There are
also some commercially available, smaller rotaries that would be
suitable, but they're expensive, and somewhat
unavailable.
Cheers,
Rusty
