Subject: [FlyRotary] Re: 100 hp
options.
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
Hi Tony,
I am attaching the data sheet of
my One-Rotor converion.
The prove of principle version has run
5hrs. primarily for temperature cycles. The prototype version, which will be
flyable, is in the works right now. I will fly the prototype in my plane,
hopefully sometime later this year.
I have no real plans yet of how to make it
available to others.
