Subject: [FlyRotary] Re: 2.85 redrive
All this talk about 2.85 gear boxes, getting higher into the
power curve,
improving cliumb performance, etc, is really
interesting. Since 3 of my 6
initial reasons for going rotary were
reliability, I'm wondering what running
at these higher power levels is
going to do in that regard.
Hi
Marv,
I think it's
extremely unlikely that anyone will have a catastrophic failure of a NA
rotary below 8000 rpm. Now if you turbo it, all bets are
off. This is one of the reasons I no longer run a turbo on the
plane. I can afford to blow the FD engine, and AAA will tow it back
to my house.
You are correct about
wear though, but you have to decide what you want. I want a toy, that
makes people say "Holy S***" every time I take off. Even if it
"only" lasts 1000 hours before it wears out, that's 30 years of flying for
me. The symptoms of a worn out engine are pretty benign, so when
the time comes, I just rebuild it.
Cheers,
Rusty (anybody need a
turbo? anybody at all...
<g>)
Why....do you have
another turbo? I was considering adding one primarily for the benefit of
muffling the exhaust. I was impressed when I heard John Slade's engine running
with the turbo. Very quiet. Possibly because the turbo muffles the
exhaust, and then the prop finishes the job? Paul
