REFLECTOR: MUSCLE PLANES

[Al Gietzen]

Tom;

 

I noted that you didn't ask about the rotary, but consider that it
eliminates all those pistons, connecting rods, valves, rocker arms, push
rods, etc., with their reciprocal motion.  Comes stock with two plugs per
rotor and normal setup is with two injectors per rotor for redundancy.  A
normally aspirated 3-rotor with 2.17 to 1 reduction gets you started at
about 265 hp (loafing), at a weight under that of an IO540.  If you want
more power go to 3.5 : 1 reduction and get about 320 hp for just a few lbs
more in the cooling system.  Add a turbo charger and some porting, and go to
600 hp, but only if you want to win at Reno.

 

My 'all up' (prop not included) NA installation is about 420 lbs wet.  Total
cost for the fairly highly customized installation is about $23,000.  Runs
best on mogas, a buck and a half, or so, less than Avgas, but is also quite
happy with avgas.  It fits into a cowl that is more compact than needed for
an IO360 (mine is on an SE RG).  I'm quite happy with the package, except
for some glitches with the electronic ECU which apparently wasn't designed
for long runs from panel to engine, in a composite airframe subject to
electrical noise; but I'm confident of getting that resolved.
