Hi Paul Just read your article about the rotary engined aircraft in
SAAA Airsport. Your comment “automotive piston engines are not
designed for aircraft power levels and should not be used” is
garbage. Have you not read how chev V8’s are tested. It is to a much
higher standard than any lycoming or continental. We have an RV6
with a V8 out of a car in it and have had so far 520 hours trouble
free flight.

Got any pictures?
what does it weigh? What is the displacement? What does the cooling
system weigh? What does the gear box weigh and who made it? What RPM
do you fly it at? What is the max HP rating? What is the max weight
of the aircraft it is in?
A steam engine will fly :-) Yes a V8 will fly for awhile if you run
it at a low enough power level. Yes they will run for 200,000 miles
in a car at a typical 50 HP level. An aircraft engine runs at duty
cycle level typical of an over the road diesel truck engine weighing
up to 2000 pounds.
Obviously your not an engineer :-) Did you learn any physics in your
Oz high school? :-)
Nor have you studied the history of the aircraft.
Samuel Pierpont Langley chose a Stephen M. Balzerr rotary radial
piston engine for high power to weight ratio while the Wright
brothers designed and built their own high power to weight ratio
engine. First piston engine with an aluminum crank case. The rotary
radial piston engine went on to dominate WW I.
This Kitplanes TTC record article illustrates the high power to
weight ratio advantage of the Wankel. The record will not be
bettered except with another Wankel or this one running at a higher
boost with a better prop.
I had to rescan this at a lower resolution the the first exceeded the
max email size.

This was fascinating !!!
Thanks Paul for posting this PEARL.
And many thanks for your very valuable insight that I have followed for years in the
search for a dream. It has been invaluable given that I have NO engineering
education. (I am a physician).
Crook, you started me on this path when you were flying rotaries WITH carburetors.
I still have your answers to my questions. You don’t know how much I did appreciated
these.
