Actually I'm not currently flying behind a Rotary, although I'd love
to be!
Keith, don't take my misgiving's of your test as a lack of faith in
the Rotary.
I believe that it is the best alternative engine we've got and I do
plan to
fly behind one in the future. However, I won't be flying behind it
because it
will fly at any power setting after loosing its coolant. I believe
in it because
it has the best power to weight ratio of any alternative engine out
there, I believe
in it because it is compact, it is cheap, and it is robust. If I was
shopping for
an alternative engine, seeing that a Rotary can run for several minutes
before it pack's it in would be interesting but not the factor which
would swing
me to go Rotary. As you've stated most alternative engines [w/ the
exception
of some Subee's, Vw and Corvair] are water cooled. This means that each
would need a properly designed cooling system, I believe this should be
approached from a proper design/clean sheet perspective. If you design
an installation which can't cool the engine and you blow the engine,
your
out the cost of the engine, possible damage to the airframe as well as
needing to re-design the cooling system, not to mention the lost flying.
The same goes for oil coolers, you don't plan to use a small cooler and
'see how it goes' then get a larger one when it doesn't [ as well as
rebuild
your engine] and test again?
It's also worth noting that I live in an area which is flat, open
and has few tree's
We have a road every 1-2 miles as its all farm land. Landing a
airplane on
a gravel road is a non-event.
Trust me, I have complete faith that the Rotary is the 'right' engine,
I just don't think your going at this the correct way, and I'd hate
to see the Rotary's reputation tarnished due to someone's
careless 'live' testing. Esp since I plan to start producing
components for the rotary and its installation's in the near
future.
If you want to do a proper test, go buy a subee and do
the same test side by side. You'd noted that the all the other engines
wouldn't last a minute w/ no coolant, can you back this up w/
test data? Another thing is, the test should
show how much power each engine is producing. An idling
engine is useless even if it can run for days w/out any coolant.
It's just taking you to the scene of the crash..
Again, I'd ask you to do this test before hand so you know the
results. My wife works for a lawyer and it's been said, don't
ask a question you don't already know the answer to [in court]
why do you think this is? No-one wants to get thrown
off balance by an answer they weren't expecting.
Don't do a live demonstration, to which you don't know
the absolute answers to. You'll just end up doing more harm
than good.
Don't miss the forest for the trees.

The fact that the rotary will run for some time after a coolant loss is
profoundly significant, but to make this feature the main purpose of a
demonstration to failure is to forfeit the opportunity to make other
more important points. Safety and reliability have already been
established by the flying community so the most important objectives now
are to breed familiarity by explaing how the rotary operates and
emphasize how ridiculously low the comparative cost of installing and
operating a rotary engine really is. Builder acceptance of the rotary
has been thwarted because of two issues: the technology of the rotary is
mysterious and, even though many are flying, we have not yet identified
a complete package that builders could easily copy -- we are,
individually, engineering solutions for our own use. Homebuilt aircraft
today are mostly kit-built and those builders want a proven FWF package
that installs with numbered instructions. In an earlier post I wrote
that the most effective demo would be to run the engine without coolant
until it either quit or an impressive run time was proven and an
overhaul necessary - then rebuild the engine overnight and run the
engine the next day. The details of the rebuild would be explored, the
damaged parts displayed and the cost of replacement parts discussed. The
greater purpose then, of running a robust engine to failure, would be to
reveal the ease of rebuilding, even at a remote airport, and
dramatically show the outstanding cost disparity between the rotary and
any other engine. This is a demo that I intend to organize for SnF
through the Association of Rotary Powered Aircraft -- it may even happen
this year. OSH may be mecca but a Florida demo will make news in all the
aviation publications and provide us with show materials at SnF until
OSH is possible.
