Barney, thanks for moving the tree - made it easy
for me to drive to church in High Springs later on that morning.
Tracy & Laura, thanks (times 10) for the
great gathering of rotary aircraft & "engineers", hospitality, food,
sleeping & other necessary accomodations - & great weather!
I left High Springs about 1:40 and was home just
south of Beaumont , TX, 10+50 later then set my clock to Central time & it
only took me 9:50 (?) - hope the flyers got through the low crud &
rain in the Fl panhandle.
All the way home I was mentally designing
(fantasizing) of getting a "blank" cowl from Van's with NO HOLES in the front,
then doing many interative "positionings" of engine and components "under the
hood" until I decided where it all would be, THEN cutting holes for the 2 A/C
core-rads, oil cooler, and engine air intake so as to get the air inlets
"perfect". Even thinking of individual P-51 style inlet/outlets side
by side in the bottom of the engine cowl - with outlets just below the bottom
line of the firewall, but not necessarily that far back. Let's see: No
further back than 1.5 times the prop chord . . . . . . . (where are all those
"theory" e-mails I printed off 3 years ago from PL's list?)
Bernie Kerr, after Ed's masterful analysis of DIE,
I can see real possibilities for an experienced J-58 Blackbird engine guy with
"skunkworks" level of skills and analytical insight - taking on the "external
diffusion" and "direction of airflow behind the prop" to get stagnation points
for max pressure and correct vectors for orientation of inlet geometry for rads,
oil cooler, and, especially, the engine air induction probe right
behind the prop to get maximum pressure boost in Manifold Pressure (Lancairs
getting 2 to 4 inches??!!) without using a turbo - kind of DIE from the 2 prop
blades into the air inlet for the intake manifold.
Was I dozing and dreaming at the wheel driving home
or did I really think about all that stuff? Was the rotary fly in a true
mind altering event? (or mind boggling?)
Wait a minute: What is the basic "calculus"
for homebuilding? Something like this: Time between "now"
and "first flight" is a direct exponential cubed relationship to the number of
mods to (deviations from) the std plans? Or, as summarized by someone in
the Pentagon, "Better is the worst enemy of good?" . . . . .
I had a great time. Thanks again Tracy and
Laura and all who came and shared and took off engine cowls and answered endless
questions.

Thanxs again Tracy and Laura, great fly
in.
Never did like flying commercial.
Got up at 2 am at Tracy's to drive to Orlando
( 3 hour drive) for an early flight back.
2:05 am. Tree down on 50th by Tracy's, able
to get the top off the tree and drive around.
Made airport promptly, got on big plane with lots
of kids crying and screaming.
Encountered serious turbulence halfway to
Cincinnati, lots of kids crying (this time with a good reason tho).
Guy sitting next to me gets airsick and leaves a
deposit in his plastic head phone bag.
All the while stuck in a seat that had less room
than a C 150.
Working late tonite on the plane.
