Well its been raining almost all week and there will be a lot more rain for the
entire week to come... the airfield is now a great lake and the carrots have
rotted in the ground; so that means theres nothing to do but sit at the console
desk and drive the computer to crunch more numbers with a more resolved model
while mixing Ballantines and coffee into the one cup... what a brilliant little
aircraft!!

Cool images. Not that I fully understand what is good or bad but I assume that
a sharp change of velocity is not so good. Is then all the blue around scoops
and openings bad?
So this weekend went to 9FL1 Fly-In breakfast with EU. Being the only Europa most
people have ever seen it was always surrounded by people :)
Nice flight. Great speeds (people making comments on the radio on how fast I was
going for a 912 powered airplane). Grass runway, a bit bumpy, takeoff was interesting
but all ok.

2/28
Some pics from our local 32nd annual river ice fly-in yesterday in Ottawa, C
anada. Sadly this year skiis only due to organiser-illness, so low passes on
ly. AOA lectrical connections now appear to be solid, what a great tool to m
anage energy over the runway. Luv my lil=99bird in the winter - great
performance imho, ~135knot at less than 5gal/hr.

That aircraft looks so good Peter; well done on its presentation! Are those pieces
of cardboard at the radiators to help maintain engine temps?
Chris, variations in colour indicate changes in airspeed velocity; there is a scale
if you zoom in and the velocity applied is 51m/s or 100kt; low velocity is
not necessarily a bad thing however its an indication of turbulence induced
drag around exit vent openings and rearward of aft surfaces as slower and faster
moving air rejoin, getting these two velocity streams to combine back together
more smoothly is a desirable outcome... one of my test pilots has just suggested
trying vortex generators; will be interesting to see if that has any desirable
affect... will be interesting to see just how much total drag can be reduced
and how that might be achieved!!
For the technical minded the test was carried out with theta, beta and delta all
set at zero, alpha is equal to angle of incidence. Returned output forces NM
(x) -587 (y) +4424. (Results are indicative only and may vary substantially between
individual built aircraft)
