Hi Nigel,
I should say =AB Master Nigel =BB, really Best-in-Class!
Assuming there is few hundreds of Europa flying word wide, I thing you
have
a market for it.
Otherwise, will you loan the mold or at least share the way to build it?

Bud,
A fascinating article - thanks. It would seem that I have spent the last
God
knows how many years researching the same data as you (mostly 1940's and
50's NACA papers) and come up with much the same conclusions regarding
cooling and cooling drag reduction. By a curious coincidence, I have
been
busy this weekend buried in my workshop - laminating. Compare the
results,
hot-out-of-the-mould, with the computer generated cowl design on page 16
of
your report. My design concepts would all appear to have come out of
your
"Lets's get radical" section!
Keep up the good work.
Nigel

Ken and Graham,
I've attached my modifications and techniques briefing used for Europa
Cooling with the XS cowl which written up in the Europa Flyer .
If I do say so myself, I never have cooling issues in Florida at 95
degree
summer days using 50/50 Anitifreeze. Judging by the calls and email
success
stories, these simple techniques work pretty much world wide.
References for further study are at the end of the document.
Those who have followed these techniques with a stock cowl have no
problems
cooling especially with the trigear. In fact it gets a bit too cool in
cooler climates and this is with no modifications to the existing cowl,
only
treating the airflow around the coolers.
I have worked these issues over the last six years and we just finished
three more aircraft at the shop, all Rotax and we reworked a clients Jab
3300, and all the Rotax's have no cooling issues and the Jab is
tolerable
except taxi times must be short, 10 or 15 minutes max or it gets a bit
too
hot for a takeoff on a summer day.
I'll do another briefing/article on the Jabiru before long.
Call or email me at the office in Florida below if you have need of more
specifics or are having problems getting the references on line.
Regards,
Bud Yerly
