Nigel,
Where do you find the time.
Don't you just hate paying that much for carbon? Disgusting, isn't it.
It is great stuff.
I assisted our local engineering college at the University of Central
Florida with some senior design project supervision and we got the
carbon donated. The young engineering students didn't understand....
Regards,
Bud

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
