| Subject: | Brain fart: Pics of the dye flow testing. |
No, that's not it. I guess I didn't push send after loading the pics.
I'll try again.
First pic: Note the recirculation zone behind the PF muffler without the
fairing. Lotsa drag
Second pic: This is the second version of the fairing that goes behind the
muffler. This moved the turbulence to the space between the nose gear fairing
and the muffler fairing.
Third pic: There have been a whole slew of tests between second pic and this
one. I tried three different locations for the angle of the fairing to the
airstream. Note, this version doesn't have the nose gear fairing. Removing the
fairing hurt CHTs, so, I went looking for a fix without increasing drag. The
NACA ducts had no affect on CHTs, BUT, they gave me a couple of knots. I think
accelerating the airflow in the exit ramp reduced the difference between the
cooling air speed and free stream airspeed, thereby reducing drag.
The LoPresti nose bowl (sorry AJ) uses a very large NACA duct on one side to
improve cooling. This would be fine, but, the ramp is too short for it's
height. This would work better if the ramp were 4 feet long for the height of
the ramp. "I think" the air flow is too slow for that large of a ramp. This
hurts drag.
I have an idea for a test cowling that may fix the cooling problem without
hurting cooling drag. Composite Dave will start working on it after a few
other projects are finished.

Right now, this is what I have. Nothing hard (i.e., no deposit) decisions made.

RJ, can you post my offer for a reduced price on the cowling to the 'other'
forum. I'm not on it. Thanks.

Sure! Happy to!
What's the deal? Why can't you just go on and post?

Gary,
If this applies to a traveler, I might be interested.

Sorry Kevin. It only fits the Tiger. If someone bought the Tiger Cowling from
me, I'd get started on a Cheetah/Traveler version.
