REFLECTOR: Oil cooler exit

[steve korney]

Barry... Sorry I didn't add the following note with the picture...

Then, maybe you won't need the rear cooler at all...


Best... Steve

Barry,

I was just staring at that sub-project today.  The traditional solution is a
"reverse NACA", in which the cut flap of cowl skin is bent in to form a
"ramp" for the exiting air.  The ones I have seen didn't have anything
sticking out beyond the original cowl surface.

(My Catto prop is to be delivered this Saturday, and my panel is coming from
SteinAir next week, so I'll be out of excuses and have to finish this
project!!)

Hello
I'm exiting my engine compartment oil cooler air thru the bottom cowl.
Do I need to make a scoop for the exiting air on the bottom cowl to flow
out or just a hole for it to exit thru?

Thank You
Barry
