What airfoils has 115" glider Countryman?

[sky_surfer_fra]

Hi all,

is there anybody who knows what airfoils the Countryman has?.
It is a 115" high aspect ratio glider. Plan #2217 from "Model World"
I have a plan of this really nice glider but no idea what airfoils are used.

Thanks and regards,

Tom

I have a book called "Airfoils to Go"
Looks like either a Quabeck, or an Eppler airfoil, maybe even a Gottingen.
Can you give me a chord and max thickness measurement, and I could compare it to what 's in the book.

Thank you Ed.

Wing root is ~15.6% thick, middle ~ 15%, wing tip ~13.5%.


But I have no idea how to give you the chord as I am not sure how to measure this :confused:...
Any hints are truly appreciated.


Regards,

Thomas

Hi Thomas,

The airfoil looks very similar to the Wortmann FX, this site has the section from the full size Standard Cirrus:
