2R1 airfoil
« on: January 03, 2002, 05:33:00 AM »
Hi

The 109 used from the F on the 2R1 airfoil. Does someone have data how it looks like? (coordinates, wind tunnel tests ...)

thx

2R1 airfoil

I have been wondering same thing; maybe it is some kind of luftwaffe marking? Anyway, according to Jukka Raunio's "Lentäjän Näkökulma II" the root profile was modified NACA 2315 and tip profile was modified NACA 2309.

The 2R1 is a NACA designation.  Exactly what it means, I don't know, but here's the coordinates for the 109.
