Overall (mm): length 100.0, width 20.0, height 13.71
- Wortmann FX 63-137: F. X. Wortmann (FX series, Stuttgart). Maximum thickness 13.71 % of chord at 30.9 % chord; maximum camber 5.97 % of chord at 53.3 % chord.
- Coordinates from the UIUC Airfoil Coordinates Database (M. Selig, UIUC Applied Aerodynamics Group), file fx63137.dat, titled 'WORTMANN FX 63-137 AIRFOIL'. Thickness and camber are computed by Xem Studio from those points (vertical distance at equal x, linear between points).
- The published trailing edge is sharp, so the section uses it as printed.
- The file is a 100 mm chord section, 20 mm deep: scale it uniformly to your chord, or import the STEP and sweep or loft it into a wing. Thickness scales with chord; the shape is the same at any size.
