## Overall (mm)

| length | width | height |
|---|---|---|
| 100.0 | 20.0 | 13.71 |

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- 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.

## Questions

**How thick is the Wortmann FX 63-137?**

Maximum thickness 13.71 % of chord at 30.9 % chord: 13.71 mm on a 100 mm chord (computed from the UIUC coordinates).

**How much camber does the Wortmann FX 63-137 have?**

Maximum camber 5.97 % of chord at 53.3 % chord (computed from the UIUC coordinates).

**How do I use it for my wing?**

Scale the 100 mm section to your chord (e.g. 180 mm chord = 180 % scale), then extrude or loft between root and tip sections. For a tapered wing, scale a root and a tip copy and loft between them.
