Notes

  • SD7062: Michael Selig and John Donovan (SD series). Maximum thickness 13.98 % of chord at 27.2 % chord; maximum camber 3.97 % of chord at 38.8 % chord.
  • Coordinates from the UIUC Airfoil Coordinates Database (M. Selig, UIUC Applied Aerodynamics Group), file sd7062.dat, titled 'SD7062 (14%)'. 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 SD7062?

Maximum thickness 13.98 % of chord at 27.2 % chord: 13.98 mm on a 100 mm chord (computed from the UIUC coordinates).

How much camber does the SD7062 have?

Maximum camber 3.97 % of chord at 38.8 % 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.
