SD7037 airfoil — dimension sheet

Basis: Coordinates from the UIUC Airfoil Coordinates Database; thickness, camber and section by Xem Studio
Catalog version: 2026-10-20

Overall (mm): length 100.0, width 20.0, height 9.2
- SD7037: Michael Selig and John Donovan (SD series). Maximum thickness 9.20 % of chord at 29.0 % chord; maximum camber 3.02 % of chord at 39.9 % chord.
- Coordinates from the UIUC Airfoil Coordinates Database (M. Selig, UIUC Applied Aerodynamics Group), file sd7037.dat, titled 'SD7037-092-88'. 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.
