NACA 0008 airfoil
What is the exact shape of the NACA 0008 airfoil, and what do the digits mean? · Standard part · basis: Computed from the NACA equations (Report 460 / Report 610, restated in NASA TM-4741)

Notes
- NACA 0008: symmetric, 8 % thick.
- NACA 4-digit: first digit = maximum camber in % of chord, second = its position in tenths of chord, last two = maximum thickness in % of chord (NACA Report 460).
- Ordinates are in % of chord from the leading edge, computed from the published equations with the closed-trailing-edge thickness coefficient (−0.1036, as in NASA TM-4741). The original reports use an open trailing edge (−0.1015); the difference is under 0.03 % of chord near the trailing edge.
- 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 NACA 0008?
Maximum thickness 8.00 % of chord at 29.9 % chord: 8.00 mm on a 100 mm chord.
Where is the NACA 0008's camber?
None: it is symmetric (upper and lower surfaces mirror).
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.
