Re α for Cp ° Turbulator at %c

Linear-vortex panel method with Thwaites/Head boundary layer, empirical low-Re laminar-bubble drag and a smoothed stall model (same engine as FF Wing Designer). It is an estimate for comparing sections — not XFoil and not wind-tunnel data. Below Re ≈ 50k real sections are very sensitive to bubbles and turbulators.

Chord mm Scale t/c to % Points/surface

Per airfoil (table above): original UIUC .dat, a re-paneled Selig .dat with the chosen point count, and the profile at the chosen chord as DXF (mm, layers PROFILE / CHORD) or SVG for templates and rib drawing. The ZIP contains all four for every selected airfoil.
