Airfoil Library

Sections in the library

1,668

UIUC, refitted to CST. Coordinates, DXF and a stored polar sweep on every one of them, free.

Any Reynolds number

The stored sweep is fixed. NeuralFoil re-runs any section at the conditions you actually fly.

Loft one into a 3D wing, get lift and drag for the whole planform, export STEP or STL.

Connect the library to Claude, ChatGPT or Grok and ask for all of it in plain language.

Using foil.tools, find me a section for a 2 m glider wing at Re 300k that stalls gently.

Four- and five-digit profiles from the National Advisory Committee for Aeronautics, used across general aviation.

Airfoils designed by Richard Eppler, widely used in gliders and low-speed aircraft.

Historic profiles from the Aerodynamische Versuchsanstalt (AVA) Göttingen, foundational to early aerodynamics.

Profiles by Michael Selig (UIUC), optimised for low Reynolds number and R/C applications.

Profiles by Martin Hepperle, primarily for model aircraft and UAVs at low Reynolds numbers.

Profiles by Horstmann and Quast designed for high-performance sailplanes.

Royal Aircraft Factory profiles originating from early British aviation research.

Royal Aircraft Establishment profiles, developed for jet-age applications.

Profiles from the Ritz–Göttingen series for model sailplanes.

Profiles from the Flygtekniska Försöksanstalten (Swedish Aeronautical Research Institute).

Wind-turbine optimised profiles from Delft University of Technology.

Franz Xaver Wortmann profiles, used in high-performance gliders.

OSO series profiles.

Profiles from various designers and databases not covered by the named series above.

Profiles with no identified series or origin.

All profiles sourced from the UIUC Airfoil Database and fitted using CST (Kulfan) parameterization.
