WORTMANN FX 62-K-131 AIRFOIL
Wing Geometry Simulator
The WORTMANN FX 62-K-131 AIRFOIL is a 10.4% chord-thickness airfoil with a maximum camber of 5.2% at 43% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.2°.
Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 64 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 10% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
The FX62K131 appears in the wing design of at least 1 documented aircraft — notably by Akaflieg. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the FX62K131 typically compare it against profiles of similar thickness: HQ 3.0/15 AIRFOIL, NACA6409 9%, HQ 3.5/14 AIRFOIL, WACO COOTIE AIRFOIL, EPPLER 338 AIRFOIL. The NACA M3 is another reference profile frequently considered alongside it.
