Airfoil Data
FX79W151A

The FX 79-W-151 A is a 11.3% chord-thickness airfoil with a maximum camber of 5.7% at 34% 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 -5.7°.

Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 67 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 11% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the FX79W151A typically compare it against profiles of similar thickness: EPPLER 855 AIRFOIL, MH 102 16.99%, MH 84 13.69%, AH 80-140, NN7 MK20. The FX 79-L-100 is another reference profile frequently considered alongside it.
