Airfoil Data
S3014

The S3014-095-85 is a thin 7.2% chord-thickness airfoil with a maximum camber of 3.6% at 34% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.6°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 56 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The slim profile minimises pressure drag at higher speeds but leaves limited spar depth for structural integration.

Designers evaluating the S3014 typically compare it against profiles of similar thickness: YS-930, USA 51 AIRFOIL, OAF128 AIRFOIL, CAST 10-2/DOA 2 AIRFOIL, SD2083 (9.0%). The NPL AIRFOIL FROM ARC CP 1372 is another reference profile frequently considered alongside it.
