Airfoil Data
AH93W480B

The AH 93-W-480B is a thick 27.3% chord-thickness airfoil with a maximum camber of 13.6% at 42% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -13.6°.

Thin airfoil theory predicts a stall angle near 8.0° and a peak lift-to-drag ratio around 87 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 27% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the AH93W480B typically compare it against profiles of similar thickness: GOE 570 AIRFOIL, FX 79-W-470A, Marsden, GOE 561 AIRFOIL, GOE 571 AIRFOIL. The AH 93-W-215 is another reference profile frequently considered alongside it.
