Airfoil Data
GOE572

The GOE 572 AIRFOIL is a thick 17.6% chord-thickness airfoil with a maximum camber of 8.8% at 30% 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 -8.8°.

Thin airfoil theory predicts a stall angle near 9.6° and a peak lift-to-drag ratio around 76 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 18% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the GOE572 typically compare it against profiles of similar thickness: GOE 244 (MVA PR.4) AIRFOIL, FX 77-W-270, FX 77-W-270S, HAM-STD HS1-430 AIRFOIL, EPPLER 863 STRUT AIRFOIL. The EPPLER 548 AIRFOIL is another reference profile frequently considered alongside it.
