Airfoil Data
GOE226

The GOE 226 (MVA H.36) AIRFOIL is a 14.0% chord-thickness airfoil with a maximum camber of 7.0% at 40% 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 -7.0°.

Thin airfoil theory predicts a stall angle near 10.9° and a peak lift-to-drag ratio around 71 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 14% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the GOE226 typically compare it against profiles of similar thickness: Dayton-Wright 6, GOE 527 AIRFOIL, GOE 711 AIRFOIL, RAF 89 AIRFOIL, CHEN AIRFOIL. The GOE 483 AIRFOIL is another reference profile frequently considered alongside it.
