Airfoil Data
GOE228

The GOE 228 (MVA H.38) AIRFOIL is a thick 15.3% chord-thickness airfoil with a maximum camber of 7.6% at 29% 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 -7.6°.

Thin airfoil theory predicts a stall angle near 10.4° and a peak lift-to-drag ratio around 73 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 15% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the GOE228 typically compare it against profiles of similar thickness: Griffith 30% Suction Airfoil, GOE 386 AIRFOIL, USA 35 A AIRFOIL, USA 35 AIRFOIL, GOE 441 AIRFOIL. The NASA/AMES 63A108 MOD C AIRFOIL is another reference profile frequently considered alongside it.
