Airfoil Data
GOE328

The GOE 328 AIRFOIL is a 8.5% chord-thickness airfoil with a maximum camber of 4.2% at 30% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -4.2°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 59 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 GOE328 typically compare it against profiles of similar thickness: GOE 379 AIRFOIL, N-9, NASA/LANGLEY LS(1)-0413 (GA(W)-2) AIRFOIL, MARSKE PIONEER IA AIRFOIL (NACA 23112/43012A HYBRID), A18 (original). The S1210 12% is another reference profile frequently considered alongside it.
