Airfoil Data
GOE368

The GOE 368 AIRFOIL is a thin 7.2% chord-thickness airfoil with a maximum camber of 3.6% at 30% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.6°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 55 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 GOE368 typically compare it against profiles of similar thickness: A18 (smoothed), NACA 65-410, Eiffel 10 (Wright) - 1903 Wright Flyer airfoil, NACA M16 AIRFOIL, BE50 (smoothed). The HAM-STD HS1-404 AIRFOIL is another reference profile frequently considered alongside it.
