Airfoil Data
GOE479

The GOE 479 AIRFOIL is a 9.7% chord-thickness airfoil with a maximum camber of 4.8% 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 -4.8°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 63 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 GOE479 typically compare it against profiles of similar thickness: NACA 66(2)-415, GOE 140 (MVA H.17) AIRFOIL, EPPLER 555 AIRFOIL, GOE 174 (ALBATROS 5020) AIRFOIL, GOE 358 AIRFOIL. The GOE 328 AIRFOIL is another reference profile frequently considered alongside it.
