Airfoil Data
GOE173

The GOE 173 (ALBATROS 6020) AIRFOIL is a 9.6% 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 62 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 GOE173 typically compare it against profiles of similar thickness: NACA 65(2)-415, GOE 392 AIRFOIL, GOE 693 AIRFOIL, EPPLER 68 AIRFOIL, S4022. The EPPLER 1213 AIRFOIL is another reference profile frequently considered alongside it.
