Airfoil Data
GOE373

The GOE 373 AIRFOIL is a 8.3% chord-thickness airfoil with a maximum camber of 4.1% 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 -4.1°.

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 GOE373 typically compare it against profiles of similar thickness: GOE 602 AIRFOIL, GOE 602 MOD. AIRFOIL, ONERA OA212 AIRFOIL, NACA 64(1)-212 MOD A, EPPLER 479 AIRFOIL. The LIEBECK L1003 AIRFOIL is another reference profile frequently considered alongside it.
