Airfoil Data
GOE07K

The GOE 7K AIRFOIL is a 10.0% chord-thickness airfoil with a maximum camber of 5.0% at 50% chord, suited to transonic and supercritical wing sections where aft-camber reduces wave drag. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.0°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 64 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 10% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the GOE07K typically compare it against profiles of similar thickness: LA2573A, GOE 574 AIRFOIL, EPPLER 598 AIRFOIL, MARSKE XM-1D AIRFOIL (F14-3.0), NACA 63(3)-218. The S4158 is another reference profile frequently considered alongside it.
