Airfoil Data
GOE12K

The GOE 12K AIRFOIL is a 9.6% chord-thickness airfoil with a maximum camber of 4.8% 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 -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 GOE12K typically compare it against profiles of similar thickness: USA 28 AIRFOIL, GOE 796 AIRFOIL, NACA 64(2)-415 [NACA 6a series from Theory of Wing Sections], NACA 64(2)-415, EPPLER 328 AIRFOIL. The IST-MT1-18 is another reference profile frequently considered alongside it.
