Airfoil Data
GOE10K

The GOE 10K AIRFOIL is a thin 3.3% chord-thickness airfoil with a maximum camber of 1.7% at 50% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -1.7°.

Thin airfoil theory predicts a stall angle near 12.0° and a peak lift-to-drag ratio around 45 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 GOE10K typically compare it against profiles of similar thickness: BOEING-VERTOL VR-9 AIRFOIL, GOE 5K AIRFOIL, HT 13, 30P-30N Main Element (MDA), GOE 445 AIRFOIL. The N-11 is another reference profile frequently considered alongside it.
