Airfoil Data
GOE14K

The GOE 14K AIRFOIL is a 8.7% chord-thickness airfoil with a maximum camber of 4.3% 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 -4.3°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 60 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 GOE14K typically compare it against profiles of similar thickness: GOE 456 AIRFOIL, GOE 499 AIRFOIL, GOE 458 AIRFOIL, GOE 155 (SSW D.1) AIRFOIL, HAM-STD HS1-708 AIRFOIL. The NN7 MK20 is another reference profile frequently considered alongside it.
