GOE 457 AIRFOIL
Wing Geometry Simulator
The GOE 457 AIRFOIL is a thin 8.0% chord-thickness airfoil with a maximum camber of 4.0% at 30% 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 -4.0°.
Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 58 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 GOE457 typically compare it against profiles of similar thickness: GOE 676 (= M 12) AIRFOIL, NACA M14 AIRFOIL, GOE 278 (DAIMLER IX) AIRFOIL, NACA M12 AIRFOIL, OAF102 AIRFOIL. The EPPLER 325 AIRFOIL is another reference profile frequently considered alongside it.
