Airfoil Data
GOE462

The GOE 462 AIRFOIL is a thick 15.5% chord-thickness airfoil with a maximum camber of 7.8% at 30% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -7.8°.

Thin airfoil theory predicts a stall angle near 10.4° and a peak lift-to-drag ratio around 73 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 16% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

The GOE462 appears in the wing design of at least 1 documented aircraft — notably by Manuel. Its proven track record across rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the GOE462 typically compare it against profiles of similar thickness: WORTMANN FX 72-MS-150A AIRFOIL, GOE 434 AIRFOIL, EPPLER 421 AIRFOIL, USA 31 AIRFOIL, Glenn Martin 4. The EPPLER 485 AIRFOIL is another reference profile frequently considered alongside it.
