Airfoil Data
GOE533

The GOE 533 AIRFOIL is a 11.5% chord-thickness airfoil with a maximum camber of 5.7% at 30% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.7°.

Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 67 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 11% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

The GOE533 appears in the wing design of at least 17 documented aircraft, including designs from Aero and New. Its proven track record across conventional and rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the GOE533 typically compare it against profiles of similar thickness: GOE 648 AIRFOIL, GOE 553 AIRFOIL, AH 81-K-144/17, EPPLER 553 AIRFOIL, EPPLER STE 87(-3)-914 AIRFOIL. The GOE 528 AIRFOIL is another reference profile frequently considered alongside it.
