Airfoil Data
GOE329

The GOE 329 (PFALZ 58) AIRFOIL is a 10.6% chord-thickness airfoil with a maximum camber of 5.3% 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 -5.3°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 65 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.

Designers evaluating the GOE329 typically compare it against profiles of similar thickness: EPPLER EC 86(-3)-914 AIRFOIL, GOE 493 AIRFOIL, E210 (13.64%), GOE 63 AIRFOIL, CURTISS CR-1 AIRFOIL. The MI-VAWT1 is another reference profile frequently considered alongside it.
