Airfoil Data
GOE326

The GOE 326 (PFALZ 55) AIRFOIL is a 8.8% chord-thickness airfoil with a maximum camber of 4.4% 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 -4.4°.

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.

The GOE326 appears in the wing design of at least 1 documented aircraft — notably by Slingsby. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the GOE326 typically compare it against profiles of similar thickness: GOE 325 (PFALZ 54) AIRFOIL, GOE 286 AIRFOIL, MH 116 9.84%, AH-7-47-6 AIRFOIL, GOE 195 AIRFOIL. The 74-130 WP2 is another reference profile frequently considered alongside it.
