Airfoil Data
FX05H126

The WORTMANN FX 05-H-126 AIRFOIL is a 10.7% chord-thickness airfoil with a maximum camber of 5.4% at 37% 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 -5.4°.

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.

The FX05H126 appears in the wing design of at least 2 documented aircraft, including designs from Beatty and Farrar. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the FX05H126 typically compare it against profiles of similar thickness: GOE 360 AIRFOIL, MRC-20, GOE 509 AIRFOIL, HAM-STD HS1-712 AIRFOIL, GOE 323 (HANSA-BRANDENBURG V.1) AIRFOIL. The GOE 744 AIRFOIL is another reference profile frequently considered alongside it.
