Airfoil Data
DU-80-176-V1

The DU 80-176 V1 is a 11.8% chord-thickness airfoil with a maximum camber of 5.9% at 39% 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 -5.9°.

Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 68 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 12% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the DU-80-176-V1 typically compare it against profiles of similar thickness: EPPLER 344 AIRFOIL, GOE 414 AIRFOIL, EPPLER 431 AIRFOIL, FX 78-PK-188/20, EPPLER E1212 AIRFOIL. The E216 (10.4%) is another reference profile frequently considered alongside it.
