Airfoil Data
DU84132V

The DELFT DU84-132V3 AIRFOIL (MEASURED) is a 9.7% chord-thickness airfoil with a maximum camber of 4.9% at 38% 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 -4.9°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 63 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.

Designers evaluating the DU84132V typically compare it against profiles of similar thickness: GOE 477 AIRFOIL, GOE 623 AIRFOIL, E216 (10.4%), EPPLER 337 AIRFOIL, Rhode St. Genese 30. The FX 66-S-171 AIRFOIL is another reference profile frequently considered alongside it.
