Airfoil Data
ZV15_35

The Zv(15-35)16 is a 8.2% chord-thickness airfoil with a maximum camber of 4.1% at 15% 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 -4.1°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 58 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 ZV15_35 typically compare it against profiles of similar thickness: FX 68-H-120, E220 (11.48%), AG36, SA7026, NASA/LANGLEY RC-12(B)3 AIRFOIL. The BOEING 707 .08 SPAN AIRFOIL is another reference profile frequently considered alongside it.
