Airfoil Data
N64015

The NACA 642-015 AIRFOIL is a thin 7.5% chord-thickness airfoil with a maximum camber of 3.7% at 35% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.7°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 56 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 N64015 appears in the wing design of at least 1 documented aircraft — notably by Industria. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the N64015 typically compare it against profiles of similar thickness: MRC15, GOE 143 (MVA H.20) AIRFOIL, cr001sm, NACA 642-015A AIRFOIL, MH 27 11.99%. The NACA 64A210 is another reference profile frequently considered alongside it.
