Airfoil Data
N14

The N-14 is a thin 5.8% chord-thickness airfoil with a maximum camber of 2.9% at 30% 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 -2.9°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 52 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 N14 appears in the wing design of at least 8 documented aircraft — notably by Vickers. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the N14 typically compare it against profiles of similar thickness: RAE 5215 AIRFOIL, GIII BL86 AIRFOIL, GIII BL387 AIRFOIL, RAE 5214 AIRFOIL, AG53. The FX 84-W-175 is another reference profile frequently considered alongside it.
