NACA2415
NACA 2415
Wing Geometry Simulator
The NACA 2415 is a 9.4% chord-thickness airfoil with a maximum camber of 4.7% at 30% 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 -4.7°.
Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 62 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 NACA2415 appears in the wing design of at least 54 documented aircraft, including designs from Fiat and Northrop. Its proven track record across conventional and rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the NACA2415 typically compare it against profiles of similar thickness: GOE 629 AIRFOIL, FX 63-110 AIRFOIL, EPPLER 377 (MODIFIED) AIRFOIL, EPPLER 377 AIRFOIL, HQ 3.0/13 AIRFOIL. The NACA 2415 is another reference profile frequently considered alongside it.
