Airfoil Data
NACAM6
NACA M6
Wing Geometry Simulator
The NACA M6 is a 8.2% chord-thickness airfoil with a maximum camber of 4.1% 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 -4.1°.
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.
The NACAM6 appears in the wing design of at least 86 documented aircraft, including designs from Porterfield and Amiot. 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 NACAM6 typically compare it against profiles of similar thickness: NACA M6 AIRFOIL, GRUMMAN K-3 AIRFOIL, E205 (10.48%), GOE 437 AIRFOIL, E174 (Dicke 8.92%). The NACA 64(2)-215 is another reference profile frequently considered alongside it.
