N8H12
NACA 8-H-12 AIRFOIL
Wing Geometry Simulator
The NACA 8-H-12 AIRFOIL is a 9.5% chord-thickness airfoil with a maximum camber of 4.8% 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 -4.8°.
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 N8H12 appears in the wing design of at least 14 documented aircraft, including designs from Kasper and Tervamaki-Eerola. 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 N8H12 typically compare it against profiles of similar thickness: FAUVEL 14% AIRFOIL, lrn1007, GOE 450 AIRFOIL, GOE 182 (MVA H.27) AIRFOIL, TsAGI R-3a (12%). The NACA 64-108 AIRFOIL is another reference profile frequently considered alongside it.
