Airfoil Data
SD6080

The SD6080 (9.2%) is a 8.2% chord-thickness airfoil with a maximum camber of 4.1% at 35% 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.

Designers evaluating the SD6080 typically compare it against profiles of similar thickness: GOE 269 AIRFOIL, GRUMMAN K-3 AIRFOIL, E387, NACA M6 AIRFOIL, NACA M6. The GOE 242 (MVA PR.2) AIRFOIL is another reference profile frequently considered alongside it.
