Airfoil Data
SG6050

The SG6050 is a 10.9% chord-thickness airfoil with a maximum camber of 5.5% at 38% 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 -5.5°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 66 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 11% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the SG6050 typically compare it against profiles of similar thickness: GW 30, GOE 801 (MVA 301) AIRFOIL, GOE 802 A AIRFOIL, GOE 802 B AIRFOIL, GOE 802 AIRFOIL. The 0.018772 0.005079 is another reference profile frequently considered alongside it.
