Airfoil Data
SG6043

The SG6043 is a 10.3% chord-thickness airfoil with a maximum camber of 5.1% at 43% 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 -5.1°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 64 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 10% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the SG6043 typically compare it against profiles of similar thickness: AH 79-K-132/20, EPPLER 593 AIRFOIL, EPPLER 329 AIRFOIL, GOE 198 (L.F.G. 5294) AIRFOIL, GOE 460 AIRFOIL. The GOE 458 AIRFOIL is another reference profile frequently considered alongside it.
