Airfoil Data
S8037

The S8037 (16%) is a 10.6% chord-thickness airfoil with a maximum camber of 5.3% at 33% 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 -5.3°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 65 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 S8037 typically compare it against profiles of similar thickness: GOE 63 AIRFOIL, CURTISS CR-1 AIRFOIL, E210 (13.64%), GOE 303 (FRIEDRICHSHAFEN G03) AIRFOIL, GOE 493 AIRFOIL. The RAF 26 AIRFOIL is another reference profile frequently considered alongside it.
