Airfoil Data
SC20710

The NASA SC(2)-0710 AIRFOIL is a thin 5.0% chord-thickness airfoil with a maximum camber of 2.5% at 41% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -2.5°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 49 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 SC20710 typically compare it against profiles of similar thickness: HQ 0/10 AIRFOIL, RAE 102 AIRFOIL, NACA 0010-64, NACA 0010-65, RAE 104 AIRFOIL. The GOE 598 AIRFOIL is another reference profile frequently considered alongside it.
