SD5060
SD5060 (9.5%)
Wing Geometry Simulator
The SD5060 (9.5%) is a thin 6.8% chord-thickness airfoil with a maximum camber of 3.4% at 34% 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 -3.4°.
Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 54 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 SD5060 typically compare it against profiles of similar thickness: SD7090 (10%), RUTAN WING AIRFOIL, MH 60 10.08%, E71 (5.15%), S5020. The S4094 (root airfoil designed for and used on the E-flite UMX ASK-21 scale RC sailplane) is another reference profile frequently considered alongside it.
