SIKORSKY SC1012R8 AIRFOIL
Wing Geometry Simulator
The SIKORSKY SC1012R8 AIRFOIL is a 8.7% chord-thickness airfoil with a maximum camber of 4.3% at 23% 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 -4.3°.
Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 60 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.
The SC1012R8 appears in the wing design of at least 2 documented aircraft — notably by Sikorsky. Its proven track record across rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the SC1012R8 typically compare it against profiles of similar thickness: K3311 (smoothed), GOE 310 (MVA H.42) AIRFOIL, GOE 177 AIRFOIL, GOE 155 (SSW D.1) AIRFOIL, GOE 456 AIRFOIL. The EPPLER 377 AIRFOIL is another reference profile frequently considered alongside it.
