Airfoil Data
SC1095R8

The SIKORSKY SC1095R8 AIRFOIL is a thin 5.5% chord-thickness airfoil with a maximum camber of 2.7% at 27% 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 -2.7°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 51 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 SC1095R8 appears in the wing design of at least 8 documented aircraft, including designs from Sikorsky and Mitusbishi. Its proven track record across conventional and rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.

Designers evaluating the SC1095R8 typically compare it against profiles of similar thickness: HQ 1.0/9 AIRFOIL, AG27 Bubble Dancer DLG by Mark Drela | The AG2x airfoils are intended to be used on composite versions of the Bubble Dancer and the Allegro-Lite., GIII BL288 AIRFOIL, EH 2.0/7.0, NACA/LANGLEY SYMMETRICAL, SUPERCRITICAL AIRFOIL. The GOE 190 (MVA MK.18) AIRFOIL is another reference profile frequently considered alongside it.
