Supermarine 371-II (tip)
Wing Geometry Simulator
The Supermarine 371-II (tip) is a thin 5.1% chord-thickness airfoil with a maximum camber of 2.6% at 50% 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 -2.6°.
Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 50 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 SUPERMARINE371II appears in the wing design of at least 5 documented aircraft — notably by Supermarine. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the SUPERMARINE371II typically compare it against profiles of similar thickness: AG03 (flat aft bottom), AH21 9% version (Andrew Hollom), GOE 55 AIRFOIL, JX-GS-10, NASA/LANGLEY RC-08(B)3 AIRFOIL. The NACA 65-210 is another reference profile frequently considered alongside it.
