Airfoil Data
AG46C03

The AG46c -03f is a thin 5.1% chord-thickness airfoil with a maximum camber of 2.6% at 30% 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.

Designers evaluating the AG46C03 typically compare it against profiles of similar thickness: JX-GS-10, AH21 9% version (Andrew Hollom), AG16, AG03 (flat aft bottom), Supermarine 371-II (tip). The AG55 is another reference profile frequently considered alongside it.
