Airfoil Data
JX-GS-15

The JX-GS-15 is a thin 5.2% chord-thickness airfoil with a maximum camber of 2.6% at 31% 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 JX-GS-15 typically compare it against profiles of similar thickness: BOEING-VERTOL VR-15 AIRFOIL, AG55, AG11, RAF 26 AIRFOIL, USA 46 AIRFOIL. The USA 5 AIRFOIL is another reference profile frequently considered alongside it.
