JX-GS-04
JX-GS-04
Wing Geometry Simulator
The JX-GS-04 is a thin 4.9% chord-thickness airfoil with a maximum camber of 2.4% at 25% 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 -2.4°.
Thin airfoil theory predicts a stall angle near 12.0° and a peak lift-to-drag ratio around 49 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-04 typically compare it against profiles of similar thickness: RG 14A-1.4/7.0 AIRFOIL, NPL 9510 AIRFOIL, RAF 27 AIRFOIL, EPPLER 874 HYDROFOIL AIRFOIL, HAM-STD HS1-404 AIRFOIL. The GIII BL75 AIRFOIL is another reference profile frequently considered alongside it.
