Airfoil Data
JN153

The JN-153 AIRFOIL is a thick 16.9% chord-thickness airfoil with a maximum camber of 8.5% at 34% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -8.5°.

Thin airfoil theory predicts a stall angle near 9.9° and a peak lift-to-drag ratio around 75 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 17% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the JN153 typically compare it against profiles of similar thickness: GOE 777 AIRFOIL, SIKORSKY DBLN-526 AIRFOIL, GOE 440 AIRFOIL, GOE 448 AIRFOIL, GOE 241 (MVA PR.1) AIRFOIL. The FX 60-177 AIRFOIL is another reference profile frequently considered alongside it.
