FX 84-W-150
Wing Geometry Simulator
The FX 84-W-150 is a 11.7% chord-thickness airfoil with a maximum camber of 5.9% at 37% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.9°.
Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 68 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 12% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
Designers evaluating the FX84W150 typically compare it against profiles of similar thickness: EPPLER E1212 AIRFOIL, Curtis C-72, GOE 431 AIRFOIL, FX 78-PK-188/20, DU 80-176 V1. The FX 84-W-140 is another reference profile frequently considered alongside it.
