FX 75-VG-166/22
Wing Geometry Simulator
The FX 75-VG-166/22 is a 10.8% chord-thickness airfoil with a maximum camber of 5.4% at 43% 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 -5.4°.
Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 66 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 11% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
Designers evaluating the FX75VG166 typically compare it against profiles of similar thickness: GOE 478 AIRFOIL, BOEING VERTOL V43015-2.48 AIRFOIL, AH 82-150 A, MH 115 11.06%, GOE 190 (MVA MK.18) AIRFOIL. The GOE 234 (MVA CA5) AIRFOIL is another reference profile frequently considered alongside it.
