E582
EPPLER 582 AIRFOIL
Wing Geometry Simulator
The EPPLER 582 AIRFOIL is a 11.6% chord-thickness airfoil with a maximum camber of 5.8% at 42% 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 -5.8°.
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 E582 typically compare it against profiles of similar thickness: MH 83 13.29%, AH 83-150 Q, FX 63-158 AIRFOIL, EPPLER 580 AIRFOIL, STRAND AIRFOIL. The AH 79-100 B AIRFOIL is another reference profile frequently considered alongside it.
