Airfoil Data
AH94145

The AH 94-145 is a 12.7% chord-thickness airfoil with a maximum camber of 6.4% at 41% 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 -6.4°.

Thin airfoil theory predicts a stall angle near 11.3° and a peak lift-to-drag ratio around 70 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 13% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the AH94145 typically compare it against profiles of similar thickness: GOE 433 AIRFOIL, MH 114 13.02%, EPPLER 604 AIRFOIL, EPPLER 583 AIRFOIL, NACA 4418. The GOE 383 AIRFOIL is another reference profile frequently considered alongside it.
