Airfoil Data
MH122

The MH 122 9.32% is a thin 7.6% chord-thickness airfoil with a maximum camber of 3.8% at 48% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.8°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 57 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The slim profile minimises pressure drag at higher speeds but leaves limited spar depth for structural integration.

Designers evaluating the MH122 typically compare it against profiles of similar thickness: S3021-095-84, GOE 210 (DAIMLER) AIRFOIL, WORTMANN FX L V-152 AIRFOIL, EPPLER 360 AIRFOIL, BOEING 737 MIDSPAN AIRFOIL. The EPPLER 479 AIRFOIL is another reference profile frequently considered alongside it.
