Airfoil Data
IST-MT1-12

The IST-MT1-12 is a 11.1% chord-thickness airfoil with a maximum camber of 5.6% at 46% chord, suited to transonic and supercritical wing sections where aft-camber reduces wave drag. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -5.6°.

Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 67 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 IST-MT1-12 typically compare it against profiles of similar thickness: NACA M9 AIRFOIL, GOE 418 AIRFOIL, GOE 584 AIRFOIL, AH 93-W-145, NACA 64(3)-418. The GOE 624 AIRFOIL is another reference profile frequently considered alongside it.
