Airfoil Data
DAYTONWRIGHTT1

The Dayton-Wright T-1 is a 13.7% chord-thickness airfoil with a maximum camber of 6.9% at 30% 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 -6.9°.

Thin airfoil theory predicts a stall angle near 11.0° and a peak lift-to-drag ratio around 71 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 14% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.

Designers evaluating the DAYTONWRIGHTT1 typically compare it against profiles of similar thickness: GOE 284 AIRFOIL, GOE 508 AIRFOIL, GOE 630 AIRFOIL, ARA-D 20% AIRFOIL, GOE 366 AIRFOIL. The NACA M2 AIRFOIL is another reference profile frequently considered alongside it.
