Airfoil Data
TRAINER60

The TRAINER60 is a 9.3% chord-thickness airfoil with a maximum camber of 4.7% at 27% 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 -4.7°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 61 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 TRAINER60 typically compare it against profiles of similar thickness: EPPLER 340 AIRFOIL, EPPLER 625 AIRFOIL, GOE 610-B MOD. AIRFOIL, EPPLER 502 AIRFOIL, BOEING VERTOL V43012-1.58 AIRFOIL. The EPPLER 657 AIRFOIL is another reference profile frequently considered alongside it.
