Airfoil Data
PSU94097

The PSU 94-097 (AIAA 2001-2478) is a 8.8% chord-thickness airfoil with a maximum camber of 4.4% at 42% 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 -4.4°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 60 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 PSU94097 typically compare it against profiles of similar thickness: RONCZ LOW DRAG FLYING WING AIRFOIL, RAF 32 MOD AIRFOIL, GOE 134 (MVA H.12) AIRFOIL, NACA 63(2)A-015, GOE 596 AIRFOIL. The S5010 is another reference profile frequently considered alongside it.
