Airfoil Data
DAVIS
Davis AIRFOIL
Wing Geometry Simulator
The Davis AIRFOIL is a 9.2% chord-thickness airfoil with a maximum camber of 4.6% at 40% 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 -4.6°.
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.
The DAVIS appears in the wing design of at least 21 documented aircraft, including designs from Consolidated and North American. Its proven track record across conventional and rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the DAVIS typically compare it against profiles of similar thickness: GOE 804 (EA 8) AIRFOIL, EPPLER 67 AIRFOIL, CLARK V AIRFOIL, FX 83-W-108, BOEING-VERTOL VR-7 AIRFOIL WITH TAB. The GOE 685 AIRFOIL is another reference profile frequently considered alongside it.
