NREL's S814 Airfoil (s814-nr)
Max thickness 24.1% at 28.4% chord. x/c y/c.
Two thick laminar-flow airfoils for the root portion of a horizontal-axis wind turbine blade, the S814 and 5815, have been designed and analyzed theoretically. For both airfoils, the primary objectives of high maximum lift, insensitive to roughness, and low profile drag have been achieved.
The 24-percent-thick S814 airfoil was desined with these characteristics to accommodate aerodynamic and structural considerations for the root region of a wind-turbine blade. In addition, the airfoil's maximum lift-to-drag ratio was designed to occur at a high lift coe猻꿓cient.
Design and Experimental Results for the S814 Airfoil
A 24% thick, airfoil, the S814, for the root region of a horizontal-axis wind turbine blade, has been designed and analyzed theoretically and verified experimentally in the low-turbulence wind tunnel of Delft University of Technology Low Speed Laboratory, The Netherlands.
S814 and S815 Airfoils: October 1991--July 1992
Two thick laminar-flow airfoils for the root portion of a horizontal-axis wind turbine blade, the S814 and S815, have been designed and analyzed theoretically. For both airfoils, the primary objectives of high maximum lift, insensitive to roughness, and low profile drag have been achieved.
Effects of Grit Roughness and Pitch Oscillations on the S814 Airfoil
An S814 airfoil model was tested in The Ohio State University Aeronautical and Astronautical Research Laboratory (OSU/AARL) 3x5subsonic wind tunnel (3x5) under steady flow with both stationary model conditions and pitch oscillations.
