Notes:


Coordinates generated by JavaFoil
Wind tunnel data from NACA TR-824 as digitized by Gregory P.D. Siemens in 1994 at the University of Saskatchewan.
The digitized TR-824 data has been processed and interpolated to generate all the plots and can not be guaranteed to be an exact match to the TR-824 plots.
