Abstract

Templates have been taken from a fiberglass sailplane wing and a two-dimensional wind-tunnel model constructed to the coordinates of those templates. An investigation then was conducted in the Langley Low-turbulence pressure tunnel, the results being compared with data taken at the University of Stuttgart for the design section, the FX 66-l7AII-I82. The comparison indicated that the manufactured section had slightly higher drag and slightly lower maximum lift than the design section. An interactive graphics computer program was enployed to modify the manufactured section. The modified section was theoretically superior to the manufactured one although still inferior to the design.
