Development of a recent experimental program to investigate the effects of streamwise curvature on boundary-layer transition required making a bendable, heated, and instrumented test wall, a rather nonconventional surface. The present paper describes this surface, the design choices made in its development, and how uncertainty analysis was used, beginning early in the test program, to make such design choices. Published uncertainty analysis techniques were found to be of great value. Finally, it is shown how the uncertainty analysis was used to determine whether the test surface was qualified for service.
