Professor William S. Saric of Texas A&M University gave a seminar on Tuesday, March 11, on flight experiments on laminar flow control in swept-wing boundary layers. He explained how data are presented on boundary-layer transition to turbulence in low-disturbance flight environments with measurements including infra-red thermography and hotfilm anemometry. Saric's purpose was to study roughness-related issues of boundary-layer transition on a swept-wing model mounted on a wing of a Cessna O-2 aircraft. His measurements determined the transition locations for clean configurations and for enhanced surface roughness in order to stimulate an operational surface finish. The seminar was hosted by Dr. Foss.
