Dr. McLaughlin is Professor of Aerospace Engineering at the Pennsylvania State University, a position he has held since 1986. He received his graduate degrees including the Ph.D. in Aeronautics and Astronautics, from the Massachusetts Institute of Technology in 1970, following a BS degree from the University of Manitoba in Canada. Following his studies at MIT, he was a Professor at Oklahoma State University for 11 years and he spent 5 years as Group Manager at Dynamics Technology Inc., in Torrance, CA. He teaches and conducts research in the general areas of experimental aerodynamics and aeroacoustics focusing on measurements that connect flow instabilities and turbulence to the radiated noise. High-speed jet noise experiments in the high subsonic and supersonic flow regimes have provided major data bases for the validation of developing jet noise simulation codes. More recent contributions have explored the accuracy of simulating high-speed heated jets with mixtures of helium/air producing gas mixtures of comparable density and speed of sound. Other research has included experimental studies of centrifugal turbo-machinery, studies of the supersonic shear layer relevant to fuel-air mixing in scramjet propulsion systems and an R&D project involving wing-in-ground-effect vehicles. The R&D project has involved extensive wind tunnel experiments leading to model scale field tests. Professor McLaughlin has served on several advisory panels including the FAA REDAC Committee. He is a past chair of the Aerospace Department Chairs Association and the AIAA Aeroacoustics Technical Committee.
