Seminars

For the development of high performance hypersonic platforms, ground testing is required since flight testing is exceptionally expensive and does not afford simultaneous off-body flow field measurements. High Mach numbers ground test facilities do not perfectly reproduce upper atmosphere flight environments, so measurements of flow properties both in the core flow and in the flow surrounding the test article are required. Run times for high enthalpy ground test facilities are often short (milliseconds), and flow properties may differ over millimeters and evolve in microseconds. In addition, many samples are needed to determine the statistical flow properties that are required for model development and validation. This seminar will present recently developed laser based stand-off methods for quantitative, temporally and spatially resolved measurements of complex flow properties in hypersonic ground test facilities.

Bio: Professor Miles received his B.S. in 1966, M.S. and 1967, and Ph.D. in 1972 all from Stanford University. He joined the faculty at Princeton University in the Fall of 1972. From 1980 to 1996 he served as Chairman of Engineering Physics. He became Emeritus at Princeton in 2013 and joined Texas A&M University in February 2017. He is a member of the National Academy of Engineering, a Fellow of the National Academy of Inventors, a Fellow of Optica (previously the Optical Society of America), a Fellow of the Hertz Foundation, and a Fellow of the American Institute for Aeronautics and Astronautics (AIAA). He is currently University Distinguished Professor and O’Donnell Foundation Chair V in Aerospace Engineering at Texas A&M and Robert Porter Patterson Professor Emeritus and Senior Scholar in Mechanical and Aerospace Engineering at Princeton. He is the Director of the Aerospace Laboratory for Lasers, ElectroMagnetics and Optics (ALLEMO) at Texas A&M University.
