Special Seminar: Luke Hill
November 13 @ 10:00 am - 11:00 am
Title:
Advanced Measurement Techniques and Hypersonic Wind Tunnel Testing
Abstract:
Hypersonic aerodynamics is an important, yet incredibly challenging area of research. Multiple technological hurdles must be overcome in order for capabilities, such as reusable, air-breathing hypersonic aircraft, to become feasible. This seminar will present recent contributions towards enhanced ground-testing approaches and analyses for hypersonic applications with a focus on boundary layer dynamics and optical measurement techniques. Measurements of hypersonic boundary layers using CO2-enhanced Rayleigh scattering, self-aligned focusing schlieren, and infrared thermography are presented. Qualitative and quantitative visualizations of flow features driving the laminar-to-turbulent transition process are discussed. All of the presented results were collected in the AFRL Mach-6 Ludwieg tube, but have broader utility and implications for the larger aerodynamic research community and adjacent areas of research (e.g., propulsion, microfluidics, explosives, oil/gas, etc.).
Bio:
Luke is a rising leader in high-speed wind tunnel testing, non-intrusive, optical measurement techniques, and aerospace . He received his Bachelor’s degree in Aerospace Engineering from NC State in 2017 where he also commissioned as a 2nd Lieutenant from the Air Force ROTC program. He served 3 years as an officer in the US Air Force where he received his Master’s degree in Aerospace Engineering from the Air Force Institute of Technology and performed research in the AFRL Mach-6 Ludwieg tube. Luke has continued to publish research in hypersonic aerodynamics with a focus on boundary layer transition and optical diagnostic development. He recently completed his PhD at AFIT and founded his own company, RH Technologies. He now focuses on developing optical measurement techniques for wind tunnels, providing test support and consultation services, and advancing American aerospace capabilities. One of his key desires is to spur a new generation of aerospace innovation in the Carolinas with a focus on hypersonics.
