Design of Aerothermoelastic Experiments in the AFRL Mach 6 High Reynolds Number Facility. Riley, Z. B., Perez, R., & Brouwer, K. R. In AIAA SCITECH 2023 Forum, 2023. AIAA Paper 2023-0948. _eprint: https://arc.aiaa.org/doi/pdf/10.2514/6.2023-0948doi abstract bibtex View Video Presentation: https://doi.org/10.2514/6.2023-0948.vidAn experiment was recently conducted in the Air Force Research Laboratory Mach 6 High Reynolds Number Facility exploring the aerothermoelastic response of metallic panels with thicknesses of 381, 508, and 635 μm. Simultaneous, full-field measurements of the panel response were made using stereo digital image correlation, an infrared camera, and a shadowgraph system. Each panel was also instrumented with strain gages and thermocouples. Aeroelastic simulations were carried out to identify the freestream conditions and loading required to exhibit large-amplitude, oscillatory response. Key features of the model design including; an increased length, a pressurized and controllable cavity, and angle of attack variation made it possible to observe panel flutter. Sustained and repeatable large-amplitude oscillations were observed for each panel thickness at different freestream conditions.
