title = "FLEET velocimetry at 100 kHz in a short-lived hypersonic facility",
abstract = "Femtosecond Laser Electronic Excitation Tagging (FLEET) is an unseeded molecular tagging velocimetry technique that has been demonstrated for hypersonic flow velocimetry in large-scale ground test facilities, typically operating at repetition rates of 1 kHz. Recent advancements in commercially available femtosecond laser systems have opened the door for time-resolved measurements in high-speed flows. This work presents FLEET velocimetry at 100 kHz in a short-lived hypersonic facility, enabling continuous measurement of high-speed flows with enhanced temporal resolution. A parametric study of the FLEET emission at different pressures in air and nitrogen was conducted. The system was deployed at Texas A\&M University{\textquoteright}s Hypervelocity Expansion Tunnel (HXT). Freestream velocity measurements and measurements behind an oblique shock near a hypersonic boundary layer were performed, demonstrating the feasibility of high-frequency FLEET in short-lived hypersonic ground test facilities.",
