Femtosecond Laser Electronic Excitation Tagging Velocimetry in a Mach 6 Ludwieg Tube

Nonintrusive velocity measurements using femtosecond laser electronic excitation tagging (FLEET) were conducted at 1 kHz for both air and nitrogen flows in a Mach 6 Ludwieg tube under ∼600  Pa static pressure conditions. The signal from air and nitrogen were compared in freestream conditions and wit...
