B. J. Wheatley
Univ. of Queensland, Australia

Keywords: laser absorption spectroscopy, hypersonic, scramjet

The paper describes the development of a tunable diode laser absorption spectroscopy (TDLAS) system that is used to characterise the species concentrations in hypersonic flows. The results of experiments on re-entrant and scramjet models are presented.
