Abstract

Tunable diode laser absorption spectroscopy (TDLAS) with merits of fast, sensitive, and nonintrusive has been used to measure the flow field temperature, gas composition, mass flux, and other quantities in a wide range of practical applications. For its in situ measurements, TDL sensors has been deployed in turbofan (PW6000) inlet, scramjet engine inlet, scramjet isolator/combustor for maintenance of engine performance.
