Abstract
New sensor concepts base don rapidly tunable, room- temperature diode laser absorption are being developed for a variety of aeropropulsion testing and control applications. The sensors are compact, rugged, capable of remote operation, and sensitive to a number of important control parameters. This paper describes recent progress in the development of three specific sensor platforms: inlet air mass flux for in-flight aeroengine control; simultaneous density, temperature, and velocity measurements in high- speed propulsion test facilities; and multi-species emissions monitoring. The measurement principles and system architectures are reviewed, along with sample laboratory and field test data.
