Abstract:

The report describes an instrument constructed to measure the transmission of aircraft jet engine exhausts. This instrument was designed and built as an experimental breadboard system to explore the requirements and possibilities of a transmissometer in evaluating the measurement of optical transmission through an exhaust plume for characterizing the the exhaust parameters. It is designed as an advanced breadboard so that all optical functions remain flexible permitting modification as experience indicates change.
