A compelling need for knowledge of the properties (temperature, density, velocity, composition, etc.) of the flows produced by propulsion systems has recently surfaced in many areas. Of specific interest to the Air Force Rocket Propulsion Laboratory (AFRPL) is knowledge of properties within combustion chambers, particularly for solid fueled motors employing metallized propellants, and properties affecting exhaust plume observables (e.g., smoke, infrared radiation signatures, ultra-violet radiation signatures, radar cross sections, etc.). Methods of making measurements within combustion flows must avoid influencing the very phenomena to be measured and, generally, must be made from without (nonintrusive) because of the harsh environment. This report is aimed at defining the needs for 'combustion diagnostics' associated with rocket propulsion, assessing the status and utility of the applicable techniques, and establishing a basis for the research and development required to provide techniques to meet the defined needs.
