Workshop Report: Measurement Techniques in Highly Transient, Spectrally Rich Combustion Environments.

Abstract

With the emergence of advanced propulsion systems such as liquid propellant (LP), electrothermal-chemical (ETC), electromagnetic (EM), conventional hypervelocity, and in-bore ramjet, the measurement of combustion phenomena has become more complex. The data associated with these systems can be rich in high-frequency components, and share similar transient behavior. Measurement techniques associated with conventional solid propellant systems are not always capable of accurately recording these phenomena. The accuracy of pressure and acceleration measurements in combustion chambers, barrels, and on-board projectiles has been compromised by the lack of a fundamental understanding of the effects of the mounting configuration and the mechanical and electrical components of the transducer on the integrity of the measurement. Consequently, the system development and technical understanding of the physical processes involved in the ignition and combustion of such advanced propulsion systems have been compromised. A workshop was needed to bring together experts from the aforementioned and related communities to disseminate knowledge of lessons learned and to discuss the techniques necessary to make high-fidelity pressure measurements in these environments. This report will state the objectives, identify the participants who met to address them, provide a list of the technical presentations made, present highlights from these presentations and the discussions that they prompted, and end with conclusions and recommendations which came out of the workshop.
