This report details the experimental portion of the Flameholder Combustion Instability investigation of the low frequency combustion instability rumble problem found in turbofan augmentors. The study examines 1 the spacial and temporal variations of pressure and heat-release in a flameholder rig designed to simulate augmentor operating conditions 2 some possible mechanisms for rumble under widely varying flow conditions and 3 the characteristic response of different flameholder configurations to longitudinal pressure disturbances.
