Flameholder Combustion Instability Study. Volume II. Experimental Program.

Abstract

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.
