Abstract
Distributed particle combustion in solid propellant rocket motors may be a significant cause of acoustic combustion instability. A Rijke burner has been developed as a tool to investigate the phenomenon. Previous improvements and characterization of the upright burner lead to the addition of a particle injection flame. The injector flame increases the burner's acoustic driving by about 10% which is proportional to the injector's additional 2 g/min of gas. Frequency remained fairly constant for all test cases. Preliminary testing shows that the combustion of 17.8 µm or 33.4 µm aluminum powder can triple the acoustic driving in the burner from the "gas only" rate ...
