Abstract : A series of experiments was carried out with three propellants to determine whether or not certain features of the microstructure could be measured and correlated with response function behavior. Frequency, components in the microstructure were measured and correlated with particle-size distribution. Frequency components were also measured in dynamic burning experiments carried out at constant pressure, but these were essentially independent of size distributions, and therefore not fully correlatable with size distribution. Pressure-coupled response function measurements completed the series and indicated that the inherent microstructure is not the source of heterogeneous effects.
