Abstract:

Experimental data concerning nonacoustic combustion instability of solid propellants are presented and compared with the predictions of theoretical models. This comparison reveals that the models are inadequate to predict the behavior of certain propellants, such as in the case of polyurethane binder systems, where at least two basic assumptions used in formulating the models are seriously violated. Contrary to these assumptions, the heterogeneity of the propellant and the relationship of the thermal wave thickness to the oxidizer particle sizes are factors that cannot be neglected. Author
