Effect of temperature on the burning rate of solid propellants - A review

Abstract

T HE initial temperature of a solid propellant influences the burning rate and affects the performance of a rocket motor. A review of the literature reveals that a very thin zone beneath the burning surface is conceived to be effectively heated and important. However, this is not fully recognized in the quantitative prediction of the effect of temperature on the burning rate. Therefore, studies emphasizing the role of condensed and gas phase processes in different solid propellants are presented in this review so that there is some basis for unifying theories for predicting the effect of temperature on burning rate and other related properties like extinction, radiation effect, and deflagration pressure limit.
