A Fresh Look at the Classical Approach to Homogeneous Solid Propellant Combustion Modeling
Abstract
The term 'classical approach' is applied to those modeling efforts that use the experimental burning rate as the sole criterion for validation. The utility and limitations of this approach are discussed. It is argued that previous applications of the Classical Approach have too narrowly focused on a numerical match between model and actual burning rates. The result is an incomplete understanding of the full range of burning rate behavior implied by the basic idealization of the burning mechanism. Since a comparison of broad trends is of greatest heuristic interest, five different propellant data sets are developed which span a wide range of kinetics values. Accurate calculations of the burning rate pressure and temperature dependence are made and parallels drawn with actual propellant behavior. Likely weaknesses in the basic idealization are then identified.
