An Investigation of the Steady-State Burning of Ammonium Perchlorate Composite Solid Propellants

Abstract

A new, comprehensive steady-state model describing the burning of non-metalized, unimodal ammonium perchlorate (AP)-polymeric composite solid propellant has been developed and shown to yield better results than previous models. This new model incorporates a near-surface AP decomposition flame perturbed by fuel vapor diffusion (after Chaiken) followed by a granular diffusion flame (after Summerfield), and is termed the 'modified granular diffusion flame' (MGDF) model. The MGDF model permits numerical prediction of the influence of pressure, AP particle size, mixture ratio and propellant initial temperature on propellant burning rate. While the new model has proven notably successful, evaluation of the capabilities of it and other models is constrained by the limited existing data base.
