By means of theoretical modeling as well as by the experimental investigation of various propellants, further elements are presented to consolidate the understanding of the combustion of ammonium perchlorate propellants. Available descriptions of A.P. combustion, binder pyrolysis and composite propellant combustion are presented and compared favorably to experimental results on combustion wave details or burning rate sensitivity to initial temperature. A number of propellants, based on ammonium perchlorate, carboxy terminated polybutadiene, polystyrene, polyurethane, with various additives, are investigated. In some instances burning rate laws which differ from the law with a moderate pressure exponent, characteristic of a diffusion mechanism, are found, with plateau effects or high pressure sensitivity.
