A number of binary mixtures, components of which are propellant ingredients, were examined in steel walled tubes for their DDT behavior at 60-70% theoretical maximum density (TMD). Several commercial propellants and one 4-component, composite model were also examined. A number of compositional effec

โฆ Synopsis
Simplified propellant models, consisting of a mixture of ammonium perchlorate, aluminum and wax with and without 20% of the explosive HMX, were surveyed for detonability, shock sensitivity and detonation velocity as a function of charge diameter and compaction. Both models exhibited the behavior characteristic of Group 2 explosives, i.e., a critical diameter for detonation increasing with decreasing porosity.

Most theoretical treatments of solid propellant combustion assume a highly idealized mechanism: an exothermic surface decomposition reaction tbllowed by a single exothermic gas phase reaction. Despite its conceptual simplicity this mechanism does not permit an exact solution to the conservation equa
