Abstract
Abstract : The ignition characteristics of five operational propellants and seven model systems of varying composition were investigated by the use of high flux radiant energy as the ignition stimulus. The study provided considerable information which relates ignition characteristics to compositional factors. Findings of particular importance are: (1) for the types of propellants studied, ignitability is directly related to burning rate; within each system, those factors which increase burning rate also ease ignition; (2) minimum pressure for ignition of ammonium perchlorate propellants appears to be primarily related to the nature of the binder.
