Burning rate data are presented with respect to initial temperature and pressure for three compounds that are currently used in propellant and explosive formulations. The dependence of burning rate on initial temperature and pressure is presented for ammonium perchlorate (AP), HMX, and RDX. Data for ingredients being considered for advanced propellants, such as CL-20, ammonium dinitramide (ADN), and hydrazinium nitroformate (HNF) are also presented and compared to the more traditional compounds. These ingredients are all capable of selfde agration,and their behavioroften controls the behavior of the propellantsin which they are the main ingredients.

This paper presents an overview of ammonium perchlorate (AP) based propellant ignitability. A CO 2 laser provided the radiant energy source. Neat AP ignition was performed on both production grade and high purity AP. The material was di©cult to ignite under the conditions. Five nonmetallized and sixteen metallized AP based formulations were used to examine the e¨ects of particle size, binder type, additives, and coarse-to-¦ne ratio (C/F) on propellant ignitability.
