“…Because of strong temperature dependence, extrapolation of these valueto-ignition conditions is questionable. As a result of new experimental methods and theory development, several approaches for deriving thermokinetic parameters from ignition experiments [2,12,48,49] became available. This part of the report presents results obtained using laser techniques.…”

Laser and radiative ignition of 24 solid propellants and explosives was analyzed. The effect of ignition criterion used to calculate ignition delays from models was evaluated. Values for the optical parameters reflection, R A and absorption, k^ coefficients at wavelengths 0.36-1,1.06 and 10.6 urn were summarized. Effects of in-depth absorption and vaporization were considered. Methods for determining the relation of ignition delays for conductive heating (R x = 1, k A = infinity) and radiative heating at various wavelengths are presented. Methods for deriving kinetic parameters for the ignition and vaporization mechanisms for RDX-based materials were developed. Changes in the ignition mechanism at high radiative flux levels are discussed. A summary of the minimum flux levels needed for ignition and the Arrhenius kinetic parameters determined from ignition delay measurements with several energetic materials is presented.

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.
