Effective Ignition Kinetics for LOVA Propellant

Abstract

Reactions leading to the ignition of nitramine propellants by hot metal fragments have been idealized as a sequence of two global reactions, the first endothermic and the second exothermic. The effective kinetics parameters were obtained by a nonlinear least squares fit of the theoretical expression for heat released (or absorbed) from an overall reaction to the endotherms and exotherms measured for the propellant in a DSC. Good representations of the data are found for a wild range in heating rates and inert gas purge flow rates. The simplified descriptions of the reactive heat release are proposed for use in a theoretical conductive ignition model being developed by K.K.Kuo.
