Correlation of Cookoff Behavior of Rocket Propellants with Thermomechanical and Thermochemical Properties
Abstract
The fast and slow cookoff behaviour of a series of in-service and research composition rocket propellants have been evaluated using the standard SSCB (based on the NWC design) test, as part of a program in Explosives Ordnance Division (EOD) to develop an extensive insensitive munitions technology base. A modified SSCB test methodology, whereby the pressure output can be measured, was developed to enable a more quantitative measure of the reaction violence and to provide further insight into the cookoff mechanism. The temperature distribution/gradient at various positions and depths in the cylindrical propellant specimen, during fast and slow cookoff, were measured, in order to understand the marked difference in the severity of the response shown by some of the propellants when the heating rate was changed. Pressure and heating rate dependent thermochemical properties and thermomechanical properties of the propellants were measured and correlated with cookoff behaviour.
