Abstract

This work represents the key results of a research project to predict the pressure wave propagation and flame spreading in a porous propellant charge ignited at one end by a high explosive initiator. The predictions attempted to model controlled laboratory tests with large grain M30 propellant confined in a cylinder and ignited by detonating an explosive disc at the open end. It was predicted that the magnitude of the initiator mass discharge rate determines the convective flame front speed and the pressure wave propagating into the propellant bed.
