Abstract : The deflagration to detonation transition (DDT) behavior of porous charges of a high-energy propellant (VLU) has been studied at both high and low confinements. The region of accelerating pressure buildup, necessary for DDT, occurred shortly before (both in time and distance) a transition to detonation. Propagation of compressive waves in both directions was associated with the buildup. The origin of the event producing these waves is unknown, but it appears to be a rapid heat release mechanism such as a thermal explosion. The DDT characteristics observed for this propellant are quite similar to those observed for tetryl in previous studies. The effect of confinement on the DDT susceptibility of this material at high porosities is small.
