This page is dedicated to the study of Deflagration to Detonation Transition (DDT) in granular HMX. The information presented here is the result of two summers of work at Los Alamos National Laboratory in the DX division. As part of the ongoing DX-2 As part of the explosives safety program at LANL our group has worked to develop models to describe the DDT of granular HMX explosives. A main goal of this effort is to develop truly predictive models. To accomplish this, a well-characterized set of data is needed that spans a significant parameter space. The aim of this work is to design and perform several experiments (approximately 30 tests) that significantly extends the experimental parameter space. The experiments are diagnosed as completely as possible given time and cost constraints. It is critical that these experiments be highly reproducible and that the materials used be well-characterized. Consequently, attention has also been paid to both these issues in this work. Here we present the initial experimental results that establish the repeatability of the experiments and report the effect of varying the density.
