Abstract:

Dynamic compaction is an important process in the deflagration to detonation transition behavior of porous beds of explosives and propellants. The characteristics of gas-driven dynamic compaction fronts have been studied in porous beds of two inert materials, Teflon 7C and melamine. These compaction fronts closely simulate those occurring during the early stages of DDT. In addition, isolation of compaction phenomena is achieved without any complications arising because of ignition and burning of energetic material. Measurements during the dynamic experiments provided wave and particle velocities, density profiles and pressure data.
