Deflagration-to-detonation transition in Bullseye powder
- 26 Downloads
A series of compaction experiments was conducted to evaluate the mechanical, reactive, and deflagration-to-detonation transition behavior in Alliant Bullseye powder. Using a novel application of photonic Doppler velocimetry and light fibers, the experiments measured both compaction and combustion waves in porous beds of Bullseye subjected to impact by gun-driven pistons. Relationships between initial piston velocity and transition distance are shown. Comparison is made between the Bullseye response and that found in classic Type I DDT.
