Reactions in PBX-9404 from low amplitude shock waves
Conference
·
OSTI ID:6882453
The reaction buildup in PBX-9404 from low amplitude (0.4 to 1.4 GPa) shock waves has been studied by impacting thick copper flyers into 146 mm dia specimens containing imbedded manganin pressure gauges. Significant pressure buildup and precursor waves were observed in all experiments. Detonation within 100 mm of run was observed for shock pressures above 1.3 GPa. Hydrodynamic calculations using an extended ignition and growth initiation model were compared to the experimental results. The inclusion of a minimum compression criteria improved the calculations but further refinement of the model will be required to describe low pressure initiation.
