| Abstract Scope |
Five one dimensional shock initiation experiments have been carried out on the HMX-based polymer bonded explosive PBX-9012. This explosive comprises of 90% HMX and 10 % Viton A. The experiments delivered sustained pulses of shock pressures ranging from 2.0 to 4.4 GPa. This resulted in a turn over to detonation ranging from 4.9 to 20 mm from the impact plane. Reactive growth wave-profiles have been measured in up to eleven Legrangian locations using the electromagnetic embedded gauge technique at the Los Alamos National Laboratory gas gun facility. In addition, the evolution of the shock to detonation transition has been tracked using the embedded shock tracker gauge comprising of up to 118 measurement locations. These data have been used to determine the relative shock sensitivity and the unreacted Equation of State for PBX-9012. |
