Plane Shock Generator Explosive Lens: PH 13-8 Mo stainless steel versus 4340 steel shock wave separators and LX-13 versus PBX-9501 explosive particle velocity-time profiles
Sandia National Laboratories is currently involved in the optimization of a Plane Shock Generator Explosive Lens (PSGEL). This PSGEL component is designed to generate a planar shock wave transmitted to perform a function through a steel bulkhead without rupturing or destroying the integrity of the bulkhead. The PSGEL component consists of a detonator, explosive, brass cone and tamper housing. The purpose of the PSGEL component is to generate a plane shock wave input to 4340 steel bulkhead (wave separator) with a ferro-electric (PZT) ceramic disk attached to the steel on the surface opposite the PSGEL. The planar shock wave depolarizes the PZT 65/35 ferroelectric ceramic to produce an electrical output. Elastic, plastic I and plastic II waves with different velocities are generated in the steel bulkhead. The depolarization of the PZT ceramic is produced by the elastic wave of specific amplitude (10--20 Kilobars) and this process must be completed before (about 0. 15 microseconds) the first plastic wave arrives at the PZT ceramic. Measured particle velocity versus time profiles, using a Velocity Interferometer System for Any Reflector (VISAR) are presented for the brass and steel output free surfaces. Peak pressures are calculated from the particle velocities for the elastic, plastic I and plastic 11 waves in the steel. The work presented here investigates replacing the current 4340 steel with PH 13-8 Mo stainless steel in order to have a more corrosion resistant, weldable and more compatible material for the multi-year life of the component. Therefore, the particle velocity versus time profile data are presented comparing the 4340 steel and PH 13-8 Mo stainless steel. Additionally, in order to reduce the amount of explosive, data are presented to show that LX-13 can replace PBX-9501 explosive to produce more desirable results.
