Initiation and gas expansion model for the light-initiated explosive silver acetylide-silver nitrate
Light-initiated high explosive, silver acetylide-silver nitrate (SASN), has been used to produce simulated X-ray blowoff impulse loading on reentry vehicles to study the system structural response. A model of the explosion process is required for estimating the average pressure profile delivered to the surface during the loading. A simplified model of the initiation and gas expansion process of the explosion is described. Observations from several experiments in which thin metallic flyer plates were accelerated with SASN were used to develop the model. Predictions of the approximate average pressure-time loading on the surface of a test structure is now possible. The pressure-time model can also be used to predict the motion of explosively driven thin solid flyer plates.
