Dissemination of Solid and Liquid BW Agents

Abstract

Theoretical and experimental results relative to the studies of the mechanics of dry powders are presented for: (1) the applied stresses and energies required for the compaction of powders, (2) shear strength of compacted powders, and (3) bulk tensile strength and bulk density of compacted powders as a function of compressive load and distance from the face of the piston. Data on aerosol decay as affected by relative humidity are reported for five powders. A statistical analysis of the behavior of aerosols is presented to explain the phenomena observed in the aerophilometer. Tests on dissemination and deagglomeration, using the wind tunnel, are described which establish an upper limit of approximately 0.58 g/cc density for compacted Sm which can be aerosolized efficiently by the aerodynamic breakup mechanism. Wind tunnel evaluation of a shroud for the discharge tube of the airborne dry agent disseminator is discussed.
