Investigation on the dissemination of solid BW agents and the effort devoted to the design and fabrication of a liquid BW agent disseminating store for use as a weapon on high speed, lowflying aircraft is studied. The theoretical studies of powder mechanics are outlined. The distribution of energy during the process of compaction of a finely divided solid is discussed. Experimental measurements of the shear strength of powders are reported. The loss of viability produced by exposing dry biological aerosols to heated airstreams is presented. The simulants Bg and Sm were exposed to temperatures in the range of 30 to 130 C. Experimental studies of deagglomeration by slipstream energy are reported. The current emphasis is on assessment of the loss in effectiveness due to agglomeration. Feeding systems for dry agents is reported. A full-scale laboratory model of the feeding system for an airborne disseminator is described, and future test plans are outlined.
