Dissemination of Solid and Liquid BW Agents
GENERAL MILLS INC MINNEAPOLIS MN
The viability of Sm subjected to air streams simulating a jet engine exhaust was radically affected. Compaction tests on Sm showed some viability reduction. Measurements were made of the coefficient of friction and the bulk density of various powders. A theoretical analysis of the force required to lift a disk embedded in a dilatant material was conducted. Thermal conductivity and viscosity measurements of egg slurries were carried out. Rheological properties of Sm slurries were investigated. Boundary layer studies are reported which indicated that wind tunnel tests on deagglomeration are slightly conservative as compared to actual flight conditions. High-speed motion pictures give an insight into the breakup of Sm agglomerates. Deagglomeration to primary particles of Sm was observed. An investigation of the store-carrying capacities of an unmanned aircraft and a preliminary design of a liquid disseminating unit is included.
