Goodyear Aerospace Corporation has conducted an exploratory study to determine feasibility of inflated bomblets. The effort varied from fundamental studies to development of sophisticated test equipment for determining particle size and distribution of a simulant agent in inflated rubber bladders. A parametric structural analysis based on gas weights, the ideal gas law along with stress-strain relationships for perfectly elastic materials at various durometers, and a flight simulation computer program were initiated for determining trajectory histories and loads for three bomblet weights. Theoretical studies of particle dynamics during and after inflation along with bladder inflation gas temperatures were also completed. Tests of particle settling rates showed that the distribution of particles are governed primarily by the fluid dynamics of the air in the bladder and only to a small extent by gravity forces. Burst tests, conducted after inflation to investigate the effects of biaxial extension stress in the bladder walls on the settled talc particles along with differential pressure effects on the payload, resulted in the violent burst of all bladders with effective payload and gas mix. Limited functional mechanical component bench testing on the experimental bomblet demonstrated feasibility of the concept, but the weighted probe triggering mechanism proved unreliable.
