Abstract:

The report describes the results of a test in which four air entrainment subsystem AES conceptual models were exposed to a simulated nuclear airblast at 3000-psi overpressure. The BOSS explosively driven blast simulator was used to generate a blast wave pressure-time profile closely matching one-ninth scale of a 1-Mt nuclear burst in a 7-in. by 28-in. rectangular blast duct 100-ft long. AES models were welded to the blast duct and instrumented with piezoelectric pressure gauges. Results include pressure-time histories at blast valve locations and accumulator stations, and observations of model component failure modes. This test represents the first time that sub-scale air entrainment subsystems have ever been exposed to blast waves in air at high overpressure levels, and the results indicate substantial differences between predicted and measured pressures.
