Laboratory-Scale High-Explosive Cratering and Ejecta Phenomenology Studies.
Abstract
A Cratering Facility was designed and constructed for the purpose of performing laboratory-scale, high-explosive cratering experiments. Fifty-five events were conducted in which centrally initiated, spherical, lead-azide charges were detonated in dry Ottawa sand. Charge configurations for these events ranged from 5-charge-radii height of burst to 15-charge-radii depth of burst. The techniques required to maintain a well characterized 'standard' sandbed were developed and employed for two series of experiments. The 'standard' sandbed was chosen to be that with an in-situ density of 1.801 gm/cc. The main or Overall Series of experiments was conducted in the 'standard' sandbed to determine the relationship between apparent crater size and charge configurations. Realistic levels of reproducibility for various cratering experiments, in terms of apparent crater dimensions, were determined by conducting a Benchmark Series of experiments.
