Dynamic Airblast Simulator (DABS) Instrumentation Development. Phase II.
Abstract
Development of explosives-driven nuclear blast simulators requires instrumentation for measurements to characterize blast flow. In a series of field tests with a large shock-tube-like dynamic air-blast simulator (DABS) blast flow characterization is attempted through measurements of parameters related to dynamic pressure. Doppler radar and infrared thermometry techniques are described toward determination of detonation product interface velocity. Blunt face drag body and acoustic techniques are implemented toward determination of flow Mach number. Other measurements include high stress and particle velocity in the walls of the explosives driver chamber using manganin sensors, conduction pins, and a mutual inductance particle velocimeter. Results of the measurement implementations indicate the soundness of the technical approaches for measurement techniques in the extremely hostile blast flow environment. (Author)
