(DURIP) URI EXPLOSIVE EQUIPMENT REPORT
Abstract
The University of Rhode Island (URI) Energetic Materials Lab conducts a number of studies on military projects. To support that work, three instruments are requested. 1) New energetics materials and formulations introduce heterogeneity on the micron and nanometer scale. Smallscale experiments have been done to aid development of models to predict performance at munition scale. Munitions and their compositions can be modeled using multiphysics codes such as those developed by national labs (ALE3D or CTH), but the number of elements and resolution of any models generated are limited severely by the computational bandwidth available. To achieve the resolution needed by our projects a graphics processor unit (GPU) accelerated computation server is requested. 2) As most of our projects require modeling, most also require explosive field testing. We generally do small elegant tests using photon Doppler velocimetry (PDV) to follow detonation in the explosive formulations of interest. The PDV light path between the control room and the device goes through a number of connections. To increase the throughput and reliability of experiments, we request an Optical Frequency-Domain Reflectometry (OFDR) system to determine light lost via reflections at each interface. 3) The URI Energetic Materials Lab also strives to improve explosive analysis and detection. To aid in the development of new detection instrumentation by increased understanding of the ionization potential of various energetics, we request a differential ion mobility spectrometry (DMS) which is designed to attach to the high-performance mass spectrometer already present in our lab.
