Advanced high-speed spectroscopy for energetic materials
Abstract
The advancement of Department of Defense capabilities requires detailed knowledge in the mechanisms and chemistry involved in the rapid, controlled release of energy from energetic materials. The use of advanced diagnostic approaches provides information about the microstructure, composition, and performance of energetic materials by interrogating the chemical makeup of the energetic material and the products produced during combustion. This project expands existing capabilities by expanding the temporal resolution of diagnostic approaches to enable the direct study of high-speed combustion and detonation phenomena.The objective of this proposal is to acquire and integrate advanced spectroscopy hardware to enable unique facilities to determine physics governing the composition, reaction, and performance of energetic materials relevant to DoD interests. The equipment includes high-speed acquisition hardware and detectors capable of interfacing with laser spectroscopy systems and existing highspeed instrumentation spanning from the x-ray to infrared wavelength ranges. The equipment will support ongoing efforts in (1) characterizing detonation fireballs, (2) informing fundamental physics during active throttling of solid propulsion systems, and (3) characterizing liquid atomization process with x-ray imaging techniques. The equipment will also be utilized in future work in characterizing tunable pyrotechnic emissions, and determining the sensitivity of porositymodifiable energetic materials.Integration of this spectroscopy hardware with existing unique laser sources, detonation experimentation, and x-ray imaging experiments at Iowa State University will enable fundamental discoveries in application of control techniques for spray breakup, detonation properties, and energetic material performance. These complementary capabilities will advance the state-of-the-art diagnostic approaches across a wide wavelength range, resulting in far-reaching impact on current and future projects within DoD.
