Propulsion and Energetics/Energetic Materials: Optical Characterization of Subsurface Reactions in Heterogeneous Materials
Abstract
Energetic materials can be initiated through a variety of stimuli, including thermal, mechanical, andelectrical means, with the non-thermal stimuli believed to generate heat first which then causes thermally-induced chemical decomposition. Optimizing the performance of energetic materials for specific applications must be balanced against safety and reliability considerations. This process requires an improved fundamental understanding of the chemical reactions inside the material. Our long-term goal is to develop and demonstrate the experimental feasibility to monitor in real-time subsurface chemical reactions in scattering heterogeneous materials.We then plan to use this capability to investigate and characterize subsurface chemical reactions in energetic materials. Our initial focus is on developing and demonstrating the experimental capability to focus a laser beam inside a scattering heterogeneous medium and to perform Raman and LIF measurements at the focal spot.
