Design of the Condensed Phase Microstructure to Optimize the Performance of Propellants
Abstract
University of Illinois at Urbana Champaign (UIUC), California Institute of Technology (CIT), andUniversity of Missouri-Columbia (UM) propose a three-year continuation of a previously fundedeffort by AFOSR, to develop and apply methodologies to design the initial multi-componentmicrostructure of a propellant that will provide optimal performance. The proposed research willuse the tools developed in the previous effort (led by UM with CIT and UIUC) and optimizespecific impulse (and other metrics) in a "Strand Burner” configuration. The effort will usetopology optimization to maximize specific impulse and minimize mechanical stress, whileemploying state-of-the-art, tractable models for mechano-thermo-chemistry. Atomic-scalesimulations of the chemistry, phase transformations, and transport will support continuum-scalesimulations and microstructure optimization efforts. The predictions will be compared againstrelevant experimental data and system performance to provide confidence and concentrate thedesign optimization objectives to advanced, manufacturable propellant systems that can beconsidered for future propellant designs.
