Abstract : The goal of the High Energy Density Matter Program of the Air Force, the development of a rocket propellant that significantly improves on the performance of the conventional liquid hydrogen/liquid oxygen rocket propellant, is an ambitious and important undertaking. The 'next generation' propellant must be energetic, economical, and safe from both an engineering and environmental standpoint. These properties are often mutually exclusive and a balance of availability and ease of use must be struck. Cryogenic solids, specifically 'energized' solid hydrogen and/or solid oxygen, have been an area of study for years. Using cryogenic solids, the increase in density gives rise to a modest increase in theoretical performance, but more importantly, cryogenic solids provide a low-temperature environment required for the stable trapping of energetic species. Obtaining large concentrations of energetic species even in this low temperature environment has proven difficult. One system where ton quantities of the reactant species can be manufactured is a system using a mixture of solid ozone/oxygen; this mixture is the focus of the research on this project.
