Fuel-rich solid propellant boron combustion. Final report, 1 April 1982-31 March 1983
A unified single boron particle ignition/combustion/ extinguishment model capable of treating the effects of various oxidizers, Finite-rate kinetics, and time-dependent environmental conditions has been developed and successfully checked against historical data bases. In addition, parts of this model have been combined with enthalpy and species conservation equations for analysis of boron combustion efficiency in an idealized slurry ramjet combustor (perfectly stirred reactor followed by a series of incremental plug-flow reactors with arbitrary air addition as a function of operational and design parameters). Cibsuderabke subgke particle ignition/combustion data have been obtained over a wide range of particle sizes (5-70 Microns) in wet atmospheres with this experimental effort currently being extended to dry atmospheres. An experiment to determine the kinetics of the boron oxide-water reaction (crucial to ignition) is in progress. A laboratory apparatus for studying combustion of highly-boron-loaded solid fuel ramjet grains in hot air crossflow on a fundamental basis has been completed. Design of a well-stirred reactor for study of boron cloud and slurry combustion is complete and equipment fabrication is underway.
