Abstract

High mass and volumetric heat of combustion makes boron a promising component of solid fuel for ramjet-propulsion systems. Its application is limited by the complexity of the organization of combustion with a high effectivity. Experimental studies of single boron particles combustion demonstrate several unique features not specific for other materials: a variable ignition temperature, two combustion stages, a drastic reduction of the burning rate for particles size of several microns and less. Models that try to predict combustion rate in the entire range of temperatures, concentrations and particle sizes are not physically obvious, difficult to reproduce, and do not show desirable for real applications accuracy. A simple diffusion model of combustion of boron particles is proposed, it describes the combustion of 34.5 and 44.2 micron particles at temperatures above 2240 K with 20% error.
