The objective of the present work has been to characterize the nature of the primary exhaust from fuel-rich motors containing boron, and to study its ignition and combustion characteristics, especially as compared to the known information for pure boron. Section II of the present report describes a the rocket-motor firing program in which the condensed exhaust CE from two different composite ammonium perchlorate propellants was collected, and b the results of thermodynamic computations for these formulations. Sections III and IV contain the results of the physical microscopy, density measurement and chemical analyses of the CE. Section V deals with combustion of the CE. Finally, Sections VI and VII report the results of modeling studies describing the ignition of single boron particles in hot gas streams and propagation of flames in boron-oxygen-nitrogen dust clouds.
