Abstract : This report covers research performed on the self-deflagration of hydroxylammonium perchlorate, the general objective of which was to gain some understanding of the combustion process. The experimental work included measurements of the pressure dependence of the deflagration rate, flame temperature, quenching diameters, and inflammability limits. A summary of the significant results of all the solid oxidizers studied is included, and an analysis of the combustion of these monopropellant-type oxidizers is given. The physical and chemical kinetic processes beneath, at and in the gas above the surface of the solid are considered, the concept of cellular flame structure is discussed, and inflammability limits are analyzed. A study was also made of the extinguishment of propellants by rapid depressurization. A laboratory scale extinguishment apparatus was developed which was essentially a modified optical strand burner. Three candidate composite propellants were selected for study and the results compared with extinguishment theory. An experimental study of the explosive decomposition of chlorine dioxide was also performed. The results of the ClO2 study together with an extensive interpretation of the reaction are presented.
