Abstract : The objective of this work is to determine the chemical mechanisms of solid propellant ignition and deflagration with an emphasis on the decomposition of individual propellant ingredients and on the gas phase reactions of the products of decomposition. A quadrupole mass spectrometer system using quartz microprobes measures species profiles above the surface of the sample during CO2 laser induced pyrolysis or during laser assisted deflagration of the sample. In addition microthermocouples are used to measure the surface temperature and gas phase temperatures during testing. To complement the experimental studies, chemical kinetic models produced by other researchers are used to model some of the data obtained. jg p.4
