Combustion Spectroscopy by Pumped Dye Laser.

Abstract

This report describes a pumped dye laser system used in studies of the combustion of nitramine based solid rocket propellants. Although these propellants have advantages of high specific impulse and low infrared and smoke emissions from their exhaust, better control of the burn rate is needed. Propellant additives have been suggested for burn rate control but the understanding of the chemical mechanism of burning is not well enough developed to predict the effects of these burn rate modifiers. The objective of our studies is to describe the detailed chemistry of reactions of gas phase species which are important in the combustion of nitramine propellants and additives. Species composition, temperature and burning rate have been measured for reacting gas mixtures representative of the pyrolysis products of nitramines and nitramines with additives. Chemical kinetic and fluid mechanic modeling of the flame structure is used to correlate the experimental data and evaluate critical reaction paths and energetics and their importance in burn rate control.
