Spectroscopy of Propellant-Related Flames
Abstract
This report summarizes the progress made in solid propellant flame chemistry studies. This work involves LIF studies of OH, CN, NO, and C2. Success was achieved in laboratory flame studies, but was rare in solid propellant applications. Preliminary studies in a hydrazine/methane/nitrogen dioxide diffusion flame yielded emission spectra from OH, NH, CN, CH, and C2. The vibrational temperatures of the NH and CN were consistent with published mechanisms for chemiluminescent excitation. Chemical kinetic studies of high pressure propellant flame yielded inconclusive results because of gaps in the knowledge of the combustion mechanisms of important species such as CN and NO2. (jhd)
