Abstract

A multichannel infrared absorption technique has been developed and applied to the study of solid propellant flames. Infrared absorption spectra of HCN, H₂CO, CH₄, CO, CO₂, N₂O, and H₂O have been obtained in the dark zone of solid propellant flames during steady state combustion conditions through the use of a 1024 element platinum silicide (Pt-Si) array detector. The experiment consists of a quartz tungsten halogen lamp as the source, a 0.320 m spectrometer with a 75 grooves/mm grating, the Pt-Si array detector and a windowed strand burner where cylindrical propellant samples are burned cigarette fashion in the presence of an inert buffer gas. Results for a nitramine propellant M43 are presented along with estimates for the temperature and species concentrations through the use of the HITRAN database and associated PC programs.
