Paper 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.
