Multichannel Infrared (IR) Absorption Spectroscopy Applied to Solid Propellant Flames.

Abstract

A multichannel infrared (IR) absorption technique has been developed and applied to the study of solid propellant flames. Infrared absorption spectra of HCN, H20, N20, CO, CO2, and CH4 have been obtained through the dark zone of solid propellant flames during steady-state combustion conditions through the use of a 1,O24-element platinum silicide (PtSi) array detector. The experiment consists of a quartz tungsten halogen lamp as the source, a 0.320-m spectrometer with a 75-groove/mm grating, the PtSi array detector, and a windowed strand burner where cylindrical propellant samples are burned cigarette fashion in the presence of nitrogen buffer gas. Experimental results for the nitramine propellants XM39 and M43 and a double-base propellant JA2 are presented, and estimates for the temperature and species concentration are given through the use of the HITRAN database and associated PC programs. Comparisons are made between this work, other published measurements, and thermochemical equilibrium calculations.
