Spectral Studies of Solid Propellant Combustion 2. Emission and Absorption Results for M-30 and HMX1 Propellants

Abstract

A windowed strand burner with a propellant feed mechanism has been used to characterize the steady-state burning of two composites propellants, M- 30 and HMXl, at moderate pressure. Both emission and absorption spectroscopy have yielded profile data on three important combustion species: OH, NH, and CN. Relative appearance of these three species are inferred from emission intensity profiles, and absolute concentration profiles are calculated from the absorption data. This is the first absolute determination of these combustion intermediates in a propellant flame. These concentration measurements for OH indicate that the propellant flame temperatures are about 200 K below adiabatic. A maximum value of 40 ppm NH is found for the M-30 propellant flame. Fluctuations in the flame front of HMXl compromised the determination of maximum concentrations for NH and CN. Keywords: Combustion; Solid propellant; Spectroscopy; Absorption; Emission; Concentration; Profiles; Solid propellants.
