Experimental measurements of thermally stimulated propellants can be used to improve predictive modelling and safe handling and storage procedures. The primary decomposition products of CMDB were examined using mass spectrometry for stable gas phase species and broadband absorption spectroscopy for condensable products such as water. Absorption spectroscopy was also applied to traditional double base, ammonium nitrate, and ammonium perchlorate propellants for comparison. The physical behavior of the propellant was captured using pressure diagnostics during the cookoff of confined samples in a sealed blast chamber and was compared to HMX and RDX detonations.
