The internal and external detonation characteristics of nitromethane and aluminum powder mixtures were investigated. Nitrogen dioxide was added in order to vary the oxygen balance in the combustion reactions. The experimental results indicate the existence of a maximum detonation velocity in the vicinity of stochiometric compositions. A pressure drop associated with energy absorption due to the melting of the metal is also observed together with a subsequent progressive increase in pressure corresponding to the combustion of the metal. The kinetic energy released during the delayed aluminum combustion was determined from the expansion work of the reaction products.
