Detonation and Blast Wave Characteristics of Nitromethane Mixed with Particles of an Aluminium–Magnesium Alloy

Investigation of detonation parameters, blast wave characteristics and quasi‐static pressures (QSPs) for the mixtures of nitromethane and particles of an aluminium and magnesium (Al₃Mg₄) alloy was carried out. The mixtures of gelled nitromethane containing 15–60 wt.‐% Al Mg alloy were tested. Detonation velocity and Gurney energy were determined. Parameters of blast waves produced by charges of the investigated explosives were measured. QSP measurements were conducted in a steel chamber of 0.15 m³ volume filled with air. Thermochemical and gasdynamical calculations were also performed. The degree of combustion of the metallic addition with the gaseous products during detonation and expansion is discussed.
