Changing of ballistic parameters from aged gun propellants
conference paper
The various properties of an SB and a DB gun propellant were investigated before and after artificial ageing. It was found that the decrease of nitrocellulose (NC) molecular weight, due to ageing of gun propellants, leads to a decrease of the mechanical integrity of the propellant grains. The effect of grain fracture on the peak pressure was found to be strongly related to the loading intensity. It was suggested that a relation exists between grain fracture and NC molecular weight, which describes that propellants become more brittle when the NC chain length decreases.
