Abstract (en)
[origin: WO2017004726A1] The present application relates to a propellant charge system for firing artillery shells comprising at least two partial charges. The partial charges each have one type of powder, which comprises nitrocellulose, at least one crystalline energy carrier and at least a first inert plasticiser. At least one partial charge has a first type of powder and the at least one further partial charge has a second type of powder. The second type of powder has between 2 and 10 percent by weight of a second inert plasticiser in the region of zones near the surface, to a maximum depth of penetration of 400 micrometres, while the first type of powder has no second inert plasticiser in zones near the surface.
