Medium-caliber cartridge munition used for practice, includes passages through casing from chamber containing propellant charge, which are filled with melting alloy

摘要

Passages (14) originate from the chamber (4) containing the propellant charge. These penetrate the cartridge casing (3). They are filled with a solid, pressure-tight material (15) capable of being melted. The melting point is lower than the ignition temperature of the pyrotechnic ignition device (13) and the propellant charge (5) of the munition.
