ABSTRACT:
A propellant charge is assembled by stacking together a plurality of extrd longitudinally grooved polygonally shaped high packing density propellant grains. An hexagonal configuration provides for nearly full utilization of the circular volume of a propellant chamber. Selective location of a plurality of perforations and grooves through each grain member is used to provide propellant charge assemblies having uniform web distribution and improved burn characteristics.
