Reinforced propulsive charge - having blocks of propulsive powder reinforced longitudinally by central rods of metal or plastics material

摘要

Propulsive charge has a number of blocks of propulsive powder, each block being reinforced over its whole length by a central rod or core, so that the mechanical forces exercised on the charge are transmitted by the blocks to the reinforcing cores. Good resistance to impacts, vibrations and temp. variations. The blocks can be relatively thin, thus providing rapid combustion, and also relatively long, while retaining a good mechanical strength.
