A propellant-charge pack has an annular envelope having an outer wall extending along and centered on an axis, a pair of axially spaced end walls extending transversely inward from the axis and having inner peripheries centered on the axis, and an inner wall defining a clear axially throughgoing passage between the inner peripheries of the end walls. The envelope is generally axially symmetrical about the axis, that is it is formed as a body of revolution or of regular polygonal section, and is substantially symmetrical to a plane perpendicular to the ax...
A propellant-charge module with a primer charge and a pair of opposite ends and a combustible envelope, comprising in combination, (a) the propellant-charge module having a coaxial clear detonating passage extending over its entire module length; (b) said detonating passage being mainly formed by the primer charge and being symmetrically arranged with respect to the end walls of said module; (c) the inner diameter of the detonation passage being such that the propagation of the ignition blast along the entire length of the charge is faster than that prop...
