Abstract
A unitary propellant charge module for use in separate ammunition comprises a combustible container having a generally hollow cylindrical shape, a generally cylindrical charge body of interconnected compacted spheroidal propellant grains disposed within the container, each of the grains having an uncompacted propellant grain diameter of at least 100 mils, and at least one generally tubular center core igniter body of interconnected compacted spheroidal propellant grains having an unrolled grain size between about 20 to less than 100 mils in diameter. The igniter body is disposed within a central bore extending along the longitudinal axis of the charge body.
Claims27
A unitary propellant charge module adapted for use as a main charge body in large caliber guns requiring separate ammunition to provide improved barrel life and permissible rates of fire, said body being capable of generating an average flame temperature of about 2700.degree. K., said module comprising:
- a porous self-supporting charge body of interconnected solid compacted spheroidal smokeless propellant grains, each of said grains having an uncompacted propellant grain diameter of at least 100 mils, said body generating a mean gun gas temperature of less than 2000.degree. K. during ignition of said charge module.
The module according to claim further comprising a combustible casing enclosing said body.
