Abstract
A propellant charge comprising a matrix of granular propellant having interspersed therethrough compacted molded bodies of propellant. The density of the granular propellant is less than the density of the molded propellant bodies. The use of the mixed propellant charge enables a cartridge case of given dimensions to be loaded with a greater weight of propellant thereby enabling the achievement of greater projectile velocities in any given gun-ammunition system.
Claims8
A propellant charge for use in a cartridge, said propellant charge comprising a first constituent of compacted nitrocellulose base smokeless powder and a second constituent of loose granular nitrocellulose base smokeless powder, said propellant charge having a maximum packing density which is greater than about 1.0 gm/cc.
A propellant charge for use in a cartridge, said propellant charge comprising a plurality of compacted bodies of nitrocellulose base smokeless powder dispersed in a matrix of loose granular nitrocellulose base smokeless powder, said propellant charge having a maximum packing density which is greater than about 1.0 gm/cc.
A propellant charge for use in a cartridge, said propellant charge comprising a plurality of compacted bodies of nitrocellulose base smokeless powder substantially homogeneously dispersed throughout a matrix of loose granular nitrocellulose base smokeless powder to form a mixture having a maximum packing density which is greater than about 1.0 gm/cc.
A cartridge comprising a casing, a projectile in said casing, a primer, and a propellant charge disposed in a chamber within said casing, said propellant charge including a first portion of compacted nitrocellulose base smokeless powder and a second portion of loose granular nitrocellulose base smokeless powder, said propellant charge having a maximum packing density within said casing chamber which is greater than about 1.0 gm/cc.
A cartridge comprising a casing, a projectile secured to said casing, a propellant chamber in said casing adjacent said projectile, and a propellant charge within said propellant chamber, said propellant charge including a plurality of compacted bodies of nitrocellulose base smokeless powder dispersed in a matrix of loose granular nitrocellulose base smokeless powder, and said propellant charge having a maximum packing density which is greater than about 1.0 gm/cc.
A cartridge comprising a casing, a projectile secured to said casing, a propellant chamber in said casing, and a propellant charge in said propellant chamber, said propellant charge comprising a plurality of molded bodies of nitrocellulose base smokeless powder substantially evenly dispersed throughout a matrix of loose granular nitrocellulose base smokeless powder, said propellant charge having a maximum packing density of greater than about 1.0 gm/cc.
