  • Patent number: 6889935
    Abstract: A missile includes one or more arrays of barrel assemblies that are displaced from the centre of gravity of missile. Each barrel assembly includes a plurality of projectiles axially disposed within a barrel, and each projectile is associated with a discrete propellant charge for propelling the projectile sequentially from the barrel. Each array of barrel assemblies is capable of selectively firing the projectiles from selected barrels, whereby the missile is accelerated by the reactionary force generated by said firing of projectiles and the missile is deflected onto a new course or trajectory. This enables the missile to be steered to intercept its target, even if the target is undertaking evasive manoeuvres. Each barrel assembly may include multiple projectiles.

  • Patent number: 6543174
    Abstract: A barrel assembly (70) comprising a plurality of projectiles (75) axially disposed within a barrel (71) and associated with discrete selectively ignitable propellant charges (74) for propelling the projectiles from the barrel. The essence of the invention is the provision of a pressure relief valve, for example comprised by a port (73) and plug (76), associated with a chamber in which a propellant charge (74) is ignited. The pressure relief valve (73, 76) is designed to prevent catastrophic failure of the barrel (71) by exhausting via a chamber (72) in the event that the barrel is blocked by a projectile and detonation of one or more propellant charges (74) occurs.

  • Patent number: 6223642
    Abstract: A projectile firing weapon for firing rounds of the type having a projectile and an associated bore seal which is radially expanded by relative axial displacement between the projectile and the bore seal. The weapon includes a barrel assembly having a barrel bore, a barrel chamber for the round to be fired through the barrel bore, and an associated breech chamber for the next round to be fired. A propellant chamber is formed in the barrel assembly between the barrel chamber and the breech chamber, and a feeder feeds propellant into the propellant chamber. Rounds may be fed axially and sequentially through a loading opening to the barrel assembly and into the breech chamber, thereby forcing the existing round therein into the barrel chamber. Holding means cooperable with the round fed into the breech chamber effect a sealing relationship between the breech chamber and the round therein, causing an operative closure of the barrel chamber. An igniter ignites propellant in the propellant chamber.

  • Patent number: 6138395
    Abstract: A barrel assembly (10) having a plurality of projectiles (11) stacked axially within the barrel (12) together with discrete selectively ignitable propellant charges (13) for propelling the projectiles (11) sequentially through the muzzle of the barrel (12) is provided with adjacent projectiles (11) separated from one another by locating means (13) independent of the projectiles. The locating means may be a solid propellant charge (13) located between adjacent projectiles or it may be a rigid casing (122) for the propellant. When subject to an in-barrel load a rear skirt portion of the active projectile (11) is expanded outwardly by the interaction between an inwardly reducing recess (14) formed in the rear end of a projectile and the nested complementary leading portion of the propellant charge (13) or propellant casing (122).

  • Patent number: 6123007
    Abstract: A barrel assembly includes a barrel and a plurality of projectile assemblies disposed in end to end abutting relationship within the barrel and forming a compression resistant column of projectile assemblies. Each projectile assembly includes a projectile head and a spacer assembly engaged therewith and extending axially therefrom to abu the adjacent projectile assembly. Complementary wedging surfaces are disposed on the spacer assembly and projectile head, respectively, wherein relative axial engagement between a projectile head and its spacer assembly causes a radial expansion of the projectile head of wedging the projectile head into sealing engagement with the barrels. A discrete propellant charge is associated with each projectile assembly for propelling the projectile assemblies sequentially through the muzzle of the barrels.
