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. Respective ignition means are disposed externally of the barrel for igniting the discrete propellant charges, and ignition apertures through the barrel are disposed at positions between adjacent projectile heads and provide communication between the externally disposed ignition means and the respective discrete propellant charges. A controller selectively and sequentially actuates the ignition means.
