Abstract:
1. A munition for use with a gun having a gun tube, comprising: a cartridge comprising a base member at one end and an adapter case at an opposite end; a solid propellant contained within a cartridge case of the cartridge; an electric primer affixed to the base member; a self-rupturing canister secured to the adapter case, wherein the solid propellant is disposed outside the canister, so that upon initiation of the propellant the canister is propelled through the gun tube; wherein the canister contains a payload, and is closed by a cap that retains the payload within the canister; wherein the cap is generally flat and is seated within a recess defined by an inner wall of the canister, relative to a forwardmost, open end of the canister, in order to create a high air pressure area acting against the cap and against the inner wall of the canister within the recess; wherein the electric primer is disposed within the propellant, away from the canister; wherein the canister further comprises a plurality of longitudinal grooves; and wherein the longitudinal grooves weaken the structure of the canister, so that during flight, the high air pressure area acting on the cap ruptures the cap, thus allowing air to enter the canister, and to induce an air pressure buildup that causes the canister to break apart at the longitudinal grooves and the payload to be dispersed.
