Patent ID: 7546804

Claim:
An artillery charge that is ignited by a laser beam, comprising: a generally cylindrical body having a hollow core that is axially disposed within the body, along a path of the laser beam; wherein the hollow core includes a first end and a second end; a propellant disposed in the body, around the hollow core; a core igniter bag containing a core energetic material, wherein the core igniter bag is axially disposed relative to the body, inside the hollow core; a first end igniter bag that is generally co-axially disposed relative to the core igniter bag, inside the first end of the hollow core; wherein the first end igniter bag contains a first energetic material; a first seal disposed over the first end of the hollow core; the first seal having an internal surface; wherein the internal surface of the first seal forms a first pocket that is generally co-axially disposed relative to the first end igniter bag, at a distance from the first end igniter bag, inside the first end of the hollow core; a second energetic material disposed against the internal surface of the first seal, within the first pocket of the first seal; wherein the loser beam ignites the second energetic material for reducing the scattering of the laser beam; wherein the ignited second energetic material, in turn, ignites the first energetic material inside the first end igniter bag; wherein the ignited first energetic material, in turn, ignites the core energetic material inside the core igniter bag; and wherein the ignited core energetic material, in turn, ignites the propellant.
