United States Patent | 7,546,804 |
Tartarilla, III , et al. | June 16, 2009 |
An artillery charge includes a generally cylindrical body with a hollow core; propellant disposed in the body and first energetic material disposed in the hollow core; and a seal disposed over one end of the hollow core, the seal including second energetic material disposed therein. A laser igniter ignites the second energetic material in the seal, thereby providing more reliable ignition of the first energetic material and the propellant. The artillery charge reliably ignites using a lower powered laser than known charges.
