Patent ID: 7587978

Claim:
An initiator for a munitions device that contains an explosive within a case, the device having a trajectory direction, the device intended to strike a target substantially along the direction, the initiator comprising: a sleeve within the case and adjacent to the explosive, said sleeve defining an initiator interior aligned substantially parallel to the trajectory direction, said sleeve including at least one orifice that extends therethrough between the explosive and said interior; an initiation pellet within said interior, said pellet being composed of a reactive material that chemically responds as a non-explosive to kinetic and thermal stimuli, said pellet being disposed adjacent said orifice; a first anvil disposed transverse to said interior and forward of said pellet; and a second anvil disposed within said interior behind of said pellet, wherein said second anvil translates within said interior towards said first anvil substantially along the trajectory direction in response to the device striking the target, said pellet discharges particles through said orifice into the explosive in response to said second anvil translating towards said first anvil.
