  • Publication number: 20120037028
    Abstract: A fuze mechanism for a submuntion includes an activation mechanism having a container filled with an activation fluid and an ampoule breaker to break the container upon deployment of the munition, a delay mechanism including a spring-loaded self-destruct firing pin to initiate a secondary detonator in close proximity to a primary detonator, and an interlock unit supported by the ampoule breaker that locks the self-destruct firing pin away from the secondary detonator. The ampoule breaker includes a piston and a timing ball, which accesses the activation liquid. The action of the activation liquid on the timing ball over time causes the timing ball to erode until it is forced into the container by the spring-loaded piston. The movement of the piston frees the interlock unit, allowing the spring-loaded self-destruct firing pin to move under force and impact or initiate the secondary detonator.

  • Patent number: 7530313
    Abstract: An exemplary self-destruct fuze delay for a submunition includes a container filled with an activation fluid, a spring-loaded ampoule breaker to break the container upon deployment of the munition, a spring-loaded self-destruct firing pin to initiate a secondary detonator in close proximity to a primary detonator, and an interlock ball supported by the ampoule breaker that locks the self-destruct firing pin away from the secondary detonator. The ampoule breaker includes a piston and a timing ball, which accesses the activation liquid. The action of the activation liquid on the timing ball over time causes the timing ball to erode until it is forced into the container by the spring-loaded piston. The movement of the piston frees the interlock ball, allowing the spring-loaded self-destruct firing pin to move under force and impact or initiate the secondary detonator.

  • Patent number: 6901835
    Abstract: An extractor and method for safely releasing an explosive and liner from a munition is disclosed. An exemplary extractor includes a support device connected to the casing of the munition and adapted to stabilize the munition as the explosive is released from the dome end of the munition casing and a fluid port adjacent the dome end of the casing and adapted to introduce a high pressure fluid through the dome end to the explosive to separate and release the explosive from the dome end. An exemplary method for releasing an explosive and liner from a dome end of a munition casing includes inserting a fluid port into a dome end of the casing and introducing a fluid through the fluid port to the explosive to release and separate the explosive from the dome end and to shear the mechanical coupling between the liner and the casing.
