SELF-DESTRUCT FUZE DELAY MECHANISM

摘要

An exemplary self-destruct fuze delay for a submuntion 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. Initiation of the secondary detonator destroys the primary detonator and, depending upon slide location, either sterilizes the submunition, or destroys the entire submunition.
