    Abstract: A heat-activated triggering device, such as for a missile or munition, includes a bi-metal trigger element, with a breakable pin of a first metal surrounded by a sleeve made of a second metal that is different than the first metal. The sleeve may be made of a shape memory alloy, such as a single-crystal shape memory alloy, that is pre-compresses around part of the pin. The sleeve may be configured to put a tension force on the pin as the sleeve passes a predetermined temperature, for instance a temperature at which the shape memory feature of the sleeve is activated. The pin may have a weakened portion, such as a notched portion, at which the pin breaks. The breaking of the pin may be used to drive a firing pin into a primer, to initiate a detonation and/or combustion reaction.

    Abstract: A heat-activated triggering device, such as for a missile or munition, includes a firing pin that is driven into a primer, to initiate a detonation and/or combustion reaction. The firing pin may be mechanically coupled to a linkage that prevents egress of output from the primer if the firing pin has not been moved. The linkage may include, for example, a cylindrical valve element with a through hole, the through hole being alignable with an output channel from the primer when the firing pin has been moved sufficiently. The movement of the firing pin slides a dowel pin that is attached to the firing pin. This in turn translates a cam element that turns the cylindrical element. Partial movement of the firing pin still may leave the valve closed. Preventing the primer from prematurely operating to trigger explosion, for example preventing full operation due to a primer being heated.
