Abstract: A mechanical actuator is disclosed. The mechanical actuator can comprise an interface portion configured to interface with an object, a spring configured to exert a force on the interface portion, and a shape memory member coupled to the interface portion. The shape memory member can be configured to fracture at a predetermined temperature range. Upon fracture of the shape memory member, the force of the spring can cause the interface portion to act on the object.

Abstract: An integrated warhead and rocket motor subassembly. The novel subassembly includes a warhead, a rocket motor, and a single bulkhead separating the warhead and the rocket motor. The bulkhead is adapted to handle both pressure loads from the rocket motor and missile carry loads transmitted through a hook and hangar assembly, which is bolted into the bulkhead. In an illustrative embodiment, the warhead includes an explosive fill surrounded by a material adapted to form a plurality of fragments upon detonation. In a preferred embodiment, the fragments are formed into small cubes that are 80 to 85 grain in weight, using a material having a density greater than 16 g/cc.
