  • Patent number: 8245640
    Abstract: Molten droplets of a metal fuel, such as aluminum, are dispersed into air or water for a reaction releasing energy for military or other purposes. In one warhead embodiment, a cylinder of solid metal is disposed within a ceramic heat insulator; heaters of thermite-like material are embedded in the metal; and an explosive dispersing charge is disposed around or at one end of the cylinder. On activation, the heaters are ignited to melt the metal, and the charge then detonated to disperse droplets of the molten metal. In a related embodiment, the metal and heaters are within a containment having an atomizing nozzle at one end and, oppositely of the metal from the nozzle, a piston and gas generator. When the metal is melted, the gas generator is activated to expel molten metal droplets from the nozzle.
    Type: Grant
