An ammunition tray is provided for containing a plurality of bullet cartridges within an ammunition box container having a stowage volume. The tray includes a substantially rectangular template having a horizontal surface bounded by first and second opposing longitudinal edges and opposing lateral edges joined at four corners. Each longitudinal edge includes a first tab bent substantially perpendicular to the surface in a vertical direction to form a rib. Each lateral edge includes a second tab bent substantially perpendicular to the surface to form a wall. The surface includes a first row of interior pockets that point towards the first longitudinal edge as a proximal orientation. The surface further includes a second row of interior pockets that point towards the second longitudinal edge as a distal orientation. The template has longitudinal and lateral edges bent to form the respective ribs and walls fits within the stowage volume as a vertical stack of plural templates. Each first interior pocket in the first row can cradle a cartridge on the surface along the proximal orientation, can fit the cartridge from an adjacent second row, and has lateral edges bent to curl in said vertical direction. Each second interior pocket in the second row can cradle the cartridge on the surface along the distal orientation, can fit the cartridge from an adjacent first row, and has lateral edges bent to curl opposite said vertical direction.

Process for making a fragmentation warhead using hot isostatic pressing where tungsten spheres, powdered steel, and interlock features on a mandrel are consolidated in a matrix. Then in the finished part, the front fragmentation cap, rear and interior geometries are machined, resulting in a finished warhead with an enhanced performance fragmentation cap integrally bonded to it.

An ammunition tray is provided for containing a plurality of bullet cartridges within an ammunition box container having a stowage volume. The tray includes a substantially rectangular template having a horizontal surface bounded by first and second opposing longitudinal edges and opposing lateral edges joined at four corners. Each longitudinal edge includes a first tab bent substantially perpendicular to the surface to form a rib. Each lateral edge includes a second tab bent substantially perpendicular to the surface to form a wall. The surface includes a first row of internal cutouts that point towards the first longitudinal edge as a proximal orientation. The surface further includes a second row of internal cutouts that point towards the second longitudinal edge as a distal orientation. The template has longitudinal and lateral edges bent to form the respective ribs and walls fits within the stowage volume as a vertical stack of plural templates. Each first internal cutout in the first row can cradle a cartridge on the surface along the proximal orientation and can fit the cartridge from an adjacent second row. Each second internal cutout in the second row can cradle the cartridge on the surface along the distal orientation and can fit the cartridge from an adjacent first row.

The invention comprises a continuous, integrated process to produce a multiple layered energetic material where the layers comprise energetic materials having, at least, two different burning rates. The process uses at least two twin-screw extruders to process at least two different energetic materials. These energetic materials are extruded into a co-extrusion die that, first, thins each energetic material flow into layers, and, then, combines the layers into a multiple layered energetic material. One embodiment of the invention also includes a remote take away system that completes processing the multiple layered energetic material after it leaves the co-extrusion die. The outer edges of the multiple layered material are first trim cut, then rolled into wrapped spools. Finally, the wrapped spools are cut into specified lengths for final use. These cutting, trimming and rolling steps are all done automatically, with no personnel handling required.

Co-extrusion of energetic materials using multiple twin screw extruders

An apparatus and method for selectively draining melt material, such as molten salt, utilizes an unobstructed drain conduit detachably connected, as by screw threads, to a vessel containing the material. Two heaters are utilized for the conduit, a drain heater at the vessel and a plugging heater spaced from the vessel. The conduit is placed at the plugging heater and partially filled with a predetermined quantity of plugging material in flowable form. The plugging material is, typically, the same salt in particulate form and is retained in the conduit by any suitable closure. The plugging heater is energized to melt the plugging material and is then de-energized so that a solid plug of this material forms in the conduit. The conduit, including the plug, is removed from the closure and the plugging heater and is connected to the vessel when the drain heater is de-energized and when the vessel does not contain molten melt material, as when the vessel is empty or this material is solidified. The molten material is then established in the vessel with limited heat transfer to the conduit so that the plug does not melt. When the melt material is to be drained, the drain heater is energized to heat the conduit and melt the plug so that the melt material drains through the conduit. When the conduit is suitably configured, such a quantity of the melt material may remain in the conduit to form another plug when the drain heater is de-energized.
