A spherical warhead is disclosed which yields a greater than 120.degree. ped charge of preformed fragments and which further permits non-destructive cook-off of explosives to prevent undesirable detonation.

Spherical warhead

A shaped charge that relates generally to metal moving warheads and which s as an improvement a means of increasing the explosive energy in a metal moving warhead by providing an air gap between the explosive and the metal to be displaced thereby providing, upon detonation of the explosive charge, the formation of a high velocity jet of intensified energy that makes a superior shaped charge device for use in piercing or deforming solid material.

Shaped charge

A metal cup encloses layers of armoring material to enhance the penetration esistance of a guided missile warhead to mechanical countermeasures. A layer of ceramic material is inserted in the cup followed by the insertion of at least one pair of layers consisting of a layer of metal backed by a layer of polymethylmethacrylate. The metal cup is attached to the forward end of a missile warhead section and the exterior of the cup is conformal with respect to the exterior of the warhead section. The layered materials act to blunt or break incoming projectiles, absorb their kinetic energy, and prevent their penetration into the interior of the warhead.

Armor penetration resistance enhancement

A blast attenuator device is disclosed comprising a collapsible/inflatable cylinder for containment of a body of foam therein. The cylinder is provided with a slitted floor such that the explosive device to be contained can be inserted therethrough. The blast attenuator is self contained and is provided with a compressed gas cannister for inflating the cylinder and foam generating cannister for automatically dispensing foam into the cylinder. The blast attenuator device can be deflated and compactly rolled up from a cylinder eight feet in height and eight feet in diameter to a bundle approximately four feet long for convenient storage and transport. Once the blast attenuator has been unpacked and placed over the explosive device, the inflating device can be turned on, the cylinder automatically inflates, and the foam cannister automatically dispenses foam after cylinder inflation to a specified height.

Blast attenuator

A new, lightweight armor plating for important installations or control cers is disclosed whereupon being struck by a projectile restricts the ensuing shock wave to a narrow beam-like path always perpendicular to patterns of striation engrained in said armor. This response dissipates the projectile's kinetic energy more rapidly. The new armor is lighter than traditional forms of armor.

Armor

A continuous rod warhead which utilizes ribbon shaped rods plug welded toher at alternate ends to form a continuous rod bundle is used in terrain clearance. The warhead may either be dropped from an aircraft and contact exploded or hand placed and then exploded by any convenient means.
