  • Patent number: 5054399
    Abstract: An ordnance or munition casing is described which comprises a hollow outer casing having a shock attenuating inner liner made from successive layers of material of inwardly decreasing acoustic impedance. The inner liner reduces the sensitivity of the munition to sympathetic detonation and cookoff. Also described is an attenuation barrier made from a layer or layers of less detonation sensitive explosive material. The layers of less detonation sensitive material are preferably arranged in successive layers of outwardly decreasing detonation sensitivity. The same layers may combine sequenced acoustic impedance and detonation sensitivity. The layers may be made of material compounded with flaked or granular materials to provide preselected acoustic impedances. A coating for desensitizing the outer surface layer of a main explosive charge is also disclosed.

  • Patent number: 4878415
    Abstract: The presention of sympathetic detonations between donor and acceptor bombs, which are stored lying horizontally parallel to each other, is accomplished by storing these bombs on a bomb storage pallet with a plurality of enclosed tubes which extend along the length of the bombs, and which are filled with fire suppressant chemical extinguishing agents. Additionally, shielding is provided to the stored bombs with diverters which block fragments in the event of a detonation, and which have a sufficient width to attenuate propagating shock to a level below a threshold at which sympathetic detonation occurs. The bomb pallet assembly has a horizontal base to which a frame is fixed. This frame holds the diverters in place and can have enclosed tubes of fire quenching agents within its structure, including its outer walls. Additionally the diverters each have a central aperture to hold similar enclosed tubes of fire quenching agents.

  • Patent number: 4711177
    Abstract: An auxiliary booster is used to relay and amplify the detonation wave from a standard configured bomb. An explosive system is placed in an extended fuse well to interface with the main charge. The auxiliary booster is initiated as a second, sequential event by this conventional booster charge. Energy of the conventional booster is transmitted into the auxiliary booster charge and the combined energy of the two charges is focused on the auxiliary charge's tapered metal liner. This tapered metal liner is driven through an air gap into the end of the fuse well at hypervelocity. The design of the device provides controlled packaging of energy for the generation of vaporific effects resulting in the collision of the metal liner of the auxiliary charge with the metallic end of the fuse well for enhanced detonation of the main charge.
