  • Patent number: 8222583
    Abstract: A drag-stabilized water-entry projectile having a projectile body, one or more drag-stabilizing elements, such as fins, flares or canards, and one or more attachment members adapted to hold the one or more drag-stabilizing elements to the projectile body. The one or more attachment members are coated with a thermally reactive material. A projectile and cartridge assembly has a shear pin, a projectile having a first cutout portion, the cutout portion sized to receive the shear pin. The assembly also includes a sabot configured to house the projectile and having a second cutout portion, the second cutout portion sized to receive the shear pin. The cutout portion is positioned to provide an offset region between an aft end of the projectile and a base of the sabot.

  • Patent number: 8093487
    Abstract: A removable protective nose cover for a submersible structure having a nose section is disclosed. The removable protective nose cover can include a plurality of shell members, each of the shell members having a forward end and an aft end. Each shell member can also be dimensioned to fit adjacent to and around the nose section of the submersible structure and thereby form a protective shell. A central nose member having a locking member can also be included, the locking member being operable to attach the central nose member to each of the forward ends of the shell members. The aft ends of the shell members can be attached to each other using a plurality of attachment clips such that the attachment of the central nose member to each of the forward ends of the shell members and the attachment of the adjacent aft ends of the shell members form the removable protective nose cover for the submersible structure.

  • Patent number: 6802260
    Abstract: A safety and arming device has first and second portions of an explosive train fixably supported in a housing. A third portion of the explosive train is fixable in a first position such that the first and second portions remain operably separated from one another, and is further movable to a second position such that the first and second portions are operably coupled to one another via the third portion. An integrated water sensor/actuator is coupled to the third portion to provide the motive force that moves the third portion to its second position. The water sensor/actuator is based on a fibrous cellulosic material having anisotropic moisture-absorbing properties such that dried-in strain of the cellulosic material is greatest along one axis thereof. In the invention, a plug of the dry and compressed fibrous cellulosic material has a powder material coated thereon and mixed therewith.

  • Patent number: 5955698
    Abstract: A supercavitating water-entry projectile having empennage on the aft end ch provides both aerodynamic and hydrodynamic stability and a supercavitating nose section is provided. A representative projectile is a subcaliber munition adapted for use in a 25 mm weapon using a sabot currently in use with the M919 round. The projectile has circumferential grooves around its center section to match these sabots. A key feature in the invention is the size and shape of the nose section. The projectile has a novel high strength extended blunt nose section followed by a truncated conical section which angles towards the body of the projectile in the range of five degrees. During underwater trajectory, the entire projectile is contained within the cavitation bubble formed by the blunt nose tip. The projectile's aft empennage, which provides both aerodynamic and hydrodynamic stability, fits within the bore of the weapon.

  • Patent number: 4788914
    Abstract: A nosepiece for the forward end of a missile that is launched into the atmosphere for a ballistic trajectory and a water entry impact comprises a frangible base and a separable nosecap, the base having multiple segments of rigid foam defining an axial bore into the base and a volume of soft cellular foam within the bore to protect the forward end of the missile. The nosecap is in seated relationship within the bore opening on the tip end of the base during airborne flight and separates therefrom to expose the axial bore opening prior to water entry impact such that upon impact the base is fractured by the force of water entering the exposed bore and thus separated from the missile.

  • Patent number: 4478148
    Abstract: An underwater communication system capable of being delivered by a missile or detonating a plurality of charges in a timed sequence. The system includes a main power supply, decelerometer means, separation switch means for electrically interconnecting and energizing the decelerometer means and said main power supply upon receipt of an arming signal from the missile, thermal battery means, means coupled to said decelerometer means for deploying a parachute and for energizing the thermal battery means, timer means for releasing the explosive charges in a predetermined sequence and means couples to the thermal battery means for energizing the timer means.

  • Patent number: 4433626
    Abstract: An underwater missile for use against submerged submarines has a missile housing with a magnetic contact surface (2) at a foremost end portion intended to contact a submerged submarine. The magnetic contact surface is provided by two magnets (2',2") located in adjacency and with reversed magnetic polarity. A magnetically operated switching means (5) is positioned adjacent to the magnetic leakage field of the magnets, and is arranged to be operated when the leakage field is increased by means of a metallic object located within the magnetic field of the magnets. The operation of the switching means first detonates a small propellant charge (6) to impose a force to cause complete adherence between the magnetic contact surface of the missile and the outer surface of a contacted submarine, and then detonates a main explosive charge (7) intended to penetrate the submarine.
