Patent number: 7743707Abstract: An explosive structure of the fragmentation type includes an outer casing comprising an energy dense explosive material and having an inner surface defining a chamber and means for propagating shock waves across the inner surface from a selected one of at least first and second detonation points within the casing. The explosive structure further includes first means for directing shock waves, propagated from the first detonation point, against at least a selected portion of the inner surface in a first pattern for scoring and weakening the casing along first, segment-defining lines and second means for directing shock waves, propagated from the second detonation point, against the selected portion of the inner surface in a second pattern for scoring and weakening the casing along second, segment-defining lines, the segments of the second pattern being larger than the segments of the first pattern.Type: GrantFiled: January 8, 2008Date of Patent: June 29, 2010Assignee: Lockheed Martin CorporationInventors: Roger W. Melin, Edward W. Sheridan

Patent number: 7656989Abstract: A plasma antenna generator includes an ionizable material, an explosive charge capable of projecting the ionizable material upon detonation, and a detonator coupled with the explosive charge. An electromagnetic pulse transmitting system includes an electromagnetic pulse generator and a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator. A method includes providing an explosive device comprising an ionizable material, detonating the explosive device to propel the ionizable material, and ionizing the ionizable material to form at least one plasma trail. A sensing system includes an electromagnetic pulse generator, a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator, and a sensing system capable of receiving and analyzing at least a portion of the electromagnetic pulse after being reflected from an interface.Type: GrantFiled: November 29, 2004Date of Patent: February 2, 2010Assignee: Lockheed Martin CorporationInventors: James R. Wood, Roger W. Melin, Mark K. Browder, Steve E. Calico

Patent number: 7340025Abstract: A plasma antenna generator includes a ceramic portion including an ionizable material, an explosive charge adapted to project at least part of the ceramic portion upon detonation at a velocity sufficient to ionize the ionizable material, and a detonator coupled with the explosive charge. A plasma antenna generator includes a housing defining a plurality of openings therein and a plurality of shaped charge devices or a plurality of explosively formed projectile devices received in the openings. Each of the devices includes an explosive charge, a detonator coupled with the explosive charge, and a ceramic liner, the ceramic liner comprising an ionizing material. A method includes providing an explosive device and a ceramic portion comprising an ionizable material disposed proximate the explosive device, detonating the explosive device to propel the ceramic portion, and ionizing the ionizable material to form at least one plasma trail.Type: GrantFiled: April 1, 2005Date of Patent: March 4, 2008Assignee: Lockheed Martin CorporationInventors: Roger W.
