Patent number: 7854912Abstract: The crystal structure of three compositions of matter has been determined to be iso-structural with FeB ortho-rhombic (space group Pnma). The crystalline structures are: Ti0.5Ta0.5B, Zr0.5Ta0.5B and Hf0.5Ta0.5B. A process for preparing ceramics is disclosed. Molded ceramics including the compositions of matter are useful for applications such as rocket nozzles, leading edges on hypersonic missiles, engine parts and other applications requiring a structural component to operate at temperatures of 1600° C. to 2400° C.Type: GrantFiled: March 21, 2008Date of Patent: December 21, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: Inna G. Talmy, James A. Zaykoski, Adrienne H. Smith

Patent number: 7841290Abstract: In one general aspect, a shaftless external propulsion system as described herein provides a sleeve configured to be externally mounted over a hull of a marine vehicle. In addition, the shaftless propulsion system provides a rotor and a first stator mounted on the sleeve. The rotor includes a rotor hub that cooperates with a rotor bearing to enable the rotor to rotate about the sleeve, the rotor further comprising rotor blades attached to the rotor hub. The rotor and the first stator are disposed between a collar located at a first end of the sleeve and a collar hub located at an opposite end of the sleeve.Type: GrantFiled: February 12, 2007Date of Patent: November 30, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ronald P. Reitz, Gus F. Plangetis

Patent number: 7483671Abstract: In one general aspect, a communications system as described herein provides a wide-band jamming signal that is digitally created, conditioned, and modified by a processing based system to provide open data channels to authorized parties within a jammed communications band. The communications system modifies and maintains the open data channels to sustain communications between authorized devices. In addition, the communications system provides frequency hopping using the open data channels to supply secure data links to authorized devices within the jammed communications band while denying service to unauthorized communication nodes or devices.Type: GrantFiled: May 19, 2005Date of Patent: January 27, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Blaise L. Corbett, Michael L. Workman

Patent number: 7111521Abstract: A system for sampling a moving fluid utilizes a housing in the shape of an airfoil having a leading edge adapted to be disposed in the moving fluid such that the moving fluid will initially encounter the leading edge. A fluid flow pathway extends through the airfoil. One or more sampling ports are formed in the airfoil on the airfoil's high pressure side. Each sampling port is in fluid communication with the fluid flow pathway. The system can also have one or more control ports formed on the low pressure side of the airfoil. Each control port is in fluid communication with the fluid flow pathway. The housing can be mounted to experience two rotational degrees of freedom, and can have an aerodynamic tail assembly coupled thereto.Type: GrantFiled: May 19, 2005Date of Patent: September 26, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventor: George A. Andrews, Jr.

Patent number: 6955296Abstract: A gun control system is disclosed that includes a fire control kernel and location-independent software components within the fire control kernel. The kernel provides core fire control functionality that is unaffected by changes within the external environment, such as changes to the physical configuration of the gun system of which the gun control system is a part. Each location-independent software component has a specific functionality, and is able to run on any processor within the system in a location-independent manner. These software components can include a target/track management interface software component, a gun control system control interface software component, a gun mount control interface software component, an ownship data interface software component, and a gun control system display interface software component.Type: GrantFiled: June 26, 2003Date of Patent: October 18, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Paul W. Lusher, Henry T. Rowland

Patent number: 6834828Abstract: Actuators already present as an integral part of the control systems of missiles and the like are used to activate and control the deployment of fins and the like without the need for separate explosively or mechanically driven fin deployment systems. Springs located in hinges on the fins accomplish the complete deployment of the fins after proper orientation by the actuators.Type: GrantFiled: September 23, 2003Date of Patent: December 28, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventor: Benjamin R. Tritt

Patent number: 6817299Abstract: A fragmenting projectile includes a multi-wall projectile casing with each wall thereof formed by a sleeve. Each pair of adjacent sleeves is defined by inner and outer sleeves that mate in a threaded engagement. Explosive material is disposed in an innermost sleeve.Type: GrantFiled: December 10, 2003Date of Patent: November 16, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventor: David P. Cooke

Patent number: 6806423Abstract: A grounding device for water vehicles. The device includes an elongated electrical conductive section. The device also includes an elongated rope for increasing water resistance positioned in an adjacent relation to the elongated electrical conductive section. The device is of particular usefulness in grounding RF transmitters on high speed water vehicles having electrically insulative hulls.Type: GrantFiled: May 23, 2002Date of Patent: October 19, 2004Assignees: BAE SYSTEMS Information and Electronic Systems Integration Inc., The United States of America as represented by the Secretary of the NavyInventors: John Harris, David George Klingensmith, Sr., Marvin Bradford Hardy, Jr.
