Patent number: 8407862Abstract: A bi-directional releasable connector includes a connecting link defining a main tension leg and a pair of looped ends, the connecting link engaging a pair of spring-biased plungers axially movable independently of one another inside an outer housing. Axially outward movement of the plungers under the bias of the spring is limited by stops in the housing engaged by the plungers. Either end may be selectively opened and, in the static position with both ends closed, oppositely directed axial loads on the ends of the connector link are borne by the tension leg which is preferably made of steel or other high tensile strength material. Axial loads on the connector impose no loads or forces on the remaining components.Type: GrantFiled: August 2, 2010Date of Patent: April 2, 2013Assignee: The Worth CompanyInventor: Conrad Bluma

Patent number: 5954898Abstract: A method for fabricating a composite part (42) from a plurality of composite layers (14) is provided. The method includes laying-up the composite layers (26) one upon another to form a collection of layers in a configuration and debulking the configuration of layers (26) by applying pressure sufficient to reduce the thickness of the layers to within approximately twenty percent (20%) of the part's final thickness. The debulked layers (28) may then be stored, generally at room temperature. To later form the part, the debulked layers (28) are heated to a temperature above their glass transition temperature and formed into the part's final shape. Heat may then be continuously applied to the layers while holding them in the part's final shape with sufficient force to achieve and maintain the part's thickness and density and until the heating causes the layers to become sufficiently cured so that the part's shape, thickness, and density are maintained.Type: GrantFiled: October 2, 1997Date of Patent: September 21, 1999Assignee: Lockheed Fort Worth CompanyInventors: Elbert Lee McKague, James R. Albritton

Patent number: 5664415Abstract: An after-burning turbo-fan engine system (10) includes turbo-fan engine (14) for producing exhaust gas (20), and jet thrust therefrom. After-burning chamber (16) receives turbo-fan exhaust and injects a controllable amount of fuel into turbo-fan exhaust to cause after burning of the turbo-fan exhaust to produce after-burned exhaust (20). Nozzle (18) associates with after-burning chamber (16) for receiving after-burned exhaust (20). Nozzle (18) has a fixed geometry. Nozzle (18) flow coefficient control mechanism (22 and 24) controls the approach of after-burned exhaust (20) through nozzle (18) to change the nozzle (18) flow coefficient. This controls the volumetric flow rate of after-burned exhaust (20) through the nozzle (18).Type: GrantFiled: June 1, 1994Date of Patent: September 9, 1997Assignee: Lockheed Fort Worth CompanyInventor: Douglas A.

Patent number: 5645886Abstract: A system for sealing an exposed area of a surface coated with a radiofrequency signal absorbing coating includes a heat-responsive compound that transforms from a solid state to viscous melted state at temperatures above a predetermined temperature and that returns to a solid state after cooling to temperatures below the predetermined temperature. The heat-responsive compound has a radiofrequency absorbing material for absorbing radiofrequency signals at approximately equal frequency to those that the radiofrequency signal absorbing coating absorbs. An applicator applies the heat-responsive compound in the viscous melted state to cover the exposed areas. An absorptive tape conceals any gap or fastener associated with the exposed area and absorbs radiofrequency signals having approximately equal frequencies to those of the radiofrequency signal absorptive coatings.Type: GrantFiled: September 1, 1995Date of Patent: July 8, 1997Assignee: Lockheed Fort Worth CompanyInventors: John T. Schueler, II, Stanley L. Ramirez

Patent number: 5416411Abstract: A system is provided for measuring the thickness of a ferromagnetic layer formed over a conductive base layer. An eddy current probe is provided for measuring the thickness of the ferromagnetic layer. The eddy current probe can be placed in direct contact with the ferromagnetic layer, or it may be spaced above its surface by an unknown standoff distance. This spacing may be caused by the presence of an overlying nonferrous, nonconductive layer applied over the ferromagnetic layer, or it may be an air gap over the ferromagnetic layer. An analog detector connected to the probe provides output values in two dimensions corresponding to the modulation of the probe's magnetic field by the ferromagnetic and conductive layers. These values are utilized to determine a mapping between the detector output values and ferromagnetic layer thickness and standoff values. The output of the mapping function provides two values, a ferromagnetic layer thickness and a standoff distance, which corresponds to the detected values.Type: GrantFiled: January 8, 1993Date of Patent: May 16, 1995Assignee: Lockheed Fort Worth CompanyInventor: Dirk A. Elsmore

Patent number: 5406787Abstract: A method and apparatus are provided for generating thrust in a turbo-fan engine (10), including generating additional thrust with after-burning. Sensors are used for monitoring a temperature in nozzle (26) of engine (10) and fan stream pressure of engine (10). The measured temperature in nozzle (26) and pressure in the fan stream are compared to a predetermined schedule for temperature and pressure by controller (54). Based on the comparison, a portion of the fan stream will be modulated to fan stub stage (16) by variable bypass control (30). Variable bypass control (30) provides for variable compression within variable compression generator (12). The variable compression available from generator (12) is scheduled against the temperature rise and back pressure associated with after-burning so as to alleviate back pressure without having to increase the area of nozzle (26). This provides for a unique turbo-fan engine with after-burning capability but with a fixed geometry exhaust nozzle (26).Type: GrantFiled: August 20, 1993Date of Patent: April 18, 1995Assignee: Lockheed Corporation Lockeed Fort Worth CompanyInventor: Douglas A.
