| 20090004013 | TURBINE BLADE NESTED SEAL AND DAMPER ASSEMBLY - A turbine blade damper-seal assembly includes a seal nested within a damper such that both the seal and damper are disposed to provide sealing between adjacent blade platforms. The seal traverses the seal slot in the damper and seals the gap between adjacent blade platforms for the full axial length of the neck cavity between adjacent blades. The damper is located in an aft most position and includes features to facilitate vibration-dampening performance. The damper also includes features that cause entrapment between blades and therefore avoids the conventionally required protrusions on the blade to retain it in the assembled position. | 01-01-2009 |
| 20090107237 | Shaft Trim Balancing Devices, Related Systems and Methods - Shaft trim balancing devices, related systems and methods are provided. In this regard, an representative device for trim balancing a rotatable shaft includes: an intermediate section being annularly shaped and having terminating ends spaced from each other in an uncompressed state of the device; and first and second sets of counterweights extending longitudinally from opposing sides of the intermediate section. | 04-30-2009 |
| 20100129194 | Castings, Casting Cores, and Methods - The pattern has a pattern material and a casting core combination. The pattern material has an airfoil. The casting core combination is at least partially embedded in the pattern material. The casting core combination comprises a metallic casting core and at least one additional casting core. The metallic casting core has opposite first and second faces. The metallic core and at least one additional casting core extend spanwise into the airfoil of the pattern material. In at least a portion of the pattern material outside the airfoil of the pattern material, the metallic casting core is bent transverse to the spanwise direction so as to at least partially surround an adjacent portion of the at least one additional casting core. | 05-27-2010 |
| 20100129195 | Castings, Casting Cores, and Methods - The pattern has a pattern material and a casting core combination. The pattern material has an airfoil. The casting core combination is at least partially embedded in the pattern material. The casting core combination comprises a plurality of metallic casting cores. Each metallic casting core has opposite first and second faces and a respective portion along the trailing edge of the airfoil. At least two of the metallic cores have sections offset between the pressure side and the suction side. | 05-27-2010 |
| 20120207616 | Castings, Casting Cores, and Methods - The pattern has a pattern material and a casting core combination. The pattern material has an airfoil. The casting core combination is at least partially embedded in the pattern material. The casting core combination comprises a metallic casting core and at least one additional casting core. The metallic casting core has opposite first and second faces. The metallic core and at least one additional casting core extend spanwise into the airfoil of the pattern material. In at least a portion of the pattern material outside the airfoil of the pattern material, the metallic casting core is bent transverse to the spanwise direction so as to at least partially surround an adjacent portion of the at least one additional casting core. | 08-16-2012 |

| 20100114838 | PRODUCT RELIABILITY TRACKING AND NOTIFICATION SYSTEM AND METHOD - Methods and apparatus are provided for tracking product reliability. A product removal database having removal data stored therein that are associated with one or more products is periodically accessed at a user-specified periodicity. An aircraft flight-hours database having time-in-flight data stored therein that are associated with each product is periodically accessed at the user-specified periodicity. One or more user-selected algorithms are executed, using at least a portion of the periodically accessed removal data, to determine if the criterion for a user-specified reliability parameter is met or not. If it is determined that the criterion for the user-selected reliability parameter is not met, then an alert is transmitted to a preset destination. | 05-06-2010 |
| 20100198635 | SYSTEM AND METHOD FOR PRODUCT DEPLOYMENT AND IN-SERVICE PRODUCT RISK SIMULATION - Methods and systems are provided for predicting the reliability of a plurality of products that will be deployed during a product deployment period comprising a plurality of time intervals. The method comprises retrieving historical product removal data from a product removal data source, retrieving historical product shipment data from a product shipment data source, identifying a plurality of Weibull parameters based on at least a portion of retrieved product removal data and product shipment data, and performing a plurality of product deployment simulations, wherein each product deployment simulation includes predicting a lifespan for each of the plurality of products and determining reliability metrics for uniform time intervals during the product deployment period. | 08-05-2010 |
| 20100318553 | PRODUCT FIX-EFFECTIVENESS TRACKING AND NOTIFICATION SYSTEM AND METHOD - Methods and apparatus are provided for tracking the effectiveness of a modification that has been installed into a product in response to an issued modification notice. A product removal database having removal data stored therein that are associated with one or more products is periodically accessed at a user-specified periodicity. One or more user-selected fix-effectiveness algorithms are executed to determine if at least a portion of the periodically accessed removal data matches one or more user-specified keywords that correlate to the modification. If it is determined that at least a portion of the periodically accessed removal data matches the one or more user-specified keywords, then an alert is transmitted to a preset destination. | 12-16-2010 |
