| 20110229305 | COVER PLATE FOR TURBINE VANE ASSEMBLY - Embodiments of a cover plate and material blank for forming the cover plate may include features and characteristics to accommodate tolerance issues in a turbine vane assembly. In one embodiment, the cover plate is formed from a material blank configured to provide the cover plate with a flexible flange area that can be secured to the turbine vane assembly. The flange area may have a range of motion that may be responsive to an installation force, which effectively modifies the configuration of the cover plate to such degree as to seal the cover plate to the turbine vane assembly. | 09-22-2011 |
| 20100030365 | COMBINED MATCHING AND INSPECTION PROCESS IN MACHINING OF FAN CASE RUB STRIPS - A workpiece is secured to a rotatable spindle with locking mechanisms and an image recording device takes an image of the workpiece secured to the spindle. The recorded image is compared to a database to select the appropriate program for the workpiece. A cutting tool is provided, and a rough material removal process is initiated on the workpiece. The surface of the workpiece where material has been removed is then inspected. | 02-04-2010 |
| 20090254286 | Systems and Methods for Modeling Surface Properties of a Mechanical Component - There is a method for modeling the surface fatigue life of a mechanical component. The method has the following steps: a) modeling the surface fatigue life of the mechanical component on an atomistic scale to form an atomistic model, b) modeling the surface fatigue life of the mechanical component on a mesoscale to form a mesoscale model, c) modeling the surface fatigue life of the mechanical component on a macroscale to form a macroscale model, and d) testing the surface fatigue life of the mechanical component. Feedback from the macroscale model is employed at least once to validate the atomistic model. Feedback from the macroscale model is employed at least once to validate the mesoscale model. Feedback from the testing is employed at least once to validate the macroscale model. There is also an interactive, multiscale model for prediction surface fatigue life or degradation rate for a mechanical component. | 10-08-2009 |
