20090000101 | Methods for Repairing Gas Turbine Engines - Methods for repairing gas turbines are provided. A representative method includes: identifying an affected area of a surface of a component of the gas turbine, the surface of the component defining a portion of a gas flow path through the gas turbine; applying an epoxy-based filler to the affected area; curing the epoxy-based filler; and blending the epoxy-based filler with the surface of the component. | 01-01-2009 |
20090064500 | METHOD OF REPAIRING A TURBINE ENGINE COMPONENT - The inventive method involves the inspection of a turbine engine. A damaged component of the turbine engine is identified. Portions of the turbine engine component are removed from the damaged area to accommodate an overlay. The overlay is sized smaller than the turbine engine component. The overlay is then placed in a location previously occupied by the removed portion and attached to the turbine engine component. | 03-12-2009 |
20090136740 | ARTICLE HAVING COMPOSITE LAYER - A composite article includes a substrate and a layer attached to the substrate. The layer includes a metal phase, a first ceramic phase, and a second ceramic phase. | 05-28-2009 |
20090286003 | METHOD OF COATING A TURBINE ENGINE COMPONENT USING A LIGHT CURABLE MASK - A method of coating a turbine engine component involves providing the turbine engine component with a first area and a second area. The first area neighbors the second area. A cover is disposed over the first area of the turbine engine component. The second area of the turbine engine component is coated with a first coating curable from exposure to a light. The second area of the turbine engine component is exposed to light resulting in the curing of the first coating. The cover is removed from the first area. The first area of the turbine engine component is then sprayed with a second coating different from the first coating. | 11-19-2009 |
20100021716 | THERMAL BARRIER SYSTEM AND BONDING METHOD - A composite article includes a substrate, a ceramic member on the substrate and a ceramic bond coat for securing the substrate and the ceramic member together. A method of securing the ceramic member and the substrate together includes pyrolyzing a ceramic precursor, such as a ceramic powder, between the substrate and the ceramic member to form the ceramic bond coat. | 01-28-2010 |
20110027573 | Lubricated Abradable Coating - A coated article has a metallic substrate. A coating layer comprises at least 33% by volume ceramic, at least 5% by volume of a lubricant selected from the group consisting of hexagonal boron nitride (hBN), clay, graphite, and mixtures thereof. The coating layer lacks a metal phase of more than 5% by volume. | 02-03-2011 |
20110110783 | Trunnion hole repair utilizing interference fit inserts - A vane shroud for a gas turbine engine has a cylindrical shaped body and a hole arranged at a circumference of the body. The hole is for receiving a trunnion from a variable vane. A counterbore is arranged concentrically around the hole on a radially inward facing surface of the body, and receives a trunnion hub from the variable vane. A shrink-fit insert is seated into the counterbore such that the trunnion hub is provided with a contact surface, and the shrink-fit insert is secured to the shroud through an interference fit. | 05-12-2011 |
20110256321 | ARTICLE HAVING COMPOSITE LAYER - A composite article includes a substrate and a layer attached to the substrate. The layer includes a metal phase, a first ceramic phase, and a second ceramic phase. | 10-20-2011 |
20120082790 | ULTRAVIOLET ANGLED SPRAY NOZZLE - An apparatus for masking an article with masking material is disclosed. The apparatus generally includes a spray head connected to a primary channel which forms a passage for the masking material. This channel has two sections, the first of which terminates in a junction with the spray head and is angled from the second section. In addition, the apparatus has at least one secondary channel which forms an air passage and is attached to the primary angled channel | 04-05-2012 |
20120125011 | METHOD FOR USE WITH ANNULAR GAS TURBINE ENGINE COMPONENT - A method is provided for use with an annular gas turbine engine component that includes a main body and an annular seal engaged to the main body with an interference fit. The method includes rotating the annular gas turbine engine component, directing thermal energy from a heat source at the annular seal to thermally expand the annular seal relative to the main body while the annular gas turbine engine component rotates, removing the heated annular seal from the main body, providing a newly manufactured replacement detail having substantially the same configuration as the main body, and engaging the removed annular seal to the replacement detail with an interference fit. | 05-24-2012 |
20130071235 | LIGHT WEIGHT ABRADABLE AIR SEAL - An air seal for use with rotating parts includes an abradable layer adhered to a substrate. The abradable layer comprises a matrix of agglomerated hexagonal boron nitride and an oxide ceramic. Another hexagonal boron nitride is interspersed with the matrix. | 03-21-2013 |
20130186920 | FEED RATE CONTROLLER FOR GRANULATED MATERIALS - The flow of granulated materials from a supply hopper to a transport tube is controlled. A material feed friction tube is positioned to receive material from the hopper. The friction tube receives material independent from hopper pressure and the material moves to an orifice. The orifice discharges material to a pickup tube from the orifice and includes a transfer tube for receiving material from the pickup tube. The pickup tube has a source of carrier gas sufficient to move the material into the transfer tube for further use. | 07-25-2013 |
