20080236169 | COMBUSTOR FLOATING COLLAR WITH LOUVER - A gas turbine combuster ia provided with a dome heat shield having a fuel nozzle opening, the opening receiving a floating collar assembly for permitting relative movement between nozzle and heat shield. The floating collar is provided with a louver to provide film cooling to the face of the combustor heat shield and, thus, improve cooling thereof. | 10-02-2008 |
20090000303 | COMBUSTOR HEAT SHIELD WITH INTEGRATED LOUVER AND METHOD OF MANUFACTURING THE SAME - A combustor dome heat shield and a louver are separately metal injection molded and then fused together to form a one-piece combustor heat shield. | 01-01-2009 |
20090025224 | METHOD FOR MANUFACTURING OF FUEL NOZZLE FLOATING COLLAR - A floating collar is metal injected moulded with an excess portion intended to be separated, such as by shearing, from the reminder of the moulded floating collar to leave a chamfer thereon and/or remove injection marks. | 01-29-2009 |
20090211097 | METHOD FOR MANUFACTURING OF FUEL NOZZLE FLOATING COLLAR - A floating collar is metal injected moulded with an excess portion intended to be separated, such as by shearing, from the reminder of the moulded floating collar to leave a chamfer thereon and/or remove injection marks. | 08-27-2009 |
20090214375 | METHOD FOR MANUFACTURING OF FUEL NOZZLE FLOATING COLLAR - A floating collar is metal injected moulded with an excess portion intended to be separated, such as by shearing, from the reminder of the moulded floating collar to leave a chamfer thereon and/or remove injection marks. | 08-27-2009 |
20100050650 | GAS TURBINE ENGINE REVERSE-FLOW COMBUSTOR - A gas turbine engine reverse-flow sheet metal combustor for an aero gas turbine engine has a louverless single-piece liner design which includes a plurality of effusion patches, containing multiple rows of effusion cooling holes, bounded by cooled effusionless bands to aid in repairability of the combustor. The cooling of the bands improves the durability of the combustor and provides a method of repair for the combustor. | 03-04-2010 |
20110271528 | METHOD OF REPAIRING A GAS TURBINE ENGINE COMBUSTOR - A method of repairing an annular sheet metal combustor liner of a gas turbine engine includes cutting circumferentially around combustor liner bands bounding an effusion patch extending circumferentially around the liner, the effusion patch having effusion cooling holes and being bounded on either side by at least one effusionless band free from effusion cooling holes, to thereby remove a portion of the combustor liner having the effusion patch. A replacement liner portion including an effusion patch is provided and welded to the liner assembly, the weld extending circumferentially around the cut band to provide a welded effusionless band. The welded effusionless bands is cooled during engine use using one of film cooling of an inner surface of the welded effusionless band and impingement cooling of an outer surface of the welded effusionless band. | 11-10-2011 |
20130031909 | COMBUSTOR HEAT SHIELD WITH INTEGRATED LOUVER AND METHOD OF MANUFACTURING THE SAME - A combustor dome heat shield and a louver are separately metal injection molded and then fused together to form a one-piece combustor heat shield. | 02-07-2013 |
