Patent application number | Description | Published |
20090100838 | WALL ELEMENT FOR USE IN COMBUSTION APPARATUS - A tile for use as part of an inner wall of a gas turbine engine combustor, the tile being provided with deformable cooling pedestals extending into a space between the tile and the outer wall. The pedestals are deformed in contact with the outer wall of the combustor. | 04-23-2009 |
20090258168 | ARTICLE AND METHOD OF MANUFACTURE THEREOF - A particle damper is formed using a solid freeform manufacturing technique. A filler provides support for the closing wall of the cavity as it is formed. Apertures allow at least a portion of the filler to be removed. A particle fill of between 90 and 95% is achieved either by removing sufficient filler to reach this fill or removing excess filler and re-filling with damping particles. | 10-15-2009 |
20110030378 | COMBUSTOR TILE MOUNTING ARRANGEMENT - A tile is provided for lining the hot side of a wall of a combustor. The tile has a tile body with one or more bosses protruding from the cold side thereof. The or each boss extends, in use, through the wall of the combustor and has a threaded recess formed therein for threadingly connecting with a bolt which is inserted into the recess from the cold side of the combustor wall. The bolt fastens the tile to the combustor wall. | 02-10-2011 |
20110088408 | FUEL INJECTOR MOUNTING SYSTEM - A system for mounting a fuel injector to an engine casing with an aperture includes a fuel injector having a flange for mounting to the casing at the aperture. The flange allows it to pass through the aperture. An intermediate ring mediates the mounting of the flange to the casing at the aperture. The intermediate ring is inside the casing at the aperture and defines an opening from which the fuel injector extends into the engine with the flange positioned inward of the ring. The flange is dismountably sealed to an inner side of the ring, and the ring is dismountably sealed to an inner side of the casing to mount the fuel injector to the casing. On dismounting the flange from the ring, the fuel injector can be displaced to allow the ring, to be moved away from the aperture. The fuel injector can then be withdrawn. | 04-21-2011 |
20130199194 | COMBUSTOR HEAD ARRANGEMENT - A combustor head arrangement including a heatshield including an aperture therethrough. A meter panel having a cold side and a hot side, an aperture and a slot. At least one of the meter panel and the heatshield has a retaining feature on the cold side; one of the meter panel and the heatshield has an anti-rotation feature. The arrangement includes a burner seal sized to fit through the aperture in the meter panel from the hot side towards the cold side. The burner seal has a tang configured to pass through the slot when the burner seal is in a first orientation and to be retained by the retaining feature and the anti-rotation feature when the burner seal is rotated to a second orientation. Also a method of assembling the combustor head. | 08-08-2013 |
20130251941 | THERMAL BARRIER COATED ARTICLE AND A METHOD OF MANUFACTURING A THERMAL BARRIER COATED ARTICLE - A method of manufacturing a thermal barrier coated article including the steps of: a) forming an article having a first surface and a second surface, the article having a plurality of projections extending from the first surface in a direction away from the first surface and away from the second surface, each projection having a first end adjacent the first surface and a second end remote from the first surface, b) depositing a thermal barrier coating on the first surface of the article around each of the projections and on the second ends of the projections, c) removing the thermal barrier coating from the second ends of the projections, and d) forming at least one passage through each projection extending from the second surface of the article through the article and through the respective projection to the second end of the respective projection. | 09-26-2013 |
20140141174 | METHOD OF MANUFACTURING A THERMAL BARRIER COATED ARTICLE - A method of manufacturing a thermal barrier coated article including: forming an article having a first and second surface, the article having projections extending from the first surface away from the first and second surface, each projection having a first end adjacent the first surface and a second end remote from the first surface, each projection having a blind passage extending therethrough from the second surface through the article towards the second end of the projection, the blind passage in the projection being closed at the second end of the projection, depositing a thermal barrier coating on the first surface around each of the projections and on the second ends, removing the thermal barrier coating from the second ends, and removing the second end of each projection to form a passage through the projection extending from the second surface through the article to the second end of the projection. | 05-22-2014 |
