Following the correct sizing of the skin and joining to the flange the attachment features are removed along with the assigned scrap portion of the skin. | 03-04-2010 |
20120247123 | SECURING SYSTEM - A securing system is provided for securing a component to a gas turbine engine casing. The system has a core engine casing formed from a front casing portion and a rear casing portion. The casing portions have respective casing flanges at which the casing portions are detachably joined together. The system further has a component flange extending from a component. The component flange is configured so that, when the casing portions are joined together, the component flange is trapped between the casing flanges. One of the casing flanges projects inwards from the casing to form an airtight seal with the component flange on the inside of the casing. The other of the casing flanges projects outwards from the casing to form an airtight seal with the component flange on the outside of the casing. | 10-04-2012 |
20120272652 | HEAD PART OF AN ANNULAR COMBUSTION CHAMBER - A head part of an annular gas turbine combustion chamber including: an end wall with a passage opening for accommodating a burner, the end wall including a set back portion adjacent the passage opening; a heat shield covering a back side of the end wall which faces towards the combustion chamber, the heat shield including a protruding portion shaped to cooperate with the set back portion of the end wall; and a burner collar adapted to fit within the passage opening and receive a burner, the burner collar including a protruding portion radially protruding from an outer surface of the burner collar; wherein the head part of the annular gas turbine combustion chamber is configured such that in an installed configuration the protruding portion of the burner collar is held between the protruding portion of the heat shield and the set back portion of the end wall. | 11-01-2012 |
20130031904 | COMBUSTION CHAMBER - A combustion chamber includes at least one annular wall. The annular wall includes a plurality of segments and each segment has a first portion, a second portion and a third portion. The first portion of each segment extends circumferentially, the third portion of each segment extends circumferentially and the second portion of each segment extends radially to connect the first portion and third portion of the segment. The segments are arranged such that the first portion of each segment overlaps the third portion of an adjacent segment and the first portion of each segment is bolted to the third portion of the adjacent segment. The segments are cast and define a double wall combustion chamber and enable easier construction of the combustion chamber and replacement of damaged segments. | 02-07-2013 |
