WALL ELEMENTS FOR GAS TURBINE ENGINE COMBUSTORS

摘要

A wall element ( 29 ) for a wall structure ( 21 ) of a gas turbine engine combustor ( 15 ). The wall element ( 29 ) comprises a main member ( 36 ) with an upstream edge region ( 30 ) and a downstream edge region ( 31 ). A plurality of heat removal members ( 38 ) are provided on the main member ( 36 ). The downstream edge ( 35 ) of the wall element and/or the downstream facing surface of the heat removal members closest to the downstream edge ( 35 ) are provided with a thermally resistant coating.
