COMBUSTOR ASSEMBLY

A combustor assembly (100) for a gas turbine engine includes a combustor dome (102) having a hot side (152) and a cold side (150) and at least in part defining a combustion chamber (108). The combustor assembly (100) additionally includes a fuel-air injector hardware assembly (146) having a first member (156) and a second member (158). The first member (156) is positioned at least partially adjacent to the cold side (150) of the combustor dome (102) and the second member (158) is positioned at least partially adjacent to the hot side (152) of the combustor dome (102). The first and second members (156, 158) together define an attachment interface (168) joining the first member (156) to the second member (158) and mounting the fuel-air injector hardware assembly (146) to the combustor dome (102). The attachment interface (168) may be shielded from the combustion chamber (108) to protect the attachment interface (168) from an undesirable amount of thermal expansion and to maintain the materials within desired material operating temperature limits.
