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