A combustion liner for a gas turbine engine

摘要

A combustion duct assembly (45) has a transition duct (52) and a combustion liner (48) having a hula seal (50) at a downstream end that is forced within an inner wall (55) of the transition duct (52). The combustion liner (48) is held within the transition duct (52) by the hula seal (50), but allowed to move relative to the transition duct (52). The combustion liner (48) is formed with heat transfer columns (60) adjacent the downstream end, and radially inwardly of the hula seal (50).
