INTERFACE BETWEEN A COMBUSTOR BASKET AND A TRANSITION OF A GAS TURBINE ENGINE

摘要

An interface (10) is provided between a combustor basket (12) and a transition (14) of a gas turbine engine (16). The interface (10) includes a tongue (18) formed in one of the combustor basket (12) and the transition (14), and a groove (20) formed in another of the combustor basket (12) and the transition (14). The tongue (18) is received within the groove (20) to define the interface (10). A sealing arrangement is also provided and includes an annular combustion outlet (12′″) and an annular transition inlet (14′″), with a labyrinth seal (72′″) positioned between an end (68′″) of the annular combustion outlet and an end (70′″) of the annular transition inlet to form a labyrinth path (34′″) there between. An inner diameter (24′″) of the annular combustion outlet (12′″) is axially aligned with an inner diameter (22′″) of the annular transition outlet (14′″).
