Methods and apparatus for cooling gas turbine engine combustors

摘要

A one-piece deflector-flare cone assembly (75) for a gas turbine engine combustor that facilitates extending a useful life of the combustor in a cost-effective and reliable manner is described. The combustor includes an air swirler (90), and the one-piece assembly includes a deflector portion (76) and a flare cone portion (78). The deflector portion includes an integral opening (168) that extends circumferentially through the deflector portion for receiving cooling fluid therein. Because the deflector-flare cone assembly receives preloaded braze tape and braze rope, a single braze operation secures the deflector-flare cone assembly (75) within the combustor and to a combustor air swirler.
