Patent

CA 2383463

A one-piece deflector-flare cone assembly (75) for a gas turbine engine combustor (16) that facilitates extending a useful life of the combustor in a cost- effective and reliable manner is described. 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 through the deflector portion for receiving cooling fluid therein. The cooling opening extends circumferentially within the deflector portion. Cooling fluid discharged from the cooling opening is used for impingement cooling a portion of the flare cone portion to facilitate reducing an operating temperature and extending a useful life of the combustor.
