Vane assembly and method of forming a vane assembly for a gas turbine engine

摘要

A method of working a vane assembly (10) for a gas turbine engine involves a collar (32) and an engine operated cooling baffle (14). The collar is connected to the cooling baffle and installed into the interior cavity (26) of the vane assembly. A braze is applied to both a portion (46) of the collar that interfaces with the cooling baffle and to a second portion (48) of the collar that interfaces with the vane assembly. In one embodiment, the connection between the replacement collar and both the cooling baffle and vane assembly is accomplished by fitting the cooling baffle into the collar and by slipping a portion of the cooling baffle with a smaller cross-sectional area through the collar, and both portions are brazed in the same operation.
