An airfoil includes an airfoil section that has an airfoil wall that defines leading and trailing ends and first and second sides that join the leading and trailing ends. The first and second sides span in a longitudinal direction between first and second ends. The airfoil wall circumscribes an internal core cavity. A platform is attached with the first end of the airfoil wall. The platform includes an opening that opens into the internal core cavity and a land region that circumscribes the opening. A baffle is formed of a tube and an attachment portion. The tube extends in the internal core cavity and the attachment portion has a flange ring that is affixed to the platform at the land region.

A gas turbine engine article includes a baffle that is configured to be mounted in a cavity of a gas turbine engine component. The baffle has a baffle wall that circumscribes an open interior region. The baffle wall includes a forward wall, side walls, and an aft wall. The side walls include impingement orifices, and the aft wall defines two datum features. At least one of the datum features is a dimple that is a portion of a sphere.

Baffle with two datum features

A method of fabricating a baffle for a gas turbine engine component includes providing a baffle that has a baffle wall that circumscribes an open interior region, the baffle wall defining two datum features, wherein at least one of the two datum features is semi-spherical, establishing a fixed reference position of the baffle in a fixture by engaging the two datum features with two corresponding locators on the fixture, and performing at least one operation on the baffle that is dependent upon the reference position.

A baffle assembly includes a collar with a port and a baffle positioned in the port. The baffle includes two ends, a hollow body, and a weld connecting the baffle to the collar, and the collar continuously surrounds the body of the baffle.
