摘要： A high temperature repairable airfoil (30) having a plurality of flow path cover tiles (45a-d) coupled to a single crystal spar member (44). In one embodiment, the plurality of flow path cover tiles (45a-d) include an attachment portion (47) that is received within a groove (46) formed in the outer surface of the spar. The attachment portion (47) slides into a retaining feature (49) within the groove (46) so as to limit movement of the plurality of flow path cover tiles (45). Upon rotation of the airfoil (30), the plurality of flow path cover tiles (45) become centrifugally loaded with a portion of the spar member (44). In one embodiment, the plurality of flow path cover tiles (45a) are formed of a material selected from the group consisting of ceramics, intermetallic, and thermal barrier coated single crystal alloy material.

摘要： An actively cooled component (24) having a plurality of film cooling discharge apertures (50) passing through a heat transfer pedestal (55). In one embodiment the pedestal (55) is elongated so as to provide good covered turning for the cooling media exiting the cooled component. In one embodiment the discharge aperture has an L/D ratio in the range of about two to three.
