Abstract

An air-cooled turbine component (80) includes a body (90) extending between and to a first radial surface (112) and a second radial surface (114) relative to a centerline axis (74). The body (90) includes an outer passage wall (126) and an inner passage wall (128) forming an internal cooling passage (116) between the first radial surface (112) and the second radial surface (114). The internal cooling passage (116) extends lengthwise through the body between and to an upstream end (120) of the internal cooling passage (116) and a downstream end (122) of the internal cooling passage (116) along a lengthwise axis (118) of the internal cooling passage (116). The body forms a flow augmentation feature assembly (134) at the inner passage wall (128) within the internal cooling passage (116). The flow augmentation feature assembly (134) includes a plurality of trip strips (144) arranged in a lattice pattern (146) along the inner passage wall (128).Blade outer air seal (BOAS) segments are provided as the air-cooled turbine component.
