Abstract

An air-cooled turbine component 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 (90) between and to an upstream end (120) of the internal cooling passage and a downstream end (122) of the internal cooling passage along a lengthwise axis (118) of the internal cooling passage. The body (90) 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 (136) arranged in a tread pattern along the inner passage wall (128).
