Turbine engine components are provided for use with a plurality of blades (148), where each blade has an attachment portion (158) defined by a wall (160) and a surface (162). The components include a disk (146) having a first side (150), a second side (152), and an outer radial section (153) with a rim (154) and an overhang (155). Disk slots (156) extend radially inwardly from the disk rim (154), and each is configured to receive the attachment portion (158) of a corresponding blade such that when the blade (148) is disposed therein, the wall (160) of the blade attachment portion (158) is substantially flush with an adjacent portion of the first side (150) of the disk (146) and each disk slot (156) defines a cooling air passage (166) with the surface (162) of the blade attachment portion (158), where the cooling air passage (166) extends axially from the disk first side (150) to the disk second side (152). A cooling air slot (174) is formed in the disk first side (150) and extends radially outward from the overhang (155) of the disk (146) to the cooling air passage (166).
