摘要： A fan blisk, including a disk (12), a plurality of circumferentially spaced apart airfoils (16) extending radially outwardly from the disk (12), a plurality of shroud segments (18) being disposed circumferentially between the plurality of airfoils (16) and configured to attach to a corresponding airfoil of the plurality of airfoils (16) and a plurality of wear surfaces (22), where at least one wear surface of the plurality of wear surfaces (22) is configured and disposed to prevent excessive wear between the adjacent shroud segments (18). Each shroud segment of the plurality of shroud segments (18) may be attached to a corresponding airfoil (16) by weld connections (20) to permit clearance during translation friction welding of the airfoil (16) to the disk (12) hub are located to avoid high stress areas.
