Part span shrouded fan blisk

An engine component comprising:

• a fan blisk, the fan blisk comprising:
• a disk body having a substantially circular geometry;
• a plurality of circumferentially spaced apart airfoils extending radially outwardly from the disk body, each airfoil being secured to the disk body;
• a plurality of shroud segments, each shroud segment being disposed circumferentially between the plurality of airfoils and configured to attach to a corresponding airfoil of the plurality of airfoils;
• wherein each shroud segment is attached to another shroud segment of the plurality of shroud segments by a weld connection on a predetermined location of the shroud segment, wherein each shroud segment of the plurality of shroud segments is a part span shroud segment, and;
• wherein the predetermined location of the weld connection is at a location between the disk and the end of the shroud segment, and wherein the weld connection is applied substantially perpendicular to the plurality of blade airfoils.

A method for manufacturing an engine component, the method comprising the steps of:

• manufacturing a fan blisk comprising the steps of:
• securing a plurality of blade airfoils to a disk;
• securing a plurality of shroud segments to the plurality of blade airfoils;
• and
• wherein the plurality of shroud segments are part span shroud segments that span at least a portion of the distance between adjacent blade airfoils, wherein the part span shroud segments extend substantially from a blade airfoil to an adjacent part span shroud segment, and wherein the part span shroud segments are attached with weld connections to adjacent part span shroud segments.
