Title: Insert system for an airfoil and method of installing same

Abstract

An insert system for an airfoil is provided. The airfoil includes a plenum that extends into an aft portion of the airfoil. The plenum includes a plenum inlet and an entirety of the plenum inlet is defined axially forward of the aft portion. The insert system includes a first and second insert. The first insert and the second insert include a plurality of impingement openings defined therein. The first insert includes a first neck portion. The first insert is sized for insertion into the plenum radially through the plenum inlet and the first insert is movable aftward within the plenum into an installed position such that the first neck portion is positioned aftward in the plenum inlet. The second insert is sized for insertion into the plenum radially through the plenum inlet forward of the first neck portion in the installed position.
