Abstract
Provided is an airfoil insert for discharging an increased volume of cooling air. The insert comprises a perforated, tubular-shaped body with a first end for introducing the cooling air. A second end located opposite the first end and discharges an increased volume of the cooling air for use in cooling inboard components. The second end approximates a castellated wall and comprises one or more tabs spaced about the periphery. Alternating between tabs are notches in the body for discharging the cooling air. Covers may be joined to opposing tabs by bridging across the second end, or opposing tabs themselves may be joined together by bridging across the second end.
