ABSTRACT:
The impingement baffle insert of a turbomachinery blade is provided with a plurality of collars around a portion thereof so as to ensure a proper impingement distance between the baffle and the inside wall of the airfoil and act as a wear surface against the inside wall to thereby prevent wear to the insert wall surface. The collars are affixed to the insert in preselected positions and frictionally engage the blade inner wall in close fit relationship to position the inserts and assume any wear that may result from vibration of the insert within the chamber. The inserts may have grooves formed therein to allow equalization of pressure on both sides thereof, and they may further have chamfered edges on one end thereof so as to facilitate installation into the turbine blades.
