Abstract
An impingement insert for HGP component may include a hollow body having a longitudinal extent, an exterior surface and an interior surface. The hollow body may include a first side wall, a second side wall contiguous with the first side wall at a first end of each, the second side wall is flexibly movable relative to the first side wall. A spring element is contiguous with a second end of each of the first side wall and the second side wall, and extends along at least a portion of the longitudinal extent of the hollow body and into the hollow body between the first side wall and the second side wall. The spring element biases the side walls to an expanded position from a compressed position of the hollow body. Cooling passages pass between the exterior surface and the interior surface of the hollow body in both side walls.
