IMPINGEMENT INSERT FOR A HOT GAS PATH COMPONENT AND CORRESPONDING HOT GAS PATH COMPONENT

摘要

An impingement insert (180) for HGP component (122) may include a hollow body (190) having a longitudinal extent, an exterior surface (192) and an interior surface (184, 194). The hollow body (190) may include a first side wall (200), a second side wall (202) contiguous with the first side wall (200) at a first end (204, 232) of each, the second side wall (202) is flexibly movable relative to the first side wall (200). A spring element (210) is contiguous with a second end (212, 252) of each of the first side wall (200) and the second side wall (202), and extends along at least a portion of the longitudinal extent of the hollow body (190) and into the hollow body (190) between the first side wall (200) and the second side wall (202). The spring element (210) biases the side walls (200, 202) to an expanded position from a compressed position of the hollow body (190). Cooling passages (220) pass between the exterior surface (192) and the interior surface (184, 194) of the hollow body (190) in both side walls (200, 202).
