Method of fabricating a nearwall nozzle impingement cooled component for an internal combustion engine

A method of forming an internal combustion engine hot gas path component comprising a multi-panel outer wall, the multi-panel outer wall comprising an inner panel comprising an inner surface that defines at least a portion of a hot gas path plenum and an outer surface, the inner panel outer surface comprising discrete pockets formed by integral structural ribs, each pocket comprising a film cooling hole permitting fluid communication between the pocket and the plenum, the method comprising:

• forming dimples in an intermediate panel, at least one dimple comprising a nozzle;
• securing the intermediate panel to the inner panel outer surface, thereby enclosing at least one pocket;
• ensuring a respective dimple comprising a nozzle protrudes into a respective enclosed pocket and a respective nozzle is configured to direct a respective jet of cooling fluid onto a portion of the inner panel outer surface within the respective enclosed pocket;
• and
• ensuring an outer tip of the ribs contacts the intermediate panel in a part of the intermediate panel free of the dimples.
