ABSTRACT:
The expense of a cover (80) for non-uniform structure (38) on or adjacent a surface (90) of a rear turbine shroud 34 facing a cooling passage defined by the rear engine shroud (34) and a wall (62) of a combustor (50) in a gas turbine engine can be avoided by providing a connecting wall (100) that is smoothly curved between the radially inner wall (58) and a conical wall (62) of the combustor (50). The resulting cooling air stream will attach itself to the walls (100) and (62) by reason of the Coanda effect, rendering the presence of non-uniform structure (38) on the surface (90) unimportant.
