Abstract
A wall element of a gas turbine engine having an inner hot surface, and an outer cooler surface, during use. A plurality of projections is provided on the outer surface to facilitate heat transfer to a coolant flow during use. The projections are arranged in a first density pattern and in a second higher density pattern for increased cooling. The second higher density pattern is positioned adjacent a hotter region of the tile than the first density pattern to reduce the thermal gradient throughout the wall element.
