Abstract: A wall is disclosed for a gas turbine engine combustion chamber having a generally annular configuration around a central axis wherein the wall has an inner surface bounding at least a portion of the combustion chamber and a plurality of rows of cooling openings, each cooling opening having an elongated, generally rectangular configuration with a length l and a width e such that l is greater than e, the cooling openings in each row being equidistantly spaced apart a distance d in which d is not greater than the length l. The cooling openings of a given row are circumferentially displaced from cooling openings of an adjacent row and, since the distance d is not greater than the length l of the cooling openings, the opening areas overlap in adjacent rows to provide an even distribution of the cooling film within the combustion chamber.
