Abstract
A separator for an annular gas turbine engine combustion chamber is disclosed having a plurality of separator segments arranged in a generally annular configuration to form an annular separator extending from an upstream end wall of a combustion chamber into the combustion chamber so as to separate first and second combustion zones within the combustion chamber. Each of the separator segments has a hollow interior defined by a front wall, an outer wall, an inner wall which has at least a portion tapering or converging towards the outer wall in a direction extending away from the front wall, and first and second sides. The sides define an array of holes communicating with the hollow interior, the positioning of the array of holes on a first sides being different from that of the array of holes on the second sides such that the axes of the holes are out of alignment with each other. The first sides of one separator segment is positioned adjacent to, but spaced apart from a second sides of an adjacent separator segment. Since the array of holes on the first sides is out of alignment with the array of holes on the second sides, pressurized gas within the interior of the hollow segment will pass through the holes in the first and second sides and will impinge upon the adjacent sides so as to cool both the adjacent sides and the sides through which the gas passes.
