ABSTRACT:
A gas turbine engine annular combustor (16) has a bulkhead (19) at its upstream end which is protected by an annular array of heatshields (32). Each of the heatshields (32) is spaced apart from the bulkhead (19) by flanges (37, 38,39,40) on the upstream heatshield face. Cooling air entry apertures (47) provided in the bulkhead (19) direct cooling air into the space (36) between the bulkhead (19) and each heatshield (32). The flanges (37,38,39,40) direct the cooling air so that some flows towards a fuel burner aperture (35) in the center of each heatshield (32) while the remainder flows towards the heatshield (32) edges.
