Abstract

1459500 Gas turbine combustion chambers GENERAL ELECTRIC CO 7 Feb 1974 [12 Feb 1973] 05734/74 Heading F1L To ensure the promotion of an even film of cooling air over the inner surface 62 of the liner 34 of a gas turbine combustion chamber, the liner is formed with circumferential ridges 64 defining chambers 72 in which air from inlets 76 diffuses to provide uniform, velocity distribution prior to exiting through outlets 68 to flow along walls 62 the downstream lip 74 at the exit changing the direction of flow from the chamber interior. As shown, the chamber 72 is inclined to the combustion chamber axis, and the air inlets 76 directed upstream towards an opposed wall 77. Again, the ridges 64 may be of rectangular section, Fig. 5 (not shown) and the air inlets may be formed in wall 77 directed downstream towards walls 76, Fig. 6 (not shown). Again, Figs. 7 and 8 (not shown) the chambers may be parallel to the combustion chamber axis, but radially offset outwardly from the liner walls. The air inlets (84) are formed in the upstream end-wall of the chambers and directed against the opposed endwall under an overhanging lip (102).
