Each burner (4) is arranged in a through-opening (5) provided on the housing (3), and substantially sleeve-shaped adapter devices (6) which receive and align the burners (4) are provided in the through-openings (5), said adapter devices projecting into the annular combustion chamber (2) and having a shielding plate (9) that extends radially to the burner axes (8) at the annular combustion chamber-side ends (7) of the adapter devices. The shielding plate is provided with through-holes (10) which are formed concentrically to the through-openings (5), and the adapter devices (6) are arranged on a ring between an approximately cylindrical outer shell (11) of the annular combustion chamber (2) and an approximately cylindrical hub-side wall (12) such that a cavity (13) is formed between the adapter devices (6) and the outer shell (11) or the hub-side wall (12) and between the housing (3) and the shielding plate (9). The shielding plate (9) has resonator openings (14), and partitions (15) are arranged in the cavity (13). The invention further relates to a gas turbine (17).

摘要： A gas turbine engine augmentor includes an inter-liner cavity (84) including an axially extending annular gap (62) separating augmentor and tailpipe liners (116, 118). A purge flow cavity (226) is in fluid communication with a fan bypass duct and with the cavity (84). An ejector (239) in fluid communication with the bypass duct includes an ejector nozzle (241) positioned and aimed to direct an ejector nozzle flow (256) from inside the ejector nozzle (241) across the cavity (84). The purge flow cavity (226) may be bifurcated into forward and aft purge flow cavities (230, 232) which are in fluid communication with the ejector (239) and inter-liner cavity (84) respectively. An annular dividing wall (245) having ejector metering apertures (242) may be disposed between the forward purge flow cavity (230) and an ejector plenum (244) of the ejector (239). An annular trapped vortex cavity pilot may be located upstream of the annular gap (62). The aft purge flow cavity (232) may be outwardly bounded by a seal (258) having purge metering apertures (259) disposed therethrough.

摘要： A ducting arrangement (10) in a combustion stage downstream of a main combustion stage of a gas turbine engine is provided. A duct (18) is fluidly coupled to receive a cross-flow of combustion gases from the main combustion stage. Duct (18) includes a duct segment (23) with an expanding cross-sectional area (24) where one or more injector assemblies (26) are disposed. Injector assembly (26) includes one or more reactant-guiding structures (27) arranged to deliver a flow of reactants into the downstream combustion stage to be mixed with the cross-flow of combustion gases. Disclosed injector assemblies are arranged in expanding cross-sectional area (24) to reduce total pressure loss while providing an effective level of mixing of the injected reactants with the passing cross-flow. Respective duct components or the entire ducting arrangement may be formed as a unitized structure, such as a single piece using a rapid manufacturing technology, such as 3D Printing/Additive Manufacturing (AM) technologies.
