Abstract: An exhaust gas diffuser (38) including: a radially-outer peripheral casing (46); a hub (42) located within said radially-outer peripheral casing and coaxial with a center axis (40) of the casing; main struts (44) located at circumferentially-spaced locations about the hub and extending radially-outwardly to the radially outer peripheral casing; and small struts (52) located at circumferentially-spaced locations between the main struts; wherein the main struts and small struts have substantially parallel longitudinal chord lines and each of the small struts have a cross-sectional area smaller than a cross-sectional area of the main struts. An exhaust gas diffuser including: a radially-outer peripheral casing; a hub located within said radially-outer peripheral casing and coaxial with a center axis of the casing; main struts located at circumferentially-spaced locations about the hub and extending radially-outwardly to the radially outer peripheral casing; and small struts located at circumferentially-spaced locations between the main struts; wherein the main struts and small struts have substantially parallel longitudinal chord lines and each of the small struts have a cross-sectional area smaller than a cross-sectional area of the main struts.

Abstract: An exhaust gas diffuser for a turbomachine includes a diffuser supported on a turbine rotor, aligned with an axis of said turbine rotor. The diffuser is configured to re-direct turbine exhaust gas substantially ninety degrees from a first direction of flow along the rotor axis. A plenum chamber is in fluid communication with and surrounds an outlet end of the diffuser. The plenum chamber is in fluid communication with a transition duct adapted to supply the exhaust gas to another turbomachine. The plenum chamber expands in volume between the diffuser and the transition duct.
