A turbine assembly having an outer casing (), an inner structural ring (), and an annular gas path () defined between outer and inner flow path walls () for conducting a gas flow through the turbine assembly. A plurality of structural struts () are spaced apart in a circumferential direction, each strut () including a strut body () extending in a radial direction for supporting the inner structural ring () to the outer casing (). A first strut end () at a radially outer end of the strut body () is detachably attached to the outer casing () with a first fastener structure () engaging the outer casing (), and a second strut end () at a radially inner end of the strut body () is detachably attached to the inner structural ring () with a second fastener structure () engaging the inner structural ring ().

Turbine assembly with detachable struts

A turbine exhaust casing having an outer casing, an inner casing, an annular exhaust gas path defined between outer and inner flow path walls, and a turbine exhaust casing cavity located radially outward and radially inward from the gas path. A plurality of structural struts support the inner casing to the outer casing, and a fairing surrounds each of the struts in an area extending between the outer and inner flow path walls. A first purge air path extends through at least one of the struts for conducting purge cooling air radially inward to the inner casing, and a second purge air path extends through the strut for further conducting the purge cooling air radially outward to provide a flow of purge air to a location of the exhaust casing cavity radially outward from the outer flow path wall.
