A turbine exhaust case for a gas turbine engine has an outer shroud and an inner shroud concentrically defining therebetween an annular gaspath for channelling hot gases. A plurality of circumferentially spaced-apart turbine exhaust struts extends radially across the hot gaspath. The inner shroud may be provided in the form of an acoustic panel. The acoustic panel has a radially outwardly facing surface defining the radially inner flow boundary surface of the gaspath. The acoustic panel is mechanically fastened to the radially inner end of the struts.


1. A turbine exhaust case disposed downstream of a last stage of turbine blades of a gas turbine for exhausting hot gases to the atmosphere, the engine having an axis, the exhaust case comprising a radially outer annular shroud and a radially inner annular shroud concentrically mounted about said axis and defining therebetween an annular gaspath for channeling hot gases received from the last stage of turbine blades of the engine, a plurality of circumferentially spaced-apart struts extending radially across the gaspath between the radially outer and the...
