Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 circumferentiall…
