A turbine exhaust case comprises inner and outer annular shrouds defining therebetween an annular hot gaspath. A circumferential array of exhaust struts extends across the gaspath. The exhaust struts are mounted at one radial end thereof on a flexible strut mounting structure. The flexible strut mounting structure is radially deflectable relative to the outer and inner shrouds to accommodate thermal expansion of the exhaust struts during engine operation.


1. A turbine exhaust case for a gas turbine engine having an axis, the turbine 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 channelling hot gases; at least one strut support ring mounted inside said annular gaspath adjacent to and spaced apart from an associated one of said radially outer annular shroud and said radially inner annular shroud so as to define a radial gap with the associated one of said radially outer annul...
