ABSTRACT:
A transition assembly for directing the gas flow from a combustor to an axial turbine includes a transition liner having a shroud disposed about its outer surface and abutting thereto at a plurality of points to defining a plurality of cooling air passages therebetween. The downstream end of the assembly is circumscribed by the first stage stator and extends axially to just upstream of the first stage turbine rotor. At this end a plurality of circumferentially spaced struts are mounted between the liner and the shroud to define a plurality of axially facing nozzles which are angled to impart a pre-swirl to the cooling air exiting therefrom.
