ABSTRACT:
A gas turbine engine power turbine support structural nozzle includes a nozzle ring with an annular outer shroud and an inboard blade platform having a plurality of cast nozzle vanes therebetween located at circumferentially spaced points for directing motive fluids through the turbine; the support includes bearing oil and air coolant annuli. The outer annular engine case has mounting holes therein that receive a plurality of circumferentially spaced radially directed mounting trunnions through which both oil and coolant are supplied from external of the case to the annuli and the trunnions are coupled to the outer case by means that accurately cross key locate the nozzle ring within the engine case for free radial expansion relative thereto and wherein an annular index flange of the nozzle platform slidably supports a bearing cage engaged by dowel pins to accurately cross key locate and thermally accommodate the bearing cage with respect to the nozzle ring to maintain it accurately centered with respect to the turbine case during thermal excursions of the nozzle ring with respect thereto.
