The engine includes a first turbine bearing defining an outer air bearing disposed radially adjacent to a low speed turbine rotor hub of a low speed turbine rotor and an inner bearing disposed radially adjacent to a high pressure (HP) shaft coupled to a high speed turbine rotor, wherein a first manifold is in fluid communication from a pressure plenum of a combustion section to the first turbine bearing, and wherein a second manifold is in fluid communication from the first turbine bearing to a pressure regulating valve and an outer diameter secondary flowpath of the turbine section, and wherein a third manifold is in fluid communication from the pressure plenum of the combustion section to the pressure regulating valve. The method includes flowing air from the pressure plenum to the first turbine bearing; flowing air between the outer air bearing and the low speed turbine rotor hub; flowing air between the inner air bearing and the HP shaft; flowing air from the first turbine bearing to the pressure regulating valve via the second manifold; and flowing air from the first turbine bearing to the outer diameter secondary flowpath via the second manifold.

Abstract: A thrust reverser system for incorporation into a nacelle assembly of a gas turbine engine includes a frame member and a forward ring movable along an axial centerline relative to the frame member. The forward ring is movable between a first position and the second position. The thrust reverser system additionally includes a cascade segment slidably attached to the frame member and rotatably attached to the forward ring. When the forward ring is in the first position the cascade segment is in a radially outer position, and when the forward ring is in the second position, the cascade segment is in a radially inner position for changing a direction of a flow of air to generate reverse thrust.

Abstract: A thrust reverser system and operation suitable for turbofan engines. Blocker doors of the thrust reverser system have stowed positions in which each door is disposed between a fixed structure and a translating cowl of the engine. The translating cowl is translated in an aft direction of the engine to define at least one opening with the fixed structure, after which the translating cowl is further translated aft to deploy linkage mechanisms that are received in slots recessed into the blocker doors and pivotably connect the doors to the fixed structure. Deployment of the linkage mechanisms from the slots causes the blocker doors to rotate to a deployed position in which each door extends across a bypass duct of the engine and diverts bypass air within the duct through the opening.
