    Abstract: A gas turbine engine includes a core housing that has an inlet case and an intermediate case that respectively provide an inlet case flow path and an intermediate case flow path. The shaft supports a compressor section that is arranged axially between the inlet case flow path and the intermediate case flow path. The shaft includes a main shaft and a flex shaft having bellows. The flex shaft is secured to the main shaft at a first end and includes a second end opposite the first end. A geared architecture is coupled to the shaft, and a fan coupled to and rotationally driven by the geared architecture. The geared architecture includes a sun gear supported on the second end. A first bearing supports the shaft relative to the intermediate case and a second bearing supports the shaft relative to the inlet case. The second bearing is arranged radially outward from the flex shaft.

    Abstract: A variable vane system includes a first variable vane stage with a multiple of first actuator gears, each of the multiple of first actuator gears mounted to a respective variable vane of the first variable vane stage, and a second variable vane stage with a multiple of second stage actuator gears. Each of the multiple of second stage actuator gears mounted to a respective variable vane of the second variable vane stage, an extended geared unison ring driven by the drive gear, wherein the extended geared unison ring spans at least a first variable vane stage and a second variable vane stage, each of the multiple of first and second stage actuator gears driven by the extended geared unison ring.

    Abstract: One exemplary embodiment of this disclosure relates to a gas turbine engine. The engine includes a first rotor disk, a second rotor disk, and a circumferentially segmented seal. The segmented seal engages the first rotor disk and the second rotor disk. The segmented seal further includes a fore surface contacting the first disk, an aft surface contacting the second disk, and a radially outer surface. Further, (1) the aft surface and (2) one of the fore surface and the radially outer surface include perforations to allow fluid to flow through the interior of the segmented seal.
