    Abstract: An epicyclic gear assembly according to an exemplary aspect of the present disclosure includes, 60 among other things, a carrier including a first plate axially spaced from a second plate by a radially outer connector. A first set of epicyclic gears supported adjacent the first plate include a first set of circumferentially offset intermediate gears meshing with a first sun gear and a first ring gear. A second set of epicyclic gears are axially spaced from the first set of epicyclic gears and supported adjacent the second plate, and include a second set of circumferentially offset intermediate gears meshing with a second sun gear and a second ring gear. The first epicyclic gear set and the second epicyclic gear set maintain relative intermeshing alignment during flexure induced deformation of the carrier.

    Abstract: A gas turbine engine assembly includes, among other things, a clutch configured to move from a first position to a second position in response to rotation of a gas turbine engine fan at a speed greater than a threshold speed. Whether the clutch is in the first position or the second position, the clutch permits rotation of the gas turbine engine fan in a first direction. When the clutch is in the first position, the clutch limits rotation of the gas turbine engine fan only in an opposite, second direction. The clutch is disposed within a compartment that is accessible and removable via removal of an aft engine cover structure. The clutch is removable on-wing.

    Abstract: A gas turbine engine comprises a fan, a compressor section, a turbine section, and a gear reduction for driving the fan through the turbine section. A rotating element and at least one bearing compartment includes a bearing for supporting the rotating element, a seal for resisting leakage of lubricant outwardly of the bearing compartment, and for allowing pressurized air to flow from a chamber adjacent the seal into the bearing compartment. The seal has a plurality of sealing members extending radially toward a sealing surface.

    Abstract: A gas turbine engine includes a fan shaft arranged along an engine central axis, a frame supporting the fan shaft, a gear system rotatably coupled with the fan shaft, and a flexible coupling at least partially supporting the gear system. The flexible coupling defines, with respect to the engine central axis, a torsional stiffness TS and a lateral stiffness LS such that a ratio of TS/LS is greater than or equal to about 2.0 to reduce loads on the gear system from misalignment of the gear system with respect to the engine central axis.
