11. A turbine engine assembly comprising:
a static engine structure;
a fan section including a fan shaft coupled to a hub supporting a plurality of blades rotatable about an axis;
a fan drive gear system including a sun gear configured to be driven by an engine shaft rotatable about the axis, a plurality of intermediate gears intermeshed with the sun gear, a ring gear assembly engaged with the plurality of intermediate gears, the ring gear configured for attachment to the static engine structure, a carrier supporting rotation of the plurality of intermediate gears, the carrier is configured for rotation about the axis and includes a rotating oil inlet, and a rotating gutter attached to the carrier;
a transfer bearing fixed to the static engine structure and engaged to communicate oil to the rotating oil inlet;
a static baffle disposed radially outward of the transfer bearing and configured to capture oil expelled from the transfer bearing into the rotating gutter;
an aft auxiliary reservoir disposed radially outward of the rotating gutter;
an oil receiving surface configured to receive expelled oil from the rotating gutter and communicate the oil into the aft auxiliary reservoir;
the fan shaft coupled to the carrier;
a primary lubricant system communicating lubricant to the fan drive gear system; and
an auxiliary lubricant system including an auxiliary reservoir configured to receive lubricant expelled from the fan drive gear system and communicated through the aft auxiliary reservoir.
