    Abstract: A gas turbine engine includes a fan section, a compressor section aft of the fan section, a combustor fluidly connected to the compressor section, and a turbine section fluidly connected to the combustor. The turbine section includes at least a first turbine and a second turbine. The second turbine operates at a higher pressure than the first turbine. A shaft is connected to the first turbine section such that the first turbine section is operable to drive rotation of the shaft. The shaft is a rotational input for a split gear and the split gear is connected to the fan and at least one of the multiple compressors.

    Abstract: A gas turbine engine includes a fan section and a speed change mechanism for driving the fan section. The speed change mechanism is an epicyclic gear train. A torque frame surrounds the speed change mechanism and includes a plurality of fingers. A bearing support is attached to the plurality of fingers. A first fan section support bearing is mounted forward of the speed change mechanism and a second fan section bearing is mounted on the bearing support aft of the speed change mechanism. The second fan section bearing is a fan thrust bearing.

    Abstract: A heat exchanger includes a heat exchanger body having a plurality of stacked panels defining an internal manifold and an external manifold. Each of the stacked panels includes an internal structure partially defining an internal manifold, an external structure partially defining the external manifold, and a plurality of ribs connecting the internal structure to the external structure. Each of the ribs further comprises a channel protruding into the rib and being paired with a corresponding rib of an adjacent panel, such that each of the ribs and the corresponding rib defining a cooling passage fluidly connecting the internal manifold to the external manifold. Each of the stacked panels is bonded to at least one adjacent stacked panel.
