Abstract: A gas turbine engine includes an engine core and core nacelle cowling coupled to the engine core. The engine core has a core member that extends radially outward from the engine core. The core nacelle cowling has a cowling member that extends radially inward towards the engine core. The cowling member is offset axially from the core member to form a labyrinth seal that bounds a coolant inlet, thereby fluidly coupling the fan duct flow of the gas turbine engine with a core compartment defined between the engine core and core nacelle cowling.
Abstract translation: 燃气涡轮发动机包括联接到发动机芯的发动机芯和核心机罩罩。 发动机芯具有从发动机芯径向向外延伸的芯构件。 核心机罩罩具有朝向发动机芯径向向内延伸的整流罩构件。 整流罩构件与芯构件轴向偏移以形成界定冷却剂入口的迷宫式密封件，从而将燃气涡轮发动机的风扇管道流动与限定在发动机核心和核心机舱罩之间的核心隔室流体耦合。

Abstract: A gas turbine engine includes a turbine and a compressor in rotational communication with the turbine via a shaft. The shaft is rotatable about a longitudinal centerline and includes a first axial end and a second axial end opposite the first axial end. The gas turbine engine further includes a first bearing compartment including a first compartment casing detachably mounted axially outside the compressor and the turbine. The first bearing compartment is in contact with the first axial end of the shaft and includes a first bearing which rotatably supports the shaft. The first bearing compartment is self-contained such that an internal lubrication system of the first bearing compartment is fluidally isolated from a remainder of the gas turbine engine outside the first bearing compartment.

Abstract: A geared turbofan engine is provided that includes a first rotor, a second rotor and a gear train that are arranged along an axis within a casing. The first rotor is connected to and driven by the second rotor through the gear train. The casing includes a nozzle, a bifurcation, a thrust reverser and a flowpath. The flowpath extends axially to the nozzle and circumferentially between opposing surfaces of the bifurcation.
