Abstract: A vane assembly for a gas turbine engine which is a single unitary component that includes an aerofoil. A leading edge passageway is disposed proximal to a leading edge of the aerofoil and configured to receive a flow of a fluid therein. The vane assembly further includes a connecting passageway fluidly communicating the leading edge passageway with a trailing edge distribution passageway that is spaced apart from the leading edge, the leading edge passageway and a trailing edge of the aerofoil. The vane assembly further includes a plurality of trailing edge passageways disposed proximal to a pressure surface of the aerofoil and extending from the trailing edge distribution passageway towards the trailing edge along a chordwise direction. Each trailing edge passageway is configured to discharge the fluid through a corresponding passageway outlet disposed on the pressure surface and in fluid communication with a corresponding trailing edge passageway.

Abstract: A bearing support structure for a gas turbine engine located within an internal portion of the engine. The bearing support structure has a plurality of stators, a first section, a second section, a first bearing assembly, and a second bearing assembly. The first section depends forwardly from the plurality of stators relative to the longitudinal axis. The section second depends rearwardly from the plurality of stators relative to the longitudinal axis and is detachably mounted to the plurality of stators. The first bearing assembly is supported relative to the plurality of stators by the first section. The second bearing assembly is supported relative to the plurality of stators by the second section. The second section is detachably mounted to the plurality of stators.
