Abstract: Aspects of the disclosure are directed to an engine oil damper comprising: a bearing support, and a housing radially outward from the bearing support and co-axial with the bearing support, where at least one oil flow restrictor is formed with respect to at least one of the bearing support and the housing, where the at least one oil flow restrictor is configured to at least partially interrupt a flow of oil in an annulus radially defined between the bearing support and the housing.

Abstract: A gas turbine engine includes a nacelle, a lower bifurcation structure, and a heat exchanger. The nacelle extends circumferentially around an engine core and defines a fan bypass duct that is substantially annular between an inner wall and an outer wall. The lower bifurcation structure extends between the inner wall and the outer wall, bifurcating the fan bypass duct. The lower bifurcation structure defines a bifurcation duct extending along a central axis of the lower bifurcation structure. A heat exchanger is positioned in the bifurcation duct.

Abstract: A core cowl for use with an engine core of a gas turbine engine includes a first cowl section for covering a first side of an engine core and a second cowl section for covering a second side of the engine core. A locking retractor connects the first cowl section to a support structure.

Abstract: A gas turbine engine includes an engine core, a core cowl extending circumferentially around the engine core, and a pressure actuated latch assembly. The core cowl includes a first cowl section on a first side of the engine core and a second cowl section on a second side of the engine core. The pressure actuated latch assembly connects the first cowl section to a support structure and is actuatable between an unlatched position when pressure within the core cowl is relatively low and a latched position when pressure within the core cowl is relatively high.
