Abstract: A gas turbine includes a compressor section and a turbine section extending along an axis; an outer casing and an inner casing, delimiting an annular cavity between one another in the turbine section; a cooling circuit, configured to direct cooling fluid flow from the compressor section to the annular cavity of the turbine section through cooling inlets in the outer casing; and baffles arranged in the annular cavity between respective cooling inlets and the inner casing and configured to intercept at least part of the cooling fluid flow when fed through the respective cooling inlets and to prevent intercepted cooling fluid flow from directly impinging on the inner casing.

Abstract: A fluid supply system for a rotary machine, the system includes a rotor assembly with an array of blades arranged to be driven about a primary axis to provide propulsive thrust in use, each blade having a longitudinal axis, the rotor assembly including a casing structure, wherein the casing structure is rotatable in unison with the blades about the primary axis; and a directional fluid intake, the intake being rotatably mounted at an outer surface of the casing structure about a second axis which is angularly offset from the primary axis and which is offset from and independent of the longitudinal axis of the blade.

Abstract: An engine casing element comprises at least one clearance control cavity, the clearance control cavity being delimited by a clearance control cavity inner wall and having a clearance control cavity longitudinal extent. At least one insert member is arranged inside the clearance control cavity. The insert member is arranged and configured to effect at least one of a flow guide function and a heat transfer enhancement function.
