    摘要: An assembly, for example in a gas turbine engine, comprises a rotatable component 24, 26 supported by a bearing 30 in a support structure 16. A sealing arrangement 38 comprises a non-rotating sealing ring 56 which makes sealing contact with sealing features 60 on the rotatable component 24, 26. The non-rotating sealing ring 56 is radially displaceable with respect to the support structure 16 by means of ribs 62, 64 which engage axially facing support faces 66, 68 of the support structure 16. The non-rotating sealing ring 56 is radially located by an outer, non-rotating, race 44 of the bearing 30, by means of a locating surface 76 on a locating body 74 of the non-rotating sealing ring 56.
    As a result of this arrangement, the running clearance at the sealing arrangement 38 can be maintained, despite radial displacement of the rotatable component 24, 26 with respect to the support structure 16, and despite thermal and mechanical deflections of the support structure 16.

    摘要: A duct wall (2) of a fan casing of a gas turbine engine comprises an intake section (4) and a containment casing (6), provided respectively with flanges (20,22). An acoustic flutter damper (28) is secured between the flanges (20,22). The acoustic flutter damper (28) has a skin (34,36) which accommodates an internal structure which serves to provide damping of flutter arising in fan blades (18). In the event of detachment of a blade (18) or a blade fragment, the resulting deflection wave in the containment case (6) causes the internal structure to rupture, and the load path between the intake section (4) and the containment casing (6) passes along the skin (34,36), which consequently maintains the connection between the intake duct (4) and the containment casing (6), while permitting substantial radial deflection of the containment casing (6) relative to the intake section (4).

    摘要: A duct wall 2 of a fan casing of a gas turbine engine comprises an intake section 4 and a containment casing 6, which are interconnected by bolts 50 at flanges 20, 22. An acoustic flutter damper 28 is provided between the flanges 20, 22 to reduce or eliminate flutter arising in blades 18 of the fan at certain important operating conditions. The damper 28 provides flexibility at the connection between the intake section 4 and the containment casing 6 so that, in the event of detachment of a blade 18 or a bladed fragment, the resulting deflection wave in the containment casing 6 can be accommodated by displacement and/or deformation of the acoustic flutter damper 28, reducing the risk that the bolts 50 will shear to allow the intake section 4 and the containment casing 6 to become detached from each other. The acoustic flutter damper 28 may comprise a circumferential array of separate segments 34 ( Figure 3 ).

    摘要: An engine mount, for mounting the casing of an aircraft engine to the fuselage or wing of an aircraft, e.g. via a pylon, comprising first and second links (4, 5) having connector formations for connection to respective mounting formations (3A, 3B) and support formations (7, 8) on the engine casing and aircraft mounting structure. Each of the first and second links (4, 5) is typically connected by a pin between the mounting formations (3A, 3B) and support formations (7, 8). Each link has a further connector formation arranged such that the connector formation of the first link (4) is arranged to be offset from the connector formation of the second link (5). The connector formations are joined by an intermediate link (26). The mount allows lateral forces and torque to be resolved in such a way as to substantially avoid lateral displacement of the engine away from a central plane. The intermediate link (26) may also provide a failsafe catcher arrangement in the event that the first (4) or second (5) link fail.

    摘要: A support ring for a rotary assembly such as a propeller assembly comprises support cups 20 for receiving blade roots 18 of propeller blades 16. The support cups 20 are interconnected by bridging structures 32. Each bridging structure 32 comprises bridging walls 36 which extend radially from a bridging web 38. The bridging structures 32 thus have a channel-shaped cross-section. The bridging walls 36 have a scalloped configuration at their radially outer edges 40. As a result of this configuration, the neutral axes of the bridging structures 36 are straight, so that the support ring 30 behaves, in structural terms, as a polygon.

    摘要: A control mechanism is provided for moving at least two components of a gas turbine engine. The control mechanism comprises a moveable actuation rod. The control mechanism further comprises a first linkage arrangement which includes a first bell crank and which operatively connects the actuation rod to a first component of the gas turbine engine. Movement of the actuation rod produces an output motion of the first bell crank which in turn drives movement of the first component. The control mechanism further comprises a second linkage arrangement which includes a second bell crank and which operatively connects the actuation rod to a second component of the gas turbine engine. Movement of the actuation rod produces an output motion of the second bell crank which in turn drives movement of the second component. The first linkage arrangement and the second linkage arrangement are configured so that over a predetermined range of movement of the actuation rod the first component is moved by the first bell crank while the second component is not moved by the second bell crank.
