There is disclosed a stator vane assembly comprising a support structurearranged to be mounted to a mounting structure, a stator vaneradially extending from the support structureand a continuity membercoupled to the support structureand arranged in use to extend between the mounting structureand the support structureso as to provide a substantially continuous gas-washed surface across the mounting structureand the support structure. There is also disclosed a method of forming a stator vane assembly, the method comprising the steps of forming at least one stator vane radially extending from a support structure having a continuity member coupled thereto.

Stator vane assembly

A mounting arrangement for locating a stator () within a casing () of a rotating machine comprises at least one mounting plate () adapted to engage with the stator () and the casing (). The mounting plate () has a series of discrete apertures () therein. The apertures () extend through the plate () and are arranged in an array to provide a convoluted path which impedes the transmission of the dynamic forces through the plate () and into the casing (). The apertures () render the plate () more resilient to the dynamic forces that the stator () experiences in operation. Each aperture () divides the plate () into portions which provide anisotropic stiffness in the radial and tangential directions.

Mounting arrangement for an electrical machine

A control mechanism is provided for moving at least two components of a gas turbine engine. The control mechanism comprises a movable actuation rod and a first linkage arrangement which includes a first bell crank connecting the actuation rod to a first component. 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 connecting the actuation rod to a second component. 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 and the second linkage arrangements are configure so that over a predetermined range of movement of the actuation rod the first component is moved which the second component is not moved.
