FLOW MANIPULATING ARRANGEMENT FOR A TURBINE EXHAUST DIFFUSER
First Claim
1. A flow manipulating arrangement for a turbine exhaust diffuser comprising:
- a strut having a leading edge and a trailing edge, the strut disposed within the turbine exhaust diffuser;
a plurality of rotatable guide vanes disposed in close proximity to the strut and configured to manipulate an exhaust flow, wherein the plurality of rotatable guide vanes is coaxially aligned and circumferentially arranged relative to each other;
an actuator in operative communication with the plurality of rotatable guide vanes and configured to actuate an adjustment of the plurality of rotatable guide vanes; and
a circumferential ring operatively coupling the plurality of rotatable guide vanes, wherein the actuator is configured to directly actuate rotation of one of the rotatable guide vanes, and wherein the circumferential ring actuates rotation of the plurality of rotatable guide vanes upon rotational actuation by the actuator.

Abstract
A flow manipulating arrangement for a turbine exhaust diffuser includes a strut having a leading edge and a trailing edge, the strut disposed within the turbine exhaust diffuser. Also included is a plurality of rotatable guide vanes disposed in close proximity to the strut and configured to manipulate an exhaust flow, wherein the plurality of rotatable guide vanes is coaxially aligned and circumferentially arranged relative to each other. Further included is an actuator in operative communication with the plurality of rotatable guide vanes and configured to actuate an adjustment of the plurality of rotatable guide vanes. Yet further included is a circumferential ring operatively coupling the plurality of rotatable guide vanes, wherein the actuator is configured to directly actuate rotation of one of the rotatable guide vanes, and wherein the circumferential ring actuates rotation of the plurality of rotatable guide vanes upon rotational actuation by the actuator.

15. A flow manipulating arrangement for a turbine exhaust diffuser comprising:
-
an inner barrel extending in a longitudinal direction of the turbine exhaust diffuser; an outer wall disposed radially outwardly of the inner barrel; a strut extending between, and operatively coupled to, the inner barrel and the outer wall, wherein the strut comprises a leading edge and a trailing edge; and at least one guide vane disposed axially upstream of the leading edge of the strut, the at least one guide vane selectively circumferentially displaceable relative to the strut. - View Dependent Claims (16, 17, 18, 19)

20. A flow manipulating arrangement for a radial turbine exhaust diffuser comprising:
-
an inner wall; an outer wall; a strut operatively coupled to at least one of the inner wall and the outer wall; and at least one rotatable guide vane disposed proximate the strut, wherein the at least one rotatable guide vane is selectively rotatable over a range of angular positions and displaceable in at least one of an axial direction and a radial direction.
