Abstract
A variable turbine inlet nozzle assembly is provided for use in high temperature environments. The nozzle assembly comprises a plurality of vanes and each vane includes a shaft extending outwardly from it. The shafts in turn are rotatably mounted to an annular mounting member so that the vanes are circumferentially spaced from each other and positioned within a gas stream passageway formed within the turbine housing between the combuster and turbine stages. An actuating assembly includes a ring rotatably mounted to the turbine housing concentrically with the mounting member while actuating arms extending between the ring and each shaft selectively rotates or pivots the vanes in unison with each other. Each vane further includes a hollow interior which is fluidly connected with the turbine engine compressor output to provide cooling to and prevent thermal distortion of the vanes.
