ABSTRACT:
A turbine assembly is provided by which a variable area turbine vane may be cantilever mounted from an outer structural frame and further supported by an inner structural frame. The vane includes an inner trunnion about which is installed an inner band sector to partially define a flow path through the turbine. The band sector is provided with a hole which receives the trunnion. Once the vane is cantilevered from the outer frame and the band sector installed, an inner annular frame is slid under the vane trunnion to align a hole in the frame with the trunnion. A generally cylindrical trunnion extension is inserted through the frame hole and over the end of the trunnion, and then attached to the trunnion through a bolted connection. The extension is journaled for rotation within the inner structural frame hole. Passageways are provided to route cooling air from the vane into the structural frame to provide cooling of the band sector. Such a structure eliminates the need for expensive uniballs or matched assembly halves at the inner end of the turbine vanes.
