초록

A variable area turbine nozzle includes a plurality of circumferentially adjoining nozzle segments. Each nozzle segment includes outer and inner bands, with a plurality of first vane segments fixedly joined therebetween. A plurality of second vane segments adjoin respective ones of the first vane segments to define therewith corresponding vanes which are spaced apart to define respective throats of minimum flow area for channeling therethrough combustion gas. The second vane segments are pivotable to selectively vary the throat area.
