Abstract
A vane assembly is shown for a relatively short annular transition zone directing the discharge of the working fluid from the compressor turbine to a single stage power turbine in a gas turbine engine. The annular transition zone comprises a plurality of individual arcuate segments having a pair of stationary vanes integrally molded to inner and outer shroud members. A variable vane is disposed immediately downstream of each stationary vane for guiding the working fluid into the power turbine at an optimum angle. The variable vanes are manually adjustable from outside the turbine casing through a linkage and support mechanism that maintains a constant clearance between the variable vane and the shroud members and also accommodates variations in dimensional relationships due to temperature variations. Also, provision is made for centering the axis of the variable vanes to a precise position with respect to the stationary vane to accommodate the buildup of assembly tolerances.
