摘要： A turbine nozzle includes first and second vanes joined to outer and inner bands. The vanes include outboard sides defining outboard flow passages containing axial splitlines, and opposite inboard sides defining an inboard flow passage without axial splitline. The two vanes include different cooling circuits for differently cooling the inboard and outboard vane sides.

摘要： A method of extending a useful serviceable life of a gas turbine engine by increasing a limiting exhaust gas temperature margin degraded by engine use without replacing engine hardware. The method includes adjusting at least one engine parameter selected from a first group of engine parameters including a nozzle area and a rotor speed.

摘要： A turbine nozzle for a gas turbine engine subassembly having an axial turbine. The turbine nozzle airfoil-shaped vanes are fixedly attached to one or both of the annular inner and outer casings. Apparatus is provided to vary the vane airflow passage area between the casings and between the pressure side of one vane and the suction side of an adjacent vane. The apparatus varies the area near at least the pressure side of the one vane. Various embodiments of the apparatus include: a small pivotable flap pivotally attached to the outer casing and positioned near the pressure side of the one vane; a small movable flap attached to the outer casing to be movable along the pressure side of the one vane, and a plug member insertable into and withdrawable from the vane airflow passage through the outer casing near at least the pressure side of the one vane.
