    • A method of assembling and manufacturing a laminated rotor is provided which uses laminations (102, 500) having a thin bridge thickness (d). Different techniques are provided for preventing the molten material used in the casting or injection molding operation from leaking or seeping between the laminations (102, 500) during casting. In one technique, the laminations (102) are stacked and oriented in the conventional way, and then both axial and radial pressures (F A , F R ) are applied to the stacked laminations (102) to hold the laminations (102) in position for the casting process. In another technique, the laminations (500) are formed or extruded with a lip or collar portion (508) that fit in a countersunk portion (506) of an adjacent lamination (500) and forms a wall or barrier between the laminations (500) to prevent the leakage of the molten material during the casting or injection molding operation.

    • Turbine section (26) vane ring (44, 46) swallowing capacity, or throat cross section is selectively varied, through use of bi-cast vanes (50). The bi-cast vanes share a common, prefabricated vane airfoil profile (52), as well as subsequently cast outer diameter/upper (54) and inner diameter/lower vane (56) platforms. Throat cross section (T) between pairs of opposed vane airfoils (52) is selectively varied, prior to vane casting, by changing orientation of the prefabricated airfoil within corresponding vane platform molds (60). Vane ring (44, 46) swallowing capacity is readily adjusted, to meet ambient air pressure operating conditions at different plant altitudes, or different fuel caloric content properties (e.g., natural gas or coal gas). Airfoil (52) orientation is varied locally about the vane ring (44, 46), to adjust for local variances in combustion gas mass-flow or flow direction caused by locally varying physical constraints within the engine (20).
