摘要： A rotor cooling circuit includes a cooling medium supply reservoir for supplying cooling medium to a plurality of axial passages through the turbine wheel and spacer disc rims. A passageway communicates cooling medium from the reservoir for flow in series and in a serpentine manner in and about the cavities between the wheels and discs. The flows are reunited at a plenum for flowing the cooling medium into first and second stage buckets. Return passages through the rims of the wheels and spacer discs return spent cooling medium from the buckets to a return location external of the rotor. Transition elements between the buckets and spacer plates in the rotor rim accommodate any thermal mismatch between the adjoining buckets and spacer plates to prevent cooling medium leakage at the joints.

摘要： A gas turbine rotor assembly (10) includes axially spaced rotor discs (18,20,22) carried on a shaft (12), together with first and second generally cylindrical actuators (40,42) mounted at each of their opposite ends to the shaft (12) and extending toward one another to overlap at their distal ends. The actuators (40,42) lie within the interior surface of the rotor discs (18-22) and have openings (48 and 50) in their overlapped portions. Upon a transient condition, the forward actuator (40) thermally expands in an axial direction to register at least in part its openings with the openings of the second actuator (42) to provide air flow through the partially aligned openings to opposite sides of an aft rotor disc (20,22). The second actuator (42) thermally expands in a forward axial direction to increase the registration of the openings and, hence, the flow-through area, affording increased air flow. When approaching steady state operation, the rotor assembly expands axially to displace the openings of the second actuator into misalignment with the openings of the first actuator to prevent the flow of air through the openings, whereby cooling losses during steady state operation are avoided.

摘要： The steam transfer arrangement includes dovetail connections between a turbine bucket 14 and rotor wheel 12 wherein a steam supply passage 20 in the rotor wheel registers with a steam cooling passageway 28 in the bucket and a steam return passageway 30 in the bucket lies in registry with a steam return passage in the wheel. At the interface of the dovetail connection, each registering passage and passageway includes a sleeve 50, 52 disposed in an enlarged recess 54, 56, the sleeves having annular spherical sealing surfaces for engagement with annular spherical seats on the turbine bucket. The sleeves are compressible radially relative to the bucket to enable the bucket to be secured to the wheel and expand radially outwardly to ensure sealing fit between the sealing surfaces and seats.

摘要翻译：燃气轮机转子组件（10）包括承载在轴（12）上的轴向间隔开的转子盘（18,20,22），以及安装在其每个相对端处的第一和第二大致圆柱形致动器（40,42）轴（12）并且彼此相对延伸以在其远端处重叠。致动器（40,42）位于转子盘（18-22）的内表面内并且在其重叠部分中具有开口（48和50）。在瞬态状态下，前进致动器（40）在轴向方向上热膨胀以至少部分地将其开口与第二致动器（42）的开口对准，以提供通过部分对准的开口的空气流到尾部的相对侧转子盘（20,22）。第二致动器（42）在向前的轴向方向上热膨胀以增加开口对准，从而增加流通面积，从而提供增加的气流。当接近稳态操作时，转子组件轴向膨胀以将第二致动器的开口移动到与第一致动器的开口不对准，以防止空气流过开口，从而避免在稳态操作期间的冷却损失。

摘要： The present invention provides for the removable attachment of sealing segments about the entire circumferential periphery of the rotor spacer discs. To this end, the conventional annular grooves provided in the peripheral surface of each spacer disc (as part of the high/low sealing surface configuration) are reconfigured as dovetail grooves which are designed to receive complimentary or mating portions of the sealing segments. In other words, each adjacent annular groove receives a plurality of sealing segments, the totality of which substantially prevent or at least minimize the impingement of hot gases directly on the peripheral surface of the spacer disc.
