    摘要： The object of the invention is to suppress development of a secondary current whirl in the vicinity of a rotor blade front edge of a gas turbine even when a cooling refrigerant is mixed in from the front edge of an end wall section of the rotor blade. In a gas turbine rotor blade 4 including a wing shape section 12 formed of a negative pressure surface 12d extending from a front edge 12a to a rear edge 12b, a pressure surface 12c opposing the negative pressure surface 12d and extending from the front edge 12a to the rear edge 12b, and a tip surface 13 surrounded by the top end of the negative pressure surface 12d and the top end of the pressure surface 12c, and an end wall section 10 connected to the bottom end of the negative pressure surface 12d and the bottom end of the pressure surface 12c, the rotor blade has a convex shape in positions constituting the negative pressure surface 12d side and the front edge 12a side of the end wall section 10, and the rotor blade has a concave shape in positions constituting the pressure surface 12c side and the front edge 12a side of the end wall section 10.

    摘要： An airfoil includes an airfoil body that defines a longitudinal axis. The airfoil body includes a leading edge and a trailing edge and a first side wall and a second side wall that is spaced apart from the first sidewall. The first side wall and the second side wall join the leading edge and the trailing edge and at least partially define a cavity in the airfoil body. At least one of the first side wall and the second side wall includes at least one longitudinally elongated buttress that tapers longitudinally. The at least one longitudinally elongated buttress defines an increased thickness of, respectively, the first side wall or the second sidewall. The at least one longitudinally elongated buttress projects partially across the cavity toward the other of the first side wall or the second sidewall.

    摘要： A bucket assembly (30) cooling apparatus is provided. The bucket assembly (30) includes a platform (32), an airfoil (34), and a shank (36). The airfoil (34) may extend radially outward from the platform (32). The shank (36) may extend radially inward from the platform (32). The shank (36) may include a pressure side sidewall (42), a suction side sidewall (44), an upstream sidewall (46), and a downstream sidewall (48). The sidewalls (42, 44, 46, 48) may at least partially define a cooling circuit (90). The cooling circuit (90) may be configured to receive a cooling medium (95) and provide the cooling medium (95) to the airfoil (34). The upstream sidewall (46) may at least partially define an interior cooling passage (80) and at least partially define an exterior ingestion zone (70). The cooling passage (80) may be configured to provide a portion of the cooling medium (95) from the cooling circuit (90) to the ingestion zone (70) of an adjacent bucket assembly (30).

    摘要： A rotary energy generating device includes an output shaft, a rotor coupled to the output shaft, and a plurality of paddles coupled to the rotor, with each paddle being moved between vertical and horizontal positions as the rotor is rotated. A chamber housing includes inlet and output pairs. A respective open chamber area is defined between each inlet and outlet pair based on a given rotation direction of the rotor, with each respective open chamber area configured to receive the paddles in the vertical position as the rotor rotates in the given rotation direction. A respective slotted chamber area is defined between each outlet and inlet pair based on the given rotation direction of the rotor, with each respective slotted chamber area configured to receive the paddles in the horizontal position as the rotor rotates in the given rotation direction.

    摘要： A telemetry system for use in a combustion turbine engine (10) having a compressor (12), a combustor and a turbine (16) that includes a sensor (306) in connection with a turbine blade (301) or vane (22). A telemetry transmitter circuit (312) may be affixed to the turbine blade with an electrical connecting material (307) for routing electronic data signals from the sensor (306) to the telemetry transmitter circuit, the electronic data signals indicative of a condition of the turbine blade. A resonant energy transfer system for powering the telemetry transmitter circuit may include a rotating data antenna (314) affixed to the turbine blade or on a same substrate as that of the circuit. A stationary data antenna (320) may be affixed to a stationary component such as a stator (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna.
