    摘要: One embodiment includes a system including an actuation system of a gas turbine system including an actuator, a positioner including one or more sensors, a motor, and a controller communicably coupled to the positioner and the motor. The actuator is coupled to one or more inlet guide vanes (IGVs) or variable stator vanes (VSVs) and configured to move the IGVs or VSVs, the positioner is configured to position the actuator so that the actuator moves the IGVs or VSVs to a desired angle, the motor is configured to drive the actuator, and the controller is configured to establish one or more baselines for one or more types of data obtained by the sensors at initialization of the gas turbine system, derive a deviation from the baselines, and perform a preventative action if a deviation that meets or exceeds a threshold is derived.

    摘要: A method and system for determining creep capability of turbine components is provided. A plurality of turbine components are manufactured from a material having known creep characteristics. Each of the plurality of turbine components is subjected to at least one of tensile stress, centrifugal stress and thermal stress, until a measurable amount of creep is acquired. The turbine components so tested are compared against known creep characteristics for the material used in the components. Components exhibiting an amount of creep greater than a predefined amount of creep will be separated from the plurality of turbine components and not placed into service.

    摘要: A method and system for monitoring a gas turbine engine (20) to predict maintenance requirements. Particles suspended in a gas flow (24, 32) of the engine (20) are monitored and quantified to predict a particle accumulation rate. Monitoring may be done using particle flow sensors (61-63) in a diverted portion (33) of the working gas flow (24), such as in the cooling gas flow (32). Particle sampling (S1-S3) may be done to determine particle size and composition distributions. Particle mass flow rates may then be continuously monitored per engine operating condition, and compared to predetermined values such as a normal upper limit per engine operating condition. An integrated particle mass flow may be used in conjunction with an instantaneous mass flow rate to predict a maintenance requirement. Multiple locations (L1-L3) may be monitored to recognize a maintenance requirement by flow section or component.

    摘要: A self-contained temperature probe assembly for sensing the disc cavity temperature of a gas turbine engine is shown. The assembly includes a thermocouple probe comprising an upper tube and a lower tube housing the probe leads. The lower tube extends from the cylinder housing through the blade ring to guide the probe tip through a hollow vane to adjacent a rotor disc and includes a tapered portion for sealing engagement with a tapered aperture in the blade ring as biased by a coil spring. The upper tube extends outwardly from the turbine cylinder to the probe head. The adjacent ends of the two tubes are retained in a standard flange in predetermined spaced relation against outward withdrawal and the lead wires are coiled within the space to maintain a slack condition to prevent transmission of vibration of the lead wires into the probe head and also prevent the rather fragile wires from supporting any weight of the probe during shipping or installation of the probe to the turbine.
