    摘要: A method of controlling settings of one or more actuatable gas turbine engine components includes: providing a first matrix which relates reduction in the operational parameter maximum value during the transient manoeuvre to settings of the component(s); providing a second matrix which relates the operational parameter maximum values attained during the transient manoeuvre: time to attain the maximum value after transient manoeuvre initiation, and operational parameter rate of change at the time of the maximum value; monitoring the engine in operation to identify a start of a transient manoeuvre; predicting, on the basis of the second matrix maximum values, an overshoot operational parameter amount during the identified transient manoeuvre and a time the overshoot occurrence; selecting a setting, using the first matrix, to eliminate the predicted overshoot; and applying the setting to the component(s) for a predetermined period around the predicted time of occurrence to reduce or avoid the overshoot.

    摘要: A heat exchange arrangement (40) for a gas turbine engine (10). The arrangement (40) comprises a first conduit (46) for an engine component cooling fluid and a second conduit (44) for a second fluid. The arrangement further comprises a heat exchange portion (42) in which fluids flowing through the first and second conduits (46, 44) are in a heat exchange relationship. A valve 48 is provided, which is configured to moderate the mass flow rate of one of the fluids through the heat exchange portion (42). The arrangement comprises a temperature sensor (50) configured to sense a temperature of one of the fluids after said fluid has passed through the heat exchange portion (42) and a controller (52). The controller (52) is configured to control the valve (48) in response to a rate of change of the temperature with respect to time of the fluid sensed by the temperature sensor (50).

    摘要: A turbine and method for determining turbine maintenance. The method for determining hot gas path turbine maintenance comprises recording a number of part load starts (79), base load starts (89), fast starts (141), full speed no load trips (231), and load trips (237); forming a weighted equivalent starts as a weighted summation of part load starts, base load starts, fast starts, full speed no load trips, and load trips; comparing the weighted equivalent starts to a predetermined threshold; and initiating the maintenance procedure. The method for determining rotor parts turbine maintenance comprises recording the number of fast starts, normal starts (143), and elapsed time starts (135) from shutdown to restart; forming a weighted equivalent starts as a weighted combination of fast starts, normal starts, and elapsed time starts from shutdown to restart; comparing the weighted equivalent starts to a predetermined threshold; and if a weighted equivalent starts exceeds the predetermined threshold, initiating the maintenance procedure.
