    摘要： A system is provided for transmitting data between a first component and a second component, which rotates relative to the first component. The system includes a first coupling element of limited angular extent mounted to the first component, and a second coupling element of limited angular extent mounted to the second component. The first and second coupling elements come into angular alignment once per revolution of the second component relative to the first component. The system further includes a first transceiver connected to the first coupling element, and a second transceiver connected to the second coupling element. The first and second transceivers are configured to detect the angular alignment of the first and second coupling elements. The first and second transceivers are further configured to transmit data between the first and second transceivers via the first and second coupling elements when the angular alignment is detected.

    摘要： A method of detecting shaft break in a gas turbine engine having a shaft system. The shaft system including a shaft that couples a compressor and a turbine. First construct a frequency model of the shaft system. Then determine a notch frequency and a first torsional frequency for the shaft system from the model. Then in real time measure a rotational speed of the shaft; detect the presence or absence of a feature at at least one of the notch frequency and the first torsional frequency in the measured speed; and generate a shaft break signal in response to the absence of at least one of the features.

    摘要： A method of controlling blade pitch angle, including comparing demanded and measured blade pitch angle and calculating any difference therebetween, in a primary electrical control system, where there is a difference, applying torque to a blade pitch regulator to reduce the magnitude of the difference to zero, and in a secondary electrical control system, where the difference is greater than a pre-determined threshold, applying torque to a blade pitch regulator to reduce the magnitude of the difference to the threshold. Also an electrical system of blade pitch angle control for a set of blades including primary and secondary electrical control systems, means for comparing demanded and measured blade pitch angle and calculating any difference therebetween, a look-up function having the difference as its input and outputting a required torque, and a torque regulator to apply the required torque to the set of blades.
