    摘要： A fiberoptic multi-parameter sensing system for monitoring turbomachinery system shaft static and dynamic torques, vibration modes and associated operation status includes a multi-furcated fiber bundle based optical splitter configured to transmit light to a surface of at least one turbomachinery system shaft through a plurality of optical fiber bundles disposed at a plurality of locations in proximity to the surface of the at least one shaft, in which the plurality of locations together are arranged in a substantially axial direction between the ends of the at least one shaft. The system further includes an array of high-temperature bifurcated fiber bundle based reflectance probes to receive reflectance signals from the shaft surface and send to an array of photosensitive detectors, configured to detect dynamic light reflected from the at least one turbomachinery system shaft surface in response to the transmitted light during rotation of at least one turbomachinery system shaft and generate dynamic reflected light signals there from. A sensing mechanism is configured to determine a torque or vibration on at least one turbomachinery system shaft in response to the dynamic reflected light signal signatures based on time-domain and frequency-domain signal processes.

    摘要： A method and system suitable for inferring trajectory predictor parameters of aircraft for the purpose of predicting aircraft trajectories. The method and system involve receiving trajectory prediction information regarding an aircraft, and then using this information to infer (extract) trajectory predictor parameters of the aircraft that are otherwise unknown to a ground automation system. The trajectory predictor parameters can then be applied to one or more trajectory predictors of the ground automation system to predict a trajectory of the aircraft. In certain embodiments, the method and system can utilize available air-ground communication link capabilities, which may include data link capabilities available as part of trajectory-based operations (TBO).

    摘要： A method of estimating a clearance between at least one rotating object of a rotary machine and a second object is provided. The method includes measuring an operating parameter of the rotary machine. The method also includes obtaining signals corresponding to the at least one rotating object across multiple revolutions in time, wherein the number of the revolutions is determined based upon the measured operating parameter. The method further includes generating waveforms corresponding to the at least one rotating object from the obtained signals for the revolutions. The method also includes estimating the clearance between the second object and the at least one rotating object based upon the generated waveforms.
