    摘要： A bolt connection assembly is provided that is particularly suited for connecting components of a lattice structure wind tower. The assembly includes a pin component having a head and a shaft, with the shaft having a textured friction-fit outer circumferential surface. The shaft further includes a threaded internal bore. A bolt component having a threaded shaft engages within the threaded internal bore. In an assembled state of the pin component and bolt component, the threaded shaft has a free length section that extends into the threaded internal bore for increased distribution of a specified pretension of the bolt component.

    摘要： A wind turbine blade instrumentation structure and method is provided for fluid dynamic polymer-based contact sensors measuring ambient pressure based on the resistivity changes across the sensor. The pressure sensors may applied in predetermined patterns to airfoil structures, such as wind turbine blades, without impacting the blade structure and fluid dynamic characteristics. The pressure sensors measure blade performance with high fidelity. The pressure measurements are transmitted to processing to determine blade characteristics and environment including flow separation, stagnation point, angle of attack, lift and drag and wind speed. Further processing of the pressure distribution may identify wind shear, up-flow and yaw error.

    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.
