    摘要： A composite section including a concentric arrangement of inner and outer laminates having an interstice therebetween is provided. Both the inner and outer laminates include a matrix material and a fabric layer. A plurality of tubes having an inner cavity, are situated in the interstice of the inner and outer laminates. A reinforcing material is disposed in the interstice and along the length of the concentric arrangement unoccupied by the plurality of tubes to create a composite section. A plurality of tension members are threaded though the plurality of tubes to provide post tensioning to each of the composite sections. The components are easily transported and assembled to form composite sections to provide cost effective on-site tower formation. Also provided is an apparatus to form the inner and outer laminates and a method of formation of the composite section.

    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.
