National Rotor Testbed Functional Scaling Presented at American Institute of Aeronautics and Astronautics 2014 Scitech

David Maniaci (in Sandia’s Wind Energy Technologies Dept.) traveled to National Harbor, Maryland, in January to present a paper at the American Institute of Aeronautics and Astronautics (AIAA) SciTech/American Society of Mechanical Engineers Wind Energy Symposium titled, “Definition of the National Rotor Testbed: An Aeroelastically Relevant Research-Scale Wind Turbine Rotor.” Approximately 60 researchers from various institutions […]

Scaled Wind Farm Technology Facility Baselining Project Accelerates Work

With the Scaled Wind Farm Technology (SWiFT) facility’s basic operation and data collection now operational, the SWiFT Baselining Team met at Sandia on February 20th to kick-off the SWiFT Facility Baselining Project’s major work phase. The project’s goal is to achieve complete operational readiness and verification of all SWiFT controller, data acquisition, and instrumentation systems for future […]

Increasing the Scaled Wind Farm Technology Facility’s Power Production

During the period of February 24–March 7, Scaled Wind Farm Technology (SWiFT) facility turbines were operational—producing power and collecting data for the longest period to date. On March 5, both turbines produced rated power of 200 kW without any issue. A snapshot of 184 kW is shown in the figure. To date, the turbines have been running with supervised operation […]

Characterizing Scaled Wind Farm Technology Facility Inflow

The Scaled Wind Farm Technology (SWiFT) research facility will provide meteorological measurement advanced of the industry standard. Two anemometer towers have been installed 2.5 rotor diameters upstream of the first row of wind turbines. When fully instrumented, these towers will provide both the industry standard averaged value (wind speed and direction, i.e., two-dimensional wind vector) and […]

New Material Tests Show Biaxial Laminate Creep Is Important for Large Wind-Turbine Blades

Blade designers continue to push existing composite material capabilities  as they look to capture more wind with longer rotors. Recent industry observations of damage occurring earlier than expected in the blade panel regions (Figure 1) were brought to the attention of researchers at Sandia National Laboratories and Montana State University (MSU). Blade panel regions typically use […]
